Stretching and Challenging Learners

I am going to research how to stretch and challenge my students during their lessons. The phrase “stretch and challenge” can relate to the whole class, and be included within the lesson to the whole class, but equally it can be interpreted to mean pushing the most able students to think beyond what has been taught, perhaps focusing on the implications of what they have learned or evaluating the effectiveness of a particular model or method. I am interpreting “stretch and challenge” to mean the stretching of all the students within a class to suit their ability level. I want all my students to feel challenged in the lesson and to overcome these challenges. What is a challenge to one student will be different to another student and I would like to adapt my teaching methods to reflect this.
