This article describes the implementation of high-altitude balloon (HAB) research into a variety of undergraduate atmospheric science classes as a means of increasing active student engagement in real-world, problem-solving events. Because high-altitude balloons are capable of reaching heights of 80,000-100,000 ft (24-30 km), they provide a…

Preservice preparation courses for elementary teachers of science can provide opportunities to build pedagogical content knowledge. One common concern of preservice teachers is how to cope with a preplanned lesson that does not proceed as planned. Providing opportunities for preservice teachers to experience the unexpected actually immerses them…

Presents a scenario about Ignaz Semmelweis' work with childbed fever. Provides study questions about the scenario as well as teaching notes. (YDS)

Describes procedures for a demonstration that features an exploding can. This demonstration prompts students to critically analyze the release of energy in an exothermic reaction, the work done in such a reaction, and the enthalpy. (DDR)

Discusses the merits of investigative labs and how they change the role of students from passive direction followers to more creative and analytical thinkers. Focuses on the University of Minnesota's program in the Virgin Islands that involves undergraduates in research. (DDR)

Discussion of changes in science education and scientific literacy is presented in the form of a dialog between the author and his alter ego. Structure of science, myths, facts, methods, and critical rationality are considered. Suggests that scientific principles once considered basic and unchanging are giving way to critical thinking. (DH)

Described are ideas for the development of problem solving in the context of chemistry. Strategies for improving students' problem solving abilities are included. (KR)
