Q: Does treatment (workbook version vs tutorial version) predict student summative assessment score? A: No. Students in the two treatments, workbook version and tutorial version, did not differ in their summative assessment performance | ||

Treatment (workbook) | − 0.49 ± 3.24 | 0.881 |
Q: Does treatment (workbook version vs tutorial version) predict student summative assessment score controlling for their type of class (Advanced vs Beginner)? A: No. There is not an interaction between treatment and type of class | ||

Fixed predictor | Estimate ± SE | p value |
Intercept | 67.80 ± .2.76 | < 0.0001 |
Treatment (workbook) | − 2.20 + 4.04 | 0.589 |
Type of class (Advanced) | 5.35 ± 4.79 | 0.272 |
Treatment * type of class | 2.33 ± 6.50 | 0.722 |
Q: Do advanced students perform better than beginner students on the summative assessment, regardless of treatment? A: Yes. Advanced students perform better on the summative assessment regardless of which module version they used (workbook or tutorial) | ||
