I have made numerous presentations on the free technology tools for teachers in the past MECA conferences and have always received very positive comments from the audience. Because of the great success I had in the past, I gave another presentation this year which was somewhat similar with what I presented in previous years. However, my presentation this year focuses on 10 selective essential online tools that I believe are powerful as well as valuable to teachers and students. Below is the presentation I recently delivered at the 2011 MECA Conference on February 8, 2001 in Jackson, Mississippi. Please feel free to make comments or recommend your free online tools. Thanks.
