Check out national or state educational standards for the grade level you are targeting. Teachers generally are most concerned with their local or state standards, so you might look at those, if you can identify localities that matter to your project. Otherwise, look at national standards. Even if you plan to focus on an informal educational audience, it's still important to align your content with what kids will be learning in school. Do a quick search of what else is out there on your subject. You can do a Web search, look at some educational catalogues, or scan some popular textbooks. Hold a focus group of local educators who meet the profile of your target. Ask them what they commonly cover in your area, or what topics are difficult to teach or lacking in media support. Run some of your content ideas by them and ask them to prioritize them. See if friends in other states can connect you with teachers in their area you can talk to on the phone or via e-mail to gain a wider perspective. But remember to balance your findings with what else you can determine about trends and reform efforts in that subject area, especially if you're hoping to initiate some change in how your subject is handled. Some of these trends are described in the Research & Resources section of this guide. If you are targeting an informal education audience, hold a focus group of after-school providers, librarians, museum educators, and others who work with your target audience. Find out about the basic structure of their programs and what particular issues pertain to the students they work with. For example, many after-school programs have drop-in populations, so it is more difficult for them to do long-term programs. Moreover, their staff may be paraprofessionals who have little formal educational training. Thus, they may require more explicit and structured materials, and greater support on your part.
