Analyzed and classified were Individualized Science Instruction System (ISIS) minicourse performance objectives and criterion-referenced test items according to Bloom's cognitive "Taxonomy" to determine levels of cognition emphasized. The findings indicate that ISIS minicourse test objectives are written primarily at the knowledge and…

Determined is the logical reasoning necessary to construct line graphs including a straight line with a positive or negative slope and an exponentially increasing curve. The responses of subjects (grades 6-12) were classified into one of nine categories fitting with Piagetian operational structures. (Author/YP)

This was an experiment to test the extended discretion laboratory approach versus a guided-inquiry approach for teaching biology in a university setting. Among three criterion variables (examination, reports, and quizzes), only the laboratory report scores showed differences between groups and group-by-instructor interaction. (Author/YP)

Surveys the trait anxiety profile and preference concerning types of examinations of preservice science teachers. Reports that the students prefer examinations on understanding and analyzing rather than on knowing and remembering, and that students' anxiety states correlate with the type of examination and sex.

Examined are the effects of testing on the achievement of students using self-instructional materials to learn science process skills. Results indicated that frequent quizzes did not differentially affect process skill acquisition. (Author/CW)

Describes a computer program presenting four genetics problems to monitor the problem solving process of college students. Identifies three main areas of difficulty: computational skills; determination of gametes; and application of previous learning to new situations. (Author/YP)

The relationships between mathematical competencies possessed by students and selected student characteristics at the beginning of a semester were examined. The relationship between test scores and the type of mathematics courses taken during the semester students were enrolled in an introductory biology course were also investigated. (Author/CW)

Investigated are the reasons why eleventh-grade Israeli students intend to enroll for a biology, chemistry, or physics course. Topics, activities, motives, attitudes, and grades in the subjects in year 10 are used as predictor variables for correlational analysis. (YP)

Outlines a procedure used to develop a written diagnostic instrument to identify misconceptions and misunderstandings of the chemistry topic. Reports the characteristic data for the instrument, and student understanding of covalent bonding and structure. (Author/YP)

Evaluates the attributes of a microcomputer software package as a supplement to chemistry instruction. Reports higher scores among the students in a control group. Discovers no significant interaction between treatment and development stage. Discusses several implications for further research. Provides the General Chemistry Test and error analysis…

Examined the extent to which students' alternative conceptions changed as a function of age. Reports that many alternative views remain intact throughout the school years. Provides several suggestions for teaching and research within the context of a neoconstructivist view of learning. (Author/YP)
