Step-by-step explanation:
An informal method of determining a student’s comprehension and performance of a skill in classroom assessments is known as a formative assessment. This type of assessment allows instructors to confirm core conceptual understanding and elicit brief explanations that demonstrate student understanding. Common formative assessments include grasp checks, practice problems, and performance tasks which challenge students to apply the concepts and skills they have learned in practical situations, enabling them to dive more deeply into a topic or skill. Such assessments are also used to help students better understand the reading through informal analysis, offering a low-stakes, comfortable environment to practice close-reading and prepare for more formal tasks such as essay writing.
