We have developed a computer-based environment for learning by problem-posing as sentence-integration. The system was evaluated through two months usage in classroom by the ninety-nine students belonging to three classes of an elementary school second grade. Two systems were set up in each class and the students were allowed to use them freely. We used usage logs, questionnaires, information extraneous problem test, and schema priming test to evaluate children's problem solving performances. As the results, we found that (1) our system improved the problem solving ability of low performance students, (2) the second grade students of elementary school had posed problems continuously with the system, and (3) both students and teachers answered questionnaires that the problem-posing activity using this system is useful for learning.
