A beech leaf, garnet crystals, trilobite fossils--brought by children aged three to twelve transform the science room. Investigates the importance of learning materials that children bring to the classroom at no expense. (Author/RK)

Teachers of an integrated elementary classroom used cookie-sharing time as a learning experience for students. Responsible for dividing varying amounts of cookies daily, the students learned to translate their experiences to graphs of differing sophistication and analyses.

This issue presents an initiative problem, rules for rope push, exercise illustrating dependence on schedules, how to experience a handicap, maple sugaring project, assignment bridging the generation gap, simulating literary experiences, and local…

A situation is presented that is intended to lead to open-ended mathematical discussions that allow students to conjecture, discover, and prove mathematical statements. (MP)

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)

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

By working through a series of problems, undergraduate psychology students in an introductory statistics course discover for themselves the main topic of the lesson. A lecture follows to conceptualize and clarify the topic. (RM)

This discussion of ways to use spirolaterals in the classroom includes making conjectures, hypotheses testing, and proofs, as well as a number of examples. (MP)

A systematic search is given for products where reversing the digits does not change the answer. Related questions are suggested that can be solved by the same discovery approach. (MP)

Goals of the Children's Museum of Boston are to encourage curiosity, skepticism, and realism while providing opportunities for discoveries and new insights. The museum addresses the needs of young children through adolescents by providing a multicultural environment and participatory learning centers. (JDD)
