To achieve successful learning outcomes, language learners need to regulate their emotions and sustain positive emotions during the col- laborative learning process. This study investigated language learners’ emo- tion regulation and enjoyment, the most extensively researched positive emotion in foreign language learning, in an online collaborative English learn- ing environment. In the study, we collected data by surveying 336 Chinese Zhipeng Zhang, Xuesong (Andy) Gao, Ting Liu, Chwee Beng Lee 460 students majoring in English who collaboratively completed a series of English language writing tasks in 108 online groups facilitated by a social media app (WeChat). Principal component analysis revealed two primary types of emotion regulation: peer regulation and group regulation. The analysis also revealed one factor underpinning enjoyment: enjoyment of online collaboration. Correlation analysis showed medium and positive relationships between peer regulation, group regulation, and enjoyment of online collaboration. Structural equation modeling analysis further found that group regulation exerted a medium-sized direct effect on enjoyment of online collaboration. Peer regulation affected en- joyment of online collaboration moderately and indirectly via group regulation. The theoretical and pedagogical implications of the findings can help to opti- mize face-to-face and online collaborative language learning activities.

Introduction Learning a foreign language (FL) is not only a cognitive process but also an emo- tional one (Swain, 2013). Positive emotions help FL learners explore learning oppor- tunities and take risks in unfamiliar cultural and linguistic contexts, which helps to develop their language competence (Jiang & Dewaele, 2019). In FL learning, enjoy- ment is one of the most prevalent positive emotions experienced by learners (Jiang & Dewaele, 2019; Li et al., 2018; Piniel & Albert, 2018). Recent studies uncovered a range of learner-internal (e.g., age, education level, and FL proficiency level) and learner-external (e.g., teachers’ friendliness and classmates’ support) variables that influence enjoyment (Dewaele & MacIntyre, 2014; Dewaele et al., 2019). However, these studies were classroom-based, even though one of the primary aims of FL learning is to communicate with others outside the classroom. In the modern era, learning is highly interactive, collaborative, and tech- nologically enhanced (Järvenoja et al., 2015). Online collaborative learning is ef- fective for learners’ FL development (Kukulska-Hulme & Viberg, 2018). However, as Yoshida (2020) indicated, few studies have explored how language learners’ emotions unfold and develop during online collaboration. In online collabora- tive learning, positive emotions such as enjoyment are needed to maintain the productive co-construction of language knowledge (Poehner & Swain, 2016). Given that emotions may exhibit different patterns (e.g., factor/conceptual structure) across different language learning contexts (Dewaele & MacIntyre, 2016; Li et al., 2018), more studies are needed to explore the unique pattern of positive emotions, especially enjoyment, in the specific context of online collab- orative learning. Moreover, emotions are not a product of the mind but are also Language learners’ emotion regulation and enjoyment in an online collaborative writing program 461 regulated and constructed from interpersonal interactions (Swain, 2013). In an online setting, a positive emotional climate is more difficult to achieve because non- verbal emotional cues (e.g., facial expressions) that are abundant in face-to-face in- teractions are usually absent (Dunlap et al., 2016). Thus, learners may need to spend more time and energy regulating their emotions during online collaborative activities than they would in face-to-face interactions to be emotionally satisfied. To understand the emotional aspect of online collaborative language learning, the present study investigated the primary types of emotion regulation, the unique factor structure of enjoyment, and how different types of emotion regulation interacted to increase enjoyment among English as a foreign lan- guage (EFL) learners who completed a series of online English writing tasks in collaboration at a Chinese university. In the coming sections, we review relevant studies on emotion regulation and FL enjoyment. 2. Literature review 2.1. Emotion regulation Emotion regulation refers to the processes involved in recognizing, understanding, and managing one’s emotions, including modulating, preventing, or inducing them for action and goal achievement (Pekrun, 2006; Von Scheve, 2012). Emotion regulation plays an important role in the self-regulated learning process because it monitors, changes, modifies, and maintains the valence, duration, and intensity of learners’ emotions (Boekaerts, 2011). Such regulation often leads to the growth of positive emotions and the reduction of negative emotions in learning, which supports learners’ academic achievement and well-being (Pekrun, 2006). Emotion regulation has been subject to numerous empirical investiga- tions from an intrapersonal perspective of self-regulation (e.g., Boekaerts, 2011; Gross, 1998). However, there have recently been calls to incorporate an inter- personal perspective on emotion regulation in contexts such as face-to-face col- laborative learning (Järvenoja et al., 2015; Järvenoja et al., 2013). For example, using the Adaptive Instrument for Regulation of Emotions, a scale developed by Järvenoja et al. (2013) to measure emotion regulation processes, Järvenoja and Järvelä (2009) explored how emotions were regulated to cope with challenging situations. They examined 63 teacher education students in Finland who studied in groups of three to five during three collaborative learning tasks. The results suggested that, when students worked collaboratively, they assisted each other’s regulation (co-regulation) and shared their regulatory efforts with others (socially shared regulation) while regulating themselves (self-regulation). Näykki et al. (2014) further explored the relationships between emotion regulation and Zhipeng Zhang, Xuesong (Andy) Gao, Ting Liu, Chwee Beng Lee 462 emotional challenges by combining video observation data and video-stimu- lated recall interview data collected from collaborative learning processes of 22 students majoring in education in Finland. This study revealed that, in the face of socioemotional challenges that disrupted a group’s positive climate, insuffi- cient shared efforts within the group to regulate emotions could undermine group members’ enjoyment and engagement in collaborative learning. Rogat and Adams-Wiggins (2015) examined the interrelations between regulatory pro- cesses and socioemotional interactions through observations of videotaped col- laboration in two four-member groups of middle school students (N = 8) in the United States. Results indicated that facilitative other-directed regulation, such as being inclusive of others’ ideas, contributed to a balanced regulation among group members and fostered positive social interactions. Based on the video- recorded data gathered from 62 teacher education students in Finland who col- laborated in groups during a mathematics course, Järvenoja et al. (2019) re- vealed how students employed strategies to regulate their emotions at the group level. A variety of regulatory strategies, including encouragement, aware- ness increasing, social reinforcement, and task structuring, were adopted by learners at the group level to ease the tension caused by challenges and create a positive environment for knowledge co-construction. Similarly, Mänty et al. (2020) asserted that group-level regulation could effectively shift a group’s emo- tional atmosphere from negative to positive. The data were collected using video recordings of collaborative activities and an emotion self-report tool among 37 primary school students in Finland. Emotion regulation in face-to-face collaborative activities was found to function beyond self-regulated mecha- nisms, operating to achieve and maintain a positive emotional climate that sup- ported effective group learning (Hadwin et al., 2018; Järvenoja et al., 2015). Researchers also paid attention to emotion regulation in language learn- ing. Using a scenario-based questionnaire filled out by 133 English major learn- ers in Poland, Bielak and Mystkowska-Wiertelak (2020a) identified that lan- guage learners up-regulate positive and down-regulate negative emotions by implementing specific strategies, such as cognitive change, situation modifica- tion, attention deployment, and response change. Importantly, the above study focused on language learners’ emotion regulation in the classroom language learning context. Research on emotion regulation in online collaborative lan- guage learning has been limited (Järvelä et al., 2015). The lack of non-verbal behaviors and relational cues, such as facial expressions and the use of hands, in online collaborative learning makes it more difficult to establish a positive at- mosphere during interactions than in face-to-face settings (Dunlap et al., 2016). Emotion regulation is context-bound and situated in specific learning situations (Järvenoja et al., 2015). Therefore, a different pattern of emotion regulation may Language learners’ emotion regulation and enjoyment in an online collaborative writing program 463 arise in online collaborative learning to sustain a favorable emotional climate for productive online collaborative language learning. To build on these considera- tions, this study aims to identify the types of emotion regulation that emerge and how these types of emotion regulation affect enjoyment during online col- laborative language learning. 2.2. Foreign language enjoyment Enjoyment is a complex positive emotion that incorporates various dimensions in addition to a pleasurable feeling, such as “an intellectual focus, heightened attention, and optimal challenge” (Boudreau et al., 2018). In other words, en- joyment refers to a sense of novelty or accomplishment from pushing oneself to earn an unexpected achievement in the face of challenging tasks, such as learning (Csikszentmihalyi, 2008). Csikszentmihalyi (2000) perceived enjoyment as a key component of the flow experience that enhanced learners’ engagement in learn- ing activities. Based on Fredrickson’s (2003) broaden-and-build theory of positive emotions, MacIntyre and Gregersen (2012) argued that positive emotions like en- joyment could broaden learners’ perspectives and assist them in effectively ab- sorbing an FL. In addition, enjoyment helps to reduce the lingering effect of neg- ative emotions, promoting long-term resilience and well-being in the future (Li et al., 2018). An increasing number of studies confirmed the positive effect of language learning enjoyment on learners’ willingness to communicate (Dewaele & Dewaele, 2018; Khajavy et al., 2018), language learning grit (Pawlak, Csizér, et al., 2022), language motivation (Pawlak, Zarrinabadi, et al., 2022), language fluency (Bielak, 2022), language performance (Dewaele & Alfawzan, 2018; Saito et al., 2018), and language achievement (Jin & Zhang, 2018; Li et al., 2019) in various contexts. Dewaele and MacIntyre (2014) were the first to develop a 21-item FL en- joyment scale. They used the enjoyment scale to examine the potential varia- bles influencing FL enjoyment of 1746 language learners from all around the world in classroom learning. Their results suggested that learners who were older, multilingual, more educated, and more proficient in the target languages tended to experience more enjoyment than those with the opposite qualities. Based on the principal component analysis of the same dataset (N = 1746), Dewaele and MacIntyre (2016) modified the original 21-item scale into a 14- item version and identified a two-factor structure of FL enjoyment: FL enjoyment – Social and FL enjoyment – Private. These two factors showed that the social atmosphere of the language classroom and learners’ private thoughts influenced enjoyment. Via a series of exploratory and confirmatory factor analyses of the scale data gathered from 2078 high school learners in China, Li et al. (2018) fur- ther modified the 14-item scale into an 11-item version in the Chinese EFL context. Zhipeng Zhang, Xuesong (Andy) Gao, Ting Liu, Chwee Beng Lee 464 In findings that differed from the two-factor structure in the study of Dewaele and MacIntyre (2016), a three-factor structure was confirmed by Li et al. (2018) in the 11-item version, that is, FL enjoyment – Private, FL enjoyment – Teacher, and FL enjoyment – Atmosphere. The results of such studies indicated that the factor structure of enjoyment might differ depending on the context in which the con- struct is investigated (Dewaele & MacIntyre, 2016). However, these studies focused narrowly on traditional classroom language learning settings (e.g., Dewaele & MacIntyre, 2014; Li et al., 2018). Few investiga- tions of enjoyment have been performed in an online collaborative language learn- ing environment, where knowledge and emotion are built up through group inter- action facilitated by online technology (Bakhtiar et al., 2018). Enjoyment varies across different language learning situations (Dewaele & MacIntyre, 2016; Piniel & Albert, 2018). Therefore, the above factor structures of enjoyment identified in classroom learning may not fit in online collaborative learning. As a result, it is nec- essary to examine the factor structure of enjoyment in the present study. Moreover, emotions are not private (intrapsychic) but are constructed or regulated interper- sonally through interactions (Poehner & Swain, 2016; Swain, 2013). This could also be the case for enjoyment. Although the studies reviewed above identified numer- ous learner-internal (e.g., age and educational level) and learner-external variables (e.g., teacher and social atmosphere) that influence enjoyment, none of them in- vestigated how learners regulated their emotions to experience enjoyment in inter- actions. This has motivated us to take a regulative perspective to further investigate language learners’ enjoyment during online collaboration. Specifically, the present study addresses the following research questions: 1. What are the major types of emotion regulation, and what is the factor structure of enjoyment of Chinese English-major students during an online collaborative EFL writing program? (RQ1) 2. What are the relationships between different types of emotion regula- tion and enjoyment during the program? (RQ2) 3. In what ways do the participants enact different types of emotion regu- lation to increase their enjoyment during the program? (RQ3) 3. Method 3.1. Participants and context The participants were 336 second-year English majors (310 females, 26 males) at a provincial comprehensive university in Northern China. Their ages ranged from 18 to 22, with a mean age of 19.72 years (SD = .89). They were all Chinese Language learners’ emotion regulation and enjoyment in an online collaborative writing program 465 L1 users and studied English as their only FL from seven to ten years. Their Eng- lish proficiency ranged from lower intermediate and intermediate to higher in- termediate based on their final grades in the previous semester’s English profi- ciency exam (M = 73.91 out of 100; SD = 11.01). Their English writing ability was also between lower intermediate and higher intermediate based on their self- perceptions on the 5-point Likert scale (M = 3.14; SD = .86). By majoring in Eng- lish, participants regularly took various English language courses (e.g., writing and reading) and content courses (e.g., applied linguistics and literature of Eng- lish-speaking countries) in the classroom. Participants, as sophomores, were required to attend a semester-long ex- tracurricular program consisting of a series of online collaborative English writing activities. The program was exam-oriented, aiming to help learners prepare for the Test for English Majors Band 4 (TEM4), a national English language proficiency test mandatory for second-year English majors in China. During a semester (18 teaching weeks in total), participants worked on about ten possible writing tasks of TEM4 in three-to-four-member online groups. A total of 108 online groups were formed randomly by participants using WeChat, a popular social communi- cation app where users can share messages, photos, and videos free of charge (Zou et al., 2018). On WeChat, teachers posted writing tasks and collected groups’ assignments on approximately a weekly or fortnightly basis. The writing tasks usu- ally required participants to compose essays of at least 200 words based on a 200- word piece of reading material. The writing topics differed weekly or fortnightly, including the pros and cons of artificial intelligence, the protection of local culture, the problems of media use, and others. Within WeChat groups, learners were en- couraged to freely organize online meetings, search for online resources together, exchange thoughts, and collaboratively complete writing tasks assigned by teach- ers before the due date. The duration of online meetings on WeChat differed for most of the groups and was between 20 and 50 mins per week. The ten collabo- rative English writing assignments together accounted for 30% of learners’ final grades in the English writing course. 3.2. Instruments A composite questionnaire that contained 22 5-point Likert items in total was used in this study. It began with a sociodemographic section (e.g., age, gender) followed by two well-established scales: the Adaptive Instrument for Regulation of Emotions (AIRE) (Järvenoja et al., 2013) and the Foreign Language Enjoyment Scale (FLES) (Jiang & Dewaele, 2019). The translation and back translation of the questionnaire were conducted by the first author and another Chinese-English bilingual researcher. Twelve second-year English major students at the same university were invited to Zhipeng Zhang, Xuesong (Andy) Gao, Ting Liu, Chwee Beng Lee 466 help assess whether the participants would potentially misunderstand the items. Based on their comments, further revisions were made before the final version of the questionnaire was posted online using Qualtrics, an online survey tool. In addi- tion to the translated Chinese version, the original English version was also provided in Qualtrics, and participants could choose which version they wished to complete. The two scales are described in more detail in the subsections below. 3.2.1. Adaptive Instrument for Regulation of Emotions (Järvenoja et al., 2013) The AIRE scale is grounded in self-regulated and socially regulated learning theory and is used to capture learners’ emotion regulation processes in collaborative learn- ing activities (Järvenoja et al., 2013). The scale includes 12 5-point Likert items re- flecting different types of emotion regulation, such as self-, co-, and socially shared regulation, which learners may enact during their collaborative learning. Example items are: “I convinced myself that it could be a good thing to have differences in the group,” “I told the others that we needed to accept that some people did have differences,” and “As a group, we accepted the differences within the group.” The 5-point response options for the 12 items range from 1 (“Did not happen at all”) to 5 (“Did happen a lot”). A higher score indicates more frequent use of item-related regulation activities. High internal reliability of the scale (Cronbach’s ɑ value = .85 and .86) was reported by Järvenoja et al. (2013) at two measurement points, two weeks apart, in a face-to-face collaborative learning context. 3.2.2. Foreign Language Enjoyment Scale (Jiang & Dewaele, 2019) Jiang and Dewaele’s (2019) FLES, which was used to measure enjoyment in the pre- sent study, is a modified version of the original foreign language enjoyment scale developed by Dewaele and MacIntyre (2014) using 1746 FL learners worldwide. The scale includes ten items reflecting both social and private factors of enjoyment iden- tified in Dewaele and MacIntyre (2016). Example items are: “It was cool to know English as a foreign language” and “There was a good atmosphere.” All ten items are scored on a 5-point Likert style scale ranging from 1 (“Strongly disagree”) to 5 (“Strongly agree”), with the higher score indicating a higher level of enjoyment. In the context of a Chinese university, Jiang and Dewaele (2019) reported that the scale displayed high internal reliability (Cronbach’s ɑ value = .889). 3.3. Data collection Before collecting data, we obtained permission from the university to conduct the research. Then, three English language teachers briefly introduced the research Language learners’ emotion regulation and enjoyment in an online collaborative writing program 467 purpose to potential participants and invited them to participate during regular class time. To reduce students’ potential concerns that participation in the re- search might impact their course grades, the teachers explained that the data were collected solely for research purposes and were unrelated to students’ course scores. We sent consent forms via email to participants who showed in- terest in the research project to obtain their formal approval and consent. Data collection began in early January 2020 after the participants had completed all ten online collaborative English writing tasks in the winter semester of the 2019- 2020 academic year. First, two scales in the questionnaire, AIRE and FLES, were pilot tested with 37 students who were not included in the main study but were similar to the participants in terms of age, grade, major, and language profi- ciency. For AIRE, analysis of internal reliability indicated that Item 2 “I tried to act more flexible, open, and tolerant” needed to be deleted due to a low cor- rected item-total correlation (r = .13). After this item deletion, the resulting 11- item AIRE achieved a Cronbach’s ɑ value of .923 in the pilot test and .937 in the subsequent main study. For FLES, all ten items exhibited satisfactory correlations (r > .30) with the scale (Field, 2013). Cronbach’s ɑ value of FLES was .917 in the pilot test and .942 in the subsequent main study. Following the pilot test, a total of 345 questionnaires were distributed and completed online. Nine cases with missing values were deleted, which left 336 participants in the database. 3.4. Data analysis The data analysis proceeded in three steps. To investigate the major types of emotion regulation and the factor structure of enjoyment (RQ1), principal com- ponent analysis was first performed using SPSS 27 based on the data collected from 336 participants. Then, Pearson correlation analysis was conducted to of- fer an initial glimpse into the relations across different types of emotion regula- tion and enjoyment (RQ2). Based on Plonsky and Oswald’s (2014) recommen- dations, the strength of the correlation coefficients (r) was interpreted as small (r = .25), medium (r = .40), and large (r = .60). Finally, structural equation mod- eling (SEM) was further conducted using AMOS 26 to explore how different types of emotion regulation directly and indirectly affected enjoyment in online collaboration (RQ3). In the SEM analysis, multiple fit indices were considered to assess three optional models. These were the ratio of chi-square to degree of freedom (χ2 / df), the comparative fit index (CFI), the Tucker–Lewis index (TLI), the root mean square error of approximation (RMSEA), and the standardized root mean square residual (SRMR). Good fit thresholds for these indices are χ2 / df < 3.00, CFI > 0.90, TLI > 0.90, RMSEA < 0.08, and SRMR < 0.08 (Dagnall et al., 2018; Wan et al., 2021). For χ2 / df, RMSEA, and SRMR, the smaller value is assumed to be Zhipeng Zhang, Xuesong (Andy) Gao, Ting Liu, Chwee Beng Lee 468 the better model fit. For CFI and TLI, the greater value represents the better model fit. It should also be noted that, following Plonsky and Oswald (2014), the strength of the determination coefficients (r2) in the present study was consid- ered to be small (r2 = .0625), medium (r2 = .16), and large (r2 = .36). 4. Results 4.1. Major types of emotion regulation and factor structure of enjoyment To identify the appropriateness of the data for EFA, we first tested two basic assumptions of factor analysis: sampling adequacy and multivariate normality (Lattin et al., 2003). The KMO value of the data (N = 336) was .921, which was above the minimum acceptable level (.600), indicating that the sampling was sufficient (George & Mallery, 2019). The Bartlett’s Test of Sphericity obtained a value of c2 (210) = 5978.093, which was significant at the p < .001 level, indicat- ing that the data were multivariate normal and the correlations between the items were sufficient for factor analysis (George & Mallery, 2019). The subsequent principal component analysis extracted three factors with eigenvalues over Kaiser’s criterion of 1, explaining 76.88% of the total variance. To maximize the items’ factor loadings for a clearer interpretation of the extrac- tion results, varimax rotation was run to present the pattern of loadings (Wipu- lanusat et al., 2017). After factor rotation, we retained three factors that included items with factor loadings of 0.5 or greater, as 0.5 was perceived as a cut-off value indicating items’ significant interpretability of the related factor (Wipulanusat et al., 2017). Table 1 shows the items and their factor loadings related to each factor. As shown in Table 1, we named the factors to correspond with the items included in each factor. Factor 1 included items 3, 4, 5, 7, and 8. With “I” and “oth- ers” being the keywords, all these items were associated with the regulatory acts directed by one person toward other peers in groups, such as “I tried to explain to others that we needed to understand the differences in the group.” Therefore, factor 1 was labeled peer regulation. Factor 2 contained items 9, 10, 11, and 12. Starting with “as a group” and “we,” these items reflected the joint activities made by the group as a whole in supporting emotion regulation. Therefore, factor 2 was named group regulation. Factors 1 and 2 represented two major types of emotion regulation participants enacted during online collaborative language learning. Factor 3 received high positive loadings from items 13, 17, 19, 20, 21, and 22, highlighting the enjoyable atmosphere for online collaborative learning; for in- stance, “There was a good atmosphere” and “We laughed a lot in groups.” Con- sequently, factor 3 was named enjoyment of online collaboration.

Correlations between peer regulation, group regulation, and enjoyment of online collaboration Pearson correlation analysis was conducted among peer regulation, group regula- tion, and enjoyment of online collaboration to investigate relationships among these constructs. As displayed in Table 2, all of them were positively and significantly correlated with each other (ranging from r = .255 to .569; p < .001). According to Plonsky and Oswald (2014), these results represent medium effect sizes, as the var- iance accounted for ranged from 6.5% to 32.3%. The correlation between peer reg- ulation and group regulation was found to be the strongest (r = .569, representing a medium effect size, with 32.4% of the variance being explained). Both peer regu- lation and group regulation were positively linked to enjoyment of online collabo- ration. However, compared with peer regulation (r = .255, representing a medium effect size, with 6.5% of the variance being explained), group regulation (r = .492, representing a medium effect size, with 24.2% of the variance being explained) ex- hibited a stronger relationship with enjoyment of online collaboration.

EOC = enjoyment of online collaboration; ***p < .001. 4.3. Effects of peer regulation and group regulation on the enjoyment of online collaboration Three models, depicted in Figure 1, were established to investigate how peer and group regulation impacted enjoyment of online collaboration. As shown in Table 3, Model 3 was the best among the three models, as the fit indicators for this model (χ2 / df = 2.886; CFI = .960; TLI = .952; SRMR = .043; RMSEA = .075) were better generated than those for Model 1 (χ2 / df = 2.916; CFI = .960; TLI = .951; SRMR = .043; RMSEA = .076) and Model 2 (χ2 / df = 3.498; CFI = .947; TLI = .937; SRMR = .115; RMSEA = .086). The parameters of Model 3 are presented in Table 4. As shown in Table 4, peer regulation predicted group regulation significantly and positively (b = .567; p < .001), explaining 32.1% of its variance (effect size was medium). In addition, group regulation predicted enjoyment of online collaboration in a positive and significant way (b = .490; p < .001), explaining 24% of its variance (effect size was medium). Further, peer regulation exhibited an indirect effect on en- joyment of online collaboration. The results suggested there was a mediating effect of group regulation between peer regulation and enjoyment of online collaboration. Model 1 Language learners’ emotion regulation and enjoyment in an online collaborative writing program 471 Model 2 Model 3 Figure 1 Three models to be tested A bootstrapping procedure was conducted to evaluate the significance of peer regulation’s indirect effect on enjoyment of online collaboration. As shown in Table 5, with 95% confidence intervals, neither bias-corrected (.209 ~ .360) nor percentile confidence intervals (.205 ~ .359) included zero. This demon- strates that peer regulation exerted a significant indirect effect (Du Prel et al., 2009) on enjoyment of online collaboration. The standardized indirect effect co- efficient of peer regulation for enjoyment of online collaboration was .278, sig- naling a medium effect size by explaining 7.7% of the variance.

Discussion The purpose of RQ1 was to identify the primary types of emotion regulation and the unique factor structure underpinning enjoyment in the online collaborative EFL writing of Chinese students majoring in English. Through principal compo- nent analysis, this study identified two major types of emotion regulation in online collaborative language learning: peer regulation and group regulation. In line with the two types of emotion regulation, co-regulation and socially shared regulation, defined in previous studies (Järvenoja & Järvelä, 2009; Järvenoja et al., 2019; Järvenoja et al., 2013), the findings of the present study indicate that learners’ emotion regulation operates at individual and group levels in a collab- orative learning context. Peer regulation, the identified factor 1 of this study, was similar to co-regulation because it reflected individual learners’ attempts to affect others or their inclination to be affected by others. Group regulation was equivalent to socially shared regulation, as they contained the same items stressing the joint regulatory efforts of the group as an entity. However, self- regulation, a traditional type of emotion regulation Järvenoja and Järvelä (2009) observed in face-to-face collaborative settings, was not identified as a major type of emotion regulation in the online collaborative setting examined in this Language learners’ emotion regulation and enjoyment in an online collaborative writing program 473 study. This difference might have occurred because the implementation of emo- tion regulation depends on the situational context (Hadwin et al., 2018; Järve- noja et al., 2015). Due to the reduction of non-verbal cues, such as facial expres- sions and physical behaviors in online collaboration, learners might tend to spend more time and energy than they would in face-to-face situations regulat- ing each other’s emotional states and the group work instead of their own emo- tions (van der Meijden & Veenman, 2005). Further, both peer regulation and group regulation contained items that re- flected learners’ adoption of emotion regulation strategies originally used for self- regulation in previous studies (e.g., Bielak & Mystkowska-Wiertelak, 2020a; Gross, 1998). For example, cognitive change, an emotion regulation strategy to reassess the personal meanings of emotion-inducing situations, could be found in learners’ acceptance of individual differences in Item 7 (“I tried to explain to others that we needed to understand the differences in the group”) and Item 12 (“As a group, we accepted the differences within the group”). Situation modification, which entails the alteration of emotionally-charged situations, was also notable in learners’ modification of the way they collaborate in Item 5 (“I told the others we needed to be more flexible in order to find a compromise/solution to differences and con- flicts between us”) and Item 11 (“As a group, we decided that we had to sort out problems together in order to carry on working”). This result corroborates the previous finding that learners may enact various strategies originally developed to regulate themselves, such as change of cognitions and modification of the sit- uation, to regulate peers’ emotions and the group’s emotional climate in a collab- orative learning context (Bakhtiar et al., 2018; Järvenoja et al., 2019). Enjoyment of online collaboration, the enjoyment-related factor identified in this study, corresponded to FL enjoyment–Social (Dewaele & MacIntyre, 2016) and FL enjoyment–Atmosphere (Li et al., 2018) in previous studies conducted in classroom learning contexts. All these factors focused on the positive learning climate built up by interactions among learners. However, enjoyment of online collaboration specified the online collaborative setting of this study where the socioemotional atmosphere was strongly present (Linnenbrink-Garcia & Pekrun, 2011). The identification of this factor indicates that the enjoyment learners experienced during online collaboration was mostly linked to the social and emotional climate within their group. RQ2 concerned the relationships between peer regulation, group regulation, and enjoyment of online collaboration. The Pearson correlation analysis revealed medium positive correlations among these constructs. The results imply potentially reciprocal relations among two major types of emotion regulation and enjoyment. Learners’ enjoyment in online collaboration depended on not only their engage- ment in peer and group regulation but also perhaps the interactions between these two types of emotion regulation. In line with previous studies (Bakhtiar et al., 2018; Zhipeng Zhang, Xuesong (Andy) Gao, Ting Liu, Chwee Beng Lee 474 Järvenoja et al., 2019), this finding suggests that different types of emotion regula- tion, such as peer and group regulation, often emerge simultaneously and interact with each other to construct a positive social climate in groups. RQ3 pertained to direct and indirect influences of peer regulation and group regulation on enjoyment of online collaboration. The SEM analysis demonstrated that group regulation directly and positively affected enjoyment of online collaboration. The effect size was medium. This result strengthens the previous finding that group regulation is essential to creating and maintaining a positive group climate during collaboration (Mänty et al., 2020). Facing socio- emotional challenges, such as relational and communication problems, is a nat- ural part of collaboration process (Järvenoja et al., 2019). Therefore, group reg- ulation can help control the socioemotional atmosphere when challenging situ- ations arise in collaborative learning (Näykki et al., 2014). The study also highlighted an indirect medium-size effect of peer regulation on enjoyment of online collaboration, mediated by group regulation. This result sug- gests that peer-directed regulation contributed to enjoyment in online collabora- tion indirectly by boosting group-directed regulation. The facilitative role of peer regulation in group regulation supports the argument of Rogat and Adams-Wiggins (2015) and Hadwin et al. (2018) that consistent and productive regulation toward each other in a group enables the entire group’s shared regulation to function. 6. Limitations and implications The current study has several limitations. First, the participants were English major students recruited from a single university in China. Future studies should involve more participants from various academic levels and institutions to strengthen our findings on language learners’ emotion regulation and enjoy- ment. Second, the study focused on online collaborative learning via WeChat- enhanced group chat. Since different platforms may provide different af- fordances to language learners, it is also important to explore how language learners work together through various communication tools, such as Black- board or Skype. When using different communication tools, language learners might employ different patterns of emotion regulation to increase their enjoy- ment of collaborative learning (Kwon et al., 2014). Third, the cross-sectional na- ture of this study means it may not reflect the dynamic changes in learners’ emotion regulation, their enjoyment, or the relationship between these aspects. Future studies may adopt various techniques and instruments, such as idiody- namic approaches and interviews, to capture learners’ ongoing emotion regula- tion processes and their enjoyment experience within groups (Elahi Shirvan et al., 2020; Järvenoja et al., 2018). Language learners’ emotion regulation and enjoyment in an online collaborative writing program 475 Despite these limitations, the findings of the present study can serve as a basis for some theoretical and practical implications. On the theoretical level, the present investigation extends previous studies on language learners’ emo- tion regulation and enjoyment to an online collaborative language learning con- text. Within this context, we have identified peer regulation and group regula- tion, and their complex effects on learners’ enjoyment. The findings offer a novel understanding that different forms of regulation (i.e., peer-directed and group- directed regulation) interact in contributing to an enjoyable group atmosphere in online collaborative activities. On a practical level, the findings of the present study remind language teachers that the shared efforts of group members are needed to respond to group-wide emotions, as these efforts directly promote learners’ enjoyment. Thus, we propose that teachers should create opportunities to raise learners’ awareness of group regulation. For example, via learning analytics, teachers may capture log data from learners’ group regulation processes (Gašević et al., 2016). These data could allow teachers to provide personalized feedback for groups, which would enable them to understand the importance of group reg- ulation in face-to-face or online collaborative learning (Malmberg et al., 2017). Further, the study indicates that the importance of peer regulation, as another important type of emotion regulation influencing enjoyment indirectly through group regulation, should not be downplayed in language learning contexts. A positive collaborative climate requires peer-directed regulation to lay the groundwork for group-directed regulation. Therefore, we suggest language teachers, as more capable peers of learners in collaborative groups or class- rooms, employ appropriate strategies to guide or support learners’ emotional states. The strategies (e.g., cognitive change and situation modification) learn- ers used in this study could be a good choice. For instance, in the study of Bielak and Mystkowska-Wiertelak (2020b), language teachers purposefully reminded learners to accept the interpersonal differences in writing pace and strategy use. 7. Conclusion This study has explored how English language learners regulate their emotions individually and collectively to increase their enjoyment during online collabo- rative learning. The findings suggest that an enjoyable collaborative atmosphere is possible when learners take on individual responsibility to manage the emo- tions experienced within groups and maintain their shared responsibility to overcome challenges (Bakhtiar et al., 2018). More importantly, the study illuminates both direct and indirect effects of different emotion regulation types on FL enjoyment in online collaboration. Zhipeng Zhang, Xuesong (Andy) Gao, Ting Liu, Chwee Beng Lee 476 Group regulation was highlighted as a direct influencing factor on enjoyment, mediating the effect of peer regulation. This finding further enriches our under- standing of the complex interaction between different types of emotion regula- tion and positive emotions (FL enjoyment in this study). While such findings are enlightening, they provide only another piece of a very complex puzzle of how language learners regulate their emotions to enjoy the online collaborative learning process. Therefore, further research is needed to gain more insights into this area. Given the complexity of relationships between emotion regula- tion and enjoyment in online collaboration, it is advisable to conduct in-depth case studies on the online interactions of diverse collaborative groups using video observation and stimulated recall interviews. Doing so would illuminate how different types of emotion regulation interact to enhance enjoyment. It would also make sense to include more emotional states, such as anxiety and boredom, to examine how these relate to different types of emotion regulation in online collaborative language learning. Understanding the interplay between emotional experiences and emotion regulation activities during language learn- ers’ online collaboration is vital for illustrating how they can transform their online interactions into pleasant and successful ones.
