Table 5 Stages and activities of making a simple outdoor paper microscope program for scientifically gifted students in the science education institute for the gifted

From: Development of an engineering design process-based teaching and learning model for scientifically gifted students at the Science Education Institute for the Gifted in South Korea

StageActivity
Defining the problem1) Discussing the characteristics of plant leaves by observing the front and back of a leaf in various plants with a loupe.
2) Observing stomata in the front and back of a leaf and their characteristics with an optical microscope and drawing what has been observed with an optical microscope..
3) Observing stomata in the front and back of a leaf with a paper microscope and drawing what has been observed with a paper microscope.
4) Comparing the paper microscope used with an optical one and sorting out the advantages and disadvantages of a paper microscope.
5) Thinking of what should be improved in a paper microscope when it is used in the outdoor field and sorting out the reasons for its improvement.
Ingathering informationUsing the search function on a smartphone to examine what kinds of portable microscopes are in the market.
Generating the solution1) Designing a more useful and simple outdoor paper microscope based on the detailed drawing of a paper microscope. (Do a simple sketch.)
2) Explaining your “simple outdoor paper microscope” designs and sorting out their positive (P), negative (M), and interesting (I) points.
3) Crating the best design for the simplest outdoor paper microscope based on the various designs of the members through a group discussion.
Implementing the best solution1) Making a paper microscope based on the ideas of the group. Observing stomata in the front and back of a leaf with the completed paper microscope and drawing what has been observed.
2) By comparing it with the old paper microscopes, freely discussing the performance and characteristics of the new paper microscope that the group has made with the members.
Evaluating the solution and reflecting1) Making a presentation on the paper microscope created by the group and evaluating the ones made by the other groups together.
2) By assimilating the contents of the group presentations, discussing the ways to make a “simple outdoor paper microscope” in a simple manner.
