This article reports the effects of a science, technology, and society (STS) teaching approach on the knowledge and attitudes of preservice science and mathematics teachers in Uganda toward global science and technology-based problems and/or threats. The responses of a baseline or control group (N = 50) and an experimental group (N = 50) to five questions on the preassessment indicated how little knowledge these preservice teachers had regarding these issues; however, the responses of the experimental group on the postassessment also (...) showed how quickly a short treatment using an STS teaching approach could improve their knowledge. These results also inform planning for science education in Uganda to achieve science literacy in general, and particularly the understanding of environmental science problems and/or threats facing Ugandan citizens.

The responses of a convenience sample of 83 secondary preservice and preeducation students in three university classes were compared to each other and to a national sample of 1,492 adults on a national poll of science knowledge. The results of the data analyses using simple ANOVA and two-tailed t tests indicated that preservice secondary science teachers in a secondary science methods class are significantly more science literate than preeducation majors and the na tional sample. They were not significantly more science (...) literate than preservice and in-service science teachers in an environmental science methods class. Chemistry majors were significantly more science lit erate than other science and health majors. Additional comparisons between males and females, graduates and undergraduates, and older and younger (younger than 28) students indicated males, graduates, and older students are significantly more science literate than females, undergraduates, and younger students.

The article describes a capstone engineering course for preservice and inservice secondary science and mathematics teachers and shows teacher attitudes toward engineering before and after the course and results of a comparison with a convenience sample. It also gives the results of the attitudes of high school student experimental and control groups toward engineering in a pretest-posttest design. Four findings were made: (a) The science and mathematics preservice and inservice teacher attitudes toward engineering became more favorable after the capstone course; (...) (b) the attitudes of the convenience sample of secondary graduate students were less favorable toward engineering than they were among the treatment group in the capstone course; (c) the attitudes of the experimental group of high school students became significantly more favorable toward engineering after a 3-week unit on engineering; and (d) the attitudes of the experimental group became significantly more favorable toward engineering than did those of the control group after the 3-week unit.
