Hi,
Have you thought of preparing a questionnaire?
You might have some simple questions regarding to your ss � level and their interests.
Some questions might be included:
1- What was the most interesting lesson you have had during the last month?
2- Were the songs, material or submaterials( You name the materials used in that lesson or unit) used in lesson.... good and satisfying?
3- Which type of activities did you get involved in easily?
you can include VAK learning STYLES in your questions according to your last lessons.
Also, what kind of class they �d prefer to have. They may like a certain way of making up their class, the chairs..etc.
Depending on some of these questions, you can take some points (feedback)into consideration and then you improve or reordering your stuff.
Hope you find it useful.
Wish you all the best!
