The practice of dissection teaches students not only the foundations of anatomical knowledge but also encourages the development of professional competencies. Yet, the dissection of cadavers in the gross anatomy course can be a stress factor for medical students. There are a minor proportion of students who demonstrate strong emotional reactions in anticipation of being confronted with a cadaver. Therefore, in 2008, the authors implemented a voluntary course entitled, “Anatomical demonstrations of organ systems” (AD‐OS) in advance of the dissection course to ease this psychological burden. The question of whether attendees of AD‐OS showed less mental distress at the start of the dissection course compared with those that had not or only infrequently visited AD‐OS was addressed. AD‐OS attendees assessed their expected mental distress using a five‐point Likert scale before starting the dissection course and a second time at the end of their first day, after they had been confronted with a cadaver. AD‐OS was evaluated as excellent and the majority of students participated actively during teaching sessions. Overall, female students showed higher levels of mental distress. AD‐OS attendees assessed themselves as being less burdened by mental distress than members of the control group. Longitudinal analysis revealed that students who visited AD‐OS showed a marked decrease of their mental distress level, comparing prospective and retrospective ratings. This was significantly (P < 0.001; Z = ?6.061) different from nonattendees or those who visited AD‐OS only infrequently. AD‐OS satisfied its intended teaching goals and proved that a step‐by‐step introduction of dissection through anatomical demonstrations helped to reduce the mental distress of students. Future studies are planned to measure mental distress with objective instruments. Anat Sci Educ © 2012 American Association of Anatomists. 相似文献

A particular difficulty in physics learning is the fact that pupils’ “intuitive” concepts are often resistant to instruction. This article reports empirical results from two related studies within an interdisciplinary project of physics education and educational psychology in ray optics. Two different kinds of treatment groups (TG A and TG B), both targeted at widespread pupils’ intuitive concepts (N?=?511), were compared with the results of a control group (CG C) learning with conventional tasks (N?=?218) provided by a related study II. Pupils in TG A) of study I worked on cognitively activating tasks related to widespread intuitive concepts in ray optics explicitly requiring them to deal with multiple representations. Pupils in the TG B) of study I worked on the same intuitive concepts, but without the cognitively activating representational component. TG A) and B) were compared with each other and with CG C) learning with conventional tasks. The results indicated that tasks addressing widespread intuitive pupils’ concepts improved conceptual understanding significantly more than conventional tasks. There was evidence of a significant intermediate effect showing medium-term stability. 相似文献

Labor market conditions, a pervasive public discourse about the benefits of higher education, and parental hopes push many young working‐class people into university. The institutional culture and demands of university, however, often remain elusive and fraught with uncertainty. In this paper, I draw on qualitative interviews with first‐generation, working‐class students at a Canadian university to analyze the ways in which these students discuss their reasons to attend and their expectations for university, and the implications of their attitudes for their future success at university. Analysis of the interview data shows how the relatively high and risky investment of working‐class youth in education leads to strong utilitarian and vocational orientations toward university. Although a narrow focus on the career potential of university is generally perceived as problematic, I argue that it may also help working‐class students in their transition to university. Nonetheless, a critical educational process is necessary that not only helps working‐class students achieve their educational and occupational goals, but also understand their unique status in a social institution that they entered as outsiders. 相似文献

Learning can be seen as a task-oriented process which often requires the reorganization of existing knowledge, usually referred to as conceptual change. This paper describes a theoretical framework for the analysis of conceptual change that considers conceptual knowledge as a generative cognitive tool for the creation of more specific mental representations — propositional symbolic structures and analog mental models. According to this view, conceptual change is based on a task-oriented interaction between these different kinds of mental representations. The assumption is made that it is possible to foster conceptual change by presenting to students well-defined tasks that stimulate the construction of elaborated mental models as well as an intensive interaction between these models and the corresponding propositional representations. In order to test this assumption an empirical study was conducted, in which subjects had to express their prior knowledge about a complex subject matter from the field of geography (time differences on the earth), which contained various conceptual deficits. The subjects were then randomly assigned to different groups who received the same learning material but had to solve different learning tasks requiring differently structured mental models. Afterwards, the subjects were asked to express their knowledge about the subject matter again and were tested for understanding with a comprehension test. The results support the view that a task-oriented interaction between propositional structures and mental models can help learners to evaluate the consistency of their conceptual knowledge. Accordingly, conceptual deficits result in the formation of mental models with an inadequate structure. Such deficits can be detected if the respective model is used in a sufficiently variable way, whereas they can remain unnoticed if it is used in a limited manner. 相似文献

Visuo-spatial text adjuncts such as static or animated pictures, geographic maps, thematic maps, graphs, and knowledge maps that have been analyzed in the articles contained in this special issue provide complex pictorial information that complements the verbal information of texts. These spatial text adjuncts are considered as depictive representations that can support communication, thinking, and learning. An essential precondition of this supportive function is that the visuo-spatial displays interact appropriately with human visual perception and the individual's cognitive system, which is characterized by prior knowledge, cognitive abilities, and learning skills. Accordingly, effective learning with visuo-spatial text adjuncts can be fostered by instructional design and by adequate processing strategies, both dependent on sufficient understanding of how the human cognitive system interacts with these displays. Perspectives for further research in this area are provided. 相似文献
