This research is directed at Junior High School students in the eighth and ninth grades and it focuses on the investigation of their ability to adopt and implement system-thinking tools when called upon to understand and analyze a technological system.
The aim of the research is to investigate how Junior High School students understand and apply the concept of “the system and its characteristics”.
As part of the research, a concepts questionnaire was distributed to all the students before and after the study unit was taught. The findings from this research were analyzed both quantitavely and qualitatively. Analysis of the answers given by the students revealed that after completion of the study unit program, the most significant change to their thinking was their newfound readiness to use a graphic model to describe a system. The findings indicate that in order to inculcate the use of theoretical system-thinking tools and impart system-thinking skills to the students, it will be necessary to develop a teaching program that comprises a balanced integration of three factors: The engineering and scientific background that is required in order to understand the functioning of systems and mechanisms; the impartation of the skills required in order to use models and define all the various elements that comprise a system; practical work in an environment that uses modular system modeling techniques or real systems and extensive practical experience in the use of models to analyzes and design technological systems.
