A study of British Columbia high schools found that block scheduling can endanger mathematics achievement. Reduced math scores were attributed to irregular planning time, little opportunity to modify curriculum; and the provincial examination system. Longer time blocks cannot succeed without adequate planning time, curricular restructuring, and…

Determined differences between lecture-demonstration and small-group laboratory approaches on students' (N=74) chemistry achievement and attitudes toward science. Findings indicate that students taught by the laboratory approach achieved better on immediate/delayed posttests than students taught by lecture-demonstration method. More desirable…

Although research has confirmed block scheduling's nonacademic benefits, effects on academic achievement are mixed. Teachers do not always replace lecturing with more effective participatory teaching methods. To work best under an intensive or alternating block schedule, schools should adapt the math curriculum to reduce course redundancy and…

High school social studies students (n=160) were each assigned to 1 of 8 groups defined by possible combinations of 2 teacher uncertainty conditions (uncertainty vs. no uncertainty), 2 teacher "bluffing" conditions (bluffing vs. no bluffing), and 2 lecture notes conditions (students receive lecture notes handout vs. students do not…

Effects of cooperative group learning on students' motivation and achievement were studied for 62 high school students assigned to cooperative learning or traditional lecture groups. Greater gains were made in achievement, efficacy, valuing of algebra, and learning goal orientation for the cooperative-learning group. (SLD)

Naturally occurring aptitude-treatment interactions (ATI) were investigated with three teaching approaches: lecture-recitation, inquiry, and public issues discussion. When the measure of student performance was based on objectives of the approach, the results showed an ATI for ability X anxiety that was partially replicated across studies.…

Compared attitudes toward computer use and achievement in biology for three groups of Nigerian students (n=64): (1) working alone with computer; (2) working in groups of three on the computer; (3) and a control group that received normal instruction (lecture). Students in the second group had the highest scores on attitude. No significant…
