Let's assume that your primary concern for caring about your rating is that you want students to see you in a positive light for some reason that you hold dear. Further assume that this is personal for you, and you recognize that RateMyProf reviews do not hold much weight for your chances of tenure.
There are two very common scenarios that happen when the average student visits RateMyProf. It is typically your average student that will put weight on RateMyProf, and it is typically the average student that will spend time writing a review for you on RateMyProf, so keeping the average student in mind is important. I believe then that there are two types of profiles on RateMyProf that very accurately reflect how professors are when they put their teaching hats on (of course, sample size is huge here):
- You generally have a high score, positive comments, and a few comments that suggest you probably got a PhD in tormenting students in classrooms.
The students will notice that the majority of comments and ratings suggest you are a great teacher, you care about your students, and most importantly you are good at teaching the average student (this seems to be the case you fall under). Students will accurately be able to flag the relatively small number of negative comments and assign those as problems on the part of the student writing that negative review. After all, there really is nothing to gain by students from writing a good review for you other than that they appreciated you as an instructor. On the other hand, in this scenario, the incentive to write you a bad review is driven by spiting you, and it's pretty easy for the average student to recognize when that is happening.
- You have a low to low-medium score, a record of bad-subpar reviews by the students, occasionally there are some shining reviews among all of the bad ones
Students viewing this type of profile will probably be correct in their assessment of your inability to teach to the average student. Students looking at a profile like this will likely identify that, for some reason or another, your teaching style is not suitable for them and that students are probably being more truthful about their negative reviews then the outlier of the previous scenario. It is much more telling when many students write bad reviews, because it indicates a pattern of poor communication instead of an outlier. On the other hand, students looking at this type of profile will notice some of the 'glowing' outlier comments and probably recognize that those students are the ones that are either harder workers or are relatively gifted to their peers and would have succeeded anyways. To the average student, those great comments don't hold any value because it does not apply to them.
There are other scenarios that are more difficult to distinguish, particularly those of average score, because the lack of polarity makes it difficult to assess what is going on. But based on my experience as a student that has used RateMyProf to help me choose courses, and from many conversations I have had with friends in the fraternity/sorority system as well as other student organizations, many of the average students can accurately assess (with a sufficient sample size of reviews) whether a professor is going to be a good or bad educator/instructor for the average student.
