As I recently wrote in Don’t Teach Them Facts – Let Student Discover Patterns 

It’s unfortunate that student don’t get to use their innate perceptual skills more often in the classroom. Instead of discovering patterns on their own, students are “taught” to memorize patterns developed by someone else. Rather than do the messy work of having to figure out what’s going on, students are saddled with graphic organizers which take all the thinking out of the exercise. 

"Doodling in Math Class: Spirals, Fibonacci, and Being a Plant" captures the fascination of patterns in nature. Discover more patterns from Vi Hart - Mathemusician

Let’s stop acting like hollowed-out zombies, with BlackBerrys and iPhones replacing eye contact, handshakes and face-to-face conversations. It’s time to live once again in the present and simply be where we are.

Testing or Teachable Moments?

Several years ago, after I brought in tulips from my garden, my fifth-grade students wanted to plant their own. I learned that few students in my school’s high-poverty community had ever planted anything, so we planted tulips (not in the curriculum). In the process, one student found part of a rusted horseshoe, so we studied the history of the neighborhood (not in the curriculum), discovering that a farm had existed there 90 years earlier. Then, because of the proliferation of questions about the artifacts we’d unearthed, we studied archaeology (not in the curriculum). With the new push for common core standards nationwide, perhaps no student in any fifth grade in the United States will plant tulips, explore the history of his or her neighborhood or learn about archaeology ever again.

Black Friday: Will Teachers Be Shopping or Working at the Mall?

Statistics show that nearly half of all teachers leave within the first five years. Low salaries and high stress are among the top reasons teachers “burnout” and quit the profession. Sixty-two percent of our nation’s teachers have second jobs outside of the classroom. What’s your kid’s teacher doing tonight – home working on lesson plans, or selling cell phones at the mall?

American Teacher is a film that follows four teachers who struggle to make ends meet while trying to stay in the profession they love. With narration by Matt Damon, it tells their stories through a mixture of footage and interviews with students, families, and colleagues, as well as the teachers themselves. By following these teachers as they reach different milestones in their careers, it uncovers a deeper story of the teaching profession in America today. This post features a trailer and information about screenings in your area.

Why I Teach? A Voice from StoryCorps

It’s not an best of time for teachers – budget cuts, layoffs, increased class size, test-score based evaluations, and attacks on collective bargaining / tenure, etc. Meanwhile, the self-appointed corporate reformers would have you believe that they can fix education with a strong dose of market incentives. This morning I heard a moving StoryCorps narrative on why one young man chose to become a teacher. Spoiler alert – it wasn’t merit pay.

Why Johnny Can’t Search – a Response

Clive Thompson wonders “Why Johnny Can’t Search” (Wired Magazine Nov, 2011). I note that schools contribute to the problem in two ways. In an effort to protect students from offensive online content many schools respond by sequestering students behind an information firewall. That sets Johnny up to fail in our “wild west” of information. Every day he walks into a sanitized information landscape with the expectation that anything he finds behind the school firewall is acceptable.

Schools inhibit the development of critical evaluation skills in another way – the relentless (test prep) focus on mastery of facts. Johnny can assess the validity of information because he’s awash in a sea of text without context. Critically evaluating sources requires a deeper understanding of author and purpose. That’s developed with an inquiry-based approach to learning. No time for that – we have to “cover” content for the test. In the relentless march to the exam, Johnny gets well acclimated to quickly stuffing his head with facts. No wonder he’s willing to take up Google on the bet that “I’m Feeling Lucky.”

Solve the Problem

The key to solving this problem is finding a pattern. That’s a very human skill. Even newborns can soon recognize faces. As Jon Medina has said “We…are terrific pattern matchers, constantly assessing our environment for similarities, and we tend to remember things if we think we have seen them before.”

It’s a pity we don’t do a better job of teaching pattern recognition in school. Uncovering an underlying pattern is essential to constructing meaning. In school we typically “teach” patterns to students as “facts,” rather than ask students to discover the pattern for themselves. Of course this strips the activity of its real value as a learning strategy, and turns into just another thing to memorize. Asking students to file some pre-selected information into a graphic organizer isn’t analysis – it’s just moving stuff around. True analysis involves doing the challenging work of trying to make sense of information.

Enough commentary, have you solved the problem yet?

Dilbert’s Seven Arguments for PBL

The first thing you should learn in a course on entrepreneurship is how to make yourself valuable. It’s unlikely that any average student can develop a world-class skill in one particular area. But it’s easy to learn how to do several different things fairly well. I succeeded as a cartoonist with negligible art talent, some basic writing skills, an ordinary sense of humor and a bit of experience in the business world. The “Dilbert” comic is a combination of all four skills. The world has plenty of better artists, smarter writers, funnier humorists and more experienced business people. The rare part is that each of those modest skills is collected in one person. That’s how value is created.

When it came to time to study the debate over the ratification of the constitution, my students didn’t have to ask the question – “why do we need to study this?” They realized that they were looking at “Round 1″ of an ongoing debate over how strong the central government should be.

Teachers, Have the Courage to be Less Helpful

» 19 July 2011 » In Commentary, Strategies, Teachers » 13 Comments

Most of our students get a steady diet of force-fed information and test taking strategies. We’re giving a generation of kids practice for predictable, routine procedures. Here’s thoughts on how you can begin to “be less helpful” and give students practice in “figuring it out” for themselves. That’s where the real learning will take place.
