Adaptation to student's level

The program perceives the degree of proficiency of the students and consequently the difficulty of the presented problems is determined based on their success in solving the previous ones.
For example, in the Unit "Algebraic Expressions 1", in the Subject "Operations on Expressions", the students master the technique of simplifying expressions. The first problem is easy, say, simplify the expression 7y+8y. If the student fails to solve this one, the next problem will be very similar, say, 3x+9x. However, if the student succeeds, the next problem will be a little bit more difficult, say 4y-8y. Succeeding in solving this one will yield another problem, a little bit more difficult, say, 3-4x+8x-7 etc.

Another adaptive mechanism controls the proceeding from one level to the next one. There are two parameters that control this process:

• The student needs to solve a minimal number of problems
• The student needs to achieve a minimal grade.

A remedial student, who makes mistakes during the solving process, may need to solve more problems than the advanced student need. The final goal is that each student, remedial or advanced, will master the required degree of proficiency, before moving to more advanced topics.

MATH-TEACHER provides an additional degree of adaptation by enabling teachers to change these parameters.

Furthermore, MATH-TEACHER applies a special adaptive scheme for advanced students who achieve remarkable grades (above 90) by decreasing the number of the required solved problems as a condition to progress to the next level.

Students can view their grades and the rules for passing to the next level.
