By the end of the lesson, students will be able to accurately define at least 80% of unfamiliar vocabulary words presented, as assessed by teacher observation and checklist. This will be demonstrated through accurate definitions provided in both written and oral responses, showcasing understanding of context and nuanced meaning. Students will achieve this by actively participating in vocabulary-building activities, including but not limited to: contextual analysis of words within sentences and paragraphs, utilizing dictionaries and thesauruses effectively, and participating in class discussions that require the application of newly learned vocabulary. The assessment will focus on the precision and accuracy of definitions, reflecting a comprehensive understanding of the word's meaning and usage. Students will be provided with multiple opportunities to practice identifying and defining unfamiliar words throughout the lesson, receiving immediate feedback to support their learning and progress towards the 80% accuracy goal.
