A primary objective for science education is to impart robust knowledge that has applicability to real-world problems. This article presents research investigating the relationship between adolescents' conceptual understanding of the biological basis of HIV and critical reasoning. Middle and high school students were interviewed about their…

This paper examines the images middle school students have of science and technology, the workplaces, and the relevant professions. It also describes the effect on these images caused by an instructional initiative, "Investigation into Science and Technology" (IST), designed to introduce students to science and technology in the "real life."…

There is a widely and deeply held belief on the part of the author's white colleagues that racism is something done by individuals through overt or covert actions against other individuals.
