Tested the hypothesis that spatial reasoning is a significant correlate both of formal thought, as defined by Piaget's measures of the proportionality schema, and of achievement in science. Sex differences in proportional reasoning and spatial skills in 6th-form (11- year-old) students from a New Zealand high school were also examined. (CS)

Investigated the appropriateness of audiotutorial instruction for a wide spectrum of students. Questions whether there are significant relationships between personal traits of variables of achievement and success, whether there is a different set of personal traits for high and low achievers, and how well a battery makes ex post facto predictions.…

Investigated the learning by eighth-grade students of the concept of crustal evolution, asking questions that deal with how time-efficient procedures can be devised that measure concept learning effectively and whether these procedures yield valid information on the learning of a science concept. (CS)

Explored the effectiveness of the self-initiated modular approach for learning a unit in a human gross anatomy course, and student preference of cadaver dissection versus cadaver prosection. A color scale, the Chromatic Differential Test (CDT), was used to assess general student attitude and preference. (CS)

Investigated the effects of variation in teacher wait-time on science achievement for students (N=733) in 11 Australian middle schools. Conclusions provide evidence that the extension of teacher wait-time produces desirable changes in achievement. (CS)

Investigates whether placement of pictorial adjuncts before or after related textual material enhances instructional effectiveness for learners of varying ability. Junior high students (N=84) were randomly assigned to one or three treatments in which a diagram of the hydrologic cycle was inserted before, after, or omitted from the text. (CS)

Questions Whether first-grade student participation in selected experimental activities from the BSCS-ESSP enhances skills in listening as measured by the Cooperative Primary Series Listening Test (CPSLT). (CS)

Explored was the relationship between performance and gender for junior- and senior-high students (N=108) on six Piagetian-type tasks developed to measure infralogical spatial groupings. Results indicated a significant relationship between performance and gender on four tasks, in which males outscored females. Implications for science teaching are…

Examined and confirmed were the positive effects on achievement of a multisensory, hands-on review experience at the Kansas Health Museum on the comprehension and application of knowledge and concepts about the human body by sixth-grade students as compared to a classroom review of the same information. (CS)

Three research questions are explored relating the psychological phenomenon of premature closure to (1) age, (2) Piagetian developmental level, and (3) ability to generate hypothetico-deductive strategies. Children (N=141) in grades 1-6 were interviewed and administered light-and-button tasks to describe these relationships. (CS)

Described is a study which relates Piaget's theory of cognitive development to Lowenfeld's types of perceptual aptitude (i.e., visual v haptic orientation). General interpretations of questionnaire results from university students (N=312) are made that postulate a relationship linking incidence of perceptual and logical ability. (CS)

Inquiry and scientific inquiry are distinguished in which various connotations associated with the term "inquiry method" are reviewed. Basic competencies to be acquired by students before scientific inquiry can be accomplished are listed; reasons for these prerequisites are given. (CS)

Analyzed are university instructor behaviors in introductory and advanced level laboratories of botany, chemistry, geology, physics and zoology. Science Laboratory Interaction Categories--Teacher (SLIC) was used to assess 15 individual categories of teacher behaviors in the areas of questioning, giving directions, transmitting information,…

In this study, worksheets were adapted from an Elementary Science Study unit, "Batteries and Bulbs," to develop an individualized set of instructional materials on electricity. Research questions were asked regarding relationships of teaching technique (individualized v conventional) to achievement and attitudes, gender, and interactions of…

Represented are results from a national survey study of public school teaching in 1970-71. A hypothesized path model is given relating use of Science Course Improvement Projects (SCIP) and offering of environmental education programs to several independent variables deemed to be relevant in using SCIP in secondary schools.
