Directios to the Teacher Follow the procedures below for scorig studet aswer papers for the Physical Settig/Physics examiatio. Additioal iformatio about scorig is provided i the publicatio Iformatio for Scorig Regets Examiatios i the Scieces. Use oly red ik or red pecil i ratig Regets papers. Do ot attempt to correct the studet s work by makig isertios or chages of ay kid. For Part A ad Part B 1, idicate by meas of a check mark each icorrect or omitted aswer. I the box provided at the ed of each part, record the umber of questios the studet aswered correctly for that part. At least two sciece teachers must participate i the scorig of each studet s resposes to the Part B ad Part C ope-eded questios. Each of these teachers should be resposible for scorig a selected umber of the ope-eded questios o each aswer paper. No oe teacher is to score more tha approximately oe-half of the ope-eded questios o a studet s aswer paper. Studets resposes must be scored strictly accordig to the Scorig Key ad Ratig Guide. For ope-eded questios, credit may be allowed for resposes other tha those give i the ratig guide if the respose is a scietifically accurate aswer to the questio ad demostrates adequate kowledge as idicated by the examples i the ratig guide. Fractioal credit is ot allowed. Oly whole-umber credit may be give to a respose. Uits eed ot be give whe the wordig of the questios allows such omissios. Raters should eter the scores eared for Part A, Part B 1, Part B, ad Part C o the appropriate lies i the box prited o the aswer booklet, ad the should add these four scores ad eter the total i the box labeled Total Writte Test Score. The, the studet s raw score o the writte test should be coverted to a scale score by usig the coversio chart that will be posted o the Departmet s web site at: http://www.p1.ysed.gov/apda/ o Wedesday, Jue 15, 011. The studet s scale score should be etered i the labeled box o the studet s aswer booklet. The scale score is the studet s fial examiatio score. O the frot of the studet s aswer booklet, raters must eter their iitials o the lies ext to Rater 1 or Rater. Begiig i Jue 011, schools are o loger permitted to rescore ay of the ope-eded questios o this exam after each questio has bee rated oce, regardless of the fial exam score. Schools must, however, esure that the scores have bee tabulated correctly ad that the resultig scale score has bee determied accurately. Because scale scores correspodig to raw scores i the coversio chart may chage from oe examiatio to aother, it is crucial that for each admiistratio, the coversio chart provided for that admiistratio be used to determie the studet s fial score.

Teachers should become familiar with the Departmet publicatio Regets Examiatio i Physical Settig/Physics: Ratig Guide for Parts B ad C. This publicatio ca be foud o the New York State Educatio Departmet web site http://www.p1.ysed.gov/apda/sciece/phyratg0.pdf. This guide provides a set of directios, alog with some examples, to assist teachers i ratig parts B ad C of the Regets Examiatio i Physical Settig/Physics. Scorig Criteria for Calculatios For each questio requirig the studet to show all calculatios, icludig the equatio ad substitutio with uits, apply the followig scorig criteria: Allow 1 credit for the equatio ad substitutio of values with uits.

Allow 1 credit for the correct aswer (umber ad uit). If the umber is give without the uit, allow credit if the credit for uits was previously deducted for this calculatio problem. Pealize a studet oly oce per calculatio problem for icorrect or omitted uits.
