Indicator
Value Makes appropriate connections between activities and learning (!2 relevant tasks identified and related to Pre-/Post- ideas) 5 Make some appropriate connections between activities and learning (One relevant task identified and related to Pre-/Post- ideas) 4 Incomplete connection between activities and learning (Tasks identified without connection to ideas.) 3 Activities identified with little connection to learning (Mere mention of activity without specific reference to tasks within activity) 2 No activities identified 1 5. Writing mechanics: Indicator Value Clearly written, good connections, very few minor mechanical errors (0-1 minor errors of all types per page) 5 Clearly written, connections need improvement, some mechanical errors (1-2 minor errors of all types per page) 4 Vaguely written, disjointed, or many mechanical errors (3-4 minor errors of all types/page or 1-2 major grammatical/style errors/page) 3 Very vague, disjointed, multiple mechanical errors (5-7 errors of all types/page or fewer minor errors plus 2-3 major grammatical errors) 2 Writing very difficult to follow, usage non-conventional 1 6. Peer Review: Indicator Value Indication of serious effort to inform classmate of ways to improve Essay. 5 TOTAL SCORE (30 points possible) Teacher Education in Physics 67 5 Appendix 1.D—Performance Task You will be given four "mystery" boxes numbered 1 - 4. The contents of the boxes are not visible, but each box has two protruding wires, labeled A and B. The boxes contain various combinations of light bulbs connected to terminals A and B by conducting wires inside the box as pictured below: A B Single bulb A B Two bulbs in series A B Two bulbs in parallel A B Two bulbs in parallel connected in series to a third bulb You cannot see what is in the boxes—all you can see are the terminals, A and B, protruding from the box. You will also be given a “tester” which consists of a battery and a bulb and two test lead wires as shown to the right. (Although the battery and bulb are arranged slightly differently, this is the same as the “circuit tester” that you learned about in a previous Making Connections assignment.) YOUR TASK WILL BE TO USE THIS TESTER TO IDENTIFY THE CONTENTS OF THE FOUR BOXES. To make it easier to connect your tester to the boxes, the terminal wires A for all four boxes are connected together as shown to the right. You can connect one lead from the tester to this common “A” junction and leave it connected as you connect the second tester lead to the terminal B wire for each individual box. You will do this performance task in three steps: Step 1. BEFORE DOING ANY MEASUREMENTS, think about a plan to identify the contents of each of the mystery boxes without opening the boxes. Your plan should consider what you will be looking for when you connect the tester to the mystery boxes to enable you to decide which circuit pictured above is in which box. (Note: It will not be acceptable to explain how you find the contents of three boxes and then use the argument “by elimination” for identifying the fourth box. You must explain how the tester is used to identify the contents all four boxes.) Download 231.88 Kb. Do'stlaringiz bilan baham: |
