One of the skills needed in the 21st century is critical thinking skills that need to be developed for secondary school students. Currently, upper-secondary students' critical thinking skills are still low. To overcome the problem, websitebased E-module learning media was developed using a STEM approach with a Problem-Based Contextual Learning…

The aim of the research was to know the effect of implementation of problem-based learning model on students' physics achievement and critical thinking. The research was a quasi-experimental using a pre-test-post-test control group design. It was conducted at a state senior high school in Indonesia. The data were collected by a students' physics…

Critical thinking skills are one of the 21st century skills that are effectively trained by using the OR-IPA and Problem Based Learning (PBL) Model, therefore this research aims to compare the effectiveness of both. Research design used True Experiment with Randomized Subject Control-group Pre-test and Post-test with 94 pre-service physics…

This research was conducted to evaluate the effects of Problem-based Learning (PBL) with Thinking Maps (TM) teaching method (PBL-TM) on Fifth Graders' science critical thinking. The critical thinking skills evaluated were Comparing and Contrasting, Sequencing, and Identifying Cause and Effect in physical science. A quasi-experimental pre-test and…
