Described is the generative learning strategy, an approach which encourages pupils to discuss their out-of-school ideas about plant breathing, drinking, wood production, soil, minerals, and leaves, and assist them in linking appropriate ideas together to form an explanation of the origin of plant materials. (CW)

Describes the use of brain models to connect the microscopic level accessible by molecular and cellular techniques with the systems level accessible by the study of behavior. Discusses classes of brain models, and specific examples of such models. Evaluates the strengths and weaknesses of using brain modelling to understand human brain function.…

Examines the place of mental models in the process of knowledge construction, particularly by the relationship between mental models and computer models in that process. Analyzes and discusses children's use of spreadsheets to build their own computer models. Suggests that the process of building models on a computer may provide direct support to…

Suggests study by Kuhn and others (PS 524 345) is too ambitious and that the processes described are not wholly representative of developmental stages. Argues the methodology of study was progressive problem solving, and that experimenter's questions resulted in contrived stages. (JW)

Compares the effects on the knowledge structure of the learners of using two different Mindtools--semantic networks and rule-based expert systems--for representing the content of a course. Results showed that students in the semantic network class possessed more hierarchical knowledge structures than the other group. (Contains 29 references.) (JLB)

Sixty elementary students with learning disabilities were interviewed about parallel domains of uncontested and contested knowledge on the topic of space, including questions of morality and questions of empirical law. Students clearly distinguished between uncontested and contested knowledge, suggesting that they are capable of working with…

Investigated the continuous fraction concepts of (n=59) students in grades four, five, and six. Students were confident and accurate when performing sharing tasks, but were much less successful on continuous quantity tasks involving formal fraction language and symbol manipulation fraction tasks. (14 references) (Author/MKR)

Contrasts interpretive and cognitive approaches to explaining teachers' thoughts and actions, exploring epistemological and ontological assumptions that underlie research on teaching. Cognition is discussed as individual mental processing versus a social event in which thinking is shared, intersubjective, and practical. The influence of the place…

Considered stereotype change within a framework of dual process models. Using three experiments, manipulated task involvement, source credibility, and message quality. Findings proved dual process as appropriate when considering the processing of stereotype-disconfirming information and processing's impact on existing stereotypes. Different…

Examines retrieval theory in terms of free-text searching, citation analysis, and knowledge synthesis, and supports the claim that topical relevance relationships are not primarily matching relationships. Suggests that the assumption of topic matching between user needs and texts topically relevant to those needs is often erroneous. (51…

Presented is an alternative method for analyzing the van Hiele level of students' geometrical reasoning. The accuracy of students' answers may afford a description of acquisition and/or expertise for each of the van Hiele levels simultaneously rather than the traditional assignment and evaluation of one level at a time. (JJK)

Two groups of adolescents and a group of Coast Guard officials were interviewed about hypothetical political problems. Solutions presented were arrayed along a continuum of expertise, according to the complexity of subjects' political schemata and skills used in problem representation. (BC)

Discusses children's ideas about colored objects and colored shadows, with special attention to the organization of these ideas into mental models. The clarification of these models provides instructional tools that serve to assess and confront students' naive conceptions. Subjects were visitors to a science museum who engaged in interactive…

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)

Discussion of courseware development focuses on a transaction shell approach that stresses flexibility and reusability of the courseware. Topics discussed include high-level programing languages, authoring languages, authoring systems, knowledge structures, and knowledge acquisition; and an example for applying the transaction shell approach to…
