Despite extensive discussion on critical thinking (CT) by Chinese students, there are still debates over the question of why Chinese higher education students, when studying abroad, lack (or rather do not demonstrate) CT skills. The main objective of this paper is to explore how far it can be established from the published research literature whether the key factor affecting Chinese university students' CT with respect to academic study in English is cultural background or previous training. The conclusion is that culture cannot be the sole explanation for Chinese students' CT performance at universities abroad. The evidence strongly suggests that, while CT elements can indeed be found in ancient Chinese culture, many other factors, especially students' previous learning experiences, are of more immediate relevance and likely to affect performance. As a result, a holistic approach is suggested. The review also suggests that there is at times a lack of clear definitions and/or explanations of the scope of the key concept - culture - in the current literature.[Copyright of Routledge.
