I have found that the following sources have been very useful in the integration of active learning, collaboration and problem based instruction in my principles classes:
Foundation for Teaching Economics http://www.fte.org
While this curriculum has been designed for the high school level, many of the activities/lessons are easily adapted to the principles class. For example, the Economic Forces in American History is an outstanding example/array of interdisciplinary approach to instruction in economic history.
Another excellent interdisciplinary set of activities can be found in the links for Economics of Disasters
This link provides an example of the support/instruction that the FTE provides.
The National Council on Economic Education and the local councils - in my case the Arizona Council on Economic Education.
I suspect most of the economics faculty are familiar with the National Council - like the FTE there are a number of excellent high school resources that are easily adapted to the community college environment -
The key resource at the above site is Virtual Economics = a must resource for your library
Office of Economic Education - University of Arizona
I love this site - as I teach US Economic History this site has super support - resources, book reviews, data, and an encyclopedia.
For example at https://eh.net/databases/ you will be pointed to number of great data sources both within and without EH. As many of you may know, the NBER macro data set is accessible and very useful for student research.
TR Brown Economic Understanding
If you click below you will find examples of resources, professional development, links to other resources. While designed for high school instruction much of the material here is of use to community college faculty.
