Unformatted text preview: Transforming Upper-Division Quantum Mechanics Learning Goals and Assessment Steve Goldhaber †‡ , Steven Pollock † , Mike Dubson † , Paul Beale † and Katherine Perkins †‡ † Physics Dept., University of Colorado, Boulder, CO (per.colorado.edu), ‡ The Science Education Initiative (www.colorado.edu/sei) Introduction QM I Transformation at CU • Approach: – Used results from PER 1–4 – Developed learning goals (see next column) • Classroom Techniques: – Integrated concept tests into lecture – Modified Homework: justification of reasoning, estimation and math - physics connections – Hosted group homework sessions – Added tutorial sessions focusing on areas of known student difficulty 3,8 • Assessment: Developed the QMAT Learning Goals • Faculty input via interviews and a series of meetings • 18 faculty contributed their time • Sample skill-oriented goal: “Students should be able to sketch the physical parameters of a problem (e.g., wave function, potential, probability distribution), as appropriate for a particular problem.” • Sample content-specific goal: “Given a wave function and an observable operator, students will be able to calculate that operator’s expectation value” Measuring Learning • QMAT goals: – Reflect faculty learning goals – Assess student learning difficulties – Help faculty improve QM instruction • Question development: – Student interviews: elicit learning difficulties (5) assess question validity (21) • Administered: – Dec. 08 (N = 27), Apr. 09 (N = 36) • QMAT has 14 questions, 28 separate question items (mostly free response) Overall QMAT Results Spring 2009 student results grouped into 5 categories of learning goals covered by the QMAT.
