Abstract Title: Singapore secondary one students’ preconceptions on speed
Abstract: We report on the research findings on Singapore secondary one (Grade 7) students' preconception of speed:  1) The idea of someone ahead being faster than the one behind is prevalent among students answering the open-ended question, 2) The idea becomes less prevalent when the question becomes more guided, streamlining students' thinking towards the distance apart between two moving objects, 3) While most students were able to choose the correct choice that states that two boys who are running have the same speed because they remain the same distance apart, their explanations do not invoke the concept of speed as distance moved per unit time, and 4) Many students were not aware that in the definition of the average speed of a journey, the resting time was included as part of the total time elapsed. The data were from two batches of students at a reputable school.
