Discussed is a program created to serve as an instructional tool for teaching basin analysis. Described is the use of the program for interpreting plots resulting from backstripping methods. Included in the discussion are implementation, applications and availability of the "Subside!" program. (CW)

Suggested public relations activities for school libraries are presented in nine articles. Some of the activities described include the publication of newsletters and filmdisks using microcomputer software, a celebrity letter campaign, and planned communication with school board members. Resources for further ideas and guidelines are provided.…

Provides a program listing in True BASIC which constructs several kinds of matrices: (1) matrices with integral entries that have inverses that have integral entries; (2) matrices with integral entries that have inverses that are rational numbers with reasonable denominators; and (3) matrices with integral entries and prescribed integer…

Background information, data input, data analysis, and advantages of using this method with this software are discussed. A flowchart of the event-trapping program structure and a printout of the program are included. (CW)

Describes a laboratory experiment using AMPAC (a computer program) in conjunction with infrared spectroscopy. The experimental procedure and a list of questions for discussion are provided. Typical data are presented. (YP)

Examines current use of computers by historians and teachers of history. Attempts to predict extent of their use in next decade. Focuses on the use of four types of computer programs: word processors; spreadsheets and statistical packages; database management programs; and simulations. States that the computer is a tool historians can use to make…

Presents an overview of three ways that the computer can bridge the gap between reading and writing instruction: (1) word processing in the Language Experience Approach; (2) software to combine text and graphics; and (3) software to facilitate interactive reading and writing experiences. (MG)

A small school system can plan and install an effective computer system by developing a comprehensive plan; involving the personnel who will use the system; relying on vendors with proven records; and recognizing that training is an ongoing process. (MLF)

Provides some basic guidelines for converting a card catalog to a computerized catalog in school libraries. The advantages of using the MARC format are discussed, and three conversion methods (on site, records created by the vendor off site, and full vendor conversion off site) are compared in terms of the work involved, costs, and time. (CLB)

Describes a prototype interactive science catalog for children that will have three interfaces: a subject-oriented browsing search, a search tied directly to science simulations, and an author/title/subject keyword searchable interface. Research plans include examinations of children's abilities to formulate and implement searchable queries and…

Surveys the current state of computer applications in six areas of library work: circulation control; descriptive cataloging; catalog maintenance and production; reference services; acquisitions; and serials control. Motives for automation are discussed, and examples of representative vendors, products, and services are given. (15 references) (LRW)

Discusses the increasing need for electrical, electronic, and computer engineers; and scientists. Provides current status of the computer industry and average salaries. Considers computer chip manufacture and the current chip shortage. (MVL)

Presents a computer program for use in teaching ion speciation in soil solutions. Provides information on the structure of the program, execution, and software specifications. The program estimates concentrations of ion pairs, hydrolytic species, metal-organic complexes, and free ions in solutions. (Author/RT)

Discusses a television program, "Mathematical Eye," for children aged 11-13. Describes sample programs, style, and supplemental materials, such as a teacher's note, investigations pack, book, and software. Lists the titles of 10 programs. (YP)

States that quantitative modelling allows teachers to concentrate more on qualitative understanding. Suggests the main benefits as (1) repetitive calculations are reduced allowing greater attention to be focused on underlying models; (2) more "what if" models can be tested; and (3) a wider variety of data can be used to test models.
