Investigated was the effect of concept mapping on science achievement. It was concluded that mapping concepts prior to, during, and subsequent to instruction led to greater achievement. (CW)

Examined were the relationships between three qualities: students' knowledge of chemical terms, the relationships they recognize between these terms, and their achievement. Used were an explanation test, an achievement test, and a connectivity test. Results indicated knowledge of terms was a necessary, but not sufficient, prerequisite for…

This paper presents a theoretical framework for investigating the role of algorithms in mathematical thinking using a combined ontological-psychological outlook. The intent is to demonstrate that the processes of learning and of problem solving incorporate an elaborate interplay between operational and structural conceptualizations of the same…

A study compared university chemistry students' (n=19) performances in creativity exercises, concept mapping, and traditional examinations. Performance in all three correlated with deep study strategy, but low correlations between the three methods suggests that they test different aspects of chemistry knowledge. Use and integration of all three…

Traditional assessment methods are not always suitable for diagnosing learners' knowledge structures at different levels of their expertise. This paper describes an alternative schema-based rapid assessment technique and its application in the area of arithmetic word problem solving. The technique is based on an assessment of the extent to which…

This paper examines the novel problem solving actions of a pair of college students. The analysis highlights the role of the solvers' inferential processes including abductions, deductions, and inductions as structuring resources that contribute to both their understanding of the problems they face and the emerging novelty that constitutes their…

A study investigated the known phenomenon of "intermediate effect" in which medical students with an intermediate amount of knowledge and experience demonstrate higher amounts of recall of the text of a medical case than either experienced clinicians or novices. In this study the amount of activation of prior knowledge was controlled by…

In the late 1960s and early 1970s a considerable amount of research was conducted on methods for authoring and structuring instructional materials by researchers who did not, at that time, have access to the existing delivery systems necessary to fully implement their ideas. One of these methodologies is Structural Communications, developed by…

The Educational Technology Center (ETC) Complex Systems Project was initiated to explore ways of using computers to help students understand systems which have often proven too complex for most high school students to understand. Preliminary work concentrated on the cognitive processes involved in modeling simple systems. This paper describes an…

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…

Examines some of the assumptions associated with attempts to define the "engineering method." Critiques a previously stated definition of this method, and offers an alternative definition that attempts to include the ideas put forth in the previous definition. Discusses the use of engineering heuristics in both definitions. (TW)

Investigated were the relation between functional M-capacity and student performance in solving chemistry problems of increasing M-demand. Student performance decreased as the M-demand of the problems increased. (Author/YP)

Presents findings of a study involving 34 undergraduates, examining how exposure to different belief structures might change an individual's belief structure. Suggests that, when the individual is high in public self-conscious, their belief structures will change after encountering different belief structures. Implies that public posturing can…

Presents two cognitive models that illustrate the commonalities between reading for meaning and solving mathematical problems with meaning. Discusses the importance of number sense in the prior knowledge component of the solving with meaning model and the implications of the models in teaching mathematics. (MDH)

A mapping procedure based on the SOLO Taxonomy developmental model was used to classify the problem-solving strategies of students (n=34) in grades K-2. Only one multiplication problem was used to isolate three components of the problem-solving procedure. (MDH)
