Effectiveness and Practicality of Wetland Ethnoscience E-Magazine Based on the Scientific Critical Thinking (SCT) Model for Improve Critical Thinking Skills

This research is a research and development (R&D) study using the ADDIE model, which aims to determine the effectiveness and practicality of the SCT Model-Based Wetland Ethnoscience E-Magazine on students’ critical thinking skills in stoichiometry learning. Data collection techniques use test instruments, response questionnaires, learning implementation sheets, and the teacher’s ability to use e-magazines to test effectiveness and practicality. The effectiveness test is carried out using test instruments for critical thinking skills. Meanwhile, practicality tests were conducted on teachers’ and students’ responses to e-magazine products, observation sheets on learning implementation, and teachers’ ability to use e-magazines. The results of research on critical thinking skills in students at SMAN 3 Banjarmasin, SMAN 7 Banjarmasin, and SMAN 12 Banjarmasin showed an average n-gain value of 0.80; 0.81 and 0.80 in the high category, so it is effective for improving students’ critical thinking skills. The influence test results using the Wilcoxon test show an influence or improvement in students’ thinking skills using the significance of the Wetland Ethnoscience E-Magazine Based on the Scientific Critical Thinking (SCT) Model. The results of the difference test (Kruskall Wallis) show that there is no difference (consistency) in the increase in students’ critical thinking skills after using the Wetland Ethnoscience E-Magazine Based on the Scientific Critical Thinking (SCT) Model for each school. The results of the teacher response questionnaire regarding the use of E-magazine showed a mean value of 4.67. The response results from students at SMAN 3 Banjarmasin, SMAN Banjarmasin, and SMAN 12 Banjarmasin showed a mean of 4.31, 4.33, and 4.34 in the very good category. The results of teachers’ ability to use E-magazines at SMAN 3 Banjarmasin, SMAN 7 Banjarmasin, and SMAN 12 Banjarmasin showed scores of 4.63, respectively, 4.65 and 4.64. Learning implementation results with a score of 4.57, 4.60, and 4.58. Based on these results, it can be said that the use of the SCT Model-Based Wetland Ethnoscience E-Magazine is effective and practical in the learning process for student’s critical thinking skills.
