This helps combat teacher burn-out. Recruiting teachers is easier since people can teach through a specific medium in which they have already developed skills and abilities. For instance, someone with a strong background in art may be willing to teach for one month in that medium, whereas a traditional classroom approach would prove more intimidating and less appealing. Workshops take seriously the other ways in which students learn not just cognitively, but also movement, feelings, visual stimulation, imagination, etc. Though there are initial cost in accomplishing the physical changes of the rooms and hallways, money spent on expensive commercial curriculum is saved and used more creatively.
Students gain higher retention of key Bible stories.
The traditional curriculum approach presents a different bible story each and every week, often resulting in weak comprehension and confusion of the biblical story. Teachers learn to teach more effectively. Working on the same lesson form week to week makes the trial and error experience valuable instead of merely frustrating. Workshops enable effective coverage of important teaching elements. In a workshop approach, each of these areas are given full coverage, enabling students to better comprehend, retain, and integrate the stories of the Bible.
