Describes the activities of nine-year-old students during a six-week session designed to introduce them to computers and to the LOGO programming languages. Sample programs written by the students are included. Indicates that these students needed very little instruction or even assistance. (JN)

Discusses what can be done with a LOGO turtle robot, how it is different from doing LOGO with the computer-screen turtle, and the educational value of the device. Sample programs are provided, including one in which the robot turtle can be commanded to react to meeting an obstacle. (JN)

Microcomputer-based laboratories (MBLs) refer to a laboratory where a microcomputer gathers and displays data directly from the environment. Program listings for a response timer (using game paddles) to illustrate the nature of MBLs are presented. (JN)

Points out that the effectiveness of microcomputer-based laboratory (MBL) activities will be examined. Also indicates that a study is being conducted to assess children's and college students' mental models of heat and temperature and to determine how these models change when students learn about heat through MBLs. (JN)

Bank Street Laboratory (a set of hardware/software tools for measuring temperature, light, and sound) consists of a board that plugs into Apple microcomputers, cabling, software, and six probes. Discusses the laboratory's hardware, including the analog-to-digital converter, multiplier chip, and modular connectors. Circuit diagrams of components…

Discusses the use of the Bank Street Laboratory sound probe in activities focusing on various aspects of sound. Also examines what students were learning during the activities (such as students understanding what is meant by the pitch of a tone). (JN)

Describes "Experiments in Chemistry," in which experiments are performed using software and hardware interfaced to the Apple microcomputer's game paddle port. Experiments include temperature, pH electrode, and EMF (cell potential determinations, oxidation-reduction titrations, and precipitation titrations) investigations. (JN)

Reviews software packages used in microcomputer-based laboratory (MBL) experiments. They include programs for a precision timer, frequency meter, heat and light experiments, sound experiments, spectrum analysis, biofeedback analysis, and others. Reviews include a brief description, source, current cost, and equipment requirements. (JN)
