The operation of rounding is shown to lead into an investigation of an abstract mathematical system. Properties of the system are discussed and graphs of the rounding function are drawn. Some questions for discussion are given. (MP)

Conjecture and proof, as opposed to numerical calculation, are presented as being the primary focus for teaching mathematics. (MP)

Describes the Howard B. Owens Science Center at Prince George's County (Maryland) Schools, which concentrates advanced equipment and highly trained teachers to give visiting students and teachers hands-on experiences they cannot get in the classroom. The center boasts computer-controlled rocketry, laboratories, exhibits, and lectures introducing…

Discusses the wilderness lab medium for executive and team development. Provides insights on key design elements and facilitation challenges useful to potential wilderness lab "consumers." (JOW)

The progression from simple interest to compound interest leads naturally and quickly to the number e, involving mathematical discovery learning through writing programs. Several programs are given, with suggestions for a teaching sequence. (MNS)

Some examples for investigating shapes in the environment are given. Circular objects, triangulation, symmetrical designs, and further investigations are listed. (MNS)

Offers a comparison of the pedagogical philosophies of five pioneers in educational computing: Patrick Suppes, Arthur Luehrmann, Alfred Bork, Symour Papert, and Thomas Dwyer. (AEA)

A plea is made that mathematics should be taught the way that mathematicians do it, using an exploratory approach rather than rule learning. (MNS)

A study of a class of numbers called 'Good numbers' can provide students with many opportunities for investigation, conjecture, and proof. Definitions and proofs are presented along with suggested questions. (MNS)

The use of invertebrates as classroom "pets" can develop students' skills in scientific inquiry and instill respect for science. Few materials are needed for projects involving invertebrates. Suggested activities using snails, crickets, earthworms, crayfish, and guppies are offered. (DF)

Egg, caterpillar, chrysalis, adult. Children watch and nurture a magical metamorphosis. (Editor)

Outdoor education is often delivered through games and activities such as nature hikes or observing an ecosystem within a 1-foot circle on the ground. Often, participants look closely at the earth only for that brief moment. Wilderness survival is another way to teach about the outdoors. It offers skills that encourage participants to become more…

Eight prominent learning theories are summarized, compared, and discussed for implications to adult learning. (MS)

A program developed to introduce students to urban planning concepts answers the need for an interdisciplinary approach to urban ecology. (KM)

Suggestions and procedures are offered for an effective open classroom. (MM)
