Integrating Educational Technology into Teaching. As a teacher you will constantly assess the learning of your students. As a part of each lesson, you will assess their understanding and accomplishment of the learning objectives of the lesson. When necessary you will reteach material based on assessment. This type of constant assessment is often fairly informal.
More formal assessment results in student records.
It may lead to grading, or it may mark a milestone in achievement. When a large group of students have taken the items, item analysis can measure the effectiveness of each item. An individual teacher, then, can select items from the pool and feel assured that the items will accurately measure student performance relative to other students who have taken the course. When there is a fairly large pool, it can allow for make-up tests when a student is absent, allow creation of several versions of a test for different students in the same room or in different class periods. Tests from test generators can often be administered electronically, too.
