Judging a Paper Airplane Contest
This activity has been undergone anonymous peer review.
This activity was anonymously reviewed by educators with appropriate statistics background according to the CAUSE review criteria for its pedagogic collection.
This page first made public: Nov 3, 2009
This material was originally developed through CAUSE
as part of its collaboration with the SERC Pedagogic Service.
- Expose students to a real-world problem with real data.
- Expose students to ideas of central tendency and variability.
- Provide students with a conceptual understanding of analysis of variance.
- Engage students in statistical thinking and working as a team.
Context for Use
- Is appropriate for use at any time in an introductory statistics course.
- May be adapted for junior high, high school, and college-level instruction.
- Is most effective when students work in groups of 3-4.
- Lasts 50 - 75 minutes. The reading and individual students responses can take place prior to class and comparison of student reports can take place at a subsequent class or via an online class management system.
Description and Teaching Materials
- Media article: Students individually read the media article to become familiar with the context of the problem. This handout is available here. Paper Airplane Media Article (Microsoft Word 571kB Oct8 09)
- Readiness questions: Students individually answer these questions about the media article to become even more familiar with the context and begin thinking about the problem. This handout is available here. Paper Airplane Readiness Questions (Microsoft Word 25kB Oct8 09)
- Problem statement: In teams of three or four, students are given the problem statement and work on the problem in a group for 30 - 45 minutes. This time range depends on the amount of self-reflection and revision you want the students to do. The handout is available here. Paper Airplane Problem Statement (Microsoft Word 60kB Oct8 09)
Note: There are two additional files that may also be provided to students: Scatterplots that graphically represent the data Paper Airplane Scatterplots (Microsoft Word 691kB Oct8 09); or the actual data as a Fathom file if the instructor wants students to analyze the data themselves Paper Airplane Fathom Data ( 8kB Aug26 09).
- Process of sharing solutions: Each team writes their solution in a letter or memo to the client. Then, each team presents their solution to the class. Whole class discussion is integrated with these presentations to discuss the different solutions, the statistics involved, and the effectiveness of the different solutions in meeting the needs of the client.
The following supplies and materials are recommended for this activity.
- Computers with word-processing programs to write up their reports.
- Optional: Computers with programs such as Fathom
- Optional: Calculators
- Optional: Materials for students to create posters to share their solutions.
Teaching Notes and Tips
- It is useful to prepare the students to work on this activity by having them make and fly paper airplanes. One recommended activity created by NASA is called "How does an airplane fly?" and can be found at http://www.eweek.org/site/DiscoverE/activities/airplane.pdf.
- The purpose of the media article and the readiness questions is to introduce the students to the context of the problem. Depending on the grade level and/or your instructional purposes, you may want to use a more teacher-directed format or a more student-directed format for going through the article and the questions.
- Place the students in teams of three or four. If you already use teams in your classroom, it is best if you continue with these same teams since results may be better when the students have already developed a working relationship.
- Encourage (but don't require or assign) the students to select roles such as timer, collector of supplies, writer of letter, etc.
- Remind the students that they should share the work of solving the problem.
- As students work in groups, the teacher's role should be one of a facilitator and observer. Avoid questions or comments that steer the students toward a particular solution. Try to answer student questions with questions so that the student teams come to their own solutions.
- Watch the time and try to urge groups on if they are falling behind.
- If students seem to get off task and are not focusing on the data provided, direct them back to the actual data and task.
- If more follow-up is desired, after presentations and discussion,allow students to resume their groups and modify their models.
Assessment is an integral part of a model-eliciting activity. Each group is required to write a report to a "client" that describes their model, the reasoning that led to the model, and a justification of all decisions that are made based on the model. Group reports may be assessed for their clarity, completeness and the soundness of the explanations and justifications. In addition, instructors can decide if they wish to evaluate the students' presentations. Example rubric and scoring methods for student reports and presentations can be found at: https://engineering.purdue.edu/ENE/Research/SGMM/Problems/CASESTUDIESKIDSWEB/casestudies/airport/tools.htm
Follow-up questions to the activity may be used to assess student learning outcomes. For example,
- What do you think you learned from this activity?
- What questions do you have as a result of completing this activity?
Additional assessment items may be used depending on the purpose for using the activity and the nature of the course.
