Effective ways to test changes of practical intelligence in order to assess unintentional learning in laboratory classes

Abstract

Previous research shows that experience or academically called ‘practical intelligence’ in the field of engineering can be measured through comparing experience to the experts in the field. The expert teaches and shows the students the ways to complete some practical tasks based on their own practical intelligence, which they developed for years and becomes their behaviors. Thus after some or repeated hands-on exercises, the level of students’ practical intelligence continuously developed and close to the experiences possesses by the experts. By this way, the level of practical intelligence can be assessed if it is referring to the experts score. A measuring instrument, an ‘Automated Engineers Testing Kits’ consisted of a partially completed circuit in which a battery provides power for a flash light. This is a semi-completed circuit which requires students to diagnose why the light does not work and complete the necessary connections. The authors hypothesize that practical intelligence measured in the context of constructing simple circuits used for laboratory experiments will be correlated with performance in real constructing tasks on similar complicated electrical circuits. The results show the correlations between the level of practical intelligence and the ability to construct the circuits. The methodology is described in the paper.
