This unit focuses on understanding through application. All OPEN NH online courses utilize a course project that asks you to apply the content you are learning to a project that you can use directly in your classroom or your school. As discussion adds depth of knowledge, so application adds richness of understanding. Quality professional development in the 21^st Century should be sustained over time and job embedded. Online courses provide you with sustained opportunities for learning content. The projects they involve allow you to practice your learning in the classroom. In this tutorial, you will explore how powerful classroom projects can be, and in doing so appreciate the value of doing your own applied projects.
