Attempting to characterize the research literature on schooling, this paper discusses six possible inquiry perspectives termed analytic, portrait, intentional, structural, societal, and narrative. These perspectives are then analyzed and related to forms of knowledge about educating children. While preferring the narrative approach, the article…

Reports on a study of a small group of girls in Australia that investigated how older adolescents cognitively utilize information on heroin. The study sought to establish the perceived effects of exposures to information and to establish how the perceived effects are associated with changes to the girls' knowledge structures. (Author/LRW)

Explores the relevance of hierarchies to information processing. Suggests that participants in all conditions create hierarchical representations as they work, and those in nonlinear conditions use this structure to guide their exploration of the material. An important function of hierarchies may be to define relationships between concepts.…

Information-processing students solving problems in the 1960s and 1970s accepted the tradition of early experimental psychology in concentrating primarily on the study of "knowledge-lean" tasks in which competence can usually be acquired over short periods of learning and experience. In recent years, experts have examined knowledge-rich…

Presents a project that explored student choice of a solution method for quadratic inequalities. Students were first instructed in the use of the case, critical-number, and graphical methods using the graphing calculator. The majority of students chose graphical methods of solution. (DDR)

Reviews five methods of representing cognitive structures: (1) free word association; (2) controlled word association; (3) tree construction; (4) concept map; and (5) flow map. Discusses the applications as well as the limitations of these methods by comparing the types of analysis that are generated. (Contains 37 references.) (Author/YDS)

Describes trends in students' explanations of biological change in organisms. Student responses to questions on how graphically depicted phenomena occur were analyzed and most students were unable to offer causal explanations. (Contains 27 references.) (DDR)

Examines quantitative models in school physics, looking particularly at the degree to which they match the real world. Explores the positive aspects of a mismatch between models and real world conditions. (DDR)

Explores whether construction of integrated knowledge structures by students can be stimulated by concept mapping and better visualization of concepts and their interrelationships. Significant effects of concept mapping as an instructional method could not be detected. (Contains 18 references.) (DDR)

Shows how box diagrams and AVOW diagrams may be used to solve problems concerning networks of resistors that obey Ohm's Law. Presents outcomes and feedback from students and teachers. Concludes with suggestions as to how these techniques might be incorporated into the teaching of basic circuit theory. (Contains 22 references.) (DDR)

The categories and applications of strategic knowledge as these relate to problem solving in the area of transmission genetics are examined in this research study. The role of computer simulations in helping students acquire the strategic knowledge necessary to solve realistic transmission genetics problems was emphasized. The Genetics…

Explains the philosophy that forms the basis of a high school physical science course based on astronomy and the activity-based textbook that accompanies it. Cites specific examples of misconceptions related to astronomy and recommends various diagnostic and concept change strategies. (DDR)

Explores the rationale behind the importance of teaching young secondary school students how to look for correlation patterns. Describes two lessons that show how pupils can experience zero, positive, and negative correlation patterns between variables. Indicates the possible success of the Cognitive Acceleration through Science Education project.…

Describes a multiple-choice instrument that reliably and validly diagnoses secondary students' understanding of photosynthesis and respiration in plants. Highlights the consistency of students' misconceptions across secondary levels and indicates a high percentage of students have misconceptions regarding plant physiology. (CW)

Describes five astronomy education projects implemented by the Harvard-Smithsonian Center for Astrophysics Science Education Department and funded by the National Science Foundation. Project efforts have concentrated in three major areas: (1) curriculum development; (2) teacher support; and (3) classroom technology. (DDR)
