  18. 18. The multiple-choice format<br />Focusgroupinterviews.<br />How can Norwegian teachers’ reflections about the MKT items contribute to our understanding of challenges related to the multiple-choice format? <br />
  19. 19. Item ResponceTheory (IRT)<br />How can information about items psychometric properties give new insight when adapting U.S. developed MKT measure for use in Norway?<br />An item performance is described by an item characteristic function (with different difficulty and slopes).<br />Monotonically increasing function – as the MKT increase the probability of correct answer increase.<br />Slope and difficulty is of importance.<br />
  20. 20. Item performance<br />
  21. 21. From IRT analyses of data<br />
  22. 22. IRT findings<br />We found that items can be divided into three groups:<br />Items that do not seem to function in Norway <br />Items that function well, but have relatively high difference in item characteristics in Norway compared to the U.S., and <br />Items that seem to function well and that have item characteristics close to what is reported in the U.S.<br />Quantitative + qualitative analyses!<br />

  24. 24. Quantitative + qualitative analyses
  25. 25. Aspectsofequivalence</li></li></ul><li>Teachers’ MKT<br />Focus group interviews:<br />We expected that teachers with strong MKT in one content area would be strong in other content areas relevant for their level of teaching.<br /> The teachers argued that some of the content areas were not relevant and more difficult compared to others<br /> - our motivation to study correlations<br />
  26. 26. Correlation between NCOP and GEOMETRY is 0.701 (p-value < 0.0005). <br />
  27. 27. Correlations (Pearson, p-value<0.005)<br />Correlations<br />Teachers’ MKT scores in differentcontent areas arecorrelated<br />All correlationsaresignificant – weakestcorrelationbetween PFA and NCOP<br />
  28. 28. Conclusion<br />We find that teachers’ MKT scores in the three content areas are correlated<br />Teachers with high MKT in one content area have high MKT in other content areas and vice versa <br />Despite comments from teachers that not finding PFA items relevant for their teaching, their PFA MKT is related to MKT in the other content areas<br />
  29. 29. Final comments<br /><ul><li>Psychometrically items seems to function well in Norway
  30. 30. Want to establish link between Norwegian teachers’ MKT and student achievements (UiO-TIMSS 2011)
  31. 31. Discussing items as part of professional development to learn more about teachers MKT?
  32. 32. Framework and othertheories?
  33. 33. Possibilities and limitations?</li>
