This article investigates common understandings and practices of a group of supervisors assessing students during the Teaching Practicum in South Africa. In the light of this context and the need for a constructivist approach to develop students to be able to teach in diverse contexts, the question that the research intends to answer is as follows: What are the common foci of supervisors as reflected in their teaching practicum assessment reports? A randomly mixed sample of 33 narrative reports, taken from 5 supervisors was analysed to gain insight into the assessment report. Findings are presented as five assessment discourses and an argument is presented for the Teaching Practicum assessment to shift towards a student-oriented developmental approach that is neither hierarchical nor judgmental but aims at serving students’ professional development that meets the challenges of culturally diverse societies. 相似文献

As the United Arab Emirates (UAE) moves towards a knowledge-based economy, maximising the participation of the national workforce, especially women, in the transformation process is crucial. Using survey methods and semi-structured interviews, this paper examines the factors that influence women's decisions regarding their degree programme and their attitudes towards science, technology and engineering (STE). The findings point to the importance of adapting mainstream policies to the local context and the need to better understand the effect of culture and society on the individual and the economy. There is a need to increase interest in STE by raising awareness of what the fields entail, potential careers and their suitability with existing cultural beliefs. Also suggested is the need to overcome negative stereotypes of engineering, implement initiatives for further family involvement at the higher education level, as well as the need to ensure a greater availability of STE university programmes across the UAE. 相似文献

This paper examines differences in mathematics achievement among eighth-grade students using a secondary analysis of the data.
The students, who are from Malaysia, had participated in the Trend International Mathematics and Science Study (TIMSS) 1999.
A series of school, home, demographic and socio-economic variables were used to investigate the differences in the mean student
mathematics scores. Evidence from the data shows that gender, the language spoken at home, expected educational level, family
background, and home educational resources and aids have a significant influence on the students’ level of mathematics achievement. 相似文献

The DIIA （Diploma in Investment Analysis） students from the FBM （Faculty of Business Management） were required to undertake several MOF （Mathematic of Finance） courses. The passing rates for all of the MOF courses were good except for one course. There are many factors for this low passing rate phenomenon for this particular MOF course. One of the factors is mathematics anxiety as suggested by Richardson in 1971. As a result, this paper is carried out in order to measure the undergraduates＇ level of mathematics anxiety in general and between genders in this one particular course. The outcome is expected to fill in the gap as study of anxiety in MOF is still lacking. A 30-item MARS （Mathematics Anxiety Rating Scale） is adapted and used in this study, because this course is predominant by complex computations. The Ss （samples） of the study are 119 students who undertook this MOF course during the study semester of December 2008 to April 2009 in UiTM （Universiti Teknologi MARA）. It is expected that the findings will show that the Ss have a considerably high mean for mathematics anxiety; and female students have a higher mean of mathematics anxiety as compared to their male counterparts. The study confirms the expectation of the researchers. In terms of the final and overall results, it was expected that the passing percentage be dominated by the male students. However, at the end of the study, the overall performance of the female students was much better compared to their male counterparts. 相似文献

This paper tests the extent to which social media is shaping civic engagement initiatives to build trust among people and increase trust in their institutions, particularly the government, police and justice systems. A survey of 502 citizens showed that using social media for civic engagement has a significant positive impact on trust propensity and that this trust had led to an increase in trust towards institutions. Interestingly, while group incentives encouraged citizens to engage online for civic matters, it is civic publications through postings on social media that intensify the urge of citizens for civic action to address social issues. Post-hoc analysis via ten interviews with social activists was conducted to further examine their perceptions on trust towards institutions. The overall findings suggest that institutions, in their effort to promote a meaningful and trusting citizen engagement, need to enhance trust among the public by fostering social capital via online civic engagement and closing the public–police disengagement gap. 相似文献

The manipulation of ribosomal RNA (rRNA) extracted from E. coli cells by dielectrophoresis (DEP) has been demonstrated over the range of 3 kHz-50 MHz using interdigitated microelectrodes. Quantitative measurement using total internal reflection fluorescence microscopy of the time dependent collection indicated a positive DEP response characterized by a plateau between 3 kHz and 1 MHz followed by a decrease in response at higher frequencies. Negative DEP was observed above 9 MHz. The positive DEP response below 1 MHz is described by the Clausius-Mossotti model and corresponds to an induced dipole moment of 3300 D with a polarizability of 7.8×10(-32) F m(2). The negative DEP response above 9 MHz indicates that the rRNA molecules exhibit a net moment of -250 D, to give an effective permittivity value of 78.5 ε(0), close to that of the aqueous suspending medium, and a relatively small surface conductance value of ～0.1 nS. This suggests that our rRNA samples have a fairly open structure accessible to the surrounding water molecules, with counterions strongly bound to the charged phosphate groups in the rRNA backbone. These results are the first demonstration of DEP for fast capture and release of rRNA units, opening new opportunities for rRNA-based biosensing devices. 相似文献

This study examined 307 elementary school children’s judgements and reasoning about bullying and other repeated transgressions when school rules regulating these transgressions have been removed in hypothetical school situations. As expected, children judged bullying (repeated moral transgressions) as wrong independently of rules and as more wrong than all the other repeated transgressions. They justified their judgement in terms of harm that the actions caused. Moreover, whereas children tended to judge repeated structuring transgressions as wrong independently of rules (but to a lesser degree than when they evaluated bullying) and justified their judgements in terms of the disruptive, obstructive or disturbing effects that the actions caused, they tended to accept repeated etiquette transgressions by arguing that the acts had no negative effects or simply that the rule had been removed. The findings confirm as well as extend previous social-cognitive domain research on children’s socio-moral reasoning. 相似文献
