How Big Data Is Taking Teachers Out of the Lecturing Business: Scientific American - 0 views

  • David Heckman, a mathematician, was accustomed to lecturing to the class, but he had to take on the role of a roving mentor, responding to raised hands and coaching students when they got stumped
  • alarmingly high numbers of students showing up on campus unprepared to do college-level work.
  • Like institutions at every level of American education, it is going through some wrenching changes. The university has lost 50 percent of its state funding over the past five years.

  • more efficient way to shepherd students through basic general-education requirements—particularly those courses, such as college math, that disproportionately cause students to drop out
  • That fall, with little debate or warning, it placed 4,700 students into computerized math courses. Last year some 50 instructors coached 7,600 Arizona State students through three entry-level math courses running on Knewton software. By the fall of 2014 ASU aims to adapt six more courses, adding another 19,000 students a year to the adaptive-learning ranks.

The trouble with Khan Academy - Casting Out Nines - The Chronicle of Higher Education - 2 views

  • Let’s start with what Khan Academy is. Khan Academy is a collection of video lectures that give demonstrations of mechanical processes. When it comes to this purpose, KA videos are, on the average, pretty good. Sal Khan is the main reason; he is approachable and has a knack for making mechanical processes seem understandable. Of course, his videos are not perfect. He tends to ramble a lot and get sidetracked; he doesn’t use visuals as effectively as he could; he’s often sloppy and sometimes downright wrong with his lecture; and he sometimes omits topics from his subjects that really need to be there (LU decomposition in linear algebra, for example). But on balance, KA is a great resource for the niche in which it was designed to work: giving demonstrations of mechanical processes.
  • But let’s also be honest about what Khan Academy is not. Khan Academy is not a substitute for an actual course of study in mathematics. It is not a substitute for a live teacher. And it is not a coherent curriculum of study that engages students at all the cognitive levels at which they need to be engaged. It’s OK that it’s not these things. We don’t walk into a Mexican restaurant and fault it for not serving spaghetti. I don’t fault Khan Academy for not being a complete educational resource, because it wasn’t designed for that purpose. Again, Khan Academy is a great resource for the niche in which it was designed to work. But when you try to extend it out of that niche — as Bill Gates and others would very much like to do — all kinds of things go wrong.
  • When we say that someone has “learned” a subject, we typically mean that they have shown evidence of mastery not only of basic cognitive processes like factual recall and working mechanical exercises but also higher-level tasks like applying concepts to new problems and judging between two equivalent concepts. A student learning calculus, for instance, needs to demonstrate that s/he can do things like take derivatives of polynomials and use the Chain Rule. But if this is all they can demonstrate, then it’s stretching it to say that the student has “learned calculus”, because calculus is a lot more than just executing mechanical processes correctly and quickly. To say that it is not — that knowledge of calculus consists in the ability to perform algorithmic processes quickly and accurately — is to adopt an impoverished definition of the subject that renders a great intellectual pursuit into a collection of party tricks.

  • Even if the student can solve optimization or related rates problems just like the ones in the book and in the lecture — but doesn’t know how to start if the optimization or related rates problem does not match their template — then the student hasn’t really learned calculus. At that point, those “applied” problems are just more mechanical processes.
  • Khan Academy is great for learning about lots of different subjects. But it’s not really adequate for learning those subjects on a level that really makes a difference in the world. Learning at these levels requires more than watching videos (or lectures) and doing exercises. It takes hard work (by both the learner and the instructor), difficult assignments that get students to work at these higher levels, open channels of communication that do not just go one way, and above all a relationship between learner and instructor that engenders trust.

How Big Data Is Taking Teachers Out of the Lecturing Business: Scientific American - 1 views

  • Any accurate evaluation of adaptive-learning technology would have to isolate and account for all variables: increases or decreases in a class's size; whether the classroom was “flipped” (meaning homework was done in class and lectures were delivered via video on the students' own time); whether the material was delivered via video, text or game; and so on. Arizona State says 78 percent of students taking the Knewton-ized developmental lecture course passed, up from 56 percent before
  • in Japan, where it is common for managers who have studied English with the adaptive-learning software iKnow to list their iKnow scores on their resumes.
  • “The reality is that it's going to be done,” says Eva Baker, director of the Center for the Study of Evaluation at the University of California, Los Angeles. “It's not going to be a little part. It's going to be a big part. And it's going to be put in place partly because it's going to be less expensive than doing professional development.”

Salman Khan: Let's use video to reinvent education | Video on TED.com - 83 views

  • Salman Khan talks about how and why he created the remarkable Khan Academy, a carefully structured series of educational videos offering complete curricula in math and, now, other subjects. He shows the power of interactive exercises, and calls for teachers to consider flipping the traditional classroom script -- give students video maths to watch at home, and do "homework" in the classroom with the teacher available to help.

'Interactive Learning Spaces' at the center of Ball State U.'s faculty development program @insidehighered - 29 views

  • The rooms are part of a larger faculty development program intended to promote active learning techniques and cut down on lecturing
  • university is researching whether teaching at-risk students -- those withdrawing from or earning a D or F in a basic math course -- in the classrooms could improve academic outcomes and, eventually, graduation rates.
  • Pavlechko described the two spaces as “intake classrooms” -- faculty members who work in the development program are required to teach in them for two semesters. By the end of this academic year, the classrooms will have hosted 68 faculty members representing 29 of the university’s 48 departments and more than 3,500 students.
  • ...5 more annotations...
  • How do we set ourselves apart? In our case, by the development of these interactive learning space classrooms, we are demonstrating to everyone that we are committed to the concept of faculty development.”
  • researchers found at-risk students who took the course in classrooms that promoted active learning (which included some rooms other than the renovated ones) were 2.8 times more likely to succeed -- that is, to earn a grade higher than a D -- than students in traditional classrooms.
  • The company has surveyed hundreds of students and faculty members at the universities it has worked with, and says it has found a statistically significant correlation between classroom configuration and student engagement. The survey doesn't include any academic results.
  • “We actually found a fairly moderate to strong correlation between what they think of these areas and if they think they have the ability to get a higher grade -- or their motivation to attend class and also their engagement in class,”
  • “Perception-wise, students are telling us ‘I can do better when I’m in these spaces,’ ” Jones said. “Maybe that’s enough of a win?”
