Socio-Scientific Issue Application in the PBL Model: Is that Effective in Improving Chemical Literacy?
Get PDFScience education, especially chemistry, emphasizes the application of science to solve problems encountered in daily life to foster chemical literacy skills. This study aims to prove the impact of socio-scientific issue (SSI) application in the problem-based learning (PBL) model on student's chemical literacy ability on acid and base materials. This study employed a quasi-experimental method through a pretest-posttest nonequivalent control group design. Its population consisted of 11th-grade science students from one of Surakarta's public high schools in the 2023/2024 academic year. It used class XI.6 as the control class and class XI.7 as the experimental class. The sample was established using the cluster random sampling technique. Based on the analysis of the hypothesis test carried out with the independent sample t-test, the Sig. value is 0.000. The mean chemical literacy score in the experimental class is 72, whereas that in the control class is 62. The enhancement of chemical literacy in the experimental class is 63% (quite effective), while that in the control class is 50% (less effective). This proves that the effect of SSI application in the PBL Model on students' chemistry literacy ability was more significant than the PBL without SSI applicatio
Assessing Students' Numeracy Literacy Level using The Ethnoscience-SSI Integrated Test on Acid-Base Material
Get PDFNumeracy skills in the 21st century are essential because these skills not only support data analysis and number-based problem solving but are also needed in various aspects of life that affect the global community. The numeracy literacy of high school students has not been optimally trained, even though both abilities are needed to solve conceptual and contextual daily life problems in working on PISA and AKM items. This study was conducted to assess the numeracy literacy level of high school students in one of the cities in Central Java Province. As a survey with a quantitative approach, this study involved 150 high school students as respondents. The entire population became respondents in this study so the purposive sampling technique was applied. 24 out of 30 test items are empirically valid with a reliability value of 0.89. Data analysis was conducted using descriptive statistics to answer the numeracy literacy category of students. Based on the results, 35.60% was obtained which is included in the knowing level of numeracy literacy. The results of this study suggest more interactive and contextualized learning strategies to facilitate the transition to deeper understanding and application level

Enhancing Collaborative Teaching Through Developing Website-Based Learning Materials for Lecturers at Makassar Aviation Polytechnic
Get PDFThis study aims to develop a website-based Learning Material Collaboration System (LMCS) for lecturers at Makassar Aviation Polytechnic. The system is designed to facilitate online collaboration in preparing teaching materials, ultimately enhancing the overall quality of learning using the waterfall method. Currently, teaching materials at the institution are independently prepared by the lecturers responsible for their respective courses, which results in non-standardized materials and limited collaboration between lecturers, practitioners, and cadets. The resulting materials are more comprehensive and sustainable through collaborative efforts in preparing teaching materials. The application requires lecturers to create an account, ensuring only authorized individuals can contribute and compile the teaching materials. This study proposes a collaborative platform that allows teaching materials to be prepared online to improve the effectiveness of learning and the quality of teaching materials. The LMCS application was tested to evaluate its reliability, efficiency, and effectiveness. The test results showed that the application effectively supported the collaboration of teaching materials, although some obstacles remained in managing cadet groups. Based on usability testing conducted with 10 participants, the application was user-friendly, with most testers successfully completing nearly all tasks. Analysis of the questionnaire using a Likert scale revealed positive user feedback, with the ease of use aspect scoring 82.6% and usability achieving a high score of 87.3%. Users felt that the application accelerated and facilitated the collaboration of teaching materials among lecturers and improved operational efficiency. However, for further development, training on the application and improvements to the user interface (UI/UX) are needed to ensure optimal use by all levels of users. The results of this study are expected to contribute to improving the quality of teaching materials and institutional accreditation at Makassar Aviation Polytechnic
Integrating Psychological Stress Indicators with Academic Data for Student Dropout Prediction: A Decision Tree and Expert System Approach
Get PDFStudent attrition remains a major problem in higher education. Although academic variables are well-established moderators, psychological wellness, especially stress, is an important but often ignored moderator. The purpose of this study is to construct prediction models for students at risk of dropping out by combining academic and psychological information. One major challenge in this field is the class imbalance of student records, which results in a significant drop in the dropout rate compared to the general population. Therefore, in this study, we employ a Decision Tree algorithm and use a Forward Chaining inference engine along with the Synthetic Minority Over-sampling Technique (SMOTE) to solve it. We employed a data set of 122 students at one institution, with psychological stress scores generated from a standardised questionnaire according to well-known symptom domains. The accuracy for the model with only a Decision Tree was 95.83%. For the stress score, integration with the FC-based attribute increased performance to 96.67%; however, this model exhibited only marginal improvement over the final model due to its very low accuracy when compared to that of SMOTE. This ensemble model performed the best with an accuracy of 97.50% and an AUC of 96.35%. This progression demonstrates that even though the introduction of psychological information is beneficial, an approach to balance data and ensure a robust prediction system is required. This article is a proof-of-concept analysis which creates an opportunity for universities to establish proactive, early-warning-driven models; yet there is a requirement for future validation studies on larger and more diversified samples
