Breaking the tyranny of office hours: Overcoming professor avoidance

ABSTRACT

Studies have found that Faculty–Student Interaction (FSI) has many positive benefits for students including academic support, professional development, mentoring, and career planning. Research-intensive universities exhibit the lowest levels of faculty–student interaction within higher education. This article utilises qualitative methods to explore faculty, student, and staff perceptions of faculty–student interactions, particularly those that take place out of the classroom, at a research-intensive public U.S. university. We identify social distance between faculty and students based on unequal status within a rigid, hierarchically-organised culture as a key barrier to FSI. We then discuss methods that some of the faculty in our study used to mitigate their social distance with students in an effort to increase FSI.     

Picking the winners by consensus: Grant-giving practice in the Netherlands

The Netherlands form a consensus democracy. In such a society the legitimacy of decisions is of great concern to all. An elaborate system of checks and balances tends to exist and the pressure to join an emerging consensus at meetings is both subtle and tremendously powerful. In the Dutch system of higher education and research the manifestations of the consensus ideal are numerous. This paper highlights them where appropriate. It reviews the Dutch research effort in an international perspective and concludes that R&D expenditure in the Netherlands, measured as a proportion of GDP, is declining. Fairly radical changes in science policy orientation since the 1960s are reviewed and the current frameworks for policy formulation, academic foresight and the organisation of support are sketched. After discussing NWO's different funding instruments, the practices of picking the winners are described in some detail. Three different peer review models are then discussed with special attention to their strengths and weaknesses. The paper's final section is focussed on the evaluation practices in force.     

The nexus between college choice and persistence

Initial student commitments have long been considered an influence on persistence, but the reasons why students choose to attend a college have seldom been considered as dimensions of initial commitments that could influence persistence processes and outcomes. This study used NPSAS-87 to examine the influence of finance-related reasons for choosing a college on persistence decisions. The findings include (1) finance-related choices have direct and indirect influences on whether students persist in college; and (2) market-based, monetary measures of financial aid, tuition costs, housing costs, and other living costs have a substantial direct effect on persistence.     

Towards powerful learning environments for the acquisition of problem-solving skills

It is generally agreed that acquiring thinking and problem-solving skills is nowadays a primary objective of general education. Responding appropriately to this challenge requires an answer to the following questions: 1. what does the acquisition of problem-solving skills involve, and 2. how can those abilities be fostered through systematic instruction? This contribution describes a four-step model of skilled problem-solving processes, and gives an overview of three major categories of cognitive skills involved in competent problem solving, namely, the flexible and integrated application of domain-specific knowledge, of heuristic methods, and of metacognitive skills. Furthermore, a framework is presented for the design and elaboration of powerful teaching-learning environments in which such problem-solving skills can be acquired efficiently. Two basic ideas underlying this model are: the view of learning as a constructive process, and the idea of cognitive apprenticeship as an effective and appropriate method for learning and teaching. Finally, some recent research findings supporting the educational significance of the framework are briefly reviewed.     

What really influences minority attendance? Sequential analyses of the high school and beyond sophomore cohort

While the factors that influence college minority student attendance have been the subject of recent study, there remain unresolved questions about how different factors influence college attendance decisions of applicants from historically disadvantaged backgrounds. In particular, there is ambiguity about whether blacks are more or less likely to attend than whites and what factors might improve their attendance rates. This study uses two sets of logistic regressions to identify the factors that can promote minority attendance: a set that examines attendance by all high school seniors in the high school class of 1982 and a set that examines attendance by college applicants in this class. Consistent with prior research on student access, three factors are identified that can potentially improve college attendance by minority students: (1) improved academic preparation in elementary and high school; (2) increased aspirations for higher levels of educational attainment; (3) increased levels of financial aid. Public interventions that would improve any of these factors for minority high school students are likely to improve minority participation rates.
