知识建构共同体及其支撑环境

面对知识社会的挑战,我们需要将学校改造成为知识建构共同体。知识建构共同体是以思想的形成和持续改进为关注点的团体,其成员通过建构性的互动过程发展对于共同体有价值的思想。为了支持和促进知识建构共同体,本课题组研制了CSILE/知识论坛系统。本文对上述理论观点、技术系统以及有关的实验研究结果做了简要介绍。     

Multiple perceptions of children's aggression: Differences across neighborhood,age, gender,and perceiver

We investigated how overtly aggressive behavior was differentially perceived by two types of perceivers, teachers and peers, as a function of student neighborhood, gender, and grade level. Participants (N= 765) were predominantly African American students in grades 3‐5 recruited from two urban public schools in southern California. The neighborhoods surrounding the two schools differed in levels of identified violent crime and economic levels. Teachers in the community experiencing more violence perceived student behavior to be relatively less aggressive and more similar across genders than did teachers in the less violent community. Peers in the community experiencing more violent crime perceived both boys and girls to be somewhat aggressive, whereas in the less violent community, boys were perceived as aggressive more so than were girls. In general, agreement between teacher and peer perceptions was stronger for boys than for girls. © 2001 John Wiley & Sons, Inc.     

Self-regulated Science Learning with Highly Gifted Students: The role of cognitive,motivational, epistemological,and environmental variables

This research examines the issue of self-regulated learning among highly gifted elementary ( n = 93) and high school students ( n = 40) in science. Self-report measures assessed self-regulatory strategy use in science and a spectrum of environmental (perceived level of investigation) and individual prerequisites (motivational beliefs, goal orientation, epistemological beliefs and intentions). Firstly, high school students were experiencing less investigation in science, and test anxiety and work avoidance were more pronounced than with elementary students. Secondly, highly gifted girls' science-related motivational beliefs were less positive than those of boys. Thirdly, path analyses indicate that the level of investigation in the science learning environment strongly determines motivational and epistemological prerequisites of self-regulatory strategy use. The results indicate that exploration and discovery should be enabled and strengthened in science classrooms of highly gifted students.     

Design Principles for Distributed Knowledge Building Processes

In this paper we explore various interpretations of the term distributed cognition, then turn our attention to communities grounded in the practice of collaborative knowledge building. We discuss CSILE (Computer-Supported Intentional Learning Environments), a technology designed to support contributions to a communal database. Shared responsibility for this community resource extends to aspects of school practice typically handled exclusively by teachers, and engagement in improving and connecting the contents of the database makes the process of knowledge building self-sustaining. We discuss knowledge building communities involving students and teachers, and end with discussion of design principles for distributed knowledge building processes.     

The Independence of Research—A Review of Disciplinary Perspectives and Outline of Interdisciplinary Prospects

Intelligence,Creative Thinking,and Sociometric Choice Among Fifth-Grade Children

In a sample of 970 female and 968 male freshmen taken over a 5-year period at the College of Wooster it was found that the Math and Verbal Scholastic Aptitude Tests (SAT) were more highly correlated with freshman grade point average (GPA) than were any of the eighteen scales of the California Psychological Inventory (CPI). Stepwise regression led the author to suggest a series of five variables for each sex which might be used to predict academic achievement using the SAT and the CPI. For women, a multiple R of .52 was reached using Math, Verbal, Socialization, Achievement via Conformity, and Flexibility. For men, Math, Verbal, Socialization, Flexibility, and Femininity provided a multiple R of . 57.     

Adapting the Scoring Matrix: A case study of adapting disciplinary tools for learning centred evaluation

The scoring matrix, a method used to facilitate community participation in collaboratively planning and monitoring development projects in natural resource management, was adapted to promote collaboration and reflection in a course in participatory resource management. The scoring matrix is described and its strengths and weaknesses in relation to key objectives are analysed. The matrix represents an innovative approach to evaluation that may be useful in a variety of fields. The authors argue, too, that the case is an example of how discipline (and profession-) specific tools can be adapted in an educational setting to serve the dual purposes of promoting experiential learning of particular key skills, and of monitoring and evaluating student learning. They suggest that academics in other fields may wish to consider participatory tools like the scoring matrix or adapt the tools of their own disciplines as ways of collaboratively evaluating teaching in their own disciplines/professions.     

The interaction of student and program variables for the purpose of developing a model for predicting graduation from graduate programs over a 10-year period

The purpose of this study was to investigate whether there is some factor or set of factors which will predict the probability of graduation from doctoral programs. This study concentrated on two areas: (a) the factors available to the selection committee when the students apply for admission into graduate programs, and (b) those factors emerging after admission, resulting from the students' meeting program-imposed requirements for graduation. Data were collected from the file of each student admitted to the doctoral program in Educational Administration. The results of the study indicated that program variables are more important than admission variables in predicting graduation. and the technique of Path Analysis is highly recommended to study the problem of student progression through graduate departments.     

Required Collaborative Work in Online Courses: A Predictive Modeling Approach

This article describes a predictive model that assesses whether a student will have greater perceived learning in group assignments or in individual work. The model produces correct classifications 87.5% of the time. The research is notable in that it is the first in the education literature to adopt a predictive modeling methodology using data collected via a designed experiment. All subjects experienced both a collaborative and an individual assignment, thus mitigating uncontrolled external factors in the measurement of differences in perceived learning. The exploratory nature of the work prompted the use of Partial Least Squares Regression for estimation. The work serves as an illustration of how predictive modeling might enlighten those in educational and academic settings.
