This document outlines the key parts of an interactive lecture presentation on diagnosing the fundamental constituents of an essay. It discusses educational hooks, objectives, standards, and the main parts of an essay including the introduction, thesis, topic sentences, evidence, conclusion, and more. Students are engaged through think-pair-share activities, guided questions, examples from articles and their own experiences, and are asked to analyze texts to identify these essay elements. The goal is for students to understand and be able to classify the important components of compositional writing.
