Examined is the extent to which teachers actually hold pseudoscientific beliefs. Described are the study design, sources of pseudoscientific belief, and correlates with various types of pseudoscientific beliefs. Results indicate that many high school biology and life science teachers endorse these beliefs. Implications of this study are discussed.…

Presented is a study in which students' intellectual reasoning development was evaluated following instruction that emphasized formal operations in a traditional lecture format. Results indicated that formal-operational students had significantly more success in the three reasoning areas than transitional students and transitional students had…

Prescriptions for improving student understanding and problem-solving performance related to transmission genetics are discussed. Research on novice/expert problem-solving in transmission genetics is reviewed. (Author/CW)

Explores the learning approaches of males and females and their subsequent biology understanding and achievement. (ZWH)

This book was designed to open up opportunities to expand an instructor's "teaching toolbox." It contains numerous examples of activities or ideas that can be implemented with few modifications to engage students. This book synthesizes one science program's 5-year curricular development experience into a form that addresses and reflects all the…

To examine the dynamism and productive qualities of multicultural interaction, a chromosomal bivalency model was borrowed from the biological sciences. Dilemmas inherent in contact between cultures emerge from the sites of multicultural conflict. Understanding these dilemmas allows interactants to have insights into other cultures as well as into…
