Representations in Problem Solving in Science: Directions for Practice
Peer reviewed Peer reviewed
Direct linkDirect link
Solaz-Portoles, Joan Josep; Lopez, Vicent Sanjose – Asia-Pacific Forum on Science Learning and Teaching, 2007
In this paper we focus on some of the findings of the science education research community in the area of representations and problem solving. Problem solving depends on the construction and manipulation of mental models (internal representations) in the mind. A large knowledge base (declarative, procedural, strategic, situational, and schematic…

PROVE-ing What You Know: Using a Learning Strategy in an Inclusive Class.
Peer reviewed Peer reviewed
Direct linkDirect link
Scanlon, David – TEACHING Exceptional Children, 2002
This article describes the PROVE strategy, which provides students with learning disabilities with a procedure for naming a concept, providing evidence (both why and how), and defending it. Research results are presented that indicate students with (n=12) and without (n=26) disabilities benefited from the PROVE strategy. (Contains references.) (CR)

Collaborative Learning Processes Associated with High and Low Conceptual Progress.
Peer reviewed Peer reviewed
Oshima, Jun; And Others – Instructional Science, 1996
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…
