10. What is a concept inventory?  measuring instrument to evaluate pupils’ working knowledge of a specific set of concepts (e.g. Newton’s axioms)  Typically organized as multiple-choice test (reproducible and easy to administer)  questions and response choices are the subject of extensive research  each question includes one correct answer and several distractors  distractors are incorrect answers based on students' commonly held misconceptions  Concept inventories are evaluated to ensure test reliability and validity 10 W.

11. Example of a concept test - FCI 11 Force Concept Inventory Item 24 The diagram shows a rocket coasting in space in the direction indicated by the arrows. Between N and P no external force acts on the rocket. When it reaches point P, the rocket fires its engines as shown to provide a constant acceleration until it reaches a point Q in space. Which path best represents the path of the rocket between P and Q? D Hestenes, M Wells and G Swackhamer (1992) Force concept inventory, The Physics Teacher, 30, pp. 141-158 http://science.uniserve.edu.au/disc/phys/aip/jmp.html

12. 12  No concept inventory on particle physics exists so far  Difficulty: where to set the focus? Which are important concepts in particle physics?  My suggestion: see concept map (thanks to Prof. Kobel, TU Dresden)  Example Question: What kind of track would a neutron leave inside a cloud chamber?
