Integrating TOK Across the Curriculum - A Place to Begin
|
Last week, Sofía and I had an incredibly enjoyable conversation with Sara Ross and Andrew Magness, who lead the Middle Years and Diploma Programmes at Valley High School in Las Vegas, Nevada. It was an absolutely fantastic conversation about the power and impact of an IB education. We came away inspired by their work, their dedication to their students, their passion to change young people's lives, and excited to work with them going forward, The topic of our conversation was how to most effectively integrate Theory of Knowledge (TOK) across their curriculum and what steps they could take this year with their IB Faculty. Doing this effectively is a challenge at every IB School. But our conversation also reinforced something that I think can make the challenge feel a whole lot more manageable. When it comes to integrating TOK into the IB classroom, you have to find a place to start. Because ultimately, TOK integration is not about importing TOK content into other IB courses. It is about understanding what TOK is actually trying to do. At its core, TOK pushes students up what we call the Ladder of Cognitive Skills (Recall, Describe, Apply, Analyze, Evaluate, Create) in order to succeed on the two TOK assessments, the Exhibition and the Essay. But that same ladder exists in every IB classroom. Students in Mathematics, Biology, History, Economics, Theatre, Literature, and every other IB course are also being asked to move beyond recall and description toward application, analysis, evaluation, and creation. And I think that is one of the most important places to begin. The first step in integrating TOK into the IB classroom is simply recognizing that the skills students need to succeed in TOK and the skills they need to succeed in every other IB course are remarkably similar. What TOK provides is a platform, an environment where those skills can be practiced, challenged, and honed in a much more deliberate and systematic way. And ultimately, that is what meaningful TOK integration can become: Creating common thought patterns across the curriculum so that students are repeatedly pushed toward the higher levels of cognitive skill, especially toward analysis, evaluation, and creation of new ideas. And that conversation made me think it might be worth bringing something back to the surface that we spent quite a bit of time writing about last semester. Because this is not simply a nice idea or something that schools might choose to do. It is an explicit expectation of the IB. In fact, the expectation is stated pretty clearly: “The school provides opportunities for teachers to use collaborative planning and reflection to integrate theory of knowledge into each subject.” Into each subject. That sounds great, but... Let's think about what we are actually asking teachers to do. At first glance that expectation can feel as if we are asking a Biology teacher, a Mathematics teacher, a History teacher, an Economics teacher, a Physics teacher, or a Language teacher to somehow integrate ideas from another course into their own classroom. And in many cases, that teacher has never taught Theory of Knowledge. Imagine being asked to integrate concepts from Music into your Mathematics classroom without ever having taught Music. Or being asked to integrate Economics into Biology without having studied or taught Economics. You would probably need someone to explain what exactly you were supposed to integrate. And I think this gets at one of the interesting realities of working within the IB. The IB is generally very clear about what we are expected to do and what schools will ultimately be held accountable for. But there is often considerably more professional freedom around how we actually do it. And I actually think that is a good thing. Because this is where the creativity of teaching begins. There probably shouldn't be one prescribed formula for integrating TOK into every Biology, Mathematics, Economics, History, Theatre, or Language classroom around the world. But there does need to be some shared understanding of what TOK actually is and what it is asking students to do. And that is where I think school leadership matters. As the year begins, perhaps one worthwhile goal for IB Coordinators, IB Core leaders, and school leaders is simply to identify one thoughtful and purposeful way to help your faculty better understand what happens inside the TOK classroom. Not to turn every IB teacher into a TOK teacher. Not to add another enormous initiative to everyone's plate. Just to begin building enough shared understanding that teachers can recognize where natural connections already exist within their own disciplines and begin making those connections intentionally. This has actually become one of the areas of our work that we are most excited about this year. We are beginning to work with schools and faculties on exactly this challenge: What does meaningful TOK integration actually look like across an IB Programme? And to help with that, I thought it might be useful to put something together that I wish existed when I first started teaching in the IB. Last semester, Sofía and I wrote an eight-part series designed specifically to help non-TOK teachers understand the essential elements of the TOK course. So here they are, all together in one place: The Eight Essential Elements of Theory of KnowledgePart 1: What Is Knowledge? We begin with the most fundamental question in TOK and explore what we actually mean when we say that we “know” something. Here's the link to read further. Part 2: What Are Knowledge Questions? Knowledge Questions are at the heart of TOK, and understanding how they work is one of the easiest ways to begin bringing TOK thinking into another subject. Here's the link to read further. Part 3: Knowledge and the Knower + Five Optional Themes The TOK themes help students examine how knowledge is shaped by identity, culture, technology, politics, religion, and the societies in which we live. Here's the link to read further. Part 4: The Five Areas of Knowledge The Areas of Knowledge explore how knowledge is produced and understood differently across disciplines such as the sciences, mathematics, history, the arts, and the human sciences. Here's the link to read further. Part 5: The Knowledge Framework The Knowledge Framework gives teachers and students a practical structure for examining how knowledge works within any particular discipline. Here's the link to read further. Part 6: The Twelve Concepts These twelve concepts provide some of the simplest and most natural entry points for bringing TOK thinking into everyday subject-area teaching. Here's the link to read further. Part 7: The TOK Exhibition The Exhibition asks students to connect TOK ideas to real-world objects and situations, making knowledge visible, concrete, and personal. Here's the link to read further. Part 8: The TOK Essay The TOK Essay asks students to examine and evaluate complex questions about knowledge across different Areas of Knowledge. Here's the link to read further. You certainly don't need to read all eight at once. But perhaps pick one. Share one with your faculty. Talk about one during a department meeting or professional learning community. Find a place to start. And slowly, over time, we might begin to make this idea of integrating TOK across the curriculum feel a little less abstract and a whole lot more possible. I hope that was helpful See you next week.
