A Commodore-64 microcomputer was used to develop a system which is useful for a variety of teaching laboratory and real time control applications. Hardware and software requirements and examples of experimental work with the system are provided. (JN)

Presents the "Before Technology and After Technology" lab where students first complete a simple lab and graph the data by hand and then repeat the lab using graphing calculators. Enables students to see how technology can make data collecting, graphing, and analyzing more fun. (JRH)

Describes the use of storage oscilloscopes in five physics experiments, in lecture demonstrations, and in improved measurement techniques. (GS)

Describes an inquiry activity in which students explore the variables that influence the amount of time it takes a ball to roll down an inclined plane. Relates features of the activity to recommendations in the NCTM Standards. (MKR)

Describes an experiment to investigate chemical changes, pH, dissolved oxygen content, light intensity, and temperature in water containing aquatic plants. (MKR)

InSight, a series of 10 HyperCard stacks, provides optometry students with first-hand experience with a number of visual phenomena and a variety of experimental data acquisition and analysis techniques. Each stack contains background information on the experiment topic, instructions, references to the literature, and questions to be answered.…

Describes a hands-on lesson in magnetism designed to be used with upper elementary grade students. Emphasizes structured experiences which involve the student in measuring, data collecting, graphing, and extrapolating information. (TW)

Describes a data acquisition system developed for an undergraduate engineering students' instructional laboratory at Georgia Tech. Special emphasis is placed on the design of an A/D Converter Board used to measure the viscosity and temperature of motor oil. The Simons' BASIC Program Listing for the Commodore 64 microcomputer is appended. (LRW)

Presents two experiments in which students examine the effects of touching and shaking on plant growth in common bush beans. (MDH)

A description of the use of experiments used as a teaching strategy in mathematics is given. (MK)

Language teachers with little or no experience in conducting research are guided through the process of deciding what kind of classroom research to undertake, and how to organize and implement it. In question-and-answer format, four types of research are defined and explained separately: action, survey, correlational, and experimental studies. For…

Describes a take-home experiment in which students measure the diffusion of acid through acid-filled capillary tubes immersed into base solutions and vice versa. Students represent and analyze the effects of ambient temperature, molecular weight, and concentrations of the solutions on that movement. (MDH)

Describes a lesson in which fifth graders made observations of candles. Discusses the progress of the lesson and the necessity of instructing students in what and how to watch and measure. Stresses that this can be easily accomplished inexpensively with imagination. (CW)

Use of motion pictures and videotape recordings to analyze animal behavior is described. Indicates that accuracy/amount of data available is greatly increased and that simultaneous behaviors of different animals can be studied or individual behavior patterns increased/decreased, providing observers with temporal perceptions similar to the animals…
