Appendix A: An example of the test item on the two-tier test contained in the ECT

A basketball player aims the ball at the basket and gets it through the ring. Based on the figure, which of the following can be said about the potential energy and the total mechanical energy of the ball as it moves from the point it has been thrown toward the basket? (Air friction is not to be considered)                    Potential energy Mechanical Energy A) First diminished, then increased Didn't change B) First increased, then diminished  Didn't change C) Didn't change Didn't change D) First diminished, then increased Diminished E) First increased, then diminished Increased Please explain the reason for your answer. ………………………………………………………………………………………………………… ………………………………………………………………………………………………………… …………………………………………………………………………………………………………     Appendix B: “Case Story Worksheet” Sample BEFORE THE EXAM The physics teacher who stood on ground floor took the bag which stood on the ground and walked to the elevator. The class which he was going to make an exam was on the third floor. He got on the elevator and arrived at the third floor. The teacher came into the class with his bag. Students were watching the bag because the exam questions were in it. The teacher went next to the table with his bag without moving his arm and put the bag on the table by lifting it. Then he greeted his students and “ desks are too close to each  other could you please come to the front’’ he said, by showing the students front rows. Elif and Fatma pushed their desks to the front, came closer immediately, when the other students on the front were coming closer to the front, the students who sat behind “ teacher , we are pushing our desks but we are not able to move on’’ they said. The teacher replied ‘’ you don’t have to come to the front.’’  The teacher started the exam after a part of students left their bags and books on the floor which stood on their desks, and wished good luck. In which of the cases mentioned above is there expenditure of energy? ………………………………………………………………………………………………………… ………………………………………………………………………………………………………… In which of the cases mentioned above work has been done in the physical meaning?
