Abstract
Most electrical engineering students must make an extra effort to understand non-electrical engineering concepts in their study. An analogy approach is commonly selected by lecturer to assist the students to understand the concepts. In this paper, an analogy by conducting practical work is proposed. The objective of this practical class is to enhance the students understanding of the work principle of the economizer and what advantages will be gotten by adding economizer in the boiler. This study has been started to be implemented in 2nd semester academic year 2022/2023. The research result shows that the students who conducted the proposal practical class in 2nd semester academic year 2022/2023 demonstrated 38.75% much higher in understanding compared to the students who took the same subject in previous academic year 2021/2022 (93.75% vs 55.00% in correctly identifying economizer). All these students showed exemplary level capability for given rubric assessments, except in system efficiency improvement assessment which half of students have capability at satisfactory level. Also, more than ninety percent of students could identify the economizer, one of important components in a boiler, correctly. Whereas only fifty five percent of students who could do the same in previous academic year.
