Performance of the adaptative algorithm in ensuring a defined level of success. Children's average mean success at each trial in the software study (measured as a running average of the last 20 trials for each child, and averaged across all nine participants). This gives an indication of how well the software adapted to children's performance, i.e. how well it stayed at the desired mean success rate of 75%. We can see that for the first half of the remediation, mean success was higher than 75%, but it eventually converged close to this value.
