Here is a link to a lesson plan which I will be likely to use in the future for English classes. I located it through the ODE Information Management System website link for lesson plans. 
 Lesson Plan: Credibility of Sources - Grade 11
  http://dnet01.ode.state.oh.us/IMS.ItemDetails/LessonDetail.aspx?id=0907f84c80532c74
This lesson plan teaches students what credibility means and how to assess the credibility of information and sources found in various media.  In one activity students view clips of the same news story as covered by two different news stations and compare the information and opinions presented in each. The students are taught to apply standards for evaluating sources using a rubric called Rubric for Discriminating Viewers.
I really like this lesson plan because there is a superabundance of information available through television, the internet and other media and students need to be able to use critical thinking skills to sort through it and determine what is most/least trustworthy.
