Key research findings about Differentiated Instruction

A model of differentiation like Carol Ann Tomlinson’s (click here for more information) contains numerous instructional strategies which may be employed independently or in concert and in many possible combinations. This makes such a model very difficult to research and evaluate. Saying that, below are some fairly recent findings that I found interesting, and I hope you will, too.

Tiered ability grouping combined with differentiated learning materials increases the gap in achievement between lower and higher ability students.

Lower ability students’ achievement is enhanced through collaboration with higher ability classmates.

Schofield, J.W. (2010). International evidence on ability grouping with curriculum differentiation and the achievement gap in secondary schools. Teachers College Record, 112(5), 1492 – 1528.

The concept of ‘learning styles’ is insufficiently clear or evidenced, and therefore should not be a deciding factor when differentiating instruction.

Landrum, T.J., & McDuffie, K.A. (2010). Learning styles in the age of differentiated instruction. Exceptionality, 18(1), 6 – 17.

Differentiated Instruction has a positive effect on student engagement and motivation.

Educational technology shows promise as a means to make the differentiation of instruction and provision of individualised formative feedback more feasible and practical.

Scalise, K. et al. (2007). Adaptive technology for e-learning: principles and case studies of an emerging field. Journal of the American Society for Information Science and Technology, 58 (14), 2295 – 2309.

Many teachers report that they lack “the time, the skill and the will” to utilise DI strategies. This situation could be ameliorated through support from curriculum developers and publishers of educational materials.

Hertberg-Davis, H. (2009). Myth 7: Differentiation in the regular classroom is equivalent to gifted programs and is sufficient: Classroom teachers have the time, the skill, and the will to differentiate adequately. Gifted Child Quarterly, 53, 251-253.


Can Differentiated Instruction lead to Self-Directed Learning?

My question in this entry is whether Differentiated Instruction (DI) can be justified for the opportunity it offers to kick-start and scaffold the process of becoming a self-directed learner.

Differentiated instruction (DI) comprises a set of instructional strategies that teachers employ selectively to address the diverse learning needs of students. For a more complete account, kindly click here.

DI is controversial. For example, consider this quotation from Colin Everest: “Differentiation is just another pressure meted out by managers… Apparently I must use a variety of methods at every turn and I must present every topic through a variety of methods and approaches.” It can create an extra burden for teachers and so needs to be justified with compelling evidence that it is a worthwhile investment of teachers’ energy and time, and compares favourably with alternative approaches in terms of impact on learning.

However, leaving that debate aside, I propose that DI may merit consideration because of its relatedness to Self-Directed Learning (SDL).

In adopting DI, a teacher proactively plans varied approaches to…

  • what students need to learn,
  • how they will learn it, and
  • how they can express what they have learned

…in order to increase the likelihood that each student will learn as much as he or she can as efficiently as possible.

(Tomlinson, 2003)

By analogy, I contend that, in becoming self-directed a learner takes charge of…

  • what s/he needs to learn,
  • how s/he will learn it, and
  • how s/he can express what s/he has learned

…in order to increase the likelihood that s/he will learn as much as s/he can as efficiently as possible.

My portrayal of SDL is not too distant from Knowles’ (1975) definition of it as “a process by which individuals take the initiative, with our without the assistance of others, in diagnosing their learning needs, formulating learning goals, identifying human and material resources for learning, choosing and implementing appropriate learning strategies, and evaluating learning outcomes.”

In both DI and SDL, the element of choice is central, and informed choice at that. The difference is that in DI, it is the teacher making choices, and in SDL it is primarily the learner’s responsibility.

To make effective choices, the teacher or learner needs to be aware of the learner’s…

  • readiness to learn at particular levels of challenge,
  • degree of interest in learning topics,
  • background factors such as culture, gender and educational heritage, and
  • (more controversially) learning styles.

Following the learning, there is reflection and evaluation by the teacher and learner, and adjustments to future learning are made as a consequence.

I envisage teachers using DI in the early years of instruction, with the teacher making their decisions transparent to learners, followed by progressive transfer of control to learners as the students advance through their school careers. Perhaps in the last years of secondary/high school, the learners may be making most of the decisions about their own learning, thus exercising metacognitive skills prior to entry to higher education or the workplace.

Here is a very simple depiction of what I am imagining:


Do you think this is worthwhile exploring or researching? I welcome reactions….

Learning style inventories: Dubious, but useful for learner training anyway?

Learning style theory seems to be on the defensive.

For example, this 2007 article raised questions about the VAK (Visual-Auditory-Kinaesthetic) classification of learners: http://www.telegraph.co.uk/news/uknews/1558822/Professor-pans-learning-style-teaching-method.html . Reference is made in the same article to Frank Coffield’s January 2004 review in the Times Higher Education Supplement , in which he cautioned against using learning style inventories to “differentiate between students” and questioned the wisdom of using results from inventories to inform decisions about teaching.

Personally, I have always been wary of learning style inventories; the lower quality ones remind me of horoscopes in that they create the Forer Effect. Nonetheless, as stimuli to provoke reflection on learning strategies, I believe that they might have a positive application, which I will now describe.

I asked two groups of Form 6 students in Hong Kong (ages 16/17) to try the free, online Index of Learning Styles Questionnaire (ILSQ) at http://www.engr.ncsu.edu/learningstyles/ilsweb.html This generated results like the one below:

Balanced between ACTIVE and REFLECTIVE
After students had been assisted to understand their ILSQ results, they discussed the following questions:
  • Do you agree with your ILSQ results?
  • Do you think your learning style is fixed?
  • Does your learning style explain why you are better at certain school subjects?
  • Can knowing your learning style tell you how to study better?

Following this, the students completed a task to select learning strategies, according to their intuition, that suit them best. Finally, it was revealed which strategies matched which of the ILSQ styles, and students could compare their intuitive responses with the strategies recommended according to their ILSQ results.

The above process forced students to reflect on their preferred ways of studying and exposed them to alternative strategies. For these reasons alone, it seemed worth doing, even though the ILSQ has design weaknesses, e.g. two-option responses. Below is the task that was used, adapted from ILSQ’s own resources.


Every day at school you have new lessons. There is always a lot of new information to understand and remember. Teachers do their best to make lesson content understandable and memorable, but they can’t satisfy all learners all of the time. So, how can you help yourself to understand and remember? What can you do after a lesson? Below is a list of possible learning strategies. Tick those strategies that you think work well for you.

1. Summarise the lesson in your own words2. Summarise the lesson as a mind map (using your own pictures)
3. Highlight key points using coloured pens4.Try to relate the lesson content to another topic that you have studied
5. Read your notes again to make sure nothing is missing6. Think of extra questions about the content and ask your teacher later
7. Explain the lesson content to another person. See if they understand.8. Study multimedia materials about the same topic, e.g. TV documentary
9. Make linear notes with headings and sub-headings to summarise the lesson content.10. Look at the examples in your course book. Think of extra examples.
11. Review the lesson alone.12. Summarise the lesson as a flow-chart.
13. Discuss the lesson content with classmates.14. Find out how this knowledge is used in the real world.

Differentiated instruction (DI) – a strong rationale, but does it really work?

“We do not teach a group, but thirty separate people.  Because of this, the problem of mixed abilities in the same room seems absolutely natural, and it is the idea of teaching a unitary lesson that seems odd”. (Rinvolucri, 1986)

Rinvolucri’s realization is a common one. In fact, advocates of DI go further, suggesting that it is not just abilities that vary between learners but also degrees of interest and learning styles. All of these variations, it is argued, beg a considered and positive response from the teaching profession. The movement towards catering for all learners also gains support from the fact that in many countries equal access to educational opportunities is enshrined in law.

DI defined

Differentiated instruction is an attempt at a systematic response to learner differences, a framework to help teachers move away from ‘teaching to the middle’. Tailoring lessons for the middle band of students in a class results in some students being over challenged, some under challenged, some unable to gain access to key concepts, and many demotivated. By contrast, with differentiated instruction the aim is to arrange lessons so that all students progress towards desired learning outcomes but reach them in ways that are personally suitable. Lecturers and teachers try to make it possible for all learners to acquire course content, make sense of ideas, and develop learning products that are compatible with their learning profiles.

Historical development of DI

Differentiated instruction is by no means a new phenomenon. Teachers have always practised some degree of differentiation simply by noticing which students require more or less challenge and by asking them different questions. But as a systematic response with a ‘package’ of strategies it is fairly recent. It has been around since the 1980s when it was introduced for the sake of gifted students, and it has received fresh impetus with the move to include students with disabilities into general education classrooms. The cultural make-up of classrooms has also become very diverse with the presence of immigrants and international students. In the United States’ public school system for instance, differentiated instruction has been applied at all levels for students of all abilities. Moreover, it is now an accepted part of pre-service training for teachers in many parts of the world, especially North America, Europe and Australasia.

Supporters of DI

Differentiated instruction has a number of proponents. Key writers on the subject are Susan Winnebrenner (1992, 1996) and Carol Ann Tomlinson (2000). The former writes about particular types of learners, e.g. those with learning difficulties, whereas the latter provides a particularly clear overview. Tomlinson’s book – How to differentiate instruction in mixed-ability classrooms – is available from the ASCD (Association for Supervision and Curriculum Development) in the USA.

Evidence for the value of DI

Tomlinson claims support for her version of differentiated instruction by drawing conclusions from research into teaching and learning:

  1. Learners must make sense of what teachers seek to impart, and this process is influenced by prior knowledge, interests, beliefs, learning styles, and attitudes about self and the place of learning. (National Research Council, 1990)
  2. Learning takes place effectively where knowledge is well-organised, students are actively engaged in the learning process, a variety of testing instruments are employed, and students feel secure and have a sense of belonging to their learning environment. (National Research Council, 1990)
  3. The degree of challenge must be just enough to push learners slightly beyond their independence level. (Vygotsky, 1962)
  4. Motivation to learn increases when students are interested in what they are trying to learn. (Piaget, 1978)
  5. People learn in different ways influenced by factors such as brain architecture, culture and gender. (Delpit, 1995; Gardner, 1983; Sternberg, 1985)

The implications, suggests Tomlinson, are that teachers need to provide learning experiences that encourage students to work in their preferred fashion, are motivating, and challenge them appropriately. Additional support for differentiated instruction comes from classroom examples and testimonials from satisfied students and convinced instructors. However, empirical validation of the full model of differentiated instruction is rather lacking. It is an area that warrants future research.

Introducing DI to Schools: A Hong Kong Case Study

I assisted with action research conducted by teaching staff at Hong Kong secondary schools from 2007-1012. The school leaders were intrigued by DI because the approach appeared to be consistent with their institutions’ mission statements such as “[School name] educators should try to handle each one in the way she is made.” Following a series of training workshops to introduce the approach, teachers were given freedom to experiment in their classrooms for one academic year after which principals and vice-principals observed lessons.

The DI strategies that teachers found more immediately useable were as follows: varied questioning, tiered activities, concept-based teaching and minilessons. It was observed that diagnostic pre-assessments were employed insufficiently at first, but when they were introduced, the following strategies became more workable: curriculum compacting and flexible grouping. As peer feedback became common practice in the school, other strategies became practical, namely peer mentoring and jigsaw activities.

Question for teachers

In your experience of using DI, has it really had an impact on learning and grades?
