1] Tips for Do-it-Yourselfers

           Many of you who already own Mathwright Author 2000, or have ordered the Mathwright: My Way CD  at our online BookStore may be interested in some authoring tips that can get you started creating your own Teaching/Learning environments. 

          After you step through the tutorial, you will have created several books that will illustrate the wide variety of options open to you, but you may still be uncertain where to start.  Perhaps the most important decision to make before writing a WorkBook is this:  What story do you want to tell? 

          Your story will have two components.  There will be the screen design, that is, the appearance and placement of objects (graph windows, displayed mathematical formulas, with pictures and text, pushbuttons, textfields, checkboxes, wallpaper, hotspots, and so on) on the individual pages. 

And there will be the dynamic interactions.  These will be the scripted scenarios that will give your reader the opportunity to explore and ask questions as she reads your story.  The latter might simply be textfields where she enters a function definition or variable value, palettes where she chooses colors for drawing graphs or other sorts of pictures, matrix windows where she enters exact or floating point values in a matrix, or graph windows, where she selects a point or drags an object to its starting position. 

Interactions of this sort must be scripted, so that the system makes the appropriate response.   These scripts, written in MathScript, are what distinguish Mathwright from all other programs.  They give each WorkBook its dynamic character.   Now, where do these scripts come from?  

Well, our first tip is this: 

A] Use or modify scripts that others have already written in Mathwright Library WorkBooks.  You may already know of WorkBooks that do what you want, but if you do not, then just write to us at the Library, telling us what you have in mind, and we will suggest WorkBooks or individual scripts that can help you.  After a while, you will be comfortable writing your own from scratch.  You may be surprised how many ideas for interactions authors have contributed in the last 5 years.

And what about screen/WorkBook design?  Often, the organization of a WorkBook, its navigation from page to page, whether it includes audio or video cues, the choice of colors, pictures (wallpaper) and other decorations make a large difference to the reader.  It is important that she not get lost.  So a technique that brings her back to a “Home Page” such as the one used by Mike Pepe in Parametric Curves may be what you want.  Or you may prefer a linear sequence through the WorkBook as Jim Swift does in Periodic Functions.  Another approach is to develop a navigation tree organized by topics as Samad Mortabit did in his Discrete Dynamics.  Our next hint is this:

B] You may use a prior WorkBook as a model for your navigation and screen design.  Simply replace the content with your own, but keep the page structure.  Again, just write to us at the Library for ideas.

How large can a WorkBook be?  There are really no limits.  The Gravitation CD is a 55-page WorkBook, but much longer WorkBooks are possible, depending on your content.   And concerning content, our computer algebra system (and its companion Expert Systems) can support the usual tasks: symbolic differentiation, simplification of expressions, solution of equations and even exact rational complex arithmetic and abstract algebra (See for example: Cubic Equations, or better, the Lava Cardano WorkBook.)   But they surprisingly do the most good behind the scenes, checking for equivalent forms of correct answers as in Quadratic Functions or Work Problems.  

C] For exact rational algebra in your WorBook, just place: “load algebra” in your WorkBook Script.

Another powerful technique for helping students visualize processes and constructions is sprite animation.  Sprites are little graphical objects that move around in a window and illustrate various dynamics, such as a Model Solar System,  gradient dynamics, Logo graphics, elastic collisions (pool), or a Lunar Lander, for example. 

D]  You may find the sprites you want in the directories of Library WorkBooks.  Just copy them to your own directory, and they will be ready to import and use.  You may also design your own Sprites in Mathwright itself, or in any paint program that makes bitmaps. 

Finally, for now, we explain how you make your WorkBooks available to your readers.  When you create a WorkBook in Mathwright Author 2000 (which is also supplied on the Mathwright: My Way CD) then if you save it as an .imt file, anyone who has the Mathwright Library Player on his machine can read it directly.  Since the Library Player is freely downloadable over the web, you may assume your students have it.  Or, if you want your students to have access to it in a laboratory classroom, then you may install it from the  Mathwright: My Way CD.

E]  You may make your WorkBooks available to students simply by placing your WorkBook directory where they can read it using Mathwright Library Player.  There is no need for Webapp.  They simply open Mathwright Library Player and browse for your WorkBook file.  These WorkBooks can of course also be delivered over the web, as long as the student has the Library Player on his machine.  In this way, you may easily support your web course with interactive content.  They may even download mwl.exe from your website if you prefer.

          Most of our authors are college or university teachers.  We all know that the most important stages in a student’s mathematical development are met long before she enters college.  Perhaps the greatest challenge to educational technology today is to use it effectively to help young learners form clear ideas about mathematical constructions, models, and conventions. 

          We believe that, while “drill and practice” has a role to play, it is not the most promising role for computer learning environments.  Most of us know how engaged our children can be in playful game-like environments in which they willingly lose themselves, and accept the rules of the game.  These games (such as Myst, or Super Mario Brothers) are virtual realities that somehow capture their imagination…and their attention.  Imagine how powerful a learning environment would be if we could capture their attention in this way with environments in which they solved problems, and along the way, learned about measurement, and geometry, and about arithmetic, and algebra. 

          WorkBooks like Lemonade Stand and Roam (which were written by college students) are a first step in the direction of exploring some of the real potential of this new medium.  Other books like Heron’s Formula, or Boats attempt the same thing at a precollege level.

In an effort to interest Precollege classroom teachers, Home Schoolers, and Students to try their hand at authoring, for the next few months, we will be offering the Mathwright: My Way CD and Mathwright Author 2000 at a sharp discount for those groups.  The price of Mathwright: My Way is now $150.00 to anyone in the above categories, and the price of Mathwright Author 2000 is $100.00. 

We hope that many of our new authors will remember the Library and will contribute some of their work in the future so that it can be available to the general public.
