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

A combined criterion involving the regression slopes of pretest-posttest achievement scores and achievement gain scores was used to classify similar types of classrooms. Mathematics achievement differences among 632 fifth graders were analysed in a longitudinal design and explained in a structural equation framework provided by LISREL, separately for four types of classrooms. The results replicated the findings of an earlier study (Schneider & Treiber, 1984) in that the local nature of achievement models could be demonstrated. That is, the structural components of the causal models could not be generalized across the four groups of classrooms. The inclusion of a second grouping criterion (i. e., achievement gain) proved useful in that a better model fit was always obtained for classrooms with high achievement agains. As a global model test ignoring group and classroom membership did mask the differential validity of the achievement model in the various subgroups, the need for multilevel approaches was emphasized. 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

New technologies allow the display of text, static visuals, and animations. Although animations are inherently attractive,
they are not always beneficial for learning. Problems may arise especially when animations modify the learner's cognitive
load in an unintended way. In two learning experiments with 40 and 26 university students, the effects of animated pictures
on knowledge acquisition were investigated. Some pictures displayed visual simulations of changes over time, whereas other
pictures could be manipulated by learners to represent different states in time. Results showed that manipulation pictures
had an enabling function for individuals with high learning prerequisites, whereas simulation pictures had a facilitating
function for individuals with low learning prerequisites. However, the facilitating function was not beneficial for learning,
because learners were prevented from performing relevant cognitive processes on their own. A careful analysis of the interrelation
between different kinds of cognitive load and the process of learning is therefore required. 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

The conditions for growing up in the context of formation and education, socialization and formal, non-formal, and informal learning have distinctively changed since 2000 due to digital and convergent mediality. Parallel to the expansion of all analog and digital media, and the permanent and ubiquitary presence of data, information, pictures, sounds, and texts, the aesthetical and cultural-artistic receives a new and enhanced relevance: Participatory Web 2.0 communication, new social networks, and individual approaches to media scope for design are always based on perception. One could speak of an “aesthetical imperative” of all media communication, receptive and productive. Cultural-aesthetic media education connects and focalizes these dimensions ranging from real lived-in worlds to virtual media worlds to a unity, which also includes senses and arts, in a balancing interplay. In the light of aesthetical learning in the information age of a network society, performation, transformation, participation, and interaction become educationally relevant pragmatic orientations to the benefit of an art of living 2.0. With this, a new and particular challenge arises, corresponding with the complementary and revalidating need of bodily-spatial aesthetic and, pointed, arts and culture pedagogical goal orientation and pedagogically produced offers of experience and action. 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
