Development of E-Modules to Improve Scientific Explanation Skills in Science Learning for Junior High School Students
Get PDFScientific explanation skill is one of the essential skills for students in science learning today. Scientific explanation is a reasoning skill that relates claims, evidence, and reasoning. Students can understand, articulate, and explain scientific phenomena accompanied by evidence and reasoning with scientific explanation skills. However, in reality, students are still lacking in scientific explanation skills. In an effort to improve scientific explanation skills, teaching material is needed to be developed in the form of e-modules. The use of e-modules in learning is expected to train students' thinking skills, one of which is scientific explanation skills. This study aims to determine the validity, practicality, and effectiveness of e-modules to improve the scientific explanation skills of junior high school students in science learning. The development of the e-module is carried out in three stages, namely preliminary research, prototyping stage, and assessment phase. The results showed that e-modules were included in the valid, practical, and effective categories. Thus, the e-module can be used and applied to develop science learning outcomes and scientific explanation skills.Keywords: scientific explanation skill, e-module, science learning.DOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp34-4

ICARE-U Learning Model to Improve Critical Thinking Skills of High School Students in Indonesia
Get PDFCritical thinking is one of the skills that are widely trained in the field of natural science studies. The study was conducted at a high school in the city of Padang to determine the effectiveness of ICARE-U learning (Introduction, Connection, Application, Reflection, Extension and Utility) on students' critical thinking skills in the matter of effort and energy. The research method used is pre-experimental with one group pretest posttest design. The research sample consisted of one class 10 high school as many as 31 people. Critical thinking skills are viewed from 5 aspects, namely elementary clarification, basic support, inference, advanced clarification, strategy and tactics. Based on the results of the n-gain on students' critical thinking skills with the ICARE-U learning model, a score of 0.4 was obtained. A score of 0.4 means that students' critical thinking skills before and after being given treatment have increased in the moderate category. Reviewing the critical thinking skills aspect, it is known that the advanced clarification aspect is still experiencing a low increase. Based on the results of hypothesis testing, it was found that the ICARE-U learning model was effectively used to improve students' critical thinking skills in the matter of effort and energy.
