The purpose of this study was to determine whether the ALT-PE system (Version 2) is valid as a process approach to estimate student achievement. Students (N = 60) were randomly selected from a data base that includes pretest and posttest scores for two volleyball skills and seven sessions of videotaped instruction. Videotapes were collected using two cameras with a split-screen generator so most instruction and practice could be seen. ALT-PE data were coded from the videotapes. In addition to normal ALT-PE coding conventions, coders recorded the skill that was the focus of instruction. Combinations of context and learner involvement categories were summed for each skill across the seven class sessions and to form other logical categories (e.g., total motor appropriate intervals). Achievement scores were calculated by posttest on pretest regression for each skill with the residual score used for subsequent analysis. Residual achievement scores were correlated with summed ALT-PE categories. The results indicate for the serve both total motor appropriate and practice-motor appropriate intervals were related to student achievement. For the pass, practice-motor appropriate intervals were related to achievement and the total motor appropriate-achievement correlation failed significance. These results demonstrate the validity of the ALT-PE system as a process measure of achievement can be partially substantiated. 相似文献

Background: A student’s choice to engage in a learning task is highly related to the student’s environmental stimuli and his or her perception of interest. From this perspective, the construct of situational interest (SI) has been used to interpret students’ motivation in task engagement. SI is assumed to be transitory, environmentally activated, and context specific. It has been conceptualized as a multidimensional construct with five dimensions: instant enjoyment, exploration intention, attention demand, novelty, and challenge. Few prior studies have compared SI between girls and boys in physical education (PE) contexts, and these studies have offered contrasting findings. They were conducted in coeducational (coed) or single-sex contexts and used learning tasks centred on a variety of outcomes: technical or tactical skills, creativity and cultural understanding.Purpose: In the context of the debate on single-sex and coed classes in PE, this study aimed to estimate the effects of single-sex and coed PE classes on students’ situational interest (SI) within learning tasks centred on technical skills. The researchers decided to study learning tasks centred on the development of students’ technical skills, since these tasks are often used by teachers in PE.Participants: The sample consisted of 177 Swiss secondary school students, aged 11–17 years (M?=?14.07, SD?=?1.41, 96 boys, 81 girls).Data collection: The students completed the French 15-item SI Scale after practising a technical learning task in single-sex and coed PE contexts. The researchers chose five physical activities (i.e. athletics, basketball, dance, gymnastics, and volleyball), which are commonly taught in the state of Vaud (Switzerland) and provide a balance between masculine and feminine activities.Data analysis: A two-way repeated-measures MANOVA was performed to examine the main and interaction effects of student sex and class sex composition on the five SI dimensions.Findings: The results showed a main effect of class sex composition on student SI but no main effect of student sex and no interaction effect of student sex and class sex composition. More precisely, the scores for three SI dimensions (i.e. instant enjoyment, exploration intention, and attention demand) were higher in the coed context than in the single-sex context.Conclusions: This study encourages teachers to propose coed PE classes to enhance students’ motivation and engagement when practising learning tasks centred on technical skills. This study offers supplementary evidence of the teacher’s role in promoting student SI. Beyond accounting for students’ dispositional factors (e.g. sex), PE teachers can significantly impact students’ SI in technical learning tasks through instructional choices. 相似文献

Background: Our understanding of the role in which content knowledge (CK) can strengthen instructional models and how that knowledge matters for professional development is limited. It is contended that mere use of an instructional model is insufficient to impact psychomotor learning in meaningful ways.Purpose: This study was conducted to investigate how a teacher's enacted pedagogical content knowledge (PCK) differed as a function of CK and Sport Education (SE), and to investigate the relative contribution of CK and Sport Education on student learning in terms of swimming performance.Methods: Four intact classes comprising 88 secondary school students (age: 16–17 years) were randomly assigned to a Traditional, an Sport Education, a Traditional-CK, and a SE-CK group. All classes were taught by the same teacher during a 10-day unit of instruction in the front crawl.Results: Results showed that the teacher's PCK differed as a function of improved CK. For verbal representations, the amount of cues in the Traditional-CK and SE-CK groups increased about sixfold compared to the Traditional and the SE group. For visual representations, more partially incorrect demonstrations were observed than correct demonstrations in the Traditional and the SE group. More mature and developmentally appropriate tasks were observed in the Traditional-CK and the SE-CK group compared to the Traditional and the SE group. Students in the Traditional-CK and SE-CK groups demonstrated a significant reduction of their amount of strokes on 50?m compared to the Traditional group. A significant interaction effect revealed a larger increase in swimming performance in the CK groups compared to the Traditional and the SE group. Finally, students in the SE group swam significantly more laps than their counterparts in the other groups.Discussion and conclusion: These results show the impact on student learning when CK was added to both Traditional and Sport Education conditions and contribute to the literature for pre- and in-service teachers. The Sport Education model did not contribute to students’ swimming performance. Students in the Traditional and the SE group did not get the same quality of instruction as students in the Traditional-CK and SE-CK conditions. The latter groups received content that was presented differently both as a presentation and in terms of the actual task. In short, students in the Traditional and Sport Education conditions experienced the content differently than those in the Traditional-CK and SE-CK conditions. These instructional differences resulted in students in the Traditional-CK and SE-CK conditions improving their swimming performances in terms of technical efficiency and in terms of 50?m times. 相似文献

The ability to recognize patterns of play is fundamental to performance in team sports. While typically assumed to be domain-specific, pattern recognition skills may transfer from one sport to another if similarities exist in the perceptual features and their relations and/or the strategies used to encode and retrieve relevant information. A transfer paradigm was employed to compare skilled and less skilled soccer, field hockey and volleyball players' pattern recognition skills. Participants viewed structured and unstructured action sequences from each sport, half of which were randomly represented with clips not previously seen. The task was to identify previously viewed action sequences quickly and accurately. Transfer of pattern recognition skill was dependent on the participant's skill, sport practised, nature of the task and degree of structure. The skilled soccer and hockey players were quicker than the skilled volleyball players at recognizing structured soccer and hockey action sequences. Performance differences were not observed on the structured volleyball trials between the skilled soccer, field hockey and volleyball players. The skilled field hockey and soccer players were able to transfer perceptual information or strategies between their respective sports. The less skilled participants' results were less clear. Implications for domain-specific expertise, transfer and diversity across domains are discussed. 相似文献
