Describes the indexing concept of entry terms, and evaluates existing terms in the Medical Subject Headings by comparing them to the results of an automatic indexer. The results of experimental testing of a strategy for creating entry terms using the algorithms of the automatic indexer are presented. (31 references) (CLB)

We are studying two groups of preservice teachers' conceptions, progression and especially the concept of function in connection to y=x+5 when they are taking a course in algebra or one in calculus in their third and sixth term, respectively, in a teacher preparation program. There is a similar development in that they use to a higher degree a…

The REPRESENTATION Project, 1998-2000, carried out research within elementary schools in six European countries: Denmark, France, Greece, the Netherlands, Spain, and England. Altogether, 31 schools participated, ranging from large inner city schools in Paris and Amsterdam, to a 20-student school in a Greek village. In each school, one class of…

This document features the experiences of three science teachers who video and audiotaped classroom proceedings in order to go back over what was said in classroom events, to explore the intentions and ideas that were perhaps not fully understood at the time. Mary DiSchino, who teaches 3rd and 4th graders, teaches a science curriculum which she…

From an instructional perspective, it is conceivable that employing an appropriate hypertext architecture should have the advantage of facilitating learning by representing logically the interrelationships between different units of information contained within the hypertext. Furthermore, there would, however, appear to be a sound theoretical…

The purpose of this study was to explore the use of concept map assessments in freshman level general chemistry courses. Two strategies were employed in this study. The first strategy involved the creation of a web based concept mapping program capable of scoring concept maps drawn by students. The second strategy involved comparing different…

Investigated use of concept and Vee-mapping strategies with regular seventh- and eighth-grade science students (N=155), focusing on changes in student acquisition of science knowledge and problem-solving performance. Includes methods of teaching Vee mapping, evaluating the maps, anectdotal records of Piagetian clinical interviews, findings, and…

The material presented in this article is intended to help students learn how to learn. The seven key concepts of David Ausubel's assimilation theory for cognitive learning are discussed with reference to the classroom. Concept mapping is suggested as a tool for demonstrating how the seven key concepts function. (SA)

Describes a study that examined changes in the structural complexity of knowledge held by two groups of introductory college-level biology students (N=68, N=93). The subjects constructed concept maps at four-week intervals throughout the instructional term. Contains 49 references. (DDR)

Students in general and science-oriented curriculum courses used concept mapping as the basis for developing lesson plans after having first learned the technique through a "fast-track" approach developed by the author. Resulting lesson plans were high in quality with few, if any, sequencing errors. (LZ)

Experiences of giftedness were studied through written responses to a phenomenological inquiry with seventh (n=40), eighth (n=41), and ninth (n=4) graders. Responses were qualitatively reduced to representative items, and students then performed card sorts of items. Analysis of students' sorts suggest positive and negative elements of the…

Studies of the relationship between students' propositional knowledge (as measured by concept mapping tasks) and their study strategies (as measured by self-report questionnaires) for electricity in first-year university courses are described. The effect of propositional knowledge and prior knowledge on both conceptual knowledge and study…

This article describes the genesis and development of concept mapping as a tool for science education. It also offers an overview of this special issue of the "Journal of Research in Science Teaching" and comments on the current state of knowledge representation. Suggestions for further research are made. (49 references) (Author/PR)

Describes how three biology textbooks present content related to photosynthesis through construct of elaboration. Concept maps were created for each textbook. Results are discussed in terms of quantity of elaboration, relevance of ideas used to elaborate major concepts, relationship of nature of elaboration to intended readers, and general…

Discussed is the use of concept mapping as a tool to enhance meaningful learning for college autotutorial biology students. Student attitudes toward concept mapping is described. The correlation between SAT scores and concept mapping was investigated. (KR)
