Describes a versatile electric circuit, a simple and inexpensive vibration generator, and digital electronics demonstrations (with light bulbs) using a microcomputer. Also discusses bimetallic strips and their use as thermostats and the electrical resistance and resistivity of metals. (JN)

Describes eight steps in producing computer-assisted-instruction materials. They include selecting a topic, selecting approach to the topic, researching the topic, obtaining a programmer, writing problem definition, soliciting evaluation, field testing, preparing documentation, and monitoring efforts during program production. Also describes a…

Examines the need for a science of toxicology and training at both the undergraduate and graduate levels in response to legislation controlling drugs, food additives and toxic substances in the work environment, and concern about effects on man. Stresses need for putting toxicology on a scientific base with adequate funding. (JM)

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)

Indicates that present curricula are not preparing citizens to deal with critical social issues, in particular, those related to the environment, energy, food supply, and population problems. Offers 10 suggestions to help remedy the situation. (JN)

Describes a computerized method to test error analysis that helps motivate introductory physics students to learn the topic. The computer generates a test consisting of four topics from a list of 10 that students should know. Numerical data within realistic ranges are also generated. (JN)

Describes a coriolis simulator which uses a carbon paper trace technique and a simple specific-heat apparatus, emphasizing instructional considerations. Also indicates that a variac and an ordinary electric drill can be used to wind coil if a lathe or coil winder are unavailable. (JN)

A modified Winkler method for determining dissolved oxygen in water is described. The method does not require use of a burette or starch indicator, is simple and inexpensive and can be used in the field or laboratory. Reagents/apparatus needed and specific procedures are included. (JN)

Described is the history and use of computers in all phases of liberal arts education at Dartmouth College. Included are surveys of computer use by students, by instructors, and as an integral part of courses. (SL)

Like a spirited idea exchange among experienced professors, "Teaching Tips: Innovations in Undergraduate Science Instruction" brings the best thinking from campuses nationwide about how to engage undergraduate science students. Published to commemorate the 25th anniversary of the founding of the Society for College Science Teachers (SCST), "Tips"…

Influenced by the project entitled "Strategic Programs for Innovations in Undergraduate Physics", this document is intended to guide a physics department in initial, or mid-stream evaluation of a program of undergraduate physics education. The original Guidelines were developed by the American Association of Physics Teachers (AAPT) in 1986. The…

The is the first report from a study of a structured active learning approach to an analytical chemistry course. The purpose of the study is to assess the longitudinal outcomes of this approach and to provide feedback to curriculum developers about the effects of the changes being made in the chemistry curriculum. The data, collected from a cohort…

This paper reports on a unique assessment of a structured active learning approach to a freshman chemistry course. Faculty members (N=25) from 11 departments outside the chemistry department served as assessors interviewing approximately 200 students from the experimental and a comparison version of the course. The experimental section of the…

Students set in their ways are usually reluctant, as a general rule, to deal with open-ended investigative scenarios. In order to acquaint the student with the physical method and philosophical thought process of the discipline, the tone of the course must be set early on. The present study was conducted to develop scenarios and microbial model…

Discusses different kinds of material presentation in the teaching of electromagnetism at the university level, including three "classical" approaches and the Keller personalized proctorial system. Indicates that a general introduction to generators and motors may be useful in an electromagnetism course. (CC)
