How do scientists make inferences for something they cannot directly observe? The Black Box approach seems ideal to help students understand how scientists work. Black Boxes are sealed units; their interior is not accessible. The effort to determine their possible content (internal structure) demands successive modifications in hypothesis,…

Additive manufacturing (AM) is projected to require 60,000 jobs in the UK by 2025, but there are a series of barriers to the industrial application. One of the most problematic is non-comprehensive knowledge in design for AM (DfAM). This study aims to test the effect of two undergraduate DfAM teaching approaches. A visual and audial approach…

Student science proficiency development demands sustainable and coherent learning environment support. Scholars argue that project-based learning (PBL) is an efficient approach to promoting student science learning, compared to conventional instructions. Yet, few studies have delved into the learning process to explore how a coherent PBL system…

This study aims to identify publication trends and recommendations for problem-based science learning research in elementary schools. We used a mixed-methods research design in which descriptive, qualitative, and bibliometric analyses were used to look at the data. We selected the sample by using the purposive sampling technique. Secondary data…

This study aims to examine the effect of the Challenge based learning model on Critical thinking skills and learning outcomes in History learning. This research type is a quasi-experimental design with a Pretest-Posttest Non-Equivalent Control Group. The population were students of class X IPA 1, X IPA 2, X IPA 3, X IPA 4 and X IPA 5 at SMA…

The primary goals of this research were to investigate the development of computational thinking (CT) skills among elementary students and to identify areas for improvement in their CT practices. Empirical investigations, accomplished in a learner-centered, problem-based learning curriculum for sixth-graders, sought to examine student proficiency…

This study explores pre-service geography teachers' assessment of the impact of hard and soft scaffolds used in problem-based learning on their own learning. Respondents had to complete a "Scaffolds in geography problem-based learning" instrument after the problem-based learning intervention. The respondents could also elaborate on the…

In this article, we explore Terry Wood's participation in the Purdue Problem-Centered Mathematics Curriculum Project, along with the rich and enduring personal and professional friendships that she built with the classroom teachers who were so important to the project. We highlight connections between these working relationships and the research…

In response to decreasing motivation in high school math classrooms, teachers are transforming classrooms with various instructional techniques. Traditional math instruction relies on direct instruction and memorization of content, processes, and skills. Teachers are transitioning to more constructivist student-led approaches. Utilizing multiple…

A tutor and a student together propose a model for integrated student and staff engagement that concentrates on developing students' core abilities. They build upon their respective experiences of self-managed problem-based learning and of the purposeful promotion of core abilities. They explore the potential of collaborative interaction between…

Investigating the optical properties of various chemical compounds using UV-vis spectrophotometers is an essential part of education in chemistry. However, commercial spectrophotometers are usually treated as "magic black boxes", where the dominant majority of optical elements are hidden "under the hood". This often limits…

Path analysis is used to provide estimates of the magnitude and significance of hypothesized causal connections among sets of variables displayed using path diagrams. It is an extension of multiple regression analysis and holds strength as a methodology as it allows researchers to assess both direct and indirect effects of multiple independent…

This study aims to determine whether there was differences effect in improving student's critical thinking skills (1) between students who get Problem-based Learning, Mathematical Problem Posing, and conventional learning, and (2) based on gender differences. This study used a quantitative method with the pre-test-posttest two treatment design.…

This study aims to examine the effect of Problem Based Learning learning strategies, cognitive styles, and their interaction on students' problem-solving ability in social studies subjects. The type of this research is a quasi-experiment with nonequivalent control group design. The number of samples used was 120 students consisting of 60 students…

The study aims to compare the effectiveness of Guided Inquiry Learning (GIL) and Problem-Based Learning (PBL) model. A number of prior studies have implemented the GIL model for a limited area such as science. Similar to the PBL learning design, the previous studies that highlighted the application of GIL model was commonly targeted to find out…
