A remedial instructional strategy (developed and implemented in ninth-grade physics classes) was found to significantly affect low/mixed ability students' achievement. The method was developed on the basis of a needs assessment of students' backgrounds and a detailed task analysis of the physics course's cognitive demands. (JN)

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)

Previous studies have documented the effectiveness of feedback in improving students' achievement, but few studies have examined the effectiveness of summaries or reviews. This study examines the respective and combined effects of feedback and review on students' achievement, retention, and level of cognitive development. A total of 55 ninth-grade…

This study compared the effects of an advance organizer and a prerequisite knowledge passage on learning and retention measured at low and high levels of the cognitive domain. The advance organizer group performed better on the framework test; the prerequisite knowledge group performed better on prerequisite knowledge test. (Author/YP)

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…

This case study presents a narrative summary of the evaluation of a two semester computer assisted instruction (CAI) project in an all minority high school. Use of PLATO software with Control Data microcomputers brought about modest achievement advantages, higher internal locus of control, more positive attitudes toward school and specific course…

In a previous study, the benefits of matching instruction with students' needs were examined. Three personality variables were used for the purpose of matching: Maslowian need level; locus of control; and cognitive style. This study used the ninth-grade physical science students (N=301) participating in the previous study to (1) examine…

In 1986, a total of 11 different populations involving more than 1000 schools and more than 20,000 students participated in the Second IEA Science Study (SISS). This digest discusses findings related to curricular patterns and student outcomes. Ratings were done at grades 5, 9, and 12, to ensure that the achievement tests reflected the science…

Some ninth-grade students from three Knoxville City high schools have continuously performed substantially less well than those from other city schools in the Tennessee State proficiency tests. A task force developed a plan to work with grade 8 in the middle schools and grade 9 in the high schools to prepare students to perform better on state…

Data on science achievement, student attitudes and educational practices in the United States and 23 other countries were collected. This data was taken from random samples of the fifth, ninth, and twelfth grade levels. This report card conveys a few of the findings of the Second IEA Science Study regarding the performance of students in the U.S.…
