The Tennessee Board of Regents sponsors a project in "Mobilization & Emerging Technology" including the "Mobile Apps Resource Bank." Tens of thousands of mobile apps are categorized by educational function. Know a great app that isn't in the resource bank? You can add it for consideration/peer review!
This Website helps to learn and practice basic math functions including algebra, problem resolution skills, as well as methods of teaching students who feel frustrated with math. I think that this site provides enough information to learn and develop the skills of students in mathematics. Students can learn through private lessons individual or through a collective use of videos and with a forum for discussion with the experts.
In the earlier 20th century, educators had very few tools to use to accomplish their goal of educating students. Pens, pencils, markers, blackboards, notebooks, and construction paper were staples in every classroom. Eventually, technology evolved and better teaching tools emerged: overhead projectors, record players, filmstrips, movies, VCRs, tape recorders, Xerox printers, and four-function calculators.
