How to Use These Programs Using SIRs, one may explore the behavior of chemical systems and conduct simulated experiments of one's own (or better still, the students') devising. One may ask, What do you think happens next? or What would happen if?, explore possibilities with the class, and then ask the computer to show what the chemicals actually do. The content and level of these SIRs are appropriate for introductory courses at high school or college. SIRs are not intended to replace laboratories or classroom demonstrations; instead they can enhance and extend live experiments and demonstrations. For example, use SIR Unknown to generate problems involving the titration of unknown acid or base (strong or weak, monofunctional or difunctional) to determine molecular weight of the unknown. Students are given the concentration of a standard solution and a sample titration curve and must decide how much unknown to use, determine the best indicator, and read a simulated burette. Anyone who teaches the topics listed for the nineteen SIRs in this issue will find that these programs enhance classroom presentations. Microwave Spectroscopy Tutor can be used both by the instructor as a lecture aid and by students as a laboratory simulation or homework exercise. It is suitable for use in physical chemistry and molecular spectroscopy courses. The program simulates a microwave (rotational) spectrometer, an instrument that very few universities have available for students, especially at the undergraduate level. Hardware and Software Requirements Programs in Series B of JCE: Software require an IBM PC-compatible microcomputer with 640K RAM, a hard disk, one floppy disk drive, and VGA or better graphics. DOS 5.0 or greater is required. In addition to these requirements, SIRs requires 4.5 MB of hard-disk space and a Microsoft compatible mouse. Effective use of SIRs requires a classroom projection device such as an overhead projector panel or a three-gun projector. A 486 or higher processor is recommended. SIRs will run on 286 or 386 computers but may be noticeably slower. Microwave Spectroscopy Tutor requires the DOS utility program GRAPHICS.COM in order to print. The program requires about 100 KB of hard disk space. |
