Abstract The purpose of the study was to assess the fundamental characteristics of the ice skating start through an analysis of the acceleration patterns exhibited during the first 20 feet of skating. A Locam 16 mm camera, operated at 100 frames per second, was used to film the skating starts of four subjects. The subjects possessed varying levels of skating ability ranging from moderately skilled to expert. The segmental method was used to determine the centers of gravity of each subject at every fourth frame of film throughout the first 20 feet of the starting task. The horizontal coordinates were plotted to form displacement curves. A fifth degree polynomial curve fit was used to smooth the displacement and velocity curves in order to generate acceleration-time functions. Analysis of the results indicated that similar patterns existed for all subjects. The acceleration curves typically revealed high acceleration initially and this lasted for approximately 1.25 seconds. The curves then tapered off and a...

Abstract The purpose of this study was to describe the effects of teacher expectations on specific teacher-student behaviors occurring during physical education instruction. The study further described the effects of teacher expectations on the development of the student's self-concept. Five elementary school teachers were asked to rate their students according to how they expected each to perform in terms of physical achievement. A total of 100 students, the highest 10 and the lowest 10, in each of the five classes, comprised the sample. All five teachers used in the study were experienced physical education teachers who had previous instructional experience with the children under observation. A dyadic version of Cheffers Adaptation of Flanders Interaction Analysis System was the observational tool used to identify the teacher-student behaviors. The Martinek-Zaichkowsky Self-Concept Scale for Children was used to determine whether there were self-concept differences between the two groups. The results o...

Abstract This investigation attempted to ascertain the types of recreation activities in which the mentally retarded participated and the frequency of such participation. The frequency of recreation participation of 36 lower socioeconomic status (SES), mentally retarded, elementary age boys and girls was compared to the frequency of 36 nonretarded lower SES and 36 nonretarded middle SES elementary age boys and girls. All children were from a school district in central Pennsylvania. Mothers (or female guardians) of these children were interviewed using a questionnaire devised for this study. A two by two by four within subjects factorial design denoting with whom and where recreation activity clusters took place was used. Of the 16 dependent measures for the three groups, 11 proved to be nonsignificant and 5 significant among groups at the .05 level. One of these differences was attributed to mental retardation, two to SES, and two to mental retardation and SES. It was concluded essentially that the mental...
