Using ABCD method to write objectives, teachers must include some important components as Audience, Behavior, Condition and Degree.In this way the teacher is explicit of what his students have to learn during the classes and if they have achieved the standards of performance required to pass the level.
Another choice to write an objective is through Bloom's Taxonomy which is based on three domains:
- Cognitive: mental skills (Knowledge)
- Affective: growth in feelings or emotional areas (Attitude)
- Psychomotor: manual or physical skills (Skills)
