Newman's Error Analysis
Newman's Error Analysis
When answering a written maths problem, you must pass through series of steps. These are...

Process Skills
5 Newman Questions
1. Please read the question to me

2. Tell me, what is the question asking you to do?

3. Which method do you use to get your answer?

4. Show me how you get your answer, and 'talk aloud' as you do it, so that I can understand how you are thinking.

5. Now, write down your actual answer
Reading - can not read word or symbol and prevents him/her from moving on

Comprehension - not grasping meaning of the words

Transformation - unable to identify the operation or sequence of operations

Process Skills - did not know procedures

Encoding - could not express the solution in acceptable written form
How we can assist

* provide orientation to problem.
Make students aware of the story, context, unusual language, maths words in problem
* work with reading partner
* have maths word charts displayed in room

* do not read out problem or give too much guidance
How we can assist
* focus on vocabulary and text features
* discuss cloze passages
* reassemble texts

* focus on solving problems
* teach students to represent problems
* teach students to write problems
* rewrite the problem removing distractors
How we can assist
*Ask: What do you need to know to be able to work out the answer?
* Make list or diagrams that are associated with a process

* Encourage re-read of question and compare to answer
* Have you used correct units?

Where students go wrong
Looking for key words and ignored key meanings
Trying different mathematical operations with our direction
Not reading the problem carefully
Reading the problem too quickly and cursorily
inability to read the problem
Not considering the context of the problem
Failing to check reasonableness of the answer
Little perseverance with a question
Failing to access any problem solving strategies
Celebrity Heads
Give a student a number between 1-300 and tell them they have 10 questions to determine the value. The class may respond with higher or lower or other responses. Observe the strategies that are applied to solve the problem.
* Make a list or table
* Work backwards
* Act out the problem
* Look for a pattern
* Draw a diagram or graph
* Guess and check
* Use materials
* Think of a similar problem
* Estimate and check
Doing fifty standard problems from a textbook or worksheet will not promote the thinking that is required from students, neither will a standard 'chalk and talk' teaching lesson.
