The purpose of this research was to design, create a prototype, and evaluate an Educational Data Acquisition System (EDAS) for use in secondary school science laboratories. The prototype of EDAS consisted of a microcomputer, data acquisition interface, sensors, software, and documentation. It provided the teacher and students with a…

In a 16-year study involving more than 4,800 students, fewer than 2% of students were caught cheating in introductory science classes. The most common type of cheating was plagiarism in lab reports (50% of incidents), followed by altering exams (41%) and submitting falsified lab data (9%). Cheating occurred among students earning all grades in the…

Discusses some of the most important structural features found in modern chemical laboratories, including building shapes, floor plans, and window utilization. (MLH)

This book is intended as a guide for people who are planning chemistry and physics research laboratories. It deals with the importance of effective communication between client and architect, the value of preliminary planning, and the role of the project officer. It also discusses the size and layout of individual laboratories, the design of…

Seven-slide series produced by the Diafilm Studio are discussed as they are used as demonstration material for teaching students detailed familiarity with the morphology of the plants in given families and with the variety of their representatives. (Author/ND)

This inexpensive, effective chemiluminescence demonstration requires minimal preparation. It is based on the oxidation of oxalyl chloride by hydrogen peroxide in the presence of an appropriate fluorescent sensitizer. The reaction mechanism is not completely understood. (BB)

Two specialized facilities to produce cells and cell components on a large scale for scientific research have recently been established by the National Science Foundation. (BB)

This symposium focused on the question: can colleges afford to continue offering high quality laboratory instruction at the undergraduate level. (Author/BB)

This session focused on the types of chemistry courses taught in the high schools and the financial support of high school chemistry labs. (BB)

A kit is described for use in automation of routine chemical research procedures. The kit uses sensors to evaluate the state of the system, actuators which modify the adjustable parameters, and an organ of decision which uses the information from the sensors. (BB)

Describes a university level laboratory science course designed for visually handicapped students. (SL)

Discussed are causes of fires that occur in school science laboratories and ways of preventing them. (RH)

Describes how a traditional neurophysiology laboratory has been computerized and how students work with digitizing on-line data. Points out advantages of computerization, including the speed, accuracy, and reliability in the acquisition, reduction, and analysis of data. Also describes four generic computer programs tailored to the particular…

Rough economic and political readjustments which academic science face are discussed at a special meeting of the National Academy of Sciences. Ill-equipped laboratories, new federal regulations over waste disposal and animal care, and lack of funds have contributed to the problem of rebuilding and renovating academic laboratories. (DH)
