Provides demonstrations using digital display instruments of some of the mass and pH-related topics covered in first-year chemistry courses. (CP)

Explains the theory and laboratory construction procedures of a positive photoresist. (CP)

Describes a laboratory procedure which does not demand sophisticated equipment. (CP)

The energy levels of the free field, Coulomb potential, and the three-dimensional harmonic oscillator are found using the Dirac operator formalism by the construction of suitable ladder operators. The degeneracy of each level is also discussed. (Author/GA)

Discusses the need for engineering education to keep pace with and participate directly in the development of technology and society. (SL)

Reviews Mali's experiments in training engineers and high-level technical personnel. (SL)

The placement rate of PhD's in marine geology between 1967-1970 is reported. Of these graduates about 35 percent are listed on current university faculty in marine geology. (MR)

Reports results of a survey of entering freshmen to determine their characteristics and attitudes as they proceed through their first two years in engineering programs. (SL)

Presents the view that engineering is declining in the United States and provides recommendations for reversing the decline. (SL)

Discusses difficulties in determining the effectiveness of classroom teachers. (SL)

Describes the construction of an apparatus for demonstrating the center of percussion and pivot point of a ball being struck. (MLH)

Describes a one quarter introductory college physics course for nonscience majors which concentrates upon energy, energy systems, and relevant practical situations exemplifying energy laws. Results indicate the course is also suitable as a preparatory course for preprofessional students. (SL)

Reports research results of formal versus informal instruction effects on retention. Subjects were 70 undergraduates in first year physics (one control, one informal class, one formal class). A test conducted seven weeks after course completion showed significantly higher retention by the informal group. (SL)

Describes an introductory college science course for science majors and nonmajors. The course, team taught and interdisciplinary, stresses broad applications and topics of current interest. Presentations and instructors are changed regularly. The laboratory experiences include computer programming, are varied regularly, and allow student selection…

Considers perceived trends of lesser ability students entering introductory chemistry courses. (SL)
