The Effectiveness of Natural Science Handouts Based on Critical Thinking Skills on the Diversity of Living Things: Keefektifan Handout IPA Berbasis Keterampilan Berpikir Kritis pada Materi Keanekaragaman Makhluk Hidup
Get PDFThe development of critical thinking skills is one of the key factors to face the opportunities and challenges of life in the industrial era 4.0. However, this skill has not been trained properly. Therefore, the purpose of writing this paper is to analyze the effectiveness of science handouts on the material diversity of living things to improve students' critical thinking skills. This study uses formative evaluation with Tessmer Model, which is limited to small group and field tests. The trial used a one group pretest and posttest design, for a small group test on 12 students and a field test on 20 class VIII students of SMPN 1 Sungai Durian. Collecting data through critical thinking tests and interviews. The results of the research on the small group and field tests showed: (1) students' skills in interpretation, analysis, explanation, evaluation, and inference were initially low to moderate; and (2) students' critical thinking skills increased significantly at = 5%, with n-gain in the moderate criteria. Thus, the science handout based on critical thinking skills that was developed is effectively used in science learning

This EduKIT provide activities so students can have experiences to string and think solution about any problems integrated by technology as demanded of Education in 21st century. This research using ADDIE model which is only limited to the development stage. At each stage, an evaluation process is carried out to produce the maximum product. To measure the validity and feasibility of the media, an instrument in the form of a questionnaire was used. Quantitative data is obtained from the score given by the validator against each criterion and indicator on the validation sheet. While the qualitative data is obtained from the advice given by the validator. The result shows that the EduKIT was highly valid to use with the percentage 98% and 99% for validation media and content validity respectively. This assessment was tested on two science education experts. While the result for the readability test by five teachers was 96% and 91% from ten junior students. Those percentage (>90%) show very practical and highly valid to be used. Based on the results of the validation and readibility test, it can be concluded that EduKIT was valid and practical, so it is suitable for students to use as a learning medium to practice problem solving skills in preparing the 21st century generation
The Effectiveness of SW (Student Worksheets) Based on STEM (Science, Technology, Engineering, Mathematics) to Train Students' Creative Thinking Skills: Efektivitas Lembar Kerja Peserta Didik Berbasis STEM (Science, Technology, Engineering, Mathematics) Untuk Melatihkan Keterampilan Berpikir Kreatif Peserta Didik
Get PDFExisting learning has not fully facilitated 4C (critical thinking, communication, collaboration, and creativity) skills and there are obstacles for students to encounter in studying biology, especially the material about plant tissue. It happens due to various limitations in achieving basic competency skills. One of the learning approaches that can be used to support 4C skills is the STEM approach which is supported by student worksheets (SW) to guide the learning process. The purpose of this study was to measure the effectiveness of STEM-based SW to train students' creative thinking skills. The research method used is descriptive quantitative and qualitative with one group pre-test and post-test design. The research subjects were 21 students of XI grades at SMAK St.Hendrikus. Data analysis of the N-Gain test of creative thinking skills obtained an average N-gain of 0.7 with a medium category. The N-Gain analysis of creative thinking skills using the T-Test with a sig. (2-tailed) value of 0.000 indicates that STEM-based worksheets are effective in training students' creative thinking skills
