I sympathize with you completely. I was in a similar situation 20 years ago when I began teaching CCD. I realized how much I didn’t know becaue of poor catechesis in CCD during the 60s and 70s (We sang "Jeremiah was a bullfrog…Joy to the world!) and how much my students didn’t know (7th graders not knowing prayers, etc.).
As for teaching CCD, other posters gave excellent suggestions. I had to supplement the lesson with a lot of materials. Also, don’t be afraid to give homework, worksheets, and tests. I truly believe that faith formation is multi-faceted and one of those facets is study. In increasing our knowledge, we increase our understanding, and, thus, increase our commitment. Tried and true study tools work with vocabulary and basic understanding. Also, sending home worksheets with kids where the parents have to help may bring catechesis to the home where it is needed. It also sends the message that faith formation is not just an hour a week obligation.
This situation also influenced our decision to send our children to a Catholic school. The Catholic school can combine the study aspect along with the practice of our faith. Daily prayer with their peers, weekly Mass, and seasonal devotionals are important in developing a personal faith and fostering the faith community.
When you are asking questions at your local Catholic school, ask for the school performance on the NCEA ACREs tests. These are tests developed by the National Catholic Education Association to evaluate religion programs. Our diocese administers these tests at various grade levels (in the Catholic schools, not in the CCD programs, hmmmm?) to detemine student’s knowledge. The school can give aggregate statistics. This could be an indicator as to how well the school does in teaching the faith.
A little story. My oldest son went to 13 years of Catholic school, K-12. His roommate at college also went to Catholic school and came from a devout Catholic family. The boys had a crucifix on the wall and statues of the Infant of Prague and Our Lady of Guadalupe. During his first weeks at college, a boy down the hall came into his room and asked: “Is that one of those Rosemarys” of the Rosary on the nightstand. My son and roommate were incredulous that someone wouldn’t know what a Rosay was, especially since the boy was Catholic! (CCD, Sacraments, Confirmation, etc.!!) My conclusion: His family not only failed him in teaching him our beautiful faith but so did his faith community.
