Real-Life Applications of Ohm's Law: To help students connect with Ohm's Law and grasp its real-world relevance, I implemented a hands-on project where learners were tasked with building their own simple circuits at home. This approach aimed to bridge the gap between theoretical concepts and practical applications, fostering an engaging learning experience. Each student was required to gather materials — such as batteries, wires, bulbs, and resistors — to create a circuit of their choice while applying Ohm's Law (V = IR) to understand the relationship between voltage, current, and resistance. By physically constructing a circuit, students could visualize and manipulate the variables, paving the way for a deeper understanding of how these principles apply to everyday electronics and household electrical systems.
Instructional Support: Prior to the project, I provided students with comprehensive instruction on how to calculate voltage, current, and resistance using Ohm's Law. I created instructional videos and worksheets that included step-by-step guidance and examples to facilitate their learning. Additionally, I organized virtual Q&A sessions where students could reach out with questions or seek clarification on concepts they found challenging. This scaffolded approach ensured that students had the necessary support and resources to successfully complete their circuits, encouraging them to experiment and think critically about the components and their functions.
Evaluating Effectiveness: The success of this project was measured through both formative and summative assessments. For formative assessment, I encouraged students to maintain a project journal documenting their process, including sketches of their circuits, calculations using Ohm's Law, and reflections on their learning experience. This journal served as a tool for me to gauge their understanding and provide timely feedback. Additionally, during final presentations, students showcased their projects, demonstrating their circuits and explaining the application of Ohm's Law in their designs. This peer-sharing activity not only reinforced their learning but also allowed them to articulate concepts confidently.
Assessment Tools: To evaluate the outcomes of this initiative, I developed a rubric that assessed students based on the clarity and accuracy of their project journals, the functionality and creativity of their circuits, and their ability to explain the underlying principles of Ohm's Law during presentations. Each criterion had specific point values, allowing for a transparent grading process. The combination of reflective journaling, peer presentations, and rubric-based evaluation enabled me to measure both the students’ understanding and their ability to apply Ohm's Law in real-world contexts effectively. Overall, the response from students was overwhelmingly positive, and many expressed newfound interest and confidence in working with electrical concepts, indicating that the project successfully addressed the initial teaching and learning problem.
