Mierdel, Julia; Bogner, Franz X. – Research in Science Education, 2021
Genetics is known to be one of the most challenging subjects in biology education because of its abstract concepts and processes. Therefore, hands-on experiments in authentic learning environments are supposed to increase comprehensibility and provide otherwise unavailable experiences to students. We applied a hands-on module in an out-of-school…

Krüger, Johanna T.; Höffler, Tim N.; Wahl, Martin; Knickmeier, Katrin; Parchmann, Ilka – Instructional Science: An International Journal of the Learning Sciences, 2022
Interactive computer simulations and hands-on experiments are important teaching methods in modern science education. Especially for the communication of complex current topics with social relevance (socioscientific issues), suitable methods in science education are of great importance. However, previous studies could not sufficiently clarify the…

Wieman, Carl – Physics Teacher, 2015
Undergraduate instructional labs in physics generate intense opinions. Their advocates are passionate as to their importance for teaching physics as an experimental activity and providing "hands-on" learning experiences, while their detractors (often but not entirely students) offer harsh criticisms that they are pointless, confusing and…

Outreach Science Education: Evidence-Based Studies in a Gene Technology Lab
Peer reviewed Peer reviewed

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…

Instructional Efficiency of Changing Cognitive Load in an Out-of-School Laboratory
Peer reviewed Peer reviewed

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…

A Case Study of One Student's Metaconceptual Processes and the Changes in Her Alternative Conceptions of Force and Motion
Peer reviewed Peer reviewed
Direct linkDirect link
Yürük, Nejla – EURASIA Journal of Mathematics, Science & Technology Education, 2007
The aim of this paper was to describe the changes in one student's ideas about force and one-dimensional motion concepts and portray the relevant metaconceptual processes that she engaged in during the implementation of metaconceptual teaching interventions. Metaconceptual processes involves metacognitive processes that are directly acting on or…
