The first phase of an evaluation of the new AS/A-level course "Advancing Physics," sponsored by the Institute of Physics, is now complete. It shows that the course has achieved very high satisfaction ratings from teachers of the course, and that a majority of these teachers see it as achieving its main aims. The first phase of the evaluation was designed to pinpoint aspects of "Advancing Physics" that offer scope for improvement. Two such aspects have been identified: course planning and use of the CD-ROM material, and arrangements for coursework in the examination. (Contains 2 figures and 5 tables.)
