This tells me that the (55, 40) is the vertex of the parabola. From the table given, you can see the symmetry of the data and I know it is a quadratic from the information given. The sample response below reflects a strong knowledge and understanding of the subject matter.ġ. Sample Strong Response to the Open-Response Item describe the speed(s) the car must maintain if the driver desires a fuel efficiency of at least 25 miles per hour.īe sure to show your work and explain the reasoning you use in analyzing and solving this problem.use the equation to calculate how many miles a car with 16 gallons of gas can travel if the car maintains a speed of 61 miles per hour and.graph the function on a coordinate grid, including all appropriate labels, and explain the meaning of any zeros and extrema in the context of this situation.find the quadratic function f( x) f of x, where x is in miles per hour, that describes the fuel efficiency of the car.Use your knowledge of quadratic relationships to develop a response of approximately 150 – to 300 words, or 1 – to 2 pages, in which you analyze the relationship between fuel efficiency and speed for the car. The fuel efficiency of a certain car can be represented by a quadratic function where fuel efficiency is a quadratic function of the speed at which the car is driven according to the data shown in the table below. Use the information below to complete the assignment that follows. Do not use more than two Response Sheets for this assignment. Note: For this assignment on the actual test, you may type a response into the on-screen response box and/or handwrite and scan your response using a Response Sheet provided for you. Prepare an organized, developed analysis on a topic integrating knowledge from at least two of the following: number sense and operations relations, functions, and algebra geometry and measurement probability, statistics, calculus, and discrete mathematics. Any response sheet that is not scanned before testing ends will NOT be scored. Only response sheets that are scanned before you end your test or before time has expired will be scored. When your testing time expires, a pop-up message will appear on-screen indicating the conclusion of your test session. Remember to review your work and make any changes you think will improve your responses.Īny time spent responding to an assignment, including scanning the response sheet(s), is part of your testing time. Your responses should be your original work, written in your own words, and not copied or paraphrased from some other work.īe sure to write about the assigned topics. The final version of each response should conform to the conventions of edited American English. Your responses should be written for an audience of educators in this field. ![]() Your responses must be communicated clearly enough to permit valid judgment of the evaluation criteria by scorers. The open-response item assignments are intended to assess subject knowledge. RATIONALE: soundness of argument and degree of understanding of the subject area.SUPPORT: quality and relevance of supporting evidence.SUBJECT KNOWLEDGE: appropriateness and accuracy in the application of subject knowledge.PURPOSE: the extent to which the response achieves the purpose of the assignment.Your responses to the assignments will be evaluated based on the following criteria. ![]() ![]() In your response to each assignment, you are expected to demonstrate the depth of your understanding of the subject area by applying your knowledge rather than by merely reciting factual information. ![]() Instructions for scanning your response sheet(s) are available by clicking the "Scanning Help" button at the top of the screen.Īs a whole, your response to each assignment must demonstrate an understanding of the knowledge of the field. provided using both the on-screen response box (for typed text) and a response sheet (for calculations or drawings) that you will scan using the scanner provided at your workstation.written on a response sheet and scanned using the scanner provided at your workstation, or.However, your final response to each assignment must be either: You may use the erasable sheet(s) to make notes, write an outline, or otherwise prepare your responses. Think about how you will organize your responses. Read the assignments carefully before you begin your responses. You will be asked to prepare a written response of approximately 150–300 words, or 1–2 pages, for each assignment. This section of the test consists of two open-response item assignments.
