Have you ever been working on your computer and wanted to capture an image of the screen so that you could show your work to someone else, perhaps your students? When mathematics teachers create technologybased lessons, they often need to create professional-looking documents—such as handouts, tests, Web pages, distanceeducation course materials, and “Technology Tips” manuscripts—that include images from work done on a computer. In this month's “Technology Tips,” we share some inexpensive or free ways that enable you to capture and use images in your work. The techniques that we describe can capture images of anything that is displayed on your computer monitor. In this example, the screen captures that we demonstrate are of a statistical exploration of SAT data in the software application Fathom (available from Key Curriculum Press at www.keypress.com/ fathom). The SAT data used can be found at the College Board's Web site (www.collegeboard.com/about/news_ info/cbsenior/yr2003/html/links.html).

“TECHNOLOGY TIPS” in the September 2003 issue of the Mathematics Teacher demonstrated how to create a table of values and graph of a function in Excel where the function rule is based on parameters that can be changed. It showed how to use Excel to create an exploration of the parameters of a linear function with rule f (x) = ax + b. This month, we demonstrate how to add interactivity to parameter explorations of linear functions with Excel and The Geometer's Sketchpad (Jackiw 2001). We show how to insert sliders in Excel to control the values of the parameters and show how to create a similar investigation using Version 4 of The Geometer's Sketchpad. The “Surfing Note” this month is www.ExploreMath.com. This Web site includes a variety of interactive activities, lesson plans, and free course Web pages for teachers.

This final column for the 2002–2003 SCHOOL year completes the “Mapping Diagrams” tip from April 2003. I hope that this treatment, as well as the Web pages mentioned, spurs some fresh interest in this fascinating parallel-axes alternative for graphing functions. Readers should note that the programs Maplite and Mapper are available from Henri Picciotto's Web site at http//:www.picciotto.org/math-ed/func-diag/software. Picciotto's site was highlighted in last month's “Surfing Note.”

This chapter is the result of a two years effort to design a template aiming at standardizing, as much as such a task is feasible, the evaluation of Web sites. It is the product of a few publications in international conferences and journals. A thorough review of the international literature on the subject led the authors to conclude there is a very large number of opinions, thoughts and criteria from different professionals involved, directly or indirectly, with the process of designing a good Web site. To make matters even more complicated there are a number of different terms used by various scholars, scientists and professionals around the world that often refer to similar, if not the same, attributes of a Web site. However, it seems that all these differences could boil down to a systematic approach, here called evaluation template, of 53 points that the design strategies of the Web sites should be checked against. This template was tested on a significant number (232) of Web sites of Greek companies and proved it can be used to evaluate the quality of Web sites not only by technology experts but by non-experts alike. The evaluation template, suggested here, is by no means the solution to the problem of standardizing the process of evaluating a Web site but looking at other work done on the subject worldwide it is a step ahead.

The aim of this contribution is to show how the information, concerning the order in which the pages of a Web site are visited, can be profitably used to predict the visit behaviour at the site. Usually every click corresponds to the visualization of a Web page. Thus, a Web clickstream defines the sequence of the Web pages requested by a user. Such a sequence identifies a user session.

Search engines use crawlers to traverse the Web in order to download web pages and build their indexes. Maintaining these indexes up-to-date is an essential task to ensure the quality of search results. However, changes in web pages are unpredictable. Identifying the moment when a web page changes as soon as possible and with minimal computational cost is a major challenge. In this article we present the Web Change Detection system that, in a best case scenario, is capable to detect, almost in real time, when a web page changes. In a worst case scenario, it will require, on average, 12 minutes to detect a change on a low PageRank web site and about one minute on a web site with high PageRank. Meanwhile, current search engines require more than a day, on average, to detect a modification in a web page (in both cases).

Making Math Happen: An Interactive, Technology-Rich Approach

Interactive Technology

Many mathematics teachers hold the tantalizing conviction that if their students could only just see mathematics happen, make mathematics happen, they would get it. When students do mathematics interactively, they are able to fiddle with parameters, watch the effect of making those changes, and begin to construct their own mental models. Computers, with well-designed software, can both remove the tedium and redundancy of calculation and provide dynamic visuals, lending themselves to the task of giving students such opportunities. The Shodor Education Foundation's Interactivate provides such software, freely available, on its Web site.

Online courses present a new element to learners in college courses. Interfaces (web pages) take the place of an instructor as the primary information delivery system. In other words, a student’s learning experience is now tied to the quality of a course’s human- computer interaction. One emerging method of online course delivery is an adaptive course that tailors to individual students needs, abilities, or preferences. There has been much work done on the algorithms that allow the course to adapt to individual students, but there seems to be a lack of research into the usability of these interfaces and how their quality affects student performance and satisfaction. This paper presents some of the data that was collected in a larger, grant-supported project and establishes relationships between usability metrics (ease of use and perceived usefulness) and student satisfaction and outcome measures in adaptive-online courses.

Archaeological Knowledge

Unlike many regional archaeologies the study of Egypt has always had widespread appeal, from archaeologists to Afrocentrists, orientalists to occultists. According to one web-site, ‘Egypt dominates the history of the world.’ This ever-popular fascination has spilled over into the electronic media since the inception of the Internet. Thus, Egypt proves to be a telling casestudyin net politics and potentialities. Simply typing the word ‘Egypt’ into a Web searcher elicits over 1 million sites, and the content of that material runs the gamut from scholarly resources closely matching those known in print to fringe sites and sci-fi web pages. This makes electronic Egypt an intellectual and ethical minefield for the uninitiated, especially as there proves often little to differentiate between this panoply of sites in terms of presentation and professionality. It palpably illustrates the homogenization of knowledge on the net and prompts us to consider the construction of archaeology and archaeological knowledges.

With the growing popularity of the Internet as a communication medium, National Collegiate Athletic Association (NCAA) athletic departments have turned to their Web sites to build interest in their product among consumers. As sites continue to develop traffic, it is important to examine the coverage being provided on the home Web pages to determine whether equitable coverage is being allocated to men’s and women’s nonrevenue sport teams. The current research featured a content analysis of NCAA divisional Web-site coverage during an academic school year. From a broad perspective, the results indicated that only Division III provided equitable gender and individual team coverage allocations on its home Web pages. In contrast, the data also supported the notion that Division I athletic programs (Football Bowl Subdivision [FBS] and Football Championship Subdivision [FCS]) provided significantly more coverage to men’s baseball, men’s basketball, and men’s football than nonrevenue-sport teams. The FBS and FCS coverage inequalities are discussed in depth in the article.
