Hi Roger: Someone once said" experience is someone with a history of mistakes behind them". So I guess we experienced folks have made a lot of mistakes! Matching content to student need requires a thoughtful, resonsible process that really should be done by professionals who have had training and/or education in curriculum design (you know, experienced!) But assuming the basic curriculum is completed choosing the media, resources and materials needed for effective courses also takes thought, time and effort, and planning. Making adjustments based on observation, student performance, or feedback is critical for improvement to occur. I'll say it'll never be perfect, as student and course content is dynamic and always changing. Regards, Barry
