论高校后勤工作在本科教学水平评估中的作用

普通高等学校本科教学水平评估的主要目的是提高办学质量和办学效益。后勤作为高等学校的重要组成部分,应以此为契机,深刻理解评估工作的意义,认真进行自我评价,扎实做好基础保障和教学服务工作。文章结合实际讨论了高校后勤做好迎评工作的体会和认识。     

高校后勤企业财务管理体制改革探讨

构建后勤企业新的财务管理体制，首先要建立规范的企业集团管理体制，理顺后勤集团内部产权关系；要改变高校对后勤原有的财务管理体制、资产管理方式；要搞好资产的产权界定和评估，规范分离行为；要完善内部合计控制制度，完善监督约束机制。     

The Impact of Sample Size and Other Factors When Estimating Multilevel Logistic Models

The design of research studies utilizing binary multilevel models must necessarily incorporate knowledge of multiple factors, including estimation method, variance component size, or number of predictors, in addition to sample sizes. This Monte Carlo study examined the performance of random effect binary outcome multilevel models under varying methods of estimation, level-1 and level-2 sample size, outcome prevalence, variance component sizes, and number of predictors using SAS software. Mean estimates of statistical power were influenced primarily by sample sizes at both levels. In addition, confidence interval coverage and width and the likelihood of nonpositive definite random effect covariance matrices were impacted by variance component size and estimation method. The interactions of these and other factors with various model performance outcomes are explored.

Lecture attendance is a pivotal factor for improving prospective teachers’ academic performance in Teaching and Learning Mathematics

The value and importance of lectures in higher education is part of a modern education discourse worldwide. This study aims to estimate the importance of lectures for prospective teachers of kindergarten, preschool and early primary school. We analysed academic achievements of prospective teachers who had either mandatorily or voluntarily attended lectures in the subject of teaching and learning mathematics. Students’ examination grades in a maths course with mandatory or voluntary lecture attendance were analysed with a logistic model testing the association between lecture attendance requirement and grades. We show that mandatory lecture attendance (1) more than double the odds of students receiving a pass grade when their situated and tacit knowledge was examined and (2) quadrupled the odds of students achieving the highest grade (pass with distinction) when both their understanding of elementary mathematics and their situated and tacit knowledge of teaching and learning mathematics were examined. Our study provides evidence for a significant positive role of lecture attendance for students acquiring skills in Teaching and Learning Mathematics. While attending lectures students receive situated tacit knowledge of the subject which is otherwise difficult, if not impossible, for them to obtain in a different way. The observed improvement may have an additional positive effect in being a step towards overcoming a maths anxiety, which is otherwise relatively common among prospective teachers.

The impact of attaining the Welsh Baccalaureate Advanced Diploma on academic performance in bioscience higher education

Since the introduction of the Welsh Baccalaureate Advanced Diploma Qualification (WBQ) in 2003, an increasing number of students are applying to higher education institutions (HEIs) with this qualification. The advanced-level WBQ is regarded as equivalent to one General Certificate of Education A-Level (GCE A-Level). This study assesses the impact of attaining the WBQ in addition to three GCE A-Levels on overall university degree performance in comparison to attaining four GCE A-Levels, in three cohorts of undergraduate students (Year 1?=?318, Year 2?=?280, Year 3?=?236) studying Biosciences from 2005 to 2011 at a UK HEI. Binary logistic regression was used to compare the academic attainment of students who had achieved four GCE A-Levels to those who had achieved three GCE A-Levels in addition to the WBQ. Comparisons were also made between students who had achieved three GCE A-Levels and those who had achieved three GCE A-Levels in addition to the WBQ. The results suggest that students who achieved the WBQ qualification in its current form, in addition to three GCE A-Levels, performed less well academically in undergraduate studies than those who achieved four GCE A-Levels. Furthermore, this effect was still present when the balance between coursework and examination was considered, and when students who had achieved the WBQ in addition to three GCE A-Levels were compared to students who had achieved three GCE A-Levels.
