They begin by evaluating samples of existing cards, stationery, and postcards to determine what characteristics make them effective or successful. They then establish requirements for the design specifications they will use to develop their paper product. Next, students make their product and evaluate the effectiveness of their design plan. Finally, students establish ways to measure the quality of their products. Using these data, they evaluate their paper product and develop proposals for modifications.
Additional assessments provide further questions and challenges for evaluating student progress.
This is a challenging unit for students. Through firsthand observation and research, they develop an understanding of and appreciation for the importance of controlled testing and the process of hand papermaking. By experiencing the four basic steps of the technological design process, students begin to appreciate how scientists use technology to solve practical problems. These experiences provide the opportunity for students to discover that paper is an important renewable resource that continues to play a critical role in our civilization.
