Student's critical thinking skills that are currently still low are important to develop because they affect the way students think in solving problems. The problem-based learning model with the inquiry method used to help improve student's critical thinking skills. The iSpring learning media used can help students understand the material. The…

Critical thinking skills are needed to face the challenges of living in the 21st century. Education must be able to foster students' critical thinking and enable them to think independently. This study aims to investigate the development of students' critical thinking skills during the learning process using an e-module based on problem-based…

Fostering students' critical thinking skills is an urgent issue that requires immediate attention. One viable solution to address this is the implementation of project-oriented problem-based learning (POPBL) through the SR-STEM project. This research aims to describe the implementation, effectiveness, and student perception of the POPBL model…

Education in the 21st century has experienced many advances that are adjusted to the demands of the times. Thinking skills are in high demand in the 21st century, especially critical thinking and creative thinking skills for students. This study aims to determine the effectiveness of POPBL model learning in improving critical and creative thinking…

This study aims to test the effectiveness of using environment-oriented e-books based on Problem-Based Learning (PBL) to empower problem-solving skills. The research design used is a Nonrandomized Control Group, Pretest-Posttest Design. The study used a quasi-experimental method with a 2 x 2 factorial design. The research sample was 70, grade X…

This study aimed at testing the effectiveness of an e-module based on ProblemBased Learning combined with Socratic Dialogue on the topic of environmental change in improving school students' critical thinking skills. This research was a quasi-experimental study and used a non-randomised control group, pre-test/posttest design. The sampling…

This study investigated the effectiveness of the orientation, identify, discussion, decision, and engage in behavior (OIDDE) learning model in enhancing biology learning outcomes, critical thinking, ethical attitudes, and engagement among high school students in Indonesia. Employing a quasi-experimental design with pre- and post-tests, the…

Merdeka Curriculum, the latest curriculum implemented in Indonesia by the Ministry of Education and Culture since 2021, faces obstacles in its implementation, including in history subject. A key obstacle history teachers encounter is the lack of alternative learning strategies designed to develop students' historical thinking skills. This study…

This research aimed to examine the effects of problem-based learning with character emphasis and naturalist intelligence on the students' critical thinking skills and curiosity. This study was conducted at Islamic Senior High School in Mataram and it employed 3x2 treatment by level design. Three treatments; the problem-based learning with…

Climate change put most species' survival in danger because it substantially affects the climate in which the species live, the quality of the water they drink, as well as the temperature of the air or water. When climate change increases the temperature of the climate, excessive evaporation occurs in lands, lakes, seas, and oceans. Our purpose in…

Students in Indonesia still have the low level of scientific argumentation skills. This study purposed to examine the impact of Problem-based Learning (PBL) with Argument Mapping and Online Laboratory in improving the scientific argumentation skill. It describes the significance of the differences between participants who learn through PBL, PBL…

The industrial revolution era 4.0 has now become a major topic in every country. Various sectors respond quickly to this problem, including education. In response to this, there are several aspects of skills that students must master. One of them is problem-solving skills. One of the aspects that influence the students' problem-solving skills is…

A more motivating way of introducing students to probability theory is through real-world problems. Since heuristics play an important role in our probabilistic judgement, knowing how to avoid incorrect probabilistic reasoning, which leads to several biases, could help students to develop more critical thinking skills. In this paper, we present a…

The previous research result showed that the learning model based on the investigation could increase the students' critical thinking skills. The aim of this research was to measure the effectiveness of the using of problem-based learning model to increase the students' critical thinking skills. The research design was quasi-experiment by using…

Purpose: This study aimed to investigate the potential effects of problem-based learning (PBL), predict observe explain (POE), and PBLPOE on students' problem-solving skills and self-efficacy in Biology. This research is based on various facts that problem-solving skills and self-efficacy of Indonesian students in biology subjects are still low.…
