I have been challenged by your evaluative comments about children's Sunday School Bible teaching in your book, The Bible Story Handbook. Your childrens' resource bibliography in your book is now 9 years old. What additional resources have you discovered in the past 9 years, and which of those you've listed would now be excluded from your recommendations? What resources have you and your wife discovered that would capably inform Sunday School lesson writers about the educational "learning" development of elementary school children through highschool regarding biblical-theological ideas (congruent with modern research in learning & age development theory) that are age appropriate and inappropriate for these children & youth in their stage of development?
