http://www.merlot.org/merlot/viewComment.htm?id=283862
If used effectively, I think that this site is a really good tool for students who are at least taking an intermediate algebra class and higher math. I spent 45 minutes reviewing the materials, playing with the graph function tools and found it simple and easy to use. Content quality is good; the site offers concepts that are educationally significant because you get instant results. Students and teachers will benefit by the ease-of-use and visual concepts of graphs. Lastly, first-time users will find this a fun and simple way to understand graphs and how they are used.Comment for Function Grapher from Dawn Ruml

The material here provides important concepts in math. It does not appear to be very difficult to teach or learn. It teaches material that will be needed in future math classes. The site has effective graphics and multimedia. The feedback is immediate.Technical Remarks: To me the material seemed matematically correct.The material follows standard mathematical notation and conventions.Comment for Function Grapher from Sarah Cady

Function Grapher is very easy to use. Although it may be too simple for graphing more complicated equations, it works extremely well for its intentions. Function Grapher is an excellent tool for someone who may not be able to afford a graphing calculator or just needs a quick and simple graph. It is also useful if a student wants to print out a graph to include in an assignment or a paper. Technical Remarks: The different functions available in Function Grapher are very well defined and clearly available for students to access. It is also very easy to navigate around the graph and zoom in on specific sections of the graph. I gave it four stars because I think it is a great site, but could use a few more advanced features.
