I'd say wave-function collapse is a good approximation for many strong quantum measurements, but isn't able to describe many experiments that involve weak quantum measurements or quantum feedback. As I said it might be good to start teaching quantum measurements using the entanglement+decoherence mechanism first and then introduce wave-function collapse as an approximation.
