Determined whether males, females, minorities, and nonminorities are quantitatively and qualitatively represented in the illustrations of seven contemporary elementary science textbooks (grades 1-6) in a manner that is reflective of society as it was, is, and should be. Results (based on examination of over 5,900 illustrations) are reported and…

Students in a treatment group turned in written summaries of eight lectures, which were returned with chemistry and writing mistakes noted. Although achievement gains were found, results may have been due to the processes involve in organizing/writing the summaries or to the additional time required to complete the assignments. (JN)

This exploratory study determined whether a mathematical model of mastery learning provided a good fit for achievement data obtained from student progress in an introductory, college-level astronomy course for nonmajors. Results provide positive but not compelling evidence that the model of mastery learning is correct. (JN)

Determined if subjects' (N=79) cognitive responses to a persuasive communication are more highly correlated with attitude change than the recall of arguments presented in the communication. Subjects were exposed to a systematically designed persuasive communication and then tested for their retention of arguments presented in the communication and…

Examines research in developmental psychology and science education that has attempted to assess the validity of Piaget's theory of formal thought and its relation to educational practice. Position papers (with little or no empirical support) are not included. (Author/JN)

Students in a classroom with living plants and animals scored higher on knowledge of biology and attitude toward science and sciencing measures than students in a control group. These findings suggest that living displays serve to stimulate interest and curiosity which in turn influence attitude and achievement. (Author/JN)

Investigated implications of cognitive development of preservice teachers (N=91) as it related to their classroom teaching performance. Results obtained support a general portrait of teaching behavior specifically related to teachers of differing cognitive functional levels. Implications for professional training programs are discussed. (Author/JN)

Identified 25 variables (12 of which were scale-specific) related to changes in students' conceptions of science. In addition, a comparison between teacher and student conceptions of science did not support the prevalent assumption that a teacher's conception of science is significantly related to changes in students' conception of science.…

Presents and discusses results of a project that studied the effectiveness of concept and Vee mapping strategies in helping Black inner-city high school students (N=250) learn biology concepts meaningfully. The project sought to assess effects on achievement of the two methods as part of a carefully designed sequence of instruction. (Author/JN)

Sixteen concept words related to "matter" were described as simple textbook definitions and 16 multiple-choice items were constructed for each concept definition. These materials were used to compare the ability of 1,635 Tasmanian and 826 Indian students to recognize the concept definitions and their attendant verbal labels. (JN)

Found that a text mode of programed instruction and tutorial computer-assisted instruction are equally effective modes of instruction for teaching internally- and externally-oriented preservice elementary teachers (N=81) the integrated science process skills. (JN)

Investigated the meaning that Hindi-speaking students (N=826) in India and English-speaking students (N=1,635) in Tasmania preferred when thinking about each of 16 key concept definitions associated with the theme "the nature of matter." Results show marked changes in the development of these preferences which raises issues for science…

Determined which form of kinetic structure (high or low) and/or micrograph content (unified or varied) was most effective on introductory college biology students' (N=100) achievement of reading micrograph skills. Findings, among others, suggest that high kinetic structure instruction does not affect actual reading micrograph skills, but…

Investigated various factors related to a project designed to increase scientific literacy of two age groups by simultaneously exposing middle school children and their parents to short science courses. Findings, among others, show that parents and children made significant gains in learning and that they found the experience enjoyable and…

Data from 60 observations of 10 teachers and 10 each of their students showed that type/quality of teaching strategy predicted 37 percent of variance in engagement and that the more indirect the teaching strategy, the greater the students' involvement in learning tasks. Implications of these and other findings are discussed. (Author/JN)
