A discussion about inquiry-based learning (part 1)

In many mathematics classrooms, "doing mathematics" means following the rules dictated by the teacher, and "knowing mathematics" means remembering and applying these rules. However, an inquiry-based-learning (IBL) approach challenges students to create/discover mathematics. Boiled down to its essence, IBL is a method of teaching that engages students in sense-making activities. Rather than showing facts or a clear, smooth path to a solution, the instructor guides students via well-crafted problems through an adventure in mathematical discovery. In this talk, we will address the following questions: What is IBL? Why use IBL? What are some of the challenges of IBL? How can you incorporate more IBL into the classes that you teach? In addition, I will relay my personal experience and discuss how I came to IBL and where I plan to go with it. Time permitting, we will also discuss a few different examples of what an IBL classroom might look like in practice.

This talk was given at the NAU Department of Mathematics and Statistics Teaching Showcase on Wednesday, November 19, 2014.

9. the big picture Claims ∙ An education must prepare a student to ask and explore questions in contexts that do not yet exist. That is, we need individuals capable of tackling problems they have never encountered and to ask questions no one has yet thought of. ∙ If we really want students to be independent, inquisitive, & persistent, then we need to provide them with the means to acquire these skills. Lofty Goals ∙ Transition students from consumers to producers! ∙ I want to provide the opportunity for a transformative experience. ∙ I want to change my students’ lives! 8
10. what is ibl?
11. what is inquiry-based learning? ∙ According to the Academy of Inquiry-Based Learning: ∙ IBL is a teaching method that engages students in sense-making activities. ∙ Students are given tasks requiring them to solve problems, conjecture, experiment, explore, create, & communicate. ∙ Rather than showing facts and/or algorithms, the instructor guides students via well-crafted problems. ∙ Often involves very little lecturing, and typically involves student presentations. ∙ Example: Moore Method, after R.L. Moore. ∙ Students should as much as possible be responsible for: ∙ Guiding the acquisition of knowledge, ∙ Validating the ideas presented (i.e., students should not be looking to the instructor as the sole authority). 10
12. what is ibl? Guiding Principle of IBL Continually ask yourself the following question: Where do I draw the line between content I must impart to my stu- dents versus content they can produce independently? Where do I draw the line between content I must impart to my stu- dents versus content they can produce independently? Two Typical Approaches/Modes to IBL ∙ Student presentations. ∙ Small group work. Most IBL instructors implement some combination. Where do I draw the line between content I must impart to my stu- dents versus content they can produce independently? 11
13. what is ibl? Important Role Changes ∙ Instructor becomes a mentor, cheerleader, and coach. Focus on teaching process. ∙ Student becomes the mathematician. IBL vs Presentations/Group Work ∙ Student presentations & group work act as vehicles for IBL. ∙ Yet student presentations & group do not imply IBL. ∙ What matters is what is happening during these activities. 12
14. what is ibl? My version of IBL ∙ 5-10 “tasks” assigned each class meeting (Daily HW). Due next class. ∙ Students responsible for digesting new material out of class. ∙ Nearly all class time devoted to students presenting proposed solutions/proofs to Daily HW. ∙ My job: ∙ Facilitate/manage ∙ Mr. Super Positive ∙ William Wallace meets Robin Williams ∙ Students may request mini-lectures. ← Hang on every word! ∙ Each week, students submit a subset of problems similar or identical to problems from the previous week (Weekly HW). Graded harshly. 13
15. what is ibl? Are you doing IBL? ∙ Who develops the mathematics that is discussed? ∙ Who presents the mathematics? ∙ Who critiques the mathematics that is presented? ∙ Who decides what is correct mathematics? ∙ Who asks the questions that drive further work? 14
16. why ibl?
17. why ibl? My IBL origins ∙ Number of IBL classes as student: 0 ∙ When I started teaching, I mimicked experiences I had as a student (I lectured). ∙ By most metrics, I was an excellent instructor. But: “Things my students claim that I taught them masterfully, they don’t know.” — Dylan Retsek “Things my students claim that I taught them masterfully, they don’t know.” — Dylan Retsek ∙ First exposed to IBL/Moore Method during a Project NExT workshop run by Carol Schumacher (Kenyon College). ∙ Taught 1st full-blown IBL class in Fall 2009. ∙ To date taught using various forms of IBL over a dozen times. ∙ Currently Special Projects Coordinator for AIBL & mentor for new IBL practitioners. “Things my students claim that I taught them masterfully, they don’t know.” — Dylan Retsek 16
18. why ibl? Some Data ∙ 4-5 million freshmen in HS. ∙ 75% HS graduation rate. ∙ 1.2 million bachelors degrees annually (< 1% of BA/BS are in math). ∙ 48,000 doctoral degrees annually (400–500 PhDs in math). Conclusion? Education is a self-populating institution! You are peculiar! You are peculiar! We need to renormalize. You are peculiar! 17
19. why ibl? What is happening in STEM education? ∙ There exists a growing body of evidence suggesting students are dissatisfied with learning experiences in STEM. ∙ Math education research suggests that college students have difficulty with: ∙ Solving non-routine problems, ∙ Packing/Unpacking mathematical statements, ∙ Proof. Schoenfeld 1988, Muis 2004, Selden and Selden 1995/1999/2003, Dreyfus 2001, Sowder and Harel 2003, Weber 2001/2003, Weber and Alcock 2004, Tall 1994 18
20. why ibl? The Good News Evidence from the math ed literature suggests that active, learner-centered instruction leads to improved conceptual understanding, problem solving, proof writing, retention, habits of mind, and attitudes about math. Boaler 1998, Kwon et al. 2005, Rassmussen et al. 2006, Smith 2006, Chappell 2006, Larsen et al. 2011/2013/2014, etc. 19
21. why ibl? The Colorado Study by Sandra Laursen et al. ∙ 300 hours of classroom observation, 1100 surveys, 110 interviews, 220 tests, and 3200 academic transcripts, gathered from > 100 course sections at 4 campuses over 2 years. ∙ Statistically significant advantages for students in IBL vs traditional courses. The Twin Pillars ∙ Deep engagement in rich mathematics, ∙ Opportunities to collaborate. 20
22. why ibl? Laursen et al. 2013 “Our study indicates that the benefits of active learning experiences may be lasting and significant for some student groups, with no harm done to others. Importantly, ‘covering’ less material in inquiry-based sections had no negative effect on students’ later performance in the major.” Laursen et al. 2014 “Despite variation in how IBL was implemented, student outcomes are improved in IBL courses relative to traditionally taught courses, as assessed by general measures that apply across course types. Particularly striking, the use of IBL eliminates a sizable gender gap that disfavors women students in lecture-based courses.” 21
23. personal reflections
24. personal reflections My overall point of view ∙ I’m hooked. For most students, the net overall gain beats out lecturing. ∙ IBL is not a magic bullet. ∙ IBL is a lot of work, but to me it is worth it. ∙ Implementing IBL requires patience, flexibility, and regular refinements. ∙ One reason IBL works: Mode of engagement is different when listening to expert vs novice. ∙ With the right set of materials, content coverage is not really an issue (my IBL notes for Abstract Algebra need some work in regards to coverage.) 23
25. personal reflections Personal Obstacles ∙ If I lecture, then I dictate pace. ∙ I enjoy lecturing! ∙ If I write something on the board, then there is a good chance that it will be done correctly. ∙ Keeping my mouth shut is hard. CONTROL! CONTROL! Personal Concerns ∙ I think it would be a shame if students never had the opportunity to meditate on some of the classic mathematics texts (e.g., Rudin, Gallian). ∙ There is such a thing as too much collaboration. CONTROL! 24
26. personal reflections Keeping my mouth shut…and assessing ∙ If I spend 50 minutes talking, it’s unlikely I’ve done any assessment. ∙ During a typical day in an IBL course, the whole class session is spent on assessment. ∙ When I used to predominately lecture, I was really just guessing at how effective I was being. Students lulled into thinking they understood. ∙ Students presenting, discussing, & collaborating provides me & them with immediate feedback about how things are going. 25
27. personal reflections IBL is messy (and that’s ok) ∙ In an IBL class there are lots of issues that bubble to the surface that we blissfully ignore when lecturing. ∙ More day-to-day differences between IBL classes. I usually have no idea what will happen each day! ∙ We are responding to what the students are doing & thinking, & there are natural & necessary ups & downs. ∙ Some IBL class sessions look rougher than others because students are in the process of learning difficult things. #PF ∙ In contrast, in a lecture class, we control everything that happens at every instant. This can look lovely to an observer but buries most of the messiness. IBL is jazz! 26
28. personal reflections Reflections on current courses ∙ MAT 136: Calculus 1 ∙ MAT 320: Foundations of Mathematics ∙ MAT 411: Abstract Algebra 27
29. personal reflections Keys to Success ∙ Effective marketing ∙ Return to your guiding principle ∙ Adjusting problems/tasks appropriately ∙ Patience & trust! ∙ Community ∙ Build on positive experiences ∙ Pick a style that you are comfortable with ∙ Adapt, overcome, & improvise 28
30. personal reflections Marketing! ∙ Students are asked to solve problems they do not know the answers to, to take risks, to make mistakes, & to engage in #PF. ∙ Students need to know that it is ok to be stuck & that you will support them in this endeavor. ∙ Students need to know what their role is & what the instructor’s role is. ∙ Expectations & goals need to be reiterated throughout the course. 29
