This paper reports on a study of ecology teaching and learning in a Swedish primary school class (age 10-11 yrs). A teaching sequence was designed to help students read nature in a river ecosystem. The teaching sequence had a "bottom up" approach, taking as its starting point a common key organism--the freshwater shrimp. From this…

Discriminatory ability of several pediatric outcome tools was assessed relative to Gross Motor Function Classification System (GMFCS) level in patients with cerebral palsy. Five hundred and sixty-two patients (400 with diplegia, 162 with hemiplegia; 339 males, 223 females; age range 4-18y, mean 11y 1mo [SD 3y 7mo]), classified as GMFCS Levels I to…

Unrest in the early 1970s stimulated a need to understand undergraduates' motivations. The Clark-Trow Typology (Clark & Trow, 1966) examined student behavior (i.e., academic, collegiate, vocational, and non-conformist) according to identification with the institution and involvement with ideas. The Student Interest Survey included questions…

There is currently much interest in ascribing outcomes to Masters (M) level programmes. It is particularly difficult to define M level outcomes in bioinformatics for students on non-specialist programmes. An approach is described that attempts to discriminate undergraduate from M level in a data-mining exercise. Differentiation of level is based…

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…

The second edition of "Professional Issues in Therapeutic Recreation: On Competence and Outcomes" is greatly expanded to include a wider variety of introductory materials and updates on current professional issues. The second edition represents a timely review of the state of affairs in the profession of therapeutic recreation. This book contains…

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…
