Explores the conceptual change of two classes of grade 10 students (n=48) in their genetics learning in an Australian girls' school that uses laptop computers. The study used an interpretive, case-based design with multiple data collection methods and a multidimensional conceptual change framework. Over seven weeks, the students learned genetics…

This document features a lesson plan in which genetic traits are identified and classified using a genetic wheel by playing several different games that introduce genetic diversity and highlight why it is important within populations. Samples of instruction and assessment are included. (KHR)

The purpose of this study is to examine one possible source of misconceptions that are held by students of genetics--the teachers. Is there evidence to suggest that prospective biology teachers might have misconceptions about genetics and related concepts? If prospective biology teachers have misconceptions in genetics, how do these misconceptions…

Past research in a high school genetics classroom has shown that groups of students solving computer-generated genetics problems differed in their application of assessment criteria to the tentative models they generated, and that consistent application of certain model-assessment criteria correlated with success in proposing adequate explanatory…

This is the third in a series of five horse project activity guides for youth. Levels 1-3 focus on "horse-less" activities, while Levels 4 and 5 zero in on riding and horsemanship. Each guide has an achievement program to encourage youth to learn and develop life skills. The assistance of a horse project helper in completing the achievement…

Discusses the importance of forages in agriculture, and expresses the need for the same high level of technology that is used in the production of corn, wheat, and rice to be applied to forage production. Describes promising forage species, breeding objectives, and breeding procedures used in research. (JR)

The condition of life experienced by people of lower social-class position tend to impair their ability to deal resourcefully with the problematic and the stressful. Such impairment would result only for people who are both genetically vulnerable and exposed to considerable stress--these may affect the lowest social classes with special severity.…

Examines several issues relative to the role of immaturity in the instruction of man, and how the young are inducted into the species. (DM)

Describes ways that computer-assisted instruction (CAI) is used in a high school biology course, including: (1) mastery of specific objectives; (2) CAI as a self-check; (3) computer games; (4) laboratory simulations; (5) genetics instruction; (6) writing programs; and (7) remedial assistance and testing.
