Eric.ed.gov – Development of an Attitude Scale of Mathematics and Science Teachers towards Mistake and Instant Feedback to the Mistake: A Validity and Reliability Study

The purpose of the research is to develop a valid and reliable attitude scale that can measure the attitudes of math and science teachers (315) and teacher candidates (105) towards mistakes and instant feedback. In the validity studies, the exploratory factor analysis was made with the SPS1S 8.0 package program after that the confirmatory factor analysis was made with Lisrel 8.8 software. To develop the scale; 1. Creation of Item Pool, 2. Obtaining Expert Opinion, 3. Creation of Pre-Trial Form, 4. Factor Analysis is made. According to factor analysis; Kaiser Meyer Olkin (KMO) rate; 0.808; Bartlett test result: 2148,354; Cronbach alpha reliability coefficient for the whole scale: 0.829. According to confirmatory factor analysis: Root Mean Square Error of Approximation (RMSEA) 0.022 (<0.05); p-Value for Test of Close Fit .00 (<0.05), standardized root mean square residual (SRMR) 0.014, Goodness of Fit Index (GFI) 0.75, Adjusted Goodness of Fit Index (AGFI) 0.69; Normed Fit Index (NFI) 0.91; Relative Fit Index (RFI) 0.78; Incremental Fix Index (IFI): 0.83; Parsimony Goodness of Fit Index (PGFI): 0.62; Degrees of Freedom: 760; Root Mean Square Residual (RMR): 2.07 and NonNormed Fit Index (NNFI): 0.88. According to research findings, attitude scale is valid and reliable so it can be used to determine math and science teachers and teacher candidates positive and negative attitudes toward mistake and giving instant feedback to mistake.

Jeg er ansat som adjunkt hos Læreruddannelsen i Jelling, hvor jeg underviser i matematik, specialiseringsmodulet teknologiforståelse, praktik m.m. Jeg har tidligere været ansat som pædagogisk konsulent i matematik og tysk hos UCL ved Center for Undervisningsmidler (CFU) i Vejle og lærer i udskolingen (7.-9. klasse) på Lyshøjskolen i Kolding. Jeg er ejer af og driver bl.a. hjemmesiderne www.lærklokken.dk og www.iundervisning.dk, ggbkursus.dk og er tidligere fagredaktør på matematik på emu.dk. Jeg går ind for, at læring skal være let tilgængelig og i størst mulig omfang gratis at benytte.
