A teacher with teaching aptitude encourages students to use active techniques to create more knowledge and then to reflect on and talk about what they are doing and how their understandings are changing. Researchers suggest that teacher’s knowledge of subject matter; student’s learning and teaching methods are important elements of effective teaching, which are very much related to teaching aptitude. Although an educational system has excellent resources, but if the teachers are lacking teaching aptitude and are incompetent or indifferent to their responsibilities, the whole program is likely to be ineffective and largely wasteful.
