Cheng, Kell; Leung, Allen – International Journal of Mathematical Education in Science and Technology, 2015
This paper reports findings of an explorative study that examine the effectiveness of a GeoGebra-based dynamic applet in supporting students' construction of the formal definition of the limit of a sequence or convergence. More specifically, it is about how the use of the applet enables students to make connections between the graphical…

Barron, Kenneth E.; Hulleman, Chris S.; Inouye, R. Bryce; Hartka, Thomas A. – National Center on Scaling Up Effective Schools, 2015
In our session, we showcase work from a researcher-practitioner partnership between James Madison University, the University of Virginia, and Harrisonburg City Public Schools that is focused on developing a continuous improvement process to translate social-psychological interventions into teaching practices that enhance motivation and learning.…

Huberty, Carl J; And Others – 1983
Three methods of transforming unordered categorical response variables are described. One is a method using dummy binary variables. The second method analyzes all categorical variables simultaneously and is based on an eigenanalysis of frequency patterns scaled relative to within-groups variance, jointly developed by J. E. Overall and J. A.…

Lewis, Charles – 1982
The nonparametric approach to test theory discussed here has its roots in the early work of Guttman, Lazarsfeld, and Meredith; and more recently in the work of Cliff and in Tatsuoka and Tatsuoka. Mokken's extensive treatment of this subject concentrated on defining, constructing, and testing unidimensional scales, based on responses to dichotomous…

Benson, Jeri; Hocevar, Dennis – 1983
The present paper represents a demonstration of how LISREL V can be used to investigate scale invariance (1) across time (its relationship to test-retest reliability), and (2) across groups. Five criteria were established to test scale invariance across time and four criteria were established to test scale invariance across groups. Using the…

Goldenberg, E. Paul; Kliman, Marlene – 1988
Computer graphing makes it easier for students and teachers to create and manipulate graphs. Scale issues are nearly unavoidable in the computer context. In interviews and protocol analysis with six students from grade 8, and 12 students from grades 11 and 12, it became apparent that some aspects of scale are clearly understood very early while…
