Numeracy Rubric Outcomes • Analyze a given problem • Select a Model • Solve the problem • Review Results • Make Inferences
1. Analyze the problem • Formulate a question, or • Identify relevant information, or • Identify missing information, or • Find additional information needed, or • Restate question in own words
2. Select/Develop a model • Accurately represent the data or information given in the problem using • Graph • Chart • Equation • Formula • Spreadsheet • Picture • Other
3. Solve the problem • Get a correct answer • Include correct units if applicable
4. Review results • Is the answer reasonable? • Is there more than one correct answer?
5. Use the model • Make an inference about reality • Choose a best course of action based on results • Discuss the meaning of the answer in relation to the real-life situation
HYPOTHETICAL PROBLEM • What is the total blood volume of a 6-lb infant? • 300 ml
HYPOTHETICAL PROBLEM • What is the total blood volume of a 6-lb infant? Show your work. • 6 lbs = 3 kg, and 3kg (100 ml)/(1 kg) = 300 ml, so Answer: 300 ml
HYPOTHETICAL PROBLEM • What is the total blood volume of a 6-lb, 15-inch-long infant? Show your work. • 6 lbs = 3 kg, and 3kg (100 ml)/(1 kg) = 300 ml, so Answer: 300 ml
HYPOTHETICAL PROBLEM • What is the total blood volume of a 6-lb, 15-inch-long infant? Show your work. Is your answer reasonable? • 6 lbs = 3 kg, and 3kg (100 ml)/(1 kg) = 300 ml, so Answer: 300 ml Yes, it’s reasonable for a 6-lb baby to have 300 ml of blood.
HYPOTHETICAL PROBLEM • What is the total blood volume of a 6-lb, 15-inch-long infant? Show your work. Is your answer reasonable? • 6 lbs = 3 kg, and 3kg (100 ml)/(1 kg) = 3000 ml. Something’s not right. 3000ml is 3 liters, one-and-a-half of those 2-liter bottles of soda. A 15-inch baby can’t have that much blood.
HYPOTHETICAL PROBLEM • Terry has been told to collect blood samples on a 6-lb, 15-inch-long infant in the ICU nursery. She is to collect 2 cc’s for hgb and 2 cc’s for lytes. After she completes the draw, she must record on a clipboard the total amount of blood collected and what percentage the sample is of the total infant body weight. What should Terry do? Show all work, and discuss the reasonableness of your answer.
HOW TO SUBMIT A NUMERACY SAMPLE • Choose a single problem from a test, in-class assignment, final exam, homework, or project, which requires the student to demonstrate as many of the five competencies as possible.
HOW TO SUBMIT A NUMERACY SAMPLE • When you have the chosen problem for an entire class set which has been graded, one from each student who completed the assignment, call Kory Merkel at x5-7673, and she’ll come make copies.
HOW TO SUBMIT A NUMERACY SAMPLE • Have a key to the chosen problem available. Evaluators are from many different disciplines and may not know your specialized math application.
IF YOU NEED HELP . . . Pleeeeeze call Kory Merkel at 285-7673, and she’ll be happy to trouble-shoot on the phone, or to come by your office at your convenience.
