  1. Assessing Methods of Instruction of Solar System Concepts Michael C. LoPresto 2009 HOU Annual Conference Yerkes Observatory

  2. Verifying the Principles of How People Learn and How Students Learn-Science though Assessments of Lecture Tutorials on Solar System Concepts & Astronomical Misconceptions

  3. How People LearnNational Academies Learning Environments 1-Learner-Centered 2-Knowledge-Centered 3-Assessment-Centered 4-Community-Centered

  4. How Students LearnScience in the ClassroomNational Academy of Science Good Science Instruction 1-Deal with Preconceptions; diagnostic assessment 2-Active & Collaborative; Inquiry based 3-Reflection; Formative Assessments

  5. Part 1:Lecture Tutorialsby Edward E. Prather, Tim P. Slater, Jeff Adams, Gina Brissenden, and the Conceptual Astronomy and Physics Education Research (CAPER) team • a) elicit student misconceptions • b) confront incomplete, or inaccurate ideas, • c) resolve these contradictions, • d) demonstrate to students the power of their conceptual models.

  6. Lecture-Tutorials “How-To” Lecture for approximately 20 minutes on the core required background knowledge Ask conceptually challenging, multiple-choice questions Have students work in pairs-LTs take, on average, five minutes per page-Call Time! Debrief; Give students a few minutes to ask questions; Ask them a series of questions http://astronomy101.jpl.nasa.gov/index.cfm

  7. Testing the Pedagogy Star Properties Concept Inventory (SPCI) -by Janelle Bailey Assessments; diagnostic formative-”clickers” summative 11-Tutorials from LTIA-(Prather et. Al) vs. Lectures

  8. Pre; [N=89]=27% Post; Lec. [N=47]-57%; g=0.4 Tut. [N=41]-63%; g=0.5 (without clickers-g~0.3) -formative assessment!

  9. Solar System Topics • Size & Scale-Solar System Walk • Planet Types-Comparative Planetology • Formation • Extra Solar Planets • Debris • Terrestrial Planets • Jovian Planets

  10. Turning a Lecture into a Tutorial Write out Lecture Write out main points you want to teach Turn into sequence of questions Test with students

  11. Formation of Solar System • Planets form from the leftoversof star formation • Distance from the sun controls temperature • Temperature controls what materials condense • Inside rock-metal condensation line-no planet • Beyond r/m line; inside frost line-rock/metal only • Beyond f-line, ices form on rock-metal cores • Inside f-line; higher temperatures, gases move moving too fast to capture-Terrestrial Planets. • Beyond the f-lin; lower temperatures, gases move slowly, captured by larger objects-Jovian Planets. • Jovian planets more-evolved • The different temperatures at different distances from the sun is the most important factor • Not all materials become part of a planet or planetary-system; asteroids, comets,meteors.

  12. Tutorial

  13. Assessment Questions

  14. Summative Assessment Results

  15. Surface Conditions of Terrestrial Planets

  16. Summative Assessments

  17. Part 2:Visual Assessments & Tutorials Comets & Extra Solar Planets

  18. Comets Diagnostic Assessment • Make sure that your drawing clearly showsany differences between the size of the coma and length of the tail and the direction the tail is pointing.

  19. [N=93] 46% common misconception 23%-tail direction 13%-tail size 4%-coma size

  20. Tutorial vs. Lecture

  21. Formative Assessment

  22. Questions fromSolar System Survey Pre [N=100]-14% 46% chose ‘b’ Post; lec [N=46]-48%, g=0.40 tut [N=38]-55%, g=0.48 Chose ‘b’ lec.-26%; tut.-18%

  23. Pre [N=100]-35% Post; lec [N=46]-46%, g=0.17 tut [N=38]-63%, g=0.43

  24. Summative Assessment Lecture, N=46 scores dropped to; 9%, 30% and 59% Misconceptions dropped to 15% Tutorial, N=38-scores rose to; 61%, 84% and 89 % Misconceptions dropped to3% One respondent!

  25. Extra Solar Planets

  26. Tutorial

  27. Lecture- exoplanets.org Mostly on “front” Even on “back”

  28. Conclusions Students did better with; Tutorials, Formative Assessments Learner,Knowledge, Community & Assessment Centered; Active HPL; HSL-Science -WORK!

  29. What’s Next? • All HPL vs. None? Tutorials & Formative assessments (with clickers) vs. Lectures Alone • Study on Misconceptions using HPL principles

  30. Thank You! Carl Pennypacker Steve Murrell
