This paper reports an example of a situation in which university students had to solve geometrical problems presented to them dynamically using the interactive computerized environment of the "MicroWorlds Project Builder". In the process of the problem solving, the students used ten different solution strategies. The unsuccessful…

This article examines the social nature of teachers' conceptions by showing how teachers frame the "mismatch" of students' perceived abilities and the intended school curriculum through conversational category systems. This study compares the conversations of 2 groups of high school mathematics teachers addressing the Mismatch Problem…

This paper details the development of a taxonomy for conceptualizing teaching. This taxonomy is presented as a means to help educators understand and interpret what it is they do and continue in the process of searching and understanding. The purpose of developing a taxonomy, the basis for the dimensions--or subject matter--for the taxonomy, and…

The potential for computer adaptive testing (CAT) has been well documented. In order to improve the efficiency of this process, it may be possible to utilize a neural network, or more specifically, a back propagation neural network. The paper asserts that in order to accomplish this end, it must be shown that grouping examinees by ability as…

M. J. Kolen, B. A. Hanson, and R. L. Brennan (1992) presented a procedure for assessing the conditional standard error of measurement (CSEM) of scale scores using a strong true-score model. They also investigated the ways of using nonlinear transformation from number-correct raw score to scale score to equalize the conditional standard error along…

In this paper, the multilateral comparison method of classifying languages is described and analyzed. It is suggested that while it is espoused as a simple and reasonable approach to language classification, the method has serious flaws. "Multilateral" or "mass" comparison (MC) is not a method of genetic language…

It is difficult to estimate the percentage of examinees who pass National Teacher Evaluation (NTE) tests because many users of the tests require that examinees pass different combinations of tests or use different passing scores for each of the tests. This study first develops a taxonomy of state NTE requirements and then computes passing rates…

This report describes an expanded and revised version of the Economic Research Service's 1979 classification of nonmetro counties, commonly called the ERS typology. The classification has been widely used by researchers, policy analysts, and public officials as a source of information about the economic and social diversity characterizing rural…

This article illustrates how a cluster analysis can be conducted, validated, and interpreted. Data normed for a behavioral assessment instrument with 14 scales on a nationally representative sample of U.S. school children were utilized. The discussion explores the similarity index, cluster method, cluster typology, cluster validity, cluster…

This handbook is designed to provide colleges and universities with initial guidance in establishing an appropriate system of indicators of undergraduate instruction, and to build on this foundation by cataloging a range of exemplary indicators of "good practice" that have proven useful across many collegiate settings. It provides a…

This paper rejects the hardware-based "levels of interaction" made popular in interactive video literature to describe human-machine interaction in favor of a new taxonomy of learner-media interaction based on the type of cognitive engagement experienced by learners. Interaction can be described on three levels, based on the quality of…

The relationship between the notion of "error" in linguistics and language teaching theory and its potential application to error correction in the second language classroom is examined. Definitions of "error" in psycholinguistics, native speech, and English second language instruction are discussed, and the relationship of interlanguage…

This publication discusses the findings of a review of the eligibility classifications and criteria provided by the coordinators of the state and jurisdictional preschool program under the Individuals with Disabilities Education Act (IDEA). Findings revealed seven states use only IDEA, Part B disability categories to identify eligible children of…

This article considers arguments for and against the use of coding systems in classroom-based language research and touches on some relevant considerations from ethnographic and conversational analysis approaches. The four authors each explain and elaborate on their practical decision to code or not to code events or utterances at a specific point…
