A Road Less Traveled: Industrial Ph.D. Physicist to High School Physics Teacher Role of Colleges and Universities in Preparing Future Physics Teachers Cornell University June 19, 2006 Christopher Olszewski Buffalo State College 1300 Elmwood Ave., Buffalo, NY 14222 cjo496@yahoo.com Personal Background 1977: B.Sc. McGill Univ. 1980 1984: Ph.D. Univ. of IL. (U-C) (Exp. Part. Physics) AT&T Bell Labs 1988: Brookdale Comm. College (Intro Calc) 1990 1995: AT&T Labs 2000: Tellium 2003: Tellium died 2004: Buffalo State College (Alt. Cert. Prog.) 1999: Project Astro Nova 2000 (3rd Grade Astronomy) 2010 2 SUNY - Buffalo State College’s Alternate Certification Program Buffalo State College’s (BSC’s) program includes: Summer academy of showcase courses (mechanics, E&M, new physics teacher workshop) • Extensive student-mode experiences • Significant Pedagogical Content Knowledge (PCK) • Guided reflections • Student-centric reformed teaching (consistent with Reformed Teacher Observation Protocol (RTOP)) • Encouragement of student discourse and whiteboards Physics Education Research (PER) seminar course Education courses (state mandated) Field work 3 Results of BSC’s Alternative Certification Program Significant changes to my concepts of good physics learning and teaching • Previously: largely teach as taught • Now: much more student-centric New concepts documented in • Class assignments • Spontaneous class notes • Guided reflections • Learning commentaries (thinking changes in one physics idea – before & after) Compared old and new concepts of good teaching later 4 Examples of Significant Changes to Personal Beliefs of Good Physics Teaching What I Believed Then What I Believe Now Different Types of Knowledge Really, audio and visual input are the keys: the teacher speaking, and the students listening Kinesthetic learning experiences (and other sensory experiences) give students a good basis for new knowledge in an entirely different way (Arons, 1997) Student Verbalization & Explanations Student explanations are frequently in error: teacher-given explanations are much preferable Having Having students students explain explain their their reasoning reasoning is is valuable valuable to to them them and and their their classmates classmates Lab Activities Laboratory exercises should have a clear procedure, to minimize the students chance of making mistakes and errors Most laboratory exercises should be open-ended unstructured activities, with broad clear goals calling on 5 student creativity and thoughtfulness Examples of Significant Changes to Personal Beliefs of Good Physics Teaching (Cont’d) What I Believed Then What I Believe Now Process of Science / Learning At this level, students should do most of their learning on their own: They’ll have to learn to work on their own eventually anyway Science is done frequently in groups. Therefore, many activities should be done in groups, as a demonstration of “real science” Encouragement of Thinking Frustration in students should be minimized by the teacher by clear explanations, appropriate problems, and demos Students should encounter frustration regularly as they learn: Intellectual dissonance / discomfort are essential 6 Varying Levels of Effects of Program Elements Assessed influence of various program elements on changes in my beliefs about good teaching • Used class notes and assignments Four approximate categories of effects: • Triggering element of changed belief • Essential component of changed belief • Very strong support of changed belief • Strong support of changed belief T E V S 7 Effects of Program Elements on Changes in Beliefs of Good Teaching Program Elements Changed Belief Topic Showcase Courses Stdt.
