In this experiment, students carry out a modern organocatalytic reaction using IMes·HCl and NaOH to catalyze the formation of 1,3,4-triphenylcyclopentene from cinnamaldehyde and chalcone in water. Deprotonation of IMes·HCl with NaOH forms the "N"-heterocyclic carbene IMes that reacts with cinnamaldehyde to form a homoenolate equivalent…

A well-known experiment for the measurement of the acceleration of gravity is carried out on a personal computer using standard software for a sound card in a non-canonical way, which provides an improved, more accurate, result and is a useful teaching method for a traditional classroom experiment. (Contains 3 figures and 1 footnote.)

Although the teaching of photosynthesis occurs yearly in elementary classrooms, one thing that makes it challenging is the inclusion of English language learners (ELLs). This article presents several activities for teaching and assessing of photosynthesis in a third grade classroom. The activities incorporate the photosynthesis content, teaching…

This book is provided as a guide, encouragement and handbook for faculty to introduce digital media in language they can understand and provide strategies and activities they can quickly assimilate into their teaching. The authors are excited that more people will be able to benefit from the powerful help and guidance contained in this book. This…

In this paper, experiments with equal-length and different-length coupled pendulums were carried out measuring the frequency of energy exchange between them using microcomputer-based technology. The experiment described in this paper would be most appropriate for an introductory mechanics laboratory course. (15 references) (LZ)

Featuring an increased emphasis on the way today's changing science and technology is shaping our culture, this Second Edition of "Teaching Science in Elementary and Middle School" provides pre- and in-service teachers with an introduction to basic science concepts and methods of science instruction, as well as practical strategies for the…

This guide is intended for teachers and other educators confronting the challenge of using technology to enhance the way they teach science. Accompanying the recent boom in education Web sites has been the production of guides and guidelines, models, and methodologies for planning technology reforms in school districts, school buildings, and…

The author suggests the computer simulation game as a powerful motivational and teaching tool in many grades and subject areas. He briefly describes a few social studies and science computer simulation games. (SJL)

Describes the construction of capacitors using commercially available double-sided printed circuit boards. Presents activities using these capacitors. (PR)

H-cards have most of the advantages of traditional flashcards. They can be examined in a particular order or at random. In CD-ROM format, they are fairly portable since in many colleges and universities, each student is required to have a laptop computer. In online format, it is easy to add new h-cards to an existing set, and errors can be…

Describes the Software Teaching of Modular Physics (SToMP), a software package that is structured to be a complete learning and teaching environment. Allows students to explore and learn about physics topics without necessarily having to refer to teachers or to other resources. (DDR)

Describes a project that explores the use of interactive computer software for teaching Einstein's special theory of relativity to secondary students. Also describes ways to use computers to help students visualize and experiment with otherwise inaccessible phenomena. (ZWH)

Contains a reading list of articles published in 1985 covering 14 biological topics. Includes descriptions, procedures, and references for 26 experiments. These investigations deal with selected concepts in biology, ecology, chemistry, and physics and include computer-based instruction. (ML)

Presents pendulum lab results as an example for students on the write-up of experiments. (PR)

Uses of Intermedia, computer software designed to help instructors express relationships between concepts in the sciences and humanities, are discussed. The kinds of educational problems Intermedia was intended to address are described, some materials created using it are surveyed, and experiences with Intermedia in various educational contexts…
