Three variations of computer assisted instruction feedback were used with college astronomy students. On only one measure, a posttest, did subjects' achievement by treatments differ significantly. Significant differences in attitudes according to treatment group were not observed. (CP)

Treatment and control groups were used to test the effectiveness of a written instructional program in basic and integrated process skills. Findings revealed that the treatment group achieved higher than the control group on six of eight process measures following the experiment. In addition, subjects from the treatment group asked fewer closed…

Classifies 12-year-old schoolchildren as either convergers (those who excel on conventional tests but do poorly on open-ended tests), divergers (those who excel on open-ended tests but do poorly on intelligence tests), or all-rounders (those who are equally good or bad on all tests) and searches for correlates with academic achievement, and…

The development and administration of a scientific literacy test designed to measure achievement of the objectives of the Science Curriculum Improvement Study (SCIS) project is described. Students who had completed the six year SCIS curricula were compared with those who had used other science materials. SCIS subjects scored significantly higher…

Investigates the effects of combined learning cues (pretest and behavioral objectives) on the achievement levels of teachers in an inservice course. Subjects receiving the combined learning cues did not achieve at a significantly higher level than did those who did not receive the combined learning cues. (CP)

Seventh-grade students enrolled in two average classes were pretested, randomly assigned to two training groups--an active group in which physical materials were employed and a verbal group in which standard textbook procedures were employed--immediately posttested and posttested one month later. The active group showed greater achievement and…

Describes a procedure using the Delphi method by which members of the National Association for Research in Science Teaching (NARST) generated a list of 15 cognitive competencies for secondary school science teachers. (CP)

Compares frequencies and styles of questioning strategies used in Modern Biology and Biological Science Curriculum Study--BSCS Green, BSCS Yellow and BSCS Blue secondary school biology textbooks. Findings revealed significant differences between textbooks in terms of number and type of questions used. (CP)

Describes steps involved in the construction of a 15-item test to measure formal reasoning in junior and senior high school students. From analysis, the author concludes that the test has face, convergent, and factorial validities. (CP)

Examines conditions for the acquisition of the proportionality concept and attempts to improve the ability of remedial college students in an urban university to solve proportions. Specifically, the study was designed: (1) to observe the acquisition of the proportionality concept through training on the operations of group-structured tasks, and…

With a sample of 229 ninth-grade chemistry students, an investigation of students' retention abilities as related to instructional approach (inductive or deductive), IQ, gender, and anxiety level was conducted. Results showed that subjects experiencing deductive instruction performed slightly better on an immediate retention test. Girls…

Measures whether pre-school children (ages 34 to 65 months) can master concepts of the first five exercises of K-level science--A Process Approach (SAPA) within seven weeks with four lessons of 10 minutes each week. More than 90 percent of the sample of 226 achieved at the 90 percent competency level. (CP)

Uses a Group Embedded Figures Test (GEFT) as an indicator of field-independency in an investigation with college graduate students. Results reveal that GEFT scores were not affected by the treatment of 18 hours of instruction in Science Curriculum Improvement Study (SCIS) materials or by pretesting effects. (CP)

Two instructional approaches and a control group were used in this study. Metric instruction in a college introductory physical science course was divided between: a) Approach A in which volume instruction followed that of length and area; b) Approach B in which volume was stressed but area was not introduced; and Approach C, the control (no…

Reports on the administration of a biology cognitive preference test to 177 science-oriented high school students. Subjects were asked to rank responses or "extension statements" to items according to their preference. It was found that the high-ability students as a group had a very high preference for questioning and low preference for recall.…
