Professors Rejecting Classroom Technology

CowboyRobot writes "The January edition of Science, Technology & Human Values published an article titled Technological Change and Professional Control in the Professoriate, which details interviews with 42 faculty members at three research-intensive universities. The research concludes that faculty have little interest in the latest IT solutions. 'I went to [a course management software workshop] and came away with the idea that the greatest thing you could do with that is put your syllabus on the Web and that's an awful lot of technology to hand the students a piece of paper at the start of the semester and say keep track of it,' said one. 'What are the gains for students by bringing IT into the class? There isn't any. You could teach all of chemistry with a whiteboard. I really don't think you need IT or anything beyond a pencil and a paper,' said another."

      To some degree they're right. Computer Science isn't Software Engineering, just as Physics isn't the same as Mechanical Engineering. Its really about data structures and algorithms more than it is about software. You must learn programming languages but mostly as a vehicle to demonstrate concepts.

If an instructor assumes that everybody in the class is comfortable with computers and will actually look at an electronic-only syllabus, it's a recipe for disaster, although I admit that in a computer science department it's probably a safer assumption than usual.

      In one of my classes with over 100 students, it's a month into classes and I still get questions about where the electronic class notes are, even though I explained it on the first day, it's on the syllabus (both on paper and on-line), and it's in the same location for almost every other course at the university.

At least if you hand them a piece of paper in class they don't have the excuse that "they couldn't get it to work" or "my computer was broken", or "my interwebs aren't working from home".

    I am an IT Director / CIO for a small liberal arts university, and I've discussed this issue on my blog about IT leadership in higher ed. What many of us in technology sometimes forget is that technology is fairly new to the workforce, and that includes faculty. Remember, the PC was only introduced to office desktops in the 1980s (unseen mainframes in server rooms don't count). If people enter the workforce in their 20s and retire in their 60s, that's a 40-year work generation. So computers have only been part of the workplace for less than a work generation. There are still a lot of people out there who remember doing their work without technology.

    And faculty are less likely than, say, accountants to embrace change. Accountants realized that they could use the computer to add up the numbers and create a spreadsheet to track the income & expenses. People in sales used the computer to write letters and other communication. But for faculty, their job is teaching and for that they have relied on a chalkboard (or whiteboard) for pretty much their entire careers, going back to undergrad. Powerpoint was a stretch for some faculty, but Powerpoint isn't much more than a "captured" version of their whiteboard talk, so many faculty took to Powerpoint as a means of delivering lectures.

    One of the faculty at my university often uses the phrase "Technology should be like a rock; it should be that simple to use." And there's a lot to that. Faculty want technology that is easy to use. They don't want to tinker with technology, they don't want to try the latest thing. Faculty only want technology when it supports what they need to do for instruction.

    And that's where we in IT see things differently, of course. For us, technology isn't just our job, it's often our passion. We got involved with technology as a career path (programming, desktop support, server admin, databases, etc) because we were pretty much doing that already (building web pages, building our own computers, installing our own OS, etc) and what better job than to get paid doing what you love? So campus technology folks are going to gravitate to the latest technology: the Raspberry Pi, smartboards, video capture, and the like. And we get confused when the faculty don't want to use it, as TFA mentions.

    Faculty will adopt technology when they need it to do the job of teaching. The article includes some quotes along those lines.

What makes it easier for faculty to focus on teaching? Learning how to put a PDF on the web (or a course management tool like Moodle) when they've never done that before, or printing out a syllabus and asking the students not to lose it.

    "What are the gains for students by bringing IT into the class? There isn't any. You could teach all of chemistry with a whiteboard. I really don't think you need IT or anything beyond a pencil and a paper."

    One quote that highlighted when faculty were interested in using classroom technology: "They're undergraduates - you need to attract their attention before you can teach them anything." Because that helps the faculty in the job of teaching students, which is the most important thing. In this case, using some technology in the classroom may help get the attention of students, which the professor says you need to do "before you can teach them anything."

    I'd also remind anyone working in campus technology to remember three important questions when trying to effect change on campus:

    1. Is it the right change to make?
    2. Are the right people behind the change?
    3. Is the campus ready for this change?
  17. Flipped teaching by DragonWriter · · Score: 4, Interesting

    I don't see the point of a lecture anymore. Why not make each class into a movie and show that movie? Then have lab hours to work on the problems.

    This is actually the core of a pretty significant modern trend, "flip teaching" (or "inverted instruction", or a bunch of similar names), in which lecture is done through video (usually delivered online) outside of class time and class time is used for student work with direct instructor interaction, essentially reversing the in-class lecture, out-of-class "homework" model.

    OTOH, if you've spent an entire professional career getting things down under the classical educational model, I can see why you'd be resistant to adopt new models over what you've made work well.
