Presession: Waste in the Cafeteria Survey

  1. Assign students to conduct a personal survey of the amount of food they throw away each day at lunch using the Cafeteria Waste Activity Sheet.

  2. After five days of data collection, divide students into groups of three to five. Have them compile and analyze the information they have collected by determining the overall percentage of food wasted over the last five days.

  3. Have each group of students synthesize their findings into a pie chart that can be displayed. Have the class draw conclusions about the findings as they examine the charts. Collect students’ activity sheets for assessment.

Session 1: PowerPoint Presentation

  1. Teach persuasion basics using The Art of Persuasive Writing PowerPoint presentation, having students take notes. Use the presentation notes included at the bottom of some of the slides to guide your discussion. Stop frequently to allow students to share their own examples of persuasive speech. Presentation highlights include types of persuasive speech, elements of the persuasive essay, and persuasive vocabulary like logos, pathos, ethos, and counterarguments.

Session 2: Analysis/Deconstruction of the Persuasive Argument in Video Format

  1. Watch TED Talk: Marcel Dicke: Why Not Eat Insects? as a class.

  2. As they watch the video, have students take notes using the Why Not Eat Insects? Notes Organizer.

  3. After watching the video, discuss the presenter’s purpose and intended audience with students.

  4. Have students use their notes to fill in the ReadWriteThink Persuasion Map, identifying the thesis and major supporting arguments. Collect their notes organizers for assessment.

Sessions 3–4: Research (computer days)

  1. Set a purpose for reading the following articles: Food Facts: Your Scraps Add Up, Food Waste Basics, and the Waste Not, Want Not blog. Review what students know about food waste.

  2. Review the four metacognitive strategies in the Metacognitive Strategies Chart: connect, question, infer, and evaluate. Remind students to preview the articles by reading the titles, examining the graphics, and reading the captions.

  3. Have students explore the online articles for answers to the food waste problem. Briefly model the process of collecting information from the online articles.

  4. Have students record their findings on the Research Guide.

Session 5: Developing Thesis and Arguments (optional computer day)

  1. Briefly model the process of developing a single, focused thesis and arguments from the Research Guide. Some students may want to tackle all of the issues discovered in their research, so you should provide the necessary scaffolding as students work to narrow their focus. (Please note that the focus of Waste Not, Want Not is reducing food waste at home; however, students should be free to choose any food waste topic from their research when writing their own blogs.)

  2. Have students develop a thesis and arguments for their own blog post, offering persuasive solutions to the waste problem. Students should refer to facts from the Research Guide to craft their arguments.

  3. Have students consider the appropriate tone for their electronic audience. Since students are addressing their own academic community about a social issue, the tone should be thoughtful and insightful. Caution students to avoid informal or flippant remarks.

  4. Students may use the ReadWriteThink Persuasion Map to plan their blog. If a computer lab is not available, students may use a hard-copy persuasion map instead (click on “Print Blank Map” on the interactive page).

  5. Have students print out their work at the end of the session. Collect both the Research Guide and the Persuasion Map for assessment.

Session 6: Writing the Rough Draft

  1. Hand out and explore the Persuasive Blog Rubric. Explain to students that assessment for the remaining sessions is ongoing, based on the rubric, and culminates in each student publishing a blog post and two responses.

  2. Model applying the Persuasive Blog Rubric to the mentor text, Waste Not, Want Not. Ask students to identify the thesis statement and supporting arguments. Extend the discussion by having students evaluate the quality of each blog post argument and whether or not the author has successfully tailored those arguments to an electronic audience.

  3. Have students apply what they have learned by writing the initial draft of their blog. Students should write about a topic from their research that interested them. For example, they could write about the costs of meat production, how restaurants can reduce waste, or how food waste contributes to rising methane levels.

Session 7: Revising and Publishing Persuasive Blogs (computer day)

  1. Have students evaluate their blog post drafts using the Persuasive Blog Rubric. Students may work in pairs or as individuals. Have students check to make sure each blog post includes a thesis statement, supporting arguments, and a well-developed conclusion; has an appropriate academic tone; and is free of convention errors.

  2. Have students revise based on self-evaluation and, if working in pairs, peer feedback.

  3. Have students publish blog posts.

Sessions 8–9: Response and Reflection (computer day)

  1. Briefly review the Persuasive Blog Rubric for the response criteria.

  2. Display the Metacognitive Strategies Chart on the board, and discuss how the strategies lead to insightful responses that further the blogging conversations.

  3. Examine the blog post responses in Waste Not, Want Not. As a class, rate each response according to the criteria outlined in the Persuasive Blog Rubric, identifying the responses that are insightful and further the conversation. Brainstorm other possible responses.

  4. Have students read at least two other student blogs and respond to each.

  5. Circulate around the room to check for student understanding and response quality. Scaffold and support students by offering specific feedback. Look for evidence that students are crafting well-thought-out responses by making connections, questioning, inferring, and/or evaluating.

  6. Review each student’s blog posts and responses, and evaluate them according to the Persuasive Blog Rubric.
