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.

The Impact of Psychomotor Element in Cognitive Domain Achievement of Electronics 1 during Open Distance Learning (ODL)

“…The objective of the developed kit instrument is to support the hypothesis that if students repeatedly construct simple circuits during hands-on exercise, their practical intelligence improves in respect of experience and time, and they will be able to construct complicated electrical circuits in actual implementation due to the level of practical intelligence. The results show that there is a correlation between the two and further support the importance of the practical domain to help students' cognitive understanding (Daud et al, 2018).…”

A Comparison of Psychomotor Domain Assessment in Water Engineering Laboratory between F2F and ODL

“…The teaching and learning, and assessment for this course is based on psychomotor domain since it involves laboratory work. Psychomotor skill is very important to prepare students to practice engineering (Daud et al, 2018). Student's technical skills can be improved and nurtured through psychomotor domains.…”

Adapting Chaos Theory for Undergraduate Electrical Engineers

“…The classroom environment provides the perfect opportunity to assess cognitive and affective skills 15,16 , while laboratories are better suited to evaluate psychomotor skills [17][18][19][20] . Some researchers have developed custom assessment tools and kits that allow them to measure psychomotor 19,21 and affective 16 skills. Almost every faculty member knows how to assess cognitive skills.…”
