In usual problem exercises, students are provided information sufficient problems that include necessary and sufficient information to solve them. Under this condition, the students try to find method that can use all information in the problems. They, therefore, sometimes can solve the problem even they do not know the reason why the solution methods can be applied to the problems. Information insufficient problems are problems that do not include sufficient information. Therefore, students have to find the lacking information and complement it. In the problems in physics, we defined information insufficient problems by corresponding lacking information corresponds to values of physical attributes and complement activity to measuring of the attributes. We designed and developed a learning environment for problem exercise of information insufficient problem in physics. We also report the preliminary evaluation of the learning environment and the exercises.
