Requires students to develop hypotheses in which a common invasive species will succeed. Focuses on the red imported fire ant in the Southeastern United States, which is a non-native invasive species. (Contains 17 references.) (YDS)

An interactive computer/videodisc learning approach to the conventional laboratory approach for learning biology concepts and science process skills were compared. The two approaches appear equivalent when evaluated by traditional learning outcomes, but the interactive videodisc strategy was significantly more time efficient than a traditional…

Many educators assert that the acquisition of thinking skills by students is of primary importance to science education today. This study was designed to examine the effect of an instructional approach on achievement in science process skills when compared to a more conventional method of science instruction. The DIAL(SPS)2, a directed approach to…
