Complexity thinking is relatively new to education research and has rarely been used to examine complex issues in physics and engineering education. Issues in higher education such as student retention have been approached from a multiplicity of perspectives and are recognized as complex. The complex system of student retention modelling in higher…

Shepard-Kruskal's nonmetric multidimensional scaling procedure (KYST) is used to discern those statistical concepts which are most confusing and/or ambiguous to graduate students, as well as to determine if a series of lectures in statistics will influence students' responses to more closely approximate those of their professors'. An instrument…

Describes the use of ALSCAL, a computer program for multidimensional scaling, to map enrollment in 49 electives at Drexel University's College of Information Studies during two time periods. The results for this department are presented, and the explanatory power of this evaluation technique for any curriculum is discussed. (6 references) (CLB)

Alternatives to multidimensional scaling analysis of numerical relationship judgments in extracting information about students' knowledge were investigated. Undergraduate students completed a multiple choice test over knowledge of individual concepts, an essay test covering relationships among concepts, and a relationship judgment test that…

Reports results of a comparison of correlational and multidimensional scaling techniques as tools for analyzing the perceptions of three groups of mathematics teachers (at high school, vocational school, and university levels) of the relative importance of curricular objectives. Discusses the relationship of the two analyses and the implications…

The aim of this study is to suggest an alternative to the essay testing method of assessing structural understanding of concepts, which suffers from time constraints and lack of scoring reliability. In this method, students' relationship judgments between concept pairs are examined directly rather than by means of multidimensional scaling analysis…

Presents an overview of some well-known instruments and recently developed scales for assessing student or teacher perceptions of actual or preferred classroom learning environments. Past research and practical applications followed using the instruments are described. (SM)

Various methods used to assess the content of a test are reviewed, and a new procedure designed to improve on these methods is presented. The two tests considered are a professional licensure examination, the auditing section of the Uniform Certified Public Accountant Examination, and an educational achievement test, a nationally standardized…
