Developing a generic review framework to assure capstone quality

Within the higher education context, capstone units can be viewed as a significant means of assuring intended learning outcomes for programmes. They provide students with the opportunity to consolidate and apply prior and new disciplinary learning, as well as employability skills and graduate attributes. This paper describes the first stage of an initiative in a regional, Australian university to develop a capstone quality review framework that can be applied across disciplines. A deductive, thematic analysis of relevant literature, guides and institutional strategic documents using a constant comparison method was used to develop a collectively agreed upon set of capstone quality domains and related criteria. These would enable reviewers to assess whether capstone curricula were fit-for-purpose. Capstone domains and criteria were validated and revised using a multi-stage, moderated review of 10 capstone units. This validation process affirmed that to avoid issues with reviewer inter-rater reliability, future use of our framework should emphasise calibrating reviewer interpretation to ensure greater levels of shared understanding of underlying concepts. It further suggested the desirability of incorporating aspects of teacher self-assessment, teacher feedback and student results. Provided these findings are accounted for, we conclude that the proposed capstone review domains and criteria could be used for quality review and enhancement, or capstone benchmarking processes, regardless of discipline area.     

Programme Quality Assessment by the Implication of Variable Entry Qualifications on Students' Performance

Since its inception 30 years ago, the then Department of Engineering Science, Institut Teknologi MARA (ITM) was given the responsibility of preparing all the students in the first year engineering programmes by giving enough knowledge in basic science and mathematics. The nation's vision to become a fully‐industrialised economy by the year 2020 required all institutes of higher learning (IHLs) in Malaysia to increase their intake of students in the science and technology courses, especially in engineering. However, at the upper secondary education level, students have the freedom to choose between the science‐based or non‐science combination of subjects. This has led to a dearth of science‐based students enrolling in IHLs. Because ITM believes that it is possible to educate individuals from various backgrounds, the engineering courses are open to students with a variety of academic qualifications. Special bridging courses were designed and created for such students since late 1996. The success or failure of the new courses can be assessed after the students have gone through the proper first year engineering courses which consist of Mathematics, Physics and Chemistry. This paper reports on a pilot study on the pioneer groups of students with variable entry qualifications to assess the effectiveness of the courses. The study involved the analysis of the students’ examination results as a performance indicator, and it was found that the bridging programme for non‐science students needed to be redesigned. It is also proposed that to improve the quality of the programme, and hence students’ performance, a regular review be conducted, student support activities be continued and to expand the use of self‐study materials.     

巴基斯坦高等学校设置制度:缘起、程序及标准

在巴基斯坦现行高等教育行政管理机构及组织体系下,巴基斯坦高等学校设置制度的构建缘起、设置程序及标准具有一定的特色.研究发现,巴基斯坦高等学校设置程序围绕申请、审核、考察、赋权等四个环节进行,具备系统的设置标准,涵盖师资队伍建设、设备场地规范、经费使用、管理若干方面.巴基斯坦高等学校设置制度较为完备,符合本国国情,利益主体均衡,标准刚柔相济,但也存在重硬件、轻科研,未能为高等教育国际化纵深发展预留对接平台,以及“一刀切”色彩过重等问题.     

Optimizing search results for human learning goals

While past research has shown that learning outcomes can be influenced by the amount of effort students invest during the learning process, there has been little research into this question for scenarios where people use search engines to learn. In fact, learning-related tasks represent a significant fraction of the time users spend using Web search, so methods for evaluating and optimizing search engines to maximize learning are likely to have broad impact. Thus, we introduce and evaluate a retrieval algorithm designed to maximize educational utility for a vocabulary learning task, in which users learn a set of important keywords for a given topic by reading representative documents on diverse aspects of the topic. Using a crowdsourced pilot study, we compare the learning outcomes of users across four conditions corresponding to rankings that optimize for different levels of keyword density. We find that adding keyword density to the retrieval objective gave significant learning gains on some topics, with higher levels of keyword density generally corresponding to more time spent reading per word, and stronger learning gains per word read. We conclude that our approach to optimizing search ranking for educational utility leads to retrieved document sets that ultimately may result in more efficient learning of important concepts.     

Endophytes from medicinal plants and their potential for producing indole acetic acid,improving seed germination and mitigating oxidative stress

Medicinal plants have been used by marginal communities to treat various ailments. However, the potential of endophytes within these bio-prospective medicinal plants remains unknown. The present study elucidates the endophytic diversity of medicinal plants (Caralluma acutangula, Rhazya stricta, and Moringa peregrina) and the endophyte role in seed growth and oxidative stress. Various organs of medicinal plants yielded ten endophytes, which were identified as Phoma sp. (6 isolates), Alternaria sp. (2), Bipolaris sp. (1), and Cladosporium sp. (1) based on 18S rDNA sequencing and phylogenetic analysis. The culture filtrates (CFs; 25%, 50%, and 100% concentrations) from these endophytes were tested against the growth of normal and dwarf mutant rice lines. Endophytic CF exhibited dose-dependent growth stimulation and suppression effects. CF (100%) of Phoma sp. significantly increased rice seed germination and growth compared to controls and other endophytes. This growth-promoting effect was due to the presence of indole acetic acid in endophytic CF. The gas chromatography/mass spectrometry (GC/MS) analysis showed the highest indole acetic acid content ((54.31±0.21) μmol/L) in Bipolaris sp. In addition, the isolate of Bipolaris sp. exhibited significantly higher radical scavenging and anti-lipid peroxidation activity than the other isolates. Bipolaris sp. and Phoma sp. also exhibited significantly higher flavonoid and phenolic contents. The medicinal plants exhibited the presence of bio-prospective endophytic strains, which could be used for the improvement of crop growth and the mitigation of oxidative stresses.     

Competence and usage of Web 2.0 technologies by higher education faculty

Literature on Web 2.0 experiences of higher education faculty in developing countries such as Pakistan is very limited. An insight on awareness and practices of higher education faculty with these tools can be helpful to map strategies and plan of action for adopting latest technologies to support teaching–learning processes in higher education of such countries. This survey study was aimed to examine the competence and practices of higher education faculty in Pakistan with Web 2.0 technologies such as blogs, Wikis, Google Docs, Skype, Flickr, YouTube, and social networks. The study was also focused to look for what type of role faculty play while using these tools; and to find whether any significant differences in terms of age, gender, or academic discipline exist in competence and usage of these tools by the faculty. The data were collected from a sample of 246 university teachers in the spring 2014 semester. The findings of the study indicated that faculty participants reported to use Web 2.0 social tools more frequently than instrumental tools. Similarly, their competence with social tools was higher than their competence with instrumental tools. Additional results indicated that their competence with Web2.0 tools significantly differed with respect to their age, gender, and academic disciplines.     

Ethnic and Racial Identity in Adolescence: Implications for Psychosocial,Academic, and Health Outcomes

The construction of an ethnic or racial identity is considered an important developmental milestone for youth of color. This review summarizes research on links between ethnic and racial identity (ERI) with psychosocial, academic, and health risk outcomes among ethnic minority adolescents. With notable exceptions, aspects of ERI are generally associated with adaptive outcomes. ERI are generally beneficial for African American adolescents' adjustment across all three domains, whereas the evidence is somewhat mixed for Latino and American Indian youth. There is a dearth of research for academic and health risk outcomes among Asian American and Pacific Islander adolescents. The review concludes with suggestions for future research on ERI among minority youth.     

Feeling Good,Happy, and Proud: A Meta‐Analysis of Positive Ethnic–Racial Affect and Adjustment

One point of intersection in ethnic and racial identity research is the conceptual attention paid to how positively youth feel about their ethnicity or race, or positive ethnic–racial affect. This article reports results of a series of meta‐analyses based on 46 studies of this dimension and psychosocial, academic, and health risk outcomes among ethnic and racial minority youth. The overall pattern of results suggests that positive ethnic–racial affect exhibited small to medium associations (r range = |.11| to |.37|) with depressive symptoms, positive social functioning, self‐esteem, well‐being, internalizing, externalizing, academic achievement, academic attitudes, and health risk outcomes. Implications for theory and research about the role of positive ethnic–racial affect among youth growing up in an increasingly diverse society are discussed.
