My goal is to both help the Year 7's when it comes to their homework and revising for tests and improve my ways of explaining different material (as I find I lack in that field and I find it difficult to explain to other people. I aim to come weekly over a period of an academic year in order to demonstrate commitment and to build up relationships with students I will help. I will work collaborately with students and two of my peers. We aim to identify students who need extra help and perhaps find innovative ways to improve their skill sets using our own. We will log our evidence through attendence registers from our supervisor and our efforts via our lesson plans.
