Abstract

The study investigates the performance of students in constructing Concept Maps (CM) related to environmental pollution material during the COVID-19 pandemic. The data reveals that the overall achievement in CM construction was suboptimal, with no component reaching more than half of its maximum potential. The highest achievement was recorded in the valid relationship component, which attained 9.75% of its maximum possible score. This was followed by the hierarchy component, achieving 7.34%, and the branching component at 3.42%. The pattern component ranked fourth with 1.31%, closely followed by the example component at 1.30%. The lowest performance was observed in the crosslink component, with an achievement of 0.00%. The analysis suggests that students struggled significantly with constructing comprehensive and complex CM, indicating a need for further instructional support. The low scores, particularly in critical components such as crosslinks and examples, highlight gaps in students’ ability to synthesize and analyze information, which are vital for developing more advanced CM. These findings point to the importance of enhancing students’ conceptual understanding and analytical skills to improve their learning outcomes, especially in the context of environmental pollution education during the challenges posed by the pandemic.DOI: 10.17977/jps.v12i42024p141

Abstract

Hermetia illucens larvae, also known as the black soldier fly larvae, are best known as the decomposers of organic matter. There are many potential microbes found in the feces of BSF larvae. This research aimed to isolate the chitinolytic bacteria from chicken manure maggot waste, identify the antifugal activity, hydrolytic enzyme activity, phosphate and potassium solubilization, and bacterial species through 16S rRNA gene analysis. The initial screening focused on bacteria with chitinolytic ability. Antifungal activity tests were performed against phytopathogenic fungi, Colletotrichum sp. Isolate MKP02 showed the highest activity in inhibiting the growth of Colletotrichum sp. up to 100% and produced protease and cellulase enzymes, along with the ability to solubilize potassium. Furthermore, the potential isolate MKP04, the isolate shows the highest cellulolytic activity with a percentage of 300%. It can inhibit Colletotrichum sp. fungi, as well as having lipase enzyme content, and being able to dissolve potassium. The results of 16S rRNA gene amplification on the two isolates showed that both isolates were close to bacteria of the genus Lysinibacillus and Brevibacterium. This research is expected to provide valuable information about the bacterial content, levels of hydrolytic enzymes, and the ability to solubilize phosphate and potassium in BSF.

Abstract

This study aims to compare the results of instrument testing methods between applying classical test theory and item response theory using the Rasch model in question instruments on respiratory system material. This study employed descriptive quantitative methodology, with a sample involving 36 students. The analyzed instrument consisted of 40 multiple-choice questions on respiratory system material. Instrument analysis utilized classical test theory with Microsoft Excel and item response theory with Winstep Rasch ver 4.5.2.0. The data analysis from classical test theory and item response theory offers slightly different interpretations but is mutually complementary. Both classical test theory and item response theory may assess the validity, reliability, distractor effectiveness, difficulty level, and discriminating power of questions. Item response theory provides a comprehensive analysis of test results through the use of the Wright map as a bar which helps determine a student's ability about the difficulty level of the question. Scalogram is used to identify patterns in students’ responses, allowing for the detection of cheating and inaccuracies in answering questions. Additionally, DIF items are employed to identify item bias. This study concludes that any developed instrument must possess the characteristics that meet the requirements to measure competency effectively. The requirements for an instrument can be analyzed using item response theory with the Rasch model, which provides in-depth interpretation.Keywords: Classical test theory, item response theory, Rasch model, instrument

Abstract

Science process skills are an essential aspect that supports critical, creative, collaborative, and communicative thinking skills. The reality reveals that science learning in schools is still dominated by traditional methods focusing on memorising concepts. Project-Based Learning (PjBL) offers a promising approach to improving KPS. PjBL is a student-centred learning model, where students work collaboratively to design, implement, and evaluate projects that are relevant to real life. This study determines the effect of the project-based learning model on empowering students' science process skills by using a systematic literature review (SLR). Systematic Literature Review involves searching and analysing relevant literature from various sources published from 2016 to 2024. A systematic method could identify relevant literature studies to the pre-determined criteria. The applied content analysis ensured the model, method, focus, and results achieved from the study. The results indicate that (a) project-based learning improves students' science process skills, (b) project-based learning is feasible to use for teaching and learning activities, and (c) project-based learning is effective in science learning, especially for improving science process skills. Educators are advised to consider using the project-based learning model in learning strategies to support students' science skills development comprehensively.

Abstract

This study aimed to investigate the validity, reliability, scale understanding, item difficulties, and bias items of the instrument for analyzing the needs of biology teachers regarding the assessment of creative thinking skills using the RASCH model. The instrument was modified based on the indicators of divergent and convergent thinking processes in the scientific learning stages integrated with the dimensions of creative thinking skills by using ADDIE research model. The research participants comprised of 104 participants from the Solo Raya area, those of whom were 64 Senior High School Biology teachers and 40 Junior High School Science teachers. The research instrument used inventory with a Likert scale of 1 to 4. The instrument validity, reliability, scale understanding, item difficulties, and bias items were analyzed by applying the RASCH model using Winstep 3.73. The research results showed that the overall validity was acceptable, and the item validity did not need improvement. Overall reliability was very good, and the item reliability was excellent. Rating scale analysis showed respondents had understood the Linkert scale of 1 to 4 well. Based on the item difficulties results of the teachers' responses, it was found that there had not been any teachers who evaluated the indicators of creative thinking skills by using writings or pictures in problem-solving assessment. The bias test results on the instrument items indicated that five items could potentially be biased due to age difference, and the two others were due to gender type. Therefore, the development of assessment instruments for creative thinking skills with scientific and social problem-solving based assignments, as well as writing and visual expressions, is required.
