ABSTRACT In the UK, higher education (HE) policy discourse over the past 60 years has advocated flexible part-time HE for social mobility, personal development, economic advantage and leisure. However, part-time undergraduate HE in the UK is in steep decline. Against this backdrop, we were interested in how universities promote, or fail to promote, part-time study options today. We built a corpus of 90 UK undergraduate prospectuses for 2018 entry (5,673,799 words). Using a corpus-assisted discourse analysis approach, we found significant mismatch between policy discourse and marketing discourse regarding part-time study. In particular, we found that UK university marketing discourse positions full-time study as the dominant mode of study and writes of part-time study as ‘second-best’. This discourse mismatch is particularly marked when it comes to the elite Russell Group of universities. Viewing the absence of strong promotional discourse relating to part-time study alongside other factors such as increased tuition fees and the rise of global online education platforms adds a new perspective to the decline of flexible part-time undergraduate HE at campus-based universities in the UK. 相似文献

教育创新是社会发展的必然要求,也是学科发展的必然趋势。语文教师要在基础教育改革中扮演重要角色,就必须具备较高的创新素质。创新型教师应该具有现代化的语文教育思想、创新的自信心与责任感、新的人才观、新的学习观、不断进取的探索精神。 相似文献

电视新闻现场报道是一种重要的报道形式 ,因而它越来越多地被记者们所采用。然而目前的许多所谓“现场报道”却并不是真正意义上的“现场报道”。产生这种现象的一个重要原因是记者的口语能力达不到相应的要求。在新闻教育和新闻从业人员中加强口语训练 ,乃是一个亟待解决的问题。 相似文献

Rats were trained on a series of reversals of a successive discrimination in which the percentage of S+ trials ending in food was varied. Changes in the discrimination index occurred more slowly with 50% reinforcement than with 100% reinforcement when the number of training trials was equated across conditions, but were approximately invariant when the conditions were equated with respect to the number of obtained reinforcements. Presentation of free reinforcement during the intertrial intervals reduced the overall rate of discrimination acquisition, but left this invariance unaffected. Invariance in reinforcements necessary to attain acquisition also occurred when different discriminations correlated with different percentages of reinforcement were intermixed within experimental sessions. The failure of the invariance effect to be disrupted by either manipulation suggests that previous accounts of the invariance effect in terms of “comparator” models of conditioning (e.g., Gibbon & Balsam, 1981) are inadequate. 相似文献

This research examines the impact of lecturer-student exchange (student-LMX) on engagement, course satisfaction, achievement, and intention to leave university prematurely for 363 students in one Australian university. Survey and grade point average (GPA) data were collected from domestic undergraduate first- and second-year students and analysed using structural equation modelling. The results indicated that student’s levels of engagement and course satisfaction fully mediated the relationship between student-LMX and intention to leave university, when demographic and socio-economic factors were controlled for. In an era when low student engagement and attrition is often attributed to individual demographic factors, and lecturers are under increasing threat of being replaced by technology, this research offers compelling evidence regarding the role of lecturer-student relationships in enhancing tertiary student outcomes. 相似文献

The dimensions and the materials type limit the performance of fuel cell. The increase of the temperature in electrodes and electrolyte of the cell,is due to the over potential of activation (transfer of load),the over potential Ohmic (resistance of polarization),the over potential of reaction (heat released by the chemical reaction) and the over potential of diffusion. In this paper,we studied the thermo-electrical performance of an intermediate temperature solid oxide fuel cell (IT-SOFC) with electrode supported. The aim of this work is to study this increasing temperature of a single cell of an IT-SOFC under the influence of the following parameters: heat sources,functioning temperature and voltages of the cell,geometric configuration and materials type. The equation of energy in one dimension is numerically resolved by using the method of finite volumes. A computing program (FORTRAN) is developed locally for this purpose in order to obtain fields of temperature in every element of the cell. 相似文献
