Differentiation refers to a wide variety of teaching techniques and lesson adaptations that educators use to instruct a diverse group of students, with diverse learning needs, in the same course, classroom, or learning environment. Differentiation is commonly used in “heterogeneous grouping”—an educational strategy in which students of different abilities, learning needs, and levels of academic achievement are grouped together.
In heterogeneously grouped classrooms, for example, teachers vary instructional strategies and use more flexibly designed lessons to engage student interests and address distinct learning needs—all of which may vary from student to student. The basic idea is that the primary educational objectives—making sure all students master essential knowledge, concepts, and skills—remain the same for every student, but teachers may use different instructional methods to help students meet those expectations.
Teachers who employ differentiated instructional strategies will usually adjust the elements of a lesson from one group of students to another, so that those who may need more time or a different teaching approach to grasp a concept get the specialized assistance they need, while those students who have already mastered a concept can be assigned a different learning activity or move on to a new concept or lesson.
In more diverse classrooms, teachers will tailor lessons to address the unique needs of special-education students, high-achieving students, and English-language learners, for example. Teachers also use strategies such as formative assessment—periodic, in-process evaluations of what students are learning or not learning—to determine the best instructional approaches or modifications needed for each student.
Also called “differentiated instruction,” differentiation typically entails modifications to:
- practice (how teachers deliver instruction to students),
- process (how the lesson is designed for students),
- products (the kinds of work products students will be asked to complete),
- content (the specific readings, research, or materials, students will study),
- assessment (how teachers measure what students have learned), and
- grouping (how students are arranged in the classroom or paired up with other students).
Differentiation techniques may also be based on specific student attributes, including interest (what subjects inspire students to learn), readiness (what students have learned and still need to learn), or learning style (the ways in which students tend to learn the material best).
Differentiation vs. Scaffolding
As a general instructional strategy, differentiation shares may similarities with scaffolding, which refers to a variety of instructional techniques used to move students progressively toward stronger understanding and, ultimately, greater independence in the learning process.
Because differentiation and scaffolding techniques are used to achieve similar instructional goals—i.e., moving student learning and understanding from where it is to where it needs to be—the two approaches may be blended together in some classrooms to the point of being indistinguishable. That said, the two approaches are distinct in several ways.
When teachers differentiate instruction, they might give some students an entirely different reading (to better match their reading level and ability), give the entire class the option to choose from among several texts (so each student can pick the one that interests them most), or give the class several options for completing a related assignment (for example, the students might be allowed to write a traditional essay, draw an illustrated essay in comic-style form, create a slideshow “essay” with text and images, or deliver an oral presentation).
Alternatively, when teachers scaffold instruction, they typically break up a learning experience, concept, or skill into discrete parts, and then give students the assistance they need to learn each part. For example, teachers may give students an excerpt of a longer text to read, engage them in a discussion of the excerpt to improve their understanding of its purpose, and teach them the vocabulary they need to comprehend the text before assigning them the full reading.
The following comparison chart will help illustrate the differentiation concept and its major component strategies:
Myths and Misconceptions about Differentiated Instruction and Universal Design for Learning
Differentiated instruction is just one component of UDL. Tomlinson (2001), declares that differentiated instruction is the intentional application of specific lesson planning and multiple learning approaches to support all learners.
The key difference between differentiated instruction and UDL is that differentiation is a strategy that supports instructors in addressing each student’s individual level of readiness, interest, and learning profiles (Nelson, 2014).
UDL in comparison is an overarching educational framework that addresses the learning environment as a whole. This includes, both the physical learning environment as well as the lessons, units, and/or curriculum. When the whole environment is addressed first, it removes physical, mental and psychological barriers so all students have full access in the classroom, regardless of their needs and abilities.
Differentiation plays into ongoing debates about equity and “academic tracking” in public schools. One major criticism of the approach is related to the relative complexities and difficulties entailed in teaching diverse types of students in a single classroom or educational setting.
Since effective differentiation requires more sophisticated and highly specialized instructional methods, teachers typically need adequate training, mentoring, and professional development to ensure they are using differentiated instructional techniques appropriately and effectively.
Some teachers also argue that the practical realities of using differentiation—especially in larger classes comprising students with a wide range of skill levels, academic preparation, and learning needs—can be prohibitively difficult or even infeasible.
Yet other educators argue that this criticism stems, at least in part, from a fundamental misunderstanding of the strategy. In her book How to Differentiate Instruction in Mixed-Ability Classrooms, the educator and writer Carol Ann Tomlinson, who is considered an authority on differentiation, points out a potential source of confusion:
“Differentiated instruction is not the ‘Individualized Instruction’ of the 1970s.”
In other words, differentiation is the practice of varying instructional techniques in a classroom to effectively teach as many students as possible, but it does not entail the creation of distinct courses of study for every student (i.e., individualized instruction).
The conflation of “differentiated instruction” and “individualized instruction” has likely contributed to ongoing confusion and debates about differentiation, particularly given that the terms are widely and frequently used interchangeably.

Differentiated Instruction and Implications for UDL Implementation
To differentiate instruction is to recognize students’ varying background knowledge, readiness, language, preferences in learning and interests; and to react responsively. As Tomlinson notes in her recent book Differentiated Classroom: Responding to the Needs of All Learners (2014), teachers in a differentiated classroom begin with their current curriculum and engaging instruction. Then they ask, what will it take to alter or modify the curriculum and instruction so that so that each learner comes away with knowledge, understanding, and skills necessary to take on the next important phase of learning. Differentiated instruction is a process of teaching and learning for students of differing abilities in the same class. Teachers, based on characteristics of their learners’ readiness, interest, learning profile, may adapt or manipulate various elements of the curriculum (content, process, product, affect/environment). These are illustrated in Table 1 below which presents the general principles of differentiation by showing the key elements of the concept and relationships among those elements.
While Tomlinson and most recognize there is no magic or recipe for making a classroom differentiated, they have identified guiding principles, considered the “Pillars that Support Effective Differentiation”: Philosophy, Principles, and Practices. The premise of each is as follows:
The Philosophy of differentiation is based on the following tenets:
- (1) recognizing diversity is normal and valuable,
- (2) understanding every student has the capacity to learn,
- (3) taking responsibility to guide and structure student success,
- (4) championing every student entering the learning environment and assuring equity of access
The Principles identified that shape differentiation include
- (1) creating an environment conducive to learning
- (2) identifying a quality foundational curriculum
- (3) informing teaching and learning with assessments
- (4) designing instruction based on assessments collected
- (5) creating and maintaining a flexible classroom
Teacher Practices are also essential to differentiation, highlighted as
- (1) proactive planning to address student profiles
- (2) modifying instructional approaches to meet student needs
- (3) teaching up (students should be working just above their individual comfort levels)
- (4) assigning respectful tasks responsive to student needs—challenging, engaging, purposeful
- (5) applying flexible grouping strategies (e.g., stations, interest groups, orbital studies)
- Several elements and materials are used to support instructional content. These include acts, concepts, generalizations or principles, attitudes, and skills. The variation seen in a differentiated classroom is most frequently in the manner in which students gain access to important learning. Access to content is seen as key.
- Align tasks and objectives to learning goals. Designers of differentiated instruction view the alignment of tasks with instructional goals and objectives as essential. Goals are most frequently assessed by many state-level, high-stakes tests and frequently administered standardized measures. Objectives are frequently written in incremental steps resulting in a continuum of skills-building tasks. An objectives-driven menu makes it easier to find the next instructional step for learners entering at varying levels.
- Instruction is concept-focused and principle-driven. Instructional concepts should be broad-based, not focused on minute details or unlimited facts. Teachers must focus on the concepts, principles, and skills that students should learn. The content of instruction should address the same concepts with all students, but the degree of complexity should be adjusted to suit diverse learners.
- Clarify key concepts and generalizations. Ensure that all learners gain powerful understandings that can serve as the foundation for future learning. Teachers are encouraged to identify essential concepts and instructional foci to ensure that all learners comprehend.
- Flexible grouping is consistently used. Strategies for flexible grouping are essential. Learners are expected to interact and work together as they develop knowledge of new content. Teachers may conduct whole-class introductory discussions of content big ideas followed by small group or paired work. Student groups may be coached from within or by the teacher to support completion of assigned tasks. Grouping of students is not fixed. As one of the foundations of differentiated instruction, grouping and regrouping must be a dynamic process, changing with the content, project, and on-going evaluations.
- Classroom management benefits students and teachers. To effectively operate a classroom using differentiated instruction, teachers must carefully select organization and instructional delivery strategies. In her text, How to Differentiate Instruction in Mixed-Ability Classrooms (2001), Carol Tomlinson identifies 17 key strategies for teachers to successfully meet the challenge of designing and managing differentiated instruction.
- Emphasize critical and creative thinking as a goal in lesson design. The tasks, activities, and procedures for students should require that they understand and apply meaning. Instruction may require supports, additional motivation; and varied tasks, materials, or equipment for different students in the classroom.
- Initial and on-going assessment of student readiness and growth are essential. Meaningful pre-assessment naturally leads to functional and successful differentiation. Incorporating pre- and on-going assessment informs teachers so that they can better provide a menu of approaches, choices, and scaffolds for the varying needs, interests, and abilities that exist in classrooms of diverse students. Assessments may be formal or informal, including interviews, surveys, performance assessments, and more formal evaluation procedures.
- Use assessment as a teaching tool to extend rather than merely measure instruction. Assessment should occur before, during, and following the instructional episode; and it should be used to help pose questions regarding student needs and optimal learning.
- Students are active and responsible explorers. Teachers respect that each task put before the learner will be interesting, engaging, and accessible to essential understanding and skills. Each child should feel challenged most of the time.
- Vary expectations and requirements for student responses. Items to which students respond may be differentiated so that different students are able to demonstrate or express their knowledge and understanding in a variety of ways. A well-designed student product allows varied means of expression and alternative procedures and offers varying degrees of difficulty, types of evaluation, and scoring.
- Developing a learning environment. Establish classroom conditions that set the tone and expectations for learning. Provide tasks that are challenging, interesting, and worthwhile to students.
- Engaging all learners is essential. Teachers are encouraged to strive for the development of lessons that are engaging and motivating for a diverse class of students. Vary tasks within instruction as well as across students. In other words, an entire session for students should not consist of all lecture, discussion, practice, or any single structure or activity.
- Provide a balance between teacher-assigned and student-selected tasks. A balanced working structure is optimal in a differentiated classroom. Based on pre-assessment information, the balance will vary from class-to-class as well as lesson-to-lesson. Teachers should ensure that students have choices in their learning.
The following instructional approach to teaching mathematics patterns has several UDL features (see Table 2). Through the use of clearly stated goals and the implementation of flexible working groups with varying levels of challenge, this lesson helps to break down instructional barriers. We have identified additional ways to reduce barriers in this lesson even further by employing the principles of UDL teaching methods and differentiated instruction. We provide recommendations of employing teaching methods of UDL to support this lesson in Table 3. Please note that we are not making generalized recommendations for making this lesson more UDL, but instead are focusing on ways that differentiated instruction, specifically, can help achieve this goal.
Table 2. UDL Elements in a Differentiated Instruction Mathematics Lesson
|UDL Guideline/Checkpoint||Differentiated Instruction Features|
|Provide multiple examples.||The teacher provides multiple examples throughout the lesson with multiple models, practice activities, and additional math problems.|
|Highlight critical features.||The teacher highlights critical features of the mathematics by stopping and calculating, checking in with students, and modeling behavior.|
|Provide multiple media and formats.||The teacher supports understanding by identifying patterns not only in text but also in the environment of the classroom, school, etc.|
|Support background context.||Teachers analyze or pre-test students for key pre-skills and background knowledge.|
|Provide ongoing, relevant feedback.||In cooperative groups, students may receive feedback from the teacher and from peers.|
|Offer choices of content and tools.||Students are assigned to one of three groups tiered by difficulty; all students are working on the same task but with varying supports.|
|Offer adjustable levels of challenge.||Varied supports in the working groups alter the level of independence and difficulty in solving the task.|
