Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran inkuiri terbimbing terhadap sikap ilmiah siswa pada materi termokimia di kelas XI MIPA SMAN 3 Mataram. Populasi dalam penelitian ini adalah seluruh siswa kelas XI MIPA SMAN 3 Mataram. Pemilihan atau pengambilan sampel pada penelitian ini menggunakan purposive sampling. Sampel dalam penelitian ini adalah kelas XI IPA 1 sebagai kelas kontrol yang diberi perlakuan model pembelajaran konvensional dan kelas XI IPA 6 sebagai kelas eksperimen yang diberi perlakuan model pembelajaran inkuiri terbimbing. Pengumpulan data dalam penelitian ini dilakukan dengan menggunakan metode sebagai berikut: (1) angket dan (2) observasi. Hasil uji hipotesis dengan uji Independent Sample T-test menunjukkan bahwa thitung (2,16) > ttabel (1,67) pada taraf signifikan 5% yang berarti Ho ditolak dan Ha diterima sehingga dapat disimpulkan bahwa model pembelajaran inkuiri terbimbing berpengaruh positif terhadap sikap ilmiah siswa pada materi termokimia kelas XI SMAN 3 Mataram.

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 study aims to determine the effect of Augmented Reality media on the conceptual understanding of eleventh-grade students at SMAN 1 Pujut on the topic of acids and bases. The research design used is a quasi-experiment with a nonequivalent control group design. The population for this study consists of tenth-grade students at SMAN 1 Pujut. The research sample includes class XI F1 as the experimental group (23 students) and class XI F2 as the control group (20 students). The learning outcome instrument is a post-test in the form of multiplechoice questions. Quantitative data analysis was performed to test the hypothesis using a t-test. The results show that the calculated t-value (3,84) is greater than the table t-value (2.01), which means that the null hypothesis (H₀) is rejected, and the alternative hypothesis (Hₐ) is accepted. The results of the student response questionnaire to the application of Augmented Reality learning media on acid-base material showed that the number of students who stated Strongly Agree (SS) was 44%, Agree (A/S) was 34%, Disagree (D/TS) was 17%, and Strongly Disagree (SD/STS) was 5%. Thus, the average percentage of Strongly Agree and Agree choices was 78%. Therefore, it can be concluded that there is an effect of using Augmented Reality media on the conceptual understanding of eleventh-grade students at SMAN 1 Pujut.

Abstract

This research is development research or Research and Development (R&D) which aims to produce Student Worksheets (LKPD) which are categorized as minimally feasible and practical. The research and development model used in this research is a 4D model which consists of four stages, namely defining, designing, developing and disseminating. In this research, the 4D model is limited to the development stage. Validation of the LKPD was carried out by two Chemistry Education lecturers and two Chemistry subject teachers at high school level. Data analysis in the expert validation test uses the Aiken's V Index formula. The validation results show that the LKPD validity index is generally 0.84 with a very valid validity category, which means the LKPD is very feasible based on validity. After the LKPD was tested for validation and revision, it was then tested for practicality on 25 students and 2 chemistry subject teachers. The test results show that the practical level of LKPD generally reaches 86% based on student responses and 95% based on teacher responses, both of which are classified as very practical. Based on this, this LKPD is declared very suitable for use as a learning medium regarding acid-base solutions at the high school level.
