Regression Models with Errors in the Predictor Variable

In this article Simon Day describes a computer simulation exploring one of the fundamental assumptions of regression analysis which causes students difficulties.

The perceived value of work placements and part-time work and its diminution with time

This paper explores the perceptions of degree students at two UK universities regarding their work placement and part-time working activities, to assess if the two activities converge. The research comprises three stages: interviews for preliminary exploration of students’ perceptions towards work placement and part-time work; interviews to examine how placement opportunities link with career aspirations; a survey of students who had completed a placement, and those currently on placement. Students acknowledged part-time working helped their placement activity, providing transferable skills beneficial to both study and career aspirations. A significant finding was with respect to time: the closer to the placement activity the data was collected, the stronger the impact of appreciating the value of placement. The paper therefore highlights the value of timing in the assessment of work placement. It also offers value for universities’ by providing insight into students’ perceptions regarding embedded external work activities that can enhance graduate employability and career prospects.     

Measuring the quality of e‐learning

This paper shows how concept mapping can be used to measure the quality of e‐learning. Six volunteers (all of them 3rd‐year medical students) took part in a programme of e‐learning designed to teach the principles of magnetic resonance imaging (MRI). Their understanding of MRI was measured before and after the course by the use of concept mapping. The quality of change in individuals' maps was assessed using criteria developed to distinguish between meaningful and rote‐learning outcomes. Student maps were also scored for evidence of conceptual richness and understanding. Finally, each map was compared directly with the content of the electronic teaching material. The results show that many of the student misconceptions were put right in the course of their learning but that many of the key concepts introduced in the teaching were ignored (or sometimes learnt by rote) by the students. This was because the teaching material locked these new ideas in structures and terminology that precluded meaning‐making among non‐experts. Our data suggest that students' prior knowledge is a key determinant of meaningful learning. We suggest that this must be acknowledged if the design and use of electronic teaching material is also to be meaningful. Ultimately, measures of student learning are the only authentic indicators of the quality of teaching through technology.     

Romantic Partner Selection and Socialization During Early Adolescence

This prospective study examined romantic partner selection and socialization among a sample of 78 young adolescents (6th–8th graders). Independent assessments of adolescent and romantic partner adjustment were collected before and after relationships initiated via peer nomination and self‐report. Prior to their relationship, adolescents and partners were significantly alike on popularity, physical attraction, and depressive symptoms. Controlling for initial similarity, partners’ popularity, depressive symptoms, relational aggression, and relational victimization significantly predicted changes in adolescents’ functioning in these areas over time. However, the magnitude and direction of change varied according to adolescents’ and partners’ prerelationship functioning. In general, adolescents who dated high‐functioning partners changed more than those who dated low‐functioning partners, and partner characteristics predicted greater change among low‐ versus high‐functioning adolescents. Results were consistent even when controlling for best friend characteristics. The current findings are among the first to demonstrate unique contributions of romantic partner characteristics to adolescents’ psychosocial functioning.

Developing academics’ assessment practices in open,distance and e-learning: an institutional change agenda

Abstract

Universities across the globe are attempting to change assessment practice to address challenges in student engagement and achievement. Integral to this objective are strategies to develop academics’ assessment practice. These frequently focus on attendance at formal Continuous Professional Development events and/or implementation of institutional blueprints. This editorial article uses a case study from the Open University (UK) to explore an alternative ‘communities of practice’ approach to the improvement of assessment arguing that academics’ professional expertise is best deepened through participation in authentic activities of teaching and scholarship. The discussion identifies what is involved in such an approach including the role of an enabling principles-based framework, the constraints on implementation and the implications for HE leaders.     

Higher education policies in Brazil: 1970–90

Under the authoritarian regime, policies on higher education were mostly produced by the Excutive. First of all, an Educational Reform made up for the rapid expansion of a huge private sector where small teaching institutions prevail and which now absorbs over 60% of Brazilian students. The public sector, in turn, was substantially improved: the number of full time faculty increased and teachers in the federal universities were encouraged to apply for a M.A. or a Ph.D. and to get involved with research activities. Meanwhile, a dual funding system (teaching and research) emerged which was responsible both for the creation of graduate programmes all over the country and for the expansion of a research infrastructure. The civilian government (1985 on) brought policy making out of the bureaucracy and into the Congress. The new Constitution granted the university a degree of autonomy it had never enjoyed before which, however, is still to be regulated by further legislation. Policy initiatives driving at institutional differentiation and at performance assessment have systematically failed to become effective due to resistances within the university itself. Meanwhile financial stringency at a time of recession necessarily leads to reductions in funding, notably for research.
