The document discusses the functions and features of a Garmin GPS unit. It describes the unit's ability to provide location using coordinates, navigate between waypoints, plot routes between multiple points, and automatically log tracks. Additional features include a screen, buttons, memory capacity, and waterproof design. The document also covers the affordability and accessories of GPS units, strengths of using them in education, limitations, and ideas for integrating them into physical education classes such as geocaching.

3. Functions:
• Giving a location: its ability to accurately triangulate
your position based on the data transmissions from
multiple satellites. It will give your location in
coordinates, either latitude and longitude or Universal
Transverse Mercators (UTMs). UTMs are used to
pinpoint a location on a map.
• Point-to-point navigation: allows you to add waypoints
to your trips. By using a map, the coordinates of a
trailhead or road or the point where you're standing,
you can create a point-to-point route to the place
where you're headed.

4. Functions:
• Plot navigation: allows you to combine multiple
waypoints and move point-to-point. Once you reach
the first waypoint, the GPS can automatically point you
on your way to the next one.
• Keeping track of your track: Tracks are some of the
most useful functions of portable navigation systems.
You can map where you've already been. This virtual
map is called a track, and you can program the GPS to
automatically drop track-points as you travel. This can
be done on land or in a nautical setting and allows you
to retrace your steps.

5. Features:
• No batteries are included with the purchase of
this unit. Any "AA" batteries will work in this
device.
• High-sensitivity, WAAS-enabled GPS receiver
provides peak performance in any
environment
• Lightweight and waterproof

6. Features:
• High-contrast 2.1-inch X 1.1-inch screen with
bright back lighting
• 5 buttons located on either side of the device
for one-hand operation
• Store up to 10,000 waypoints, 20 routes, and
10 saved tracks for later use
• One Year Warranty

7. Affordability and Accessories
• Depending on the type of GPS you can spend
as little as $100 or as much as $600 on a hand
held GPS.
• If you were to purchase GPS units for a
classroom a less expensive beginner model
like the Garmin Etrex H. This model is perfect
for the outdoor enthusiasts on a budget.
• Everything you need except the batteries
comes with the GPS

8. Strengths
• By using GPS receivers in the classroom we are helping
to create student-centered learning environments
Traditional Learning Environments New Learning Environments
Teacher-centered instruction Student-centered learning
Single sense stimulation Multisensory stimulation
Single path progression Multipath progression
Single media Multimedia
Isolated work Collaborative work
Information delivery Information exchange
Passive learning Active/exploratory/inquiry-based learning
Factual, knowledge-based learning Critical thinking and informed decision-making
Reactive response Proactive/planned action
Isolated, artificial context Authentic, real-world context

9. Limitations
• Could become expensive
• Is primarily and outside activity
• Limited Menus
• No maps down loaded
• Takes time to understand how to use the GPS
(not user friendly)
• Only really accurate if you are moving

10. Integrating GPS into PE
• Geocaching is the next best thing! Not only is
it a great way to get your student to learn how
to navigate using maps and GPS units you can
also incorporate a little fitness too or
introduce your students to a lifetime activity!
