The structure of the help-seeking process in collaboratively using a computer coach in problem-based learning
Research on help seeking with a computer coach providing on-demand help has not produced fully adequate models of the process from a cognitive perspective. The present study postulates a model of help seeking from a cognitive perspective and tests this model in a learning situation characterized as problem-based and computer-supported. The participants were 18 graduate students from the faculty of Education of a Canadian university. Their participation involved solving a complex problem in statistics, in pairs, with the help of a computer coach, the McGill statistics tutor. Analysis of the performance data was performed using directed probability graphs and the log-linear approach. Results show that the model is reflected in the data. Implications for the design of computer coaches and instructional situations are discussed. (C) 2007 Elsevier Ltd. All rights reserved.
