The basic idea of BTSA revolves around a veteran teacher, called a Support Provider, being matched up with a begining teacher for a period of two years. These two work together closely during the induction period. SPs are selected according to selection criteria and go through rather extensive training. They observe and coach their BTs. They work with them on a daily basis to plan instruction, problem solve, and to offer support.
Emphasis is on reflection that changes and informs practice.
In California we have the California Standards for the Teaching Profession and that is the lens we use to observe and reflect on practice. We make use of self-assessment of teacher practice. From the self-assessment, the BT and SP identify inquiry questions in which to look objectively at teaching and to change what they do to make it more effective for students. It has been a highly successful project statewide. I am involved with one of the original projects and one of the newest ones.
