PHYSICAL SETTING/PHYSICS – continued
Directions to the Teacher
Follow the procedures below for scoring student answer papers for the Physical
Setting/Physics examination. Additional information about scoring is provided in the publication
Information for Administering and Scoring Regents Examinations in the Sciences.
Use only red ink or red pencil in rating Regents papers. Do not attempt to correct the
student’s work by making insertions or changes of any kind.
On the detachable answer sheet for Part A and Part B–1, indicate by means of a checkmark
each incorrect or omitted answer. In the box provided at the end of each part, record the number
of questions the student answered correctly for that part.
Students’ responses must be scored strictly according to the Scoring Key and Rating Guide.
For open-ended questions, credit may be allowed for responses other than those given in the
rating guide if the response is a scientifically accurate answer to the question and demonstrates
adequate knowledge as indicated by the examples in the rating guide.
Fractional credit is not allowed. Only whole-number credit may be given to a response. Units
need not be given when the wording of the questions allows such omissions.
Raters should enter the scores earned for Part A, Part B–1, Part B–2, and Part C on the
appropriate lines in the box printed on the answer booklet, and then should add these four scores
and enter the total in the box labeled “Total Written Test Score.” Then, the student’s raw score on
the written test should be converted to a scaled score by using the conversion chart that will be
posted on the Department’s web site:
http://www.emsc.nysed.gov/osa/ on Wednesday, June 22,
2005. The student’s scaled score should be entered in the labeled box on the student’s answer
booklet. The scaled score is the student’s final examination score.
All student answer papers that receive a scaled score of 60 through 64 must be scored a
second time. For the second scoring, a different committee of teachers may score the student’s
paper or the original committee may score the paper, except that no teacher may score the same
open-ended questions that he/she scored in the first rating of the paper. The school principal is
responsible for assuring that the student’s final examination score is based on a fair, accurate, and
reliable scoring of the student’s answer paper.
Because scaled scores corresponding to raw scores in the conversion chart may change from
one examination to another, it is crucial that for each administration, the conversion chart provided
for that administration be used to determine the student’s final score.
[3]
PHYSICAL SETTING/PHYSICS – continued
Please refer to the Department publication Regents Examination in Physical Setting/Physics:
Rating Guide for Parts B–2 and C. This publication can be found on the New York State
Education Department web site
http://www.emsc.nysed.gov/osa/scire/scirearch/phyratg02.pdf.
Teachers should become familiar with this guide before rating students’ papers.
Scoring Criteria for Calculations
For each question requiring the student to show all calculations, including the equation and
substitution with units, apply the following scoring criteria:
• Allow 1 credit for the equation and substitution of values with units. If the equation
and/or substitution with units is not shown, do not allow this credit.
• Allow 1 credit for the correct answer (number and unit). If the number is given without
the unit, do not allow this credit.
• Penalize a student only once per equation for omitting units.
• Allow full credit even if the answer is not expressed with the correct number of significant
figures.
Part B–2
48 Allow 1 credit for marking an appropriate scale on the axis labeled “Potential Drop (V).”
49 Allow 1 credit for plotting all points accurately (±0.3 grid space).
50 Allow 1 credit for drawing the line of best fit. Allow credit for an answer that is consistent
with the student’s response to questions 48 and/or 49.
