“Head First” and Zig-Zag Learning

While in college, I had a job as a teaching assistant for freshman writing courses. Many students thought they had writer’s block because they were waiting for something to come to them fully formed. They assumed a good writer just wrote, as if taking dictation from an inner voice, start to finish.

My job was to help them understand that writing an essay is not a linear process. The result might look neat and tidy, but you don’t get there in one clean pass. It is a zig-zaggy process of discovery, where writing and thinking—and rewriting and rethinking—lead somewhere you can find only by taking the journey. It is a different type of learning from what most first-year students know, but when it clicks, you can feel a door opening inside.

I tell this story as background to my thoughts on an innovative series of technical how-to books, O’Reilly’s “Head First” series. It presents subjects in terms of how people learn, which is more like the aforementioned zig-zaggy process of discovery than the orderly, linear approach of the traditional tech how-to book.

Accordingly, in the Head First series, redundancy is a feature, not a bug. The authors present key concepts in multiple ways, from different angles. You might get a relatively conventional explanation of an idea in one place. Later, it may reoccur within a dialog, a story, or a visual—or all of the above.

In Head First, visuals are big, especially pictures of people who act out key ideas, raise questions, and otherwise proxy for you, the reader. Head First uses people as props for illustrating ideas, providing more immediacy and emotion than an abstract description can. It’s the social interface, on paper. And it’s not the only way things are presented, just another form of zig-zagging.

Finally, Head First’s writing style is conversational, not didactic—the books talk with you, not at you. And in the name of keeping you engaged, they employ humor and cleverness liberally. Mix it up. Zig and zag.

Although some tech types will regard these titles as O’Reilly’s answer to the “…for Dummies” series, Head First’s mission is more profound. The point is not to dumb-down a topic but rather to make it more learnable without sacrificing the substance of a high-quality intro text.

Remember, the lesson about teaching writing was that writers learn what they’re saying zig-zaggedly. For complex topics, readers learn the same way. The question is whether the media they learn from helps or hinders that.

So, to the people behind the Head First series, congratulations and thanks for moving the ball forward.
