The Impact of IMPACT: How instruction in critical thinking has a beneficial impact on standardised test performance
Critical and creative thinking are fundamental 21st century skills and ‘general capabilities’ or ‘core competencies’ of many educational systems around the world, and yet there is much confusion and indeed some doubt about whether explicit instruction in critical thinking is either necessary or desirable. Standardised testing, meanwhile, is under fire for encouraging teachers to ‘teach to the test’ in a way that, for many teachers, undermines their capacity to create opportunities for students to engage in critical and creative learning. This study, based on an examination of standardised test (NAPLAN) performance data from students enrolled in courses dedicated to the teaching of critical thinking through the Queensland Government Department of Education’s IMPACT Centre shows that explicit instruction in critical thinking is correlated with significant relative gains when those students are compared with students whose exposure to critical thinking was secondary to domain-specific knowledge. This promises (a) to provide reasons for thinking that explicit instruction in critical thinking is beneficial for students in supporting the core areas of the curriculum measured within standardised tests, and (b) to provide an antidote to the idea that the existence of standardised testing militates against inquiry-based, critical thinking pedagogical practices.
