1 FOR TEACHERS ONLY PS P The University of the State of New York REGENTS HIGH SCHOOL EXAMINATION PHYSICAL SETTING/PHYSICS Thursday, June 3, 203 :5 to 4:5 p.m., only SCORING KEY AND RATING GUIDE Directions to the Teacher: Refer to the directions on page 2 before rating student papers. Updated information regarding the rating of this examination may be posted on the New York State Education Department s web site during the rating period. Check this web site at: and select the link Scoring Information for any recently posted information regarding this examination. This site should be checked before the rating process for this examination begins and several times throughout the Regents Examination period. Part A and Part B Allow credit for each correct response. Part A Part B

2 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 Scoring Regents Examinations in the Sciences, which may be found on the Department web site at Do not attempt to correct the student s work by making insertions or changes of any kind. If the student s responses for the multiple-choice questions are being hand scored prior to being scanned, the scorer must be careful not to make any marks on the answer sheet except to record the scores in the designated score boxes. Marks elsewhere on the answer sheet will interfere with the accuracy of the scanning. For Part A and Part B, indicate by means of a check mark 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. At least two science teachers must participate in the scoring of each student s responses to the Part B 2 and Part C open-ended questions. Each of these teachers should be responsible for scoring a selected number of the open-ended questions on each answer paper. No one teacher is to score more than approximately one-half of the open-ended questions on a student s answer paper. Teachers may not score their own students answer papers. 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, 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 scale score by using the conversion chart that will be posted on the Department s web site at: on Thursday, June 3, 203. The student s scale score should be entered in the labeled box on the student s answer booklet. The scale score is the student s final examination score. On the front of the student s answer booklet, raters must enter their initials on the lines next to Rater or Rater 2. Schools are not permitted to rescore any of the open-ended questions on this exam after each question has been rated once, regardless of the final exam score. Schools are required to ensure that the raw scores have been added correctly and that the resulting scale score has been determined accurately. Because scale scores corresponding to raw scores in the conversion chart may change from one administration 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 Teachers should become familiar with 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 This guide provides a set of directions, along with some examples, to assist teachers in rating parts B 2 and C of the Regents Examination in Physical Setting/Physics. 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 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 credit if the student has listed the values with units and written a correct equation. Allow credit for the correct answer (number and unit). If the number is given without the unit, allow credit if the credit for units was previously deducted for this calculation problem. Penalize a student only once per calculation problem for incorrect or omitted units. Allow credit if the answer is not expressed with the correct number of significant figures.
