How Facial Analysis Software Could Help Struggling Students
moon_unit2 writes "Tech Review has a story on research showing that facial recognition software can accurately spot signs that programming students are struggling. NC State researchers tracked students learning java and used an open source facial-expression recognition engine to identify emotions such as frustration or confusion. The technique could be especially useful for Massive Open Online Courses — where many thousands of students are working remotely — but it could also help teachers identify students who need help in an ordinary classroom, experts say. That is, as long as those students don't object to being watched constantly by a camera."
beers given as treatment? or is crack more in vogue?

Nice try NSA...
Assignment 12-A is designed to require an average student approximately 20 minutes to solve.
Student #001A solves the problem in 3.5 minutes - Too easy for his skill level
Student #312Q solves the problem in 42.3 minutes - he is struggling and needs further assistance
Problem solved, and you didn't have to spend a dime placing spy-cams at every workstation. You're welcome.
An enigma, wrapped in a riddle, shrouded in bacon and cheese
Because some teachers want to have additional tools to proactively help struggling students that maybe tok shy or embarrased to ask for help. How terrible of an idea that is. Clearly the point of being a teacher is not helping their students, right?
When you graduate and get a job, your boss isn't going to be using those same tools to check in on you to see when you're struggling and need help. Asking for help when you need it is part of the educational process. Giving students a crutch because they are "too shy" to ask for help doesn't really help them in the long run. If they are too shy to ask their instructor for help (the person they are paying to teach them), then how will they ever be able to say to their boss "Hey, I don't think I know how to get starting on this project, can you point me in the right direction".
Besides, teachers already have tools to see when you're struggling and don't know the material - those tools are tests and homework.
While there certainly are some humanities students who get support - most of them do not receive full support from their institution. Typically, half time TA with no tuition coverage. This can also be the case for engineering PhDs at some institutions. Almost all science PhD students are typically guaranteed 2 years TA plus tuition even at the very smallest schools. In addition, non-STEM related PhDs take longer (about 1.5 years longer at the median). This leads to more student loan debt for non-STEM PhDs compared to STEM PhDs. Please see this study for a very nice comparison: The Price of a Science PhD
In addition, you make what I believe to be two assumptions by implication about Universities:
1. That professors are hired to teach.
2. That TAs will do a worse job teaching than professors.
Professors are NOT hired to teach - the exception is small private colleges without graduate programs. Professors are hired to bring research money into the University. The University takes in the region of 40-60% off the top of grants "for institutional research support." While this is not always the case (for some grants, the granting institution require the university to commit matching funds) it is more than the norm. Secondly, while professors are typically more knowledgeable in the subject and typically have more experience teaching (by virtue of spending the time as a TA during graduate school), that does not mean they are the better teachers. The best teachers I ever had were evenly split between professors and TAs. While not scientific, my colleagues experiences were similar.
