Ahmet Tasdere; Mehmet Fatih Kaya – Science Education International, 2023
The aim of the study was to investigate the effect of the Common Knowledge Construction Model (CKCM) on 10th-grade students' conceptual understanding of the buoyancy and density of liquids topic. Within a pre-experimental (one group pre-test/post-test) research design, this study was conducted with 22 of 10th-grade students. To collect data, the…

Yildirir, Hasene Esra – International Journal of Research in Education and Science, 2020
The purpose of this study was to determine the state of secondary school students? cognitive structures about argument and related concepts and to reveal the change in their cognitive structures regarding these concepts after the implementation of the argumentation-oriented approach in science lessons. This study was conducted in Grade 6, 7, 8…

Srivastava, Anveshna – Biochemistry and Molecular Biology Education, 2016
When students build physical models from prefabricated components to learn about model systems, there is an implicit trade-off between the physical degrees of freedom in building the model and the intensity of instructor supervision needed. Models that are too flexible, permitting multiple possible constructions require greater supervision to…

Akaygun, Sevil; Jones, Loretta L. – Chemistry Education Research and Practice, 2013
Helping learners to visualize the structures and dynamics of particles through the use of technology is challenging. Animations and simulations can be difficult for learners to interpret and can even lead to new misconceptions. A systematic approach to development based on the findings of cognitive science was used to design, develop, and evaluate…

From Fragmented Knowledge to a Knowledge Structure: Linking the Domains of Mechanics and Electromagnetism.
Peer reviewed Peer reviewed
Bagno, Esther; Eylon, Bat-Sheva; Ganiel, Uri – American Journal of Physics, 2000
Describes the MAOF physics education program which is designed to relate large parts of mechanics and electromagnetism to each other via the key concepts of field and potential, while at the same time treat students' conceptual difficulties. Finds that students who studied with the MAOF program significantly improved their physics knowledge…

Bischoff, Paul J. – Science Education, 2006
This study explored preservice teachers' (n = 25) knowledge structures and their mastery of content knowledge in relation to their ability to diagnose the strengths and weaknesses of a fourth grader's videotaped explanations of a scientific phenomenon, i.e., molecular kinetic properties of air. Participants' knowledge structures were analyzed…
