Many students' knowledge of fractions is adversely affected by whole number bias, the tendency to focus on the separate whole number components (numerator and denominator) of a fraction rather than on the fraction's magnitude (ratio of numerator to denominator). Although whole number bias appears early in the fraction learning process and under…

Many students' knowledge of fractions is adversely affected by whole number bias, the tendency to focus on the separate whole number components (numerator and denominator) of a fraction rather than on the fraction's integrated magnitude (ratio of numerator to denominator). Although whole number bias appears early in the fraction learning process…

Class size and student achievement have been debated for decades. The vast amount of research on this topic is either conflicting or inconclusive. There are large and small scale studies that support both sides of this dilemma (Achilles, Nye, Boyd-Zaharias, Fulton, & Cain, 1994; Glass & Smith, 1979; Slavin, 1989). Class size reduction is a…

This study examined cognitive and affective empathy as predictors of proactive and reactive aggression. This study also explored whether levels of cognitive and affective empathy differed among children who use proactive and reactive aggression. Cognitive and affective empathy were measured by the Basic Empathy Scale (Jolliffe & Farrington,…

Background: "NEEDs for Bones" (NFB), based on the Health Belief Model, is a 4-lesson osteoporosis-prevention curriculum for 11- to 14-year-olds. This study examined the relationship between enjoyment of food tastings and interest in NFB. Methods:NFB was administered by teachers as part of standard practice and evaluated after the fourth…

Research conclusions concerning predictors of academic success have been, at best, less than convincing. In fact, these conclusions are more conflicting or mixed when emotional constructs are used. As a result, modern curriculum developers as well as classroom instructors seem to deemphasize, if not ignore, the role of the affective domain in…

This proposed research is part of an on-going line of research of developing questionnaire instruments for use at the elementary school level. Because field trials often use child self-report as outcome measures and sometimes determine implementation fidelity using such measures, evaluation of the validity of the use of such measures with…

An observational study of reading instruction, using the MS-CISSAR protocol, was conducted in general education classrooms, resource classrooms, and self-contained special education/deaf education classrooms in Grades 1 through 4 in public schools within the tri-state area of Ohio, Pennsylvania, and West Virginia. Participants were 24 students who…

A definition of self concept as the individual's perception of how he is perceived by others whom he believes to be significant (important) was used as a basis for defining and assessing self concept in the present study. A number of questions associated with development and the stability of self concept were examined. These include: (1) the…
