Studies effects of verbal participation during enquiry on achievement among three differently treated groups of four eighth-grade classes each with I.Q. test, reading test, sociometric, and academiometric results taken into account. Indicated the preference of strategies involving more students, particularly more girls, in class discussion. (CC)

Study was conducted to compare effects of pass/fail and conventional five point grading systems on student achievement, teaching practices, teaching techniques and student attitudes. The sample consisted of eight sections of chemistry students. Analysis of data indicated lower achievement scores and poorer attitudes of students on pass/fail…

The third-year evaluation results of an investigation extending through grade six. Studied performance of the same population, appearing in two previous evaluations, with sex, socioeconomic status, and maturity taken into account. Indicated third grade Science Curriculum Improvement Study (SCIS) children were superior to non-SCIS controls in both…

Studied effectiveness of teaching conservation of chemical identity, composition, and mass to 12 boys and 11 girls of ages ranging from 11.11 to 12.10, using techniques analogous to Piaget's. Indicated the necessity of course re-examination to facilitate attainment of conservation concepts. (CC)

Two postlaboratory discussion strategies (Probing and Nonprobing) were tested for effectiveness on learning science concepts by sixth graders. Similar laboratory experiences were provided to all, but discussion strategies differed. Analysis indicated significantly higher mean gain scores for the Nonprobing strategy group. (PS)

The purpose of this study was to analyze the effectiveness of long-term, tutorial-type computer assisted instruction (CAI) in high school chemistry. Analysis showed scores of non-CAI students significantly higher than the CAI group. However, CAI students learner material faster. (PS)

This study was conducted to analyze the classification ability of middle class, culturally diverse, and visually impaired children after instruction in a Science Curriculum Improvement Study (SCIS) unit. The SCIS unit was effective in improving student abilities to classify. (PS)

This study was designed to determine if experiences in manipulating physical objects could increase classification abilities of deaf students, ages 10 to 13. Goldstein-Sheerer Object Sorting Test forms were used in a pre- and post-test design. Analysis of data revealed increased scores of deaf children in experimental group. (PS)

Conducted a study similar to Fryback and Daugs' experiments among 15 sixth grade classes, using Cloze procedure to measure gains and a teacher rating to evaluate teachers. Indicated the absence of significant differences in pupil gains through the use of either one- or five-level materials. (CC)

The contributions of Biological Sciences Curriculum Study, Chemical Education Materials Study, and the Physical Science Study Committee courses to the understanding of science among Israeli students are compared. Changes in science process inventory scores in concurrent courses in grades 9-12 are examined. Common misunderstandings about the nature…

Students who had taken a Biological Sciences Curriculum Study biology course in high school were more likely to choose a biology-related science program in college than students who had taken other high school biology courses. (AL)

Grade 8 students using the Introductory Physical Science course improved their scores on a test of science processes (observing, comparing, classifying, quantifying, etc.) after studying the first five chapters of the materials. Some evidence supporting a hierarchy of process skills is reported. (AL)

University students in 1971 were as positive in their attitudes toward science as a 1967 sample. There were no significant differences over time related to age, sex, religious preference, parent's education, father's occupation, academic major, or high school type. Presents data concerning the relationship of attitude toward science and student's…

Students whose Physical Science Study Committee (PSSC) physics course was supplemented with the PSSC films did not achieve significantly higher scores on the PSSC Achievement Test or the Test on Understanding Science than students who did not see the films, when intelligence and science background were used as covariates.
