Teaching Machines

What is this book about?

Watters is among the sharpest critics of education technology. She excavates forgotten archives: the teaching machines built by psychologist Sidney Pressey in the 1920s, Skinner's behaviorist programmed instruction, the programmed textbooks of the 1960s, and how each declaration that 'technology will transform education' rose, failed, and reappeared under a new name. The book is not opposed to technology; it lets you see the historical baggage and repeatedly unmet promises carried by the slogan 'personalized learning'.

Why read it?

When AI education products once again promise 'personalized learning', you need a book that recognizes the pattern. Watters shows that nearly every current claim has a 1920s ancestor, and that the reasons for failure are strikingly similar: underestimating the complexity of teaching, overestimating the reach of automation. This is the most practical inoculation available.

Core Ideas

• The history of education technology is a repeating cycle rather than steady progress.
• 'Personalized learning' often means reducing teaching to measurable behavioral training.
• Technological promises usually fail not because the technology is inadequate but because educational aims were simplified.
• Understanding the history of failure improves judgment more than studying success stories.

What questions does this book try to answer?

• Why does each generation of education technology repeat the previous generation's promises?
• Does 'personalized' mean adapting to the learner, or breaking the learner into data points?
• What historical questions should one ask when evaluating an AI education product?

Who should read it?

For education-technology practitioners, investors in the sector, school administrators, and parents. The stance is pointed; balance it by reading the advocates as well.

How to Read It

Focus on the chapters on Pressey and Skinner, the origin of the cycle, then the closing chapters on contemporary 'personalized learning' to see the same rhetoric reused. List the keywords of each era's promise as you read; you will find they are nearly interchangeable.
