Mixed‐Ability versus Own‐Choice Pairs

The Three‐minute Reasoning Test a Re‐evaluation

“…Experiment One in this paper was a replication of this experiment, except that in this study one group of pupils chose their own partners to work with through the programme, and in a second group partners were formed by the teacher. (Since there was no significant difference between the results obtained from the two groups -see Hogarth and Hartley (1973)-the data have been pooled in the investigation to be reported here.) In addition, in this study, a change was made in that the time allowed for the Threeminute Reasoning Test was extended to four minutes, and pupils indicated, by drawing a line across the page, which point they had reached after the third minute.…”
