Overview Modeling Instruction Learning Assistant Program Transformed introductory labs
Modeling Instruction Scientists model. Student in Modeling Instruction model. What does this look like? Brewe. (2008). AJP, 76. Brewe. (2010) PRST-PER, 7.
velocity velocity 9 m/s 6 m/s 3 m/s vf vo 1 2 3 4 5 6 tf time time Example: Constructing equations from kinematic graphs • Marta’s ideas: • d = x1-x0 • ∆v = vf-v0/(tf-t0) • Others’ ideas: • a = vf-v0/(tf-t0) or • Slope of v-t graph = vf-v0/(tf-t0)
Example: Discovering the acceleration equation using a graph (1:30) • Marta’s ideas: d = x1-x0 Others’ ideas: a = vf-v0/(tf-t0) • ∆v = vf-v0/(tf-t0) Slope of v-t graph = vf-v0/(tf-t0)
What students do in MI • Coordinate representations (graphs and equations) • Sensemake: strive to understand others’ ideas and connect equations to experiments • Evaluate different interpretations (of ∆v) • Students “publish” their results • See a need to come to a consensus • Coordinate conceptual and quantitative understanding

Beyond knowledge: What do students think about learning physics? Measured with: Colorado Learning Attitudes about Science Survey First positive result in a introductory physics class Brewe, Kramer, O’Brien. (2009). PRST-PER, 5. W.K. Adams, et al. (2006). PRST-PER, 2.
Modeling interview data Before [in other science courses] I would just look for what’s the right answer. How do I get there? I don’t care about the concepts…I just want the answer so I can get the grade. I can actually tell you why an equation is the way that it is, and how it helps, how it works with things. I feel like I can really understand the concepts more… Ana [This class has] superintegrated me into FIU. I cannot imagine dropping out, literally cannot imagine not finishing school… That’s the biggest deal that’s ever happened to me. Marta
Evidence that MI works By learning in a way similar to how scientists learn, we see: • Significantly improved conceptual gains • Increased student success • Positive attitudinal shifts • Improved student engagement
Learning Assistant Model Goal: More high-quality physics teachers Recruit top students to teach in reformed courses • Provide support for reform instruction in labs • LAs experience rewards of teaching and discover teaching is intellectually challenging • Engage science faculty in teacher recruitment and preparation • Transform departmental culture to value research-based teaching as a legitimate activity
Semester in LA Program Student in mostly traditional courses K12 Math /Science Teacher 0 1 2 3 4+ Pre-service teacher experience Teaching Experience Applies to be a Learning Assistant Student in transformed math/science course Learning Assistant Begin taking Education courses Learning Assistant LA Pedagogy Seminar • NSF Noyce • Fellow • Enrolled in math/science ed program Learning about the Teaching Experience
Extending reform: across STEM • Learning Assistant model spans many disciplines in STEM (Science, Technology, Engineering, Mathematics) • LAs model affords various implementations • LA model has grown: 174 LAs during 2008-11
Growth in Learning Assistant Model Goertzen, et. al. (2010). PRST-PER, 7.
Extending reform: FIU’s science teacher preparation • Explicit recruiting model • Identifies top students in introductory science classes • Offers multiple, varied commitment opportunities for teaching • Integrated across Arts & Sciences and Education • Content-area degree plus teaching certification within 120 credit program
Pathway for expanding reform + Research-based curriculum: Open Source Tutorials Impact all introductory physics classes
Open source tutorials Students work in groups of 3-4 • Active-learning worksheets: • PER-based • Epistemologically-focused • Open-source • Includes lab activites Taught by 1 TA and 1-2 LAs
2M M Example: Newton’s third law Tutorial goal: Reconcile Newton’s third law with idea that the car suffers more damage (Work individually) In summary, for most people, Newton’s third law contradicts the common-sense intuition that the car reacts more during the collision. Which one of the following best expresses your attitude toward this contradiction? i. We shouldn’t dwell on these kinds of contradictions and should instead focus on learning exactly when Newton’s third law does and doesn’t apply. ii. There’s probably some way to reconcile common sense with Newton’s third law, though I don’t see how. iii. Although physics usually can be reconciled with common sense, here the contradiction between physics and common sense is so blatant that we have to accept it.
2M M Example: Newton’s third law Suppose the truck’s mass is 2000 kg while the car’s mass is 1000 kg, and suppose the truck slows down by 5 m/s during the collision. Suppose the car and truck remain in contact for 0.50 seconds before bouncing off each other. Calculate the truck’s acceleration during the collision. Students modify their intuition: acceleration is different, but forces are not.
