This article systematically reviews the pedagogical approaches adopted in high school chemistry education with the aim of highlighting the most effective evidence-based instructional practices reported in the literature. For this, a meta-analysis of 35 pedagogical approaches is analyzed, and their effect sizes (Cohen's d) are compared in terms of…

One way to preserve culture in education is through ethnoscience-based learning, especially in chemical materials linked to various fields of science in life, including social and cultural. Ethnoscience is a process of reconstructing indigenous science knowledge with scientific science. This research aims to explore trends in ethnoscience-based…

The aim of this article is to examine research on inquiry-based chemistry education in primary and secondary schools to discuss how it is addressed in the research literature. A systematic review was conducted, including 102 articles published between 2000 and 2020. Through inductive analyses, the articles were categorised into four groups: (1)…

Various similar primary studies report varying impacts of applying blended problem-based learning (Blended PBL) in improving students' 21st-century skills. This study aims to group similar studies on the effect of blended PBL on students' 21st-century skills in science learning through meta-analysis. In addition, studies were analyzed on…

Describes the implementation of problem-based learning (PBL) pedagogy in an undergraduate classroom. Briefly describes PBL philosophy and protocols, and gives guidance in choosing and integrating a PBL problem into the curriculum. Contains 13 references. (WRM)

This discussion of teaching science as a design activity emphasizes open-ended problem solving. Highlights include the relationship between teachers and students; hypotheses as solutions; and descriptions of four microworlds, or computer simulations, in chemistry, geography, physiology, and genetics which use graphic interfaces.
