Question 2 Flashcards
What is the difference between formal and informal algorithms
Provide example for each one
(34 x 46)
Informal algorithm
Personal/ individual way in which a problem is solved
(30 + 4) (40 + 6)
1200 180 160 24 1564
Formal algorithm
Method in which the majority of the population uses to solve problem
A detail set of instructions to produce a specific outcome
Automatic being able to be taught to, carried out by someone who doesn’t have to analyse deeply
For teacher algorithms are easy to teach students
What are the advantages and disadvantages of teaching the formal algorithm to students
Algorithms do not correspond to the way people think about numbers
They encourage children to give up their own thinking leading them to lose their own ideas about how to solve the problems
Students are more likely to use calculator then that of in the past could lead to traditional taught algorithms being less effective at teaching students maths
Students use algorithms within problems which don’t need algorithms
Why does Clarke recommend delaying teaching algorithms to at least 4th grade
Do you agree
Stops students to develop their own ideas into how to solve the problems leading the technology to be dependent on step on step procedures to solve problems
Helps develop their understanding for numbers
I agree
