There are two general models for how NSDL’s blogosphere may be used to support both STEM education and ongoing Library community development: Discovery Team Expert Voices Blogs and Community Expert Voices Blogs. Each type of blog conversation can include multiple bloggers and numerous participants who comment on blog posts. It is expected, however, that Discovery Team Expert Voices Blogs will have interdisciplinary participation from some combination of subject experts, teachers, librarians and students such as:

Subject expert, teacher, students
Subject expert, librarian, students
Subject expert, teacher, librarian
Professor, students, guest speakers or lecturers (bloggers)
Distance education classes, subject expert
Subject expert, pre-service teachers, teachers, students
Subject expert, pre-service school librarians, students
Subject expert, pre-service school librarians, teachers
Multiple permutations of the above team members
Other team members could be parents, museum educators, informal science representatives, graduate and doctoral student subject experts.

The following scenarios are also related to a blog’s duration–is the conversation ongoing, or will it last for a specific period of time or for a single event? See Life Cycle of an Expert Voices blog here.

Model 1: Discovery Team Expert Voices Blogs

Bloggers who participate in Discovery Team Expert Voices Blogs are creating educational “products” that will become a part of the National Science Digital Library for others to use.
A blog that creates resource lists around a focused topic
Participants share and discuss resources that work
Example: Teaching Measurement at the Middle School Level
A blog that creates a lesson plan around a focused or broad topic
Participants trade ideas and structure resources into a step-by-step lesson plan designed for a specific grade level.
Example:
A blog that promotes an exchange ofideas around a focused or broad topic
In this scenario bloggers trade ideas and insights on educationally relevant topics that my be tied to current events or to broad educational topics.
Example: Presentation of Math on the Web

Model 2: Community Expert Voices Blogs

These types of blogs explore issues of signigicance to various segments of the NSDL network of projects and partners
Blogs that discuss current STEM news and events
These blog exchanges provide additional context for current internal or external news by discussing both online web materials and references as well as resources that may be within the NSDL collection.
Example: NSDL News Topic Center
Blogs that promote educational outreach
These blogs support ongoing educational outreach activities and present new resources that support their development.
Example: Bringing the Field to the Classroom
Administrative and editorial blogs
From highlighting and providing pointers into blogs, to creating ongoing help documentation, these types of blogs help users navigate and make use of the NSDL blogosphere.
Example: Observation Tower
