Shelley Limegrover January 22, 2011 OVERALL The fourth site I evaluated was the Physics Front. This site is intended as a resource for high school physics teachers. It contains links to sites containing lesson plans, activities, and labs searchable by topic and grade level. The site was very nicely organized and contained a lot useful information. CONTENT This site is made available by the American Association of Physics Teachers and is funded by the National Science Foundation. A list of contacts is provided. The site claims that the content is frequently reviewed and updated for accuracy. The bulk of the content on this page is links to other websites. However, the Physics Front is much more than a list of useful physics resources. All links are summarized in detail as to their subject matter, application, intended grade level, etc. Rather than having to fish through a never-ending list of links, the advanced search options make finding relevant material very easy. All links that I tested at random were functioning properly. DESIGN This site is very well designed. The layout and formatting is consistent on all pages. Navigation is simple with a menu bar accessible from all pages. There are no irrelevant graphics or advertisements. It is easy to scan the pages for pertinent information. The copyright date is clearly presented at the bottom of the all pages.

Shelley Limegrover January 22, 2011 OVERALL The third site I evaluated is the Physics 2000 site. The site explains general physics concepts in a dialog format using an imaginary cast of physics professors and students. One or more interactive simulations accompany all dialogs. The site is intended as a resource for high school and non-science college students that presents otherwise abstract material in a more comprehensible format. I found the presentation of material to be very creative, although the site itself seemed visually "busy" and awkward to navigate. CONTENT The authors of the site are clearly identified and include a physics professor, various science advisors as well as a high school physics advisor. The credentials of all authors and advisors are not provided, but the site claims to be funded by grants from the National Science Foundation, giving it some credibility. The dates of copyright and last revision are not readily apparent. However, the main page states that they are looking for sponsors to support continued operation. Recommendations for supported browsers are a few years out of date. The content itself does not seem adversely affected by lack of updates. All content links are functional as are all interactive applets that I tried at random. DESIGN Some pages of the site are designed better than others. The choice of colors and layout do not make information immediately visible. The navigation is not consistent across pages. The relevant content, however, is presented nicely once I get to it. This makes it worth a visit to the page. Interactive applets are provided wherever they are beneficial.

Shelley Limegrover January 22, 2011 OVERVIEW The second site I evaluated was phet.colorado.edu. This site contains interactive simulations of math and natural science concepts relevant to all grade levels including college. This site is intended primarily for Teachers. Besides science simulations, the site contains suggested classroom activities and lesson plans corresponding to the simulations. All content can be downloaded or run directly from the site. CONTENT The content and intended audience of the site is made immediately clear on the first page. More detailed information about the intent of the site as well as about the authors and sponsors is made available via a list of links at the bottom of the homepage. The information on the site is not immediately easy to understand. However, this is remedied by instructions and suggested uses of all the content on the page. The site also offers dates for teacher workshops so that they may learn how to apply the material. As I mentioned in the overview, this site is primarily for teachers. A student would not be able to navigate through the material effectively without guidance. DESIGN The homepage downloads quickly and is clear of distraction. A simple navigation bar is provided at the bottom of the page. No scrolling is necessary to see it. The copyright date is clearly identified though dates of last revision are not. There are no broken links and all material appears to be up-to-date. The format of all pages is consistent and a navigation bar is always present. The site was compatible with all three browsers that I had available to test. The simulations are neatly presented on a single page, searchable by subject matter or grade level. There are no unnecessary graphics or video files on other pages of the site.

Shelley Limegrover January 22, 2011 OVERVIEW The first site I evaluated was physicsclassroom.com. This site is intended for both students and teachers of physics at the high school and early college levels. The site is very comprehensive including everything from curriculum and worksheets to tutorials and simulations. I found this site so helpful and easy to navigate that I imagine I will be returning to it many times in the future. CONTENT As noted above, this site is very comprehensive. Information is easy to access including information about the author, who is a graduate of chemical engineering and now a high school physics teacher. The author claims to make frequent edits to the site, thought the dates of last revision are not apparent. As far as I can tell, the information appears up-to-date with current-day physics knowledge. All pages contain complete information and there are no broken links. DESIGN This page is very well designed. The author did an excellent job presenting a lot of information in a concise format. The navigation is easy to use and the layout of the pages is consistent. Portions of the site that may be problematic for the user are accompanied by a brief introduction and, when applicable, instructions (such as for the interactive portions of the site). Should any confusion arise, the author's contact information is available.
