Macroeconomic Determinants of Unemployment in ASEAN Countries: Implications for Education and SDGs
Unemployment remains a persistent challenge for many ASEAN countries and reflects not only economic instability but also the effectiveness of education systems in preparing a productive workforce. Macroeconomic conditions such as economic growth, inflation, foreign investment, and exchange rate fluctuations may influence labor market outcomes and the absorption of human resources. This study aims to analyze the effects of macroeconomic variables on unemployment in ASEAN countries and to examine their implications for education and sustainable development. The study employs panel data regression analysis using secondary data from eleven ASEAN countries during the 2021–2023 period obtained from the World Bank database. Model estimation was conducted using the Pooled Least Square, Fixed Effect Model, and Random Effect Model approaches, followed by model selection tests. The findings indicate that inflation and exchange rates significantly affect unemployment, while economic growth and foreign direct investment do not show a significant influence. These results suggest that macroeconomic stability plays an important role in shaping employment opportunities and workforce outcomes in the ASEAN region. The study contributes empirical evidence linking macroeconomic dynamics with labor market conditions and provides insights for education and employment policies aligned with the Sustainable Development Goals.

Development of Social Emotional Competency Assessment Instruments: Proof of Conten Validity and Inter-Rater Reliability
Social Emotional Competence (SEC) was one of the components of 21st-century education that was considered very important for students in preparing for future needs and challenges. The number of SEC assessment instruments was limited; therefore, it was necessary to develop SEC assessment instruments. An instrument had to be tested for validity and reliability before being used, so validity and reliability testing were crucial during the development process. This study aimed to test the content validity and inter-rater reliability of the developed SEC instrument. The study was a type of Research and Development (R&D). Content validity analysis used Aiken’s V, while reliability was analyzed using the Ebel formula. The results of the content validity based on assessments from 5 experts showed that the average Aiken’s V value was 0.847, which indicated a coefficient value > 0.80. Inter-rater reliability, analyzed using the Ebel formula, yielded a reliability coefficient value of 0.962. These findings proved that the SEC assessment instrument for students was valid and reliable and could be used for field testing.
The Mathematics Creative Thinking Skills on the Connecting, Organizing, Reflecting, and Extending (CORE) Learning Model Seen from Students Independence Assisted by Contextual Module
The goal of this research is to pinpoint the underlying factors contributing to students' poor mathematical creative thinking skills and to evaluate the impact of CORE learning with contextual modules on these skills. This research method uses a mixed-method approach with a sequential exploratory strategy, which involves the sequential collection of qualitative and quantitative data. The population in this study is the seventh-grade students of SMP N 3 Kandangan for the 2021/2022 academic year. The researchers collected data through observation, interviews, tests, and questionnaires. The researchers analyzed the data descriptively, using both qualitative and quantitative methods. The research findings indicate that the CORE learning model, in conjunction with contextual modules, can effectively address the factors contributing to low mathematical creative thinking skills. CORE learning assisted by contextual modules is effective in terms of student independence. The skills to think creatively in mathematics during CORE learning assisted by contextual modules shows that students achieve above the Minimum Completeness Criteria (KKM) of 70. When students think creatively in mathematics during CORE learning with contextual modules, their completeness surpasses the KKM by more than 75%, resulting in a 31% improvement on the Gain Test. Students with high independence are able to meet all four indicators of mathematical creative thinking skills, namely fluency, flexibility, originality, and elaboration. Students with low or very low independence can only meet two or three indicators of mathematical creative thinking skills, such as fluency, flexibility, and originality, but are unable to meet one of the other indicators.

Mobile devices and learning: Student perspectives and inclination at South African higher learning institutions
The increasing use of mobile devices in business extends to academia, posing challenges for educators amid the dynamic landscape of teaching and learning methods. Educators must adapt to these changes to meet students' technology-driven learning needs. This study investigated students' perspectives on mobile device usage and their inclination to integrate the use of mobile devices into learning activities. In a self-administered LimeSurvey questionnaire, students demonstrated a positive attitude towards mobile device use in learning and expressed optimism about its future potential. Exploratory factor analysis identified three key factors that influence mobile device selection for learning: behavioural lifestyle intentions, subjective social norms, and attitude and expectations. A multiple linear regression analysis revealed that these factors are predictors of the use of mobile devices for study and learning purposes. Institutions and educators should leverage these insights to enable students to acquire mobile devices, either as part of study material or through loan schemes or financial assistance.
Bridging the Gap: A Bibliometric Analysis of Differentiated Learning Research in Indonesia and Global Contexts
Implementing differentiated learning in Indonesia has several problems despite its vital role in improving educational quality. This study examines the disparity between research on differentiated learning in Indonesia and global research by doing a bibliometric analysis. The methodology utilizes bibliometric analysis of research literature on differentiated learning from the Scopus database. Data analysis involves examining research productivity, the extent of international collaboration, and the trends in research topics. The key findings suggest that although Indonesia has many writers contributing, its research has not achieved much global attention. In Indonesia, research primarily focuses on implementation within the context of national policies. However, global research has a broader reach, encompassing modern technology and an array of methodologies. These findings suggest that Indonesian researchers should broaden their research scope, enhance international collaborations, and investigate areas such as applying advanced technologies in customized education, the long-term effects on learning achievements, and creating tailored learning models suitable for the Indonesian context. As a policy recommendation, the government could offer targeted incentives to promote international research collaborations and establish online collaboration platforms to enhance cross-country cooperation in differentiated learning.
Scale Validation and Impact of Program Difficulty and Study Habits on Performance among Undergraduate Pharmacy Students
Study habits and program difficulty in the context of academic performance are critical considerations among undergraduate pharmacy students. However, a robust, validated measurement instrument is absent to evaluate the relationship between study habits, program difficulty, and academic performance from students' perspectives. 352 undergraduate pharmacy students [195{55%) females and 157 (45%) males] from 3 public Universities in Nigeria were surveyed. Structural equation modeling was used to develop and test the model validity using exploratory and confirmatory factor analysis (EFA and CFA). EFA extracted a three-factor structure aligned with the theorized framework. CFA revealed adequate model fit and construct validity. Measurement invariance analysis showed configural, metric, scalar, and residual invariance by gender, age, class, and University. Study habits positively influenced students' performance while program difficulty had a negative impact. We propose a robust, validated instrument-program difficulty, study habits, and academic performance scale useful for academicians, educational and curriculum managers
