8What 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 distributedRows show number of questions and marks for each topic/standardColumns show number of questions and marks for depth of thinking levelsOther names for this -- test specification, specification matrix, test plan
9Use a Blueprint To plan individual tests Blueprint (or table of specifications) includes:ContentThinking skillsSpecific learning targetsEmphasis (weight)This information helps you write a test that is interpretable as you intend

13What 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.
14Align requirements for multiple choice item performance to learning objectives ContentPerformanceThinking skillsObjective items, especially multiple choice, can tap higher-order thinking if carefully writtenClear presentation to students of what is required for each task or item
15Multiple Choice ItemsWhich president of the United States was elected to four terms? a. Abraham Lincoln b. Theodore Roosevelt *c. Franklin D. Rooseveltstemdistractorsalternativeskey
16Guidelines 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.
17Guidelines 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.
18Guidelines 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.
19Guidelines 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.
20Evaluate the Stems Why did housing prices drop so rapidly in 2008? Which one of the following statements is true about housing prices?Which one is better? Why?
21Evaluate the Stems An orangutan is a Orangutans are classified as Which one is better? Why?

24Evaluate the StemsWhich of the following illustrates what is meant by condensation?Which of the following does not illustrate what is meant by condensation?Which one is better? Why?Which one is better? Why?
25A question for youWhich of the following provides the best stem for a multiple-choice item? a. Penicillin is b. Penicillin was discovered by c. Penicillin, which has many uses in medicine, was discovered by d. Who discovered penicillin?
26A question for youWhich of the following provides the best stem for a multiple-choice item? a. Which of the following did not contribute to the great depression? b. One major factor that contributed to the great depression is c. The great depression was d. The great depression was caused by
27A question for youWhat is wrong with the stem of the following multiple-choice question? “Which of the following states is the largest state in the United States?”Largest can be measured either geographicallyor 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 aquestion.
28A question for youWhich 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
29A question for youWhich 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
31Context-dependent item sets Use introductory materialReadingsTables, graphs, or chartsPicturesFormulas, lists of terms or symbolsWrite a set of items requiring students to interpret the material
32Why 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.
33Context-dependent item sets A good way to assess higher-order thinkingThe introductory material allows you to present novel material to studentsThe questions can then be about interpreting, not recalling, material

35Cars Iron Aluminum Coal According to the map, which of the following does the United States both export to Canada and import from Canada?CarsIronAluminumCoal
36Frontier Women Which statement best describes the frontier women? 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?They lived dangerous lives and tamed the West.They hunted to provide food for their families.They frequently worried about the safety of their homes.They worked hard and possessed many skills.
37What 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.
38Types 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.
39Restricted Response Essays Limit the responsesStill should require higher-order thinking, not recallCan include interpretive materialSeveral restricted response essays usually yield better information about student understanding than one extended essay
40Essay ItemsWrite items that require students to explain a process, defend a position, etc. – something worth writing about, NOT just “coming up with” facts and conceptsWrite scoring scales or rubrics that match the learning objective(s)Usually best to score all answers to one question before scoring the next
41ExampleA 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.Sunflower seedsThistle seedsDescribe 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?
42ExampleThe 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.Brazilian developer: "Our nation’s prosperity depends on developing the rich resources of the rain forest.“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."
43Show-and-explain-the-work Problems 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.
44Guidelines 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.
45Guidelines for Writing Essay Items 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.
46Guidelines for Writing Essay Items 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.
47Guidelines for Writing Essay Items 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.
48A question for youIdentify the flaw(s) in the following essay question: “List the major exports of Chile.”Requires only the recall of facts.Does not specify length or criteria for evaluation.Does not require students to support an opinion.Only (a) and (b): “requires only recall” and “does not specify criteria”
49A question for youIn 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?It’s a bad question, because it calls for an opinion.It’s a bad question, because it asks about events that haven’t happened yet.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.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.
50A question for youWhat 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.”Does not specify the content the essay is to be about.Does not require application or higher-order thinking.Does not provide criteria for evaluation.Does not give time limits.
51A question for youA 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?The question calls for an opinion.The question is too broad.No directions were given.
53Example General scoring rubric for an essay question 2 1 Main Idea and Supporting DetailsAn important main idea is clearly stated. Supporting details are relevant and convincing.A main idea is stated. Supporting details are mostly relevant.A main idea is not stated, or is not correct. Supporting details are not relevant or are missing.ExplanationHow the evidence supports the main idea is clear, reasonable, and well explained.How the evidence supports the main idea is mostly clear and reasonable. Some explanation is given.How the evidence supports the main idea is not clear, not reasonable, and/or not explained.
