AbstractThe aim of this study was to determine the physical demands of women’s rugby union match play using time–motion analysis and heart rate (HR) response. Thirty-eight premier club level female rugby players, ages 18–34 years were videotaped and HRs monitored for a full match. Performances were coded into 12 different movement categories: 5 speeds of locomotion (standing, walking, jogging, striding, sprinting), 4 forms of intensive non-running exertion (ruck/maul/tackle, pack down, scrum, lift) and 3 discrete activities (kick, jump, open field tackle). The main results revealed that backs spend significantly more time sprinting and walking whereas forwards spend more time in intensive non-running exertion and jogging. Forwards also had a significantly higher total work frequency compared to the backs, but a higher total rest frequency compared to the backs. In terms of HR responses, forwards displayed higher mean HRs throughout the match and more time above 80% of their maximum HR than backs. In summary, women’s rugby union is characterised by intermittent bursts of high-intensity activity, where forwards and backs have similar anaerobic energy demands, but different specific match demands. 相似文献
Many in the field of mathematics education call for elementary schools to have elementary mathematics specialists (EMSs) who provide needed mathematical expertise and support for children and teachers. EMSs serve as a reasonable, immediate alternative to the challenges generated by elementary teachers needing improved mathematical knowledge for teaching in the classroom. However, limited inquiry has explored how to best prepare EMSs and how program features and learning activities influence their development. This mixed-method study identifies some of the interrelated benefits from a K-5 Mathematics Endorsement Program designed to prepare EMSs through examining changes in mathematical beliefs, specialized content knowledge (SCK), and classroom teaching practices during the program. Data (n = 32) were collected over the 2-semester program via belief surveys, a content knowledge assessment, observations of teaching practices, and individual interviews from elementary teachers participating in the program. The findings show some changes in beliefs can be made relatively quickly, other shifts in beliefs take more time and continued support, and changes in SCK and adoption of various aspects of standard-based pedagogy require considerably greater opportunities to learn. The described program features and learning experiences provided a context for these changes and offer considerations for EMS preparation programs. 相似文献
This article examines whether academic libraries are still reclassifying materials, how they are doing so, and if the acquisition of electronic materials has an impact on reclassification efforts. An online survey was sent to the heads of cataloging units at libraries belonging to the Association of Research Libraries to answer these questions. Almost one-third of libraries are currently involved in reclassification projects. Most respondents reported they do not believe that purchasing e-books has affected their decisions about reclassification. The article also examines the faceted search capability of next-generation catalogs and their possible impact on patrons’ use of classification. 相似文献
This study explored the perceptions of preservice teacher candidates who participated in a pilot partnership between a public teacher education preparation program and Junior Achievement (JA). The partnership was grounded in the premise that providing early field experiences to preservice teacher candidates was a necessary requirement of quality teacher education. In an introductory pedagogy course, preservice teacher candidates in their junior year participated in a five-week field experience where they taught JA lessons in partnership schools. The results suggested that preservice teacher candidates perceived an expanded sense of comfort with teaching strategies, classroom management, and diversity during the actual teaching of the lessons in the field experience. Additionally, participants reported increased confidence levels with their own preparation to teach. The partnership with JA that provided a quality, early field experience may have enhanced the general pedagogical proficiencies needed for preservice teachers to succeed as practicing educators. Suggestions for creating a partnership with JA are provided. 相似文献
This study focused on hurtful messages daughters-in-law (DILs, N = 132) reported receiving from mothers-in-law (MILs). Results reveal various hurtful message types: under- and overinvolvement, personal attacks, and hurt communicated to or through a third party. Grounded in attribution theory, we examined DILs’ attributions for MILs’ hurtful messages and their perceived agreement with their husbands’ reasoning for the message. Our findings illuminate distress-maintaining and relationship-enhancing attribution biases for MILs’ behaviors, such that DILs who were less satisfied with their MILs tended to make more internal attributions for MIL hurtful behaviors, and more satisfied DILs tended to make more external attributions. The degree to which a DIL believed she and her husband interpreted his mother’s behavior similarly was also important and positively predicted marital satisfaction. Findings addto the growing portrait of in-law communication, offering directions for hurtful messages and attribution theorizing in the in-law context. 相似文献
This article offers a variety of culturally responsive approaches and activities so as to better know and understand our students' diverse cultural and linguistic backgrounds. These methods will not only help to make more equitable classrooms where we make meaningful connections with our students—but also yield useful data so as to inform our yearly curriculum and instruction. 相似文献
Background: In the U.S. college/university setting, physical activity courses are often offered as part of the general education program, where students earn college credits towards the completion of their degree program. These courses are typically taught by graduate teaching assistants (GTAs), who face several challenges in instructing undergraduate students. Often, GTAs are thrust into their roles without the preparation that traditional teachers receive as customary with education degrees. Literature on need supportive teacher training, as part of self-determination theory, indicates that teachers including GTAs, can be successfully trained to meet the needs of their students regardless of years of previous experience. Presently, there is little information on the impact of such a training program from the perspective of the GTAs participating in the program.
Purpose: The aim of this study is to provide in-depth perspectives on need supportive training through examination of GTAs reflections of the training process.
Participants and setting: Fourteen GTAs from a university physical activity and healthful living program were recruited for this study, but two dropped out. All participants taught one of the following courses: aerobics, basketball, body conditioning, bowling, flag football, golf, racquetball, soccer, tennis, ultimate frisbee, volleyball, or yoga.
Data collection: Teaching reflections were written by participants at the end of a year-long training program.
Data analyses: Written reflections completed by the GTAs were analyzed via content analysis. Data were organized by how strategies were implemented, most/least successful use of the strategies, and adherence to the training. Once organized, the data was examined by two different researchers independently and themes were shared with participants as part of the member checking process. Searches for negative cases were utilized during the analysis process as well.
Findings: Across the data, it was determined that the GTAs felt the training to be beneficial, influencing much of how they worked with students. Results suggested that GTAs found several ways to implement the reviewed need supportive teaching strategies, including giving students the choice of activities and group membership. They were also able to better respond to students’ negative affect and give explanatory rationales. Goal setting was a consistently used strategy by the GTAs; however, it was cited as one of the least successful strategies due to the inability to effectively follow-up on the goals made during classes with the students. Additionally, it was noted that the GTAs had difficulties with devising their own ways of implementing the strategies and relied heavily on the examples that were provided during their training sessions.
Conclusion: In better understanding, the perceptions of GTAs who engage in need supportive training programs, researchers can better gauge the effectiveness of such programs and how they can be improved. Future research should focus on how to help GTAs to engage in more creative ways of using need supportive teaching strategies in physical activity environments. 相似文献
Biomechanics education is a vital component of kinesiology, sports medicine, and physical education, as well as for many biomedical engineering and bioengineering undergraduate programmes. Little research exists regarding effective teaching strategies for biomechanics. However, prior work suggests that student learning in undergraduate physics courses has been aided by using the Just-in-Time Teaching (JiTT). As physics understanding plays a role in biomechanics understanding, the purpose of study was to evaluate the use of a JiTT framework in an undergraduate biomechanics course. This two-year action-based research study evaluated three JiTT frameworks: (1) no JiTT; (2) mathematics-based JiTT; and (3) concept-based JiTT. A pre- and post-course assessment of student learning used the biomechanics concept inventory and a biomechanics concept map. A general linear model assessed differences between the course assessments by JiTT framework in order to evaluate learning and teaching effectiveness. The results indicated significantly higher learning gains and better conceptual understanding in a concept-based JiTT course, relative to a mathematics-based JiTT or no JiTT course structure. These results suggest that a course structure involving concept-based questions using a JiTT strategy may be an effective method for engaging undergraduate students and promoting learning in biomechanics courses. 相似文献
