Salaries and demand for scientists and engineers are described. Comparisons of chemists and other scientists are provided. Resources for career planning in science and engineering are listed. (CW)

Computer assisted instruction (CAI) as an optional enrichment versus required component is described. Discussed are making CAI an integral component of freshman chemistry, program requirements, need for user modification of programs, staff and facilities, mode of operation, student evaluation, and effect on student performance. (KR)

Included are three demonstrations that include the phase change of ice when under pressure, viscoelasticity and colloid systems, and flame tests for metal ions. The materials, procedures, probable results, and applications to real life situations are included. (KR)

Presented is an experiment where the concentrations of three metal ions in a solution are simultaneously determined by ultraviolet-vis spectroscopy. Availability of the computer program used for statistically analyzing data using a multivariate linear regression is listed. (KR)

Explains the importance of introductory science courses and presents characteristics of exemplary courses. (PR)

Describes a computer program to teach the concepts that underpin genetic mapping using a three-point test cross. The program is used in a sophomore-level course for biology majors that presents a rigorous introduction to genetics. (PR)

Appreciation for the images used in biology can be deepened through iconographical studies (the study of the subject matter and meaning of works of art.) Describes iconographical studies of organisms and ideas beginning with T. H. Clarke's analysis of the iconography used for the rhinoceros. (PR)

Describes a field trip to Costa Rica by college students and an instructor in a tropical ecology course. (PR)

Describes an interesting field experiment examining the distribution and diversity of a single community using lichens and the animals living in them. Combining field experience and laboratory work reveals not only the biology of some unusual organisms, but also community ecology and diversity. (PR)

Presents a chromosome map for 19 known chromosomes in human genetics. Describes the characteristics attributed to the genetic codes for each of the chromosomes and discusses the teaching applications of the chromosome map. (MDH)

Discusses misconceptions and outdated models appearing in biology textbooks for concepts involving bioenergetics and chemical reactions; adenosine triphosphate (ATP) as the energy currency of cells; the myth of high energy phosphate bonds; structural properties of ATP; ATP production from respiration and fermentation; ATP as an energy storage…

Describes two curriculum approaches used at a college as an alternative to traditional introductory science-survey courses. The first course is entitled "Nature of Science" and the second is "Current Research." (PR)

Reports on a questionnaire completed by 73 universities. Results indicate that laboratory instruction is part of almost all introductory biology classes. The majority (62%) of these institutions offer separate biology courses for majors and nonmajors. There is renewed interest in investigative types of laboratories. Most laboratory instruction…

Describes experiences of the Computers in Teaching Initiatives (CTI) centers for chemistry and physics which provide support to academic staff in universities in the United Kingdom who are using communications and information technology. Topics include funding by the Teaching and Learning Technology Programme (TLTP); courseware development; and…

Describes the use of voicemail for a large class in general chemistry at McGill University (Canada) that used the Monomedium instruction system. Discusses what information is provided, the design of the course material, use statistics, evaluation by students, and the professor's perceptions. (Author/LRW)
