Marble, formed by the metamorphism of limestone, is commonly used in the construction industry and sculpting. The mineral in marble is either calcite [CaCO[subscript 3]] or dolomite [CaMg(CO[subscript 3])[subscript 2]] or sometimes both. The pure white Carrara marble from Italy was made a household name by Michelangelo, the famous sculptor of the…

Creative thinking skills are recognised 21 century skills. This study aimed to determine whether students' creative thinking skills in biochemistry courses are improved through scaffolding-based problem-based learning. The study employed a mixed methods approach with a sample of 113 chemistry education programme students at Jambi University. An…

This study aimed to describe the differences in students' creative thinking skills in a problem-based learning model with scaffolding in the biochemistry course. This study was designed using a quantitative explanatory research design with a sample of 113 students of the Jambi University Chemistry Education Study Program. In this study, the…

Success in problem-based learning requires both strong information literacy to search for, evaluate, and use information effectively, and argumentation skills to generate coherent arguments. This study investigated the positive and negative effects of computer-based scaffolding to support high-school credit recovery students' information literacy…

This paper describes a comprehensive review of 31 quasi or experimental research studies from the past decade on the effect of PhET simulations on students' conceptual understanding of physics. Two questions guided the review: (i) To what extent do PhET simulations enhance students' conceptual understanding of physics? (ii) What are the best ways…

The need for shifting the expository laboratory instruction style to inquiry-based approaches is widely acknowledged. Problem-based learning (PBL), one of the inquiry-based approaches, advocates students' self-directed learning. The literature indicates that scaffolding students' independent learning is necessary for a PBL environment. In our…

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…

Collaborative inquiry learning affords educators a context within which to support understanding of scientific practices, disciplinary core ideas, and crosscutting concepts. One approach to supporting collaborative science inquiry is through problem-based learning (PBL). However, there are two key challenges in scaffolding collaborative inquiry…

In this study, we investigated how high school credit recovery students worked in small groups and used computer-based scaffolds to conduct scientific inquiry in a problem-based learning unit centered on water quality. We examined how students searched for and evaluated information from different sources, and used evidence to support their claims.…

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…

Argumentation is central to instruction centered on socio-scientific issues (Sadler & Donnelly in "International Journal of Science Education," 28(12), 1463-1488, 2006. doi: 10.1080/09500690600708717). Teachers can play a big role in helping students engage in argumentation and solve authentic scientific problems. To do so, they need…

Student populations are diverse such that different types of learners struggle with traditional didactic instruction. Problem-based learning has existed for several decades, but there is still controversy regarding the optimal mode of instruction to ensure success at all levels of students' past achievement. The present study addressed this…

Research on learning and instruction of science has shown that learning environments applied in preschool and primary school rarely makes use of structured learning materials in problem-based environments although these are decisive quality features for promoting conceptual change and scientific reasoning within early science learning. We thus…

Problem-based learning (PBL) and inquiry learning (IL) employ extensive scaffolding that results in cognitive load reduction and allows students to learn in complex domains. Hybrid teacher professional development models (PDM) using 21st century social collaboration tools embedding PBL and IL shows promise as a systemic approach for increasing…

Objective: To develop a totally online reality-based course that engages students and enables the development of enhanced teamwork and report-writing skills. Setting: Outbreaks of infectious diseases impacts upon commerce, trade and tourism as well as placing strains on healthcare systems. A general course introducing university students to…
