The importance of reporting explained variance in ANOVA designs is discussed. Three methods that can be used to obtain estimates of explained variance in ANOVA designs are described and applied to sixteen studies that were reported in recent NARST volumes. Recommends that researchers in science education report explained variance. (Author/DS)

Provides evidence to support the conclusion that relationships exist among Piagetian levels of intellectual development, intelligence quotient, content achievement, and inquiry skills in ninth and tenth grade biology students (N=92). (DS)

Purposes of this study were to (1) develop an instrument requiring several classification activities; (2) investigate the correlation between classification ability and intelligence scores of junior high school students (N=365); and (3) determine if classification ability differs with age and gender. Findings included a significant correlation…

Determined (1) if ninth-grade students (N=221) receiving pictoral treatment with critical attributes highlighted performed better on an identification test than those receiving diagram form instruction, and (2) if high verbal learners receiving a largely diagrammatic treatment performed better on a classification test than high verbal students…

Determined (1) how student attitudes toward science change as a consequence of changes in learning environment across time and (2) extent to which student attitudes are associated with student characteristics and their learning environment. Indicates students enjoy science at elementary and secondary levels with no sharp dropoff in student…

Determined whether a test of cognitive style can predict student (N=87) performance on a test of scientific knowledge, and examined possible interactions between cognitive style and teaching method in terms of student achievement. No significant relationships between cognitive style and student performance or between cognitive style and teaching…

Determined if certain variations in the format of Inhelder and Piaget's Equilibrium in the Balance task have any effect on how students (175 undergraduate and 32 ninth graders) are classified. Suggests that researchers allow subjects to experiment with the apparatus to insure proper classification of stage of development. (Author/DS)

Reexamined Piagetian stages of males (N=182) and females (N=176), ages nine to eighteen, using cluster analysis, and sought information concerning occurrence of stages and influence of different tasks and gender on cluster patterns. Findings, among others, indicate that deviation from Piagetian stages was influenced by gender and type of task.…

Study investigated the relationship between children's (N=66) length conservation status and ability to acquire specific length measurement skills, and examined the interaction between mode of instruction (manipulative, graphic, and abstract) and conservation status. The expectation that length conservers would outperform nonconservers on…

Investigated science teachers' (N=149) perceptions of the curriculum objectives they were expected to implement on a daily basis and whether they regarded cognitive objectives as more important than attitude objectives. Results indicate that science teachers do regard cognitive objectives as more important than affective objectives. (Author/DS)

This study examined whether a relationship existed between field-dependence-independence and scientific attitudes of sixth-grade students in SCIS. Findings indicated that such a relationship was not statistically significant. (Author/DS)

Indicates that the ability of tenth-grade students (N=600) to distinguish between teleological or anthropomorphic explanations and causal ones is different and independent from the ability to distinguish between teleological or anthropomorphic formulations and factual ones, and that special treatment should be given to develop each of these two…

Explored the relationship between high school students' (N=37) performances on the Tomlinson-Keasey and Campbell paper-and-pencil test of formal operations and a set of traditional, individually administered, Piagetian developmental tasks. Correlations between the traditional, formal operations tasks and paper-and-pencil tests were low. (Author/DS)

This position paper briefly highlights the more pervasive research and applications problems in science education and suggests a possible way to organize ideas so that psychological paradigms will have educational value. (CS)

Examines whether instructing Nigerian primary children in science in their mother tongue (Yoruba) is any more efficacious than instructing them in science in the English language. Also assesses and compares the levels of cognitive development of two groups of Yoruba-speaking children, one instructed in Yoruba and another in English. (CS)
