Dichotomous distribution of scores. All answer spaces for Constructed Response (2 and 4 point items) Items have grids Highest score points are reserved for perfect papers (2.69) Constructed Responses items are embedded in test parts and are not identified as 2 or 4 point items Paper #3- ADP Release Item, ER- 4 points max Items Developed to Illustrate Scoring Notes The length of a rectangle is 8 inches longer than the width of the rectangle. The area of the rectangle is 33 square inches. Find the dimensions of the rectangle. Value points- how many? Items Developed to Illustrate Scoring Notes Graph y=x²-2x-8. (N1.a.) 1. Could be asked to find vertex 2. Could be asked to graph using x- intercepts and vertex 3. Shape will account for a value point (graph 5-points) 4. Watch concavity 5. Graph should be a function Items Developed to Illustrate Scoring Notes Graph the solution set of y≤2x+5. (L2.c.) Shading method should fully indicate a half plane Proper type of border line (shape and pattern) Items Developed to Illustrate Scoring Notes Solve 4x²=49 (N2.b.) Also see ADP sample #1 Show a solution strategy that accounts for all solutions, not just principal square root- this will account for a value point and in effect, a score point Solve |x-5|=26 (L2.b.) Items Developed to Illustrate Scoring Notes Simplify √(50x²y³) (O2.d.) Must account for absolute value (if necessary) for full score point value See Remaining ADP Release/Sample Items Questions? 609-984-9637 [email protected]
