Eryilmaz Mustu, Özlem; Özkan, Emin Berk – Asia-Pacific Forum on Science Learning and Teaching, 2019
The aim of this study is to determine the pre-service teachers' perceptions of atom and atomic structure through a word association test. It is important to concretize the concepts having a significant influence on the learning of subjects. Through this concretization, students' understanding of the concepts and accordingly of the subjects is…

Moutinho, Sara; Moura, Rui; Vasconcelos, Clara – EURASIA Journal of Mathematics, Science & Technology Education, 2017
Model-Based learning is a methodology that facilitates students' construction of scientific knowledge, which, sometimes, includes restructuring their mental models. Taking into consideration students' learning process, its aim is to promote a deeper understanding of phenomena's dynamics through the manipulation of models. Our aim was to ascertain…

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…

Ceylan, Özge; Yigit, Elif Atabek – Science Education International, 2018
In this study, the use of concept cartoons in a particle structure of matter unit was investigated using the flow map of 7th-grade students' academic achievement. The development of their cognitive structures and thoughts about concept cartoons was analyzed. 27 experimental and 27 control group students who were studying in the 7th grade…

Supasorn, Saksri – Chemistry Education Research and Practice, 2015
This study aimed to develop the small-scale experiments involving electrochemistry and the galvanic cell model kit featuring the sub-microscopic level. The small-scale experiments in conjunction with the model kit were implemented based on the 5E inquiry learning approach to enhance students' conceptual understanding of electrochemistry. The…

Batzli, Janet M.; Smith, Amber R.; Williams, Paul H.; McGee, Seth A.; Dosa, Katalin; Pfammatter, Jesse – CBE - Life Sciences Education, 2014
Genetics instruction in introductory biology is often confined to Mendelian genetics and avoids the complexities of variation in quantitative traits. Given the driving question "What determines variation in phenotype (Pv)? (Pv=Genotypic variation Gv + environmental variation Ev)," we developed a 4-wk unit for an inquiry-based laboratory…
