The issue of political polarisation and bias in classrooms is a time-honoured one, having been an issue as old as the profession itself. Students, parents and the community, at times understandably, have been weary of teachers being biased and partial in the way they approach contentious issues in the classroom. These concerns are particularly relevant in Humanities classrooms, which deals extensively with societal issues and debates. Recent political events, including elections and terrorist attacks and the resulting divisive discussions and rhetoric, have only further enhanced these issues and concerns. As Humanities teachers, it is crucial that we naviagate these issues with students in an even-handed, calm and thoughtful manner.
Such concerns around ideological diversity and debate in classrooms have been heightened for a number of reasons. One of these are widely-reported protests on college and university campuses across Western countries, Australia included, in which speakers are de-platformed, shouted down or otherwise prevented from speaking freely. Ongoing research has shown that there is a lack of ideological diversity on campuses. A report from Heterodox Academy, an organisation led by social psychologist Jonathan Haidt which seeks to increase ideological diversity in academia, shows just how pervasive the problem is. Data shows from the report shows that at some colleges, there is a ratio of more than 10 faculty members identifying as liberal or left-of-centre for every conservative or right-of-centre member of faculty. Although less often mentioned, there is also a problem with ideological diversity in primary and secondary classrooms.
When teaching Humanities subjects at a Secondary level, it is important to remain impartial and not push an agenda onto students. As teachers, we are rightly mindful of diversity in terms of gender, race and so on. At times, however, the profession fails to promote ideological diversity. Too often, classrooms can resemble echo chambers, where only a narrow set of views and opinions are discussed and explored. There are a few reasons why this is the case. One of the main reasons for this, unsurprisingly, is that school classrooms generally reflect the ideological viewpoints of the community in which they are situated (Hess, 2009, p.6). By extension, teachers may, without realising, internalise the dominant viewpoints of the school community in which they are a part of.
In order to cultivate ideological diversity in the classroom, at a minimum, clear, effective and strong principles of classroom and behaviour management must be implemented. Students speaking and voicing an opinion must be able to talk uninterrupted, even when raising points which may go against the consensus thinking of the classroom or may be controversial in some way. It is also essential to model to students how to respond, in terms of what constitutes and appropriate and inappropriate response to challenging ideas. It must be made abundantly clear, for example, that personal insults or denigration are completely unacceptable and that clear consequences will occur for students who violate this basic classroom expectation.
In order to do this effectively, a significant level of introspection and critical reflection on our teaching practice, particularly our manner of communication is necessary. At times, this will require also reflecting on our own belief systems, political beliefs and so on. Research has found that teachers who are willing to explore confrontational and controversial issues with students implicitly encourage students to do likewise (Hess, p.6). In order to teach students the skill of civil discussion on complex and contentious issues and encourage diverse viewpoints on them we as teachers must model these behaviours ourselves. This means conducting ourselves in a professional manner, not only in the classroom but in other avenues where such topics may come up, such as social media. In the same way we must avoid our classrooms becoming merely ideological echo chambers, we must avoid falling into similar habits when discussing contentious issues online or in person outside the classroom.
