... b-based learning model, i.e., online and blended learning, and face to face approach on the scores achieved in teacher training.

Findings suggest that the web-based learning model is more effective in teacher achievement than the f2f, while the female tends to be better than male. Hence, digital constraint is not an obstacle for the teacher in the web-based model. Interestingly, blended learning that emerged as a new trend in e-learning proved to be quite promising. These findings provide considerations for the development of a policy for an appropriate TPD model for teachers at different levels.
