Case study
Using videos and images during lessons
The image below shows the constructional features of a miniature circuit breaker (mcb).

| Triple pole siemens mcb |
Notice on the image the brand of the mcb, students were asked to go online and explore different brands of mcbs and choose one that they will use to complete a particular job. Included in the task was an analysis of the brands eg advantages and disadvantages, the cost and location of the object for purchase.
After the exploration and reasearch the students were to upload their findings and conclusions onto a blog and also embed a few images of mcbs that they found to be relevant in this task, comment on peer blogs was encouraged as well.
The outcome of this activity would be a better understanding of the constructional stucture of the mcb. Students will also compare and contrast the different brand available on the market which is beneficial for the practical activities they will have to accomplish using the object.
Conclusion
Students can use blogs to complete an assessment, in a class of say 12 students if one comes up with three different points and share it on the blog a total of 36 points will be covered in a session, this is extremely difficult in a classic classroom setting whereby the teacher has to draw on the whiteboard and explain everything, that has the disadvantage on one way communication and time becomes the main focus .
Use of Video in Learning
The video below shows the constructional characteristics of an mcb, the above activity can be used for the video as well, this time it's a single pole circuit breaker.
Another example of uploading the same video is shown in the next blog.
I have also explored affordances of technologies in learning which are images,audio and video in scoop.it, follow the link below to have a read:
