Proteins are essential for cell function, and their biological performance depends on three-dimensional (3D) structures. Insulin is made up of 51 amino acids and is a critical hormone involved in glycaemia regulation. In basic education, concepts involving proteins (synthesis, structure, interactions, and function) are abstract and difficult for…

Urhan, Selin; Dost, Senol – International Journal of Science and Mathematics Education, 2018
Model-eliciting activities are problem-solving activities that differ from traditional problems as they include non-routine, open-ended, and complicated real-life situations with various solutions (Lesh & Doerr, 2003). According to Lesh, Hoover, Hole, Kelly and Post (2000), a model-eliciting activity must follow certain principles, namely, the…

Faircloth, Beverly S.; Miller, Samuel D. – Theory Into Practice, 2011
Harnessing insights from Brophy's (1999, 2008, 2010) notion of scaffolding students' appreciation of learning, this article tackles challenges to student engagement, especially among reluctant students, by exploring two classroom settings in which students' valuing of school content and activities supported their engagement and achievement. The…

On the Roots of Difficulties in Learning about Cell Division: Process-Based Analysis of Students' Conceptual Development in Teaching Experiments
Peer reviewed Peer reviewed
Direct linkDirect link
Riemeier, Tanja; Gropengiesser, Harald – International Journal of Science Education, 2008
Empirical investigations on students' conceptions of cell biology indicate major misunderstandings of scientific concepts even after thorough teaching. Therefore, the main aim of our research project was to investigate students' difficulties in learning this topic and to study the impact of learning activities on students' conceptions. Using the…
