The ability to solve problems and think critically are considered by many to be desired outcomes of the education system, both within K-12 and higher education. They are ever-present skills measured by many accreditation frameworks in the professional and higher education sectors, and consistently rank among the top skills and abilities desired in graduates, according to employer surveys (Hart Research Associates, 2008; 2013). Despite this prevalence, critical thinking and problem solving are often identified by employers as skills that require more emphasis in higher education (Hart Research Associates, 2008; Arum & Roksa, 2011). Recent evidence questions the degree to which current undergraduate education supports the development of critical thinking and complex problem solving skills (Arum & Roksa, 2011; Astin, 1993a; 1993b; Blaich & Wise, 2008; Klein et al., 2009; Pascarella, Blaich, Martin & Hanson, 2011). The development of critical thinking skills (CTS) is itself a complex issue, complicated by a lack of agreement on the definition of critical thinking and on an associated framework for its development (Ku, 2009). Popular frameworks of critical thinking include the Cornell-Illinois model (Ennis, Millman & Tomko, 1985), the Paul-Elder model (Paul & Elder, 2005; Paul & Elder, 1996), the CLA model (Shavelson, 2008), the APA Delphi model (Facione, 1990), and Halpern’s Model for Critical Thinking (Halpern, 1999; Halpern & Riggio, 2002). Each of these frameworks or models proposes a different definition for critical thinking and a different set of skills, traits and abilities that comprise it. Instruction and assessment of CTS is also an area of particular difficulty, with the efficacy of pedagogical strategies for critical thinking development and the authenticity of critical thinking assessment under much scrutiny (Bensley & Murtagh, 2011; Solon, 2003).
