Despite the heavy reliance on textbooks in college courses, research indicates that college students enrolled in first‐year science courses are not proficient at comprehending informational text. The present study investigated a reading comprehension questioning strategy with origins in clinical research based in elaboration interrogation theory, which outlines how to encourage readers to recall relevant background knowledge while reading text materials. The theory suggests that the strategy increases the likelihood that readers will integrate what they read with what they know to make new knowledge. The setting for the study more closely resembled classroom conditions compared to similar studies in the past. Unlike previous studies on reading comprehension, students read a challenging passage from the textbook used in a science course in which they were enrolled. In addition, the text was longer than that used in clinical research. The college students (n = 294) in this study were randomly assigned to either a questioning strategy treatment or a rereading placebo‐control. While reading, treatment students were presented with statements taken from regular intervals in their textbook (about every 150 words) and asked a simple why question about each of these statements. Significant differences were found favoring elaborative interrogation theory and its question strategy treatment over the placebo‐control in terms of science comprehension even after significant estimated predictors of prior knowledge and verbal ability were statistically controlled or accounted for by removing the statistical contributions of these predictors to the main effects. © 2010 Wiley Periodicals, Inc.

Bioelectrical impedance vector-analysis (BIVA) describes cell-mass, cell function and hydration status of an individual or a group. The goal of the present investigation was to provide bioelectrical impedance data for 525 male road cyclists (155 professionals, 79 elite, 59 elite-youth, and 232 amateurs) at the time of their optimal performance level. Data were plotted on the resistance-reactance (R-Xc) graph to characterize cyclists group vectors using BIVA. Compared to the general male population, the mean vector position of the road cyclists indicates a higher body cell mass (BCM) and phase angle (p<0.001). The vector position of the high-performance, compared to the amateur cyclists showed similar patterns with higher BCM and phase angles and higher reactance values for the high-performance athletes (p<0.001). The bio-impedance data were used to calculate the 50%, 75%, and 95% tolerance ellipses of each group of cyclists. The characteristic vector positions of the road cyclists indicate normal hydration and greater muscle mass and function of the high-performance cyclists compared to amateur cyclists and the normal population. The cyclists specific tolerance ellipses, particularly the high-performance cyclists might be used for classifying a cyclist according to the individual vector position and to define target vector regions for lower level cyclists. 相似文献

AbstractThroughout the late nineteenth century, many women turned their talents to improving horse sports as authors, equipment inventors, clothing designers, and trainers. Although these were male-dominated domains, many women quickly realized that there was a demand for their expertise and innovation as men did not ride side-saddle nor understand it. Thus, women became writers of sporting manuals (non-fiction) and sporting novels (fiction), which aided other women in improving and understanding riding and hunting. They also made significant innovations in equipment construction, such as saddles and stirrups, and clothing design, in fashioning specialized sporting garments. Finally, they also became riding instructors, training other women to ride and hunt well. Though some women forged ahead for their own benefit, seeking profit out of writing or teaching, there were also many other women who pursued new ideas to improve horse sports as a whole and encourage greater, safer, and better participation for other women. In these ways, female equestrians consciously acted as sporting entrepreneurs and are significant but underappreciated agents of change not only for equestrianism but for larger social, sartorial, and sporting transformations. 相似文献

ABSTRACTThe aim of this study was to assess the reliability and validity of the bar-mounted PUSH BandTM 2.0 to determine peak and mean velocity during the bench press exercise with a moderate (60% one repetition maximum [1RM]) and heavy (90% 1RM) load. We did this by simultaneously recording peak and mean velocity using the PUSH BandTM 2.0 and three-dimensional motion capture from participants bench pressing with 60% and 90% 1RM. We used ordinary least products regression to assess within-session reliability and whether the PUSH BandTM 2.0 could accurately predict motion capture velocity. Results showed that PUSH BandTM 2.0 and motion capture peak and mean velocity reliability was acceptable with both loads. While there was a tendency for the PUSH BandTM 2.0 to slightly overestimate peak and mean velocity, there was no fixed bias. However, mean velocity with 60 and 90% 1RM demonstrated proportional bias (differences between predicted and motion capture values increase with magnitude). Therefore, PUSH BandTM 2.0 peak velocity with 60 and 90% 1RM is valid, but mean velocity is not. 相似文献

Abstract The purpose of this investigation was to determine if differences in the tendency to exhibit social loafing is a function of achievement-goal orientation and identifiability. Ninety-six males drawn from 10th-grade physical education classes responded to the Task and Ego Orientation in Sport Questionnaire (Duda, 1992) prior to completing a 30-meter sprint task under three separate conditions: as an individual, in a team with individual performance identified, and in a team with individual performance not identified. Following a median split of the task and ego values reported, subjects were divided into high and low groups for both orientations. Sprint times were compared by means of a 2 × 2 × 3 ANOVA (task x ego x sprint condition) with repeated measures on the third factor. Findings revealed that individuals with a combined low task/high ego orientation were significantly slower in the nonidentifiable team condition than in the other two conditions, whereas high-task/low-ego-oriented individuals demonstrated consistent performance across all three conditions. While confirming that identifiability of performance is an important situational variable, the findings suggest that the dispositional factor of achievement orientation may interact to provide a more detailed explanation of the social loafing phenomenon. 相似文献

Patterns of doctoral study and subsequent career progress were compared for 756 men and women doctoral graduates in education at a research university from two six-year periods, one before and one after a rapid nation-wide increase in the percentage of women doctorates. Despite advantages relative to men in admission, financial support and full-time study, women doctorates of both periods had achieved less career progress than men but held similarly positive perceptions concerning career impact of the degree. Work experience prior to doctoral study strongly predicted career progress for both genders. Thus, affirmative action may have positively affected the careers of recent women doctorates who were younger and who began study with less established careers than women doctorates prior to 1970. 相似文献

The article examines the construct of happiness within the context of counseling and holistic health (body, mind and spirit).
It discusses happiness as a goal of counseling as reflected in selected counseling theories that focus on humanistic principles,
holistic health, positive psychology, personal growth and the client’s intentional choice-making in life. Moreover, the article
considers within-cultural and cross-cultural implications of happiness, and presents recommendations for counseling professionals
who counsel clients or train future counselors. 相似文献

Towards a research training curriculum: What, Why, How, Who? 总被引:3,自引:0,他引:3
Our purpose in this paper is to investigate the ways in which the work of research higher degree supervision is being reshaped from within and outside universities. Our interest is in the means by which new ‘content’ and ‘process’ knowledge — and thus a new set of pedagogical tasks and relationships — are being configured in the field of higher degree research. The outcomes of research training have traditionally been products of a one-on-one supervisory relationship, that is, academic apprentice-to-disciplinary mentor. This is especially the case in the fields of arts/humanities. Any ‘curriculum’ necessary to such a model has been both implicit and at the discretion of the disciplinary ‘master’. 相似文献

Teachers have a central role in developing new learning models in schools. This paper describes a study that explored teachers’ confidence and competence in using Information and Communication Technologies (ICT) as they participated in an ICT development project conducted by an Australian education system in 12 primary schools. The project aimed to develop ICT integrated teaching practices by providing in‐class equipment and teacher professional development in ICT use, curriculum development and teaching strategies. The study used qualitative data from teacher records of Professional Development and Action Learning to identify three of four stages proposed to describe teachers’ ICT learning. Teachers moved from gaining basic ICT skills, to conducting ICT‐focused lessons and eventually appropriate ICT integration. Teachers who progressed to the third stage were able to exploit additional learning opportunities and begin to make fundamental changes to their pedagogy, but needed more time to reach the final stage of challenging existing pedagogical structures. 相似文献
