English:This paper deals with decision-making aspects of the introduction of distance learning (DL) into university instruction and learning. Teacher/student interactions are examined and a model is suggested for the introduction of DL into the university teaching and learning arena whilst ensuring the realization of the potential of DL methodology both educationally and cost-effectively. Francais: Cet article traite des aspects des prises de décision dans l'introduction des systèmes d'enseignement à distance a l'université. Les interactions enseignements-enseignés sont examinées, et on suggère un modèle pour l'ntroduction de l'enseignement à distance dans l'université tout en mettant à profit le potentiel de la methodologie de l'enseignement à distance tant au point de vue éducation qu'au point de vue coût-efficacité. Deutsch:Dieses papier beschreibt aspekte der entscheidungsfindung für die einführung von DL für lehren und lernen an universitäten. Auf der basis von lehrer/schüler - interaktionen wird ein modell fur die einführung von DL im Universitätsbereich vorgeschlagen, das dessen möglichkeiten auf pädagogischem gebiet unter dem aspekt der kosteneffizienz sicherstellt. 相似文献

The study reported here is based on the results of two international studies: IEA's Second Information Technology in Education Study (SITES) Module 2, focusing on innovative pedagogical practices at the classroom level, and OECD/CERI Case Studies of ICT and Organizational Innovation, focusing on ICT related innovations at the school system level. In the paper we analyze the data collected in ten innovative schools in Israel which have incorporated ICT in unique ways and have succeeded in devising innovative classroom pedagogies and school system changes. The major research questions addressed are: (a) What levels of innovation were observed in the participant schools, and in which domains? (b) How does the level of innovation in the various domains vary among and within schools? (c) What correlation patterns among levels of innovation in the various domains can be identified? The results of ten comprehensive case studies of exemplary schools in Israel were analyzed by mean of the innovation analysis schema developed by us for characterizing ICT-based educational innovations. 相似文献

Studies of knowledge constructing often focus on the analysis of a single episode, without considering enough the history
of the learners, or the future learners' trajectories with regard to the concepts learned. This paper presents an example
of knowledge constructing within the context of peer learning. We show how the design of the task and the tools available
to the students afford the constructing of conceptual knowledge (the phenomenon of exponential growth and variation, as it
is expressed in its numerical and graphical representations). We trace the constructing of knowledge through a series of dyadic
sessions for a few months in a classroom environment. We show that knowledge is constructed cumulatively, each activity allowing
for the consolidating of previous constructs. This pattern indicates the nature of the processes involved: knowledge constructing
and consolidating are dialectical processes, developing over time, when new constructs stem from old ones already consolidated,
which gain consolidation through the new construction, creating a new abstract entity. We also discuss the potential of the
tool the students used (a spreadsheet program) to such processes of learning mathematics. 相似文献

The aim of this article is to increase understanding of the development of spatial practices in virtual learning environments. The spatial change and development in 38 small-group e-discussions taken from a data set of a yearlong 8th-grade humanities course are described and analyzed. We show that the focus on spatial changes in computer-supported collaborative learning (CSCL) environments enriches the scope of activities in virtual environments that are usually studied from the perspective of productivity and disciplinary knowledge building only. We argue that tracing spatial changes enables researchers to scrutinize the freedom to act and exercise power over others, something crucial for the development of political agency. We show that these developments are decisive for students to become competent citizens. Implications the study has for CSCL design and for political education are discussed. 相似文献

In spite of the hundreds of studies done on teacher evaluation by student ratings, there are still several major controversial issues of how to construct evaluation instruments that best serve their purpose. The present study contributes to one of the ongoing debates of recent years that addresses the number of teaching dimensions to be considered in decision making, namely, whether to use a single score or multiple scores for teacher evaluation. The study demonstrates using a short form on which the global score overall teaching performance can almost perfectly predict the mean of all teacher-attribute items. The questionnaire used in this study was administered eight times—twice a semester for two years—for all faculty members and TAs in the departments of physics and chemistry at Tel Aviv University. The composition of teacher attribute items was different for the faculty members and TAs, reflecting their different teaching functions—lectures versus recitation problem solving. Results show that while for the faculty the global score can simply replace the mean of all instructor-attribute items and serve as a single score that faithfully represents all dimensions of teacher ratings, for the TAs, a linear transformation is needed. 相似文献
