This study examined the effects of Global Korean Science Program (GKSP) on 608 Indonesian middle school students’ attitudes towards science. Their science attitudes were assessed before and after the programme with Behaviour, Related Attitudes, and Intentions towards Science (BRAINS) survey. We also collected students’ responses to an open-ended programme evaluation. The repeated-measures ANOVA was performed to compare students’ attitudes before and after the programme by including gender effect, followed by clustering analysis and magnitude coding to analyse open-ended programme evaluation data. Results showed that GKSP improved students’ behavioural and normative beliefs, suggesting that the programme had positive impacts on students’ beliefs about the importance of science in daily life. The decline in students’ control belief towards science after the programme indicates the possibility of science contents delivered in programme being more difficult than in the typical Indonesian science curriculum. Additionally, we found a significant gender effect on intention and normative dimensions. Furthermore, clustering analysis classified students into three groups; small changes (62%), increase trend (29%), and decrease trend (9%) indicating that most students participating in the study experienced a small science attitudes shift.}, journal={INTERNATIONAL JOURNAL OF SCIENCE EDUCATION}, author={Rusmana, Ai Nurlaelasari and Sya'bandari, Yustika and Aini, Rahmi Qurota and Rachmatullah, Arif and Ha, Minsu}, year={2021}, month={Jun} }

This study also examined the effects of prior experience and gender on CS learning and monitoring accuracy measured with sensitivity (proportion of confidence in correct answers) and specificity (proportion of uncertainty in incorrect answers). A total of 255 middle school students participated in this study. A one-group pretest-posttest design was used, and the data were analyzed using multilevel modeling and repeated-measures correlation tests. The results show a non-significant interaction effect of prior experience and gender on students' CS learning and monitoring accuracy. We found that gender significantly interacted with students' CS learning and monitoring accuracy, primarily specificity. In particular, UMC progression was able to reduce the gender gap in CS performance, and improved male monitoring accuracy. The results also showed a significant positive correlation between students' CS performance and sensitivity, and negative correlation with specificity. We discuss the results around the potential advantage of using a UMC progression strategy to reduce gender gaps in CS education, as well as the extent to which UMC can facilitate better instructional environments for serving students with a range of prior experiences.}, journal={LEARNING AND INDIVIDUAL DIFFERENCES}, author={Rachmatullah, Arif and Mayhorn, Christopher B. and Wiebe, Eric N.}, year={2021}, month={Feb} }

Method: Data from 493 elderly individuals (287 Chinese and 206 Korean) were used to examine the revised UCLA loneliness scale. The Research model based on item response theory (IRT) was used to test dimensionality, reliability, and item fit. The hybrid ordinal logistic regression-IRT test was used to evaluate DIF. Results: Item separation reliability, person reliability, and Cronbach’s alpha met the benchmarks. The quality of the items in the three-dimension model met the benchmark. Eight items were detected as significant DIF items (at α < .01). The loneliness level of Chinese elderly individuals was significantly higher than that of Koreans in Dimensions 1 and 2, while Korean elderly participants showed significantly higher loneliness levels than Chinese participants in Dimension 3. Several collected demographic characteristics and loneliness levels were more highly correlated in Korean elderly individuals than in Chinese elderly individuals. Conclusion: Analysis using the three dimensions is reasonable for the revised UCLA loneliness scale. Good item quality and the items of this measure suggest that the revised UCLA loneliness can be used to assess the preferred latent traits. Finally, the differences between the levels of loneliness in Chinese and Korean elderly individuals are associated with the factors of loneliness.}, number={10}, journal={EDUCATIONAL GERONTOLOGY}, author={Park, In H. and Rachmatullah, Arif and Park, In-Sook and Liu, Yang}, year={2019}, month={Oct}, pages={581–599} }

Many studies have found that overconfidence bias is one of the cognitive biases hindering people from achieving such decision making. Gender and country play crucial roles in overconfidence bias. For instance, some particular cultures and genders tend to be more overconfident than others. However, whether or not the two variables interact to influence overconfidence bias also indirectly influences decision making, especially in the context of science education. The purpose of this study is to identify the effects of country and gender on performance, confidence, and overconfidence bias in the samples of Indonesian and Korean high-school students while doing on a biology exam. The twenty-one American Association for the Advancement of Science (AAAS) questions on the topics of genetics and evolution were administered to 297 Indonesian and 235 Korean high-school students, in their first and second years. Every question was featured with a question asking students how confident they are in answering the question correctly. The two-way Analysis of Variances (2-way ANOVA) test was used to answer the research questions. Based on the analyses, we found no significance interactional effects of gender and country in test scores. In contrast, we found a significant interactional effects in both confidence in genetics and evolution. Regarding overconfidence bias, for which that we merged both concepts, we found that country had a higher influence on students’ overconfidence bias than did gender. Additionally, we found the hard-easy effect phenomenon followed overconfidence bias phenomenon. The relationships between country, gender, science education, cognitive bias, and overconfidence bias are discussed. Suggestions for reducing overconfidence bias are also provided.}, number={5}, journal={INTERNATIONAL JOURNAL OF SCIENCE EDUCATION}, author={Rachmatullah, Arif and Ha, Minsu}, year={2019}, month={Mar}, pages={652–673} }

Even though Indonesia has a unique educational system in which cultural, religious, and cognitive aspects are incorporated in the science K-12 curriculum, a limited number of studies have explored Indonesian students’ attitudes towards science. This research aimed to examine students’ attitudes toward science and the interaction between academic grade level and gender in Indonesian primary and middle school. Thirty items from five components of the BRAINS instrument were administered to 1587 Indonesian students from fourth grade through ninth grade to measure their attitude toward science. Rasch analysis, two-way ANOVA, and structural equation modeling path analysis were used to answer the proposed research questions. The current research found that Indonesian students’ attitudes toward science were significantly affected by academic level, however, gender only affected three components of attitude (control belief, attitude toward the behavior, and intention). Female students showed a higher attitude toward science than male students in general. The trends in every component of the students’ attitudes decreased from primary school to middle school. The present research provides a deeper discussion by considering the socio-cultural and educational history of Indonesia.

We used data from the international survey of 68 countries, and used statistical methods to create the composite scores of every variable. Next, we used Pearson and partial correlations to determine the significance of the relations between the three variables and path analysis to investigate the directions. The correlation coefficient between academic and religiosity variables was a significant and negatively high correlation; furthermore, the partial correlation was strong and significant when the socioeconomic variable was controlled. The correlation between religiosity and socioeconomic variables was a significant and negatively high correlation, and the partial correlation was not significant when the academic variable was controlled for. The correlation between academic and socioeconomic variables was a significant and positively high correlation, and the partial correlation was significant when the religious variable was controlled for. The path analysis reveals that the direction is as follows: socioeconomic, education, and finally, religiosity. Based on our results and the reviewed literature, this paper discusses how these results contribute to the secularization theory and how education mediates religiosity and socioeconomic variable.
