Readers confronted with unfamiliar and controversial scientific debates tend to rely on simple heuristics such as the perceived plausibility to focus their cognitive resources on specific information during comprehension. In the present experiment, we tested the assumption that plausibility judgments as an integral part of comprehension are used…

Understanding chemical models can be challenging for many university students studying chemistry. This study analysed students' understanding of molecular structures using the Lewis structure as a model, and examined what hinders their understanding. We conducted pre- and post-tests to analyse students' conceptions and changes in them. The…

The periodic table is recognized as one of the most powerful tools in science. While it is included in virtually all high school and undergraduate general chemistry curricula, it remains a mystery to many chemistry students who find it impossible to decode. Students are often able to predict periodic trends concerning atomic radius, ionization…
