Audited a class with him when in attendance at UCLA last year.
I mentioned that I audited the class so you know there is no personal stake to settle, but rather a non-grade related performance evaluation.

Let me preface this by saying I have much admiration and respect for the linguistics and applied linguistics departments, including the majority of its staff and faculty alike. I am known for being honest, respectful, and typically easy on professor assessments simply so you know the degree to which Professor Bachman's personal tact and overall interpersonal skills are severely deficient.

Overall a terrible professor. Disconnected, uninterested, passionate/tenacious--but what good is that if he is not only a sub-par lecturer, but an intrinsically cruel personal individual with little tact in dealing with his students on an individual scope. Appears to have very little concern & interest in teaching and passing on knowledge than his research. Perhaps UCLA should allow research only oriented professors to be given the opportunity to do just that--research only...they should not be allowed to step foot in a lecture hall till they undergo social communications evaluations--as in Professor Bachman's case--the component which is lacking almost entirely.

Unfit for a classroom. Good luck with his classes. I feel sorry for his spouse or significant other. Might seem cruel and tactless myself to say the aforementioned, but no less on point. Don't think I've ever seen a professor at UCLA of which I would reserve similar harsh truths. Most are fantastic at UCLA...not Bachman, he is simply not in keeping with UCLA's tradition of excellence.
