Heuristics: A Love Story



(Throughout this post, I reference the book Get It Done! Writing and Analyzing Informational Texts to Make Things Happen by Jeffrey D. Wilhelm, Michael W. Smith, and James E. Fredericksen. The book is well worth the read)

I learned a new word this summer: heuristic. I first encountered it while listening to Dr. Zalman Usiskin, professor of math education at the University of Chicago, as he spoke at MTSU on Critical Thinking With the Common Core.

Zal spoke about the different types of understanding present in math, using the acronym SPUR—Skill/algorithm, Property/proof, Use/application, and Metaphor/analogy. He commented that working on skill/algorithm in isolation from the other types of understanding is harmful to students’ mathematical development. For a practical example, if students know the steps for borrowing when doing multi-digit subtraction, that is an algorithm, a formula, a skill they can practice. However, just because they can follow the steps does not mean they have full understanding of base ten operations. Do they understand that the tens digit is ten ones? Can they create a model using manipulatives? Do they connect that these activities required the same math concept? If you have only taught them the skill, you have not given them true understanding, nor have you equipped to tackle the future problems they will encounter.

Now I’m not a math teacher, which is why I chose a second grade math skill in my practical example. I am a language teacher. But this concept of different types of understanding struck a chord with me. In the past, writing instruction has been algorithm based, particularly for students who are labeled “at risk”. Writing lessons go something like this:  “This is the structure of the 5th (or 8th or 11th) grade writing prompt, and here is the algorithm you will follow to get a good score.” Critics call it “formulaic” writing. It is how I was taught to write in my English classes, with the 5-paragraph essay: introduction, 3 supporting paragraphs, and conclusion. But this kind of writing is largely artificial and doesn’t have many real world applications. It prepares students for “the test” but not the day after graduation.

The point in Zal’s presentation that ignited my thinking was when he began discussing the difference between problem and exercise. “A problem,” he said, “is an exercise for which you have no algorithm.” He went on to say that rather than giving students repeated algorithms to practice, we want to give them problems and support them with heuristics that empower them to discover the algorithms themselves.

I fell head over heels in love with the new word heuristic. I didn’t know what it was, but I sure wanted to find out. Even though I don’t teach math, I wanted to make certain that my students knew how to solve real world problems, not just prepare for a test.

The next week I came to MTWP Advanced Institute on Common Core, and lo and behold, again I encounter my new crush, heuristic, in Wilhem, Smith, and Fredericksen’s Get It Done! Writing and Analyzing Informational Texts to Make Things Happen. Here’s an excerpt from Chapter 3:

The word heuristic comes from the Greek word eureka, which means I discover (remember Archimedes in his bathtub?). It is defined as “experienced-based techniques for problem solving, learning, and discovery” (Wikipedia, retrieved 8/18/2011) or “a generative process that enables a person to discover or learn something for herself” (Merriam-Webster online dictionary, retrieved 8/18/2011). Heuristics, in short, are flexible problem-solving tools based on generative underlying principles. Because they are based on generative principles, they can be developed, tweaked, and transformed, and then transferred to new situations. (In a sense, (CCSS) reading anchor standards 1-9 and writing anchor standards 1-9 are a heuristic for accomplishing anchor standard 10 in each area.)

At this point my crush on heuristics became complete and total infatuation. You see, I am a constructivist at heart. My philosophy has always been that the responsibility of a teacher is to set up an environment that enables discovery. But the reality of making this work has been less than ideal, particularly because my responsibility is to students who are “at-risk.” My job is to get them on grade level as quickly as possible, which means I felt pressure to give it to them as directly as possible. In math terms, teaching them the algorithm of writing was a lot easier than fleshing out all possible understandings of the concepts. Attempts at workshop style teaching felt too chaotic. I needed more structure. Now, this new love in my life, heuristics, is providing a structure. But that structure is flexible and generative and adaptable, (in contrast to algorithm’s rigid and narrow focus) which means it is meaningful to real life,

This love has walked into my life at just the right season of change. I am moving to a new classroom, have a new schedule with 60 minutes (!) of instructional time for each group, and am working under the Common Core State Standards, which by definition are designed to prepare students for college and career, not just the standardized test. The CCSS give equal attention to reading and writing, emphasize critical thinking skills and problem solving, and are broad enough to ensure deep understanding. Teachers will no longer be able to simply “cover” standards with a simple pacing guide. They will have to address multiple standards in each unit, cycling back through them to deepen student understanding. The PARCC assessment my students will be taking in the future is a complex assessment that (hopefully) eludes formulaic response. I now have an excuse to teach the way I have wanted to since the beginning of my career!

I am going to begin with a focus on one group, as to not overwhelm myself. My 6th grade students are the group for which I have no curriculum to follow, so I am creating a curriculum based on the heuristic model presented by Wilhelm et al. Using the topic of poverty as an umbrella, we will go through 8 units, each one focused on an essential question surrounding poverty, a type of thinking, and an end product that has real world applications. For each unit, we will work through the declarative and procedural knowledge of the substance (poverty and product) and the form (type of thinking), as well as the transferal of knowledge to other real world scenarios.  

I am going to structure my class around inquiry, as defined by Wilhelm “the rigorous apprenticeship of learners into the processes of expert reading, composing, and working in specific disciplines.” (pg. 119 of Get It Done)

On a daily basis, we will begin with 10-15 minutes word study and language practice, follow with a 20-25 minute reading workshop, and then connect that reading with 20-30 minutes of “composing” workshop in response to reading. (I say composing rather than writing because our work will be multi-modal—it may require visual, dramatic, oral, written, or media oriented response. For more information on writing vs. composing check out pg. 37-38 of Get It Done).

Within each 4-week unit, I will scaffold instruction so that students experience gradual release of responsibility for the knowledge substance and form I am focusing on. In order to do that, we will move in the directions recommended by Wilhelm et al (pg. 41).

-From familiar to less familiar
-From short to long
-From oral to written
-From multimodal to print
-From concrete to abstract
-From social to individual
-From scaffolded to independent

For example, in Unit 1 we are focusing on the heuristic of naming and listing, which is foundational for all the other thinking skills in future units. We will begin in whole group (social) by looking for familiar, real world examples of lists: grocery lists, menus, wills, contacts in your cell phone, etc. Then we will move to the less familiar academic forms of lists: table of contents, index, items in a series, use of colons, etc. In writing, they will begin by generating lists about themselves and their preferences, and then will move to lists that support our end product, which is a web-based guide for parents of future Hobgood students about what children need to survive and thrive before age 5. Because this product is the first one of the year, it will be a group project (with individual responsibilities), and it will be multimodal rather than print. By the end of the year, students will be writing individual formal multi-paragraph essays.

I invite you to join me as I continue my courtship with heuristics throughout the year. Here is the link to the folder on my Google drive so that you can view my work in progress. Comments, questions, and suggestions are welcome! I’ll also be posting reflections as I implement this curriculum, so come back to learn more about the good, the bad, and the ugly as I attempt to make my philosophical ideal a reality.
