The Impact of Group Processing on Achievement in Cooperative Learning Groups.

Abstract The impact on achievement of (a) cooperative learning, in which members discussed how well their group was functioning and how they could improve its effectiveness, (b) cooperative learning without any group processing, and (c) individualistic learning were compared on daily achievement, postinstructional achievement, and retention. Third-grade American students (N = 84) were randomly assigned to the three conditions, stratifying for sex and ability level. The results indicate that the high-, medium-, and low-achieving students in the cooperation with group processing condition achieved higher on all three measures than did the students in the other two conditions. Students in the cooperation without group processing condition achieved higher on all three measures than did the students in the individualistic condition.

The effect of cooperative and individualistic learning experiences on positive and negative cross-handicap relationships

Abstract The effects of cooperative and individualistic learning contingencies on interpersonal attraction, social acceptability, and self-esteem between handicapped and nonhandicapped fourth-grade students were tracked and compared. Sixty-nine students were assigned to conditions on a stratified random basis controlling for handicap, sex, and age. They participated in the study for 45 min a day for 54 instructional days during science class. Nonhandicapped peer ratings of the social acceptability of each handicapped student and several attitude measures were obtained four separate times at 18-day intervals. The results indicate that continued use of cooperative learning contingencies promote positive growth in interpersonal attraction, social acceptability, and self-esteem between handicapped and nonhandicapped students. The results also indicate that when cooperative learning contingencies are replaced with individualized learning contingencies, decay in the above-mentioned variables occurs.

Success of a Professional-Development Model in Assisting Teachers to Change Their Teaching to Match the More Emphasis Conditions Urged in the National Science Education Standards

Lead teachers were a major part of a staff-development program first offered in 1983 for science teachers in Iowa. Later, the National Science Teachers Association (NSTA) reform project called Scope, Sequence, and Coordination (SS&C) involved 20 school districts and worked annually with new teachers involved during the 7-year funding period, 1990–1997. Eight lead teachers, who provided assistance to staff teams, were studied in 1998 and 2000 to determine how their teaching practices changed during the 3 years following funding. The results indicated that the eight teachers have continued to grow in terms of constructivist strategies beyond the funding period and in ways illustrating that the kind of teaching advocated by the National Science Education Standards (National Research Council, 1996).

Comparing science learning among 4th-, 5th-, and 6th-Grade Students: STS versus textbook-based instruction

Fifteen 4th-, 5th-, and 6th-grade teachers from five school districts each taught two sections of science —one with a Science-Technology-Society (STS) approach and the other with a more traditional textbook approach in which basic science concepts were the major organizers. Local, current, and personally relevant issues provided the context and organizational scheme for the STS section. The two approaches were evaluated using six different domains: (1) Concept, (2) Process, (3) Application, (4) Creativity, (5) Attitude, and (6) Worldview. The results indicate no difference in results at any grade level in the Concept domain. However, significant differences in terms of learning with large effect sizes were found in the other five domains. STS provided an impressive teaching approach utilizing the features of the National Science Teachers Association’s (NSTA) (2006) position paper regarding STS in all assessment domains.
