Two graduate teaching assistants (TAs)--one taught language arts methods and the other taught social studies methods--who were office mates at a large university in Florida formulated a plan to create one end-of-course project that would both satisfy requirements and combine the social studies and language arts. That way, students could see that both content areas could work together, and social studies might have a larger portion of the curriculum than otherwise planned. The two TAs put the students in groups of two or three and assigned them one of the 10 social studies content standards developed by the National Council for the Social Studies. Under this umbrella, the groups were to create a thematic unit related to Florida that combined the state's language arts and social studies standards (Sunshine State Standards) in at least five lesson plans. Units were graded on a scale of 1-100, with opportunities to revise before the final product was presented to the class and turned in. Specific components that were required include lesson plans, writing in multiple genres, at least five literature-related sources, a written proposal and justification, and ESOL/ESE modifications. Additional attributes that were noted were quality, clarity, and structure of the lesson plans, the value of the material and activities included, appropriate evaluation of learning, and efficient use of class time. Most groups were able to develop an interdisciplinary unit that equally emphasized both content areas, and held true to the state of Florida as a part of the theme. Contains 6 references.
