Black students, other minorities and white students can show significant increases in achievement in biology by using a cooperative learning model. Concentrating on cooperating with group members toward a common goal is the ingredient that makes this cooperative learning model work. This study was designed to investigate the effects of cooperative…

Much research has been conducted regarding the effectiveness and efficiency of cooperative learning on groups of students. Many student may think they like cooperative learning. Such students, however, may really prefer traditional learning in that same subject if they were taught by the same instructor. Students that have not been taught by the…

This document contains the abstracts of most of the papers, symposia, and poster sessions presented at the 63rd Annual Conference of the National Association for Research in Science Teaching (NARST). Subject areas addressed include teacher preparation; informal settings; cognitive models; classroom practices; teaching methods; student learning;…

A study comparing cooperative and competitive learning approaches in science was conducted with 630 eighth-grade Nigerian students using five different treatments. Combinations of cooperation and competition were found to be the best methods of instruction. Procedural demands on teachers using these methods were relatively easy. (DH)

The reward structure of a classroom refers to the means by which a teacher motivates students to perform school tasks. This document reports on a study in which academic achievement in competitive and reward-structured environments was examined in two high school sophomore level biology classes of equal academic ability. Each class was pretested…

Analyzed outcomes of using worksheets or simulation games in a high school biology course. Results (based on data obtained from 83 students) showed that students taught by the simulation game method had comparable achievement gains to students taught using worksheets. Differences related to sex are noted and discussed. (JN)

Determined whether significant differences exist in cognitive achievement and in the level of acquisition of practical skills among ninth-grade students (N=1025) in cooperative, competitive, and individualistic learning conditions in science laboratories. Results are discussed in terms of their implications for more productive science laboratory…

This study ascertained whether or not computer assisted instruction (CAI) enhanced the quality of the educational experience and resulted in increased learning. The study involved the teaching of a 3-week instructional unit on population genetics and evolutionary processes to advanced placement biology students. The control group (N=38) received…

Investigated the influence that changing the form of the learning cycle's exploration/expansion phases had on the content understandings developed by students and their attitudes toward the learning procedures used. The naturalistic data presented show that students believed learning physics is enhanced by the regular-form learning cycle (which…

Different learning cycle sequences were investigated to determine factors accounting for success of the cycle, compared learning with conventional instruction, and examined relationships between Piaget's theory and learning cycles. Results show that the normal learning cycle sequence is the optimum sequence for achievement of content knowledge in…

Investigated was the influence on learner outcomes of the repeatable testing provision of Bloom's mastery learning model for ninth graders in an Introduction to Chemistry and Physics course. Neither student achievement nor attitude toward learning science was favorably influenced by repeatable testing. (MNS)

The use of computers to facilitate learning is yet to make an appreciable in-road into the teaching-learning process in most developing Third World countries. The purchase cost and maintenance expenses of the equipment are the major inhibiting factors related to adoption of this high technology in these countries. This study investigated: (1) the…

Several studies of the validity of the intensive time-series design have revealed a post-intervention increase in the level of achievement data (the "momentum effect"). Reports on the development and use of a technique to study the effect as it is observed in several data sets on the learning of plate tectonics. (Author/JN)

The first (exploratory) phase of the Learning in Science Project focused on science teaching/learning in the Form 1 to 4 level (ages 10 to 14) and sought to identify problems and difficulties in several areas. Provided in this paper are comments obtained during structured/unstructured interviews (from students, ex-students, teachers, headmasters,…

Students in a classroom with living plants and animals scored higher on knowledge of biology and attitude toward science and sciencing measures than students in a control group. These findings suggest that living displays serve to stimulate interest and curiosity which in turn influence attitude and achievement. (Author/JN)
