6. Measurement and Evaluation
The Two-Tier Diagnostic Test was administered to both experimental and control
groups as pre-test before the treatment and post-test after the treatment.
Two-way ANCOVA was computed using pre-test and TOLT scores as covariates to
confirm if there were any significant differences in their post-test means attributable to
treatment effect on their achievement.
