Holistic Question Scoring Guide

(5 marks)
Check before you submit your work:

Did you write your answer as a paragraph with proper sentences?
Did you clearly answer all parts of the question?
Did you state and explain any relevant physics principles as shown on your physics data sheet?

Did you state and explain any relevant equations?

Holistic Scoring Guide

Score	Description
5	The nature of a response that will receive a score of 5 has the following characteristics: The response addresses, with appropriate knowledge, all the major concepts in the question (all bullets must be attempted). The student applies major physics principles in the response (appropriate physics principles are stated). The relationships between ideas contained in the response are explicit* (physics principles are clearly linked to the application). The reader has no difficulty following the strategy or solution presented by the student. Statements made in the response are supported explicitly.* Note: the response may contain minor errors or have minor omissions.
4	The nature of a response that will receive a score of 4 has the following characteristics: The response addresses, with appropriate knowledge, all the major concepts in the question (all bullets must be attempted). The student applies major physics principles in the response (appropriate physics principles are stated). The relationships between the ideas contained in the response are implied(physics principles are stated but not properly linked to the application). The reader has some difficulty following the strategy or solution presented by the student. Statements made in the response are supported implicitly. Note: the response is mostly complete and mostly correct, although it may contain errors or have omissions, and contains some application of physics principles.
3	The nature of a response that will receive a score of 3 has the following characteristics: The response addresses, with some appropriate knowledge, all the major concepts in the question (all bullets must be attempted). The student does not apply major physics principles in the response (all appropriate physics principles are not stated). There are no relationships between the ideas contained in the response (physics principles are stated but not applied). The reader may have difficulty following the strategy or solution presented by the student.
2	The nature of a response that will receive a score of 2 has the following characteristic: The response addresses, with some appropriate knowledge, two of the major concepts in the question (only two bullets are attempted).
1	The nature of a response that will receive a score of 1 has the following characteristic: The response addresses, with some appropriate knowledge, one of the major concepts in the question (only one bullet is attempted).
0	The student provides a solution that is invalid for the question.

*Explicit means the response is clearly stated; the marker does not have to interpret.

**Implicit (implied) means the response is not clearly stated; the marker must interpret.

For example:

Explicit: An electron has a negative charge while a proton has a positive charge.

The answer is clear with no possible misinterpretation.

Implicit: An electron has a negative charge while a proton does not.

The answer is not clear because the marker does not know if a proton is neutral or positively charged. There is more than one possible way to interpret the answer.
