This study investigates the effect of the use of teachers’ Lecture models combined with cooperative learning methods to improve students’ problem-solving skills in physics compare with the control group who were not exposed to the lecture model combined with cooperative learning methods from effect size value. The research method was a quasi-experimental research. The sample consisted of 33 students of 10th grade in middle schools (senior high school), SMAN 1 Sungai Penuh, Jambi Province where they ware learn at work and energy concept. Students' achievements, as well as their problem-solving skills of work and energy concept were assessed by pretest-posttest with an essay test. The results showed that the experimental group’s learning process has a high effect size value to problem-solving skills more than control group learning process. That shows the lecture model combined with cooperative learning method more effective than lecture model.

This research aims to development a REACT-based e-worksheet that is feasible to use to stimulate the critical thinking, creativity, collaboration, communication (4C) skills and determine student response. The challenges of a dynamic era require students to have a 4C skills set critical thinking and problem-solving skills; creativity and innovation; communication; and collaboration. One of the tools that can be used in online learning to achieve this goal is to use the electronic Student Worksheet (E-Worksheet) which includes the student's 4C skill values with REACT strategies: Relating, Experiencing, Applying, Cooperating, and Transferring. The research chooses one of the topics in chemistry, which is introduction to chemistry and laboratories. This REACT-based e-worksheet was developed using the ADDIE development model which consists of five stages those are analysis, design, development, implementation, and evaluation. In addition, the study used a sample of 10 students of mathematic and natural science 12th grade MAN 4 Tangerang. Based on the results of validation and student response questionnaires, REACT-based e-worksheet to stimulate students' 4C skills was declared valid and obtained an average percentage of 91.8% with very good criteria.
