This Review of Chemistry Education Research (CER) provides an overview of the
development of research in chemistry education from the early days, when ideas about how …

This article attempts to compile a list of recent tungsten inert gas welding advancements
(TIG). TIG welding only allows for a few millimeters of penetration depth. This limitation of …

This study involves the development of a three-tier diagnostic test to measure high school
students' understanding of states of matter concepts. The States of Matter Diagnostic Test …

We assessed the impact of expert students' instructional quality on the academic
performance of novice students in 12th-grade physics classes organized in an expert model …

This article reports on the development of a Predict–Observe–Explain, POE-based teaching
strategy to facilitate conceptual change and its effectiveness on student understanding of …

What we emphasize and reward on assessments signals to students what matters to us.
Accordingly, a great deal of scholarship in chemistry education has focused on defining the …

The aim of this study was to investigate effectiveness of PDEODE (Predict-Discuss-Explain-
Observe-Discuss-Explain) teaching strategy in helping students make sense of everyday …

We constructed the PDEODE (Predict-Discuss-Explain-Observe-Discuss-Explain) teaching
strategy, a variant of the classical POE (Predict-Observe-Explain) activity, to promote …

The purpose of this study was to investigate the relative effectiveness of experimenting with
physical manipulatives alone, virtual manipulatives alone, and virtual preceding physical …

This paper presents findings from a content analysis of 650 empirical chemistry education
research papers published in two top-tiered chemistry education journals Chemistry …
