(7) Ridge Regression for Interactive Models

Richard L. Tate
Florida State University

Abstract: An exploratory study of the value of ridge regression for interactive models is reported. Assuming that the linear terms in a simple interactive model are centered to eliminate nonessential multicollinearity, a variety of common models, representing both ordinal and disordinal interactions, are shown to have “orientations” which are favorable to ridge regression. Comparisons of the potential efficiency of ridge regression to that of ordinary least squares across a wide range of conditions clearly suggest the value of ridge procedures for many centered interactive models.

(6) Evaluating the Use of Word Processors in Teaching Writing Composition

Margaret A. Moore

Susan Turner
Hillsborough School District

Abstract: This exploratory study evaluated the effects of using word processors to aid fourth and fifth grade students in developing writing skills. Results suggest that the compositions of students who used word processors improved more than those of students who did not. An analysis of students’ composition revision characteristics indicates that students who used word processors made more revisions and that their revisions were more meaningful than those of students who did not use word processors.

(5) Criteria for Selling Needs Priorities: The Practitioner’s Perspective

Garrett R. Foster
Florida State University

Margareda Southard
Boston University

Abstract: A survey of instructional, administrative, and policy level personnel who participated in needs assessment studies in twelve Florida school districts revealed several problems in the use of the discrepancy model in needs assessment. These problems relate to the use of size of discrepancy as a basis for establishing needs priorities and to the setting of priorities without adequate consideration of potential solutions. Alternative criteria and procedures for setting needs priorities are presented.

(4) A Computer Needs Analysis Model for School District Testing and Evaluation Offices

Sylvia Kay Fisher
Pinellas County School District

Hirohide Shibutani
Pinellas County School District

Abstract: A generalizeable systems-based needs analysis model was developed to help school district testing and evaluation offices evaluate current problems with their information processing systems and identify additional computer capabilities required to upgrade their system. The model was implemented with the Pinellas County School District Department of Program Evaluation and resulted in a cost-effective prescription for improving their current computer capabilities.

(3) Statistical Rules-of-Thumb

James K. Brewer
Florida State University

Abstract: Six best-selling introductory behavioral statistics and two well-known sampling theory textbooks were reviewed for the presence of rules-of-thumb, The relative frequency and type of rules are reported along with a discussion of their implications for teaching statistics at the introductory level.
