A Monte Carlo Study of the Robustness and Power Associated with Selected Tests of Variance Equality when Distributions are Non-Normal and Dissimilar in Form

Description: When selecting a method for testing variance equality, a researcher should select a method which is robust to distribution non-normality and dissimilarity. The method should also possess sufficient power to ascertain departures from the equal variance hypothesis. This Monte Carlo study examined the robustness and power of five tests of variance equality under specific conditions. The tests examined included one procedure proposed by O'Brien (1978), two by O'Brien (1979), and two by Conover, Jo… more

Materials, Practices, and Perceptions Associated with Prior Participation in an Aerospace Education Workshop: a Case Study

Description: This qualitative study was conducted in a large north Texas school district. The subjects were four elementary teachers who had previously attended a summer aerospace education workshop. The researcher observed in each classroom during science instruction and other areas where aerospace concepts might be taught to determine material usage, practices, and perceptions associated with teaching aerospace. The teachers' lesson planbooks, textbooks, and supplementary materials were also examined by t… more
