Description¶
A longitudinal dataset from the Transition and Innovation (TRAIN) study containing standardized mathematics and German achievement, subject interest, differentiated-instruction, and academic-orientation measures for students in German nonacademic-track secondary schools.
Components¶
Claims¶
- Academic orientation mediated the effect of class mean interest on subsequent individual interest in German [+W]
- Within-class heterogeneity in achievement or interest did not directly predict outcomes, but differentiated instruction was particularly advantageous in more heterogeneous German classes [+W]
- Boredom and academic interest fit two separate correlated factors better than one common factor in mathematics and German at every wave [+W]
- Negative boredom–interest factor correlations grew stronger over the four waves, indicating increasing divergence during secondary school [+W]
