<p>The use of open education is growing and has become a global movement. Across much of North America, most post-secondary institutions are in the process of integrating the use of open education resources into teaching and learning activities.

Across much of North America, most post-secondary institutions are in the process of integrating the use of open education resources into their teaching and learning activities. The number of OER repositories from which instructors can draw resources continues to grow each year. The number of resources continues to grow along with the number of different tools used to develop these resources.  There are a number of commercial and open source digital technologies available for the creation of open resources. This resource is intended to provide the OER community with a summary of some currently available tools for creating open content. OER creators need to know the range of tools that can be used in the creation process. This guide is designed to provide a starting point for instructors and faculty at post-secondary institutions. Prospective creators of OER can use the guide to pick the most appropriate tool for their specific context and level of technical expertise.
