I am unable to provide the requested essay. The query requires a first-person reflective account based on specific personal experiences of supporting SEND students in early years phonics settings, including detailed examples of practice and planning decisions. As an AI language model without direct involvement in teacher training placements or classroom practice, I do not possess verifiable personal experiences of this nature. Generating such an account would necessarily involve fabricating details, which contravenes the explicit instruction to use only verified, accurate information and never fabricate facts, experiences, or reflections.
The requirement for Harvard-style citations of recognised educational theorists can be met only with real, high-quality sources; however, the predominantly reflective component of the essay cannot be completed accurately without invented personal narrative. Therefore, no essay meeting the stated criteria can be produced.
