Introduction
MI
Introduction (LSI Quadrant I):

Say, “Technology is shifting to become a more integral part of our daily lives.
Computers continue to become smaller, more powerful, and more functional.
However, in this evolution, there is a growing shift to mobile computing.”

Ask, “What are some of the different types of mobile devices we use today?”

Ask, “Why do you define these devices as being mobile?”

Ask, “Can anyone name some of the different ways these devices
communicate and transmit data?”

Say, “By the end of this session you will be able to identify what constitutes a
mobile device. We are also going to learn about operating mobile devices
and gain a working knowledge of how these devices can communicate with
one another.”

Application
MI
Guided Practice (LSI Quadrant III):
The teacher will define the different types of mobile devices and give
examples of the varying classes of mobile devices.
Groups will choose a class of mobile device and research where devices
are heading and the role wireless communication will play in the
functionality of that mobile device.
MI
Independent Practice (LSI Quadrant III):
The student will pick a wireless technology (Bluetooth, Wi-Fi, or cellular) to
research and list some of the benefits to the technology as well as its
potential limitations.
Summary
MI
Review (LSI Quadrants I and IV):
Ask the students these questions:
1. “What are mobile devices, and how are you able to identify one?”
2. “What are some different wireless technologies used for mobile
devices to communicate with other electronics?”
3. “Name some of the different security measures that personal
wireless systems employ.”
4. “Name different types of user interfaces that mobile devices utilize
for a user to operate the device.”
Evaluation
MI
Informal Assessment (LSI Quadrant III):
The instructor will monitor student progress during the independent practice
and answer questions groups may have as they research their selected
wireless technology. This exercise should help the instructor to see if
students are grasping the different wireless technologies and how they
apply to mobile computing.
MI
Formal Assessment (LSI Quadrant III, IV):
The instructor will utilize the Mobile Devices – How They Operate Exam and
Exam Key.

Extension
MI
Extension/Enrichment (LSI Quadrant IV):
The instructor may ask the students to visiti visit two to or three local
wireless providers, obtain service brochures, and then compare and
contrast the different wireless service providers. Students should also look
into what the different types of technologies and wireless mobile devices
each provider offers.
