Formative assessment, which focuses on the use of learners' responses, is an important concept for instructional improvement. This paper presents a web-designed class support system called Key Words Meeting (KWM). KWM stores information on teacher's pre-class key words and their description as well as the student's post class responses to them with memorized key words and their descriptions. By comparing these, the teacher can obtain scales that represent how well each instructional content is transmitted and understood by the students. Teachers can also refer to KWM indicators to manage which key words need to be supplemented. The teacher provides feedbacks to the students by commenting based on their responses and estimated comprehensions. Our experimental results show that KWM helps teachers manage feedbacks and helps students review the class effectively throughout the semester.

In “the measurement and control by the computer program” taught in junior high school, the students are expected to master ‘the system of measurement and control’ which is consisted of actuators, sensors, interface and computer, and also to understand the fact that the information processed by the computer program determines the operation-objectives of the measurement and control system. It is expected to make each of these factors easy to understand, separate them physically, and to make them visible, so that the students might be able to understand each of these items. In this study, a newfound, easy to understand, physically separated and visualized interface has been developed by the authors. In addition, the software for the system of measurement and control has been developed based upon Logo-writer, and the authors have developed the software that will help students use the commands easily.
