Based on the hypothesis that teachers possessing extensive and coherent knowledge structures are the most effective teachers, this paper explores the use of a modified ordered tree (OT) technique for measuring teachers' knowledge structures. Two questions are posed: (1) Can a modified OT technique be used to measure teachers' knowledge structures?…

Describes a computer-based methodology for representing mental models as maps, extracting these maps from written and spoken texts, and analyzing and comparing concepts and structures of information within maps. Illustrates the model using data on students and teacher in an undergraduate writing class. Contains about 80 references. (Author/SV)

This paper argues that schema theory and discourse analysis demonstrate that flow charts, grids, and tree diagrams are the most effective models of how the mind organizes ideas in information sets. It shows how each of these frameworks can be used as the central device in an integrated model of language learning. (15 references) (MDM)

Structure of mathematical concept of multiplication and its integration into conceptual system, with respect to formal and informal aspects of understanding for 10 university students, are investigated through linear scale assessment of examples for prototypical effects and through follow-up interview which included direct explanations of…

This research investigates the development of analogy, in particular, the study of the development of systematicity in analogy. Systematicity refers to the mapping of systems of mutually constraining relations, such as causal chains or chains of implication. A preference for systematic mappings is a central aspect of analogical processing in…

Investigates whether distinctions in cognitive structures between formal and concrete operational students effect their ability to produce an accurate cognitive structure, retain geometric content, and retain cognitive structures. Concludes that clear structures can be derived for the students. (Author/YP)

Examines childrens' (age 8-14) conceptions of shadow formation through interviews. Identifies "the trigger model" of shadows and finds that there are multiple roles that children attribute to light. (YP)

Explored group leader cognitions and the function experience plays in leaders' cognitive schemas. Participants (n=60) wrote down their thoughts while viewing a 20-minute videotape of a group session. Examination of the 1,299 thoughts revealed a cognitive-behavior schemata that involved all the elements necessary for effective cognitive skill…

In this article, the author gives a general introduction of a few ideas on cognitive development in children. In the first part, he deals with the topic of development, a process which concerns the totality of the structures of knowledge. He reviews the stages of development of operational structures, distinguishes four main stages of development,…

Provides information on (1) a general indication of change in the cognitive structure of students associated with chemical comprehension; (2) the comparison of clusters of concepts; and (3) a graphical representation of the links among concepts. Argues that constrained word associations serve as a useful tool for mapping aspects of cognitive…

Presents two teaching ideas for mathematics instruction. The first employs "mind maps" as a method to help students learn, record, and recall mathematical information. Provides examples for solving quadratic equations and complex numbers. The second discusses two ways to find the average speed during a trip employing differing constant…

Provides an overview of the nature, purpose, and instructional research related to semantic mapping. Offers a vivid description of how semantic mapping was used in a secondary social studies classroom, including how the teacher and students viewed the method. Suggests ideas and resources for interested teachers. (MJP)

Presents the results of an experiment that evaluated the efficiency of analogy in the conceptual restructuring of a science topic. The experiment involved a fifth-grade class studying water and heat flow. Discovered that analogy can act as an effective trigger for restructuring knowledge. (MJP)

Reviews the current literature concerning prior knowledge in an attempt to clarify problems with the terminology. Identifies the three main problems: lack of definition or vagueness, nominal versus real definitions, and different names/same constructs or same name/different constructs. Includes a conceptual map of prior knowledge terminology. (MJP)

The growth and development of the pedagogical schemata of 16 midwestern preservice teachers in a graduate-level, secondary alternative certification program was studied by examining: (1) pedagogical knowledge comprising the schemata as the program began; (2) pedagogical knowledge comprising the schemata at the end of student teaching; and (3)…
