Final answer:
The assessment being used in the described situation is formative assessment, as activities like Grasp Checks and Practice Problems are designed to improve student learning and understanding continuously.
Step-by-step explanation:
The situation described involves various activities like Grasp Checks, Practice Problems, Check Your Understanding, and Performance Tasks that all serve as different types of assessments. Based on the description, the type of assessment being used is formative assessment. This is because these activities are designed to review and reinforce understanding as students engage with the material, rather than to evaluate their final achievement at the end of a course or unit, which would be summative assessment.
Formative assessments are ongoing processes that teachers and students use to gather information to improve learning while it is happening. Grasp Checks, Self-Checks, and Review Questions are tools used to gauge comprehension and offer opportunities for improvement. These tools are not necessarily about grading, but about growth and understanding, which is a key characteristic of formative assessment.
