In this paper, we describe an Interactive Learning Environment which realizes the learning by Solution-Based Problem Posing for multi-digit subtraction. It is effective to master solution method that a learner poses problems which can be solved by the solution method. We call the type of problem posing Solution-Based Problem Posing. We have already developed some ILEs for arithmetical word problems. In the case of multi-digit subtraction, it is too difficult for learners to pose problems which can be solved by given solution method directly. Therefore, we suggest a method that learners solve and consider a problem and pose problem which can be solved by the used solution. In this paper, we describe (1) an interface for solving and considering a problem, (2) an interface for posing problems which can be solved by the used solution while referring the solution, (3) a function for diagnosis of the posed problem and for feedback, and also report an experimental evaluation in an elementary school.
