The present study represents a small part of a much broader project involving the design of a new curriculum approach to teach the energy concept in its entirety. Subsequently, an original piece of educational software was designed and developed to teach the energy concept using this curriculum approach. To test both the new curriculum as well as the educational software, a dual testing technique was followed. The novel curriculum was implemented in class using conventional teaching techniques (103 students). Separately, the new educational software was also tested in a classroom environment (109 students), while all these were compared to a control group of ordinary school leavers (231 students). The data-taking and data-analysis preformed have been extensive. A small part of the final results of this dual educational trial are presented herein, in which some educational observations are also presented, and conclusions reached are briefly discussed.
