The unit design on weather, which we described earlier,was directed to cognitive,affective,and psychomotor objective.Go back to those objectives and see if you can differentiate between the three domain. It is also possible to achieve such combination in an individual lesson or class. Think back to the Snapshots of this chapter. When Ms.Rennie taught her class about fraction, her objective was for student “to talk about all the ways fraction are used.”She was working on a cognitive objective at the knowledge level.At the same time, she wanted students to appreciate the usefulness of fractions, an affective objective at the responding and/or valuing level.When Mr.Malter taught his math lesson, he had several cognitive objective.At the knowledge level, students were expected to know a formula and to describe the necessary in formation.At the application level,students were expected to use the formula and perform computation,and at the synthesis level,to create a problem of their own. Performing the computations required psychomotor skills of perceptual abilities. As you watched the lesson, you sensed that Mr.Malter intended for his students to feel enthusiastic about math and confident in their ability to perform the computations.Those are affective objective.
