Categorization and Representation of Physics Problems by Experts and Novices
Examining organization of semantic information in the domain of Physics for PROBLEM SOLVING for experts versus novices: 1. Use of problem categories (models) to solve problem 2. Types of problem categories used 3. Knowledge associated with problem categories 4. Features of problems that affect how problem represented Operational definitions: PROBLEM REPRESENTATION: is a cognitive structure corr...

ed solution methods. In particular, when asked to develop and state "a basic approach," they did one of two things. They either made very global statements about how to proceed, "First, I figured out what was h a p p e n i n g . . . then I, I started seeing how these different things were related to each o t h e r . . . I think of formulas that give their relationships and then . . . I keep on ...
متن کاملPatterns of Multiple Representation Use by Experts and Novices during Physics Problem Solving
It is generally believed that students should use multiple representations in solving certain physics problems, and earlier work in PER has begun to outline how experts and novices differ in their use of multiple representations. In this study, we build on this foundation by interviewing expert and novice physicists as they solve two types of multiple representations problems: those in which mu...
متن کاملSemi-Automated Analysis of Protocols From Novices and Experts Solving Physics Problems
PDP (Protocol Diaqnostic Program) is a proqram for analyzing think-aloud protocols of subjects solvinq elementary physics problems *. Two versions of PDP implement models of problem solving behaviour at novice and intermediate levels of expertise. In order to compare the behaviour of the models with think-aloud protocols of subjects, PDP is equiped with a think-aloud component, which communicat...
متن کاملHow Does Visual Attention Differ Between Experts and Novices on Physics Problems?
Research in many disciplines has used eye-tracking technology to investigate the differences in the visual attention of experts and novices. For example, it has been shown that experts in art and chess spend more time than novices looking at relevant information. Thus, it may be helpful to give novices more direct insight into the way experts allocate their visual attention, for example using a...
