Tillfälligt slut
Participants in this workshop were asked to explore three related questions: (1) how to create measures of undergraduate learning in STEM courses; (2) how such measures might be organized into a framework of criteria and benchmarks to assess instruction; and (3) how such a framework might be used at the institutional level to assess STEM courses and curricula to promote ongoing improvements. The following issues were highlighted: * Effective science instruction identifies explicit, measurable learning objectives. * Effective teaching assists students in reconciling their incomplete or erroneous preconceptions with new knowledge. * Instruction that is limited to passive delivery of information requiring memorization of lecture and text contents is likely to be unsuccessful in eliciting desired learning outcomes. * Models of effective instruction that promote conceptual understanding in students and the ability of the learner to apply knowledge in new situations are available. * Institutions need better assessment tools for evaluating course design and effective instruction.* Deans and department chairs often fail to recognize measures they have at their disposal to enhance incentives for improving education. * Much is still to be learned from research into how to improve instruction in ways that enhance student learning.

New telescopes spanning the full electromagnetic spectrum have enabled the study of supernovae (SNe) and supernova remnants (SNRs) to advance at a breathtaking pace. Automated synoptic surveys have increased the detection rate of supernovae by more than an order of magnitude and have led to the discovery of highly unusual supernovae. Observations of gamma-ray emission from SNRs with ground-based Cherenkov telescopes and the Fermi telescope have spawned new insights into particle acceleration in supernova shocks. Far-infrared observations from the Spitzer and Herschel observatories have told us much about the properties and fate of dust grains in SNe and SNRs. Work with satellite-borne Chandra and XMM-Newton telescopes and ground-based radio and optical telescopes reveal signatures of supernova interaction with their surrounding medium, their progenitor life history and of the ecosystems of their host galaxies. IAU Symposium 296 covers all these advances, focusing on the interactions of supernovae with their environments.
