Abstract

The use of technology is currently relevant to the implementation of the ‘Merdeka Belajar’ Curriculum, but has an impact on students' critical thinking skills and learning media needs. This means that educators need to provide innovation in learning that is linked to technology. This study purpose to analyze the validity and readability of Google Sites learning media with a STEM approach to mutation material. This study used research and development (R&D) methods but was limited to the implementation stage, namely small-scale testing. A small-scale trial was carried out on 20 students of class XII MIPA 2 at Gemuh 1 Senior High School. The instruments used in this study were validation sheets and media readability questionnaires. Product validity criteria are seen from the validator's assessment. Criteria for media readability are seen from the results of student questionnaires. The study results show that the validity of the media was declared very valid based on the assessment of media experts at 96% and material experts at 93.56%. The media readability value was declared very good based on student assessments of 88.64%, so it has the potential to improve high school students' critical thinking skills.

Abstract

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. This study also showed that the CPS-STEM learning model was effective in enhancing digital literacy skills with a percentage increase of 15.25%

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.

Abstract

Heavy metal pollution is an environmental problem that directly impacts human health and the sustainability of aquatic ecosystems. Research indicates that the issue of heavy metal pollution can be used as a contextual learning resource to foster students’ digital literacy skills and environmental awareness. Preliminary observations at SMP Negeri 1 Boja revealed that students’ digital literacy skills remain relatively low, indicating the need for innovative learning resources to enhance these competencies. This study aims to develop a research-based digital teaching supplement on heavy metal pollution to equip junior high school students with digital literacy skills. The research employed the ADDIE model, comprising the stages of analysis, design, development, implementation, and evaluation. The study involved eighth-grade students at SMP Negeri 1 Boja during the 2024/2025 academic year. Data analysis used descriptive statistics to assess validity and practicality, as well as percentage achievement analysis to evaluate students’ digital literacy. The results show that: (1) material expert validation scored 91.54% (very feasible) and media expert validation scored 93.07% (very feasible), (2) student responses indicated a practicality score of 93.06% (very practical), and (3) students’ digital literacy averaged 85.74% (very good) across the five aspects: accessing (90.00%), selecting (83.97%), understanding (90.15%), evaluating (80.44%), and producing (84.12%). These findings demonstrate that the developed research-based digital teaching supplement is highly feasible, highly practical, and effective in equipping students with strong digital literacy skills.
