Problem-based STEM education can be defined as the solving of real-life problems by using science, technology, engineering, and mathematics disciplines. This study aims to determine the effect of problem-based STEM practices on pre-service teachers' conceptual understanding. The pre-service science teachers participated in 12 weeks of STEM…

Ergonomics courses typically cover a range of topics related to the design and organization of workplaces to optimize human performance and well-being while minimizing injury risk and discomfort. This study introduces the PBL application steps to attract attention to the importance of noise not only in workplaces but also in daily life. The…

The present study was to teach metabolic syndrome (MetS) disease through a scenario developed according to the problem-based learning (PBL) approach in the biochemistry class. The study was designed as a single group pre-test and post-test research. The study group consisted of first-year students (N = 183) from the nursing department within the…

The purpose of this action research was to enable university students to learn about children's rights with the scenarios developed based on the problem-based learning (PBL) approach. In this context, three scenarios related to daily life have been developed on the right to participate, the right to education, the right to rest, leisure, play, and…

The purpose of this mixed-methods sequential explanatory study is two-fold. It is intended first, to determine the effect of problem-based learning (PBL) on problem-solving skills, and second, to reveal student opinions regarding PBL. A quasi-experimental design with a pre-test and post-test control group was preferred in the quantitative…

The purpose of this study is to investigate the effect of argumentation, during the hypothetico-deductive reasoning (HDR) process in the problem-based learning (PBL) approach, on nursing students' achievements and to determine the argumentation levels in the biochemistry course on the topic of endocrine and nervous systems. The participants…

This multiple case study aims to describe how Turkish students in English Language Teaching (ELT) and Electrical-Electronics Engineering Program (EEP) conceive of Problem-based Learning (PBL), and how they experience their studies within a PBL-oriented curriculum. With the inclusion of these two cases into the study, the rationale is to represent…

In this study, the instructional design process in three-dimensional multi-user virtual environments (3D MUVEs) based on a problem-based learning approach was examined and authentic design experiences were shared. Besides, a design model was proposed to guide people who want to design these 3D MUVEs and to use these environments for educational…

The purpose of this research is to determine the conceptual understanding of pre-service science teachers about "Colligative properties", which are aimed to be taught within the scope of Chemistry-II course, within the framework of the argumentation-supported problem based learning (AS-PBL) method. The study, in which 24 pre-service…

This study aims to examine the effects of argumentation-supported problem-based learning (AS-PBL) carried out in the Chemistry-II laboratory course on the conceptual understanding of prospective science teachers about "Chemical equilibrium and Le-Chatelier's principle". The prospective teachers' answers were analyzed using content…

The literature widely reports that pre-service teachers repeatedly demonstrate inadequate argumentation skills. Through a mixed-methods research approach, this study investigated the effectiveness of a holistic online scaffolding design for guiding the development of pre-service teachers' argumentation skills. Participants were randomly assigned…

The aim of this study is to determine the effectiveness of the instruction process through the use of the PBFC model within the scope of the CN&C course. The evaluation of the PBFC process was made with the qualitative data obtained from the participants within the scope of CoI. Within the scope of cognitive presence, the participants firstly…

The purpose of this study is to determine the curriculum design approach preferences of pre-service teachers who have been receiving pedagogical training. The sample of the study consists of 138 pre-services teachers who took the curriculum development course in pedagogical formation education. In the study, "Teachers' Curriculum Design…

This research investigated the effect of problem-based learning (PBL) for the topic of "energy metabolism" in a biochemistry course on the academic achievements of students studying in the healthcare field in a nursing department. The study had a one-group pre-test and post-test research design. The study group consisted of first-year…

This study aimed to determine the views of pre-service science teachers about STEM education. A two-hour Arduino based STEM learning activity was conducted for fifteen pre-service science teachers. Afterwards, the views of the participants were investigated by conducting an online survey consisting of open-ended questions. Finally, the obtained…
