Impact of Multimedia on Online Learning
What Impact does technology and multimedia have on online learning environments?
Recent advances in technology have opened the doors to new ways of proving content to students. We can now deliver video, audio, animations, interactive text, simulations and online assessments. We can deliver classes through various CMS. Students can access these websites on a computer, tablets and even their smart phones. The availability of these technologies can either positively or negatively affect student learning.
Often these technologies are used out of convenience as a way to entertain students or they are used by teachers because administration is pressuring them to use them. These situation will not lead to an increase in student learning (Tan et. Al. 2010). When implemented correctly multimedia can improve the online classroom environment by allowing access to more content in a more interactive interface. This will keep students engaged.
What are the most important considerations an online instructor should make before implementing technology?
Instructors must realize that there is more to creating an effective online course than merely uploading the information online (Tan et.al., 2010). The instructor needs to make sure that the technology being used is meeting the needs of the course. Technology should not be used just because it is there, it needs to meet be used to meet the objectives of the course. The instructor needs to carefully choose tools and communication techniques that will not only engage students but will meet the needs and accessibility issues of the student populations. (Boettcher & Conrad, 2010).
What implications do usability and accessibility of technology tools have for online teaching?
We have to remember that technology availability varies among students. We need to select technology that is available to most of the newer computer or technology systems. For example there are technologies that can be used on iphone, ipads but not on an android powered device. There are also some web tools that are only for PC or windows and will not run on apple computers. This is something as an instructor you need to be aware of.

As an instructor it is also important to be aware of accessibility issues for students with disabilities. This could including narratives of some to some of the written text. An instructor needs to be aware of backgrounds etc on the websites used for the classed. Many students with visual processing disabilities have difficulty reading black text on white backgrounds. Changing the backgrounds to a tan or yellow will make it accessible for these students with no additional changes needed to the content. Knowing the students will provide for dealing with accessibility issues.
What technology tools are most appealing to you for online teaching as you move forward in your career in instructional design?
I am interested in the K12 area of science. I have been using Junoed as a technology this year and the students like it much better than the textbook. Junoed lets me create lessons incorporating videos, animation, graphics text and audio. It also lets me create comprehension questions along the way to check for understanding. Students can work at there own pace through the lesson. It also allows me to create tests that are more interactive and interesting to the students.
I have just finished a unit where an option for their final project was glogster. Glogster is an online poster maker where students can incorporate multimedia into their poster.
Another technology that I find interesting is using a CMS. I have a classroom website with all the work but I am interested in transferring it into a CMS to better manage the assignments and class. I think the blogs and discussion would be a useful as a tool for an online class.
