Clickers Redefining Classrooms 228

Posted by Zonk from the talking-without-talking dept.
markmcb writes "It seems that teachers may have a new way to boost classroom participation using a device called a clicker. A clicker is a small handheld device that allows its user to wirelessly respond to various prompts selected by a teacher. So when a teacher wants opinions on topics that people tend to shy away from like sex, religion, and politics, the question can be asked and the students can answer anonymously via the clicker. Everything from a simple poll to a graded quiz can be conducted using the device. In the age of cell phones and wireless computers such a technology is likely to be well-received by students, but one can't help but wonder if such a device will breed less assertive graduates who lack the will to stand up and voice their opinion on sensitive issues."

      These things take up valuable class time trying to get them to work in the first place, only work via line of sight... which you think wouldn't be a problem in a smallish classroom (if they are even working at all) and just are a huge distraction.

      Georgia Tech uses this device for some intro Physics Classes and some CS Classes.

      The device we use iPRS [com.com] uses just a simple infrared signal. In a class with 300+ Students there are several readers mounted in different parts of the room since the device has a relatively short range.

      • No more than one person can submit an answer at any time (thus you have to keep trying to send it until it goes through, you see your name/number change color).
      • You have the possibility to change you answer a certain number of times.
      • The software is available in the lecture pc's and easily analyzable.
      • The device will send a short message that includes: ID # of the Reader & Answer specified

      The PRS response was required as part of the grade for the class (10%). A group of us (CS Majors) started thinking on ideas on how to around this. The first solution we implemented (Before we were able to translate the IR message into clear text) involved "recording" each of the answers from our group, thus one person sitting in the class could answer for all of us through his laptop. We later switched to an IR-Equipped Ipod [engadget.com].

      That was ok but the person answering did not always answer the correct question (answering correctly gave you extra points). We were later able to decode the messages from the IR signal. And that's where things got fun.

      We placed a laptop sitting nearby one of the "sensors" (end of white strip, on wall) and just analyze all the data coming live. We had about 30-60 seconds to answer thus we could analyze the data up to 25 - 55 seconds, estimate what the most "popular" answer was and then submit all of ours answers at the last second. That gave us almost 100% accuracy since whenever the class erred, the professor would step back, re-explain the problem and then see if the answer was right.

      We used iPods, laptops and a CS-classroom-issued-Ipaq. The ipaq would eventually analyze the data through it's own high speed IR port and then send out our "responses" through a mp3 file (that came out of the IR device [griffintechnology.com]).

      Also: the system is usecure, it is easy to skew the statistics by introducing new users to the system or to overwrite your ex gf's answer.

      Although there was very little benefit, beating the system felt good!

    • Ugh- textbooks cost enough without having "clickers" bundles in.
      Call me crazy, but if students aren't comfortable sharing their opinions in class or joining the discussion, then maybe the profs need to cultivate a better atmosphere for discussion. I personally wouldn't want a class to degrade into one of those bar remote control trivia games.

        The only problem is that the normally less assertive will only be assertive with a clicker. The clicker can be a good start but it has to be viewed like a security blanket.

      I had to sit through a class at MIT rife with stupid ideas like this.

      Just one? Siiigh, here I go, likely to get modded flamebait, but what the hell. I've talked to numerous MIT students (ranging from current undergrads, to PhD's) in several different fields (mechanical engineering, electronics, etc). I also worked for MIT (see below).

      MIT is "rife", like many "top" schools, with professors who barely show up for the classes they supposedly "teach". TA's run the class, do the grading, and interact with the students. Meanwhile, the professors are busy doing the traditional MIT professor path: invent something, patent it, form a company, get rich off it. MIT has an entire office full of patent attorneys, called the Technology Licensing Office- where I worked for a bit. They measure revenue in hundreds of millions of dollars. MIT has turned into an R&D mill; the Media Lab is a perfect example. MIT's best and brightest from the Media Lab have turned out...a shag-rug-covered alarm clock that rolls off the table when you hit the snooze button. Slightly clever, very half-baked, and utterly lacking in anything even remotely approaching state of the art in -any- field. But it's from an MIT student, from the Media Lab no less, and their shit is gold and smells of rose blossoms- so it gets local, national, and international coverage, and nobody says "hey, this is just an alarm clock with two wheels and motors that turn on for a random bit of time". Ie, something a smart 8th grader could make.

      I went to a college where I was on a first name basis with my CS professors, their significant others...even knew their kids, and I'd bump into them on campus at concerts and stuff. I could, during their fairly wide office hours, walk into their office, plop down on the couch, and ask them questions about the current homework assignment or project. I knew most of the kids in my classes (the largest, an "intro" level class, was 25 people). You know what? I actually learned stuff, and not just what was in my textbook.

      Maybe if MIT professors actually taught their classes, class size would be smaller, students would feel more involved (and hence as questions more often during a lecture) and the quality of the lecture would be such that fewer questions would be necessary in the first place.

      Some will argue that MIT's professors, focusing on research, are its strength. Except to undergrads, they'll never get even close to this state-of-the-art research. The professors who come up with truly revolutionary stuff are usually the furthest removed from students. "Top" schools all sell the same lie the armed forced do- "join us, work on cutting edge stuff!" Well, funny thing that you join, and find yourself cleaning lab equipment. Hey, it's a step up from cleaning toilets in the Air Force general's jet, I guess.

    I recently went through the transistion in my previous college to not having these clicker type devices to having them. We call them PRS. Don't remember what it stands for..

    But anyways, it takes all the fun out of college. At the beginning of class, the prof will require everyone in attendence to "click" into class. You have to point your unit at some sensors and then via wireless signals the computer records your attendance. Thus, every professor on campus is now taking attendence this way. No fun anymore, because you must attened every class, or your grade automaticaly drops.

    Of course, this has it's puropse, and is a great motovational tool. A few of my friends have even reverse eng'ed the deivce and when they're feeling mischivous enough, disrupt the signal enough for the PRS recieving unit to go haywire and throw an error on the screen - thus ending the attendence taking or the quiz taking or what ever. I suspect that these people have learned more from studying the device then any bullshit 2nd/3rd year comp sci course could teach them.

    Devices like these are a major form of social control. Awful for educational purposes, at least so says any student who's had to deal with the little bastards.

    But then again.. when it comes time for me to be the grad student teaching, I'm sure I'll use it. Damn maturity.

    I actually got stuck in a sample class using these, and I'm not a big fan. What happens is the teacher will ask some multiple-choice question, then he has to stop talking for several minutes while he switches to the clicker server program. The whole class strains and points and tries to get the sensors in the room to pick up their answer. There isn't any indication if it was *your* clicker which was picked up by the sensor though, so everyone just keeps clicking. They have to constantly check the screen to make sure that their number was picked up - which doesn't always happen.
    Maybe it's just because they're new, but the teachers I had tried to avoid using the clickers for points. I'm sure the teachers got some decent feedback - knowing what people understood and didn't. Then again, they were in my physics classes, so it was easy to formulate questions and get responses in a "short" amount of time. I certainly appreciated that over homework questions. It did help once or twice to let me know I misunderstood something, but overall, they were very frustrating, and grew to be one of my pet peeves.
    • Don't mistake a bad implementation for a bad concept. I'd love to hear from a class that didn't have the bugs yours did, to get a true evaluation of the concept. The article mentions enhancements of integrating questions into a powerpoint presentation to prevent the in-class delays, and a red/green indication on individual devices to make sure the responses were received.
  • I used these in social science class in 1992 in Sweden, they weren't wireless though of course. I was 16 at the time ("Gymnasiet" in Sweden, not sure what it is called in other countries - secondary high?)

    Quite fun, we students got to write yes/no questions and passed them to the teacher, she selected the most interesting ones. I would have been interested to see the answer to the question "Do you consider yourself gay or bi", but I chickened out.

    Memo to college professors: if you have 400 students in your physics class, you can't really do much to increase student participation. There, I said it. What, do you think having a database tabulate responses to your questions like some maniacal Nielsen-for-classroom-instruction is going to make this room feel like it has fifteen students in it? Survey says: no (+/- 80% due to equipment malfunction).

    I majored in Japanese and CS in college (at a university with very small average class sizes compared to large state schools like the ones in the article). The difference between a 12-man discussion section and a 90-man lecture is like night and day. When there are 12 you can tailor your lessons to the room and if Billy is skipping class or obviously not getting the material despite trying you will know, instantly. When there are 90, you probably get to know those 5 kids who are really too good to be in this class and those 10 who use every trick in the book to avoid getting out of doing assignments, and for the 75 students in the middle you're lucky if you even know their names. (My best CS professor, ever, had academic standards about as sharp as a butter knife and lecturers which did not succeed in imparting much material but he knew *every* kid in the class and worked the labs like it was his job to the point where he knew some of the 15 team's project status better than the lazier team members did -- nothing says "I care" like "Hey, Bob, how's it going? Did you guys get that regexp engine working right for the poetry project yet? Time's a wasting, remember there are other ways to skin the cat. Anyhow, if you need to chat about it come see me after class or on Thursday. Hey Suzy! I loved the design on the last project but this is AI, not the perl obfuscation contest. More comments on the magic bits next time, OK? Hey Joe! I haven't seen you in three weeks?. Should I be concerned or is this just 'This is not a class I care for?' in which case I can just give you a B- and write you off?")

    • Which is an EXCELLENT reason to use the money to HIRE ANOTHER TEACHER than buy these clickers. Geeze, I wonder how much money all these "systems" are wasting. Software, hardware, support, contracts. Wouldn't just be easier to have another teacher there to actually engage students?

    People who are afraid to voice unpopular opinions will probably not be made more bold in any event.

    I recall watching a tv special about the use of this sort of device. One trend was that when used in a "Do you understand" type of question, the teacher can get a much better idea about how well the lesson is being understood, and can go over it again.

  • Seems like most of the comments are complaints about lousy implementations. Perhaps a better way to do this sort of thing would be to hardwire the clickers into the room itself (into the armrests/desks) and use wires under the floor instead of wireless.
