Effective instructional differentiation includes the following:

A / Know your students
Educational differentiation begins with a deep knowledge of your students, either as individuals or as a group of learners. It is crucial to do pre-tests to determine students' needs, interests, and ways of learning. Thus, the cultural and linguistic backgrounds of the students.

B / Understanding the study program
The curriculum defines the goals and the skills to be achieved. It also serves as a reference document for further work and learning activities. To develop a curriculum according to differentiated pedagogy, the teacher must help each student to learn at their own pace. In addition, activities and assessments must be useful, fair, and sometimes varied to address different students. Effective educational differentiation supports and reinforces this quality curriculum; it does not replace it. The first step is to fully understand the curriculum you are working with. After that, you can begin to identify ways to help all students achieve learning outcomes by asking yourself questions such as these:

• What are the big ideas contained in this curriculum?

• What are the implications of these learning outcomes for student learning and development?

• What skills and processes are essential to achieving these learning outcomes?

• What are the logical teaching sequences necessary to achieve these results? When will students need help?

• How will these results relate to the different experiences and backgrounds of the students?

• How can I help each student develop their own understanding and skill plan related to these results?

C / Offer different learning paths
Differentiation is based on the use of various teaching methods that help students learn and exercise their knowledge in different ways. For example, the teacher deals with different levels of ability by developing an openness, offering choices, as well as establishing the ability to provide simple or complex answers in activities. In this way, not only does it create opportunities for students to exercise their knowledge in different ways, but it also ensures that students with different levels of receptivity and ability can respond. Offering a greater variety of stimulating, interesting, and curriculum-related activities allows for a better chance of reaching a greater number of students.
Students should also have the opportunity to work in a variety of settings, including individually, with a partner or in small groups, in larger groups and with the whole class.

However, the teacher must not think that he individualizes the teaching or abolishes all the moments of collective work. Rather, it is a matter of offering students different means allowing them to pursue their own path. The practice of differentiation in instruction requires organizing the classroom in a way that allows each learner to learn under conditions that suit them best. It is also putting in place in the classroom systems and means that facilitate the achievement of the objectives of the study programs.
