Abstract

Research was carried out with the aim of finding out blended learning on the independence and learning outcomes of class XI MAN 1 Makassar City students. A posttest only control design was used in this research, which is a type of quasiexperimental research. Entire class of XI MAN 1 Makassar City, consisting of 12 classes, was used as the population, then selected by random sampling to obtain 4 classes as samples consisting of 3 experimental classes and 1 control class. Implementation of learning in experimental group used an ICT-based MPBK model with blended learning approach, while in the control group used direct instruction learning model with teacher-based learning approach. Data collection on learning independence is non-test instrument in the form of questionnaire and data collection on learning outcomes is test instrument in form of objective and subjective questions. Data results were then analyzed using descriptive statistics followed inferential statistics. Results of the descriptive analysis showed that the experimental group had better independence and learning outcomes than tcontrol group. Results of the inferential analysis used normality tests, homogeneity, hypothesis testing with multivariate analysis of variance tests and further Tukey HSD tests. From hypothesis testing it was found that the significance value was 0.000 < 0.05, so there was influence of blended learning on independence and learning outcomes of class XI MAN 1 Makassar City students. Results of further tests with Tukey HSD for independence and learning outcomes showed that experimental and control groups were in different subset columns so that there were significant differences between groups, which means that statistically blended learning has influence on students' independence and learning outcomes.

The aim of this research is to analyze students' perceptions regarding the application of artificial intelligence in science learning materials. The research method used in this study is a descriptive quantitative approach to evaluate the perceptions of elementary school students towards the implementation of artificial intelligence (AI) in science education in Makassar in June 2024. Data analysis techniques involve descriptive statistics. The subjects of the study consisted of 26 students, with instrument being a 24-item questionnaire using a Likert scale from 1 to 5. This questionnaire was designed to assess students' learning experiences, interests, motivation, benefits, impacts, as well as challenges and expectations. The results indicate that the use of AI in science learning has a significant positive impact, enhancing students' learning experiences, interests, and motivation. The majority of students reported that AI aided them in understanding the material, exam preparation, and learning outcomes. However, there were some challenges such as technical issues and adaptation that need to be addressed. Students have high expectations for the sustainability of this technology. To optimize the benefits of AI and overcome challenges, technical support, training, and adequate infrastructure are needed so that all students can equitably benefit from this technology.

Abstract

This study aims to build and analyze the SELR mathematical model in the context of the Independent Curriculum, in order to explore and predict the gap in student achievement between urban and remote areas in South Sulawesi. This study combines theoretical studies and applications by conducting simulations using Maple software. The study population involved 400 students from urban areas and 400 students from remote areas where simulation data was used to predict the dynamics of adaptation to the Independent Curriculum. The results showed that the Independent Curriculum was not fully effective in addressing the achievement gap, with a low basic reproduction number (R₀), both in urban and remote areas. The R₀ value of 0.204 in urban areas and 0.614 in remote areas indicates that the spread of curriculum adaptation is still limited and cannot create a significant impact on improving student achievement. This study indicates the need for additional adjustments and interventions in the implementation of the Independent Curriculum to achieve more equitable and inclusive results in various regions .
