Motivation to commit oneself as a determinant of achievement in problem-based learning

Problem-based learning is a constructivist approach toprofessional education stressing the use of real lifeproblems in education. Several previous attempts tounderstand the intricacies of learning in theproblem-based context have led to a causal model,elements of which were tested in the present study.The focus of the investigation was on the students' motivation to committhemselves to studying in a problem-based healthsciences curriculum, expressed in term of levels ofattendance at tutorial meetings. Data were collectedregarding functioning of the tutorial group, tutorfunctioning, level of prior knowledge, quality of theinstructional problems, time spent on individualstudy, academic achievement and increased interest.These data were analyzed using a structural equationsmodeling approach. As hypothesized, commitment appears to bea potent determinant of achievement. In fact, itrepresents one of the strongest determinants oflearning in the model tested.     

How to assess for improvement of learning

This review summarizes and builds on a seminar about assessment of student learning in higher education. Assessment can be looked upon as simply something that has to be done at the end of a course. During the course of discussions at the seminar the participants became more aware of how assessment can have an impact on learning. This means that assessment can be used as a means to improve learning. This realization is not a new one, but it is highlighted here in a more coherent and concise way than usual. Many alternative methods of assessment are possible. Some instructional design rules will be presented here for designing assessment sessions in such a way that learning can be improved. When designing an assessment method, one can be guided by the following considerations. The content of assessment should be chosen in accordance with the learning outcomes one hopes to achieve. The organization of assessment can be designed in such a way that the desired learning process is promoted. The outcome of assessment can provide feedback to many of the stakeholders: to the students on their learning process; to the faculty on its outcomes; and to the teacher by pointing out the following steps to be taken in improving assessment, learning and teaching.

Learning more by being taught less: a “time-for-self-study” theory explaining curricular effects on graduation rate and study duration

In this article, an alternative for Tinto’s integration theory of student persistence is proposed and tested. In the proposed theory, time available for individual study is considered a major determinant of both study duration and graduation rate of students in a particular curriculum. In this view, other activities in the curriculum, in particular lectures, constrain self-study time and therefore must have a negative impact on persistence. To test this theory, we collected study duration and graduation rate information of all—almost 14,000 students—enrolling in eight Dutch medical schools between 1989 and 1998. In addition, information was gathered regarding the timetables of each of these curricula in the particular period: lectures hours, hours spent in small-group tutorials, practicals, and time available for self-study. Structural equation modeling was used to study relations among these variables. In line with our predictions, time available for self-study was the only determinant of graduation rate and study duration. Lectures were negatively related to self-study time, negatively related to graduation rate, and positively related to study duration. The results suggest that extensive lecturing may be detrimental in higher education. However, in the curricula employing limited lecturing considerable energy was spent in supporting self-study activities of students and preventing postponement of learning. Given our findings, both activities will likely have large pay offs, in particular in curricula with low graduation rates.     

Accuracy of students' self‐assessment and their beliefs about its utility

The purpose of the two studies presented here was to evaluate the accuracy of students' self‐assessment ability, to examine whether this ability improves over time and to investigate whether self‐assessment is more accurate if students believe that it contributes to improving learning. To that end, the accuracy of the self‐assessments of 3588 first‐year students enrolled in a post‐secondary institution was studied throughout a semester during which each student made approximately 80 self‐assessments about his or her own learning process. These self‐assessments were then compared with multiple judgements by peers and tutors. The overall correlations between the scores of self‐, peer and tutor assessments suggest weak to moderate accuracy of student self‐assessment ability. The findings also reveal an ability effect; students judged as more academically competent were able to self‐assess with higher accuracy than their less competent peers. Comparing the accuracy of student self‐assessment averaged over four consecutive periods indicates that the accuracy does not improve over time. In a second study, a questionnaire aimed at eliciting student's beliefs about the effects of self‐assessment on their learning was administered to 936 first‐year students. Based on their responses, sub‐groups of students were identified: those who either believed in the usefulness of self‐assessment or did not. Results suggest that there is no significant association between student beliefs about the utility of self‐assessment and the accuracy of their self‐assessments.     

Library Catalog Analysis as a tool in studies of social sciences and humanities: An exploratory study of published book titles in Economics

This paper explores the use of Library Catalog Analysis (LCA), defined as the application of bibliometric or informetric techniques to a set of library online catalogs, to describe quantitatively a scientific-scholarly field on the basis of published book titles. It focuses on its value as a tool in studies of Social Sciences and Humanities, especially its cognitive structures, main book publishers and the research performance of its actors. The paper proposes an analogy model between traditional citation analysis of journal articles and Library Catalog Analysis of book titles. It presents the outcomes of an exploratory study of book titles in Economics included in 42 academic library catalogs from 7 countries. It describes the process of data collection and cleaning, and applies a series of indicators and thematic mapping techniques. It illustrates how LCA can be fruitfully used to assess book production and research performance at the level of an individual researcher, a research department, an entire country and a book publisher. It discusses a number of issues that should be addressed in follow-up studies and concludes that LCA of published book titles can be developed into a powerful and useful tool in studies of Social Sciences and Humanities.
