Chapter Three Reflection

1.    Why is it important to learn about different technology tool when they are constantly changing?

It is important because we are always saying there is no need to learn it because it will be replaced in a year or less.   In that case, many of us would never learn technology so it could be actively used in our classrooms.  In addition, each time a new generation of technology or  software of device is released it commonly stems from a past technology.  In my opinion, it is easier to learn how to continue using updated technology compared to learning it all at once.  Also many students are up to date on all the new devices, they understand and can relate to this new technology.  The teacher should learn this new technology to build a connection into the students learning.

2.    Most desktop computers do the same thing as mobile devices, so why do teachers needs to use both?

Desktop computers take up a large amount of space within a classroom, and teachers are limited to the number of connects they have for them. Mobile device can allow some students to continue to do research while other students use the desktop. Mobile devices are more specialized allow students to gain the information they need away from the desktop and then return to incorporate in the information into their project or assignment on the computer.  In addition, mobile devices are smaller and can be difficult to see and use, and to have to worry about the fact they can break when dropped.  The desktop computer and the mobile devices both have pros and cons, but when use together I feel like the pros and cons balance out.   

3.    How can the cost of digital devices be justified when the functions they perform are often limited in number and scope?

Each one of these devices does have key functions and they work very well for the task in which they were developed for.  The text also discussed than devices and technology have about a five to seven year range, meaning these devices can to be used with older and newer technology.  Even if you feel like the cost is high on a device, if the teacher has planned how to use the device it can and will be able to use for many years.  The school will not lose money on these devices, as long as the devices are beneficial to the students and are used.
