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 Relations Between Early Working Memory Abilities and Later Developing Reading Skills: A Longitudinal Study From Kindergarten to Fifth Grade 下载免费PDF全文
This study investigated the relations of early working‐memory abilities (phonological and visual‐spatial short‐term memory [STM] and complex memory and episodic buffer memory) and later developing reading skills. Sixty Hebrew‐speaking children were followed from kindergarten through Grade 5. Working memory was tested in kindergarten and reading in Grades 1, 2, and 5. All memory measures, but phonological STM, correlated with reading up to Grade 5. Regression analyses (with intelligence quotient controlled) demonstrated that phonological complex memory predicted all reading skills in Grade 1, and accuracy in Grade 2. The rather understudied visual‐spatial memory predicted comprehension in Grades 2 (STM) and 5 (complex memory). The results point to an important role of the phonological complex memory in early assessment, and suggest a long‐lasting role of early visual‐spatial memory in predicting variance in reading. Whether this role of the visual‐spatial memory is unique to the Hebrew orthography because of its visual features requires, however, further investigation. 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

The emergent perspective (Yackel and Cobb, 1996) is a powerful theory for describing cognitive development within classrooms.
Yackel and Cobb have shown that the formation of social and sociomathematical norms, and opportunities for learning are intertwined.
The present study is an attempt to extend the range of application of the emergent perspective to middle high school classrooms.
The learning environments we consider are rich in the sense that (i) the tasks in which students are engaged are open-ended
problem-situations (ii) the activities around the tasks are multiphased, consisting of small group collaboration on problem
solving, reporting and reflection in a classroom forum with the teacher (iii) the tools used are multi-representational software.
We identify here some practices rooted in such rich environments from which several sociomathematical norms stemmed. The present
study shows that socio-mathematical norms do not rise from verbal interactions only, but also from computer manipulations
as communicative non-verbal actions.
