    A simple wave driver
    (IOP Publishing Ltd, 2015) Temiz, Burak Ka?an; Yavuz, Ahmet
    This study was done to develop a simple and inexpensive wave driver that can be used in experiments on string waves. The wave driver was made using a battery-operated toy car, and the apparatus can be used to produce string waves at a fixed frequency. The working principle of the apparatus is as follows: shortly after the car is turned on, the wheel starts to turn at a constant angular speed. A rod that is fixed on the wheel turns at the same constant angular speed, too. A tight string that the wave will be created on is placed at a distance where the rod can touch the string. During each rotation of the wheel, the rod vibrates the string up and down. The vibration frequency of this rod equals the wheel's rotation frequency, and this frequency value can be measured easily with a small magnet and a bicycle speedometer. In this way, the frequency of the waves formed in the rope can also be measured. © 2015 IOP Publishing Ltd.

    Do Students Trust in Mathematics or Intuition during Physics Problem Solving? An Epistemic Game Perspective
    (EURASIA, 2015) Yavuz, Ahmet
    This study aims to investigate (1) students' trust in mathematics calculation versus intuition in a physics problem solving and (2) whether this trust is related to achievement in physics in the context of epistemic game theoretical framework. To achieve this research objective, paper-pencil and interview sessions were conducted. A paper-pencil test was administered to 83 freshmen students. In paper-pencil test students were asked to calculate accelerations of four vehicles with different masses doing a drag race and to indicate which vehicle would win the race. Analyses revealed two themes: (1) "Math does not lie!" (for 43% of students) and (2) "Intuition does not mislead!" (for 57% of students). Interview analysis revealed that students' trust in mathematics calculation stems from the convincing and realistic nature of calculations and the misleading nature of intuitive knowledge. It was found that students' trust in intuitive knowledge stems from their intuitive expectations. The findings also revealed a significant association between students` trust in mathematics calculation and their achievement in the general physics course.
