Tested were six levels of a twelve-level hierarchical model for the attainment of concepts leading to the conservation of displacement volume. Presentation was by individual interview using either objects or drawings to present tasks. Results show five of six tested followed anticipated order and that method of presentation showed no significant…

Describes a study which used fourth and sixth grade children who had used Science - A Process Approach" and compared their performance with that of a control group on two conservation-of-volume tasks. Performance of the volume tasks was found to be related to age and score on the Learning Hierarchies Test and not to previous science program…

Forty-five children, ages nine through eleven, were divided into control group and experimental groups that read or wrote hunches concerning a discrepant event involving sliding blocks. Those who generated hunches were shown to learn more in subsequent inquiry behaviors designed to explain the discrepant event. (MLH)

Indicates that the use of verbal rewards which are not congruent with behavior will result in less efficient problem-solving than either a neutral, no-reward situation, or the use of rewards which are congruent with the problem-solving behavior. The giving of congruent rewards improved the problem-solving efficiency of girls but not of boys. (LS)

Questions the conclusions drawn in the article by Billeh and Pella (EJ 023 200), and suggests that there are real differences between the attainment of concepts by Jordanian and American students. (AL)

The quantitative relationship of measured ability to measured science learning was synthesized from reported correlations in 34 studies on grade 6-12 students over a 16 year period. Findings indicate a stable central tendency and deviation of correlations across ability and cognitive outcome categories and across several study variables.…

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 the effect of cue specificity on the transmission of information and learning through the use of graphical materials in science. (GA)

A group of students from grades four through twelve were tested on ten binary operations in four truth conditions. It was found that propositional operations which had greater inclusiveness or breadth of concepts were more difficult to comprehend. (MLH)

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)

Reviews research in science instruction studies with similar independent variables, involving grades 6-12 and reported within the 1963-1978 period. An analysis of 52 studies revealed six clusters that possessed significant positive cognitive outcomes. Includes the finding that systematic innovation provides positive improvements over traditional…

Investigated students' (N=43) conceptions of what happens when water boils, evaporates, and condenses, and when ice melts. Results obtained from clinical interviews indicate that childrens' conceptions are quite different from those of scientists and that their ideas can sometimes be influences in unintended ways during instruction. Implications…

Investigates the effects of teaching 120 first grade children specific strategies for nonvisual seriation on their performance on post-tests and retention tests. Results show that simple seriation can be learned and retained. (HM)

Initial textbook investigations indicate that more new words/phrases are introduced than in a similar time frame in which foreign languages are studied. Reviews these initial studies, studies of vocabulary mastery in foreign languages, and general research concerning vocabulary development. Reports on occurrence of technical/special words in 25…
