Experimentation and Laboratory-Oriented Studies
The engineering programs at our university are designed to achieve student learning outcomes in maritime engineering knowledge and hands-on experience imposed by the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers. After completing the topic of electronics, students are expected to (1) understand the characteristics of basic electronic circuit elements, (2) configure and operate principles of electronic equipment, and (3) interpret electrical and simple electronic diagrams.
Recently, an automatic compartment temperature control project was designed and added in the Electronics Laboratory course to evaluate student learning outcomes in electronics. Different from previous isolated lab experiments, the new project requires students to integrate multiple experiments to design and build complex integrated circuits to solve a practical problem. Students first designed multiple electronic circuit modules to separately implement temperature measurement, temperature comparison and actuator control and then integrated all electronic circuit modules as complete electronic diagrams. Second, they used electronic circuit elements in lab to build integrated circuits on breadboards according to the complete electronic diagrams. Further, they tested the integrated circuits on breadboards to observe whether the integrated circuits can activate or deactivate an actuator in response to temperature change. They could use electronic equipment, such as multimeter, oscilloscope, etc, to diagnose the integrated circuits if necessary. After the completion of the project, all students’ integrated circuits were assessed by the instructor on whether they can measure indoor temperature, compare it with the desired temperature and invoke actuator control to automatically maintain indoor temperature. Additionally, an optional student questionnaire survey was conducted among the students who were participating in the project to assess student learning outcomes. The assessment results show a strong positive effectiveness of the project on understanding, configuration, operation and interpretation of electronics. Student narratives also imply the project led to interest and fun of electronics to them.
