Transcript

  • 1. Created by: Charles White with inspiration and resources from NCDPI Division of Instructional Technology Global Positioning in the Classroom
  • 2. AGENDA and Objectives
    • What is a GPS?
    • What is Geocaching?
    • Why Use Geocaching in the classroom
    • I’m Skeered…now what?
  • 3. OBJECTIVES
    • Understand GPS technology and its daily uses
    • Understand the process of geocaching
    • Expose participants to integrating GPS technology into the classroom environment for the purpose of impacting student learning.
  • 4. What is GPS? When people talk about "a GPS," they usually mean a GPS receiver . The Global Positioning System (GPS) is actually a constellation of 27 Earth-orbiting satellites (24 in operation and three extras in case one fails). Source: "How GPS Receivers Work.” How Stuff Works.
  • 5. What is a GPS receiver?
    • Global Positioning System
    • Electronic device that can determine approximate location (within around 20-50 feet)
    • Coordinates are usually given in Longitude and Latitude
    • May include its own maps, built-in compass or voice navigation
  • 6. How GPS Receivers Work Imagine you are completely lost. You have been driving for hours and end up in a small town. You find a pleasant gas station and ask, “Where am I?” He says, “You are 188 Miles from Richmond, VA.” Source: Adapted from, "How GPS Receivers Work.” How Stuff Works. ?
  • 7. How GPS Receivers Work This is a nice, hard fact, but it is not particularly useful by itself. You could be anywhere on a circle around Richmond that has a radius of 188 miles, like this: Source: Adapted from, "How GPS Receivers Work.” How Stuff Works.
  • 8. How GPS Receivers Work You ask somebody else where you are, and she says, "You are 315 miles from Charleston, SC." Now you're getting somewhere. If you combine this information with the Richmond information, you have two circles that intersect. You now know that you must be at one of these two intersection points, if you are 188 miles from Richmond, VA and 315 miles from Charleston, SC. Source: Adapted from, "How GPS Receivers Work.” How Stuff Works.
  • 9. How GPS Receivers Work If a third person tells you that you are 157 miles from Greensboro, NC, you can eliminate one of the possibilities, because the third circle will only intersect with one of these points. You now know exactly where you are – Kinston, NC Kinston, NC
  • 10. WHAT IS GEOCACHING?
  • 11. WHAT IS GEOCACHING? GEO = meaning earth Source: http://encarta.msn.com/encnet/features/dictionary/dictionaryhome.aspx CACHE = Defined as a “Secret place for hiding Things: a secret place where a store of things is kept hidden
  • 12. Types of Geocaches This is the original cache type consisting, at a bare minimum, a container and a log book. Normally you'll find a tupperware container, ammo box, or bucket filled with goodies, or smaller container ("micro cache") too small to contain items except for a log book. The coordinates listed on the traditional cache page is the exact location for the cache. A multi-cache ("multiple") involves two or more locations, the final location being a physical container. There are many variations, but most multi-caches have a hint to find the second cache, and the second cache has hints to the third, and so on. A virtual cache is a cache that exists in a form of a location. Depending on the cache "hider," a virtual cache could be to answer a question about a location, an interesting spot, a task, etc. The reward for these caches is the location itself and sharing information about your visit. Source: http://www.geocaching.com/about/cache_types.aspx
  • 13. Types of Geocaches Puzzle Cache: This form of cache can involve complicated puzzles you will first need to solve to determine the coordinates. The only commonality of this cache type is that the coordinates listed are not of the actual cache location but a general reference point, such as a nearby parking location. A letterbox is another form of treasure hunting using clues instead of coordinates. In some cases, however, a letterbox has coordinates, and the owner has made it a letterbox and a geocache. Visit www.letterboxing.com An Earthcache is a special place that people can visit to learn about a unique geoscience feature or aspect of our Earth. Earthcaches include a set of educational notes and the details about where to find the location (latitude and longitude). Visitors to Earthcaches can see how our planet has been shaped by geological processes, how we manage the resources and how scientists gather evidence to learn about the Earth. Source: http://www.geocaching.com/about/cache_types.aspx
  • 14. Types of Geocaches These are caches that use existing web cameras placed by individuals or agencies that monitor various areas like parks or road conditions. The idea is to get yourself in front of the camera to log your visit. The challenging part, however, it that you need to call a friend to look up the web site that displays the camera shot. You will need to have them to save the picture to log the cache Locationless caches could be considered the opposite of a traditional cache. Instead of finding a hidden container, you are given a task to locate a specific object and log its coordinates. A scavenger hunt of sorts, it involves collecting waypoints of various objects around the world.
  • 15. On the Hunt for Caches Searching for the hidden
  • 16. Traditional Caches Caches can come in all different sizes
  • 17. Small or Micro Caches
  • 18. Virtual Caches and Multi-Stage Multi-stage caches will take you to 2 or more locations and may include many different types of containers
  • 19. Virtual Caches and Earthcaches
  • 20. Steps to Finding a Cache 1. Research 2. Prepare 3. The Hunt 4. The Find
  • 21. Rules of the Cache
    • Respect the Environment
    • Respect Others
    • Respect the cache
    • Dress Appropriately
    • Protect Yourself
    Dress Appropriately Respect Others Respect the cache Respect the Environment
  • 22. Our School Rules
    • Caches are NEVER placed in a parking lot or road
    • Caches are NEVER placed anywhere dangerous or yucky
    • Caches that are near the woods may be just inside the edge of the woods (no more than 3 feet in)
    • Last cachers of the day, bring in the containers
  • 23. Exploring the GPS Receivers On/Off Backlight Zoom in Zoom Out Create POI (Point of Interest or Waypoint) Nav Button Escape Menu Joystick/Enter
  • 24. Exploring the GPS Receivers The GPS Plotter Screen Your Current Location The cache The Scale Breadcrumb Trail
  • 25. Other Screens Location Screen Tells current Location in Lat/Log, Accuracy, Elevation Compass Screen Shows compass as well as Sun and moon location, and direction to cache Satellite Screen Shows how many satellites are being tracked by the receiver
  • 26. TIME TO HUNT
  • 27. Entering in POIs
    • POI: Point of Interests - a location designated by a set of coordinates and stored in a GPS receiver to be used later. Also called a waypoint
    • Breadcrumb trail – A digital representation of the path you took as you are moving. It will be depicted in dashes - - - -
    Terminology:
  • 28. Entering in a POI
    • Press the “Mark Button” (Push pin icon)
    • Use Joystick to move to the box called “name”
    • Use joysticks to enter the name, select OK when you are finished.
    • Use Joystick to move to the box called “Location”.
    • Move Joystick Up/down to change numbers and left or right. Press Enter to go to the next line
    • Select the Save button.

  • 34. Why Use Geocaching in the Classroom?
    • Engage digital natives
    • Use 21st Century tools
    • Promote multiple intelligences
    • Integrate curriculum
    • Excite learning
  • 35. Engage digital natives “ Today’s students … have spent their entire lives surrounded by and using computers, videogames, digital music players, video cams, cell phones, and all the other toys and tools of the digital age.” Prensky, M. 2001. Digital Natives, Digital Immigrants .
  • 36. Use 21st Century tools There are many tasks in our daily lives and our society that can be solved by the use and development of technology. By using the GPS in education, we stress a connection between everyday learning and problem solving and the development of technology
  • 37. Promote multiple intelligences WHERE DO YOUR STUDENTS FIT? Whether your students like sketching and puzzles-building, speaking and writing, problem solving, using their hands to create or build, rhythms and motion, or working with others, geocaching can work in your classroom http://www.ldpride.net/learningstyles.MI.htm#is Multiple Intelligence Visual/Spatial Verbal/Linguistic Logical/Mathematical Bodily/Kinesthetic Musical/Rhythmic Interpersonal
  • 38. Integrate curriculum Use Geocaching to enhance the delivery of education, not replace the content.
  • 39. Excite learning Your students will be excited and involved when caching. The experience will be new and rewarding for them.
  • 40. I’m skeered….now what
    • How to check out the GPS units
    • Getting Support
    • What am I responsible for?
  • 41. Parting Thought: Technology is offering an opportunity, not an end. Reducing the teacher fear-factor is a huge piece of the puzzle.* * Max Frisch
