The Modules Development of Material Testing by Using Constructivist Approach at Mechanical Engineering Department of UNIMED

This research aims to develop the material
testing modules by using constructivist approach at mechanical
engineering department of State University of Medan (Unimed).
The methode used was Research and Development Approaching
Methode (R & D) by Borg and Gall. The model development
phases for the studies referred to the development model of
Dick and Carey, consisting of need analyse phase, development
phase and evaluation phase. Data collection technique was
performed through observations, questionnaires and objectivity
tests. The result of reaserch and development was modules of
material testing by using constructivist approach. The modules
validity was determined by having some experts’ validations, one
to one evaluations and small group evaluations. The results of
reaserch showed that the expert validity giving an average
rating of 89,08 %, one to one evaluation was 87,03% average
and small group evaluation was 89,09% average, this showed
that the reaserch was valid to be used. The effectiveness of study
was obtained from pretest and post test which was conducted at
field trial, and proved the increasing of study results i;e 86,22%
The research and development delivered good implications to the
improvement of students’ instructional outcomes who were
taking material testing at mechanical engineering department of
Unimed.
