Discusses openness involving assessment, including sharing information, involving professionals, examining and revising criteria, benefits of openness, and sharing responsibility for good mathematics work. (MKR)

The Core-Plus Mathematics Project (CPMP) is a four-year program emphasizing mathematical modeling, featuring full use of graphing calculators, building on the theme of mathematics as sense-making, and involving investigations of real-life contexts that lead to reinventing important mathematics. (MKR)

The Center for Occupational Research and Development (CORD) developed an applied mathematics course that integrates algebra, geometry, trigonometry, and other strands; centers around hands-on laboratory experiences; and uses real-world problems found in the world of work. (MKR)

The Hawaii Algebra Learning Project (HALP) developed a curriculum that intertwines algebraic content, instructional methods, and assessment techniques with a problem-solving focus. (MKR)

Discusses the World Wide Web, resources of interest to mathematics teachers, and starting points on the Web. (MKR)

Presents a brief life history of Maria Goeppert Mayer who won the Nobel Prize in Physics in 1963 for her work in atomic physics. (JRH)

Uses a diode array spectrometer to explain why blue objects appear red when viewed through the yellowish amber lens of "blue blocking" sunglasses. (JRH)

Describes experiments designed to investigate the cooling rate of microwave-boiled water as compared to that of stove-boiled water. Concludes that within experimental limits, microwave-boiled water and stove-boiled water cool at the same rate. (JRH)

Reports on the implementation of a relatively low-cost, versatile, and intuitive system to teach basic mechanics based on the use of a Charge-Coupled Device (CCD) camera and inexpensive image-processing and analysis software. Discusses strengths and limitations of CCD imaging technologies. (JRH)

Describes the behavior of a pulse during inversion of the pulse in a string when it reflects from a fixed end. Discusses the forces it exerts on the fixed end. (JRH)

Presents an experiment that demonstrates conservation of momentum and energy using a box on the ground moving backwards as it is struck by a projectile. Discusses lab calculations, setup, management, errors, and improvements. (JRH)

Describes methods used to investigate the working of 3-D glasses available with comic books. Reports that the glasses are produced using methods of binary optics and that a prism effect, as well as diffraction grating, is incorporated in the design. (JRH)

Presents a method to calculate the amount of high-level radioactive waste by taking into consideration the following factors: the fission process that yields the waste, identification of the waste, the energy required to run a 1-GWe plant for one year, and the uranium mass required to produce that energy. Briefly discusses waste disposal and…

Describes the working of an exhibit in the Ann Arbor Hands-On Museum in which separated water drops from two nozzles collide to make interesting shapes. Discusses the calculation of the vibration frequency after the drop breaks away from the nozzle and the effect of drop size and surface tension on this frequency. (JRH)

Presents an experiment to study the acceleration of a cart moving up and down an inclined plane. Demonstrates how multitiming and the study of the movement in both directions allows the determination of the component of gravitational force along an inclined plane without any assumptions about friction.
