Item # 5 (Short Answer)
The period of a swing (pendulum) is the amount
of time it takes for the person swinging to swing out and back.
Use the result of Experiments 1 and 2 to explain how the length
of the swing affects the period of the swing.
Content Definition:
The student should demonstrate an understanding
of how the length of a swing (pendulum) relates to the period
of its notion. The student should use the data presented in the
tables to explain that, the longer the swing is, the longer its
period will be.
Scoring Parameters:
Responses should have the following features:
|
NS
|
Not scorable; blank or insufficient response;
may be off-topic. |
|
1
|
A response at this level demonstrates little or
no understanding of how the length of a pendulum affects its
period. The response is incorrect and/or implausible. |
|
2
|
A response at this level demonstrates some understanding
of how the length of a pendulum affects its period. The student
gives a partially correct explanation. The response may be correct
but inadequately developed. The student may refer to the results
of the experiments, but in a flawed manner. The response reveals
incomplete understanding. |
|
3
|
A response at this level demonstrates an adequate
understanding of how the length of a pendulum affects its period.
The student's explanation is accurate, correctly used the results
of the experiments, and includes most of the essential details.
The response may be very general and contain some minor errors,
but the development of ideas is sufficient to demonstrated understanding. |
|
4
|
A response at this level demonstrates an advanced
understanding of how the length of a pendulum affects its period.
The response and the supporting information are accurate and
detailed. The student correctly uses the results of the experiments
to justify his/her response. The response is essentially free
of errors or flaws. The student exhibits a thorough and sophisticated
understanding of the concept. |
