Reflecting on your planning, teaching and assessment is increasingly recognised as an effective tool to help improve and develop your teaching practice. Critical reflection involves testing assumptions about teaching and learning and is dependent on having a genuine desire to learn about teaching through informed inquiry. My experience of using the Brookfield model of reflection throughout the PME has informed my understanding of critical reflection and how multiple perspectives should be used to gain a better understanding of your practice. These multiple lenses as Brookfield describes them include yourself, the students, a colleague, and a theoretical perspective. This multi-layered approach to critical reflection has supported me both throughout the SEN differentiation case study, the research report, and day to day lesson planning during my placement experiences. It is essential to regularly evaluate my teaching to find out how effective the teaching methods I implement really are and how they affect student learning. This evaluation is crucial in being able to find solutions to the problems encountered while teaching and in turn improving your teaching practice. While I have developed these essential skills during the PME programme, I seek to further refine these throughout my professional career. Examples of reflections carried out during placement can be found below.
