A discussion of what E=mc2 means and other issues associated with the equation are presented. The differences between matter, mass, and energy, a derivation of the equation, the history of the word mass and examples of how it is used, misconceptions surrounding the equation, and a discussion of uranium fission are included. (KR)

Discusses the Jasper Woodbury Problem Solving Series, a video-based instructional macrocontext for complex mathematics problem generation and solving. A theoretical framework of assumptions about goals, learning, instruction, and learning materials is provided. Design features and typical teaching activities are described. Three teaching models…

Environmental education is an interdisciplinary approach that draws on biology, mathematics, chemistry, social studies, and humanities and provides a balanced, comprehensive perspective. Knowledge and skills required are applicable to regional, statewide, and global concerns. Methods include infusion, issue investigation and action, and educating…

A procedure for estimating the speed and distance of plane, assuming the speed of sound and the velocity of the plane are constant, is described. (KR)

A procedure for measuring the speed of light using the assumption that the frequency of light remains unchanged as it moves from one medium to another is presented. A laser with a known wavelength and frequency in air was used as a light source. (KR)

A study of 44 teachers who had experience in implementing problem-solving activities in technology education classes concluded that problem-solving activities are becoming an integral part of technology education. The outcomes of such activities depend on the processes and thinking techniques taught and applied. (JOW)

The thinking-out-loud procedure provides teachers with an excellent mechanism for collecting information about students' thought processes and affective states during problem solving. Mathematics teachers can implement this process by modeling it during whole-class problem-solving sessions, proceeding slowly and encouragingly, working with small…

A sample of novel verbal problems which can be solved by using systems of linear equations with free variables is presented. The procedure of Gaussian elimination is used to solve the system. (KR)

This paper discusses a teaching approach in which children serve as mediators in the delivery of instructional content. It describes programs that have been used effectively with students having academic difficulties, reviews the relative advantages and disadvantages of these methods, and proposes ways to utilize peer-mediated instructional…

Discusses research into problem-solving skills that have caused the theoretical methods of teaching and learning problem solving to evolve rapidly. Presents issues and questions that still need to be explored. (PR)

Considers the role of word problems in physics education and proposes that word problems serve as exemplars of prototype categories that play a key role in enculturating students into the community of the physics literate. Contains 25 references. (ASK)

When people feel they belong, they care about what others think of them. In conducting teacher workshops, author has encountered growing numbers of teachers who report a whole new class of students who act as if they don't care about their behavior and for whom authority has little or no meaning. This article discusses strategies for creating…

Discusses the problem-based learning format as it relates to the education of medical students. Describes key objectives in the education of physicians and questions how effective medical schools are in achieving those key objectives using a problem-based format. (CCM)

Suggests that simple riddles can be used effectively to make students interact in science class. Proposed teaching methods require the student to provide answers to riddles in order to develop the discussion about a given topic. Presents sample riddles related to elements and their compounds. (WRM)

A professor and a student offer their views of problem-based learning as experienced in a University of Delaware undergraduate class in physiology. Vignettes of class activities and discussions are interspersed with a review of the history of and research on problem-based learning. (DB)
