The objective of the study is to assess the effectiveness of laboratory activities employing the Predict-Explain-Observe-Discuss-Explain (PEODE) approach in promoting gifted students' interpretation of everyday problems related to fundamental science concepts. This quasi-experimental study involved 54 gifted students enrolled in the Science and…

Berardi, Matthew D.; Gentile, Filippo; Kozik, Isabelle; Gregg, Timothy M. – Journal of Chemical Education, 2021
Aldol chemistry is highlighted in many introductory organic chemistry laboratory experiments because it provides synthesis, mechanism, and experimental challenges for students. In the experiment described here, students synthesize dibenzalacetone derivatives by crossed aldol condensation, observe reaction rates using a semiquantitative rubric, and…

Digital sensors allow people to collect a large quantity of data in chemistry experiments. Using infrared thermography as an example, we show that this kind of data, in conjunction with videos that stream the chemical phenomena under observation from a vantage point, can be used to construct digital twins of experiments to support science…
