Educating Machines: The Historical past of Personalised Studying
by Audrey Watters
2021, MIT Press, $34.95; 328 pages.

As reviewed by Michael B. Horn

For practically a decade, Audrey Watters has solid herself as a snarky and skeptical author about training expertise. From theories of customized studying to new education-technology corporations, Watters makes an attempt to chop down the hype and to sprint hopes.

In her writings, she often covers the historical past of training, and argues that most of the concepts behind training expertise and innovation are neither new nor good.

Her new guide, Educating Machines: The Historical past of Personalised Studying, rests on these two pillars. The guide presents two compelling microhistories of instructing machines sandwiched between a preface and a conclusion that try unsuccessfully to make use of these histories to contextualize—and solid doubt upon—customized studying and right now’s efforts to deploy new expertise in that effort. Her large objection to customized studying and training expertise is that the 2 inevitably entail a crude behaviorist strategy to instruction that deprives college students and academics of freedom.

Though the instructing machine is most related to Harvard psychology professor B. F. Skinner, Watters takes the reader again to the period of President Calvin Coolidge and Ohio State Professor Sidney Pressey’s efforts to construct and commercialize an “Computerized Instructor”—a machine that will permit college students to reply questions, obtain suggestions, and, on the change of a lever, progress solely after they appropriately answered the query.

Pressey’s background was within the area of standardized intelligence testing, which had turn out to be well-liked on the time. Though he knew a lot about standardized exams and textbooks, “the manufacturing of a bit of scientific gear was one thing fairly completely different,” Watters writes.

Watters presents a prolonged description of Pressey’s foibles and frustrations in commercializing his invention. It’s a historical past that foreshadows Skinner’s expertise, and Watters makes certain the reader doesn’t miss the echoes by mentioning that would-be innovators resembling Skinner ignored the previous and appeared to imagine that, in Watters’s phrases, “Certainly this time, issues could be completely different.”

Certainly, Skinner’s dramatic and futile efforts to commercialize a instructing machine weren’t a lot completely different from Pressey’s. Watters captures the whole lot from Skinner’s behaviorist philosophy to his tone-deaf dealings with former Harvard President James Bryant Conant, as he tries to persuade Conant that his instructing machine will repair American training within the wake of Sputnik. Readers additionally be taught of Skinner’s emotional and extremely erratic dealings with the Rheem Manufacturing Firm, with which he had signed an settlement to provide his machine.

B. F. Skinner taught pigeons to play ping-pong using “operant conditioning.” His teaching box pioneered methods now used in computer-aided instruction.
B. F. Skinner taught pigeons to play ping-pong utilizing “operant conditioning.” His instructing field pioneered strategies now utilized in computer-aided instruction.

At occasions the narrative delves too deeply, in my estimation, into the trivialities and particulars of main sources. But total, Watters makes use of these sources effectively, and her sharp writing propels the story ahead.

What Watters paints finally is much less a narrative of Skinner’s machine failing within the business market for academic causes and extra a story of flawed enterprise fashions and missteps in manufacturing.

This distinction is on the root of the guide’s issues, which begin with its subtitle, “The Historical past of Personalised Studying.” A guide that totally lined this subject would focus not simply on the historical past of the instructing machine—one thing extra training innovators would do effectively to know—but in addition on many different customized methods and approaches, from tutoring to Montessori training. Watters does helpfully clarify why she doesn’t sort out computer-based and on-line training and retains her main give attention to the period of instructing machines, however equating the motion to personalize studying with machine expertise is reductionist.

The historical past that Watters presents is stable, however her commentary round it’s at occasions flawed. As an illustration, she misunderstands why many individuals name conventional colleges the “manufacturing facility mannequin” of training. Sure, most of the options of American training that critics usually examine to factories have been in reality imported from the Prussian training system. Nevertheless, as David Tyack and Larry Cuban show of their timeless quantity Tinkering Towards Utopia, the push to include standardized testing into American colleges and the usage of Frederick Winslow Taylor’s ideas of scientific administration there have been clearly impressed by America’s factories, which themselves have been seen as the newest in expertise. Watters acknowledges this motion however nonetheless castigates those that would name them factory-model colleges.

What’s extra, her intensive dialogue of behaviorism might use extra grounding, as her analogies break down in a number of locations. Considered one of her critiques of behaviorism is that it doesn’t work effectively. But she writes about how these methods are used at Google to create personalization for people. It’s arduous to argue that Google hasn’t been profitable on this pursuit. So if personalization works within the realm of the buyer web, as at Google, and if that success relies no less than partly on behaviorism, then this may recommend that behaviorism works—which is at odds with a part of the story Watters tries to inform.

She would nonetheless argue that this type of personalization primarily based on behaviorism is dangerous as a result of it limits freedom, however analysis on creativity means that with a view to be inventive, one should first construct information and perceive the principles of a website earlier than one can start usefully breaking guidelines—significantly in adjoining or orthogonal fields. That might recommend, then, that behaviorism, whereas not an entire training idea, would serve sure studying functions resembling constructing information. This, in flip, would permit for the usage of expertise like important considering and creativity.

With that mentioned, there are important causes to doubt the direct transferability of behaviorism to training from the buyer web world—which renders a few of Watters’s analogies much less helpful. Nudges, for instance, have a blended monitor document in training (see “Nudging and Shoving College students Towards Success,” options, Spring 2021). Civitas Studying, a student-success firm primarily based on predictive analytics that Watters references, has largely failed, as a result of its algorithm struggled to be helpful because it scaled. No less than one problem with utilizing synthetic intelligence in training is that any errors an algorithm makes can derail a pupil’s studying and self-efficacy, whereas on the buyer web a mistaken advice from Amazon or Netflix has little draw back, no less than for a person buyer. However these aren’t the challenges that Watters raises. Certainly, her dislike of behaviorism due to its limits on freedom leads her to recast Seymour Papert, generally known as a pioneer of constructionist studying, as a behaviorist.

This implies that Watters is primarily simply ranting in opposition to the usage of any and all digital training expertise. That type of protest appears akin to sitting on high of a shifting prepare and yelling cease.

Watters doesn’t get into the subject of how a number of the opponents to Skinner’s instructing machine have fared. Actually, a few of right now’s applied sciences that she belittles have seen large adoption. Khan Academy, a foil she writes about within the guide, has over 100 million customers—in dramatic distinction to Skinner’s expertise. Age of Studying, the maker of the favored ABCmouse app and web site, serves greater than 50 million kids. Certainly, the digitization of America’s education curriculum is effectively underway and has possible accelerated because the pandemic. Even longtime training publishers like McGraw-Hill, for instance, are majority digital, not print, corporations now. Whether or not they’re efficiently personalizing studying is a distinct query.

In her conclusion, Watters writes that the adoption of expertise in training has ebbed and flowed over time; it’s “not a short-lived fad however reasonably a recurring pattern.” This portion of the guide is, in some ways, an announcement of her skilled profession as a critic protesting expertise as a detriment to people’ freedom. Watters cites the Freedom Faculties that arose from the 1964 civil-rights undertaking Freedom Summer time as “a community of different training facilities that supplied the sort of instructing and studying that the general public faculty system of Mississippi had refused to offer its Black inhabitants.” She goes on to say, “If we reject instructing machines and applied sciences of behavioral management in training, we definitely received’t be the primary to take action. . . . From the historical past of refusal, we will see when college students and academics and communities protested makes an attempt to engineer them, into both enlightenment or submission. From the alternate options they imagined and constructed—most notably, maybe, the Freedom Faculties, we will glean methods to assemble and share information that depend upon people reasonably than machines, liberating us from the environment friendly management of the ‘Skinner field.’ These practices privilege the a lot messier types of instructing and studying, types which might be essentially grounded in freedom and dignity.”

It’s all fascinating historical past. However opposite to the writer’s competition, the historic examples cease effectively in need of demonstrating that right now’s progressive practices will impede freedom reasonably than advancing it.
