Professor Reviews Do Not Provide a Well Rounded Picture for Students

As one semester winds down, college students are busy gearing up the next semester and that means registering for classes. Many students will turn to sites like RateMyProfessor.com to do a little research on the courses and professors before picking their schedule. While these sites can provide help for students, depending on the nature of the source of reviews, many times these sites can fail to present an accurate and well rounded picture of a course or professor's performance.



Depending on where college students look for professor reviews, they may be looking at biased or skewed results. Many sites like RateMyProfessor.com attract students who have strong feelings, either positive or negative, on a professor. Students may have strong feelings on a professor but not have put in the time and effort necessary for the course themselves. An alternative to these third party sites which seem to become increasingly popular at Universities across the country is university sponsored course reviews. This leads to an increase in reviews from students for a more well rounded view of a course and professor.


Students appear to be divided over their views towards online reviews and how they utilize them when registering for courses. UMD Senior, Nicole Gutierrez, says that she has never posted a professor review on sites such as Rate My Professor because she doesn't feel it will sway a student when registering for their own courses, "I just don't think that it actually makes that much of a difference in people's decisions."

CourseEvalUM provides results only for courses where 70% of students in the class participated in the evaluation.

The University of Maryland has its own professor and course review system that it utilizes to track course and professor evaluations from students each semester. Unlike sites like RateMyProfessor, CourseEvalUM is specific to students enrolled at the University of Maryland and only publishes course reviews for which at least 70% of the students enrolled in the course completed a review for so that they can provide a more well rounded review of the course and
professor. UMD students can only view the CourseEvalUM reviews if they have completed their own professor reviews from the semester prior. This works to provide students a more well rounded view of the course than other third party site do. The official UMD course review site is able to send students constant reminders via email to encourage them to complete the reviews. This type of approach to only publishing reviews with a 70% minimum participation rate prevents a polarizing evaluation of the professor. This method prevents courses from having reviews only from students who had a strong enough opinion that they felt the initiative to go write a review for the professor, rather it will gather information from a majority of the course no matter their opinion on the course.

CourseEvalUM restricts access for students wishing to view their professor's reviews to those who have completed their professor reviews for the semester before, which presents a larger number of student input than other review sites. Other course review sites often only attract students who feel very strongly one way or another about a course or professor which does not provide as much of a well rounded evaluation for the course. These sites also do not provide as much data such as grade distribution for the reviews because they do not have the data from the University. However, as mentioned before, the school sanctioned review site requires students to have completed their reviews from the semester before so these third party sites are often a more accessible and convenient choice when registering for classes.

One can often tell a difference in the quality of review from those posted on a University sanctioned site and one such as Rate My Professor simply by the wording and content of the review. Professors at the University of Alabama read and responded their own reviews off of Rate My Professor.

Due to the nature of sites like RateMyProfessor, reviews do not always focus on the actual teaching style or effectiveness of a professor. In an article with The Crimson White, John Beeler, a history professor, said that "sometimes there are those occasional comments about how I changed a student's opinion about history and how I am one of their favorite professors, and that's what I like to see. Unfortunately Rate my Professor worries more about how I dress and how easy my class is rather than how I have influence the lives of many students."

In a NIU poll, students were asked "Do you use Rate My Professor to choose classes," the results were as follows:

  • 35 out of 50 said Yes 
  • Out of those who responded Yes: 
    • 12 said the reviews played a large role when choosing classes 
    • 17 said it somewhat affected them when registering for classes

Studies show positive reviews reflect positive correlation to student’s academic success



When it comes to rating a professor and a course, there are many factors which affect how a student completes a course rating. In a study by Marsh (1987, p. 316), it was determined that there was a positive correlation between the work load and rating of a course. This is an example of utilizing different variable to evaluate a course rather than the personality of the instructor. Often times, students can treat reviews as a popularity contest for finding the most charismatic professor who makes the course enjoyable, but students do not actually feel engaged in the course or feel they are gaining valuable knowledge.



Quality of reviews vary depending on major



When it comes to reviewing professors, a combination of qualitative and quantitative data can be utilized. A professor of statistics at Berkley describes the problem with rating professors quantitatively as the average does not provide an accurate well rounded view.


"If all other instructors get an average of exactly 4.5 when they teach the course, 4.2 would be atypically low. On the other hand, if other instructors get 6s half the time and 3s the other half of the time, 4.2 is almost exactly in the middle of the distribution. The variability of scores across instructors and semesters matters, just as the variability of scores within a class matters. " (Phillip Stark)

On the other hand, qualitative reviews and comments from student can provide a more in depth view into a professor's teaching style and ability, but the reviews can vary by the student's major. Those in a more technical major such as math or science are more likely to leave short responses, while those in the arts and humanities field are much more likely to go into more detail and leave more colorful reviews. This can present the appearance that arts and humanities students feel more strongly about their courses, instead it simply being the result of a difference in personality based on their major.

Online Course Reviews Do/ Do Not Affect UMD Students When Registering For Classes



CourseEvalUM provides results only for courses where 70% of students in the class participated in the evaluation.
-Here I will talk about how the University of Maryland has its own course evaluation system to collect data from students and uses specific criteria for the reviews they include on the site. These have more well rounded reviews due to the reminders from the University.

Insert Video here.
Questions:
-How do online professor and course reviews affect your decision when signing up for classes?
- What has been your experience with a professor and very strong reviews online?
-What sites  do you most frequently use for finding reviews for courses and professors?
-How often do you research a professor’s reviews?

OurUMD, Koofers, and RateMyProfessor among popular third party sites where students can submit reviews for their professors
-discuss how these sites are more likely to present a large amount of negative reviews of professors as the reviews are more questionable. No incentives, such as avoiding reminder emails from the University, which can result in more people looking to voice their negative views

Studies show positive reviews reflect positive correlation to student’s academic success
-I have a study that addresses student reviews and will discuss the findings here

Student evaluation practices have changed over time

http://www.tandfonline.com/doi/pdf/10.3200/CTCH.52.4.134-141



Additionally, I have found the following post from a statistics professor at Berkley which discusses how numerical evaluations of professors can often misrepresent the actual effectiveness of a professor, rather they often are impacted by factors such as ethnicity, gender and attractiveness.  I plan to incorporate this discussion of the different types of reviews that are conducted and how the method can affect the authenticity of the results and thus how helpful the reviews are for future students.

Project iGuardian promotes safe internet practices for parents and kids to keep children safe online


In today’s age of digital dependency and readily available technology for all ages, it is becoming increasingly important to educate children and teenagers on safe internet practices.  With kids using the internet and social media sites at younger and younger ages, it is vital to create a safe and smart space for youths to avoid sexual predators.


Homeland Security Investigations (HSI) works to find sexual predators and prevent child exploitation crimes. In 2014, HSI alongside National Center for Missing & Exploited Children's NetSmartz and the Internet Crimes Against Children (ICAC) Task Forces joined together to launch Project iGuardian. The program works to continue the fight against online child predators at home.


According to the Crimes Against Children Research Center, 1 in 7 teens in the US have been exposed to “sexual solicitations” online.



In addition to their web site which provides tips for kids, teens and parents on being safe online; Project iGuardian also visits schools with law enforcement officials to discuss cyber safety. HSI is working to tailor their outreach programs to provide the most effective educational programs for families. Not only do they provide age-specific programming to the kids, they also speak with the parents in a separate presentation to discuss the importance of parental guidance and control of their children’s internet usage.  

These presentations across the country are done through a partnership with Internet Crimes Against Children (ICAC) Task Forces.  There are 61 of these Task Forces across the country which allow the nation wide initiative to have a personal local impact in communities.

Project iGuardian has created super hero characters to deliver their message to kids in a fun and engaging manner.


 These mascots are featured in trading cards handed out during presentations as well as digital wallpapers for computers and mobile devices. These provide kids with a constant reminder to be careful and alert while they are online.

This program is vital to providing a safe online environment for the younger generation.



The same place where kids can go for learning, creativity and innovation is also becoming an increasingly dangerous place for children.  Unlike the generation of college students who saw technology slowly introduced into our daily lives through the computer and internet, children today have had such technology surrounding them since they were born.  This inherent reliance and comfortability with technology has created an environment where children are less cautious regarding their internet usage.



Project iGuardian and HSI provide tips for safe online use such as:
  •     Only share appropriate pictures you would be comfortable with your family seeing
  •     Utilizing privacy settings to ensure you are only connecting with people you know
  •     Don’t share sensitive or personal information online
  •     Don’t make arrangements to meet in person with anyone you only know through          the internet
  •      Report abuse to an adult you trust


The largest Project iGuardian event yet occurred in San Juan Puerto Rico, where around 8,000 students were in attendance of the three day event. Mayor Vega Borges of Ivelisse Rivera called Project iGuardian a unique and necessary event and expressed his continued support of the work of HSI’s work to both create a safe online environment as well as assist in producing leads in sexual predator cases.  While this event reached a large amount of students on its own, in total there have been 96 presentations which have reached over 25,000 students.


Startling Stats

·      1 in 25 young children have received online sexual messages from unknown individuals       wishing to meet in person
·      Over a quarter of incidents involved an individual asking for a child/ teen to send a photo      of themselves
·      76% of solicitors met their target in an online chat room
·      15% of teens who own a cell phone say they have received sexually explicit (nude/              semi-nude) photos from someone they know
·      Many online sexual predators are honest about their age when targeting youths. Only          5% tried to pretend to be someone younger to meet youths
·      Of a majority of internet related sex crimes involving minors, many willingly met their            predator and 93% of those meetings resulted in sexual contact
