Multi-level classes are hard and every class is multi-level. Students in every class have a range of ability. Structure the course to engage everyone, taking advantage of students’ differences rather than ignoring them. For an explicitly multi-level class, such as martial arts or ESL class with beginning through advanced students, you can start by having students work with others of the same level, and then switch to working with students of other levels for a while. You can even pair up advanced and beginning students for in-class tutoring.
– Dan Spalding from his book “How to Teach Adults”
For further thought…
In what ways are your adult Bible studies multi-level classes?
Are there ways you can subtly pair up beginning Bible students with more advanced learners, without calling out either group as such?
Will simply dividing groups up by tables for group discussion allow you a random mix of beginning/advanced learners in each group?
