The multitude of procedures for testing hypotheses about mean contrasts often presented in statistical methods textbooks is unwarranted. This article demonstrates that nearly all such research can be handled by a single contrast test statistic often attributed to R. A. Fisher. (TJH)

Issues in the detection and interpretation of interaction effects between quantitative variables in multiple regression analysis are discussed. Recent discussions associated with problems of multicollinearity are reviewed in the context of the conditional nature of multiple regression with product terms. (TJH)

Cognitive care training, also known as dementia training, has changed significantly, and negatively, since 1993 in New York State nursing homes. The research reported in this paper examines the employment requirements for cognitive care training and the actual post-employment cognitive care training. The research involved a replication of the…

This paper reports on an investigation comparing the employment salary of bachelor degree in accounting graduates with associate degree in accounting graduates two years after their graduation. Using hierarchical regression analyses, this study shows the predictive strength of participants' academic qualifications, age, gender, GPA, professional…

The purpose of this study was to explore the relationship between high school students' perceptions of the importance of school counselor multicultural competence (SCMCC) and student's characteristics (i.e., students race, SES, sex, grade level, and contact with the school counselor). Participants in this study were students enrolled in two…

As the emphasis on measures of student academic achievement increases, educational researchers and practitioners are interested in identifying factors that demonstrate effectiveness in supporting student achievement. This quantitative, correlational study explored the influence of emotional intelligence on closing the achievement gap. A study of…

This study investigated characteristics and behaviors of middle school principals that enhance the efficacy of new and experienced middle school teachers. Existing research has established a positive relationship between high levels of teacher efficacy and increased student achievement. Prior research has also demonstrated a positive link between…

It is hypothesized that factors related to teacher burnout influence treatment adherence. This study examines the relation of teacher burnout to the frequency and quality of behavioral intervention implementation. A sample of 45 general and special education teachers were trained to implement the Good Behavior Game, an intervention designed to…

This study evaluated the predictive validity of two preemployment screening devices--the Urban Teacher Perceiver Interview and the Academic Skills Assessment portion of the Praxis Series test--as used by an urban high-need and hard-to-staff school district. Specifically, we compared predictor scores with subsequent teacher assessment scores…

This study explores what motivates a student to enter medical school by first measuring students' strength of motivation and then by looking for relationships between motivation and career-related values and approaches to learning.

A total of 473 students in their…

Computer-based interviewing systems could use models of respondent disfluency behaviors to predict a need for clarification of terms in survey questions. This study compares simulated speech interfaces that use two such models--a generic model and a stereotyped model that distinguishes between the speech of younger and older speakers--to several…
