I found planning and preparation very important in my teaching carrier. Especially the preparation of lesson notes. I have been instructor at many levels of education and have attended a lot of courses both in Africa and in the UK. In the Elementary and Middle school level teaching in some country where practice my teaching profession many years ago, it was compulsory for a teacher to prepare a lesson plan and lesson notes. These prepared documents are constantly inspected and approved by authorities. Failure to do so most of the time leads to sanctions.
