Analysis of Diagnostic Assessment in the Science Subject for 4th Grade Elementary School
Get PDFDiagnostic assessment plays a crucial role in the learning process, particularly in identifying students' prior knowledge and learning needs before instruction begins. This study aims to analyze the implementation of diagnostic assessment in the IPAS (Science and Social Studies) subject for fourth-grade elementary school students. A qualitative descriptive approach was used to examine how diagnostic assessments are conducted and their impact on student learning outcomes. Data were collected through classroom observations and student performance analysis. The results indicate that diagnostic assessments help teachers design more effective learning strategies tailored to students’ abilities. However, some teachers do not fully implement diagnostic assessments, leading to disparities in students’ understanding of the material. The findings emphasize the need for proper training and structured implementation of diagnostic assessments to enhance students’ critical thinking skills and improve overall learning outcomes
Analyzing Student Reactions to Interactive Learning Materials and Critical Thinking Capabilities Using the Rasch Model
Get PDFBy creating interactive learning materials for the biochemistry course, this project seeks to improve the critical thinking abilities of students enrolled in the Science Education Program at one of the Bengkulu universities. Employing a research and development (R&D) approach considering the DDD-E (Decide, Design, Develop, Evaluate) model, the media was designed for Android devices and focuses on carbohydrate metabolism content. The main features include Program and Course Learning Outcomes, instructional materials, usage guidelines, and a profile section. Validation results from content and media experts confirmed the media’s appropriateness for instructional use. Student responses, analyzed using the Rasch Model, indicated strong agreement regarding the media's usefulness. Moreover, the application of this interactive media significantly improved students' critical thinking skills, with an N-gain score of 53.67%. These findings suggest that the media is effective for use in biochemistry courses, although further research is needed to explore its application in other subject areas
Are Scrapbooks Able to Increase Tsunami Disaster Literacy? An Analytical Study of Junior High School Students Materials
Get PDFTsunami disaster mitigation is a crucial aspect of enhancing community preparedness, particularly among junior high school students in tsunami-prone areas. However, students' disaster literacy remains low due to the lack of engaging and interactive learning media. This study aims to develop and evaluate the effectiveness of Scrapbook-based learning media in improving students’ tsunami disaster literacy. Using a Research and Development (R&D) approach, this study follows the ADDIE model (Analysis, Design, Development, Implementation, Evaluation) and employs a mixed-method approach combining quantitative and qualitative methods. The research involved four expert validators (material, media, language, and disaster mitigation practitioners) and 65 students from Al-Amin Junior High School, with an initial trial conducted on 15 students. The validation results indicate that the developed Scrapbook media is valid, with an average assessment score of 84%. The paired sample t-test revealed a significant improvement in students' disaster literacy, with a significance value of 0.000 < 0.005. These findings demonstrate that Scrapbook media effectively enhances students' understanding of tsunami disaster mitigation. The implications of this study highlight the importance of integrating interactive and visually engaging learning media into disaster education curricula to foster student engagement and strengthen their preparedness for future disasters
Developing Android-Based Interactive Multimedia with Madurese Culture to Enhance Students’ Learning Outcomes in Classroom Action Research
Get PDFThis study aims to improve Grade VII students’ learning outcomes on the topic of the Life Organization System by implementing the culturally responsive “Bebek Songkem” Android-based interactive multimedia. The media was designed to address students’ difficulties in understanding abstract biological concepts while providing contextual learning linked to local Madurese culture. The research employed the Classroom Action Research (CAR) model of Kemmis and McTaggart, consisting of the stages of planning, action, observation, and reflection. The participants were 30 students of Class VII-B at UPTD SMPN 5 Bangkalan. Data were collected through pre-tests and post-tests in each cycle and analyzed using gain score. The results showed a consistent improvement in learning outcomes. In Cycle I, the average score increased from 33.33 to 57.00 with a gain score of 0.355 (moderate). In Cycle II, the mean score increased from 43.33 to 86.00 with a gain score of 0.761 (high). These findings demonstrate that integrating local cultural elements into interactive multimedia can enhance students’ comprehension, engagement, and overall science learning performance
Implementation of Practicum Method as a Strategy to Strengthen Science Process Skills at Secondary School Level
Get PDFScience process skills are an important aspect in science learning and play a role in training students' scientific thinking skills. However, facts in the field show that students still have difficulties in making systematic observations, formulating hypotheses, designing and conducting experiments, and interpreting data appropriately. This condition is exacerbated by the lack of practicum activities that can train science process skills. The purpose of this study was to describe the implementation of the practicum method on the science process skills of junior high school students. This type of research is a quasi-experiment with a non-equivalent control group research design. The study population was 115 students and the sample was 46 students. The sampling technique used random sampling which was grouped into control and experimental classes. The data analysis technique used N-gain and Mann Whitney test. The results showed that there was no increase in science process skills in the control and experimental classes. In addition, there was no significant difference between the science process skills of the control and experimental classes. It can be concluded that the practicum method in this study did not have an impact on students' science process skills
