New Product Focus 
The TI-80 Graphing Calculator: 
TI's most affordable graphing tool. 
 
 
The TI-80 responds to teachers' requests for a low-cost graphing calculator that is appropriate for middle school mathematics, Prealgebra and Algebra I. 
To meet the needs of high school and university educators teaching algebra, as well as middle school educators, the TI-80 combines many of the graphing and user interface features of the popular TI-82 with the fraction features of the popular TI Math Explorer.  
Like the TI-82, the TI-80 offers graphing, tables and data analysis capability. The TI-80s pull-down menus allow easy access to advanced functions without cluttering the keyboard, and keys are functionally zoned to simplify calculating.  
Graphing features of the TI-80 let students: 
 	Define, save, graph and analyze up to four rectangular functions at once. 
 	Automatically plot selected functions in the display with one key press. 
 	Use the cursor keys to trace along any of the graphed functions, displaying both X and Y 	coordinate values simultaneously. 
 	Save, graph, and analyze up to three parametric equations using trace and zoom features.  
 	Shading features show intersections of inequalities using vertical, horizontal, and diagonal 	shading patterns.  
	Enhanced data analysis features include the capability to: 
 	Define and store up to three statistical representations using scatter-plots, box-and-whisker plots, 	xy-lines and histograms. 
 	Perform linear, logarithmic, exponential, power, and quadratic regressions. 
 	Deduce probability using random-number generators, permutations, combinations and factorials. 
Like the Math Explorer, the TI-80 allows students to enter fractions and perform the full range of arithmetic operations such as multiplying, dividing, adding and subtracting, and finding square roots.  
In working with fractions, students can: 
Perform manipulations and operations. 
Convert between fractions, mixed numbers and decimals. 
 Simplify fractions to lowest terms, either automatically or step-by-step. 
A TI-80 ViewScreen[tm] is available to enhance classroom instruction. In fact, a special TI-80 ViewScreen version of the calculator is available separately. It is compatible with the current LCD ViewScreen panel for  
the TI-81 and TI-82. The TI-80 ViewScreen calculator is also compatible with the TI-GRAPH LINK[tm] cable through its link port (cable available separately). This allows printing of the screens for use in handouts or other documents. Macintosh(r), Microsoft(r)Windows(r)and MS-DOS(r)software is included with each TI-80 ViewScreen calculator. 
The TI-80 is available now and is supported by TI's Workshop Loan and Volume Purchase Programs.

Cabri and CBL Updates 
Cabri Geometry II[tm] for  
MS-DOS(r) 
Cabri Geometry II from Texas Instruments, the interactive learning tool for geometry students, will be available for MS-DOS (version 3.1 or better) in the second quarter of 1995. Cabri is currently available for Macintosh (System 6.0 or better). 
Because Cabri Geometry II includes Euclidean, transformational, and analytic geometry, it is the most comprehensive and intuitive geometry software on the market. 
Cabri Geometry II supports integrated mathematics by going beyond geometry to geometric visualization of algebraic problems. Cabri can display the equations of basic geometric objects. You'll even find vectors and conics. 
Yet, with all this power, Cabri is easy to learn and easy to use. Students click with a mouse and select from a toolbar to construct geometric objects. Customizable menus let you control what appears on the menus. TI even supports Cabri with reproducible student activities and workshops. 
For a free demo disk, call 1-800-TI-CARES. To purchase Cabri Geometry II, contact your area instructional products dealer (see page 16), or call 1-800-TI-CARES. 
 
 
 
 
 
 
 
 
 
 
 
 
Try It In Your Classroom   New Activity Book for the CBL System 
Exploring Physics and Math With the CBL System offers 48 lab activities using the  
TI-82 and the CBL System. Many of the activities are suitable for teaching math concepts as well.  
(See article on page 8.) 
The Calculator-Based Laboratory (CBL) System lets students gather real-world data, retrieve it directly into their TI-82 or TI-85*, and then generate graphs and analyze results anytime or anywhere. 
		Handheld and battery operated 
		I/O port for linking with a TI-82  
		or TI-85 
		3 probes for measuring temperature, light intensity, and voltage included 
		Measure motion, sound, pH, and more with appropriate probes (avail-					able separately) when used with an optional adapter

		Exchange ideas 
		Exchange programs and files 
Graph-TI, an electronic mail (e-mail) interest group, allows users of Texas Instruments graphing calculators to share ideas and solve problems together. It is provided by Texas Instruments in support of educators. Users of Graph-TI discuss:  
		Applications of graphing calculators in math, science, and engineering. 
		Sources of additional information. 
		Instructional and pedagogical issues using graphing calculators.  
Calc-TI, an interest group similar to Graph-TI, opened in April, 1994, to support the programming hobbyist with more technical information and discussions. 
Internet "mailing lists provide an easy way to send e-mail to other members of an interest group. The mail might be an idea, a question, or a response. Long discussions on a topic often take place, and all members can "listen to the e-mail conversation and benefit from it. TI Graphing Products Team members contribute answers to technical questions. 
Graph-TI is available to anyone with access to electronic mail on the Internet or connected networks. Most colleges and universities have this access, as do an increasing number of secondary schools. (Many teachers without e-mail have found a local college, university, or library to be cooperative.)

ViewScreen Light Box - an Overhead Alternative 
Many educators have shown interest in a portable, battery-operated light box used by  
Texas Instruments at various conferences around the country. The Tru-View Light Box by Logan, when used to backlight TI ViewScreens, provides educators (and us) with a convenient and effective way of demonstrating the calculator screen to small groups of students or educators.

First Use of Calculators in Classroom Communications CommunicationsCommunications 
 
The TI-85 Graphing Calculator is the first calculator to be used in two-way communication between the instructor and students. This is accomplished through an interactive networking technology developed by Better Education, Inc.  The newest version of the company's "Classtalk" system, designated "CCS-85," uses TI-85s and a Macintosh computer to provide two-way communications in any size classroom or lecture hall. 
Dr. Louis Abrahamson, President of Better Education, Inc., noted that the selection of a Texas Instruments calculator was no coincidence.  "Better Education is the developer of the first Classroom Communication System, and Texas Instruments is the leader in calculator technology.  The TI-85 is one of the few calculators on the market with fully-implemented communication capabilities, so it made sense to choose it as the first calculator to use with our new system." 
The first calculator-based Classtalk systems are being installed in lecture halls at the University of Massachusetts, Amherst, and the University of Cincinnati to provide interactive instruction in Chemistry, Mathematics, Physics, and Economics. Enhancements in 1995 include special analytical tools for math and algebra instruction. The system is easy to use and comes complete with all the hardware and software needed to install it.  Installation options include fixed-seat wiring or ceiling installation with pull-down cables. 
The combination of Classtalk and TI calculators brings an important new dimension to what is being called the "Classroom of the Future. The CCS-85 system will be available second quarter 1995 and orders are being accepted. For more information, contact:
