When I run a cyber-dojo
I always ask the participants to work in pairs, two people per computer.
I've been doing some research on pairing and I've come across a book called
by John Hattie. It's a synthesis of over 800 experiments and papers relating to achievement in schools.
On page 225 there is a section called The use of computers is more effective when peer learning is optimized
It reads, and I quote...
- Lou, Abrami, and d'Apollonia (2001) reported higher effects for pairs than individuals or more than two in a group.
- Liao (2007) also found greater effects for small groups (d=0.96) than individuals (d=0.56) or larger groups (d=0.39).
- Gordon (1991) found effects were larger for learning in pairs (d=0.54) compared to alone (d=0.25).
- Kuchler (1998) reported d=0.69 for pairs and d=0.29 for individuals.
- Lou, Abrami, and d'Apollonia (2001) reported that students learning in pairs had a higher frequency of positive peer interactions (d=0.33), higher frequency of using appropriate learning or task strategies (d=0.50), persevered more on tasks (d=0.48), and more students succeeded (d=0.28) than those learning individually when using computers.
What do the numbers mean? Quoting from the front of the book...
An effect size of d=1.0 indicates an increase of one standard deviation on the outcome - in this case the outcome is improving school achievement. A one standard deviation increase is typically associated with advancing children's achievement by two to three years, improving the rate of learning by 50%, or a correlation between some variable and acheivement of approximately r=0.50. When implementing a new program, an effect size of 1.0 would mean that, on average, students receiving the treatement would exceed 84% of the students not receiving that treatment.
Of course, things are rarely absolutely black and white, but these are impressive numbers.
