Direct linkScharfenberg, 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…

Sesen, Burcin Acar; Tarhan, Leman – Research in Science Education, 2013
This study aimed to investigate the effects of inquiry-based laboratory activities on high school students' understanding of electrochemistry and attitudes towards chemistry and laboratory work. The participants were 62 high school students (average age 17 years) in an urban public high school in Turkey. Students were assigned to experimental (N =…

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…

Potvin, Patrice; Mercier, Julien; Charland, Patrick; Riopel, Martin – Research in Science Education, 2012
This research investigates the effect of classroom explicitation of initial conceptions (CEIC) on conceptual change in the context of learning electricity. Eight hundred and seventy five thirteen year-olds were tested in laboratory conditions to see if CEIC is or is not a productive step toward conceptual change. All students experienced a…

Shegog, Ross; Lazarus, Melanie M.; Murray, Nancy G.; Diamond, Pamela M.; Sessions, Nathalie; Zsigmond, Eva – Research in Science Education, 2012
The transgenic mouse model is useful for studying the causes and potential cures for human genetic diseases. Exposing high school biology students to laboratory experience in developing transgenic animal models is logistically prohibitive. Computer-based simulation, however, offers this potential in addition to advantages of fidelity and reach.…

Burgin, Stephen R.; Sadler, Troy D.; Koroly, Mary Jo – Research in Science Education, 2012
Research apprenticeships for secondary students provide authentic contexts for learning science in which students engage in scientific investigations with practicing scientists in working laboratory groups. Student experiences in these research apprenticeships vary depending on the individual nature of the laboratory in which students have been…
