Describes two spreadsheets for producing acid-base titration curves, one uses relatively simple cell formulae that can be written into the spreadsheet by inexperienced students and the second uses more complex formulae that are best written by the teacher. (JRH)

Defines the Internet and discusses the implications of an information society on K-12 education. Presents examples of Internet use that support technology-based learning activities for both students and teachers of K-12 classes. Information is provided for connecting to the Internet using commercial services. (JMV)

Points out that the notion of "concrete" is relative and argues the advantages of, and recommendations for, using computer manipulatives. (MKR)

Presents experiments that use Microcomputer Based Laboratory (MBL) techniques to enable freshmen physics students to investigate complex systems, such as nonlinear oscillators or coupled harmonic oscillators, at a level appropriate for an independent project. (JRH)

Presents a real-life example of mathematical modeling in which a medical company asks for help in solving a warehouse-inventory problem. Uses charts, graphs, and computers. (MKR)

Presents examples of what can be done with CD-ROMs to enhance learning about weather and climate. Topics include hurricanes and tropical storms, climatic studies with CD-ROM archives, and assessment. (JRH)

Presents a paper-folding method to develop a class repertoire of construction methods for the ellipse, hyperbola, and parabola using straws, rulers, dental floss, paper circles, and other household items. Uses the Geometer's Sketchpad software to complement the paper-folding process. (MKR)

Describes simple inexpensive modifications to existing equipment that facilitate the computerization of interference and diffraction experiments done in introductory laboratory courses. (JRH)

Describes computer conference courses in special and general relativity that use a text-based remote computer conference setting in which students receive assignments, exchange messages with other students and the instructor, participate in discussions, and submit answers to exercises. Discusses possible reasons why these courses have not worked…

Describes hardware that enables the use of an IBM PC microcomputer as a frequency meter or a counter by using the parallel printer port. Eliminates the 16-bit time-day counter through the use of an external time base that can be conveniently set depending on the desired frequency range. (JRH)

Discusses the World Wide Web, a system used to display and distribute information on the Internet through hypertext links. Topics include browsing software called Mosaic; Web resources for elementary and secondary education students and teachers; online educational resources; Web server sites; and creating a home page. (LRW)

Discusses the distinction between drawing and constructing in dynamic geometry environments. (MKR)

Argues that evaluating electronic versions of students' writing saves time and makes grading easier. Explains how the author uses custom-designed macros to provide comments and guidance to students with more elaboration than is possible by writing comments on the margins of the papers. (PA)

Describes the availability, installation, and use of the ZhonWen Disk Operating System (ZWDOS) to display, print, and transmit Chinese characters on conventional International Business Machines (IBM) personal computers and IBM-compatible machines. Also discussed is the use of ZWDOS to compose electronic mail messages, read newsgroups, and access…

Discusses the use of a Sutterlin computer font that can help teachers of German acquire a working knowledge of that arcane script by generating an unlimited number of neat and perfectly regular practice texts. The deciphering of Sutterlin printouts can also serve as a worthwhile supplementary activity in various advanced German courses. (MDM)
