Appendix D

Table D1. General Approach

Nothing written. Physics approach is inappropriate. Successful solution is not possible. Physics approach is appropriate, but the manner of its application indicates a fundamental misunderstanding. Physics approach is appropriate, but a wrong assertion is made as a serious misinterpretation of given information. Physics approach is appropriate, but neglects one or more other principles necessary for the solution. Physics approach is appropriate and all necessary principles included, but errors are evident. Physics approach is appropriate and all necessary principles included without any conceptual errors.

Table D2. Specific Application of Physics 

Nothing written. Difficult to assess- Physics approach is appropriate, but the manner of its application indicates a fundamental misunderstanding. Solution does not proceed past basic statement of concepts. Vector/scalar confusion, or specific equations are incomplete, or confusion resolving vectors into components. Wrong variable substitution: Poor variable definition. Wrong variable substitution: Difficulty in translating to a mathematical representation. Careless use of coordinate system without a coordinate system defined. Careless use of coordinate system with a coordinate system defined. Careless substitution of given information. Specific equations do not exhibit clear inconsistencies with the general approach, but hard to tell due to poor communication. Specific equations do not exhibit clear inconsistencies with the general approach and the solution is clear.

 

Table D3. Logical Progression

Nothing written. Not applicable-one step problem. The use of equations appears haphazard and the solution unsuccessful. Student may not know how to combine equations. Solution is somewhat logical, but frequent unnecessary steps are made. Student may abandon earlier physics claims to reach answer. Solution is logical, but unfinished. Student may stop to avoid abandoning earlier physics claims. Solution meanders successfully toward answer. Solution progresses from goal to answer. Solution progresses from general principles to answer.

 

Table D4. Appropriate Mathematics

Nothing written. Solution terminates for no apparent reason. When an obstacle happens, “math magic” or other unjustified relationships occurs. When an obstacle happens, solution stops. Solution violates rules of algebra, arithmetic, or calculus. Serious math errors. Mathematics is correct, but numbers substituted at each step. Mathematics is correct, but numbers substitute at last step.
