This a guest post from Jeremy Leaf, a third year PhD student in the School of Physics and Astronomy at the University of Nottingham and a member of the ENTHUSE project team.
It is one of our first electronics sessions. An Ethiopian teacher is learning how to use a multimeter and breadboard. Having measured the resistance of a number of discrete resistors using a multimeter, I suggest he try to measure them in series using the breadboard. He chooses two resistors and, on paper, calculates what the total resistance should be. He then carefully measures across both resistors in series. The teacher’s face lights up as he breaks into a wide smile. The theory is correct.
The process of learning a physical theory, and then observing it manifest itself in an experiment, is a vital pathway to understanding physics. It allows us to grasp difficult concepts and truly understand their nature. Unfortunately, in Ethiopia, physics education stops at the textbook. The education system has neither the funds nor expertise to employ physical experiments in their schools. Our assignment was to show how experimental physics could be taught using locally available materials. We also employed some more advanced apparatus, such as multimeters and breadboards, in the hope that they would be able to acquire these in time.
Simple apparatus and experimental concepts that we take for granted are often totally new to many physics teachers in Ethiopia. This project was an exciting opportunity to make a small but meaningful impact on the futures of those who go to school here, as well as forge a link between our two countries. Education is key for this country to develop a generation of young Ethiopians that can think critically and creatively. I feel immensely privileged to have been a part of that process.
