The Dilemmas of Differentiation

Differentiation is necessary, but it also brings tensions

Most educators agree that differentiation is essential for good teaching. But anyone who actually tries to differentiate quickly discovers that it comes with difficult choices. What do you do when the gaps between students actually grow wider as a result of differentiating? How much extra attention can you give to students who need more support before it starts to come at the cost of everyone else? And is grouping students by ability level helpful or stigmatizing?

Researchers at Fontys University of Applied Sciences identified six of these tensions as differentiation dilemmas (Fontys Lectoraat Waarden van Diversiteit, n.d.). This article examines those dilemmas and places them in scientific context.

1. The Learning Outcomes Dilemma: Equal Goals or Individual Pace?

The first dilemma goes to the heart of differentiation: what learning goals do you set? If you differentiate so that every student pursues their own goals at their own pace, the gaps between students will inevitably grow. If you focus instead on getting all students to the same goal, you move on only when most students have mastered the material. But then students who already have it are standing still (Fontys Lectoraat Waarden van Diversiteit, n.d.).

This dilemma touches on a fundamental debate in educational theory. Tomlinson (2001) emphasizes that differentiation should respond to individual learning needs, but also acknowledges that teachers struggle with the tension between common standards and individual growth trajectories. In practice, this means schools must constantly weigh: do we invest in convergence (bringing everyone to the same level) or divergence (helping everyone grow as far as possible)?

2. The Support Dilemma: Equal Attention or Equal Opportunity?

Teachers have limited time and energy. Students who have not yet mastered the material typically require the most instruction and guidance. Add to that the fact that some students receive little support at home. Parents with less formal education are often less able to help with homework (Fontys Lectoraat Waarden van Diversiteit, n.d.). The dilemma is clear: do you give all students equal amounts of attention, or do you give students with less home support even more?

This connects to the distinction between equality and equity. Research on educational inequality consistently shows that students' home circumstances are strongly associated with their academic performance (OECD, 2018). From an equity perspective, an unequal distribution of teacher attention can be entirely justified because it aims to compensate for unequal starting points. At the same time, researchers caution that this must not come at the expense of the development of students who are capable of working more independently (Tomlinson & McTighe, 2006).

3. The Grouping Dilemma: Good for Confidence or Stigmatizing?

In many schools, students are placed into homogeneous ability groups for subjects like math and reading. The dilemma concerns the possible effects of this grouping on students' self-confidence (Fontys Lectoraat Waarden van Diversiteit, n.d.).

On one side: ability groups can actually boost self-confidence. Students with lower performance are not constantly confronted with classmates who are further ahead. They receive instruction tailored to where they are, alongside others in a similar situation.

On the other side: ability groups can be stigmatizing. Students in the lower groups typically know exactly where they stand, and this can lead to a negative self-image, not only in their own eyes but in the eyes of others. Oakes (2005) showed that ability-based grouping can reinforce existing social inequalities.

The difference lies in implementation. Fixed, labeled ability groups function differently from flexible, rotating grouping arrangements. Pozas et al. (2021) found that differentiation can have positive effects on students' self-concept, but only when it is structured in a non-stigmatizing way (Tomlinson, 2001).

4. The Gifted Learners Dilemma: In the Classroom or in a Pull-Out Program?

Gifted students often need enrichment and acceleration that the standard curriculum does not provide. The dilemma: should the enriched curriculum be delivered within the regular classroom as much as possible, so that students at different levels can learn from each other? Or do gifted students benefit more from a separate setting, such as a pull-out program, where they work with peers at a comparable level (Fontys Lectoraat Waarden van Diversiteit, n.d.)?

There is no single clear answer. Gifted students benefit from working with cognitively similar peers, but social integration with age-mates is also important for their social-emotional development (Tomlinson, 2001). Technology increasingly makes it possible to offer a wider range of challenges within the regular classroom, without pulling students out.

5. The Inclusion Dilemma: Special Education or General Education?

The inclusion dilemma concerns how strongly you support inclusive education. In this approach, students with disabilities or learning differences attend general education schools, with specialized support brought into the school (Fontys Lectoraat Waarden van Diversiteit, n.d.).

On one side: for some students, their needs are significant enough that a specialized school offers a better fit. The general education classroom cannot always provide what they need for meaningful growth. On the other side: school should be accessible to all students. Every child has the right to attend a general education school, and education has a responsibility to provide a suitable place.

This is fundamentally a question of values: does the right to inclusion outweigh access to specialized care? Pozas et al. (2021) found that differentiation is used more often in inclusive classrooms than in standard classrooms, but that its effectiveness depends heavily on available resources, class size, and the quality of teacher training. Langelaan et al. (2024) emphasize that successful differentiation programs must be sustained, comprehensive, and well supported.

6. The Focus Dilemma: Academic Achievement or Whole-Child Development?

The final dilemma concerns how teachers distribute their attention across the different goals of education: academic development, personal growth, and civic development (Fontys Lectoraat Waarden van Diversiteit, n.d.). Teachers know this tension well: when a conflict erupts on the playground after recess, the question arises whether the planned lesson is really the right response to what is happening in the classroom.

On one side: students develop their identities together at school and learn to participate in society. Opportunities for personal and civic growth deserve space, even if that means stepping back from academic objectives. On the other side: school exists to help students achieve the highest possible academic outcomes, and lessons demand focus on those goals.

This dilemma reflects a broader discussion about what education ultimately aims to do. Pozas et al. (2021) showed that differentiation can improve not only academic but also social-emotional outcomes, which suggests that cognitive and broader developmental goals can reinforce each other when differentiation is done well.

Conclusion: Dilemmas as Compass

The existence of these dilemmas is not a reason to avoid differentiation. Quite the opposite. These tensions are precisely what push teachers to make conscious, thoughtful choices. As Tomlinson (2001) puts it: differentiation is not a recipe, but a way of thinking about teaching that puts the individual learner at the center.

For schools and teams, these dilemmas can serve as a starting point for professional conversation. By reflecting together on the underlying values and assumptions, space opens up for a shared vision of how to work with diversity. And it is that shared vision that forms the foundation for effective differentiation in practice.

Differentiation takes time, especially for homework, where students work independently without direct support from the teacher. HomeWorkLevels makes it easier to match assignments to each student's level, so teachers can focus on what they do best: teaching.
