This study addresses an issue of global concern in skills training, namely, the rapid and permanent eradication of persistent habit errors, and bad or unsafe working practices. This article offers an alternative human factors explanation for the profound difficulties and low transfer of training experienced during error pattern retraining, and the correction of habitual performance faults. It describes "Old Way New Way," a metacognitive strategy for achieving rapid and permanent error and technique correction and habit unlearning, and presents the results of an experimental trial of this behaviour change methodology. Vocational education students, representing a broad range of skill types, were recruited and randomised to one of two error correction modes, or to a control group. One "Old Way New Way" correction session with students yielded 80% or higher performance improvement that was maintained over three post-test periods. Students and teachers reacted positively to the "Old Way New Way" learning method. The high level of transfer of learning obtained is consistent with results in other settings. Implications for education, training, coaching and other performance enhancement settings are discussed. (Contains 1 figure and 2 tables.)
