Committing errors is an inevitable part of learning, particularly when students encounter novel or difficult topics in Mathematics. While many educators doubt the benefits of using errors in learning, researches on the human brain claim that errors increase the brain’s neural activity and forms new neural synapses, suggesting that learning has occurred. Hence, utilizing errors as formative aids
... [Show full abstract] for learning can be advantageous to the learners. This study assessed the effects of E.R.R.O.R.S. Strategy on students’ mathematical understanding and error-culture perception. The results suggest that the strategy improved the learner’s mathematical understanding and error-culture perception. Specifically, the students taught using this strategy outperformed the students taught using the conventional method. Moreover, the positive and significant changes on students’ error-culture perception based on error-friendliness, missing transparency of norms, learning orientation and error anxiety were observed. Furthermore, correlations between error-culture perception and mathematical understanding were established. It was found out that error friendliness and learning orientation have positive correlations to mathematical understanding while missing transparency of norms and error anxiety have negative correlations. The results of this study verified that errors can be productively used to improve mathematical understanding and to foster positive error-culture. This study also highlighted the importance of having the skill of using errors to enhance the teaching and learning process and to promote a positive error-culture.
