Final answer:
The technique is known as formative assessment, involving observation, monitoring progress, and facilitating knowledge through different activities aimed at practicing and understanding concepts and skill.
Step-by-step explanation:
The technique described in the question, where a teacher observes students during a class period, monitors their progress, and provides knowledge through cues, prompts, or added information is known as formative assessment. This approach includes various activities such as review, organizing information, rehearsing, summarizing, comparing, and more, all designed to give students the opportunity to practice concepts and skills while also allowing instructors to gauge student understanding and progression. Effective formative assessments may involve several different methods, including grasp checks, practice problems, performance tasks, and take-home investigations. These can confirm core conceptual understanding, elicit student explanations, and encourage deeper dives into topics or skills including history-study skill development.
