Inferring impulsive-analytic disposition from students’ actions in solving math problems
The research reported in this paper is part of a larger study designed to investigate the validity of the Likelihood-to-Act (LtA) survey—an Likert-scale instrument, currently under development and testing, for assessing students’ impulsive-analytic disposition in mathematics. Transcripts and videos of 15 interviewees’ responses to five problems, adapted from the LtA Survey, were analyzed in terms of (a) solution strategies, and (b) impulsive-analytic disposition. Two scores were derived from quantifying the codes that were assigned to the 75 problem-solving episodes. These scores were highly correlated to one another and were correlated to the LtA_Difference (impulsive minus analytic) score, obtained from the LtA Survey administered several weeks prior to the interviews. These results can be taken to support the validity of the LtA instrument.
