Initially, when I got wind of the decision to revert back to mother tongue to teach Science and Maths in primary schools, my first reaction was a welcome relief.

I had read some research papers that have made inference that learning in one's own mother tongue Science and Maths may be the most effective ways to command these 2 subjects in the first few years of schooling.

I also felt that the increase in the hours of teaching English as a subject is a welcome first step to bring back excellence in the learning of English.
