Abstract

This study aims to produce a valid four-tier multiple-choice diagnostic test instrument based on validity and reliability and to detect students misconceptions the concept of chemical bonds using the developed instrument. The research design used in this development uses research and development (R&D) of Thiagarajan's modified 4D model consisting of four stages, namely the stages (define, design, develop, disseminate). Based on the results of the study, it can be concluded that (1) the validity of the instrument who reviewed from the content and construct aspects has a score mode of 4, (2) the Cronbach Alpha value is 0.825 which means it is reliable and (3) the misconception profile owned by students for each sub-material of ionic bonds is 33%, metal bonds are 40% and covalent bonds are 51.51%. Based on the results of validity and reliability, the diagnostic test instrument developed can be declared valid for use.

Abstract

In the 21st century, learning is increasingly sophisticated but the utilization of technology by teachers is not optimal so that students are less motivated to learn chemistry and have an impact on learning outcomes. Implementing Instagram reels as a learning resource can make chemistry learning more interesting, creative, and innovative so that it is possible to increase students' chemistry learning motivation. The purpose of this study was to determine how the effectiveness of Instagram reels as a learning resource on students' chemistry learning motivation. The research method used was quasi experiment with nonequivalent control group design. The instrument used was a learning motivation questionnaire. The Mann Whitney test results showed an Asymp. Sig. value of 0.000 <0.05 so that H0 is rejected and H1 is accepted. Thus, it can be concluded that the implementation of Instagram reels as a learning resource effectively increases students' chemistry learning motivation.

Abstract

Scientific literacy can be understood as students’ capacity to apply scientific knowledge, recognize problems, and formulate conclusions based on evidence. This study was conducted to examine the level of scientific literacy among students at SMA Negeri 2 Muara Badak. A descriptive quantitative research design was selected because the purpose was to portray a single variable independently without linking it to other variables. The research population comprised all eleventh-grade science students at SMA Negeri 2 Muara Badak. Using a saturated sampling technique, all students from three classes XI IPA 1, XI IPA 2, and XI IPA 3, were included, totaling 77 participants. Data were gathered through literacy test instruments as well as non-test methods, including observation sheets, student response questionnaires, and interviews. The results indicated that students’ scientific literacy was still within the moderate category, with an achievement percentage of 67.45%. Several factors contributed to this outcome, such as students’ limited reading habits related to science, their relatively weak comprehension of subject matter, and instructional processes that tended to be teacher-centered rather than promoting independent inquiry and conceptual engagement.

Abstract

Critical thinking skills and knowledge learning outcomes are very important for students in today's chemistry learning. However, the results of the PISA test, preliminary studies, and previous research indicate that both aspects still need to be improved. This study uses an R & D approach utilizing the ADDIE model to create a chemical bond e-magazine based on the SCT model that is valid, practical, and effective in enhancing critical thinking skills and knowledge learning outcomes. This study involved five expert validators and 66 grade XI students of SMA Negeri 8 Banjarmasin. The data were gathered through questionnaires, observation sheets, and tests, and then analyzed descriptively. The findings revealed that (1) the e-magazine produced demonstrated a high level of validity (90%) in terms of content, presentation, language, and media, (2) practical with an average score of 88%, and (3) effective with an N-Gain of 0.71 (critical thinking) and 0.75 (knowledge) categorized as high, with an average achievement score of 83%.

Abstract

As an island region on the outer edge of Indonesia, learning processes on Sebatik Island require learning materials that improve students’ system thinking skills, which contain the abilities to identify parts of systems and their interactions, identify cause and effect, organise their relationships among parts of systems, and hold ownership for their environment. According to those significant abilities for Sebatik’s students, this study aims to develop a systems thinking-based e-module on environmental chemistry that aligns with the contextual characteristics of Sebatik Island. With the availability of learning media in the form of system thinking-based e-modules on environmental chemistry, it is hoped that students' understanding of contextual chemistry in accordance with the nature of Sebatik Island will improve. This study applies the Research and Development (R&D) method by adopting the development stages in the ADDIE model, focusing on the development and validation of a newly developed e-module. However, this research focuses on the development stage, taking into account the conditions of the region and the time frame of the research. 10th-grade MIPA students from SMA/MA participated in providing feedback on the e-module through student response sheets,this module has been validated by subject matter and media experts and evaluated by teachers to assess its suitability and effectiveness. The validation results show that the subject matter aspect achieved a score of 98.6% (very good), the media aspect 86.7% (very good), and the teacher's assessment 93.33% (very good). Student responses were also positive, with a percentage of 97.3% (very good). Based on these results, the system thinking-based e-module developed is suitable for use as an alternative learning medium, capable of facilitating holistic conceptual understanding, and relevant to the context of students' daily lives.

Abstract

This study aims to analyze students’ learning needs in electrochemistry learning based on the Culturally Responsive Transformative Teaching (CRTT) framework. CRTT is a pedagogical approach that integrates students’ cultural backgrounds and lived experiences into learning to make it more inclusive and meaningful. The research employed a descriptive quantitative method complemented by qualitative data from open responses. A total of 32 Grade XII MIPA students from UM Laboratory High School participated in the study. Data were collected through a validated questionnaire consisting of 15 closed and 5 open-ended items. The results show that 64% of students have a moderate understanding of electrochemistry, with the most difficult subtopics being Galvanic and Electrolysis Cells. Students expressed strong interest (80%) in contextual learning through simple and eco-friendly edukits, as well as enthusiasm for integrating local culture such as keris plating and natural electrolytes from plants. These findings emphasize the importance of developing CRTT-based learning tools that connect chemical concepts with students’ cultural realities to foster deeper conceptual understanding, engagement, and transformative learning experiences.
