In addition to strong traditional beliefs, years of slavery through colonization have led to a sense of unity and common struggle in African communities. Therefore, lesson plans in these areas should reflect this cultural sensibility; collaboration and cooperation are key components of successful programs. Teaching techniques that utilize these ideas may include story-telling, experiential simulation, and the practice of indigenous traditions with slight modifications. Every program and lesson must be tailored to the particular community because they almost always learn, live, and achieve as a group or not at all.
