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. (Author/GA)

Examines the effect of relevant group instruction on various children's developmental stages regarding the conception of space. (Author/GA)

Designs a testing situation to examine the presence of combinatorial analysis, to establish construct validity in the use of an instrument, Combinatorial Analysis Behavior Observation Scheme (CABOS), and to investigate the presence of the schema in young adolescents. (Author/GA)

Investigates the extent of understanding of the logic of hypothesis testing by high school students, and whether this understanding is related to scholastic achievement or ability as measured by standardized tests. (Author/GA)

Compares the linguistic performance of the students in three grades exhibiting different levels of performance on five selected Piaget-type tasks, and identifies those tasks which differentiated significantly between the cognitive levels and the linguistic performance of the subjects. (Author/GA)

Describes the design of an instrument to measure the attitudes of teachers toward metrication, and reports on its reliability and validity. (GA)

Comments on a recent article by DeLuca on electronic "measurement of logical thinking" questioning four aspects of the article. DeLuca responds to the criticism on those four aspects in question. (GA)

Explains that Rogers' proposed sequence of development in proportional reasoning is not really a modification of Inhelder and Piaget's task, but could be considered as a new task. Rogers acknowledged the explanation as a valid one. (GA)
