Describes: (1) laboratory information science in the clinical chemistry curriculum; (2) testing Boyle's Law, a context for statistical methods in undergraduate laboratories; (3) acquiring chemical concepts using microcomputers as tutees; and (4) using Data Interchange Format files for Apple microcomputers. Includes feedback from a previous article…

Seven graduate students in a seminar on classroom computing received instruction in LOGO programming. Programming protocols were collected periodically and examined for errors and misconceptions; in-depth interviews were conducted in order to understand specific misconceptions better. As novice students transit from instruction to experience in…

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.

The discussions of the theme group on Technology and Cognitive Development at the Fifth International Congress on Mathematical Education are summarized. How computers can be used to engage students actively, to promote problem-solving skills, and to achieve better understanding is discussed. (MNS)

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)

Investigated were the effects of programing instruction with BASIC on mathematical thinking skills and concept development in grade six. Posttests assessed programing ability, generalization, and understanding of variables. Observations and interviews were also used. The groups having programing instruction scored significantly higher than the…

Shortcomings of current curricula for geometry in the elementary school are discussed. The use of the computer programing language Logo to develop geometric ideas is described, with supporting research. (MNS)
