Brokers of Expertise is a CDE-sponsored resource and professional network for teachers and administrators throughout the state. It's kind of like LinkedIn, but specifically for California educators. When you sign up (at myboe.org), you will be automatically connected to groups for your school and your district. There are also other groups that you could join, either for your content area, or for special education, or for educational technology, or any other specific interest. When you join a group, you have access to all the resources (links, files, lesson plans) submitted to that group from teachers all around the state. If you don't find a particular group, you can create your own group and invite others.
This kind of online community is a great way to build your professional learning network, especially if you are the only teacher for a class at your site (or in the district). You can get help and suggestions and resources from teachers across the state. Try it out, at myboe.org.
