Investigates the influence of treatment and the interactions between treatments and selected pupil characteristic variables, with respect to pupil achievement and preference for treatment, and examines treatment-teacher interactions. Among the findings, this study suggests that students prefer to operate in less structured modes for the medium or…

Results of this study indicate that process skills instruction can significantly improve reading comprehension of preservice and in-service teachers. However, the data indicated no significant differences between preservice and in-service teachers' reading comprehension scores after completing process skills instruction. (MA)

Examines the influence of gender, reading level of student, and source of data on science concept formation and retention. Results indicate that reading level of students does influence science concept formation and retention, but gender and source of data (method of instruction) do not. (MA)

Examines the feasibility of using a time-series design intensively in a school situation. Investigates student attitudes toward a biology class using the operant single-subject design. Despite the developmental nature of this study, it demonstrates that the five-item semantic differential is a valid and easily used instrument. (Author/MA)

Findings reveal that students who are skillful in perceptual restructuring attain significantly higher mean achievement scores in science, in knowledge of science, and in the ability to apply what has been learned in unfamiliar contexts than students with low structuring ability. (Author/MA)

Examines the development and usefulness of the Elementary Science Teachers' Preferences (ESTP) test. Findings suggest that this instrument is useful and valid in determining differences between teaching preferences of teacher-centered and student-centered teachers. Findings also indicate that polarized labeling of teachers is inappropriate. (MA)

Studies the effects of student-structured (SSLS) and teacher-structured (TSLS) teaching strategies. SSLS students consistently exhibited lower frequencies of teacher dependency behaviors than TSLS students. Need affiliation results varied with the grade level of students. (MA)

Describes an aptitude treatment interaction (ATI) hypothesis used to investigate relationships among aptitudes and science instructional treatments in terms of student performance. It is proposed that ATI research work in science education will systematically yield reliable generalizations about how to adapt instruction to individuals with…

Presents a 14 point plan for the future of NARST and science education. Suggestions include enlarging the research team, initiating student exchange programs, and determining research priorities. (MA)

Analyzes the performance of the Electronic Task (ET), to test for combinatorial reasoning, over a broad range of subject ages and abilities in order to evaluate it as a substitute for the original Chemical Task (CT). (GA)

Compares two grade 12 science classes, one receiving instruction using the Laboratory-Investigative Approach, and the other using the Lecture-Laboratory Approach, in terms of certain cognitive factors and associated attitudes. (GA)

Reports on a study to determine if teachers who attended a science workshop and then served as "model" teachers by having preservice teachers observe and teach in their classrooms would have more positive attitudes toward teaching science than those who did not. (Author/GA)

Investigates and presents evidence concerning the construct validity of the Test of Higher Cognitive Learning in Chemistry (THCLC), a 40-item multiple-choice test developed to provide assessment of first semester introductory college chemistry students' higher cognitive skills. (Author/GA)

Examines the individual and cumulative effects on achievement of providing students with objectives, sample test items, and a mastery strategy that included diagnostic testing and remedial instruction. Also investigates the effects of mastery learning on achievement of students with different aptitudes for learning. (Author/GA)

Investigates a method to predict best and least suited students for the ISCS instructional approach. Aptitude-treatment interactions associated with ISCS instruction and a set of aptitude, attitude, and skill factors were utilized to make and verify predictions on two dependent variables--achievement and success.
