Of all the topics in the 7th grade health curriculum, the nutrition unit provides students with skills that can be immediately applied to their lifestyle. In addition to learning about traditional nutrition topics like the USDA’s “My Pyramid” (updated food guide pyramid), the five food groups, and the six main nutrients, students also learn how to make healthy choices, analyze nutrition labels, calculate daily caloric intake, recognize appropriate serving size, and menu planning skills.
I am planning to create a “nutrition” wiki for my students. As this is my first attempt at creating and using a wiki with my classes, I do not want to be overwhelmed by managing a large number of students who are also first time wiki users. With this in mind, the wiki will be created for one of my six classes (40 students). Initially, I will limit the scope of this wiki to one topic of the nutrition unit.
The Basics:
Most 7th grade students have no idea of how many calories they consume or what an appropriate serving size looks like. A balanced diet, what is that? In order to gain a better understanding of their eating habits, students will be required to document everything they eat for one week using a food diary. This will be done at the beginning of the nutrition unit and again at the end of the semester. Prior to any discussion about eating a balanced diet or introducing the guidelines of “My Pyramid”, students will complete the food diary worksheet. They will record all meals, snacks, and beverages they consume. To address serving size, students will be provided a guide that teaches them to use their hand as a measurement tool (ie- your fist is equivalent to one cup, or your thumb is equivalent to a tablespoon). Once they have recorded this data, students will post the information to the class wiki. After the students post their food diary, the topics of eating a balanced diet and the guidelines of “My Pyramid” will be discussed in class. Once this foundation of knowledge is established, they will be required to review the food diaries of three classmates.
**The specific lesson plan details for sub coverage would need to be determined at that time. Due to our school schedule and the many transitions of my classes {health (35 minutes) and PE (60 minutes) are combined in a block schedule format}, this learning opportunity will need to take place over several days.
Days 1 & 2: Introduce the challenge and cover the wiki basics, ground rules, and etiquette. The mobile computer lab will be used for completing this assignment.
Day 3: Hand out and explain/demonstrate how to use the food diary worksheet. Students will practice completing the food diary with a sample menu for one day.
Day 4: Hand out and explain how to use the serving size guide. Many examples will need to be provided for students to practice using their hands as a measurement tool to determine appropriate serving size.
Day 5: Begin using the food diary to track all meals, snacks, and beverages consumed for one week.
Day 6 & 7: Students transfer food diary results to their class wiki page.
Day 8: Peer review of food diaries using these prompts:
- Has this student completed his/her food diary for seven days?
- Did they include all of the required information (food/beverage description and serving size)?
- How does this diet meet the requirements of “My Pyramid”?
- In your opinion, has this student considered appropriate serving size?
- What recommendations can you offer to help your classmate eat a more balanced diet?
Potential risks:
- Student problems using the wiki- The teacher would need to dedicate ample time and resources when introducing the wiki and how to properly manage/navigate the site. Ground rules will also need to be established.
- Vandalism of the site might be a problem. I am starting with a good group of students and limiting the participants to one class.
- Require a parent signature on the food diary to confirm the authenticity of the results. Once this has been received, the student can post the results to the wiki.
