According to the National Center on Universal Design for Learning, Universal Design for Learning (UDL) is a set of principles for curriculum development that give all individuals equal opportunities to learn.
UDL provides a blueprint for creating instructional goals, methods, materials, and assessments that work for everyone–not a single, one-size-fits-all solution but rather flexible approaches that can be customized and adjusted for individual needs.
It is important when designing your curriculum that you meet the needs of all learners, whether you are using technology or not. However, technology is a power tool that has enabled UDL to be a lot easier. You should note that these technologies should not be the only way to implement UDL principles into your curricula.
Effective uses of technologies can play an important role within the instructional outcome. It is important that you successfully use these technologies because some technology can have the same accessibility issues as using a method without technology.
In conclusion, technology is not the same as UDL, but it does play a valuable role in assisting with curriculum design and its implementation and conceptualization.
