“If we can solve this,” he said, “I think it will disrupt all of higher education.”

John Hennessy, Stanford’s president, gave the university’s blessing to Thrun’s experiment, which he calls “an initial demonstration,” but he is cautious about the grander dream of a digitized university. He can imagine a virtual campus for some specialized programs and continuing education, and thinks the power of distributed learning can be incorporated in undergraduate education — for example, supplanting the large lecture that is often filled with students paying more attention to their laptops. He endorses online teaching as a way to educate students, in the developing world or our own, who cannot hope for the full campus experience.

As The Times’s Matt Richtel recently reported, there is remarkably little data showing that technology-centric schooling improves basic learning. It is quite possible that the infatuation with technology has diverted money from things known to work — training better teachers, giving kids more time in school.

“When is the infrastructure of the university particularly valuable — as it is, I believe, for an undergraduate residential experience — and when is it secondary to the learning process?”

The launch this year of Google Voice — representing as it does a free alternative or complement to costly language laboratory recording hardware and software — has profound and exciting implications for student engagement in general and the confluence of language instruction and cell phone technology in particular. The proliferation of cell phones among today’s students combined with the development of such new computer-mediated communication tools allows teachers to engage students in new ways in and out of the classroom.

My Google Voice number has served primarily as a messaging service students call (sometimes spontaneously during the instructional period, more often outside of the classroom) to record dialogues, poetry, even song, either individually or in pairs. These recordings are stored on Google servers, but can be downloaded and posted on course management pages (Moodle, Blackboard, Sakai, etc.) or podcasting, blogging, or social networking sites (I post particularly good recordings on my Spanish Facebook page).

maximizing student engagement during the class period is essential, as many students work and do not practice outside the classroom setting. Without getting into the debate over the front-end need for considerable comprehensible input, as a practical matter many students see paired work time (particularly in larger classes) as social time, which can lead to student-teacher conflict (no explanation needed).

for lower level classes I can instruct my students to form small groups and, within a given time frame, call my Google Voice number and record a narration of an illustration or picture sequence. In the higher level classes, I can ask groups to come up with a succinct recorded comparison/contrast analysis of two different perspectives (textual and/or auditory) on a given subject. Either way, embracing whole language oral output turns the focus from the particulars of language and writing to whole language and pronunciation. It also allows for efficient instructor identification of common problem points.

It is generally accepted that students work harder and become more engaged and invested in activities and assignments that might be publicly posted (on the Internet or otherwise). My own experience shows that students required to record speech of any kind in a computer laboratory setting spend considerable time preparing prior to recording. The very act of recording their voices — creating a permanent record of their speech — instilled a strong desire to perform well. In short, the act of recording increased students’ investment and engagement in the learning process.

on a post-recording survey of a Spanish 3 class of 21 students, I asked students to respond anonymously to the following survey question:“I practice my Spanish pronunciation before calling Google Voice… not at all once more than once repeatedly”A total of 89 percent of the 21 respondents answered either “b,” “c,” or “d,” with 26 percent responding “repeatedly.” Among the more entertaining and pertinent written comments offered on the anonymous survey were the following: “AHH!! I feel smart because I actually practice a lot before I call.” “It makes me nervous having to record, but I practice a lot to help me get over that.” “I do not do the Google Voice because I don’t want the whole class to hear me.”The final comment clearly referred to my tendency to play recordings for full class feedback — food for thought. Is that a motivating or inhibiting factor? It probably depends on the student.

A student who was frustrated at his performance in Spanish and was beginning to exhibit some anger management issues received the following Spanish translation of a Ralph Waldo Emerson quote via text message through Google Voice: Por cada minuto que estás enojado, pierdes sesenta segundos de felicidad. I did not supply a translation

The access that I had to that student combined with the ease and speed of communication presented by Google Voice solved more than a pronunciation problem; it likely helped me head off a building class management issue by engaging that student on his terms outside of the classroom setting.

“I have a student who hasn’t done any homework this quarter, and out of the blue he sent me a goofy text message to my Google Voice number — completely unrelated to Spanish — something like “I hate this rain”— and, being the nerdy teacher, I texted him immediately back in Spanish: “No me gusta la lluvia tampoco.” One day later, he walks in for the first time with his homework and makes a big production about turning it in. I can’t help but feel that the personal connection of texting helped him remember — and actually want to do — the work for my class.”

Surprisingly, these “irredeemably unreachable” students have proven highly receptive to the notion that their cell phones can and should be used for educational purposes. Figure 2, for example, shows a fairly typical SMS exchange on an oral homework assignment for intermediate level students. While not all students will text back when I supply SMS feedback, those that do, like this one, tend to be looking for specifics and positive reinforcement. How is this additional engagement and interaction bad?

Elite schools have spent vast sums of money on expensive language laboratory hardware and software as an approach to active engagement in the language learning process. They have provided their students with the latest and greatest in computer-assisted (language) learning and computer-mediated communication tools, at considerable cost.

“The way you teach a language is not about grammar; it's about communication skills,” Yan says. “So that face-to-face aspect has to be there…. It should never be done by students checking out a website and doing drills. That is not my idea of an online course.”

But in general Ruth, who teaches Spanish, says he remains wary of where offering online degrees in relatively low-demand languages might lead. “We don’t want this to leak into the areas where real interest lies and where real instructors are,” he says.
