1. Developing A District Wide One-Week Unit on Light for Bellevue School District That Uses HOU! A Brain Storm! Jenifer Perazzo Pleasanton School District, Science Specialist/teacher 1st-5th Grade, LBNL Summer Worker Carl Pennypacker, HOU

2. Light Unit- the Need We believe that before a student can understand, for example, the phases of the moon, a deeper conceptual understanding of light must evolve in the student. We believe that before a student can understand, for example, the phases of the moon, a deeper conceptual understanding of light must evolve in the student. The National Academy of Sciences study “How People Learn Science” ( The National Academy of Sciences study “How People Learn Science” ( http://www.nap.edu/catalog/10126.html) indicates that children come to school with many rich and valuable preconceptions, based on their experience and reasoning abilities. But pre-conceptions do not have as great a predictive power as we may want. http://www.nap.edu/catalog/10126.html Most children emerge from Middle School believing moons phases are due to earth’s eclipse ( Nat. Assesments of Ed. Progress - NAEP)

3. Light Unit- the Need -- continued -- a bigger picture Most United States Science Curriculum is not coherent -- not a big theme interconnecting units, units don’t build on each other year to year little technology use or real data use, etc. Most United States Science Curriculum is not coherent -- not a big theme interconnecting units, units don’t build on each other year to year little technology use or real data use, etc. Try to embed HOU into the whole district innate in the curriculum, easily.

Build good pedagogy (as evidenced by many HOU teachers) into a good recipe that allows teachers to teach creatively, but the same content in all classes, and also use best pedagogy (CPU physics template) Build good pedagogy (as evidenced by many HOU teachers) into a good recipe that allows teachers to teach creatively, but the same content in all classes, and also use best pedagogy (CPU physics template)

4. Overview: Bellevue Washington -- all curriculum on web, teachers teach same units:

5. Overview: Bellevue Washington -- continued8th grade physics (CPU by Goldberg) for all students, and three years of science in High SchoolCurriculum coherence and fidelity biggest driver for improvement of teaching and learningTeacher subject matter knowledge with real science courses being implemented.90 minutes of in-service a week, and 5 days of inservice each summer.
