Mathematical models for academic webs: Linear relationship or non-linear power law?

Previous studies of academic web interlinking have tended to hypothesise that the relationship between the research of a university and links to or from its web site should follow a linear trend, yet the typical distribution of web data, in general, seems to be a non-linear power law. This paper assesses whether a linear trend or a power law is the most appropriate method with which to model the relationship between research and web site size or outlinks. Following linear regression, analysis of the confidence intervals for the logarithmic graphs, and analysis of the outliers, the results suggest that a linear trend is more appropriate than a non-linear power law.     

Is academic tracking related to gains in learning competence? Using propensity score matching and differential item change functioning analysis for better understanding of tracking implications

This study analyzes gains in cognitive components of learning competence with respect to cohorts based on ability tracking in a Czech longitudinal study. Propensity score matching is used to form parallelized samples of academic and non-academic track students and to eliminate the effect of selective school intake. We applied regression models on the total scores to test for the overall track effect. Furthermore, we analyze scores and gains on the subscores and check for differential item functioning in Grade 6 and in change to Grade 9. While after 3 years, no significant difference between the two tracks was apparent in the total learning competence score, we did, however, find significant differences in some subscores and in the functioning of some items. We argue that item-level analysis is important for deeper understanding of the tracking implications and may provide the basis for more precise evidence-based decisions regarding the tracking policy.     

The Choice of Academic Profession: Class Taste or Personal Opportunities

Abstract

From a historical perspective, it was only in the modern era that the academic profession was favored by the middle and upper classes who came to dominate it. This article shows that, in contemporary China, the pattern of the middle and upper classes dominating the academic profession results from their families having a good early education and access to educational resources, although these advantages decrease through the years of schooling as they are replaced by the effects of the institution. Overall, class differences behind the choice of academic profession result from the differences in economic conditions of families and the inequality in resource distribution at all levels of education, rather than class culture and taste. Therefore, it is essential to implement a strategy to prioritize education, to enrich educational resources for all, and to extend the years of schooling for all. This will not only improve the quality of the workforce, develop personal potential, and cultivate creative and highly talented people, but also help to promote the development of society and steadily build a harmonious and orderly society.     

Investigating academic dishonesty among Chinese undergraduate students: does gender matter?

The high rate of academic dishonesty reported among Chinese college students has created challenges for practitioners in both domestic and Western universities. Following two contrasting yet complementary scholarly approaches, this study explored the relative importance of predictors indicative of students’ intention to cheat (moral attitude, subjective norm and penalty enforcement) and of their educational preparedness for academic integrity (integrity engagement) in explaining academic dishonesty, with an emphasis on gender differences. We administered a questionnaire survey to a sample of 2009 Chinese undergraduate students. The results indicated that moral attitude and integrity engagement were the major predictors, that subjective norm accounted for marginal variations of academic dishonesty, and that the influence of penalty enforcement was insignificant. Some gender differences on both the mean score and effect levels of the four predictors were revealed. The effects of grade, year and area of study on academic dishonesty (and particularly their joint effects with gender) were noteworthy. These findings are discussed relative to the results of prior studies and the Chinese context.     

Improving mathematics results: does teachers’ academic optimism matter? A study of lower secondary schools

Educational effectiveness research has provided evidence about the importance of teacher beliefs and attitudes for teaching and learning. This study builds on the concept of academic optimism, which combines 3 aspects of a teacher’s professional creed: self-efficacy, trust, and academic emphasis. The study explores the functioning of the collective and individual measures of academic optimism in the Czech environment and studies its impact on students’ outcomes. The analyses are based on pilot data from 39 schools, 325 teachers, and 1,316 Grade 9 students and on the data from the Czech Longitudinal Study in Education (CLoSE), covering 163 schools, 1,469 teachers, and 4,798 students. The individual measure was selected for further studies based on 2-level confirmatory factor analysis. Two-level structural equation modelling showed a significant impact of a school’s academic optimism on students’ achievement even after controlling for prior achievement and socioeconomic status at both the student and the school level.     

Why do UK academics become Associate Deans and what are their future career plans?

The role and number of Associate Dean posts in UK universities has grown considerably in recent years. Despite this, relatively little is known about the reasons why individuals take on such roles and how it fits into their career trajectories. The purpose of this article is to explore these issues by drawing on data from the first national study of Associate Deans in the UK. Adopting a two-staged mixed methods approach, data were collected from semi-structured interviews (n = 15) and an online survey (n = 172). The findings suggest that academics take on the role for a number of reasons such as the challenge of working across the University, making a difference to staff and students, or being asked to take it on by a senior member of staff. It is argued that these Associate Dean roles are part of new and emerging academic career pathways within the higher education sector.     

Revisiting the effects of project-based learning on students’ academic achievement: A meta-analysis investigating moderators

Project-based learning is generally considered an alternative to traditional, teacher-led instruction. However, there is a noticeable lack of meta-analyses with regard to determining its overall effects on students' academic achievement, and what study features may moderate the impacts of project-based learning. This study thus performed a meta-analysis to synthesize existing research that compared the effects of project-based learning and those of traditional instruction on student academic achievement. Forty-six effect sizes (comparisons) extracted from 30 eligible journal articles published from 1998 to 2017 were analyzed, representing 12,585 students from 189 schools in nine countries. The results showed that the overall mean weighted effect size (d₊) was 0.71, indicating that project-based learning has a medium to large positive effect on students' academic achievement compared with traditional instruction. In addition, the mean effect size was affected by subject area, school location, hours of instruction, and information technology support, but not by educational stage and small group size.
