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…

Discussed is the issue of the appropriateness of applied science approaches to evaluation in environmental education. The relationships between characteristics of applied science approaches to evaluation and the special characteristics of environmental education are explored. (Author/YP)

Examines science textbook language and determines some characteristics of them: distant authorial voice, concern for precision, limited context, limited syntax, and rhetorical model. Suggests three further researcher needs. (YP)

Reported is a study which investigated reasons responsible for the lack of enthusiasm among junior high teachers in implementing a new biology curriculum in Israel. Identified variables related to high expectations set at the ideal level, the greater role given to verbalization, and mechanical or routine implementation approaches. (ML)

This study examined the impact of a biology course emphasizing computer simulation on student achievement and student attitudes toward science. The students in the experimental group were placed in a class limited to 16 students to have 2 students to each computer. (YP)

This study was undertaken to determine whether a biology preparatory course given at an urban community college was helping students to develop the proper skills and background necessary to successfully complete follow-up courses in biology. Data indicated a mathematics score was the main discriminator between pass/fail groups of the preparatory…

Investigates whether enriching text with analogies, similes, and metaphors has an impact on student cognitive learning and attitudes. Reports no gain on achievement, negative gain on attitude, no gain on proposition recall test, and negative gain on student attention to the text. (YP)

Reports on a study designed to focus on staff development delivery variables in the context of science teacher workshops. Data suggest that 8 to 16 hours is a minimum amount of time for staff development if teachers are to implement new strategies into their science classrooms. (TW)

Describes and examines the effects of the eight-week Summer Science Training Program at the University of Iowa. There was no significant differences between students who had completed high school physics and those who had not on the final course examination, course grade, and attitudes toward physics. (Author/YP)

Explains science teachers' perceptions and decisions about the development and implementation of a science/technology/society curriculum. Discusses the teacher interviews based on teachers' decisions. Summarizes five themes: concerns over content, discomfort with grouping, uncertainties about evaluation, frustrations about student population, and…

Identifies two stages in research on scientific literacy; a composite saturation stage in which definitions covered all objects of science education, and a stage when researchers focused on small manageable portions of scientific literacy. Describes formal, nonformal, and informal science teaching. (TW)

Examined are the global issues of population growth, world hunger, air quality and atmosphere, and water resources in 10 middle school science textbooks. Less than two percent of text pages were devoted to these issues and no significant differences were found between textbook series. (Author/YP)

Investigates the manner and the degree to which science teachers consider the nature of the subject matter in their decision making when they plan and deliver instructional tasks. Considerations for student development, curriculum guide objectives, and pressures of accountability dominated decision making. (Author/YP)

Calls for differentiating between three kinds of studies of students' conceptions in science, namely descriptive studies, explanatory studies, and studies attempting to foster conceptual change. Cites the literature about student perceptions and science instruction. (TW)

Examines 11 elementary science texts in terms of conceptual structure and reasoning demands using concept maps. Reports that (1) the conceptual structures vary widely across texts; (2) most of the structures are well defined; and (3) the reasoning demands are above the developmental capabilities of most of primary-level children.
