Kinematics of “Traffic Light”: A Socio Scientific Issue Performed by Undergraduate Physics Students

This research proposes an approach, especially on the socio-scientific issue in relating to the kinematics of traffic light (TL). The research utilised the one-shot case study that, an experimental treatment - modelling of SSI of the kinematics of TL is administered and then a post test is conducted to measure the effects of the treatment. Through the course of Physics for School, twenty-five junior physics students (3 males and 22 females) participated in the study. The results showed three main themes of the SSI item developed by students including: what should the driver do in the road for safety regarding the TL?; how much do the constant velocity for certain light of TL?; and which one the car across the TL?. Students' understanding of SSI issues on the kinematics of TL ranging from 48 to 92 point of 24 items. All items categorised as reasoning items and belong to HOTS; these questions are also contextual. It teaches us an orderly culture of traffic and road safety. Moreover, it also gives a lesson about science for all and science communication.
