The SciTrain U Accessible Classroom Course provides techniques that will assist you in creating universally accessible classrooms and laboratories for students with diverse abilities and learning skills. The philosophy behind "accessibility" and the related concept of "universal design" originated with the idea of adapting the environment to accommodate the user. Within the context of education, it has evolved to encompass the idea that accommodations for students with disabilities can benefit non-disabled students as well. We will provide numerous examples of how this works in the real world. This course provides quick access to practical information on ways of teaching that will increase your students’ knowledge retention, in-class participation, and understanding of class material the first time they encounter it. SciTrain U focuses on classrooms and labs for science, mathematics, engineering, and computer science, but many of these techniques and technologies are applicable elsewhere. Registration and cost are free.
