Experts in the field of instructional design have provided numerous formulas for writing objectives.  Dick, Carey, and Carey (2005) suggest the following steps in developing instructional objectives:

1. Review your goal statement and remember to write objectives based on the goal statement.
2. Write objectives for each step in your task analysis. Objectives are derived from the skills you identified in the analysis. Generally, you should write one or more objectives for each skill listed.

Write an objective for each group of substeps or for each individual substep.
