Final answer:
The teacher is using a strategy that includes practice and assessment, grasp checks, and self-assessment as students grade and correct their own quizzes to reinforce learning.
Step-by-step explanation:
The learning strategy implemented by the third-grade teacher involves practice and assessment, where she combines formative assessments and self-evaluation. Students first look up answers during a pop quiz, which serves as a grasp check to review their understanding of the material.
By grading and correcting their own quizzes, students engage in self-assessment, which helps them identify areas for improvement and reinforce learning. This process also incorporates repetition, as the same quiz is used the following week, allowing students to apply their knowledge again and track their progress over time.
