  1. EPO and Pre-service Science Education Astronomical Society of the Pacific Annual Conference Pinky Nelson, Western Washington University September 18, 2006

  2. Introduction / Outline • Why me? • Affirmation of EPO people and progress! • Needs and of preservice Teachers • Comments about preservice education • WWU elementary preservice program as an example • A suggestion for a significant EPO contribution Sponsored by the National Science Foundation under Grant No. HER-0315060

  3. Needs of Preservice Teachers Two recent views: Lillian McDermott, Leo Kadanoff • Deep enough content knowledge of science disciplines that they will be teaching • Deep understanding of scientific inquiry • Deep understanding of learning research and theories • Content Specific Pedagogical Knowledge • Knowledge of and experience with effective materials • Knowledge of children (ed psych stuff) • Knowledge of how to function in a professional learning community • School knowledge (rules, classroom management) • Commitment to equity and useful tools • Confidence in their own ability to learn Sponsored by the National Science Foundation under Grant No. HER-0315060

  4. Comments on Preservice Education • Current model is failing (sustaining the status quo) • Elementary students enter with severe deficits • 75% are not proportional reasoners • Science knowledge is at ~ grade 6-8 standards • Secondary students have weak conceptual understandings, poor (traditional) teaching models • Students are not “dumb”, they have been grossly underserved by the system • Preservice reform must include K-12 reform • Any reform should plan to evolve • If we are successful, students will change over time Sponsored by the National Science Foundation under Grant No. HER-0315060

  5. An example from Western Washington University (K-8 endorsement program) • NCOSP Partners • University with a large teacher preparation program • Four neighboring two-year colleges • 28 school districts • Washington State LASER • One of the goals • Help WWU and CC transfer preservice students become confident science learners Sponsored by the National Science Foundation under Grant No. HER-0315060

  6. New Requirements for El Ed major • Five Science Content Classes (quarters) • 3 quarter sequence--phys, biol, geol • 1 quarter capstone--Inquire science (chemistry) • 1quarter nature of science--Science and Society • Two Science Pedagogy Classes • Science Methods • Science practicum Sponsored by the National Science Foundation under Grant No. HER-0315060

  7. Development Stucture • GUR Working Group ~ 25 Faculty, 2-3 Teachers on Special Assignment • 3 Sub-groups Phys, Biol, Geol • No hierarchy Sponsored by the National Science Foundation under Grant No. HER-0315060

  8. Guiding Documents: • How People Learn • Understanding by Design • Physics Education for Teachers • Learning Cycle Model • Purpose • Initial Ideas • Collecting and Interpreting Evidence • Summarizing Questions (Reflection) Sponsored by the National Science Foundation under Grant No. HER-0315060

  9. Developing the courses • Issues that we faced: • Staff Development • Survey course vs. Depth • Integrated vs. Discipline-based • Innovated vs. Research-based • Academic freedom vs. Common Course (including assessments) • University vs. Two-year faculty • Full-time faculty vs. Part-time faculty • Existing vs. Home-grown Sponsored by the National Science Foundation under Grant No. HER-0315060

  10. Initial Course Implementation Sponsored by the National Science Foundation under Grant No. HER-0315060

  11. Participating Institutions (Fall 2005): EVCC, SVCC, WCC & WWU PET curriculum Constructivist: based on experiences, investigations, and discussions in the classroom No textbook Part of a science sequence for elementary education students Approximately 80 students participated in Fall 2005 Data, data, data content assessments student surveys of students’ beliefs teacher interviews student interviews observations K-16 Reform-Based Science InstructionNew Physical ScienceGUR Course at a Glance

  12. Preservice Elementary Teacher Performance (PET Course) 100 90 80 70 EvCC 60 50 Percent Correct (%) WWU 40 SVC 30 20 10 0 Pretest Posttest PET Student Assessments N=53

  13. Students’ Views of the Nature of Science The main skill I expect to get out of this course is to learn how to reason logically about the physical world. “… a lot of the things that I just take for granted I had to question and then realize that I was wrong on a lot of the things I thought and the good thing is that because we did experiments… we had to figure out how to learn it ourselves and the teacher didn’t just tell us how to think, it counteracted what I thought that was wrong so it forced me to realize what was wrong and not go back to what I was thinking before”. -WWU student

  14. Learning science made me change some of my ideas about how scientific phenomena can be used to understand the world around me.

  15. When learning science people can understand the material better if they relate it to their own ideas. “…I just learn information like for a test, then I forget it, then I’ll just return back to what I thought before but this way I remember it better”. -WWU student

  16. Foci of Observation: Design Implementation Content Experienced by Students Classroom Culture Capsule Ratings of Quality of the Lesson Level 1: Ineffective Instruction Highly Unlikely to contribute to students’ understanding. Level 2:Elements of Effective Instruction Some evidence of learning but serious problems in design, implementation, or content. Level 3:Beginning stages of Effective Instruction Somewhat limited in its ability to contribute to students’ understanding. Level 4:Accomplished Effective Instruction Quite likely to contribute to the majority of students’ understanding. Level 5:Exemplary Instruction Highly likely to contribute to all or most students’ understanding and develop capacity to do science. Observations:Using HRI Observation Protocol

  17. Standard GUR Design: 4 Implementation: 3.7 Content: 3.7 Culture: 3.8 Capsule: 3.2 New GUR Design: 4.4 Implementation: 3.8 Content: 4.1 Culture: 3.9 Capsule: 3.9 Rating Averages Standard Physics GUR: 6 observations of three courses New Physics GUR: 8 observations of four courses

  18. Content As Experienced by Students • Quotes from Students in Physics Class • “Although it was less than a year ago that I completed a Physics AP class in High School, I was surprised by how often my own ideas were challenged and changed by the basic ideas taught through this elementary curriculum” • “…of all the courses I took this quarter, I believe I showed the most growth in SCED 201. It is amazing to look at the initial ideas in my binder and see how much progress my ideas and thoughts have made over just a unit in the curriculum. I also noted a lot about my own thought processes and the way that I learn”

  19. Content As Experienced by Student “I believe that this course will be extremely useful for me in the future. Even though I am not going to be a science teacher, I am planning on being a Spanish teacher. Before taking this course, I thought that the science GURs would be useless for my major, and that all science courses were lecture-based. But, rather than just teach me something about science in a new way, this course taught me about how I learn, and showed me that there are different approaches to go about teaching materials that can be carried across the disciplines, which I will be able to bring into the classroom as a Spanish teacher.

  20. Classroom Culture “At the beginning I was very nervous about it because I don’t feel like I’m a strong science thinker. I was really afraid to verbalize and vocalize my opinions and what I was thinking on a topic, but after a week or so I began to become really comfortable because I realized that the reason everyone’s talking about it is to help everyone learn. And when someone would say something that was incorrect, no one would care because we all just wanted to help them understand what was actually going on so…I was very comfortable by then.” - WWU Student

  21. Example: Selecting the Biology “Big Ideas” Taken from: Washington State Standards National Science Education Standards AAAS Benchmarks for Science Literacy Sponsored by the National Science Foundation under Grant No. HER-0315060

  22. Content: Life Systems “Big Ideas” • Food serves as fuel and building materials for an organism. Sugars are an example of food, but water, carbon dioxide, and oxygen are not. • Using the energy from light, plants make their own food - in the form of sugars - from carbon dioxide (in the air) and water. Nothing else is required for this process • Plants transform the energy from light into chemical energy in the sugars. • Animals cannot make their own food, but must acquire it by consuming plants or other animals that have consumed plants. More… Sponsored by the National Science Foundation under Grant No. HER-0315060

  23. Content: Life Systems “Big Ideas” (cont.) • Organisms grow by breaking down the food and assembling the breakdown products into their body structures. • Organisms gain energy for their life processes breaking down energy-rich food into simpler substances with less energy. The energy is used for growth and body functions. Other energy is released as heat. • If not used immediately for fuel or building structures, the breakdown products can become part of body structures that serve as energy storage for later use. Sponsored by the National Science Foundation under Grant No. HER-0315060

  24. Overarching Scientific Process “Big Ideas” • The Universe is Understandable • Scientific Ideas Are Subject to Change • Scientific Knowledge is Durable • Science Explains and Predicts • Science Cannot Provide Complete Answers to All Questions • Science Demands Evidence • Science is a Blend of Logic and Imagination • Science is not Authoritarian Sponsored by the National Science Foundation under Grant No. HER-0315060

  25. Data from summer pilot 2005Investigating the Flow and Matter and Energy in Living Systems Four Cycles • What is food for living organisms? • How do plants get food? • How do organisms use food? • How does matter and energy cycle in living systems?

  26. HRI Life Science Assessment: Pre and Post Scores * Post-test scores significantly greater than pre-test score (p < 0.05), 1-tailed paired samples t-test. Effect size = 1.39 standard deviations. Gain score= .51. N=165

  27. Comparisons by Grade Level Controlling for pre-test scores and other demographics, high school teachers scored significantly higher than elementary and middle school teachers (effect sizes of 0.45 and 0.31 standard deviations, respectively). However, no significant differences between gain scores (ES=.49, MS=.48, HS=.57). N = 87, 42, 36

  28. Comparisons by Gender No significant differences by gender. Gain scores: M=.54 F=.50

  29. What have we learned? • Less is more • Initial perceptions of “academic freedom” must be addressed (student- vs. faculty-centered) • Implementing reformed courses is material, staff, and faculty intensive w/ implications for sustainability • Team teaching helps • Lesson Study helps • Staff development is key • Interpersonal relationships are critical • Course revisions being made based on student and faculty feedback--methods course. • Can’t do it all – where is the place for chemistry, astronomy, environmental science….? Sponsored by the National Science Foundation under Grant No. HER-0315060

  30. A Suggestion for EPOers • Assemble teams to develop and test three or more one-semester astronomy content courses for future teachers • Solar System and Stars for Elementary • The Universe for Secondary • Copy the Physics for Elementary Teachers format (for example) • Pilot these materials so you know how they function • Include an instructor’s guide and staff development • Use proven development protocols (UBD) • Start by choosing learning goals (Benchmarks 6-8) • Create and test assessments • Design inquiry-based activities • Include cool simulations and data where it makes sense • Build in a robust evaluation plan from the start and pay attention • Don’t worry about missions or even NASA--worry about students learning important ideas Sponsored by the National Science Foundation under Grant No. HER-0315060
