One of a number of tried and tested technique for teaching work that students find hard to learn found in teaching tricks and tips

accept

Accepting that learning of some topics will interfere with other topics is the first step to recovery

By accepting that leaning of some topics will interfere with the learning of other topics and embracing this - we are able to help the students decouple the ideas and the names attached to those ideas. 

When designing the lay out of the questions we ensure that the questions looked exactly the same apart from the essential key differences for example the word area or perimeter and the units on the answer line - so the student must focus on mastery, if for no other reason that they become "bored" by getting their answers wrong and then "challenged" to get the questions correct. 

We also encourage teachers to get students to reflect on situations where the student has succeeded in overcoming this confusion before such as "Remember when you used to be confused between area and perimeter and now you get these correct every time, well, I think it will be the same with  b x b x b and b + b + b"

This is more than just encouragement, the teacher is getting the student to recall the "feeling of pride in a job well done" and establishing both the student and the teachers belief in a "growth mindset". 

The plan for this page is to build up examples as above and include links to "teaching Higher work to Foundation students" videos and more easy on the eye student "remind-me" videos. For now though here is a list of situations where we have found asking students to focus on the difference between two problems has helped.

Here are a number of problems that will interfere with each other initially

simplify

Once we start to teach how to simplify h x h x h x h students lose their confidence  in knowing that h + h + h + h = 4h  .... so as soon as you teach h x h x h x h get students to work on and compare with h + h + h + h type problems, ideally in a mixed bag over time.

area AND perimeter

With two concepts are ubiquitously confused by students such as area and perimeter, we know that after teaching one carefully - to what seems like mastery - when the other is introduced most students will become confused. We encourage students to embrace this confusion and encourage them to self reflect 

• if this question was about finding the area - what would I have to do?
• if this question was about finding the perimeter - what would I have to do?

and then finally to think

• OK this question is area - perhaps use the clue on the answer line " .... m²  - so I want to work out the number of squares" - to give their answer confidently

If students believe that most people run into the confusion that they have encountered, and that there is a logical way through the problem, and that a pause for thought leads to an accurate answer and most importantly the students encounter as many instances in their timely practice assignments as required to accurately match the name of the concept with the concept then the teaching and learning process will succeed.

factor AND multiple

Teach multiple typeOFnumber1.pdf but as soon as you begin to teach factor compare the two typeOFnumber2.pdf and give a hint of how to distinguish.

all the factors of ... AND write ... as a product of its prime factors

Personally I like to teach students to write a number as its prime factors before I get them to find all the factors of the number.
