This is just to see everyone's opinion...
For freshmen chemistry students, should multiple choice be included on exams or no? I've seen professors that have made exams all multiple choice, half multiple choice and half open ended, or all open ended. It seems that in upper level courses, professors tend to give mostly open ended exams (particularly in P-chem).. so giving open ended freshman exams would prepare students for this testing style. However, most professors argue they must give a lot of multiple choice on exams to prepare students for standardized tests such as the MCAT or ACS. I feel with an open ended testing style you can ask more difficult questions and see how students apply the knowledge they learned to these difficult scenarios (isn't that how you can see if a student really learned how to apply the material?). But, with multiple choice, students can get used to answering questions they will likely see on standardized exams. I'm very against teaching to a test but it may be necessary in this case. I'm not a teacher, but this difference in testing style from professor to professor has always interested me.
