This paper describes a practical subject named "Mechanical design and practice IB" for a freshman. The subject has been given in 2009 for freshmen of our department of mechanical engineering, Ichinoseki National College of Technology. This practice is aiming at teaching basic techniques of mechanical engineering (e.g. measuring, calculating and practical use of tools). The program consists of (a) measuring techniques by venire caliper and micrometer, and use of pocket calculator, (b) how to use tools through dismantlement and assembly of a machine, (c) design and make a paper airplane. These practices are focusing on the development of a basic knowledge of mechanical engineering and a technique for solving problems, through "try and error". In this paper, the questionnaire results of this subject were also shown. The students attended this subject get the wide interest to the fundamental technology of the mechanical engineering.
