Science is increasingly a team activity, and the size of the teams has been growing. At the same time, there are concerns about an increasing rate of pathologies in science. The growth of team science suggests the need to look beyond individual-level explanations and focus on organizational structures and institutional contexts to explain pathologies in science. Drawing on the literature on organizational pathologies, we argue that division of labor may be a key factor contributing to pathologies in science. Furthermore, we examine the effects of high-stakes incentives and of institutional corruption as additional predictors of scientific pathologies. Using retractions as an indicator of pathologies, and drawing on a matched sample of 195 retracted papers and 349 paired papers that were not retracted, we develop indicators of the division of labor in the team that produced a paper and find that the rate of retractions is higher as the division of labor increases (net of team size). Additionally, we find that high-stakes incentives and institutional corruption are also associated with increased retractions. We conclude with a discussion of the implications of these findings for science policy, in particular for organizing team science projects. 相似文献

We are witnessing a mad rush to pour educational content into games in an ad hoc manner in hopes that player/learners are motivated simply because the content is housed inside a game. A failure to base educational game design on well-established learning and instructional theories increases the risk of the game failing to meet its intended educational goals, and yielding students who are entertained but who have not acquired any academic skills or knowledge. Our review of standalone educational games has shown that they are not always based on sound educational principles and theories. We contend that, if academic learning is to take place, a new design paradigm must be developed. This article discusses the RETAIN design and evaluation model for educational games that was developed to aide in the evaluation of how well academic content is endogenously immersed and embedded within the game’s fantasy and story context, promoters transfer of knowledge, and encourages repetitive usage to that content becomes available for use in an automatic way. 相似文献

A single science textbook often provides the syllabus for courses at upper secondary and tertiary levels, and may be used as a principal source of information or explanation. The research reported in this article challenges such practices. The ways in which the concept, acceleration, is treated in physics textbooks is compared with understandings of the concept demonstrated by final-year secondary (Year 12) and first-year university students. Some students' understandings are shown to be incomplete in ways that parallel misleading or inaccurate textbook treatments of the concept. In addition to misleading or inaccurate statements, the limitations of some textbook treatments of acceleration were found to include: lack of attempts to make explicit relationships with other concepts, failure to point out when it is appropriate to use particular definitions or that an alternative definition might be more appropriate in specific situations, inclusion of operational definitions without conceptual explanations, and a focus on quantitative treatments while overlooking the development of qualitative understanding. Two principal aspects that distinguished the ways in which the students understood acceleration were identified: (a) the relation between acceleration and velocity; and (b) the relation between acceleration and force(s). The results of the study have implications for teaching and, in particular, for the use of textbooks in teaching. These implications are discussed in the article. 相似文献

In each of two studies, teachers were randomly assigned to either a Virtual Workshop (VW) group that used a computerized professional development program or an Actual Workshop (AW) group that participated in face-to-face professional development, including discussion, feedback, and collaboration. In both studies, teachers’ posttest scores related to their knowledge of the Question Exploration Routine and their plans for using it were significantly higher than their pretest scores. In Study 2, both groups’ posttest scores with regard to implementation and planning of the routine were significantly greater than their pretest scores. There were no significant differences between the groups at posttesting on any measure. The posttest knowledge scores of the whole groups of students and the subgroups of students with LD being taught by both groups of teachers were significantly higher than their pretest scores. All teachers indicated that they were satisfied with the training and the routine. VW teachers in both studies indicated that they were satisfied with the software program. 相似文献

This study describes the development of an assessment to evaluate the well-being of PhD researchers using a clinically approved methodology that places the perceptions and experiences of the subject population at the heart of its construction. It identifies and assesses the range and relative importance of seven distinct dimensions which are shown to impact adversely on the perceived well-being of student researchers across all stages of their studies. According to the findings, the well-being of doctoral students comprises needs relating to development, facilities, home and health, research, social, supervisor and university. The instrument was found to demonstrate good content validity and internal reliability. Its use offers new insights into the experiences of early career researchers and may inform efforts to better support them. This, in turn, may have a positive impact upon retention levels and future career choices for this research population. 相似文献

Abstract The present experiment investigated the recall of terminal location and distance of both preselected and constrained short movements (12 cm ± 4 cm approximately) following 5 second and 30 second unfilled retention intervals. Systematic alteration of the magnitude and direction of the starting position for recall movements revealed that the distance moved markedly interfered with the recall of the terminal location, but distance was essentially recalled independently of terminal location. Recall of distance was superior to terminal location for both the unfilled retention intervals, and there was a decrease in location recall performances following the longer 30 second delay when compared to recall attempts after the shorter 5 second delay. The Findings are discussed in terms of recent proposals to account for the memory for, and control of, discrete limb movements. 相似文献
