Berthold Lowenfeld Blindness imposes the following limitations: • In the range and variety of experiences • In the ability to get about • In the control of the environment and the self in relation to it. (1948) Craig L. Phillips, MS Ed. COMS
Why GPS???? “I feel like I'm "cheating" somehow, when I don't have to keep track of what street is what, where it's located, what direction I'm heading, etc... it frees my mind up to concentrate on other aspects of orientation...and then, listening to the GPS as I'm riding in a car, realizing the breadth of this world that is outside my car window I have heretofore never gotten to interact with…amazing, simply amazing.” KM age 39 Craig L. Phillips, MS Ed. COMS

Student Considerations • Interest • Perceived utility • Maturity > Age • Cognitive ability • Dexterity • Route concept • Stamina • Techiness is useful, but not essential. Craig L. Phillips, MS Ed. COMS
Data > Opinion Craig L. Phillips, MS Ed. COMS
Device Considerations The difficulty or simplicity of learning how to use a system must work for the student first and the teacher second. Mike May It’s not about you… It’s not about you… It’s not about you… Craig L. Phillips, MS Ed. COMS

Begin at the Beginning… • Start with the component parts • Assemble/Disassemble • Orient to the device • Follow with the key describer mode • GPS limits/parameters • Movement versus static position Craig L. Phillips, MS Ed. COMS
Begin at the Beginning… • Start with the familiar • Then walk, listen, and reference • Learn the language • Repeat the message • What is the information… • Where is it provided… Craig L. Phillips, MS Ed. COMS

Mapping Street Open Area Craig L. Phillips, MS Ed. COMS
Landmarks/Waypoints • Street and Open Area Mapping • Know where you are • Multiple landmarks can be set at the same time/same spot. • Always set a landmark at the beginning of a route. Always set a landmark at the beginning of a route. Always… Craig L. Phillips, MS Ed. COMS
Landmarks/Waypoints • Pair with physical reference points • Label noun first, then adjective • “Smith High School, East Door…” • Address entry results Craig L. Phillips, MS Ed. COMS
Landmarks/Waypoints • Nurture environmental literacy. • Fill in the gaps to develop the gestalt of the area. • Set before and after hazards, headaches, and irritations. • Practice renaming, deleting, and unsetting as a destination. Craig L. Phillips, MS Ed. COMS
Point of Interest = POI • Point of Interest • Preset on Maps • TeleAtlas • NAVTEQ • Use POI rich environments to begin instruction Craig L. Phillips, MS Ed. COMS
Point of Interest = POI • Where is the “spot?” Craig L. Phillips, MS Ed. COMS
Routing Modes • Pedestrian • Distance parameters • Motorized • Time parameters Craig L. Phillips, MS Ed. COMS
Routing Reliability • Self-created routes • Landmarks and Waypoints • POIs • Address Entry Craig L. Phillips, MS Ed. COMS
Sources of GPS Error • Signal slows as it passes through the atmosphere • Signal multipath occurs when the GPS signal is reflected off objects such as tall buildings or large rock surfaces before it reaches the receiver. • Number of satellites visible-buildings, terrain, electronic interference, or sometimes even dense foliage can block signal reception • Receiver clock errors- receiver's built-in clock is not as accurate as the atomic clocks on board the GPS satellites. Craig L. Phillips, MS Ed. COMS
Problem Solving • Always warm up the device. • Reset… • Routing Hiccups • No GPS coverage • Turn back • Off route • Silence Craig L. Phillips, MS Ed. COMS
Teaching Considerations • GPS usage demands solid fundamental O & M skills for the final +/- 50 feet. • Everything is relative. • Context clues/concepts must be practiced. • Organizational parameters • Time and distance • Solicitation of aid • Don’t tell…question. Craig L. Phillips, MS Ed. COMS
Teaching Considerations A GPS device is a where and when tool... Craig L. Phillips, MS Ed. COMS
Teaching Considerations Much better… Craig L. Phillips, MS Ed. COMS
Teaching Considerations • Preview routes for “blackholes.” • Take a cheat sheet on lessons and use it. • Use multiple SD cards. • Settings menu • Earplugs and headphones are not recommended when traveling. • Assume nothing and be open to learning. Craig L. Phillips, MS Ed. COMS
Teaching Considerations Showing is better than telling… Craig L. Phillips, MS Ed. COMS
Teaching Considerations • Let your student show you and others. • Inservice classmates, teachers, and parents. • Encourage borrowing. • Get lost on lessons. • Motorized guidance Craig L. Phillips, MS Ed. COMS
Teaching Considerations Monitor glare interference Craig L. Phillips, MS Ed. COMS
Teaching Considerations Dual lesson with Trekker Breeze and Garmin Oregon 450 Craig L. Phillips, MS Ed. COMS
Curricular Integration • Conceptual Development • Literacy • Physical Education • Geography • Mathematics • Social Competency Craig L. Phillips, MS Ed. COMS
The Continuum • “Outer space.” • “Mommy, we need to turn here” • “Directing a cab driver to my destination gave me control.” Craig L. Phillips, MS Ed. COMS
