The Competence Screening Questionnaire for Higher Education: Adaptable to the needs of a study programme

There is a lively discussion on how to evaluate competence-based higher education in both evaluation and competence research. The instruments used are often limited to course evaluation or specific competences, taking a rather narrow perspective. Furthermore, the instruments often comprise predetermined competences that cannot be adapted to higher education needs. The aim of this paper is to provide a flexible screening instrument into which practitioners/evaluators of study programmes can themselves insert the competences they are interested in, i.e. competences students ought to acquire through their study programme. The present study describes the development of the Competence Screening Questionnaire for Higher Education (CSQ-HE) in different domains of higher education. Results show that the CSQ-HE provides plausible screening information whilst fulfilling evaluation standards. It can be integrated into a higher education institution’s internal quality management system to demonstrate a programme’s legitimacy and enhance competence-based teaching and learning. Strengths, weaknesses and implications for practice are discussed.     

The Effects of Content-Enriched Shared Book Reading Versus Vocabulary-Only Discussions on the Vocabulary Outcomes of Preschool Dual Language Learners

Research Findings: This study compared the effects of content-based shared book-reading instruction versus an explicit vocabulary-only condition on the vocabulary development of preschool dual language learners (DLLs). Using shared book reading as the mode of instruction, we randomly assigned 48 bilingual preschool teachers and 281 Spanish-speaking DLLs from their classrooms at the class level to either a content-enriched interactive book-reading intervention or a thematic content-related vocabulary-only condition. Screened using the preLAS^®, the DLLs were selected for the study based on their scores at the prefunctional and beginning levels of English proficiency. Intervention and comparison bilingual teachers implemented the assigned instructional approach in small groups, for 20 min daily, for 18 weeks. Based on the results of multilevel models, findings indicated pre- to posttest growth on taught words for each instructional condition, with no significant effects on standardized English language measures. Practice or Policy: Results suggest that preschool DLL children benefit from the systematic use of interactive content-enriched shared book-reading vocabulary instruction or direct teaching of content vocabulary when instruction integrates language interaction opportunities with higher cognitive talk and scaffolds. The vocabulary-only routine is a cost-effective approach but may not replace the broader benefits of reading books.     

萝卜硫烷对脑线粒体的影响:机理观点和未来发展方向

有机硫化物萝卜硫烷(SFN)是一种有效的细胞保护剂,在体外和体内实验模型中均可促进抗氧化、抗炎、抗糖化和抗菌作用。因为氧化磷酸化系统的存在,所以线粒体是三磷酸腺苷(ATP)的主要产生部位。同时,线粒体也是具核人体细胞中产生活性氧的主要场所。线粒体损伤在多种人类疾病中起着重要作用,包括神经退行性病变和代谢异常。本文描述和讨论了SFN调节哺乳动物细胞中线粒体功能和动力学的作用和机理,以及其对肿瘤细胞中线粒体促凋亡途径的促进作用。SFN对线粒体的调节作用使得它在一定程度上被认为是一种细胞保护剂。本文还指出了几个需要通过进一步实验解决的问题,即未来的可能研究方向,这可能会对该领域的研究人员具有指导作用。     

SUCCESS IN COLLEGE MATHEMATICS: Comparisons Between Remedial and Nonremedial First-Year College Students

Recent international comparisons show that themathematics achievement of American students is belowthe international average. In response to thissituation, the present study compared first-year college students enrolled in remedial-type mathematicscourses with their counterparts enrolled in nonremedialcoursework. Findings include that students enrolled innonremedial mathematics courses enter the institution with many advantages over students enrolled inremedial mathematics. Tests of a path analytic modelconfirmed that background variables play a major role indetermining success in college mathematics.     

Innovations in Doctoral Education: Distance Education Methodology Applied

This study evaluated the impact of a distance education program to meet the practice learning needs of first‐year doctoral students. The program, a six‐session case‐based telephonic seminar, was taught to 19 first‐year doctoral students. Evaluation of the program included self‐report quantitative and qualitative data gathered pre‐ and postseminar, as well as qualitative data gathered three months postseminar. Quantitative and qualitative analysis revealed increased reports of practice competencies by the conclusion of the seminar. Analysis also illustrated the importance of continued evaluation given the small sample size and pilot nature of this unique distance education program.     

Taking Shape: Supporting Preschoolers' Acquisition of Geometric Knowledge Through Guided Play

Shape knowledge, a key aspect of school readiness, is part of early mathematical learning. Variations in how children are exposed to shapes may affect the pace of their learning and the nature of their shape knowledge. Building on evidence suggesting that child‐centered, playful learning programs facilitate learning more than other methods, 4‐ to 5‐year‐old children (N = 70) were taught the properties of four geometric shapes using guided play, free play, or didactic instruction. Results revealed that children taught shapes in the guided play condition showed improved shape knowledge compared to the other groups, an effect that was still evident after 1 week. Findings suggest that scaffolding techniques that heighten engagement, direct exploration, and facilitate “sense‐making,” such as guided play, undergird shape learning.     

Guava extract （Psidium guajava） alters the labelling of blood constituents with technetium-99m

Psidium guajava （guava） leaf is a phytotherapic used in folk medicine to treat gastrointestinal and respiratory disturbances and is used as anti-inflammatory medicine. In nuclear medicine, blood constituents （BC） are labelled with technetium-99m （^99mTc） and used to image procedures. However, data have demonstrated that synthetic or natural drugs could modify the labelling of BC with ^99mTC. The aim of this work was to evaluate the effects of aqueous extract of guava leaves on the labelling of BC with ^99mTc. Blood samples of Wistar rats were incubated with different concentrations of guava extract and labelled with ^99mTc after the percentage of incorporated radioactivity （%ATI） in BC was determined. The results suggest that aqueous guava extract could present antioxidant action and/or alters the membrane structures involved in ion transport into cells, thus decreasing the radiolabelling of BC with ^99mTc. The data showed significant （P〈0.05） alteration of ATI in BC from blood incubated with guava extract.     

Intelligence assessment: Gardner multiple intelligence theory as an alternative

In the multiple intelligence framework, newer and more contextualized cognitive tasks are suggested as alternative to more traditional psychometric tests. The purpose of this article is to examine whether or not these two types of instruments converge into a general factor of cognitive performance. Thus, the Battery of General and Differential Aptitudes (BADyG: reasoning, memory, verbal aptitude, numerical aptitude and spatial aptitude) and a set of Gardner's multiple intelligence assessment tasks (linguistic, logical, visual/spatial, bodily-kinesthetic, naturalistic and musical intelligences) were administered to 294 children aged 5 to 7. The confirmatory factor analysis points out the absence of a common general factor considering both batteries, indicating instead the existence of two general factors, which gather the tests that encompass them. Also, these two general factors correspond to traditional and multiple intelligence assessments and show a statistically moderate correlation between them. These results challenge Gardner's original position on refusing a general factor of intelligence, especially when considering the cognitive dimensions measured which do not coincide with the more traditional tests of intelligence.     

Winners and Losers' in the Development of Home-School Literacy Partnerships: An Analysis of Discourses of Power

In the past decade, family literacy has been the focus of considerable research. This work has suggested multiple understandings of involvement, and that many schools tend to work within a definition of parent involvement that does little more than seek to conform parents and their children to the literacy practices of schools. This paper reports research that has considered how parents take strategic action on their own and their children's behalf to increase their educational opportunities. It looks closely at the ways relationships between families and schools are constructed, and presents two ‘telling cases’ of families' responses to school literacy practices assigned for work at home. In doing so, it attempts to bring voices from Australia to the dialogue on ways of viewing parental involvement. It does this from a community centred perspective with the focus on the process of constructing shared meanings and understandings. The research examines the specific literacy practices that are honoured and dishonoured in the name of ‘parent involvement’. In doing so, the paper attempts to make visible the potential ‘winners’ and ‘losers’ in the development of home-school literacy partnerships.
