Describes the necessary procedures and equipment needed to modify the American Association of Physics Teachers' (AAPT) pocket calculator timer so that it can be controlled photoelectrically. (SL)

Describes the graphing calculator as a new graphical approach to standard physics problems. Presents a collision problem to illustrate its use. (JRH)

Presents a series of simple activities involving generalized two-dimensional motion topics to prepare students to study projectile motion. Uses a pair of motion detectors, each connected to a calculator-based-laboratory (CBL) unit interfaced with a standard graphics calculator, to explore two-dimensional motion. (JRH)

Presents four examples of physics problems that can be solved with a graphing calculator. Problems included deal with motion, harmonic oscillations, sound waves, and blackbody radiation. (JRH)

Presents Texas Instruments' new Calculator-Based Laboratory (CBL), a hand-held device that connects to a graphing calculator, as a tool to make sophisticated measurements outside the classroom laboratory. Describes activities that use the CBL to make measurements in motion studies. (JRH)

Describes the use of the TI-82 graphics calculator as an intermediate step in introducing computers to the high-school physics lab. Discusses linking the calculator with other machines so that students can save data, enter programs on a computer and later download to the calculator, and transfer graphs to a computer for printing. (JRH)

Describes the use of the Texas Instruments' calculator-based laboratory (CBL) and Vernier accelerometer for measuring the vector sum of the gravitational field and the acceleration of amusement park rides. (JRH)
