Non so se resterà "free" per molto, quindi dateci un'occhiata ora finché siete in tempo.Art of Problem Solving's NEW innovative online learning system!
Alcumus offers students a customized learning experience, adjusting to student performance to deliver appropriate problems and lessons. Alcumus is specifically designed to provide high-performing students with a challenging curriculum appropriate to their abilities.
Current features of Alcumus include:
• Over 1100 problems with solutions. Many of the problems are from major national math competitions such as MATHCOUNTS and the American Mathematics Competitions series of tests.
• Over 60 video lessons (totaling over 6 hours!). The primary video instructor is Art of Problem Solving founder Richard Rusczyk, a former USA Math Olympiad winner and author of five Art of Problem Solving textbooks.
• An intelligent learning system. As the student gets stronger, Alcumus automatically provides more challenging material, and conversely, if the student is having difficulty with a particular topic, Alcumus provides additional practice.
• Detailed progress reports. Students can track their performance in various subjects, and revisit problems and lessons at any time.
• Tools for teachers to monitor their students' progress and access Alcumus videos. For more information on how to sign up as a teacher, login to artofproblemsolving.com and then view the Alcumus instructions. (You will be directed to the Instructions page if you login from the login link contained in this paragraph.)
• Alcumus is currently free!
