1. Improving on the Recitation Section: Tutorials in Introductory Physics Wed Brown Bag SJP Fa '05

2. What are Tutorials? Research-based Student-centered “Elicit-confront-resolve” Process (discussion, consensus) + Sense-making

3. The Tutorial space (basement, across from Jerry Leigh)

4. Tutorials at CU Used in 1110 & 1120, twice each (+ 1120, now) Part of successful courses => motivation to continue Today: some data Continue support?

5. Resources Space, material, training, personnel Ongoing support necessary. “Learning Assistants” (LA’s) - undergrad STEM majors (interested in teaching)

7. pre/post measures Phys 1110: FMCE Phys 1120: BEMA common exam questions formal + informal survey questions

8. Phys 1110: Distinguishing features 1: “Tut” (Sp04) Tutorials + CAPA 2: “Workbook” (Fa04) Small groups/Knight (+ Mastering Physics) 3: “(More) Trad” (Sp05) Mostly traditional recit’s (Otherwise much like "2" above) (different instructors, semesters …)

9. 1110 summary - up front! Tutorial courses : strongest results on learning gains and attitude surveys Middle course (“2”) (research-based text and hw, clickers + small-group recitations, not Tutorials): good results. Last course (like “2” except recitations): gains solid, lowest of three.

10. Phys 1110 Pretest FMCE (Force and Motion concept evaluation) A nationally validated conceptual exam, like the FCI (but harder) Matched, valid data only. (Eliminate pre>93%) Ave Pre ave = 28%(1) / 34%(2) / 28%(3) Spring (2) higher (fall term)

11. Phys 1110 Posttest Ave Post ave = 74%(1) / 69%(2) / 58%(3)

12. Phys 1110 normalized gains gain(1)=.66 +/-.02

13. Phys 1110 normalized gains gain(1)=.66 +/-.02 g(2)=.585 +/-.02 7.5 points lower => (more than half a letter grade)

14. Phys 1110 normalized gains gain(1)=.66 +/-.02 g(2)=.585 +/-.02 g(3)=.45 +/-.02 (trad recit.) => significantly lower gains. (still, double nat’l standards!)

15. Impact on different pretest populations: "low starters" pretest <=12.5% (% of class in this pool) Course (1) (2) (3)

16. Impact on different pretest populations: "high starters" 50<pre<93% (% of class in this pool) Course (1) (2) (3)

17. Beyond the FMCE: Exam comparisons #2 (Knight workbooks/small groups): 34 common exam q’s #3 (Trad recitations): 30 common q’s (17 are “tutor. materials”, 9 are “quant/trad”) (12 are “tutor. materials” 6 are “quant/trad”)

18. Beyond the FMCE: Exam comparisons ( Tutorial score - other course score) All q’ Tut mater. quant/trad (2) Workbook: +6 +7 +6 (3) Trad: +10 +14 +10 (All ± 2) N.B. 12 points is roughly 1 letter grade. Tutorial courses: significantly better exam scores: both conceptual and quantitative/traditional.

19. Other data Replication study (compare with UW) CLASS (attitudes/beliefs) Surveys (did you like, did it help?) All favorable (or neutral) for tutorials, ask for details!

20. 1110 Summary Compare Tut-based with “workbook/small group”  measurable diffs (FMCE, exams, CLASS) Compare Tut-based with “more trad rec”  significant diffs. Tutorials only one effect. (Instructors, course structure …!?) But in 1120, changing instructors + text => no impact

21. Phys 1120: Tut1 (Fa04) and Tut2 (Sp05) Attempt at replication. Main differences: Tut2 has… different instructor different semester different textbook follows up 1110 without Tutorials no long answer on exams

22. Summary (up front!) Despite changes in course elements, we replicated Tutorials + basic course structure. Result: identical (high) learning gains. (Final score matches our juniors. Hard exam!)

23. 1120 BEMA pre/post BEMA = “Brief E&M Assessment”, F04 (N=319) Pretest ave 26%

24. 1120 BEMA pre/post F04 (N=319) Pretest: 26% S05 (N=232): 27%

25. 1120 BEMA pre/post F04 (N=319) 26% -> 59%, S05 (N=232) 27% -> 59% g(ave, F04) =.44+/-.01 g(ave, S05)=.43+/-.01

26. 1120 E&M pre/post

27. Other data Common exam questions (no change) Replication study (compare with UW) CLASS (attitudes/beliefs) Surveys (did you like, did it help?) All results similar for both semesters!

28. Affect: survey results 1120 (Tut2) followed 1110 using Knight “workbook” small-group recitations. Asked at end: Which is better, Tut or trad rec? 39% vs 40% Which would you enjoy more? 39% vs 39%

29. 1120 mini-summary Different instructors, text, exam structures, semesters… same Tutorials and Conceptests: no sig diff on BEMA, CLASS, exams. Validated survey scores high. Slight differences in surveys: ~neutral student satisfaction. No disasters, room to improve

30. Bottom line Tutorials successful, productive course elements. Cost:$1500/LA/semester * (6-8 LA’s per course) Need 1.5 hr/week training session (TA’s too!) Benefits: Some LA’s => K-12 cert. (+ their learning gains very high) TA’s exposed to research-based learning.

31. Recommendation We should continue implementing Tutorials (and collecting data) Need support for LA’s, and training infrastructure (=> faculty or experienced grad student assigned to teach the TA’s/LA’s)
