Differentiation means tailoring instruction to meet individual needs. Whether teachers differentiate content, process, products, or the learning environment, the use of ongoing assessment and flexible grouping makes this a successful approach to instruction. Differentiated teaching occurs when a teacher plans a lesson that adjusts either the content being discussed, the process used to learn, or the product expected from students to ensure that learners at different starting points can receive the instruction they need to grow and succeed. Some of the differentiation strategies are differentiated through teams, reflection and goal setting, mini-lessons, centers, and resources, voice, and choice in Products differentiate through formative assessments, balance teamwork and individual work, and many more. Now you would be thinking what are the types of differentiation? It is of four types: content, process, product, and learning environment. The three main characteristics are interest, readiness, and learning profile. It can be done in a class in several ways like grouping, varying amounts of time, or changing the task.
If you are thinking about how grouping needs to be done? It is simple: students can be grouped by ability level, interests, or intermingled levels of understanding. If you are thinking of applying this teaching technique in your class go for it!
