The last step of each module is to make explanatory notes so you can serve your disciple-in-the-making in this process. "Teaching you to Teach True^North" is the best outcome I could hope for.
Obviously, to teach a lesson or a skill like Observation and all of its nuances requires someone to know the material. In reality, the only way to become proficient at Observation is to practice...practice...practice. Additionally, to disciple...disciple...disciple. The real test is "Are you becoming a Disciple-maker?" not "Can you take an objective test on basic Observational Skills and get at least a 75%?
It might be quite interesting for people to take turns in the Small group and try (using your own words) to explain the process of Observation from start to finish.
