Inferring Impulsive-Analytic Disposition From Students’ Actions In Solving Math Problems, Kien Lim, Miguel Mendoza Dec 2011

Inferring Impulsive-Analytic Disposition From Students’ Actions In Solving Math Problems, Kien Lim, Miguel Mendoza

Kien H Lim

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 …


Addressing Impulsive Disposition: Using Non-Proportional Problems To Overcome Overgeneralization Of Proportionality, Kien Lim, Osvaldo Morera Jan 2010

Addressing Impulsive Disposition: Using Non-Proportional Problems To Overcome Overgeneralization Of Proportionality, Kien Lim, Osvaldo Morera

Impulsive disposition is an undesirable way of thinking where one spontaneously applies the first idea that comes to mind without checking its relevance. In this research, we explore (a) the possibility of helping pre-service teachers improve their disposition, from being impulsive to being analytic, in one semester, and (b) the effect of using non-proportional situations. This study involves two sections of a mathematics course for pre-service teachers for Grades 4-8. The lessons were designed whenever possible to elicit students’ impulsive disposition so that they could become cognizant of it and make conscious attempts to overcome it. Some test items were …


Assessing Problem-Solving Dispositions: Likelihood-To-Act Survey, Kien Lim, Osvaldo Morera, Mourat Tchoshanov Aug 2009

Assessing Problem-Solving Dispositions: Likelihood-To-Act Survey, Kien Lim, Osvaldo Morera, Mourat Tchoshanov

Kien H Lim

This paper reports an ongoing study that is aimed at developing an instrument for measuring two particular problem-solving dispositions: (a) impulsive disposition refers to students’ proclivity to spontaneously proceed with an action that comes to mind, and (b) analytic disposition refers to the tendency to analyze the problem situation. The instrument is under development and consists of likelihood-to-act items in which participants indicate on a scale of 1 to 5 how likely they are to take a particular action in a given situation. The instrument was administered to 318 college students, mainly pre-service teachers. Statistical analysis indicates that likelihood-to-act items …
