Instruction is the act of bringing information into a realm that can be absorbed and understood by others. This process is invasive, active, and cooperative. A teacher cannot force a student to learn, but a teacher can certainly offer an environment in which learning is available, interesting, and obtainable. Knowing and understanding your learners will help with the preparation of an instructional and learning environment. For example, when I had the privilege of teaching a group of students who each already had a Master’s Degrees in Math Education, I tailored by classroom setting to the assumed average knowledge level of the group. I created activates that would interest, excite, and motive the group. As such, I avoided insulting their knowledge by boring them with a review of arithmetic. Conversely, I created a number of opportunities for them to share their own knowledge and experience. Alternatively, when I worked for the Welfare- to-Work program and taught Preparatory Math to learners who had little knowledge of arithmetic, I certainly did spend a considerable amount of time reviewing the very basics of arithmetic. We used group settings and exercises to mitigate anxiety and abate fear. I made a point to not require any learner to speak in front of the class unless they wanted to. Knowing and understanding a group of learners is a necessity in creating an appropriate, exciting, interesting, motivating learning environment.
