Floating and sinking (FS) is a key topic in science education, both at primary and secondary levels. The interpretation of FS phenomena, however, is challenging due to the difficulty of the scientific concepts and explanatory models involved (e.g., density, buoyancy), along with students' everyday experiences, which conflict with scientific…

In light of extensive research demonstrating widespread misconceptions about electricity, this paper describes a learning study that targeted the most likely source of difficulty--failure of middle school pupils to develop a mental model that serves as a bridge between static and current electricity. During the intervention, pupils first envision…

Early childhood science and engineering education offer a prime context to foster approaches-to-learning (ATL) and executive functioning (EF) by eliciting children's natural curiosity about the world, providing a unique opportunity to engage children in hands-on learning experiences that promote critical thinking, problem solving, collaboration,…

The ability to design and interpret controlled experiments is an important scientific process skill and a common objective of science standards. Numerous intervention studies have investigated how the control-of-variables-strategy (CVS) can be introduced to students. However, a meta-analysis of 72 intervention studies found that the opportunity to…

Experiments in different forms can certainly be suitable tools for increasing student interest in physics. However, educators continuously discuss which forms of experimenting (if any) are the most beneficial for these purposes. At the Faculty of Mathematics and Physics, Charles University, Prague, two different forms of physics experiments are…

This quasi-experimental study explores how student cumulative situational interest, short-term preference generated by particular conditions such as novel experiences can be developed into better individual interest, an enduring predisposition to engage in certain activity such as chemistry lessons. A continuous intervention of integrating novelty…

The aim of this study was to evaluate the effects of living animals on pupils' intrinsic motivation and knowledge. Various studies from the late 1970s and 1980s stress the high effectiveness of authentic learning experiences in pupils' knowledge acquisition. However, there are only few current empirical studies on this topic. The research question…
