Recently, Active Learning (AL) has been focused as the educational method. AL is different from traditional method of the class which is teacher-centric class, namely only teacher speak and students have the class passively [Ministry of Education, Culture, Sports, Science and Technology, 2012] [(foreign characters omitted) (NUCB Undergraduate School.), 2014]. AL is the style which students become active and they progress the class themselves actively. However, it is difficult to assess the students which have the AL, and it becomes hard about progressing the evolution of this style. The method of assess this two perspectives. One is that teachers have been able to have the class well? The other one is that students quorily (knowledge and skill) has been able to progress well? Generally, assessment of class is questioner-centric after closing the class at the end of semester. So we cannot feedback to our students that questionnaire's opinions. Moreover, generally the questionnaire to the students has included the issue that it is difficult to assess we want because subjectivity has strengthen. So we have advanced the investigation which can measure the degree of concentration against the class students have, using biological information as the assessment method we can measure it objectively. Using these results, we assess the degree of concentration against class of students while they are having the class of AL. This method makes us the situation which we can realize the visualization of the degree of actively while we realize the monitoring the situation of students in which they are having the class of AL. We use GSR, blinking, motion of the head as assessment indexes. We have selected the biological information we measure mentioned above and equipment we will use in order to reduce the strain of students by wearing the equipment, although we can select and use a variety of biological information and equipment to measure the situation of students. We can progress the class while visualizing the degree of concentration of students by using our system. As a result, we can reduce the class of AL which is imitative that is being a mere refraction of AL technique. Furthermore, we can apply our result to traditional teaching method because we can inform the situation which the students are becoming activated while the teachers are using a variety of skills which they drive the class well.
