The ability to think critically in the 21st century is a skill that must be possessed by every individual. This study, uses a UbD-based problem-based learning model with a conventional learning model to see which learning model has more influence on the critical thinking ability of grade IV students in science subjects. The UbD approach was chosen…

This study compares direct instruction to two constructivist approaches, namely experimentation and problem-based learning, in fifth-grade science learning in Hong Kong. Constructivist instructional approaches, contrary to direct instruction, stress on students' active role in constructing knowledge in learning. Experimentation and problem-based…

The aim of this study is to examine the effect of the science module which was designed using the problem-based learning method on the basis of the Integrated Curriculum Model and applied in the blended learning environment on the scientific reasoning and scientific process skills of gifted students. The study was carried out with 9 gifted 5th…

This study aims to investigate the effect of the problem-based learning method supported by experiments on the inquiry learning skills of secondary school students and their reflective thinking skills for problem-solving. This research uses a quasi-experimental design with a pretest-posttest control group. This study consists of 21 students in the…

This study examined how 465 socioeconomically disadvantaged middle school students used a multimedia-enriched problem-based learning (PBL) program. Using a mixed-methods design, we investigated the impact of PBL on students' performance, and relationship among students' self-efficacy, attitude toward science, and performance. The findings showed…

Problem-based learning (PBL) involves students solving a problem with multiple solutions over time, like scientists in real-world contexts. This fourth-grade PBL unit had students become part of an endeavor to help their state of Virginia become energy independent. It conceptualized energy independence as becoming self-sufficient for energy…

This study aimed to present a module related to the use of concept cartoons integrated into problem-based learning (PBL) method in science lessons. As part of the study, concept cartoons were developed based on scenarios dealing with daily life situations. A module was designed using these concept cartoons. The module focused on the topic…

This mixed-method study introduced an adaptive scaffolding system to support middle school science problem-based learning (PBL) activities. 298 6th-graders were grouped into three conditions, which are the adaptive scaffolding group, the non-adaptive scaffolding group, and a control group that did not receive any scaffoldings. Results showed that…

This article describes an 8-10 week problem-based learning unit for fifth graders that introduced them to the facts underlying global climate change. This unit was inspired by the lack of awareness in our national population around this clear threat to our global ecosystem and takes on this goal: to provide students (our future advocates and…

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…

Computer science (CS) and computational thinking (a problem-solving process used by computer scientists) teach students design, logical reasoning, and problem solving--skills that are valuable in life and in any career. Computational thinking (CT) concepts such as decomposition teach students how to break down and tackle a large complex problem.…

This embedded mixed method study used a randomised controlled? trial design to examine two cohorts of upper (grades 4-6) elementary teachers' classroom implementation of nature of science (NOS) instruction following their participation in a statewide professional development (PD). The treatment group (n = 145) was compared to a control group (n =…

Decision matrices are valuable engineering tools. They allow engineers to objectively examine solution options. Decision matrices can be incorporated in K-12 classrooms to support authentic engineering instruction. In this article we provide examples of how decision matrices have been incorporated into 6th and 7th grade classrooms as part of an…

This research was conducted to evaluate the effects of Problem-based Learning (PBL) with Thinking Maps (TM) teaching method (PBL-TM) on Fifth Graders' science critical thinking. The critical thinking skills evaluated were Comparing and Contrasting, Sequencing, and Identifying Cause and Effect in physical science. A quasi-experimental pre-test and…

Problem based learning, in which events from daily life are presented as interesting scenarios, is one of the active learning approaches that encourages students to self-direct learning. Problem based learning, generally used in higher education, requires students to use high end thinking skills in learning environments. In order to use…
