Abstract

Background and Objective: The objective of the current investigation is to design a skill training activity in applied chemistry employing a science, technology, engineering, and mathematics (STEM) approach for undergraduate students majoring in chemistry, concentrating specifically on electroplating, with the intent to enhance scientific literacy, foster awareness, and cultivate a practical attitude towards chemical industrial activities. Materials and Methods: This investigation is characterized as applied in nature, regarding its objectives, the process of data collection employed to fulfill the aims, research inquiries, and essential information is predominantly bibliographic. Based on the collected information, educational content was developed to teach the topic of electroplating. Findings: Initially, the various applications, coating methodologies, and the historical development of the electroplating sector were explicated. Subsequently, the foundational principles of electroplating were systematically examined under the titles of copper and nickel-plating, sequentially. The concluding segment of the instructional material was devoted to the design of an electroplating system by the learner. This section was designed in such a way that the learner could create and test the electroplating system based on the theoretical and practical foundations presented in the first two sections of the content. At this stage, the learner reaches the skill of hands-on practice. Conclusion: Combining the topic of electroplating with a STEM approach can create motivation and interest in chemistry students and make them more scientifically and practically prepared to enter a teaching or industrial job.
