Abstract:  Numerous studies suggest professional development to improve educators’ 

attitudes toward inclusive education. However, not all professional development seems to 

be effective in boosting participants’ attitudes. This current study is aimed to explore the 

effectiveness of professional development in inclusive education, especially for 

kindergarten principals in Indonesia. By conducting a 10-day professional development 

(n=60), the attitudes toward inclusive education of the participants were measured before 

and after the professional development using ITAIE (The Indonesian Teachers' Attitudes 

toward Inclusive Education). A paired T-Test was applied to find the differences in 

principals’ attitudes toward inclusive education before and after the professional 

development. The finding revealed no significant improvement in kindergarten principals’ 

attitudes toward inclusive education after joining the traditional way of professional 

development.

INTRODUCTION  

Many scholars reveal that teachers’ attitudes towards inclusive education determine the 

successful implementation (Avramidis & Kalyva, 2007; Barnes & Gaines, 2015; Elisa & 

Wrastari, 2013). In addition, teachers' attitudes towards inclusive education greatly influence 

the learning environment in inclusive schools (Monsen et al., 2014). Barnes and Gaines (2015) 

believed teachers with positive attitudes towards inclusive education could create a good 

school atmosphere to bring positive student achievements. . 

One of the ways to gain the positive attitudes teachers need to attend professional 

development in inclusive education. In a study by Avramidis and Kalyva (2007), 60% of the 

135 participants believed their attitudes would be affected by their knowledge. One-third said 

they could get more knowledge through professional development. In addition, Prinsloo 

(2006) believed that professional development was a key factor in positively impacting 

teachers' attitudes toward inclusive education. 

In fact, principals' attitudes and knowledge towards inclusive education still become 

barriers to actualizing inclusive education as they lack professional development. Meanwhile, 

Slee (2010) points out that professional development programs keep struggling to equip 

teachers to implement inclusive education. Unfortunately, most studies reveal that 'sit and get' 

professional development has had fewer impacts on improving educators' competencies 

(McLeskey & Waldron, 2002; Nishimura, 2014; Tate, 2012). Therefore, the current study will 

explore the effectiveness of the traditional way of professional development to improve 

kindergarten principals’ attitudes toward inclusive education.

METHOD  
The current study used a quasi-experiment comparison group design by applying a traditional 

way of professional development as the intervention. Upon obtaining ethical approval, 60 

Indonesian kindergarten principals were asked to join the conventional professional 

development for ten days. Some participants represented each island to join the professional 

development. Due to the pandemic situation of COVID-19, the class was held online with 60 

participants. 

The ITAIE scale – The Indonesian Teachers' Attitudes toward Inclusive Education scale 

developed by Ediyanto (2020) was applied to measure the principals' attitudes toward 

inclusive education before and after the treatment. The instrument contains a six-point Likert 

scale ranging from Strongly Disagree (1), Disagree (2), Neutral (3), Agree (4), to Strongly 

Agree (5). For the analysis, the Paired T-Test was applied to measure the significant difference 

between pre and after the professional development. 

 

RESULT AND DISCUSSION 

Result(S) 

Respondent background 

In this current study, kindergarten principals joined the traditional professional development. 

The participants were asked to complete a survey about their attitudes toward inclusive 

education before and after the professional development was conducted. To indicate the level 

of the attitudes, the range of the mean will be as follows: 

 A mean score of more than 3.5 (M > 3.5) will be considered that kindergarten principals 
have a high positive attitude toward inclusive education at kindergartens, 

 A mean score between 1.3 and 3.5 (1.3 ≤ M ≤ 3.5) will indicate a moderate attitude, 

 A mean score lower than 1.3 (M < 1.3) will show the negative attitude of kindergarten 
principals towards implementing inclusive education at kindergartens. 

 

From the quantitative data analysis in the control class, the mean score of principals’ 

attitudes toward inclusive education before the professional development was 3.0 (see Table 

1), between 1.3 and 3.5 (1.3 < M < 3.5). It indicated that participants’ attitudes towards 

inclusive education were moderate attitude. After the professional development, the attitudes 

were measured again. There was a slight improvement; the mean was 3.1 (Table 2), but still 

moderate attitudes.

The Paired T-Test analysis was applied to get more accurate data about the difference 

Paired Sample T-test was used to determine whether there are differences in kindergarten 

principals’ attitudes before and after the conventional professional development in inclusive 

education. 

The decision-making guideline in paired sample t-test was based on the significance 

value.  

 If the probability or significance value (sig. 2-tailed) is less than 0.05 (<0.05), then there 
is a significant difference between principals’ attitudes before and after the 

professional development in inclusive education  

 Conversely, if the value of probability or sig. (2-tailed) is higher than 0.05 (> 0.05), then 
it can be concluded that there is no significant difference between principals’ attitudes 

before and after the professional development in inclusive education  

 

The Paired T-Test analysis found that the sig (2-tailed) value was 0.144 (Table 2). This 

value was more than 0.05. Since the sig. (2-tailed) was higher than 0.05 (> 0.05), so it was 

concluded that there was no significant difference between principals’ attitudes before and 

after the professional development. In other words, the traditional professional development 

did not successfully improve principals’ attitudes toward inclusive education.

Discussion(s) 

The traditional professional development in this current study did not apply any 

combination of professional development except the “sit and watch” method. As predicted, it 

did not improve teachers’ attitudes towards inclusive education.  Most studies claimed that the 

failure of traditional professional development to improve teachers’ competencies was due to 

its top-down structure, one-size-fits-all nature, and lack of continuous follow-up and support 

(Shurr et al., 2014; Utami & Prestridge, 2018; Visser et al., 2014).  

This finding reinforced some other studies about traditional professional development's 

failure to boost teachers’ attitudes and competencies, for example, a study by Reina et al. 

(2019) and Ediyanto et al. (2020). They found that the traditional professional development 

failed to boost 40 Spanish Physical Education Teachers’ (PET) attitudes towards inclusive 

education. This result was also in line with the study by Sykes (1996). He said that a 

traditional professional development where teachers do one-shot training was ineffective in 

developing their competencies. Artman et al. (2020) also argued that traditional professional 

development failed to meet teachers’ needs. As a result, the students’ achievements were also 

hard to gain.  

However, some studies mentioned different results regarding the improvement of attitudes 

towards inclusive education after professional development. Many studies mentioned that 

professional development could boost teachers’ attitudes toward inclusive education, such as 

Ediyanto (2020), Kuyini and Desai (2008), Lambe (2007), and Male (2011). Male (2011) 

revealed that forty-eight teachers, who were enrolled in a master's program in Special and 

Inclusive Education, indicated having more positive attitudes at the end of the professional 

development compared with at the beginning for four categories of inclusion, namely 

physical/sensory; social; academic; and behavioral.

CONCLUSSION 

A positive attitude toward inclusive education is a key element in implementing inclusion. 

One of the ways for educators to achieve it is by joining professional development. However, 

not every professional development has successfully improved educators’ attitudes toward 

inclusion. This current study revealed that the traditional professional development in 

inclusive education had failed to improve kindergarten principals’ attitudes toward inclusion. 

The principal’s attitudes remained moderate before and after the professional development. 

However, this finding could not be generalized in other areas of education except in a 

kindergarten setting with a limited number of participants. Future studies with more 

participants and comparison control and experiment group would give comprehensive results.
