Many variations exist, but items fall along a continuum from very simple responses to very extended responses. General reception by many educators is more positive to this item grouping than the selected response grouping. You will hear other professionals in education use different terms, usually in the context of saying “we need to replace our school’s multiple choice tests with essay exams.” (speaker is “old-school”, we now think of essay as one type among many types of constructed response items) performance assessment.” (speaker usually means he/she advocates something other than filling in bubbles on test sheet) authentic assessment.” (speaker wants the assessment task to be closer to a task we would do in everyday experience) alternative assessment.” (speaker wants an alternative to multiple choice exams, but this term is ambiguous as it also has other meaning; such as making individual student accommodations) 3 Key Challenges for Constructed Response Items Scoring Reliability The essence of a constructed response item is that it allows for variation in response; thus evaluation will require human judgment. Different scorers may have different judgments; one scorer may not be consistent over time or among students in class. Adequacy of Content Coverage Constructed response items tend to focus on central aspects of the content. If your testing target is a large body of knowledge or a large number of learning objective the constructed response approach may come up short. Constructed response items also take longer for students to answer so this also cuts coverage. Consequences for Student Misunderstanding The price a student pays when a constructed response item is misread is often more severe than when a selected response item is misunderstood. Consider a 50-item multiple-choice exam versus a 5-item essay exam. A student who misunderstands one essay item has 20% of their final score affected; misunderstanding a multiple choice is less harsh. 4 Constructed Response Items . . . Examples ahead There are a wide variety of constructed response items. For the purposes of this class we will restrict our discussion to creating and scoring the following items. As you come across other constructed response items, many of the suggestions and principles discussed here will apply to them. 5 Short Answer The short-answer item uses the constructed-response format. It requires the student to supply rather than select the correct answer. The typical task relates to simple facts or skills. The item can either be a direct question or an incomplete statement. Both versions can be answered by a word, phrase, number, or symbol. NOTE: Professionals use the term “incomplete statement” rather than “fill-inthe-blank.” Why? 6 Short Answer Questions . . . Presented via the classic chicken joke. What do you get when a chicken lays an egg on top of a barn? An eggroll Is chicken soup good for your health? Not if you're the chicken Which day of the week do chickens hate most? Fry-day Why does a chicken coop have two doors? With four doors it would be a sedan. Why did the chicken cross the basketball court? He heard the referee calling fowls How do two chickens dance when they dance together? Chick to chick Which ballroom dance will a chicken NOT do? The foxtrot How do you stop a rooster from crowing on Sunday? Eat him on Saturday 7 Short Answer Becomes Completion Using principles of good item writing, change each of the following short answer questions to completion items. Consider good item construction techniques when answering these questions: Where should the “blank” be located in the sentence? How long should it be? Should I use multiple blanks for phrases? Which day of the week do chickens hate most? How do two chickens dance when they dance together? Which ballroom dance will a chicken NOT do? How do you stop a rooster from crowing on Sunday? Scoring judgments . . . How close does the student’s response need to be to your envisioned answer to receive credit? What about spelling? 8 Some Final Thoughts on . . . Completion Items Completion items are similar to multiple choice questions without the distracters. Students need to recall the information being asked based on context clues found in the stem. Reasons for using them include: Completion items support learning objectives which focus on having students being able to summon up specific information from memory; however, don’t take stems verbatim from textbooks, lectures, overheads, etc. Why? Completion items can be constructed more quickly than multiple-choice items, since you don't need to create distracters. Sometimes it is difficult to construct a multiple-choice item without making the answer obvious. As there is no answer in a completion item, this type of item avoids this kind of problem. Completion items can help students gain proficiency in the use of the new context clues found in the item stem since, if students seek any memory associations to help their response, the help will be found in the stem. One difficulty in creating a completion item is to formulate the stem with sufficient contextual clues so that the wanted word is clearly indicated and ambiguity is avoided. 9 Let’s Look at . . . Using and Assessing Essays 10 Some overall thoughts on . . . Using Essay Items The structure of the essay item often means that successful essay responses may be measuring writing skill as well as measuring of content knowledge. Teach these skills before the test, not just on tests. Regular in-class essay writing should make the essay test approach less threatening and the test results more meaningful. EXAMPLE FOR STUDENTS: These simple steps will guide you through the essay writing process: Decide on your topic. Prepare an outline or diagram of your ideas. Write your thesis statement. Write the body. Write the main points. Write the subpoints. Elaborate on the subpoints. Write the introduction. Write the conclusion. Add the finishing touches. 11 Some overall thoughts on . . . Using Essay Items Essay items are best for measuring students' higher level cognitive abilities (e.g., Use freedom of response and originality are important - measures ability to organize, integrate, relate, and evaluate ideas); if you are thinking of measuring knowledge only, considering using something besides an essay. The essay prompt (called many names – question, stimulus) must be clearly stated for the students so they can write to it and so you can evaluate it effectively later. Consider this example: Poor item - "Why did we enter World War II?” Better "State three reasons cited by historians that you feel best explain America's entry into World War II.“ Provide a suggested length in terms of paragraphs or pages. Avoid optional questions (e.g., choose 3 of the following 5). While this is good for student morale, it makes it problematic to score. All essays are not likely to be of equal difficulty; if students know there will be a choice, they can focus study away from your learning objectives. 12 Thoughts to consider as you . . . Create Individual Essay Items As you create a high quality, valid essay item experience for your students, ask yourself these questions about every item and the scoring plan: 1. Does the item target a specified learning objective? 2. Is the level of reading skills required by this item below that of student ability? 3. Can all students answer the item in less than the allotted time? 4. Are higher level thinking verbs like "predict" or "compare and contrast" used rather than recall verbs like "list" and "name" or ambiguous verbs like "discuss" and "tell.“ 5. Will all or most all content experts agree that the scoring plan outlines the correct response to the item? 6. Will the scoring plan insure that your judgments on each essay are protected from bias? 7. Are all students aware of how the essay with be scored? 13 Thoughts to consider when you . . . Create Your Scoring System Essay Scoring Systems – Some Basic Choices 1. Point method - Have a written outline for yourself which expresses your preconceived model of a high quality answer (i.e. key points to be included or skills to be demonstrated). Simply sum these points. 2. Analytic method – use a two-way scoring rubric (e.g., rate on subscales from 1 to 4); raters break the essay task into important predetermined sub-tasks associated with key points and skills. 3. Holistic method – use a one-way scoring rubric (e.g., rate on overall scale from 1 to 9); raters compare each essay taken as a whole to the model. There is a variation to this method in which the raters sort all the essays into three categories (for example: “below average”, “average”, “above average”) then fine sort within categories. Some teachers use this method for A, B, C, D, F. 4. Primary Trait method – Used most often when the essay task is a practical one (for example, “Write a letter to your French pen pal.” The score is determined on whether it was complete or not; sometimes we say “met, or unmet”. The students receive a predetermined score when the task is completed satisfactorily. 14 Thoughts to consider as you . . . Score Individual Essay Items 1. 2. 3. 4. 5. 6. Have your scoring key or scoring rubric physically with you as you score. Prior to the start of reading your students’ essays, decide how to handle writing mechanics issues such as grammar, penmanship, spelling and punctuation. Evaluate one question at a time, avoid the "halo" effect of the first good/ or bad answer impacting future judgment. Don't look at student's name – “I know she knows, but she just didn't express herself.” OUCH or “How did he come up with this answer, he must have cheated.” DOUBLE OUCH One solution is to have students place their names on back of essay . . . of course, you may recognize their handwriting. Watch for the tricks of bluffing - name dropping; addressing the significance of problem but not its solution; making some great points but they are off the topic; just writing and writing and saying nothing. Use two or more raters if the decision based on this essay is critical. 15 Some overall thoughts on . . . Using Performance Task Assessment Certainly by asking students to take written exams we are interested in their performance, but we are thinking of performance a bit differently here. In performance task assessment we are interesting in having them do something other than paper and pencil testing. Performance testing can be standardized and they can have norms just like the paper an pencil tests. Most likely, however, you will create performance tests for use in your own classroom much as you create essay exams. So, the students are active in producing something. In fact, it might look like an instructional activity. It would distinguish itself from an instructional activity in that it would have an assessment component. As teacher, you might assess the process the student is using or you might assess the product. Or both. Assessing a performance task would have similar scoring issues as an essay, so look back at those guidelines. 16 Some Final Questions to Consider on . . . Performance Projects and Assessment Performance tasks, whether they be individual or group, have special questions to consider as we evaluate the products and processes associated with them, for example: How can I restructure the class period in order to give students time to work on the products? This time needed will expand if the projects involve group work. Is this taking away for important content I should be teaching? How can I restructure my class time so I can fairly assess both the process and the product. What will the rest of the class be doing while I am assessing the performance task (since, by the nature of these assessments, not everyone is “on stage” at once)? How can I be certain that tasks completed outside of my direct supervision were really done by the student? Certainly there is cheating on paper and pencil exams; but if work completed at home is a large percent of ones final score, I may be asking for trouble. 17 Using Constructed Response Items for . . . Formative Assessment The intent of this group of techniques is to collect data which will allow immediately redirect learning, if necessary. Authors Angelo and Cross (1993) used the unfortunate term “Classroom Assessment Techniques” (why unfortunate?) and it has caught on in the literature. It functions quite simply. At key points decided by the teacher, the students are asked for brief, written responses to open ended questions (some teachers like oral responses). Students are told their responses not be graded (as an alternative, the questions might be blanket scored with low point values). When written, 3 by 5 cards or even scrap paper might be used ; allow students 1-3 minutes to write. The teacher reviews the responses simply to see if the students “get it.” No rubric is used. Teachers can read these quickly and determine follow-up activities based on the cards. The next slide has examples of constructed response items that might be used in formative assessment. 18 Examples of Brief Constructed Response Items for . . . Formative Assessment WRITTEN (delayed feedback but private) Directed paraphrasing – Write the meaning of a key concept or term in their own words. Muddiest point – Identify the most confusing point discussed. Pro and Con Grid – Provide thoughts both for and against an idea discussed. Test Item – Prepare a test item appropriate for the topic. ORAL (immediate feedback but public) Lecture Pause - Teacher stops lecture at 1 or 2 key points and asks students to reflect on how they are feeling about what they are learning. After allowing reflection time call on a few students to sample the feelings. Opinion Poll - Teacher poses questions, students respond in unison by each holding up cards (Yes or No; A, B, or C). Notice this is really a selected response variation. Some schools use electronic clickers. 19 Practical Advice . . . To following when using construction response items. 1. Become proficient in, and use a mix of, both selected response and constructed response items. 2. Devise your scoring system in advance. 3. Make sure you are assessing your learning objectives and not extraneous skills. 4. If you are interested in assessing higher level cognitive skills, make certain that the range of anticipated responses is truly open-ended. If there is truly only one possible response, consider re-crafting the item as a selected response item . 20
