Your own blog

From now until the end of our regular classes, we will be working, in an attempt to revise and consolidate what we have learnt throughout the year, on creating your own ITGS blog, focused on the social impact of the use of technology.
Working in pairs, you will create a new blog in Blogspot. This blog will feature news articles, videos and any other resources that deal with the social and ethical impact of the use of technology. The theme of your blog will be the impact of technology on individuals and societies, and your target audience are web surfers who are interested in analyzing those implications and want to know more about the impact of technology.
You are expected to write a short commentary on the resources posted, and create a discussion thread for each article that you publish. You will be expected to respond to user comments on each of these threads.
You will be assessed on the quality of the posts, how they successfully cover the syllabus, and how you respond to user comments, thus encouraging a positive discussion on the topic.
Your blog must contain at least one post per topic posted on the ITGS Blog.
Individually, you are expected to post at least three comments per lesson on other people’s blogs, and send a copy of each comment to itgs.sass@gmail.com
By the end of the lesson today, you have to send an email that contains:
- Names of the students in the group and the URL of the newly created blog.
- User name or Google account which you will use to post comments.

By Wednesday next week, you should submit, in a Word file:
- The name and grade level of the teacher you have interviewed.
- A summary of the interview.
- A specific reference with regards to whether the teacher thinks the game is applicable or not, and the reasons for that.
