What is a Test Blueprint? A table with rows and columns that is a plan for the way in which the questions in a test will be distributed Rows show number of questions and marks for each topic/standard Columns show number of questions and marks for depth of thinking levels Other names for this -- test specification, specification matrix, test plan 8
Use a Blueprint To plan individual tests Blueprint (or table of specifications) includes: Content Thinking skills Specific learning targets Emphasis (weight) This information helps you write a test that is interpretable as you intend 9

What is a Multiple-Choice Item? A multiple-choice item consists of one or more introductory sentences followed by a list of two or more suggested responses. The student must choose the correct answer. 13
Align requirements for multiple choice item performance to learning objectives Content Performance Thinking skills Objective items, especially multiple choice, can tap higher-order thinking if carefully written Clear presentation to students of what is required for each task or item 14
Multiple Choice Items Which president of the United States was elected to four terms? a. Abraham Lincoln b. Theodore Roosevelt *c. Franklin D. Roosevelt stem alternatives key distractors 15
Guidelines for writing Multiple Choice Items Assess an important aspect of the unit’s instructional targets. Match your assessment plan in terms of performance, emphasis, and number of points. Ask a direct question or set a specific problem. Put the alternatives at the end. Put repeated words in the stem. 16
Guidelines for writing Multiple Choice Items Place the word in the stem and definitions in the alternatives, if testing definitions. Avoid “cluing” and “linking” (where the correct answer of one item depends on another item). Avoid textbook wording. Use simple vocabulary and sentence structure. 17
Guidelines for writing Multiple Choice Items Use consistent, correct punctuation and grammar relative to the stem. Avoid phrasing the item so the student’s personal opinion is an option. Arrange alternatives in a logical order. Have distractors that would be plausible to non- knowledgeable students. 18
Guidelines for writing Multiple Choice Items Have homogenous alternatives. Have distractors based on common errors or misconceptions if possible. Have 3 to 5 functional alternatives. Have one correct or best answer. Avoid “all of the above” and use “none of the above” sparingly. 19

A question for you What is wrong with the stem of the following multiple-choice question? “Which of the following states is the largest state in the United States?” a.Largest can be measured either geographically or by population. b. It measures opinion rather than fact. c. It measures only a lower order skill. d. It should be posed as a statement instead of a question. 27
A question for you Which of the following sets of alternatives would be best for a multiple-choice item about a battle in the Civil War? a. Davis, Grant, Lincoln, none of the above b. Lincoln, Mason-Dixon Line, Sherman, Vicksburg c. Grant, Jackson, Lee, Sherman d. Jefferson, Lincoln, Roosevelt, Washington 28
A question for you Which of the following sets of alternatives is best for the following multiple-choice item: "The perimeter of a rectangle 4 inches long and 2 inches wide is ______"? a. 6 inches, 8 inches, 12 inches b. 2 inches, 12 inches, 24 inches c. 11 inches, 12 inches, 13 inches 29
Circle the ball. 30
Context-dependent item sets Use introductory material Readings Tables, graphs, or charts Pictures Formulas, lists of terms or symbols Write a set of items requiring students to interpret the material 31
Why use Introductory Materials? Introductory materials (readings, graphs, tables, and maps) used in context-dependent item sets can help assess higher order thinking. Because they give students something to think about. 32
Context-dependent item sets A good way to assess higher-order thinking The introductory material allows you to present novel material to students The questions can then be about interpreting, not recalling, material 33

Frontier Women 36 Like the early colonial women settlers of the backwoods, frontier women made everything their families needed. Most began work at daybreak and did not rest until late evening. They cooked, spun cloth, made clothing, raised children, and tried to keep their dirt homes clean. They cleared and plowed fields, tended and harvested crops, milked the cows, raised hogs, rode and trained horses, and did just about every chore on the farm. The women not only worked, they also made most of their own tools. To make pitchforks, they attached handles to deer antlers. Many of the women learned to use a knife well enough to carve spoons, forks, and bowls out of animal bones. They fashioned cups and containers out of vegetable gourds and animal horns. Which statement best describes the frontier women? A.They lived dangerous lives and tamed the West. B.They hunted to provide food for their families. C.They frequently worried about the safety of their homes. D.They worked hard and possessed many skills.
What is a constructed-response item? Constructed response test items ask students to compose their responses, and are scored with a judgment of the quality of those responses. 37
Types of Constructed Response Items Restricted response essay items limit both the content of students’ answers and the form of their written responses. Extended response essay items require students to express their own ideas and to organize their own answers. Show-and-explain-the-work problems on math and science tests are also constructed response items. 38
Restricted Response Essays Limit the responses Still should require higher-order thinking, not recall Can include interpretive material Several restricted response essays usually yield better information about student understanding than one extended essay 39
Essay Items Write items that require students to explain a process, defend a position, etc. – something worth writing about, NOT just “coming up with” facts and concepts Write scoring scales or rubrics that match the learning objective(s) Usually best to score all answers to one question before scoring the next 40
Example A bird-watcher wants to see many birds in a one- hour period. She decides to investigate which type of food will attract more birds in her backyard. She has a choice of two types of bird food. 1. Sunflower seeds 2. Thistle seeds Describe a fair test the bird-watcher could conduct to help her decide which food will attract more birds. What information should the bird-watcher collect from her test to help decide which type of food attracts more birds? 41
Example The two statements below represent contrasting views regarding the rapid development of the Brazilian rain forest. For each view, explain one probable reason for the speaker's attitude, and give one possible argument the speaker might make to defend his or her point of view. I.Brazilian developer: "Our nation’s prosperity depends on developing the rich resources of the rain forest.“ II.European diplomat at an international conference on Earth’s environment: "There is certainly a need for an international agreement on the responsible development of the rain forest." 42
Show-and-explain-the-work Problems 43 An amusement park has games, rides, and shows. The total number of games, rides, and shows is 70. There are 34 rides. There are two times as many games as shows. How many games are there? ______________________ How many shows are there? ______________________ Use numbers, words, or drawings to show how you got your answer.
Guidelines for Writing Essay Items Assess an important aspect of the unit’s instructional objective(s). Match your assessment plan in terms of performance, emphasis, and number of points. Require students to apply their knowledge to a new or novel situation. 44
Define a task with specific directions (rather than leave the task so broad that virtually any response can satisfy it). Use a level of complexity appropriate for students’ level of maturity. Require the student to demonstrate more than recall of facts, definitions, generalizations or other ideas. Guidelines for Writing Essay Items 45
Word questions in a way that leads all students to interpret the item in the way you intended. Make clear to the students all of the following: (a) length of the required writing, (b) purpose for which they are writing, (c) amount of time to be devoted to answering this item, and (d) the basis on which their answers will be evaluated. Guidelines for Writing Essay Items 46
For essays requiring students to state and support their opinions on controversial matters, make clear to the students that their assessment will be based on the logic and evidence supporting their arguments, rather than the actual position taken or opinion stated. Guidelines for Writing Essay Items 47
A question for you Identify the flaw(s) in the following essay question: “List the major exports of Chile.” a.Requires only the recall of facts. b.Does not specify length or criteria for evaluation. c.Does not require students to support an opinion. d.Only (a) and (b): “requires only recall” and “does not specify criteria” 48
A question for you In a current events unit in a Social Studies class (where the learning goals are for students to understand current events in the news), students are asked to write an essay on the question, “Who do you think should be the next President of the United States?” Which of the following is the best critique of this essay question? a.It’s a bad question, because it calls for an opinion. b.It’s a bad question, because it asks about events that haven’t happened yet. c.It’s a good question, and should be given as an in-class essay after some directions about length and evaluation criteria have been added. d.It’s a good question for an out-of-class essay, and students should be asked to support their opinion with material from the news media and other sources. 49
A question for you What is the MOST important flaw in this essay question: “We have studied the organization of the federal government. Explain each step in the process for passing a bill into law.” a.Does not specify the content the essay is to be about. b.Does not require application or higher-order thinking. c.Does not provide criteria for evaluation. d.Does not give time limits. 50
A question for you A teacher gave her students this essay question: “Evaluate the effect of air pollution on the quality of life in the western part of this state.” One student wrote, “It’s horrible!” Which of the flaws in this question allowed for such a response? a.The question calls for an opinion. b.The question is too broad. c.No directions were given. 51
Example General scoring rubric for an essay question 53 210 Main Idea and Supporting Details An important main idea is clearly stated. Supporting details are relevant and convincing.
