Thinking critically : a look at students' critiques of a research article

Abstract

The ability to reason, analyse, and evaluate issues critically is a valued skill, and ranks highly in the list of attributes expected of graduates. Much has been written about the importance and application of critical thinking in various domains, but studies on the actual manifestation of such skills in students’ writing have attracted only modest interest. Even less has been written about critiques in relation to critical thinking. This study sought to investigate the form and nature of issues raised by 119 second-year biology undergraduates in their critiques of the introduction section of a research article. The study revealed that the vast majority of students tended to raise surface issues in their critiques, focusing on visible textual features such as rhetorical structure and language-related issues. The minority who raised depth issues addressed the arguments used in the reading and their significance. In light of the skewed results, a two-stage process — involving (1) summary writing, and (2) the use of evaluative criteria and the Toulmin model as an overarching framework — is recommended to enhance the teaching of critical thinking within the curriculum. This study offers a glimpse into the outcomes of critical thinking, as represented by the students’ critiques. It provides a bottom-up approach to our understanding of the issues raised by students in a task centred on critical thinking, and so focuses our attention on specific areas for further consideration or remediation.
