eric.ed.gov har udgivet: The likelihood-to-act (LtA) survey measures impulsive and analytic dispositions in solving mathematics problems. The current version has 16 impulsive and 16 analytic items. Its validity was assessed using a sample of 27 in-service and 92 pre-service teachers. Both the impulsive and analytic subscales were found to have internal consistency reliability, but they were not correlated with one another. The impulsive subscale was predictive of correctness in classifying the LtA items. The analytic subscale was predictive of how well a participant would perform in Part 2 of a math test after taking Part 1 and being warned that some items could be tricky.

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT Young Black women face dual marginality in the classroom due to longstanding racial and gender stereotypes. However, critical examinations of their academic dispositions remain relatively absent from current discourse on Black student achievement. The mathematics dispositions of Black girls (N = 1707) who completed the High School Longitudinal Study of 2009/2012 (HSLS:09/12) were analyzed through cluster analysis. The results of this study suggest that the mathematics dispositions of young Black women can be characterized in four distinct categories. Within these categories, several trends that carry direct implications for the preparation and motivation of young Black women in mathematics are provided. Link til kilde

eric.ed.gov har udgivet: The Likelihood-to-Act (LtA) survey and a mathematics test were used in this study to assess students’ impulsive-analytic disposition in the context of mathematical problem solving. The results obtained from these two instruments were compared to those obtained using two widely-used scales: Need for Cognition (NFC) and Barratt Impulsivity Scale (BIS). The exhibited correlations of the LtA scores with the NFC, BIS, and a math test provide evidence of the criterion validity of the analytic LtA items, and suggests further revision of the impulsive LtA items to improve the overall measurement validity of the LtA scale. Students LtA scores were found to be marginally correlated to their math scores and correlated to their confidence levels in the math items. Link til kilde
