This study examined the effect of the SB-CPBL on Jordanian 8th-grade students' attitude towards science. A quantitative quasi-experimental design with a non-equivalent control group was employed in this study. 120 8th-graders, divided into two groups, were involved in this study. Two groups (60 students, 30 males, and 30 females) were designated…

This study aimed to examine the effect of the problem-based learning (PBL) on science attitudes of middle school students from low socio-economic status families. For this purpose, two intact classes of the same teacher were randomly assigned as experimental and control groups. In the unit of genetics, the experimental group was taught by PBL…

Most of the previous problem-based learning (PBL) studies have been conducted with gifted or regular education students and have shown successes. However, little research on PBL exists for disadvantaged middle school students, especially students who are considered to be at risk of failing academically. In this study, we examined the use of a…

The present study was an attempt to investigate the effect of Problem-Based Learning (PBL), Predict, Observe, Explain (POE), and the combination of both (PBLPOE) on students' critical thinking skills and scientific attitudes in Biology. A pretest-posttest nonequivalent control group design was employed in this study and 132 tenth-grade students…

The purpose of this study is to determine the effects of the scenario-based STEM project design process on pre-service science teachers' perceptions of 21st-century skills, competencies, integrative STEM teaching intentions, and STEM attitude. In the study, a pretest-posttest quasi-experimental design, which does not contain a control group, was…

In 2016, the Program for International Student Assessment (PISA) showed that approximately 44.4% of students in Turkey obtained very low grades when their scientific knowledge was evaluated. In addition, the vast majority of students were shown to have no knowledge of basic scientific terms or concepts. Science teachers play a significant role in…

This study was designed to explore the effects of problem-based learning (PBL) strategies on the attitudes of female senior high school students toward integrated knowledge learning in science, technology, engineering, and mathematics (STEM). Content analysis and focus group methods were adopted as the research processes. Data and information…

The purpose of this paper is to investigate the impact of problem-based learning (PBL) on freshmen engineering students' beliefs about physics and physics learning (referred to as epistemological beliefs) and conceptual understanding of physics. The multiple-choice test of energy and momentum concepts and the Colorado learning attitudes about…

This study investigated the effects of problem-based learning on students' beliefs about physics and physics learning and conceptual understanding of Newtonian mechanics. The study further examines the relationship between students' beliefs about physics and their conceptual understanding of mechanics concepts. Participants were 124 Turkish…
