Different Approach for Tinuk S'nishba

See the book Rav Weinberg talks about chinuch, pp. 109-100. He gives a whole speech about how children should be taught the plain meaning of Chumash and not fancy peshot because they'll be able to build on the plain throughout their lives, but if you give them too many explanations that will actually limit them because they'll get stuck on what they heard in 8th grade. He adds however that this does not apply to kiruv. There you are not teaching Torah but are trying to win them to a place where they'll be interested in Torah. "And for that you can do whatever will most effectively make them interested and respond to you." I believe he (and others) offered similar comments about resolutions to matters such as Darwinism and Cosmogony. It's one matter what you teach to frum kids and another to tinuk sh'nishba.
