In my Technology Education class, I encountered a significant challenge with students struggling to grasp the application of electrical circuits and the calculations involved in Ohm's Law. Many students exhibited difficulty in conceptualizing how electrical components, such as resistors, capacitors, and power sources, functioned together within a circuit. This lack of understanding stemmed from a combination of abstract theoretical concepts and the physical hands-on applications required to build and troubleshoot circuits. Despite numerous demonstrations and visual aids, many learners found it hard to link the conceptual knowledge of voltage, current, and resistance to practical scenarios, leading to confusion when attempting to apply Ohm's Law to real-life electrical problems.
Furthermore, the mathematical aspects of Ohm's Law presented an additional barrier for many students. Although they had foundational knowledge of arithmetic, the application of algebraic formulas to solve for unknown variables in a circuit context proved challenging. The mathematical manipulation involved in calculating values such as voltage (V = I * R), current (I = V / R), and resistance (R = V / I) was often met with resistance. This not only hindered their ability to complete assignments but also impacted their confidence in their problem-solving skills. The cumulative effect of these challenges resulted in a classroom atmosphere where students felt overwhelmed and frustrated, which often inhibited their willingness to engage with the material and participate actively in hands-on activities designed to reinforce their learning.
