My Goal
Present foundational ideas in quantum mechanics including formalism, history, philosophy, and applications
Utilize limited mathematical descriptions of ideas where appropriate
Help students experience the utility of mathematical formalisms, empirical investigations, and deductive reasoning

Group and Individual Assignments
Groups with mixture of students Encouraged collaboration (formally and
informally) Good support of each other and peer
instruction Generated excellent out-of-class
discussions

Student Reaction—Precourse
High enthusiasm among honors students, philosophy majors, physical science majors, and former conceptual physics students
Students with limited quantitative backgrounds needed assurance about level of mathematical expertise needed
Students with limited philosophy backgrounds needed assurance of philosophy content

Content
Interdisciplinary nature appreciated Group work helpful having students helping each other
where they lacked expertise Some sensed we pushed students a bit hard on depth of
philosophy and physics Appreciated being able to understand subject student
had been told he couldn’t Physics text widely praised Enjoyed look at fundamental physics assumptions

Learning Activities
Group work helpful to support each other Synthesis paper very valuable Wanted more structure in philosophy Many wished for better integration of
philosophy and physics topics

Conclusions
A challenging course in quantum mechanics can be successfully taught to general education students
Physics can provide an avenue and motivation for these students to develop a facility with advanced mathematics
Integration of physics and philosophy content is critical
Group assignments are especially valuable in this kind of a course
