Describes a study that explores the instructional influence of presenting pictures at the molecular level when introducing chemistry concepts and solving chemistry problems. Explores the effect of the pictures on students' conceptions and problem-solving abilities. Contains 59 references. (DDR)

Lends support to the idea that the quality of the cases used in problem-based learning affects the nature of student learning in this context. Outlines seven principles adapted from research on learning and cognition that can help guide case design. Contains 22 references. (DDR)

Proposes that once the elements of procedural understanding have been explicitly defined, appropriate teaching strategies can then be used to enable student understanding. Argues that explicitly teaching these concepts may add rigor to GNVQ assignments. (DDR)

Discusses knowledge utilization processes, from general studies on utilization of research to a focus on those specific to educational settings. Factors that can facilitate the use of knowledge in school are examined. (50 references) (AEF)

Reports on the design of an automated query system to help pharmacologists access the Derwent Drug File (DDF). Topics include knowledge types; knowledge representation; role of the search intermediary; vocabulary selection, thesaurus, and user input in natural language; browsing; evaluation methods; and search statement generation for the World…

Computer-Supported Intentional Learning Environments (CSILE) is a database system in which learners collaboratively construct the knowledge represented in the database. This study examines how students in a grade-five and -six classroom built their database on a science topic, electricity. Differences in cognitive and operative activities between…

Conceptual learning of 13 graduate students was studied during a six-week course using the Internet for collaborative learning of online articles. Five groups were formed with each creating a knowledge map during the first and fifth week of the course. Multidimensional scaling analysis was used to study change in each group's mapping over time to…

Describes a project in which student teachers chose science exhibits and created webpages to communicate some aspect of the underlying science in the exhibit. Student teachers participating in the project developed personal understanding of some difficult areas in science. (DDR)

Speculates about reasons for the lack of use of concept mapping as an instructional strategy. Concludes that the two main barriers to its extensive adoption are the epistemological beliefs of classroom teachers and the underlying philosophy of the curriculum. (Contains 45 references.) (DDR)

The emergence of computer and network technologies has presented the archival profession with daunting challenges as well as inspiring opportunities. Archivists have been actively imagining and realizing the application of advanced technologies to their professional functions and activities. Using advanced technologies, archivists have been…

Constructing a data model for a problem area requires identifying and formulating some symbolic representation of the concepts involved, their characteristics, and the relationships between them. Taking a socio-cultural perspective on learning, analysis of classroom dialog is used to identify cognitive challenges met by novice students of data…

The design and development of GRACILE, a collaborative learning environment in the domain of Japanese language patterns and expressions, is described. The environment is designed to allow learning goals communication, learning activities negotiation, and collaboration between learners. From a group of student models, a potential development level…

This paper addresses dilemmas in the practices of six teachers from the perspective of alternate paradigms of knowledge growth, particularly constructivism. The dilemmas focus on the relationships between theory and practice in the growth of knowledge in learning and teaching mathematics. The data for this study are drawn from a four-year…

This brief offers an initial look at one science site on the World Wide Web (The Why Files: http://whyfiles.news.wise.edu) in order to consider the educational potential of this technology. The long-term goal of the studies of this site is to understand how the World Wide Web can be used to enhance science, mathematics, engineering, and technology…

This paper focuses on the cultural aspects of research in mathematics learning. The shift to a more socio-cultural emphasis in mathematics education research is valid. The paper explores this point by examining challenges to the former research paradigm. These challenges include culturally-based mathematical knowledge and hidden values in…
