26. 4 October 2010XIII SEMANA DE LA ENSENANZA DE LA FISICA Main Message Understand ALL the different skills that students need to solve a problem. Help them break a complex problem into smaller pieces.

27. 4 October 2010XIII SEMANA DE LA ENSENANZA DE LA FISICA An Example Typical of EARLY upper-division work for physics majors and many engineers. Solution requires: –many mathematical strategies, –many geometrical and visualization strategies, –only one physics concept. Demonstrates different use of language.
