This stage was done in two that is, it was tested with students a and peer who also teaches the same course.The Sreencast was uploaded on the department Learning Management System (Claroline). The original size on disk was 480MB which was too big for upload and download. The file was converted to MP3 format and reduced size to 71.3MB the further compressed using Winrar to 12.7MB which could be uploaded on the LMS or sent on email. Students could access the file on their own from the LMS or save it on other flash disks so that they can play the video on their laptops or even use it whilst they are in the Computer Science Lab.

A discussion group was created on Facebook so that students can post any questions on the aspects they are struggling with in programming. Other students or the educator could respond and also make any other contributions. The Screecast was also supposed to be uploaded on Youtube, but this failed because of the size. During the process I noticed that the amount of time spent whilst retrying to upload was unrealistic and if at all the video could be uploaded, it would also be difficult for students to download it as compared to when they are downloading from the Learning Mangement System which is on the Intranet. Students were also able to post emails directly to the educator for any assistance using the university email system. This also helped students on block release who could email from their workplaces for assistance.

As the main objective of the online intervention was to improve on the learning delivery to students as well as to assist students with differing levels of understanding by scaffolding, the results could come out best when a variety of technologies were merged to get the best results. Using a Screencast, a student could be able to self-pace their studies as well as iterate concepts that are difficult to understand to them many times until they get a clearer picture of each aspect. The Facebook Forum and Learning Management System Forum would also help to scaffold a student’s understanding to a concept.
