Which is the correct match?

How did you solve this problem?

The Concrete Operational Stage
• Operations refer to logical thought processes. These include:
• Conservation
• Reversibility
• Seriation
• Transitivity
• Class inclusion
Seriation and Transitivity
• Bob is taller than his sister Katie. She is taller than their other sister Rachel
• Put these children in order of height:
• Bob  Katie  Rachel (seriation)
• Is Bob taller or shorter than Rachel?
• Katie is taller than Rachel, Bob is taller than Katie therefore Bob is taller than Rachel (transitivity)
Odd one out
• How did you decide which was the odd one out?
• Why is it that we can have more than one correct answer to this problem?
Class Inclusion
• Piaget & Szeminska (1941)
• 20 wooden beads: eighteen brown, two white

Three questions:

• Are the beads all wooden?
• Are there more brown beads or white beads?
• Are there more brown beads or wooden beads?
• What sort of error do you think an 8-year old might make on this task? Why?
Class Inclusion: Piaget & Szeminska (1941)
• Questions 1 & 2 require an understanding of two separate classes of objects
• Question 3 requires an understanding of overlapping and super/subordinate classes (e.g. brown beads are also wooden beads)

Errors in this task suggests the child may still not be able to decentre; they can only think about one aspect of an object (in this case class) at a time

Donaldson (1978)
• Three black and one white cow, all lying down ‘sleeping’.
Donaldson (1978)
• 6 year-olds asked:
• Are there more black cows or more cows?
• Are there more black cows or more sleeping cows?
• Do you think there was a difference in the number of correct responses? Why (not?)
Homework
• Look at the Toys R Us website (www.toysrus.co.uk) and pick a toy that you think would be suitable for a child aged anywhere from 2-11
• Design an advert for the toy, aimed at parents interested in pushing their children
• Make sure you explain what cognitive features the toy will help develop
