东南大学理工科高年级学生专业英语教学现状及思考

在过去五十年的发展中,ESP取得了很大成果.东南大学在ESP教学方面也取得长足的进步.然而要形成成熟的ESP教学及考核体系,还需要解决很多问题,同时还要对现有的ESP教学进行适当的改革和改进.本文重点分析东南大学理工科专业ESP教学现状,并建议在ESP教学中采用“合作教学”这一新的教学方法.     

Attitudes,style, and socialization: Predictors of commitment and satisfaction in workgroups

Employees reported attitudes about working in workgroups, their communicator style (relaxed, friendly, and attentiveness), and perceptions of socialization in groups at work. They also reported their commitment to the organization, job satisfaction, and satisfaction with the workplace (ORGSAT). Positive relationships were found between ORGSAT and attitudes, relaxed and friendly styles, and socialization. Multiple Regression analysis demonstrated that socialization best predicted ORGSAT and mediated the relationship between attitudes and friendly style with ORGSAT. Discussion includes the implications for research and the applied value of the findings.     

南京市部分业余体校运动员参训动机分析

运用文献资料、调研、访谈、专家咨询、问卷调查等方法,对南京市部分业余体校314名运动员的参训动机进行调查分析。主要结论：功利性的和世俗性的动机、意愿是受现代社会因素和时代影响。这表明学生及家长对参加竞技体育训练多是为孩子将来的职业考虑,希望通过竞技体育这条道路能够获得更高的荣誉、奖金,或成为一种职业,晋升到社会的中上阶层;应加强爱国主义教育,培养为国争光的荣誉感;鉴于运动员家庭对子女参加竞技体育训练的期望,为其将来的职业选择准备条件。     

Athlete burnout in elite sport: A self-determination perspective

Abstract

The practice of exercise has shown to be beneficial to quality of life of individuals with HIV/AIDS. Thus, the present study analysed the effects of a combined exercise training in persons living with HIV/AIDS. Ten participants participated in the present study. The following variables were analysed: viral load and cell counts for TCD4+/TCD8; maximal oxygen consumption (VO_2max); total mass, absolute fat mass, relative fat mass, absolute lean mass, relative lean mass and body mass index; fasting glycaemia, fasting insulinaemia, homeostatic model assessment (HOMA) index (insulin resistance – homeostatic model assessment (IR-HOMA)); total cholesterol, triglycerides, high-density lipoprotein (HDL), very low-density lipoprotein (VLDL), low-density lipoprotein (LDL); superoxide dismutase, catalase, glutathione peroxidase activities; thiobarbituric acid reactive substances. The combined exercise training consisted of resistance exercises plus aerobic training (60 min · session^?1, three times per week, during 20 weeks). The number of TCD4+ cells, absolute lean mass and relative lean mass, muscle strength for the 45° leg press, seated row and triceps extension, HDL-c levels as well as VO_2max increased post-training. The activity of superoxide dismutase, catalase, glutathione peroxidase enzymes and thiobarbituric acid reactive substances levels were diminished post-training. Finally, it can be concluded that combined exercise training is able to change positively several variables related to health of individuals with HIV/AIDS, mainly the immune system as well as antioxidant mechanisms re-establishment.     

It's more about a lesson than a domain: Lesson-specific autonomy support,motivation, and engagement in math and a second language

Expanding research on the relative impact of different autonomy-supportive strategies employed by teachers across domains, the present study investigated the variation in 4 lesson-specific autonomy-supportive strategies (providing choices, rationales, accepting frustration, and stimulating interests) and 6 aspects of students' motivation and engagement in 2 domains with a repeated measurement design. For 3 weeks, 202 Dutch students from 8 eighth grade classes and 1 ninth-grade class and 12 teachers completed lesson-specific measures at the end of Math and German lessons. Students' perceptions of teachers' autonomy support and their motivation and engagement varied considerably across lessons within a domain (variance at the within-student level ranged from 19% to 51%). In random intercept-random slope models, we found that all autonomy-supportive strategies showed meaningful associations with aspects of students’ motivation and engagement. We did not find substantial domain-dependency in the associations between autonomy support and the outcomes.     

Is cost separate from or part of subjective task value? An empirical examination of expectancy-value versus expectancy-value-cost perspectives

Situated expectancy-value theorists propose that students’ domain-specific expectancies and subjective task values are critical predictors of their achievement and academic choices in those domains. The theory also posits that subjective task values are multidimensional and can be separated into four subcomponents: intrinsic value, attainment value, utility value, and perceived cost. Recently, there have been debates regarding whether perceived cost should be conceptualized and operationalized as part of subjective task value (i.e., the classic expectancy-value perspective), or as a separate construct from subjective task value (i.e., the expectancy-value-cost perspective). In the present study, we explore different structural associations among expectancies, values, and costs using a hierarchical structural equation modeling approach in a high-stakes undergraduate biochemistry course. We use two different measures of perceived cost: one that measured cost as a unidimensional construct and one that measured cost as a multidimensional construct. We also report on data collected both before and after the COVID-19 lockdowns in the United States. Overall, our results suggested that models that supported the expectancy-value perspective and models that supported the expectancy-value-cost perspective both fit the data reasonably well. However, in line with situated expectancy-value theory, we discuss how aspects of the educational context (a high-stakes undergraduate context), the historical context (COVID-19), and measurement of cost (unidimensional vs. multidimensional) may have impacted our findings. Implications for SEVT and future research in this area are discussed.

Students’ age and noncognitive traits predict writing self-efficacy and motivation

The present study explored the relations of students’ age and noncognitive traits (grit, growth mindset, and college self-efficacy) on writing self-efficacy and writing motivation. Participants (N = 457) wrote a short reflection in response to a quote, after which they evaluated similar responses, purportedly written by their peers, that were either exemplary or poor. Participants who read the exemplary essays were less likely to believe they could write as well as their peers (writing self-efficacy) and less likely to write a second essay (writing motivation), demonstrating a discouragement by peer excellence effect. Grit, growth mindset, and college self-efficacy were all positive correlates of writing self-efficacy. Writing self-efficacy, in turn, predicted the willingness to write another essay. Older students reported higher levels of writing self-efficacy and exhibited greater writing motivation. Older students also reported higher levels of grit, college self-efficacy, and growth mindset. A parallel mediation analysis revealed an indirect effect of college self-efficacy on the relation between age and writing self-efficacy. These results suggest that educators should judiciously model the works of students’ exemplary peers and foster noncognitive traits that improve writing self-efficacy. The results also suggest that older students are more receptive to writing.
