Abstract

Our purpose was to determine the aerobic capacities (VO₂max) of a group of black female adolescents (age = 11.4 ? 15.8 years) randomly chosen from a single urban school. Of 91 girls selected, 64 performed an incremental treadmill running test to volitional exhaustion and achieved VO₂max as determined from expired gas measures. Other measures included height (m), weight (kg), and calf and triceps skinfolds (for % fat estimates). Girls were also asked whether they had achieved menarche. VO₂max averaged 37.3 ± 6.2 ml·kg^?1 ·min^?1 and was significantly correlated (r[62]) with height (?.32, p < .01), body mass index (?.63, p < .001), and % fat (?.65, p < .001) but not with age (?.16, p > .10). Postmenarchal girls were significantly taller and older than premenarchal girls. Contrary to previous studies, the girls' VO₂max values were not related to biological age. Our subjects' aerobic capacity values averaged 14% less than those of nonblack U.S. female adolescents previously reported in the literature. This difference in VO₂max was primarily a function of body weight. Study implications support the possibility that overweight in adult black women may originate prior to or during early adolescence. Future longitudinal studies should be designed to investigate the effects of aerobic fitness on cardiovascular risk factor reduction in black adolescent girls.  相似文献   

Physical Performance and Body Form as Related to Physical Activity of College Women     

Patricia R. Conger  Janet A. Wessel 《Research quarterly for exercise and sport》2013,84(4):908-914

Abstract

The problems of this study were to investigate the interrelationship of selected functional and body form measures, and to examine the differences between groups varying in activity levels. The volunteers for the study, 35 college women, were placed in activity groups termed “most active” and “least active” according to their response on an activity history-recall questionnaire. Functional measures included strength and flexibility. Strength was measured with a cable tensiometer and followed the procedures outlined by H. H. Clarke. Flexibility was measured using a Leighton Flexometer. Body form measures included height, weight, percent body fat, fat free body weight, specific gravity, and ponderal index. The range, mean, and standard deviation were computed for all parameters. The Pearson product-moment correlation was employed to determine interrelationships of all variables. Equality of variances among selected parameters was determined by the F test; Cochran-Cox and two sample t tests were used to determine the equality of means among selected parameters in the activity groups. Significant differences at the .05 level were found between the means of weight, fat free body weight, trunk extension flexibility, with the most active group exhibiting higher values. The least active group showed significantly greater shoulder extension flexibility, shoulder inward rotation flexibility, and ankle flexion flexibility.  相似文献   

Frequency Distributions and Standards of Anthropometric and Physical Performance Measures for College Women     

Janet A. Wessel  Richard Nelson  Eva Lou Dillon 《Research quarterly for exercise and sport》2013,84(3):523-533

Abstract

Frequency distributions of the records of a random selection of 200 college women in a nonmajor required program on anthropometric and physical performance measures commonly employed in physical education were compared with best-fitting normal curves for the same data. A table of random numbers was used to secure the sample. A percentile table for the various measurements was constructed. It was concluded that various measurements commonly employed by physical educators give a non-normal distribution. Hence, the obtained distribution as found on various measurements in this study does not warrant treating these data as normal.  相似文献   

TA training: From the TA's point of view     

Janet Lee Jones 《Innovative Higher Education》1993,18(2):147-161

Teaching assistants (TAs) at a major university were surveyed about the annual campus-wide and departmental TA training programs in which they had participated. Responses from these TAs differ markedly from reports based on surveys conducted with the administrators of such training programs. Current training practices can be improved by considering more seriously the TA's point of view.Janet Lee Jones received her B. A. from Pomona College in 1984, concentrating in psychology and Chinese language. Her Ph.D. was awarded in 1989 in the area of cognitive science, with a specialization in psycholinguistics. She has supervised undergraduate and graduate teaching assistants for the past five years. Dr. Jones now teaches a wide variety of psychology courses and interdisciplinary seminars at Fort Lewis College in Durango, Colorado.  相似文献   

Digital Ethics in Social Work Education     

Janet M. Joiner 《Journal of Teaching in Social Work》2019,39(4-5):361-373

ABSTRACT

Attention has been given to the revised National Association of Social Workers (NASW) Code of Ethics that guides social worker use of technology. The revision of the NASW Code of Ethics has signaled a transition in the profession toward ethical online practice using modern techniques and contemporary tools. Practicing social workers are applying these new ethical standards, and many social work educators are doing so when using information and communication technologies with students. However, little research focuses on teaching social work students about digital ethics and professional online conduct. This paper explores the importance of preparing social work students for ethical online behavior.  相似文献   

‘I’m just not that comfortable with technology’: student perceptions of and preferences for Web 2.0 technologies in reflective journals     

Timothy S. O’Connell  Janet E. Dyment 《Journal of Further & Higher Education》2016,40(3):392-411

Encouraging reflective practice and developing reflective practitioners is a goal of many disciplines in higher education. A variety of pedagogical techniques have been used to promote critical reflection including portfolios, narratives and reflective journals. Over the past decade, the use of Web 2.0 technologies with students has been increasingly adopted in higher education settings and many educators have integrated these technologies into reflective assignments. These educators assume that students, who are members of the Net Generation, are technologically savvy and have the ability to integrate the use of Web 2.0 technologies into learning. However, while there have been studies examining the outputs of reflective assignments using Web 2.0 technologies such as blogs, e-portfolios and wikis, there has been little research examining whether or not students actually use technology for these types of assignment if given the choice. Therefore, the purpose of this study was to explore if technology was appropriated or rejected by students for a reflective journaling assignment. Results are based on a content analysis of 42 student journaling assignments and interviews with eight students. Findings suggest that (1) students are not as technologically competent as assumed; (2) students chose to use basic/fundamental technologies (e.g. word processing) because they viewed it as the easiest way to complete the reflective journaling assignment; (3) student perceptions of what makes an assignment ‘good’ influenced their choice to use Web 2.0 technologies; and (4) overarching student perceptions of higher education and learning impacted their appropriation of technology. Implications are discussed and recommendations for both research and practice are made.  相似文献

Further development in social reasoning revealed in discourse irony understanding     

Filippova E  Astington JW 《Child development》2008,79(1):126-138

This study describes the development of social reasoning in school-age children. An irony task is used to assess 5-, 7-, and 9-year-olds' (N= 72) and adults' (N= 24) recursive understanding of others' minds. Guttman scale analysis demonstrates that in order to understand a speaker's communicative intention, a child needs to recognize the speaker's belief, the detection of which depends on the ability to identify the discrepancy between the intended and the expressed meaning. Only children who understand these aspects of mind are able to reflect on the speaker's attitude. Theory of mind and language ability make unique contributions to children's interpretation of irony over and above the impact of age and memory, but attunement to expressive prosody does not.  相似文献   

Cognitive Empathy and the Transition to Independent Graduate Study in Mathematics     

Janet?DuffinEmail author  Adrian?Simpson 《Educational Studies in Mathematics》2005,58(1):121-135

Thirteen Ph.D. students took part in interviews focussed on the nature of their own learning of mathematics. In analysing these interviews an unexpected category emerged concerning the students awareness of others as having particular types of learning goal. In this paper we explore the three levels which we discerned within this category and link them to the notion of cognitive empathy. We suggest that differences in ones own cognitive style are linked to differences in the ability to empathise with those who have alternative learning goals. We also consider how these two features – cognitive style and cognitive empathy – may come to be linked.  相似文献   

Child Readers and the Worlds of the Picture Book     

Adela Baird  Janet Laugharne  Eva Maagerø  Elise Seip Tønnessen 《Children‘s Literature in Education》2016,47(1):1-17

Children as readers of picture books and the ways they respond to, and make meaning from, such texts are the focus of this article, which reports on a small-scale study undertaken in Norway and Wales, UK. The theoretical framing of the research draws on concepts of the multimodal ensemble in picture books and of the reading event as part of a social practice. The research design was developed from the team’s analysis of two texts, Pappa by Svein Nyhus (1998) and What does Daddy Do? by Rachel Bright (2009). Twenty-four children, who were 7 and 8 years old, took part in the study. This was built around two reading events for each book, staged as an immediate response and as a guided response. The data subsequently collected were analysed according to three overarching organisational principles, as book world, real world and play world. For both Daddy and Pappa, the first reading event showed the children’s responses were mainly directed towards exploring the book world. On the second reading event, references to the real world predominated for Daddy, while for Pappa the book world was again dominant. Across both reading events and for both books, the playworld revealed those occasions when the children expanded the meaning of the story, demonstrating an inventive ability to play with the text. Overall, the children’s responses moved fluidly across the three worlds, showing them to be energetically making connections between the reading, their experience of books and their own lives.  相似文献
