Use of diagnostic testing (for mathematics skills) and multiple-choice, computer-graded homework in reducing dropout from general physics is discussed. Indicates that these strategies were successful without sacrificing academic or grading standards. Includes list of topics on the diagnostic math test and sample homework problem set (in…

A PASCAL graphics and instrument interface program for a Z80/S-100 based microcomputer was developed. The computer interfaces to a stopped-flow spectrophotometer replacing a storage oscilloscope and polaroid camera. Applications of this system are discussed, indicating that graphics and analog-to-digital boards have transformed the computer into…

Discusses ways computers are being used in condensed-matter physics by experimenters and theorists. Experimenters use them to control experiments and to gather and analyze data. Theorists use them for detailed predictions based on realistic models and for studies on systems not realizable in practice. (JN)

A complete listing of a projectile motion program for the Apple II microcomputer is provided. A discussion of this computer simulation and a table with variables used in the program (as well as their meanings) can be found in SE 533 596. (JN)

Background information, procedures, and results are provided for a series of graduate/undergraduate polymer experiments. These include synthesis of poly(methylmethacrylate), viscosity experiment (indicating large effect even small amounts of a polymer may have on solution properties), and measurement of weight-average molecular weight by light…

Provides background information, procedures, and results of an experiments designed to introduce undergraduates to the technique of steam distillation as a means of isolating thermally sensitive compounds. Chromatographic techniques (HPLC) and mass spectrometric analysis are used in the experiment which requires three laboratory periods. (JN)

Suggests that Genesis is not a scientific treatment of the earth's origin/age, but is a primitive religious history of Israel and a polemic against much of the theology of the Babylonian creation myth. Indicates that Genesis narrative and conclusions of science belong to different spheres of knowledge. Educational implications are addressed. (JM)

Discusses why, when and how microcomputer simulations of biological topics should be used in the classroom. Includes a five-step procedure for creating such simulations using population growth as an example to describe each step. Steps include topic/background material selection, writing program, and making support materials for the simulation.…

Traces the development of electrical engineering (EE) from its roots of academic physics in the 1890s to a discipline with its own priorities and departmental structure. Includes a description of the first EE course offered at the Massachusetts Institute of Technology (MIT). (JN)

Highlights "Graduate Student Survey" and "Survey of Physics and Astronomy Bachelor's Degree Recipients." Among findings reported are those indicating that many foreign students are not competing for jobs with American PhDs, more 1981/82 graduates (5 percent) received no job offers than 1980/81 graduates (3 percent). (JN)

Water striders are insects that walk and run on the surface of water. Discusses the morphology, physiology, and behavior of these insects. Includes diagrams of stages in the movement of a typical strider. (JN)

Lists: (1) educational uses of microcomputers; (2) goals of a microcomputer selection committee; and (3) goals to be achieved by students owning microcomputers. Discusses progress made by the selection committee, faculty development in computer literacy, current preparations being made for the arrival of the microcomputers, and computer uses in…

Discusses the importance of teaching the Bohr atom at both freshman and advanced levels. Focuses on the development of Bohr's ideas, derivation of the energies of the stationary states, and the Bohr atom in the chemistry curriculum. (SK)

The laboratory of an organic chemistry course for dietetics students is based on the learning cycle approach (exploration, invention-concept introduction, and concept application). The laboratory program is divided into four sections: lab techniques, compound types, reaction types, and reaction characteristics. (SK)

Describes a two-quarter, freshman honors laboratory course at the Ohio State University, including selection of students, nature of experiments, and safety precautions. Specific instructions are not given to students, who then run reactions under conditions they devise. (SK)
