Direct linkNovick, Laura R.; Catley, Kefyn M. – Science Education, 2014
Science is an important domain for investigating students' responses to information that contradicts their prior knowledge. In previous studies of this topic, this information was communicated verbally. The present research used diagrams, specifically trees (cladograms) depicting evolutionary relationships among taxa. Effects of college…

This study investigates the effect of a conceptual change approach over traditional instruction on students' understanding of DNA, gene and chromosome concepts. 52 10th grade students belonging two different classes participated the study. One of the classes was assigned randomly to the control group, and the other class was assigned randomly to…

Akaygun, Sevil – Chemistry Education Research and Practice, 2016
Visualizing the chemical structure and dynamics of particles has been challenging for many students; therefore, various visualizations and tools have been used in chemistry education. For science educators, it has been important to understand how students visualize and represent particular phenomena--i.e., their mental models-- to design more…

Strunk, Catherine M.; King, Keith A.; Vidourek, Rebecca A.; Sorter, Michael T. – Health Education & Behavior, 2014
Youth suicide is a serious public health issue in the United States. It is currently the third leading cause of death for youth aged 10 to 19. School-based prevention programs may be an effective method of educating youth and enhancing their help-seeking. Most school-based suicide prevention programs have not been rigorously evaluated for their…

Cetingul, Ipek; Geban, Omer – Hacettepe University Journal of Education, 2011
This study was conducted to explore the effectiveness of conceptual change oriented instruction over traditional instruction on students' understanding of acids and bases concept. Besides, effects of gender difference and science process skills on students' understanding of acids and bases were also investigated. Analysis of the results showed…

Cetin, Pinar Seda; Kaya, Ebru; Geban, Omer – Journal of Science Education and Technology, 2009
The aim of this study is to investigate the effectiveness of conceptual change oriented instruction (CCOI) over traditionally designed chemistry instruction (TDCI) on overcoming 10th grade students' misconceptions on gases concepts. In addition, the effect of gender difference on students' understanding of gases concepts was investigated. The…

Zydney, Janet Mannheimer – Computers & Education, 2010
This study investigated the effectiveness of multiple scaffolding tools in helping students understand a complex problem. In order to support students with this task, a multimedia learning environment was developed based on the cognitive flexibility theory (CFT) and scaffolding through computer-based tools. Seventy-nine 10th-grade students in an…

Van Dooren, Wim; De Bock, Dirk; Depaepe, Fien; Janssens, Dirk; Verschaffel, Lieven – Educational Studies in Mathematics, 2003
Previous research has shown that--due to the extensive attention spent to proportional reasoning in mathematics education--many students have a strong tendency to apply linear or proportional models anywhere, even in situations where they are not applicable. This phenomenon is sometimes referred to as the "illusion of linearity". For example, in…

Peer reviewedMorrison, Todd G.; And Others – Youth & Society, 1997
Examines gender stereotyping, homonegativity, and erroneous beliefs about sexual coercion among adolescents. Responses from 1,045 questionnaires from tenth- and twelfth-grade students show males are more homonegative, gender stereotypic, and supportive of erroneous beliefs about sexual coercion than are female adolescents. Additionally, findings…
