ongeometrical optics with a survey of wave optics. In order to compensate for the lack oflaboratory work, an optics project was introduced alongside class demos. Studentsbrowsed for possible topics for a couple of weeks and then proposed one based oninstructor’s feedback. The project concluded with a short presentation of the work infront of the class and a brief written report. In order to increase class interest in theproject, the presentation took the form of a competition and the winner(s) were chosen bythe class, who judged the presentations according to preset criteria. Student feedback wasrecorded and quantized, and the peer evaluation and feedback were returned to thepresenters. The winners received small prizes in recognition of their
