Abstract

Critical thinking skills are one of the essential thinking skills mastered in the 21st century for the progress of a nation. They can help a person to solve problems by interpreting, analyzing, evaluating, and inferring. Self-efficacy is a person's belief in his ability to solve problems. The ability to think critically is related to self-efficacy. The PjBL-STEAM model is one of the alternatives that seek to improve student’s critical thinking and self-efficacy skills. The wetland context referred to in this study uses a solution of fruits that can live in wetlands as one of the learning media on electrolyte and nonelectrolyte solution materials. This study aims to examine the improvement of critical thinking and self-efficacy of students through the use of the PjBL-STEAM learning model in wetland contexts by comparing pretest and posttest values. This research model is quasi-experimental with a one-group pretest-postest research design. This study was conducted at SMAN 3 Barabai with a study population of class X MIA, and the sample taken purposively was 25 students of class X MIA 3. Data collection using tests and questionnaires. Data analysis was carried out by comparing pretest and posttest values. The results showed that the PjBL-STEAM learning model in the wetland context could improve the critical thinking skills and self-efficacy of students with an N-gain value of critical thinking ability of 0.58 (moderate category) and N-gain self-efficacy of 0.75 (high category). In other words, using PjBL-STEAM in wetland contexts is stated to be effective for improving students' critical thinking skills and self-efficacy.

Abstract

The low problem-solving ability of chemistry students in solving contextual problems is related to their low conceptual understanding and environmental literacy. Based on these problems, this study aims to improve problem-solving abilities and conceptual understanding through the development of a biodiesel e-module with a valid, practical, and effective STEAM Web Based Blended Learning (STEAM WBBL) approach. This study uses the ADDIE model for research and development. This study was conducted on 40 Chemistry Education students of the Faculty of Teacher Training and Education. Data collection techniques used questionnaires and test instruments for problem-solving abilities, conceptual understanding, and environmental literacy. The effectiveness analysis technique used a written test in the form of problem-solving ability and conceptual understanding test instruments. Based on the validity test, the developed biodiesel e-module was declared valid, very practical, and effective in improving students' problem-solving abilities, conceptual understanding, and environmental literacy with N-gain values of 0.75, 0.73, and 0.68, respectively. The biodiesel e-module application with the STEAM WBBL approach is suitable for use as a teaching material.

Abstract

The main challenge faced by the Karang Bunga Village community is the low price of Siam Banjar oranges during the harvest season, which negatively affects the farmers' economy. To address this issue, it is necessary to diversify processed citrus products as part of the Citrus House business unit managed by the Village-Owned Enterprise (BUMDes) "Berkah Bersama." This Community Service activity utilized the “service learning” method to train students in leadership skills through hands-on community empowerment efforts. One of the main focuses of the community service activity was developing an ice cream product made from Siam Banjar oranges, covering aspects such as production, packaging, and marketing. The results of the community service activity showed an increase in community skills and knowledge, with an average score of 2.99, indicating that the level of knowledge and skills falls within the "good" category. However, there are still challenges in the areas of packaging and marketing. The average score for the evaluation of the activity implementation was 3.42 (good category), and the average score for the resulting ice cream product was 3.13 (also in the good category). This activity is expected to improve product quality, expand market reach, and ultimately have a positive impact on the income of the village community.

Abstract

This research and development (R&D) study aims to assess the validity, practicality, and effectiveness of the Android-based E-Module for Biochemistry Practicum developed using Construct 2. The development of this E-Module is designed to improve students' creative thinking skills. This study adopted the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The research sample consisted of 27 students from the Chemistry Education Study Program, FKIP ULM Banjarmasin, Class of 2019, Class A1. The data collection methods used were test and non-test methods. The research instruments used for data collection in this analysis include essay assessments (pre-test and post-test) and questionnaires. Data analysis was conducted to measure three main aspects: validity, practicality, and effectiveness. The results showed that the developed E-Module product met all criteria: (1) Highly Valid, based on expert assessment of general aspects, content, language, and media design; (2) Highly Practical, as evidenced by the results of individual and small group trials, student and teaching assistant response questionnaires, and observation sheets; (3) Highly Effective, as indicated by the N-gain scores for students' creative thinking skills, which fall into the High category. Overall, this Android-based Project-Based Learning (PjBL) Biochemistry Practical E-Module has proven to be suitable and effective as a learning medium to enhance students' creative thinking skills.

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%.
