Wicked Problem - How can distance be taught to students ensuring that they understand the concept so it can be used in a real-world setting?
Wicked Problem Solution - For students to successfully grasp the concept of distance, we will teach them geocaching. Using a mobile device with GPS capabilities, students will learn how to download latitude and longitude coordinates, search within the community, and input this information into a computer mapping application such as Google Maps or Google Earth.
Technological Content Knowledge - Distance will become a tangible variable that can be manipulated for understanding by having students explore with GPS devices and compare with maps on the Internet.
Technological Pedagogical Knowledge - By using either dedicated GPS units or mobile devices in addition to computer mapping applications, these teaching strategies will allow students to have a practical, real-world experience in calculating distance.
Pedagogical Content Knowledge - In order to help our students understand distance, I need to know what they know. This will be accomplished by discussing physical, topographic, and road maps. Students will be encouraged to ask questions in order to acquire the same basic understanding of maps. I will use this information to explain the hemispheres, latitude, and longitude. This will directly lead to understanding GPS. By combining these elements, students will have a concrete representation as we go outside and use our GPS devices to find pre-determined locations.
