This article complicates dominant instrumentalist understandings of international student motivation by focusing on Chinese female tertiary students in Australia. Based on longitudinal fieldwork with 56 such students, it analyses motivations described by students and their parents in interviews, showing that these far exceed instrumentalism and engage tactics of both gendered risk management and cosmopolitan self-fashioning. Discussion of the gendered risks in post-socialist China that students seek to mitigate through study abroad illustrates the complexity of students’ motivations, and underlines the limitations of western European sociological theories of risk society which assume that gender inequality tends to decrease in late modernity.  相似文献

This study aimed to develop and investigate the validity and reliability of the Mentor Teacher Role Inventory (MTRI). A total of 1843 student teachers in the Distance English Teacher Training Program participated in the study. The 58 items of the Mentor Teacher Role Inventory underwent principal factor analysis, which revealed nine factors relating to mentorship and explained 52.971% of the total variance. The KMO value of the MTRI was calculated as .968. The Cronbach's alpha was .951. These results indicated that a reliable and valid MTRI could be used for both the distance English teacher training programme and other distance teacher education programmes.  相似文献

The purpose of this study is to examine the effects of ‘environmental chemistry’ elective course via Technology-Embedded Scientific Inquiry (TESI) model on senior science student teachers’ (SSSTs) conceptions of environmental chemistry concepts/issues, attitudes toward chemistry, and technological pedagogical content knowledge (TPACK) levels. Within one group pre-test–post-test design, the study was conducted with 117 SSSTs (68 females and 49 males—aged 21–23 years) enrolled in an ‘environmental chemistry’ elective course in the spring semester of 2011–2012 academic-years. Instruments for data collection comprised of Environmental Chemistry Conceptual Understanding Questionnaire, TPACK survey, and Chemistry Attitudes and Experiences Questionnaire. Significant increases in the SSSTs’ conceptions of environmental chemistry concepts/issues, attitudes toward chemistry, and TPACK levels are attributed to the SSSTs learning how to use the innovative technologies in the contexts of the ‘environmental chemistry’ elective course and teaching practicum. The study implies that the TESI model may serve a useful purpose in experimental science courses that use the innovative technologies. However, to generalize feasibility of the TESI model, it should be evaluated with SSSTs in diverse learning contexts.  相似文献

The aim of this study was to compare time-motion indicators during judo matches performed by athletes from different age groups. The following age groups were analysed: Pre-Juvenile (13-14 years, n = 522), Juvenile (15-16 years, n = 353); Junior (19 years, n = 349) and Senior (>20 years, n = 587). The time-motion indicators included: Total Combat Time, Standing Combat Time, Displacement Without Contact, Gripping Time, Groundwork Combat Time and Pause Time. Analysis of variance (ANOVA) one-way and the Tukey test, as well as the Kruskal-Wallis test and Mann-Whitney (for non-parametric data), were conducted, using P < 0.05 as significance level. The results showed that all analysed groups obtained a median of 7 (first quantile - 3, third quantile - 12) sequences of combat/pause cycles. In total time of combat, the result was: for Total Combat Time, Standing Combat Time and Gripping Time: Pre-Juvenile and Senior were significantly longer than Juvenile and Junior. Considering Displacement Without Contact, Junior was significantly longer than all other age groups. For Groundwork Combat Time, Senior was significantly longer than all other age groups and Pre-Juvenile was longer than Junior. These results can be used to improve the physiological performance in intermittent practices, as well as technical-tactical training during judo sessions.  相似文献

Recent research efforts (Schmidt et al. in The preparation gap: teacher education for middle school mathematics in six countries, MSU Center for Research in Mathematics and Science Education, 2007) demonstrate that teacher development programs in high-performing countries offer experiences that are designed to develop both mathematical knowledge and pedagogical knowledge. However, identifying the nature of the mathematical knowledge and the pedagogical content knowledge (PCK) required for effective teaching remains elusive (Ball et al. in J Teacher Educ 59:389–407, 2008). Building on the initial conceptual framework of Magnusson et al. (Examining pedagogical content knowledge, Kluwer, Dordrecht, pp 95–132, 1999), we examined the PCK development for two beginning middle and secondary mathematics teachers in an alternative certification program. The PCK development of these two individuals varied due to their focus on developing particular aspects of their PCK, with one individual focusing on assessment and student understanding, and the other individual focusing on curricular knowledge. Our findings indicate that these individuals privileged particular aspects of their knowledge, leading to differences in their PCK development. This study provides insight into the specific aspects of PCK that developed through the course of actual instructional practice, providing a lens for future research in this area.  相似文献
