ABSTRACT

Motivation and self-regulation were examined in a sample of community college transfer students enrolled in a 4-year, online university. The relation between motivation and self-regulation and students’ performance was examined, as was the association between these learner characteristics (i.e., motivation and self-regulation) and sociodemographic factors (e.g., marital status, employment status). Motivation was found to be significantly correlated with both semester and cumulative grade point average (GPA), while associations between self-regulation and performance were more limited. Further, motivation was found to be a significant predictor of semester GPA in a model controlling for sociodemographic factors and prior achievement. Motivation and self-regulation were also found to differ according to students’ sociodemographic status. For instance, transfer students with children under 18 were found to have significantly higher levels of motivation than nonparents. Those employed full-time had lower levels of self-regulation than did their nonemployed peers. Implications for further research on community college transfer students and online learning are discussed.  相似文献

Abstract

Although angiogenetic therapy using recombinant growth factors holds much hope for the treatment of ischaemic diseases, there are still many unanswered questions, including the method of administration, the correct dose of these factors, and the duration of the therapeutic approach. Exercise has also been suggested to induce neovascularizaiton in muscles. We evaluated the angiogenetic effects of the intramuscular administration of basic-fibroblast growth factor (b-FGF) and acidic-fibroblast growth factor (a-FGF) in rat heart, compared with rats who exercised daily. In conclusion, both the intramuscular administration of b-FGF and exercise increased significantly angiogenesis in the heart in contrast to the intramuscular administration of a-FGF, which was ineffective.  相似文献

Abstract

Basketball incorporates intense eccentric muscle activity that induces muscle microtrauma and an inflammatory response. This study investigated time-dependent inflammatory and performance responses during a weekly microcycle after a basketball match. Twenty elite-standard players underwent a trial that comprised a match followed by a 6-day simulated in-season microcycle. The trial was preceded by a control condition that did not have a match. Blood sampling and tests of maximal-intensity exercise performance and muscle damage occurred before each condition, immediately after the match and daily thereafter for 6 consecutive days. The match induced marked increases in heart rate, lactate, ammonia, glucose, non-esterified fatty acids and triglycerides. Performance deteriorated for 24–48 h after the match, whereas knee flexor and extensor soreness increased for 48 and 24 h post-match, respectively. Inflammatory (leukocytes, C-reactive protein, creatine kinase activity, adhesion molecules, cortisol, uric acid and cytokines) and oxidative stress (malondialdehyde, protein carbonyls, oxidised glutathione, antioxidant capacity, catalase and glutathione peroxidase) markers increased for ~24 h and subsided thereafter. Reduced glutathione declined for 24 h after exercise. These results suggest that a basketball match elicits moderate and relatively brief (~24–48 h) inflammatory responses, is associated with marked but short-lived performance deterioration, but is less stressful than other intermittent-type sports.  相似文献

Parental involvement and communication are essential for language development in young children. However, hearing parents of deaf children face challenges in providing language input to their children. This study utilized the largest national sample of deaf children receiving cochlear implants, with the aim of identifying effective facilitative language techniques. Ninety‐three deaf children (≤ 2 years) were assessed at 6 implant centers prior to and for 3 years following implantation. All parent–child interactions were videotaped, transcribed, and coded at each assessment. Analyses using bivariate latent difference score modeling indicated that higher versus lower level strategies predicted growth in expressive language and word types predicted growth in receptive language over time. These effective, higher level strategies could be used in early intervention programs.  相似文献

There is a strong relationship between experiencing violence and participating in behaviors that increase the risk of contracting sexually transmitted infections. Sexual health education (SHE) tailored to the unique needs of female survivors of violence is needed. This paper presents findings from 40 surveys and 33 accompanying interviews with stakeholders representing 31 agencies in the violence advocacy community in Arkansas to investigate the feasibility, acceptability, and perceived need of a SHE program for female survivors of violence. Data also explore the role and preferences of community agencies in the design and implementation of such a program. Interviews with stakeholders revealed three themes: intervention concerns, content, and structure.  相似文献

RE in Russia has been recently introduced as a compulsory regular school subject during the last year of elementary school. The present study offers a critical analysis of the current practice of Russian RE by comparing it with RE in Sweden, Denmark and Britain. This analysis shows that Russian RE is ambivalent. Although it is based on a non-confessional religious studies approach, Russian RE also serves the interests of the Russian Orthodox Church, which aims to educate students into Orthodox Christianity, as well as the interests of the Russian state itself, which turns RE in a kind of citizenship education focusing on the patriotic upbringing of students.  相似文献

While recent scholarship has suggested that colleges and universities have an obligation to help cultivate students’ creativity, existing evidence suggests that this priority is infrequently and imperfectly realized in practice. In order to further examine the potential prevalence of this gap, the present study conducted a qualitative analysis of all publicly available undergraduate course outlines from one Canadian university for the 2013–2014 academic year. Using a modified version of an existing analytical tool, we scrutinized syllabi from across academic disciplines for explicit and implicit references to student creativity, understanding these texts as significant locations at which meanings about teaching and learning are enacted. Based on this analysis, we argue that creativity occupies a relatively circumscribed position in many ways – particularly in the Science, Technology, Engineering, and Mathematics disciplines, but may nonetheless be fostered through the deployment of relevant activities. Implications for the development of student creativity are considered.  相似文献

This paper draws upon a broader piece of research on assessment in higher education, particularly focusing on issues regarding the fairness and effectiveness of the assessment methods and their implications for the learning process. The perceptions of undergraduate students are analysed taking into account the effectiveness and fairness of both traditional and learner-centred assessment methods, as well their influence on the learning process. In total, 624 students participated in this study in five Portuguese Public Universities in different areas of knowledge and programmes. Data were collected through questionnaires. Findings suggest that assessment is seen as more effective and fairer when it is done through the use of learner-centred assessment methods rather than by traditional assessment (e.g. written tests or exams). The students also claim that they devote more time to study when assessment is performed through learner-centred assessment methods than by traditional ones. The most used assessment methods are written tests and oral presentations in group. However, differences in the programmes were identified as well as differences according to gender. Implications of the findings for assessment and for the teaching and learning process are discussed.  相似文献

Individual differences in young children's social cognition were examined in 128 urban preschoolers from a wide range of backgrounds. comprehensive assessments were made of children's false-belief understanding, emotion understanding, language abilities, and family background information was collected via parent interview. Individual differences in children's understanding of false-belief and emotion were associated with differences in language ability and with certain aspects of family background, in particular, parental occupational class and mothers' education. The number of siblings that children had did not relate to their social cognition. Individual differences in false-belief and emotion understanding were correlated, but these domains did not contribute to each other independently of age, language ability, and family background. In fact, variance in family background only contributed uniquely to false-belief understanding. The results suggest that family background has a significant impact on the development of theory of mind. The findings also suggest that understanding of false-belief and understanding of emotion may be distinct aspects of social cognition in young children.  相似文献
