Heemann, Tim; Hammann, Marcus – Journal of Biological Education, 2020
This paper reports on findings from an analysis of trait-formation tasks in the genetic sections of high school biology textbooks. Drawing on studies exploring a range of problems in students' explanations of trait formation, we investigated trait-formation tasks and analysed their potential for knowledge integration and multi-level mechanistic…

Jördens, Janina; Asshoff, Roman; Kullmann, Harald; Hammann, Marcus – International Journal of Science Education, 2016
Students' explanations of biological phenomena are frequently characterized by disconnects between levels and confusion of levels. The purpose of this research is to investigate the effects of a hands-on lab activity that aims at fostering the ability to reason across levels. A total of 197 students (18 years of age) participated in a randomized,…

Poehnl, Sabine; Bogner, Franz X. – Journal of Educational Research, 2013
Only recently has cognitive load theory been applied in conceptual change approaches. To the authors' knowledge, theirs is the first study to examine the effects on students' cognitive load of an approach contrary to a refutation text design. The authors combined computer and textbook instruction with involving alternative conceptions (ACs) to…

Scharfenberg, Franz-Josef; Bogner, Franz X. – EURASIA Journal of Mathematics, Science & Technology Education, 2014
Nowadays, outreach labs are important informal learning environments in science education. After summarizing research to goals outreach labs focus on, we describe our evidence-based gene technology lab as a model of a research-driven outreach program. Evaluation-based optimizations of hands-on teaching based on cognitive load theory (additional…

Scharfenberg, Franz-Josef; Bogner, Franz X. – International Journal of Science Education, 2010
Our research objective focused on monitoring students' mental effort and cognitive achievement to unveil potential effects of an instructional change in an out-of-school laboratory offering gene technology modules. Altogether, 231 students (12th graders) attended our day-long hands-on module. Within a quasi-experimental design, a treatment group…
