The arguments for…

  1. In higher education, learners are predominantly adults with a clearer idea of what they wish to learn compared with children. According to the adult learning theory devised by Malcolm Knowles in the 1960s that popularised the term ‘andragogy’ (vs ‘pedagogy’), one characteristic of adult learners’ motivation is the willingness to learn when the subject matter is relevant to their perceived needs. In this regard, differentiated instruction (DI) offers an advantage in that, amongst the repertoire of DI strategies are some which differentiate content of learning for individual students. As an example, following a pre-test of relevant knowledge, lecturers can ‘curriculum compact’, i.e. excuse a learner from studying particular content because they have already exhibited sufficient mastery, thus buying time for them to acquire other knowledge. A second DI strategy that applies here is the ‘learning contract’, the negotiation of which factors in a student’s needs and interests. So, DI does offer a range of techniques to tailor courses for individual adult learners.
  2. At colleges, polytechnics and universities, student populations are often highly diverse. Besides readiness, interest and learning profiles (Tomlinson, 2005), there are numerous other factors that distinguish students from each other:
  • nationality
  • physical disability
  • specific learning disorder, e.g. dyspraxia
  • age
  • gender
  • socioeconomic status
  • ethnicity
  • religion
  • mode of study, e.g. part-time
  • etc.

In this situation, it can be argued that the question is not whether such diversity should be catered for but how it should be catered for, and DI is a rare example of a systematic yet versatile response that is available to higher education lecturers.

  1. Educators in higher education can draw confidence from the insights gained by researchers who have looked into the impact of DI in school-level education. There have been positive findings about the effect of DI on motivation, for example. (For a list of key findings about DI, see my blog entry on the topic.) Although it may be retorted that primary and secondary level education is not sufficiently relatable to higher education, it is interesting to note that in other areas, research discoveries from elementary and high school education are highly respected at university level, e.g. Black & Wiliam’s seminal work on the effectiveness of formative assessment.
  2. There have been some experiments with DI at tertiary level with positive results. As an example, Ernst & Ernst (2005) reported that “students generally responded favorably to the differentiated approach, reporting higher levels of intellectual growth”.

The arguments against…

  1. Another assumption about adult learners in Knowles’ andragogy theory runs counter to the one of the main tenets of differentiated instruction. Adult learners, says Knowles, need to be self-directed in their learning whereas in DI, the person making decisions about learning is usually the instructor, with some input from learners. Since DI was developed for younger learners, the element of control by teachers is stronger than one would expect to encounter in university settings.
  2. There have been some experiments with DI at tertiary level with negative results. In the same paper, Ernst & Ernst (2005), flags were raised about the increased time commitment needed to implement DI and it was reported that “instructor’s concerns related to the fairness of the approach”.
  3. There are alternatives to DI such as Universal Design for Learning and the increased use of Technology-Enhanced Learning in order to accommodate individual learning differences.
  4. Compared with school teachers, university lecturers may not always know their students that well. This is because student cohorts may be large, contact hours may be lower, and students may go AWOL from time to time. If the lecturers are not that well informed about the learners, then any attempt at differentiated instruction would be based upon assumptions. By contrast, primary/elementary school teachers will have much greater opportunity to find about their learners and therefore apply DI more meaningfully.

So, what to do? Adopt or ignore DI?

As I have proposed in another blog entry, entitled Can differentiated instruction lead to self-directed learning?, I suggest that DI could serve as an interim measure in higher education. There may be many university students who are already self-directed but, given the increased access to higher education compared with a generation ago, it is reasonable to suppose that a more directive approach such as DI could be appropriate on occasion and for particular learners.

One thought on “Does Differentiated Instruction belong in higher education?

  1. Then there’s the other factors that go into DI – teachers’ self-efficacy, institutional values, fidelity of implementation (which feeds in to any number of factors), and so on. Some instructors are overwhelmed by it and would stop trying, some see it a challenge and forge ahead anyway. There’s a whole lot of research on student and teacher sides of the issue, particularly in the sciences.
