Abstract

A student's motivation influences students' self-regulatory abilities, and significantly impacts their attitude towards scientific concepts, contributing to a more enriched and successful learning experience. This research explores the correlation between motivation and self-regulation in science learning among junior high school students. The research methodology employed in this study adopts a quantitative approach with a survey research design. This research found that the average learning goal orientation is 4.12, task value is 3.97, and self-efficacy is 3.75. The total average for the dimensions of motivation and self-regulation is 3.95 and 3.89 respectively. These scores indicate that the motivation and self-regulation in science learning among junior high school students are categorized at a high level. Furthermore, there is a significant correlation between motivation dimensions (learning goal orientation, task value, and self-efficacy) and self-regulation in science learning. Based on the students’ answers to open-ended questions, they are motivated to learn science because learning science is interesting and fun. Meanwhile, students who feel unmotivated to learn science find it challenging, especially when dealing with formulas and calculations. However, despite the lessons' difficulty, students still try to study because most of them desire to achieve good grades in science lessons.

Abstract

This study aims to determine the impact of utilization Computer Assisted Instruction (CAI) based learning media in improving digital literacy skills and student learning outcomes. In this study, data collection used observation sheets to improve students' digital literacy skills through observations of experimental and control groupes. It is known that the score of students' digital literacy skills is 81% in the experimental group, while the control group is 67%, meaning that the criteria for students' digital literacy skills in the experimental group are classified as better.  In collecting data to determine the effect of media on student learning outcomes, the Pretest Posttest control group design method is used with a pretest, treatment, and posttest pattern. In practice, 2 groupes are needed as experimental groupes with treatment and control groupes without treatment, and observations are made of students' digital literacy skills during learning activities. From the results of the analysis of student pretests and posttests, it is known that there is an increase in scores in the experimental group as indicated by the average N-Gain value of 57.54%, thus the use of CAI-based learning media is interpreted in the category quite effective in improving student learning outcomes. Then based on the results of the one-way anova analysis for the relationship between the improvement of learning outcomes with digital literacy skills in experimental and control groupes, it is known that the significance value is 0.00 <0.05, as well as the results of the post-hoc test with the Turkey method which shows the significance value between digital literacy and learning outcomes is less than 0.05, which means that the use of CAI-based learning media has an influence on digital literacy as well as student learning outcomes. So it can be concluded that the use of CAI-based media has an impact in improving digital literacy skills and student learning outcomes.

Computational Thinking (CT) and digital literacy are skills students must possess to adapt and survive amidst the current technological advancements. One way to enhance students’ CT and digital literacy skills is through innovative learning models that align with the material being taught. Biotechnology is one of the subjects that students need to master in Phase E of the Merdeka Curriculum. This study aims to determine the effectiveness of the CPS-STEM learning model on students’ CT and digital literacy skills in biotechnology material. This research was conducted from April to May in the 2023/2024 academic year at three high schools in the Kayen, with a total population of 891 students. The sample used in this study was calculated using the Slovin formula, its 8 classes consisting of 2 control groups (72 students) and 2 experimental groups (217 students). This study is a quasi-experimental design with a pre-test and post-test group design. The STEM approach is integrated with CPS syntax outlined in the teaching module and assisted with student worksheets. CT skills were measured using post-test instruments, while digital literacy skills were measured using questionnaire. Data analysis was conducted to determine the effectiveness of the CPS-STEM learning model on CT skills, calculated using the N Gain test, while digital literacy skills were measured using a Likert scale. The results showed that the CPS-STEM was effective to improve CT skills in the medium category (0.40), whereas the direct instructional learning model was not effective in enhancing CT skills.
