Effectiveness of Four Track Starting Positions on Acceleration

Abstract

Four sprint starting positions—the bunch, medium, elongated, and hyperextended—were compared on mean elapsed times at distances of 10 and 30 yd. Averages of three starts for each of 30 inexperienced college undergraduate males on each type of start were derived from electronically-controlled measures, the times for both distances being recorded from the same start. Statistical analyses indicated significantly lower elapsed times with the hyperextended starting position.     

Relationships of attitude toward classroom environment with attitude toward and achievement in science among tenth grade biology students

The purpose of the study was to examine the relationship of classroom environment to attitudes toward science and achievement in science among tenth grade biology students. An attitude instrument was administered at three times during the school year to measure student attitudes toward science and the classroom environment. The classroom environment measures examined six areas: emotional climate of the science classroom, science curriculum, physical environment of the science classroom, science teacher, other students in the science classroom, and friends attitudes toward science. Student achievement in science was measured by teacher reported semester grades. The results of the study indicated: (1) student attitudes toward the classroom environment predicted between 56 to 61% of the variance in attitudes toward science, (2) student attitudes toward the classroom environment predicted between 5 to 14% of the variance in achievement in science, (3) student attitudes toward science and attitudes toward the classroom environment predicted between 8 and 18% of the variance in achievement in science.     

Content Validity Studies of Licensing Examinations

Can measurement specialists’current ideas about content validation be implemented with licensure examinations? Does pressure of litigation facilitate or inhibit conducting validity studies?     

Individual differences in memory: Theory,data, and educational implications

This paper examines two theoretical perspectives from which the issue of individual differences in memory can be viewed and relates the perspectives to evidence available in the literature. The paper also reports the results of two studies which bear upon the issue of whether there are individual differences in the retention of learned material. The last section of the paper examines the educational implications of one of the theories presented in the paper.
