The Impact of Girls' Interscholastic Sport Participation on Academic Orientation

Abstract

This study was designed to assess the influence of athletics and other extracurricular activities on the academic orientation of female high school students. Senior girls were categorized into groups—labeled athlete-only (comprising students who participated only in athletics as an extracurricular activity), service-only (students who participated in service activities only), athlete-service (students participating in both) and neither (students whose extracurricular activities included neither athletics nor service activities). Categorizations were based on listings from their high school yearbooks. Those taking the ACT college entrance exam (N = 487) were compared on composite and English scores to the other groups, and to national and state averages. Analyses of covariance, controlling for SES and extent of activity involvement revealed that the athlete-only group recorded the lowest average scores, but these could not be attributed to the participation category to which they belonged. Rather, socioeconomic level and extent of activity involvement were factors contributing to most of the differences between groups in which higher SES levels and higher levels of involvement were predictive of higher ACT scores. Moreover, none of the groups' scores were significantly different from national or slate averages. These results refute the notion that involvement only in athletics is detrimental to educational achievements for females, and lead to certain recommendations for longitudinal, multi-measure investigations of academic orientations.     

Sport Commitment Among Competitive Female Gymnasts

The purpose of this study was to examine age and competitive level differences in the relationship between determinants and level of sport commitment. Gymnasts (N = 304) comprised three age groups (8–11, 11–14.5, and 14.5–18 years) and two competitive levels (Levels 5–6 and 8–10). Multiple regression analyses revealed: (a) perceived costs and social constraints from parents and best friends were the strongest predictors of commitment for the youngest gymnasts, (b) perceived costs, personal investments, and parent social constraints predicted commitment for 11–14.5-year-old gymnasts, and (c) perceived competence and costs predicted commitment for the oldest gymnasts. Competitive level differences also emerged; for Level 5–6 gymnasts, personal investments, perceived costs, coach social support, and social constraints by coach, best friend, and teammates were predictors of commitment. Personal investments and teammate social constraints were significant predictors for Level 8–10 gymnasts. Developmental factors and additional determinants are important to consider in further studies of the sport commitment model.     

Effects of Weight Reduction on Selected Anthropometric,Physical, and Performance Measures of Wrestlers

Abstract

Eighteen girth, skinfold, cardiovascular, cable tension strength, and response time measurements were obtained in order to assess the effects of weight reduction on a group of college wrestlers. In 10 of the 18 measurements mean differences were found to be significant at the .05 level from the statistical analysis provided by a repeated measures analysis of variance. It was generally concluded that for the ten subjects studied up to 7 percent of body weight may be lost without adversely affecting factors apparently related to wrestling performance —strength, cardiovascular endurance, and response time.     

"Show and tell" in the gymnasium revisited: developmental differences in modeling and verbal rehearsal effects on motor skill learning and performance.

Little research has investigated the observational learning process from a developmental perspective. The purpose of this study was to extend previous research by considering two factors: performance versus learning and sequencing versus form scores. Children (N = 60) comprising two age groups (5-0 to 6-11 and 8-0 to 9-11 years) were randomly assigned to verbal rehearsal only, model only, or model plus verbal rehearsal conditions. The task was a 6-part motor skill sequence in which proper sequencing and quality of form were assessed. A 2 x 3 x 4 (age group by model type by trial blocks) repeated measures MANOVA revealed a significant three-way interaction. Older children performed equally well under any of the model type conditions during both performance and learning. For younger children, a model plus rehearsal was superior to rehearsal only on sequence and form at performance and learning and superior to model only on sequence scores during the first two performance trial blocks. Model only and model plus rehearsal conditions were equally effective on form scores. These results suggest that age differences exist in the modeling of motor skills under conditions varying in model type, sequence and form scores, and performance and learning phases.     

Microanalysis of variable-interval performance during stimulus compounding

Additive summation is observed when more responses are emitted to the simultaneous presentation (tone-plus-light) of independently conditioned stimuli (tone and light) than to either stimulus presented alone. The current experiment sought to determine if this increased rate during tone-plus-light was a function of a new modal interresponse time (IRT) or a differential mixing of pauses with a modal IRT characteristic of the responding in tone and light alone. Three rats were trained on a three-component multiple schedule where tone and light were each associated with a variable-interval 30-sec schedule while a variable-interval 100-sec operated in the simultaneous absence of these stimuli, tone-off and light-out. Baseline response rates were 2–4 times as high in tone or light as in their absence. In testing, more responses were emitted to tone-plus-light than to tone or light by all animals, but the modal IRT was in the 0.2–0.4-sec IRT bin for all test conditions. Tone-plus-light controlled fewer long IRT values and more responses in the short modal category than tone or light alone. These results support the response mixing hypothesis of stimulus control; i.e., no “new” behavior was observed during the novel combination of stimulus elements, only a mixture of previously reinforced behavior patterns in different proportions.     

Activity-based learning of statistics: Using practical applications to improve students' learning

Many obstacles are involved in teaching statistics to undergraduates, including high attrition rates, students' anxiety, and a limited ability to grasp difficult concepts. These concerns can be addressed effectively by implementing strategies that require students to be actively engaged in the learning of statistics. First, we discuss how activity-based strategies and information technology can be an effective way to teach a statistics course. Second, we discuss how we changed a statistics course to include activity-based strategies. Finally, we discuss how cooperative learning, as a type of activity-based strategy, can increase students' understanding of statistics.
