What is a surprise quiz that is not graded an example of?

A surprise quiz that is not graded serves as an example of informal evaluation because it provides immediate feedback on students’ understanding and engagement without the pressure of grades. This type of evaluation is often used by instructors to gauge students' comprehension of the material in a low-stakes environment, encouraging participation and honest responses, as students are not worried about their performance affecting their overall grade.

Informal evaluations, like this quiz, allow instructors to adapt their teaching methods based on students' responses and can foster a more open classroom environment. These assessments are often unplanned and can provide insights into the learners' progress and areas that may need more focus.

In contrast, summative evaluations typically occur at the end of an instructional unit to assess what students have learned, while formal evaluations involve structured methods of assessment, such as standardized tests or graded assignments, that are designed to measure knowledge systematically. Non-evaluation suggests the absence of any assessment, which does not apply in this context since the quiz is providing some measure of student learning.
