According to its publishers in the USA, WebEQ Developers Suite, Version 3, a significant upgrading from version 2.5, is "a collection of tools for putting dynamic math on the Web. The Developers Suite contains three programs, two applets, templates, sample scripts and extensive documentation. By using the programs and applets in different combinations, it is possible to create a wide variety of math and science related documents and interactive Web sites."

This review is written from my standpoint as a fulltime teacher in an English comprehensive school, and part-time web developer. (Don't ask where that part-time comes from!). It is being written over a number of weeks rather than all at once.

The entire 8.14 MB of the product is available for download from the MathType website. Once downloaded, a setup program creates all the files required and (if you request it) puts icons for a documentation file (HTML format), Editor, Publisher and uninstaller on your desktop. The documentation file is essential reading and is comprehensive, giving immediate access to introductory descriptions of the programs and applets and crash courses in "MathML" and "WebTeX", which are two methods of scripting mathematical symbols so that they appear correctly on-screen. The amount of information provided is indeed daunting, and in order for this review to avoid being little more than a summary of that documentation, I will base it on a number of key objectives.

Figure 1

Of course, if you are reading this now on the Internet, the problem has clearly been solved already. I did it by using MathType 5 to both create this statement and convert it to a "gif" image file. But can I do the same thing just as easily using the WebEQ editor? On my first attempt, I loaded the editor and began using the templates. I could not find the symbol for infinity, and when I tried to extend the toolbar to include extra symbols, WebEQ crashed! A second attempt was more successful and I was able to create the statement and save it in "jpeg" format:

WebEQ Editor also allows you to Save As HTML Applet. Guessing what this was about I followed the prompts and created a file of HTML. This file has been pasted below:

Figure 3

Figure 3 shows the output from a WebEQ applet, based on MathML coding. You may notice slight differences in appearance between the above three figures, which may or may not bother you. The "stretchy" brackets in Fig. 2 and 3 can in fact be tweaked by using WebEQ to make them more like those in Fig.1. You can go on to adjust in small detail many aspects of the look of these mathematical expressions. This may not be necessary for most mathematics teachers but could be very useful if preparing a precise document for print publication. As Figure 3 is not a graphic image but the outcome of some MathML coding, this coding can be edited within the HTML page to change the mathematical statement to something else. Figure 4 shows a possible outcome. In fact the expression in Figure 4 has been produced by WebTex instead, also shown, which I find a fair more teacher friendly coding system.

Figure 4

WebTex coding: \int_{-\infty}^{Q1}f(x) \mathop{dx}=\frac{1}{4}

It may be apparent to you by now that this product is not for the faint-hearted! To summarise this section, if you want to produce mathematical equations for display within HTML pages, and MathType is not available, then WebEQ supplies two methods of doing so - either as a static image or as code which can then be edited.

Objective 2: I want to produce interactive mathematical equations
Not satisfied with obtaining mathematics that looks right, I want to be able to do something with it. The WebEQ programs and Java applets do provide ways of adding interactivity such as various "mouseover" actions. A knowledge of JavaScript will be essential here to do anything more adventurous than the examples included in the Developer's suite.
