Constructed Response Questions Develops the reasoning faculties of the student What is a Constructed Response Question? • CRQs are open-ended, short answer questions. • As the name suggests you have to construct your own responses to answer these questions. • Your answer to each of these questions could be in a few words or a few sentences depending on what is being asked. • Answer to CRQs may require more than simply recall facts. You may have to apply your knowledge to certain situations, analyze information or solve problems. What are CRQs? • They use a range of primary and secondary stimuli, and authentic „real world‟examples including maps, graphs, charts,etc. • CRQs are based on learning objectives (SLOs) and build from simple to complex. • They are composed of defined tasks. • They are graded against specific criteria. CRQs project to achieve the aims of AKU-EB • • • • • Develop an ability to think scientifically Acquire an ability to perform experiments Acquire an ability to solve problems Observe accurately and objectively Develop imaginative and critical thinking Targeted skills of CRQs • CRQs aim to assess understanding of factual knowledge ability to synthesize ideas into an explanation ability to select evidence to support ideas ability to analyze a graph, diagram, etc. • CRQs are based on knowledge, understanding, application, problem solving, practical activities and data handling. What do CRQs ask the student to do? • CRQs usually begin with words such as , explain, describe, interpret, construct or develop. • You may be required to compare and contrast, show cause and effect, identify patterns, construct graphs or charts, summarize information, state a conclusion or predict based on evidence presented. Strengths and Weaknesses of Constructed Response Strengths • Can assess complex outcomes • Closer to and cheaper than “authentic” or “performance” assessment • Mastery Manager may be used to do item analysis Weaknesses • Harder to score than selected response • Takes more time to sample the content • Good rubrics needed to minimize subjectivity How to develop CRQs • Clearly define the intended learning outcome (specific learning objective – SLO) to be assessed by the item. • Avoid using constructed response questions for SLOs that are better assessed with other kinds of assessment. • Clearly define and situate the task within a problem situation. Steps in Creating a Constructed Response Item • Establish the target. • Select the component part(s) of the target to be included. • Prepare the constructed response prompt or exercise. • Identify the material. • Specify the kinds of reasoning or problem solving to be accomplished. • Point the way to an appropriate response • Devise scoring criteria. How to answer CRQs • The most important thing is to understand the question. • Give them what they want! • Answer all parts of the question. • Include right specific details in support of your answer. • Think, organize and construct. • Write your response clearly, concisely and coherently. Tips for answering CRQs • Read the constructed response question very carefully. • Examine the information provided. • Identify key words. • Highlight or underline things you are asked to do, statements like: Explain the main idea….. Use 3 examples to illustrate…. • Write your response coherently and succinctly. Checking Your Constructed Response Items • Try answering your own item – are instructions and expectations clear? • Draft your idea of a “very good” response and design a rubric. • Think in percentages or letter grades instead of points (e.g. 5 out of 10 = 50% - a failure!). • Use “zero credit” sparingly - is the work really the same as a blank paper? (Yep, sometimes it is!). • Can you help students “format” or “check over” their responses? Do‟s and Don‟ts for Constructed Response • Don‟t use constructed response items to assess individual knowledge targets. • You can ask more selected response items in the given time period. • You can assess a broader sample with selected response. • You can score selected response faster. • Don‟t offer choices. • Can you hit the target? NOT, Which part of the target can you hit? • Students waste precious time making the choice. Do‟s and Don‟ts for Constructed Response (Continued) • Do use constructed response items to assess larger units with smaller related elements. • Do use constructed response items to assess Reasoning (note: the situation presented should be “new”). • Do consider doing this type of assessment prior to finals week with feedback occurring during finals week. The marking criteria of CRQS • Specify the marks allocated for each question or part. • State the grading criteria. • Use several short questions rather than one long one. A CRQ with marking criteria • The energy requirements for a human body are 50% carbohydrates, 35% fats, and 15% proteins. a) Why do we need fats? Give two reasons. b) What will happen if we take less carbohydrates in our food? Identify two effects. (4marks) Mark Scheme • a) 1 mark for each reason. Fat is a very concentrated source of body energy. We need fats because i) They provide soluble vitamins A,D,E & K and as much good sources of vitamins like full cream milk, cheese and eggs. ii) They provide essential fatty acids which we need like linoleum acid and alpha-lanoline acid. • b) 1 mark for each effect such as i) Starchy food is very absorbent and holds a lot of water which makes content of the bowel soft and are easily passed out. Reduced intake will cause constipation and may cause cancer. ii) Diverticular disease and hemorrhoids are also caused by low intake of carbohydrates and starchy foods
