The development of critical thinking (CT) skills is widely recognised as one of the most important aims of education. In the language classroom, CT poses a particularly demanding challenge. Language mastery plays a key role in reasoning, as anyone who has attempted to argue cogently in a foreign language can attest, and we should not underestimate the difficulty of displaying critical thinking as a non-native speaker. In this regard, CLIL offers teachers and students a valuable opportunity since, under the popular 4Cs model, language learning goes hand in hand with content and cognition (Coyle, Hood & Marsh, 2010). They can proceed in step with one another, so that as students deepen their knowledge of content, they correspondingly develop both their language and thinking abilities.

So, what is critical thinking and how can it be taught in the CLIL classroom? To answer these questions, it is useful to turn to taxonomies of critical thinking that attempt to break this rather amorphous concept down into specific teachable skills. Bloom’s seminal work of 1956 identified six major cognitive categories, which have provided the basis for future taxonomies. Ennis (1987), for instance,set out a list of twelve key abilities: focusing on a question, analysing arguments, asking and answering questions of clarification, judging the credibility of a source, observing and judging observation reports, making and judging deductions, making and judging inductions, making value judgments, defining terms, identifying assumptions, deciding on an action, and interacting with others. Following this, Facione (1990) came up with six broad categories of interpretation, analysis, evaluation, inference, explanation, and self-regulation with each category further broken down into sub-skills. In more recent years, Anderson and Krathwohl (2001) added a Knowledge Dimension to these lists, referring to the skills we need in order to understand, interpret and apply content knowledge. This has made it a particularly valuable resource for CLIL curricula (Coyle, Hood & Marsh, 2010).

While such taxonomies of skills have not been universally accepted (Norris, 1992), the advantage they offer to CLIL teachers is that they provide a framework in which CT can be taught in an explicit and deliberate fashion. There can be a tendency in academic courses, language or otherwise, to assume that critical thinking is being developed even when learners are not carrying out activities specifically designed to improve their thinking skills. For example, directing students to discuss the content they have been learning might exercise their thinking faculties to a degree, but without some way to monitor and improve the quality of such discussion, the effect may be limited. Likewise, in a CLIL project we might have our students gather and present information on a topic; however, unless we show them how to gather information effectively, how to evaluate it for reliability, how to root out bias and unsupported opinion, and how to draw up well-reasoned arguments, we might simply be reinforcing sloppy habits.

Teaching critical thinking explicitly as a set of discrete but closely interrelated skills might not necessarily lead to better thinking. There is a perennial debate in the literature about how well CT skills transfer from one academic context to another (Moore, 2011). However, at the very least our learners will come out of the course with a clear understanding of what CT entails and how it can be applied to their work within and beyond their academic studies. In a country like Japan, where critical thinking as a term is little used and its importance rarely emphasised at most levels of schooling (Amano 1999), this is a worthwhile objective.
