Phenomena that occur in microdroplets are described to the undergraduate chemistry community. Droplets having a diameter in the micrometer range can have unique and interesting properties, which arise because of their small size and, especially, their high surface area-to-volume ratio. Students are generally unfamiliar with the characteristics of…

Describes and evaluates a technique used in two science lecture courses (biochemistry and introductory meteorology), in which lectures were interspersed with frequent, brief discussions within spontaneously formed small groups. Some differences were found in the ways the two professors managed the technique, but both felt in-class participation…

The discussion board feature that is included with most course management software packages is a potentially valuable tool to augment instructor-student interactions in science lecture courses and increase student motivation.
