This document provides information about unit tests, including their purpose, characteristics, types, and how to plan and construct them. It discusses how unit tests are used to assess student learning at the end of a teaching period, identify student strengths and weaknesses, and provide feedback to improve teaching. There are two main types of unit tests: teacher-made tests developed by the classroom instructor, and standardized tests developed by experts and administered uniformly. When planning a unit test, teachers should consider what knowledge or skills they want to assess, whether to focus on the problem-solving process or final product, and how students will communicate their answers.
