7108 Module 2

I've included three tetrads. The first one is the present, the second one is a step back, and the third one is the future (maybe).

(I had trouble with formatting, sorry)

7108 Mod1 - Emerged Technolgies

One of the emerging technologies I’ve experienced in the past few years is web-based learning. In particular, the learning I’m focusing on is self-paced and delivered via the Internet. This type of instruction, where the student receives direction and interacts with the information presented on the computer screen, is designed to enable students more autonomy with their instruction and the pace moves at a level they are comfortable with. With instant feedback and remediation built in, this approach can give the students a sense of control that they may not normally have in a traditional classroom.

Of course, this may mean the absence of a teacher or facilitator. This can create problems especially if the software has not been prepared to foresee all possible difficulties the student may encounter (a distinct possibility), and is likely the greatest challenge with this type of education delivery. Internet availability may also be a challenge. Although it’s taken for granted that the Internet is everywhere, the reality here is that many homes in lower socioeconomic depressed areas are not “connected” so a place to get connected would need to be provided. Another issue is the ability of the local internet provider to have the capacity to accommodate a large number of users. As Thornburg points out, the capacity needs of just ten years a go pales in comparison to the needs of today and schools in particular have not focused on increasing capacity to the levels needed (2009)

One of the social ramifications of web-based learning is that rural students can gain access to learning that may have previously been out of touch. Also, the likelihood of access to a larger number of students would be realized as server space typically allows for a greater number than the typical classroom. Cost would like fall as the need for staffing would decrease, typically the largest expense, because less teachers and support personnel are needed for e-learning than for brick-and-mortar schools.

To improve this technology, having a learning specialist familiar with the curriculum of study and the program being utilized available via webcam to assist the student would be a good start. Also, flexibility as to the equipment required, i.e. portable Internet enabled devices as well as desk top computers, so students could access the “classroom” with few limitations and in ways that match their access ability.
