- One of the challenges that newcomers to Google Earth and Google Maps often encounter is how to decide to use the application and when to use it. This Google presentation summarizes the main features of each App.
- Google has produced an interactive game to help beginners quickly understand how to use Earth. It’s the most interactive way to become familiar with Earth. Click here to go to Google Earth: Learn.
- For beginning users of Google Earth, as well as advanced, Google Earth lessons is an outstanding resource.
- The Google Lit Trip Website the most comprehensive Google Earth-based lessons resource. It cotains galleries and downloadable Google Lit Trip files from grades 5 to Higher education. Make sure you check it out and download some of those .kml files

is a software tool that allows users to visualize the network of interactions resulting from discussion forum posts and replies. The network visualisations of forum interactions provide an opportunity for teachers to rapidly identify patterns of user behaviour – at any stage of course progression. SNAPP has been developed to extract all user interactions from various commercial and open source learning management systems (LMS) such as BlackBoard (including the former WebCT), and Moodle. SNAPP is compatible for both Mac and PC users and operates in Internet Explorer, Firefox and Safari.
Developed by the University of Wollongong, this sociogram can
visualize the discussion forum in an LMS (Blackboard, WEBCT, MOODLE, SAKAI..) and displays the student-student, teacher-student interaction in mind map. Names of students/teacher can be displayed. Also, each node size and link thickness refer to the frequency of the posts.
I gave it a try on one of discussion forum on one of my Moodle Websites with my students. I chose a a discussion forum at the beginning of the year where students had to post their first Hellos using Voki as their voice avatar, and they had to comment on each other’s post.
1. First, I Downloaded SNAPP
2. This took me to a new page where I dragged a bookmarklet onto my browser’s bookmark tool. I followed the steps depending on my internet browser(Firefox in this case). And yes, SNAPP resides on your internet browser and not a stand alone desktop application
3. Then, I went to the discussion forum of my Moodle Website. I made sure that the discussion forum is in the nested view so that SNAPP can read the posts.
5. I scrolled down till the end of the nested discussion forum. I waited for a while. This might take longer time depending on internet connection and pc speed. Also, make sure that Java is installed on your browser. The visualization of the discussion forum will soon appear with contributor names, the connection of posts, the size of nodes and link connection depending on post frequency , and a menu of filtering options on the right.
You can also view the statistics and export it as GraphML format or VNA File format.
As you can see in the above discussion forum visualization, I, the teacher is in the middle of the web with the most posts and most interactions are between students and me, with some posts among students themselves.
This is a typical view of a discussion forum at the beginning of a course where students get to know each other and are reluctant to comment on each others’ post. This stage is where the teacher posts a lot. However, as the course goes along this discussion forum should change to reflect a different type of student behavior with a more student-student behavior, unless it is teacher-centered.
What this software can do is to reflect the student-student teacher-student interaction behavior in terms of links and frequency.
However, the software does not ensure that the discussion forum is engaging and fulfills the course requirements. A content analysis is needed for this.
SNAPP can be used as an insight into interaction behavior. For example, if one wants to explore teacher presence and social presence this might be useful. The teacher would for instance base some informed decision on how the behavior of interaction is shaping, is it teacher-centered? Is there a student who lurks and does not participate? Is there a pattern of discussion in particular stages in the course that should have been patterned otherwise?
What do you think? What other insights can we get from SNAPP?
