Investigative- and cooperative-based learning strategies have been used effectively in a variety of classrooms to enhance student learning and engagement. In the General Microbiology laboratory for juniors and seniors at James Madison University, these strategies were combined to make a semester-long, investigative, cooperative learning experience involving culture and identification of microbial isolates that the students obtained from various environments. To assess whether this strategy was successful, students were asked to complete a survey at the beginning and at the end of the semester regarding their comfort level with a variety of topics. For most of the topics queried, the students reported that their comfort had increased significantly during the semester. Furthermore, this group of students thought that the quality of this investigative lab experience was much better than that of any of their previous lab experiences.  相似文献   

Comparison of kinematics in skilled and unskilled arms of the same recreational baseball players     

S. Gray  S. Watts  D. Debicki 《Journal of sports sciences》2013,31(11):1183-1194

Abstract

We examined mechanisms of coordination that enable skilled recreational baseball players to make fast overarm throws with their skilled arm and which are absent or rudimentary in their unskilled arm. Arm segment angular kinematics in three dimensions at 1000 Hz were recorded with the search-coil technique from the arms of eight individuals who on one occasion threw with their skilled right arm and on another with their unskilled left arm. Compared with their unskilled arm, the skilled arm had: a larger angular deceleration of the upper arm in space in the forward horizontal direction; a larger shoulder internal rotation velocity at ball release (unskilled arms had a negative velocity); a period of elbow extension deceleration before ball release; and an increase in wrist velocity with an increase in ball speed. It is suggested that some of these differences in arm kinematics occur because of differences between the skilled and unskilled arms in their ability to control interaction torques (the passive torque at one joint due to motion at adjacent joints). It is proposed that one reason unskilled individuals cannot throw fast is that, unlike their skilled counterparts, they have not developed the coordination mechanisms to effectively exploit interaction torques.  相似文献   

Adjusting athletes' body mass index to better reflect adiposity in epidemiological research

Abstract

The aim of the present study was to identify when body mass index (BMI) is unlikely to be a valid measure of adiposity in athletic populations and to propose a simple adjustment that will allow the BMI of athletes to reflect the adiposity normally associated with non-athletic populations. Using data from three previously published studies containing 236 athletes from seven sports and 293 age-matched controls, the association between adiposity (sum of 4 skinfold thicknesses, in millimetres) and BMI was explored using correlation, linear regression, and analysis of covariance (ANCOVA). As anticipated, there were strong positive correlations (r = 0.83 for both men and women) and slope parameters between adiposity and BMI in age-matched controls from Study 1 (all P < 0.001). The standard of sport participation reduced these associations. Of the correlations and linear-regression slope parameters between adiposity and BMI in the sports from Studies 2 and 3, although still positive in most groups, less than half of the correlations and slope parameters were statistically significant. When data from the three studies were combined, the ANCOVA identified that the BMI slope parameter of controls (5.81 mm · (kg · m^?2)^?1) was greater than the BMI slope parameter for sports (2.62 mm · (kg · m^?2)^?1) and middle-distance runners (0.94 mm · (kg · m^?2)^?1) (P < 0.001). Based on these contrasting associations, we calculated how the BMI of athletes can be adjusted to reflect the same adiposity associated with age-matched controls. This simple adjustment allows the BMI of athletes and non-athletes to be used with greater confidence when investigating the effect of BMI as a risk factor in epidemiological research.  相似文献   

Validity of the New Lifestyles NL-1000 Accelerometer for Measuring Time Spent in Moderate-to-Vigorous Physical Activity in School Settings     

David McMinn  David A. Rowe  Michelle Stark  Louise Nicol 《Measurement in physical education and exercise science》2013,17(2):67-78

Current interest in promoting physical activity in the school environment necessitates an inexpensive, accurate method of measuring physical activity in such settings. Additionally, it is recognized that physical activity must be of at least moderate intensity in order to yield substantial health benefits. The purpose of the study, therefore, was to determine the validity of the New Lifestyles NL-1000 (New Lifestyles, Inc., Lee's Summit, Missouri, USA) accelerometer for measuring moderate-to-vigorous physical activity in school settings, using the Actigraph GT1M (ActiGraph, Pensacola, Florida, USA) as the criterion. Data were collected during a cross-country run (n = 12), physical education (n = 18), and classroom-based physical activities (n = 42). Significant and meaningful intraclass correlations between methods were found, and NL-1000 estimates of moderate-to-vigorous physical activity were not meaningfully different from GT1M-estimated moderate-to-vigorous physical activity. The NL-1000 therefore shows promising validity evidence as an inexpensive, convenient method of measuring moderate-to-vigorous physical activity in school settings.  相似文献

Literacy skills of adults with intellectual disabilities in two community‐based day programs     

Louise Young  Karen B. Moni  Anne Jobling  Christinavan E. Kraayenoord 《International Journal of Disability, Development & Education》2004,51(1):83-97

There is limited information available related to the literacy skills of adults with intellectual disabilities. In this project, information was collected about the contexts, current practices, and clients' abilities in literacy in two community‐based disability service programs. Individual assessments were undertaken to collect details of the current literacy levels of adults with intellectual disabilities in day program settings. These assessments focused on receptive language, reading at the letter, word and sentence level, writing vocabulary and connected text, and literacy preferences. Audits were also conducted related to the provision of opportunities for clients accessing these services to engage with literacy including environmental print. Structured day program activities were observed to gather information about current literacy teaching and learning. Implications of the research findings and suggestions for provision of literacy education in these settings are discussed.  相似文献

‘They never go off the rails like other ethnic groups’: teachers’ constructions of British Chinese pupils’ gender identities and approaches to learning     

Louise Archer  Becky Francis 《British Journal of Sociology of Education》2005,26(2):165-182

This paper examines the ways in which British Chinese pupils are positioned and represented within the popular/dominant discourse of teachers working in London schools. Drawing on individual interviews from a study conducted with 30 teachers, 80 British Chinese pupils and 30Chinese parents, we explore some of the racialised, gendered and classed assumptions upon which dominant discourses around British Chinese boys and girls are based. Consideration is given, for example, to teachers’ dichotomous constructions of British Chinese masculinity, in which British Chinese boys were regarded as ‘naturally’ ‘good’ and ‘not laddish’, compared with a minority of ‘bad’ British Chinese boys, whose laddishness was attributed to membership of a multiethnic peer group. We also explore teachers’ constructions of British Chinese femininity, which centred around remarkably homogenised representations of British Chinese girls as ‘passive’ and quiet, ‘repressed’, hard‐working pupils. The paper discusses a range of alternative readings that challenge popular monolithic and homogenising accounts of British Chinese masculinity and femininity in order to open up more critical ways of representing and engaging with British Chinese educational ‘achievement’.  相似文献   

Students’ strategies for learning identities as industrial workers in a Swedish upper secondary school VET programme     

Lisa Ferm  Daniel Persson Thunqvist  Louise Svensson 《Journal of Vocational Education & Training》2018,70(1):66-84

The aim of this article is to investigate the learning strategies vocational students use to become part of a work community, and how these strategies are related to the formation of a vocational identity at the workplace. Conducting qualitative interviews, data were collected from 44 industrial programme students from six upper secondary schools. The findings revealed five recurrent strategies used by the students for learning vocational identities as industrial workers. The students took individual responsibility for their own learning, asked questions to gain deeper vocational knowledge, searched for role models in the work community, positioned themselves as a resource to the work community, understood and used humour and jokes in order to become a member of the community. The conclusion is that the students actively develop learning strategies to adapt their behaviour to the norms and ideals of the industrial work community. In the process of develop the vocational identities as industrial workers, the students’ vocational habitus is transformed to better fit the industrial work community. The integration of the notions of agency and habitus demonstrates the dynamic nature of students’ participation in work communities; simultaneously, the students reproduce social structures that promote vocational identities.  相似文献
