Muammer Çalik; Neslhan Ültay; Hasan Bag; Alipasa Ayas – Chemistry Education Research and Practice, 2024
The purpose of this study is to "meta"-analytically evaluate research that used chemical bonding-based interventions to improve academic performance. Through "meta"-analysis, the present study used several keyword patterns (e.g., chemical bonding, experimental, chemistry education, science education) via relevant databases…

Martin Schwichow; Anastasios Zoupidis – Journal of Research in Science Teaching, 2024
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…

Bar, Varda; Shirtz, Aviv Spector; Brosh, Yafa; Sneider, Cary – Science Educator, 2019
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…

Snetinová, Marie; Kácovský, Petr; Machalická, Jana – Center for Educational Policy Studies Journal, 2018
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…

Ozmen, Haluk; Demircioglu, Gokhan; Burhan, Yasemin; Naseriazar, Akbar; Demircioglu, Hulya – Asia-Pacific Forum on Science Learning and Teaching, 2012
The aim of this study is to examine the effectiveness of an intervention based on a series of laboratory activities enhanced with concept cartoons. The purpose of the intervention was to enhance students' understanding of acid-base chemistry for eight grade students' from two classes in a Turkish primary school. A pretest-posttest non-equivalent…

Toth, Eva Erdosne; Klahr, David; Chen, Zhe – Cognition and Instruction, 2000
Developed and tested a cognitive theory-based intervention teaching a procedure for designing simple controlled experiments to fourth graders. Found that the intervention produced significant gains in students' ability to create controlled experiments, provide valid justifications for their experiments, and evaluate experiments designed by others.…
