Abstract

The purpose of this study was to determine the development process, validity, and practicality of web-based chemistry learning media on the Periodic System of Elements. The type of research used is research and development (R&D) with the ADDIE development model. This ADDIE development research model consists of 5 stages, namely analysis, design, development, implementation and evaluation. Students of class XI IPA SMAN 3 MATARAM, consisting of six classes, became the population of this study. Cluster random sampling was the sampling method in this study. Cluster random sampling is sampling at the cluster/group level randomly and class XI IPA 3 was chosen as the research sample. The validity test results of the average V value of 0.77 and the average reliability level of R = 85% show that the learning media is valid and reliable. Meanwhile, student responses in the practicality test showed a positive response with an average practicality of 82.06%, so that the learning media developed was classified as very practical. Based on the results of the analysis, the learning media products developed are valid and practical to use in the teaching process.

Abstract

This study aims to develop an e-LKPD based on Project-Based Learning (PBL) integrated with the STEM (Science, Technology, Engineering, and Mathematics) approach for acid-base materials, and to determine the level of validity and practicality. This study uses an R&D development method (Research and Development) 4D model (Define, Design, Develop, and Disseminate). The characteristics of the e-LKPD developed are aimed at catering to students' learning interests, with four key features: contextual, simple projects, gamification, and audio-visual elements. The subjects of the study consisted of 32 students of class XI Phase F at SMAN 6 Mataram. Validity analysis was conducted using the Aiken index (V), which yielded a value of 0.92, indicating that the e-LKPD developed was classified as highly valid. The level of practicality was measured through teacher and student responses of e-LKPD, with a percentage result of 92.95%, which was in the very practical category. Thus, the results of this study indicate that the e-LKPD PjBL-STEM developed has met the criteria of high validity and practicality, making it suitable for use in schools to learn about acid-base materials.

Abstract

This study aims to validate the instrument to measure Gen-Z Pre-service Science Teacher Virtual Lab Acceptance and Use using Rasch model. This study is quantitative survey design with 83 participants from science education major in a new public university in Sulawesi. Instrument of the study is adopted which developed based on the Unified Theory of Acceptance and Use of Technology 2 and the Theory of Planned Behavior. Students are requested to fill up the questionnaire after experimenting basic chemistry courses using pHET virtual laboratory. The instrument has satisfactory reliability (person reliability 0.95, item reliability 0.78 and Cronbach alpha 0.98), separation (person separation 4.32 and item separation 1.68). All item are accepted based on the suitability of item fit statistics by referring to mean square, Z tolerated standard, and point measure correlation. Based on its unidimensionality, the instrument can explained 57.7% variance from item variance 22.7% and person variance 30%. Based on the findings that the instrument is valid and reliable to measure science teacher virtual lab acceptance and use. The findings suggest that validated instruments for measuring virtual lab acceptance can guide educators and policymakers in effectively integrating technology into science teacher training programs, ultimately enhancing educational practices and outcomes.

Abstract

This study aims to reveal the effect of the CINQASE learning model on critical thinking skills and students' conceptual understanding of acid-base titration material at SMAN 6 Mataram. This study is a quantitative study with a quasi-experimental method. The population in this study were students of Phase F Class XI SMAN 6 Mataram. The research sample was taken using the cluster random sampling technique and obtained students of class XI 4 as the control class and students of class XI 3 as the experimental class. The research instrument in measuring critical thinking skills and conceptual understanding was in the form of 5 test questions that had been tested for validity and reliability. The results of the N-Gain values ​​obtained from the experimental class and the control class were analyzed by testing the normality of the N-Gain and homogeneity of the N-Gain first and then testing the hypothesis. Hypothesis testing was carried out using the t-test. The results showed that there was an effect of the CINQASE learning model on students' critical thinking skills and conceptual understanding of acid-base titration material with a significance value of t count > t table. Student responses to the CINQASE model also showed positive results. In conclusion, the CINQASE learning model is effectively applied in chemistry learning to improve critical thinking skills and conceptual understanding.

Abstract

This study aims to analyze the need for further development of the CHEM-RILW model, an extension of the previously developed ILW model. The respondents involved in this study included two lecturers (N = 2) and forty-seven chemistry students (N = 47). Data was collected using observation sheets, questionnaires, critical thinking tests, and rubrics for argumentation and communication skills. The results indicated that the implementation of the learning process successfully integrated investigative activities carried out in the laboratory. This integration demonstrated that the pre-laboratory, laboratory, and post-laboratory stages were effectively implemented. However, the previous model did not sufficiently enhance students' interpretation and presentation skills. Additionally, the human element was not adequately emphasized, which limited the development of students' argumentation skills. Analysis of the lecturer questionnaire revealed a need to improve the learning model by incorporating more real-world applications of theory. Based on these findings, it is clear that further development of the ILW model is necessary. The CHEM-RILW model, as an enhancement, introduces real-world aspects and emphasizes the human element in learning, highlighting the relevance of community science in the context of chemistry concepts.

Abstract

This research aims to determine the effect of the problem-based learning model on the learning outcomes of reaction rate material in class XI students at SMAN 1 Lingsar. The type of research employed is a quasi-experiment, specifically a non-equivalent control group design. The population in this study consisted of all the students in class XI MIPA at SMAN 1 Lingsar, totaling 143 students divided into 4 classes. The sampling technique used is purposive sampling. The samples in this study were class XI MIPA 2 as the experimental class and XI MIPA 3 as the control class. The experimental class employs a problem-based learning model, while the control class utilizes a conventional learning model. The student learning outcomes were focused on the reaction rate material in the cognitive domain. The data analysis test used in this study is the t-test Gain. The gain in the experimental class (0.47) was greater than the gain in the control class (0.28). The analysis results showed that tcount (3.45) > ttable (2.03) at the 5% significance level, indicating a positive and significant effect of the problem-based learning model on the learning outcomes of reaction rate material for class XI students at SMAN 1 Lingsar.
