A Problem-Based Learning (PBL) and Teaching Model using a Cloud-Based Constructivist Learning Environment to Enhance Thai Undergraduate Creative Thinking and Digital Media Skills https://doi.org/10.3991/ijim.v15i22.24963 Parawee Srikan, Paitoon Pimdee(), Punnee Leekitchwatana, Akan Narabin King Mongkut’s Institute of Technology Ladkrabang (KMITL), Bangkok, Thailand paitoon.pi@kmitl.ac.th Abstract—The objective of this research was to develop a Problem-Based Learning (PBL) Model which used a cloud-based constructivist learning environ- ment to enhance Thai undergraduate creative thinking and digital media skills. Initially using a mixed-methods approach, a five-step model was conceptual- ized. Thereafter, a panel of five academic experts gave input into the model’s design from which the model was expanded to include six related learning envi- ronments. The instrument used in the research was a problem-based assessment form. Data collection was carried out utilizing group chats and analyzed using descriptive statistics including the mean and standard deviation. The results of the study revealed that the initial model contained five steps including (1) problem identification, (2) problem analysis, (3) research, (4) presentations, and (5) sum- mary and evaluation, which is integrated into the model’s additional six learning environment elements. These six learning environments were (1) problem-based, (2) resources, (3) cognitive tools, (4) collaboration, (5) scaffolding, and finally, (6) coaching. When applying the proposed model and related environments, there was a consensus from the experts that the model had excellent suitability and can be used as a model for teaching and learning at the bachelor’s degree level. Keywords—computational thinking, critical thinking, internet, Thailand 1 Introduction Today, student university education is being transformed due to digital technologies being integrated into the classroom environment [1], where the importance of each teacher’s learning activities is of crucial importance in assisting students in build- ing their comprehension and learning stimulation. Also, student cooperative class- room activities are the driving force for self-knowledge creation, which has its roots in constructivist-inspired thinking [2], where knowledge is acquired through content involvement instead of imitation or repetition [3]. This is consistent with early research from Papert on the concept of computational thinking (CT) in which he considered CT to be a result of his constructionist educational approach, where affective and social 68 http://www.i-jim.org https://doi.org/10.3991/ijim.v15i22.24963 mailto:paitoon.pi@kmitl.ac.th Paper—A Problem-Based Learning (PBL) and Teaching Model using a Cloud-Based Constructivist... dimensions are as crucial as the technical content of the lesson [4]. Papert’s CT also stressed the computer’s importance as a powerful meta-tool for “making the abstract concrete” as well as the assertion that these CT skills were transferable to other disci- plines. Therefore, CT promotion today is potentially possible through the use of various digitally-based platforms and environments such as flipped classrooms and blended e-learning models, using the integration of online learning and digital technology devices such as smartphones, tablets, and learning management systems (LMSs) such as Moodle and Schoology [5]–[8] and the Internet of Things (IoT) [9]. Therefore, the use of digitally based learning platforms and models such as flipped classrooms and blended learning using the Internet cloud has become an educa- tor’s way of embracing 21st—Century technological digital innovation in which student-centered assigned lectures outside of class is now possible [9], [10]–[12]. These new digitally based, Internet cloud-hosted classroom environments also fuel the need for information, communications, and technology (ICT) development mandated under ICT objectives laid out by Thailand’s 12th National Economic and Social Devel- opment Plan [13] and precepts outlined under Thailand’s 4.0 goals for digitally based knowledge-workers. When combined with student preparation outside the classroom, in-classroom ana- lytical problem-solving activities, and complex problem-based learning (PBL) pro- cesses based on computer science techniques, the authors believe that creative thinking and critical thinking skills can be increased. However, educators must be willing to encourage learners to engage during learning sessions and assist in the process of solv- ing teacher-led problem-based learning (PBL) exercises [14]. This can then lead to advanced thinking process development, learning enjoyment, and higher-order think- ing skills (HOTS). It has also been added that that HOTS uses concept formation, criti- cal thinking, creativity and brainstorming, problem-solving, mental representation, rule use, reasoning, and thinking logically [15]. This then can lead to a student’s ability to understand complex problems by logically connecting different sets of information, which can then provide various perspectives on problem-solving. Therefore, 21st Cen- tury educators need to integrate ICT skills, digital literacy skills, knowledge, and atti- tudes [6], [16] into their IoT classrooms [17]. Furthermore, research has contended that there is a growing need to integrate con- structivist environments into pedagogical practices [18] in which students are sup- ported in building and reflecting on their knowledge from previous critical thinking teacher-guided exercises. Therefore, in this new and evolving world of digital-based devices connected to cloud-based learning platforms and resources, collaboration and constructivism become tools in new knowledge creation [19]. Therefore, in learning activities, learners are independent and have their own goals to create a body of knowledge on their own and apply this knowledge to create innova- tion within society [20]. Moreover, creativity is a special process of the human brain, which makes it possible to see new possibilities and alternatives. Creativity and crit- ical thinking skills also allow members of society to face their fears, hardships and solve challenging problems. Moreover, change is accelerating and online education is a way to meet this change head-on. Also, in a Covid-19 pandemic world, education has been forced to move online. However, the good news according to the United Nations iJIM ‒ Vol. 15, No. 22, 2021 69 Paper—A Problem-Based Learning (PBL) and Teaching Model using a Cloud-Based Constructivist... Children’s Fund (UNICEF) in a 2017 report is that the most Internet-connected age group in the world is from 15 to 24, with 71% being connected online as compared to the global average of 48% [21]. Therefore, mobile digital devices connected to cloud- based platforms can create opportunities for collaboration and transform the way we live, relax, spend our free time, and even have fun. Creative innovation is also being used to improve the quality of life in preparing young people to enter the real world, who can deal with difficulties, challenges, and solve real-world problems. 2 Supporting literature The following sections are a brief overview in support of the authors’ development of the study’s proposed conceptual learning model. 2.1 Problem-based learning (PBL) In the process of problem-solving, educators make use of learning models to actively involve and stimulate student thinking skills [22], [23]. In recent years more and more teachers have integrated PBL concepts into their classrooms as PBL actively involves students in investigating and participating with authentic and meaningful problems whose result is the creation of knowledge and concepts from each discipline studied [24]. Other researchers have also reported on the positive outcomes (motivation and digital literacy increases) when PBL is integrated with some form of online learning [14], [25], [26]. Moreover, when a blended-PBL classroom is created, effectiveness is even further enhanced over conventional PBLs [27] and is effective in increasing the student’s learning activities motivation [28]. Finally, numerous studies have reported that when digital devices are integrated with PBL activities, critical thinking and cre- ativity skills are increased [29]. Therefore, PBL aims to manage learning in such a way that learners have the most opportunity to learn by themselves through study, research, experimentation, practice, thinking, problem-solving, and creativity [30]. Also, PBL is an appropriate teaching method for developing learners in the 21st Century because it is a teaching method that uses problems or situations as a starting point for learning and the seeking of knowl- edge [31], which then can potentially develop problem-solving skills, self-learning and teamwork [32]. In this environment, students can create new knowledge by applying real-world problems as a learning context to develop skills in critical thinking and problem solving [30], as well as gaining knowledge based on science in the field of study. Since PBL is a teaching technique that encourages students to practice and solve problems on their own, student skills in logical thinking and critical thinking, analytical thinking, syn- thetic thinking, and creative thinking are enhanced. Other studies have also suggested that PBL learning enhances learner hypothesis and reasoning skills, self-study skill development, and teamwork and collaboration effectiveness [32]. Therefore ‘chalk and talk’ dies and classroom environments become livelier, promoting cooperation and col- laboration between departments or agencies. 70 http://www.i-jim.org Paper—A Problem-Based Learning (PBL) and Teaching Model using a Cloud-Based Constructivist... 2.2 Cloud-based constructivist learning environment (CBCLE) Learning based on constructivist theory is a process that takes place within the learner with each individual creating knowledge from the relationship between what they see and their past knowledge and previous understandings [24]. In this process, individuals try to use their understanding of events and phenomena they see to create or adjust their existing cognitive structures to the new environment. Within the digital world, it has been suggested that a well-designed mobile game that requires player agency and meaning is an excellent example of constructivist learning [33]–[35]. Moreover, to achieve a balance between one’s self and the learning process, constructivist theory encourages children to do activities according to their interests, while taking into account the important basic elements of their interest, play, experimen- tation, and cooperation. Also, constructivist or student-centered learning asks students questions, after which the learners are divided into small groups who work together to discover one or more solutions [36]. Also, the relationship between the teacher and the learner should be cooperative rather than compulsory or control-driven [37]. Also, although digital learning tools and learning applications can run on a single computer or a network of computers not attached to the Internet, this is becoming rarer as educational institutions equip their faculties to assess applications (apps) outside their physical environment. Today, a frequently used term to describe the processes, tools, and locations of these apps is the word ‘cloud’ which is nothing more than a metaphor for the Internet. Although it can be debated as to the term’s origination, some might sug- gest it comes from the design element used for the Internet in network design software (a cloud) or maybe even further back as the word used by Telco operators to describe their network facilities outside their switch rooms. Either way, today the ‘cloud’ is a critical element in serving up countless educational tools from around the world. When educators discuss flipped or blended-learning classrooms or Khan Academy, it is necessary to talk about the application servers supporting the learning environment which run in the cloud such as Moodle®, Schoology®, or the vast array of Google apps such as Google for Education®. It is also impossible to talk about Social Media such as Facebook® or Line® without also talking about access to their servers in the cloud. Therefore, the adoption of cloud technology as a teaching tool is very important in promoting new ideas for learners. One great advantage often mentioned in Flipped classrooms is the idea that education can take place anytime and anywhere. Beyond the obvious advantage of having an application hosted by a service provider that has the infrastructure to assure maximum connectivity and bandwidth around the clock, there are also other significant cloud computing advantages such as unlimited network stor- age, backup, redundancy, ever-increasing processing power, management, and security. Significant ICT and personnel costs are also offloaded in most cases from the institution to the vendor in the cloud. This by itself is a powerful motivational aspect for using cloud-based applications. 2.3 Creative thinking In the age of Information, creativity has increasingly risen in value as a crucial capa- bility [38] which has also had a shift of emphasis to problem-solving. Therefore, today iJIM ‒ Vol. 15, No. 22, 2021 71 Paper—A Problem-Based Learning (PBL) and Teaching Model using a Cloud-Based Constructivist... scholars and educators take a cognitive approach that focuses on thinking abilities as the basis of creative work. Additionally, creativity as a concept has been used over time in a very broad sense. However, a fair definition of creative would be having the capacity to come up with “original, inventive and novel ideas” [39, p. 6]. Creativity is also the foundation for innovation and discovery, which are characterized by the two qualities of usefulness and novelty [40]. 2.4 Literature review summary Therefore, the authors believe that PBL and teaching promote creativity, especially when implemented in the cloud using a constructivist learning environment. How- ever, the process entails a variety of teaching concepts and theories which emphasize learners practicing and performing tasks from learning activities. Also, there is a vari- ety of learning resources and approaches to problem-solving that differ according to interests which require behavior and thought development through a student-centered learning process. Learners can create works of knowledge, experiences, activities, or exchange knowledge with friends, teachers, experts, as well as cooperate between teachers and learners. Therefore, the following section details the methods, results, and discussion of the expert input and evolution of the study’s models for use by Thai undergraduate students. 2.5 Objectives of the research To develop and assess the appropriateness of a PBL and teaching model using a cloud-based constructivist learning environment (CBCLE) to enhance Thai undergrad- uate creative thinking and digital media skills. 3 Method of model development and assessment This study used mixed research methods to develop a pattern [41] by combing ele- ments of qualitative and quantitative research practices [42]. Initially, the qualitative research was reviewed, synthesized, and analyzed to pro- duce a PBL learning model for creative and critical thinking enhancement using five primary steps. This was followed by a second qualitative analysis in which six steps were determined to be potentially useful in a blended learning environment. Finally, a quantitative analysis was conducted of the proposed model by a panel of seven experts. 3.1 The proposed PPRPS model’s five steps The PBL and teaching model using a cloud-based constructivist learning environ- ment (CBCLE) to enhance Thai undergraduate creative thinking and digital media skills was determined to consist of five steps (Figure 1). These were (1) problem identification, (2), problem analysis, (3) research, (4) presentations, and (5) summary and evaluation. Therefore, the authors identified the initial proposed model as the “PPRPS Model”. 72 http://www.i-jim.org Paper—A Problem-Based Learning (PBL) and Teaching Model using a Cloud-Based Constructivist... Step 1: Problem identification The teacher plays a role in presenting the problem, issue, and case study related to the lesson to stimulate interest, from which teachers and students work together to define problems or issues that need to be solved. Groups are organized into 3 - 6 students each based on assorted knowledge from the results of pre-study exams. Thereafter, learners collaborate in determining the problem or issue that needs to be solved and share the responsibility to find a solution within the group. Emphasis is placed on real roles such as group leader, data aggregator, and presenter through communication tools including Google Meet® and Line® social media platforms. Collaboration tools include Google Drive®, Google Docs®, and Google Calendar®. Therefore, participation in a co-learner community and on broader scale participation in a community of practitioners is char- acterized as socialization. This therefore can be extended into the broader social and cultural rules and conventions that are common to all global communities [43]. Step 2: Problem analysis Students are given responsibility for analyzing, isolating, and discussing the root causes of the assigned problems to determine the issues or learning objectives, as well as conducting further research to gain more subject knowledge. The teacher’s role is to introduce the learning environment and collaborative tools resources such as Google Drive®, Google Docs®, and Google Calendar®. Step 3: Research Each learner is responsible to research their new knowledge from the learning envi- ronment, including resources, cognitive tools, and support bases to bring the information to discuss, analyze, and synthesize per the objectives. During this process, a multitude of tools can be used to facilitate the five proposed steps. These include learning man- agement systems (LMS) tools such as Google Classroom®, Moodle®, or Schoology®, communication and social media tools such as Google Meet® and Line®, collaboration tools such as Google Drive®, Google Docs®, Google Slides®, and Google Calendar®, and finally, creative tools such as Google Drawings® and Canva®, among others. Stage 4: Presentations Numerous cloud-based products are also available to help students present their work including creativity tools such as Illustrator®, Procreate®, Google Drawings® or Canva®, communication tools such as Google Meet®, Google®, and Line®, and presenta- tion tools such as Google Slides®, YouTube®, and PowToon®. Students can make presen- tations through captions, pictures, or digital media. Instructors can create stimulating questions to show the relationship of the information to check the consistency of the work produced with the objectives. Step 5: Summary and evaluation In the final summary and evaluation process step learners come together to summa- rize new ideas or knowledge from the produced work. Although most would consider the above applications as productivity tools, in reality, these tools become a student’s intellectual partner which enhances their cognitive powers during thinking, prob- lem-solving, and learning [44], [45]. iJIM ‒ Vol. 15, No. 22, 2021 73 Paper—A Problem-Based Learning (PBL) and Teaching Model using a Cloud-Based Constructivist... Finally, the teacher assesses the learning development of learners by assessing the results produced. The students assess themselves and assess the performance of the group members, which leads to the final post-test using learner assessment tools based on Google Form®, Google Sheets®, or Rubistar®. Fig. 1. The proposed PPRPS model 3.2 PBL model’s steps From the second phase of the qualitative analysis, the authors determined that six ele- ments were important in a PBL model which utilized a cloud-based constructivist learn- ing environment (CBCLE) to enhance Thai undergraduate creative thinking and digital media skills (Figure 2). These included (1) problem-based, (2) resources, (3) cognitive tools, (4) collaboration, (5) scaffolding, and finally, (6) coaching [35], [46]. 3.3 Experts’ model assessment After the development of the study’s initial proposed PPRPS Model, seven experts with PhDs were invited to assist with the assessment of the model. Each academic had expertise in some aspect of teaching-learning styles, innovation, creativity, computer education, technology, educational programs, or research. From the panel of experts’ input, the researchers were asked to add to the model six learning environments (Figure 2). The final model’s conceptual framework was consistent and well supported by research from other scholars in Thailand and around the world [35], [46], [47]. 74 http://www.i-jim.org Paper—A Problem-Based Learning (PBL) and Teaching Model using a Cloud-Based Constructivist... Fig. 2. The proposed PPRPS model in a CBCLE and the six related learning environments 3.4 Experts’ quantitative model assessment Finally, a ‘suitability assessment form’ was given to each of the seven experts to assess their opinions concerning the final model’s overall suitability, benefits, feasibil- ity, and accuracy [48]. Thereafter, descriptive analysis was undertaken on the five-level agreement scale using both the mean and standard deviation (S.D.). 4 Results and discussion 4.1 Experts’ descriptive analysis results from the final model’s suitability assessment The descriptive analysis of the experts’ opinions concerning the final model’s overall suitability, benefits, feasibility, and accuracy was undertaken using both the mean and standard deviation (S.D.), with the model demonstrating excellent suitability according to the experts (Mean = 4.53, S.D. = 0.50) (Table 1). Table 1. Experts input concerning the PPRPS model’s suitability assessment Assessment Item Experts (n = 7) Suitability Level Mean S.D. Suitability standard 4.56 0.50 Excellent suitability Benefits standard 4.57 0.49 Excellent suitability Feasibility standard 4.49 0.50 Appropriate suitability Accuracy standard 4.48 0.50 Appropriate suitability Total 4.53 0.50 Excellent suitability iJIM ‒ Vol. 15, No. 22, 2021 75 Paper—A Problem-Based Learning (PBL) and Teaching Model using a Cloud-Based Constructivist... The PBL and teaching model using a cloud-based constructivist learning environ- ment (CBCLE) to enhance Thai undergraduate creative thinking and digital media skills was presented to a panel of seven experts from which the initial model was assessed. Thereafter, further dialog determined the need to add six learning environments to the model. These six learning environments were labeled (1) problem-based, (2) resources, (3) cognitive tools, (4) collaboration, (5) scaffolding, and finally, (6) coaching. These learning environments are also very similar to a study in which a CBCLE use for enhancing Thai undergraduate critical thinking skills included (1) problem base, (2) resources, (3) collaboration and coaching, (4) critical thinking lab, (5) scaffolding, and (6) cognitive tools [46]. Therefore, this allows learners to choose a learning envi- ronment that is most suitable for their problem situation. In addition, both students and teachers have cloud technology to help integrate and manage the various proposed learning environments. 4.2 Problem-based environment In the study’s revised final model design, both the assembled experts and supporting studies established the use of problem-based learning and teaching as the foundation and first step of the learning model for an effective CBCLE in enhancing Thai under- graduate creativity and digital media skills [35], [46]. 4.3 Resources environment Secondly, resources were determined to be the next key step in the process. Con- cerning this aspect of the model, the authors chose to define resources as ‘digital’ tools and platforms. As such, digital resources have limitations due to cost, location, avail- ability, and user knowledge. Resources can entail a learner’s smartphone, the teacher’s LMS such as Schoology, the amount of Internet bandwidth, or availability to the cloud- based application such as Line. This is consistent with similar studies in which constructivist learning environments were discussed and also defined resources as being based on the organization of infor- mation for multimedia design presentations [34]. Also, resources in another study were defined as a student’s use of animation, visual and audio resources [35]. 4.4 Cognitive tools environment Thirdly, cognitive tools were determined to play a central role in the model’s suc- cessful use and outcome with significant support coming from numerous scholars, old and new. A major reason today for this is the acceptance that application software is a tool that assists with the generation of cognitive skills such as problem-solving and critical thinking [44]–[46]. Moreover, databases and related applications can be thought of as MindTools which help learners integrate and interrelate discrete bits of content, making them more mean- ingful and more memorable [43]. By the use of these MindTools, learners engage in critical thinking and deeper thinking [49], [50]. In this situation, ICT applications are 76 http://www.i-jim.org Paper—A Problem-Based Learning (PBL) and Teaching Model using a Cloud-Based Constructivist... referred to as cognitive technologies [51], technologies of the mind [52], cognitive tools [44], [45] or MindTools [53], [54]. 4.5 Collaboration environment The next step within the proposed model is a collaboration which once again finds significant support in the global literature for successful student learning and creativ- ity. This is consistent with research in the USA in which the authors stated that social media’s ability to create opportunities for interaction allows the application of technol- ogy into social constructivist learning contexts in meaningful and innovative ways [55]. 4.6 Scaffolding environment Scaffolding was added to the final model by the panel of experts due to its impor- tance in a mobile learning environment (MLE). This is supported by Vygotsky whose scaffolding concept describes how learners in a social context can be provided indi- vidualized and just enough help and guidance from its use [56]. This is consistent with studies in Turkey in which the researchers identified four significant elements of scaf- folding in an MLE. These included the device type, provisioning source, implementa- tion timing, and the strategies in which it is used [57]. It was also determined that an MLE increased student interest and motivation. Furthermore, from the four primary types of scaffolding identified (social, instructional, managerial, and technical) indi- cated in the study, participants most frequently used Facebook®, then Twitter®, Google Calendar® and Diigo® for social scaffolding. Twitter® and Google Calendar® were most often preferred for managerial scaffolding, while Diigo® was most often preferred for instructional scaffolding. 4.7 Coaching environment Finally, collaboration, coaching, and cognitive tools are used for the collaborative learning process [43]. The concept of Cognitive CoachingSM is one that was initially developed for the support of teachers in which confidential, non-judgmental relation- ships between teachers and their coaches are established [58]. Thereafter, the relation- ship is based on authenticity, honesty, respect, and empathy, with each coach working to empower each teacher to be self-sufficient [59]. 5 Summary Therefore, according to UNESCO, when we examine contemporary constructivist learning, it is important to consider contemporary digital media [60]. Moreover, learn- ing with mobile devices and their use in a PBL environment as a cognitive tool pro- motes higher-order thinking skills (HOTS) [38], [61]. In Thailand, it has been reported that one of the most important projects for educators is to develop student-centered approaches to learning. Thus, the outcome hoped for will be an elevation of student achievement, development of 21st Century skills, and the iJIM ‒ Vol. 15, No. 22, 2021 77 Paper—A Problem-Based Learning (PBL) and Teaching Model using a Cloud-Based Constructivist... encouragement of students to be good Thai citizens with good morals and ethics [37]. Furthermore in Thailand, the Office of the Basic Education Commission (OBEC) was tasked to assess achievement and propose new teaching and support methods including coaching, peer coaching, and mentoring [62]. Within these contexts, the study chose problem-based learning (PBL) and teaching as its foundation for the model, which is a learning process that works towards prob- lem-understanding and problem-resolution [37]. Thus, educators should use problems to encourage students to explore knowledge and solve problems. PBL is a learner-cen- tered pedagogical approach that allows learners to work collaboratively with others on complex problems. Learners are also taught how to work independently to find solutions to group problems [63], which inspires critical thinking, higher performance, good decision making, and the willingness to engage in teamwork. Furthermore, other research has suggested that problem-based learning manage- ment (PBLM) is a process of design, implementation, and assessment steps [64] and suggest there are six steps in PBLM which include (1) Identify outcomes/assessments, (2) Design the scenario, (3) Introduce PBL, (4) Research, (5) Product performance, and finally, the (6) Assessment. 6 Conclusion The study initially set out to determine which aspects had a significant potential impact on the development of a problem-based learning and teaching model which made use of a cloud-based constructivist learning environment (CBCLE) to enhance Thai undergraduate creative thinking and digital media skills. From this phase of the research, it was determined that five elements had the best fit. These included (1) problem identification, (2), problem analysis, (3) research information, (4) pre- sentations, and (5) summary and evaluation. Thereafter, an analysis of the model was performed by a panel of seven experts who added that such a model should also include six additional learning environments. These learning environments included (1) problem-based, (2) resources, (3) cognitive tools, (4) collaboration, (5) scaffolding, and finally, (6) coaching. Finally, the final proposed learning model is well supported by similar studies globally. The study contributes to the literature as it details the tools educators should use in their learning environments to activate student learning creativ- ity and enhance digital media skills. 7 References [1] R.
