Extending research on the Marsh/Shavelson model of self-concept, a set of 14 academic self-concept scales was related to school performance in 8 school subjects for a sample of 507 high school students. Correlations between matching areas of self-concept and achievement (0.45 to 0.70; mean r=.57) were substantial and larger than correlations…

The assessment method used three real-life problem situations crossed by six generic skills, namely Decision-Making, Communication, Analysis, Synthesis, Valuing and Execution.

Equivalence in reliability and validity across 4-point and 6-point scales was assessed by fitting different measurement models through confirmatory factor analysis of a multitrait-multimethod covariance matrix. Responses to nine Likert-type items designed to measure perceived quantitative ability, self-perceived usefulness of quantitative…
