Teaching Gene Technology in an Outreach Lab: Students' Assigned Cognitive Load Clusters and the Clusters' Relationships to Learner Characteristics, Laboratory Variables, and Cognitive Achievement
Peer reviewed Peer reviewed
Direct linkDirect link
Scharfenberg, Franz-Josef; Bogner, Franz X. – Research in Science Education, 2013
This study classified students into different cognitive load (CL) groups by means of cluster analysis based on their experienced CL in a gene technology outreach lab which has instructionally been designed with regard to CL theory. The relationships of the identified student CL clusters to learner characteristics, laboratory variables, and…

Scharfenberg, Franz-Josef; Bogner, Franz X. – Research in Science Education, 2013
Our research objective focused on examining the instructional efficiency of tutoring as a form of instructional change as opposed to a non-tutoring approach in an outreach laboratory. We designed our laboratory based on cognitive load (CL) theory. Altogether, 269 twelfth-graders participated in our day-long module "Genetic Fingerprinting." In a…

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…

Randler, Christoph; Hummel, Eberhard; Glaser-Zikuda, Michaela; Vollmer, Christian; Bogner, Franz X.; Mayring, Philipp – International Journal of Environmental and Science Education, 2011
Research has shown that emotions play a significant role in the learning process and academic achievement. However, the fact that measurement of emotions during or after instruction usually requires written responses on lengthy research instruments has been given as a reason why researchers have tended to avoid research on this topic in…

Scharfenberg, Franz-Josef; Bogner, Franz X.; Klautke, Siegfried – International Journal of Science Education, 2008
Our research objectives focused on monitoring (i) students' activities during experimental teaching phases in an out-of-school gene technology laboratory, and (ii) potential relationships with variables such as work group size and cognitive achievement. Altogether, we videotaped 20 work groups of A-level 12th graders (n = 67) by continuous…
