Combined online and in‐class pretesting improves exam performance in general psychology

This study examined the effect of distributed questioning on learning and retention in a college lecture course. A total of 48 question pairs were presented over four exams. The 16 question pairs associated with each of the three blocks of the course appeared on the block exams, and all 48 appeared on the final exam. The two questions in each pair were related to each other, so that knowing the answer to one question usually implied knowing the answer to the other. One question in each pair was included in an experimental condition, in which questions were presented online, in class, or both online and in class, before appearing in exams. These conditions were counter‐balanced across the sample. The control questions appeared only in exams. Providing a question online in advance of class, as well as in class, had a significant long‐term effect on the probability of knowing the answers to both experimental and control questions when they appeared in exams. These results demonstrate that coordinated online and in‐class instruction can significantly improve exam performance. These results are consistent with the hypothesis that distributed instruction creates more robust memory traces, rather than the hypothesis that it creates additional memory traces.     

Effects of component training and subsequent sequencing of stimuli on shuttlebox avoidance responding of rats

The serial presentation of two different CSs, with each stimulus having an 8-sec duration (S1₈/S2₈), consistently has resulted in most of the shuttlebox avoidance responses being recorded to the S2 component. Experiment 1 attempted to attenuate this serial CS, delayed-response effect by conditioning the separate components of a serial CS prior to ordering them sequentially. Ten component-training trials were administered, with subjects receiving CS-US pairing to S1 only, S2 only, or to both S1 and S2 presented on separate trials. Two CS durations (8 or 16 sec) during this phase also were compared. Subjects were then given 100 avoidance test trials using the standard serial procedure. The 10 best avoidance responders in each group were selected for analysis. Shorter avoidance latencies were obtained only for subjects receiving component conditioning to S1. CS duration was not a factor in establishing the shorter latencies. Component conditioning to S2 resulted in increasing the total avoidances. Experiment 2 increased the number of component-training trials and the generality of the findings by using a different strain of rats and by extending the testing phase of the study so that all subjects could be included in the analysis. Comparable results were obtained. The theoretical implications of these data were discussed.     

Opportunities to Learn and Achievement in Mathematics in a Sample of Sixth Grade Students in Lima, Peru

In recent years, the mathematics achievement of Peruvian students has been evaluated in three national and two international studies. The results in all cases suggest very poor learning. A similar situation is found in many developing countries. In this study, we analyzed the opportunities to learn (OTL) mathematics of sixth grade students from 22 public schools in Lima, Peru. OTL were defined in this study as curriculum coverage, cognitive demand of the tasks posed to the students, percent of mathematical exercises that were correct and quality of feedback. These variables were coded in the workbooks and notebooks of the students, which were gathered at the end of the school year (at the same time, the mathematics achievement test was administered). The results show that: (a) regarding OTL, less than half of the exercises available in the workbooks were solved, teachers overemphasize some topics of the national curriculum ({i.e.} related to Number and Number Sense), they pose tasks that are at very low levels of cognitive demand, and it is common to find mistakes in the students' answers to problems that have no feedback (or even worse, the feedback is wrong); (b) students in relatively poorer, multigrade classrooms have less OTL; (c) OTL, as defined earlier, is positively associated with achievement.A preliminary version of this paper received the Research Medal in the category Knowledge, Education andTechnology at the Annual Meeting of the Global Development Network (GDN) in Cairo, in January 2003.     

Beyond internationalisation and isomorphism – the construction of a global higher education regime

ABSTRACT

National higher education systems are undergoing profound changes, discussed in many but unrelated studies as outcomes of internationalisation dynamics and institutional isomorphism pressures. We propose to link these studies by emphasising the influence of both internationalisation and isomorphism on the formation of a global educational regime. Through a broad range of indicators, we describe the growth of the discursive, normative, and regulatory dimensions of such a global higher education regime. We find evidence of the following developments: (1) a rapidly growing network of international organisations focused on conferences, initiatives, and programmes supporting a global higher education agenda; (2) a striking increase in the number of international and national accreditation agencies, their mutual cross-national recognition as well as the number of universities that are nationally and internationally accredited; and lastly, (3) parallel increases in regional qualification frameworks and in the implementation of national qualification frameworks. These developments create integration pressures manifest in the mutual recognition of higher education degrees, for which a new generation of regional conventions has emerged worldwide in the past two decades. We discuss these processes and their implications for understanding ‘national’ higher education as well as the threats and limits to the burgeoning higher education regime.
