This study aimed to juxtapose the impacts of the Problem-Based Learning (PBL) methodology implemented within a three-dimensional (3D) virtual environment against PBL in a conventional face-to-face setting, along with a control group, on students' learning performance, conceptual comprehension, and spatial aptitude. The investigation concentrated…

This study aimed at analyzing the impact of problem-based learning (PBL) in improving physics students' conceptual understanding of mechanical waves. This study used a quasiexperimental, pretest-post-test control group design with PBL instruction as a teaching intervention. The participants of this study were 239 physics students from 19 secondary…

When teaching STEM courses, it is important to introduce state-of-the-art techniques. Students need to learn how to conduct experiments, analyse data and choose the most effective approaches to address meaningful situations. Here we present the assessment of the implementation of a structured inquiry-based activity aimed at teaching students about…

This study aimed to assess the impact of problem-based learning (PBL) on students' achievement in mechanical waves among secondary schools in South Western Uganda. Four hundred and nineteen students (419) from 19 schools were involved in this study. A quasi-experimental research method was employed through Solomon's four-group design. Form six…

The limited time allocation for lectures in the classroom is an obstacle to presenting student-centered learning. This is one of the factors that prospective physics teacher students experience conceptual difficulties, especially in crystal structure material. So the purpose of this study was to determine the effectiveness of the problem flipped…

This study aims to reveal the effectiveness of the problem-based learning (PBL) model in teaching the concepts of heat, temperature and pressure, as well as the effect of the activities on the development of scientific process skills. For this purpose, the change in the academic achievement levels of the students constituting the sampling group…

Regarding 21st-century learning, scientific literacy is an important competency which must be owned by students. Nevertheless, scientific literacy of Indonesian students has been recognized in low level. This study aimed to describe students' scientific literacy in Bryophyta topic using problem-based learning. This Classroom Action Research (CAR)…

This paper tells about the mental model of prospective scholars on the topic of temperature and heat. The purpose of this research is to improve students' mental model by using problem based learning (PBL) model. The number of samples in the study amounted to 72 students with two different classes. The results of the study showed that, (1) the…

The aim of this study is to compare the effects of using different teaching methods in "Cell and Division" and "Force and Energy" units on students' engagement in the lesson and scientific process skills. In each of the five randomly selected groups, the lessons were taught with Multiple Intelligence, Problem Based Learning,…

A mental model (MM) is an internal representation of students' conceptual understanding. Currently, students have still had difficulties in explaining the physical state of elasticity of solid materials, at submicroscopic level. These difficulties call for this research. Through a mixed method, the study aimed to reveal the development and…

The study aimed to investigate the effectiveness of problem-based learning (PBL) approach in enhancing the problem solving skills in Chemistry of Grade 9 students in a public high school in the Philippines. The level of problem solving skills of the students in the non-PBL and PBL group before and after their exposure to non-PBL and PBL approaches…

This case study explores how a science teacher adopted knowledge building and learning analytics to support a class of primary five students to collaboratively inquire and learn about electricity. Specifically, we aim to understand how the teacher implemented a lesson design guided by knowledge building principles of idea improvement and community…

Research has highlighted difficulties experienced by students when studying quantum physics in introductory courses. In this paper, we present a teaching and learning sequence (TLS) aiming at introducing a quantum model of emission and absorption of radiation and we assess its impact on the students' learning about atomic spectra. The TLS has been…

Genetics can be a difficult topic to teach and learn in a traditional classroom. The objective of this qualitative classroom action research was to examine the effectiveness of a blend of problem-based learning (PBL) with scientific argumentation to improve student understanding of basic genetics. The research participants were grade 9 Bhutanese…

This paper describes the problem-solving studio (PSS) learning environment. PSS was designed to teach students how to solve difficult analytical engineering problems without resorting to rote memorization of algorithms, while at the same time developing their deep conceptual understanding of the course topics. There are several key features of…
