Collaborative Learning

We developed a workspace for collaborative learning on a multi-touch surface. Our users are school-aged children between the ages of five and twelve and their parents who wish to be more involved in their child’s education. Many parents using our system may not be well-educated, so our design allows parents to learn alongside their children.

Our goals are followings
* Foster the sense of collaboration between child and parent
* Educate parents so they can play a more effective role in helping their kids
* Support visualizing intellectual processes such as marking, sorting, and mapping relationships of information
* Enable conventional methods of compiling a report performed by using poster boards, articles, images

Our initial user studies indicated that writing a report is the most common homework assignment parents and children work on together. For this reason, our application deploys functionalities needed for compiling a report: searching, sharing, organizing, writing and editing.

The prototype is developed as a web application that can run on a multi-touch display. Input methods for our prototype are fingers or a light pen.

Parent and child can discuss together on a same report having their own workspace to write, edit, and search. The lower part of the interface provides individual work area, and the upper part of the interface supports collaborative finalization area.

The key functions of the system are (1)searching and (2) organizing

(1) Searching: Then the system processes search result into small cards, each related to one subtopic.
(2) Organizing: User can move around the information cards to organize an outline, and remove any cards that they think are not useful.

We evaluated the usability and effectiveness of our application. We ran comparative user testings comparing the differences between using word processor and the internet for writing a report about Martin Luther King. We ran post-task interview and questionairres to gain both qualitative and quantitative data.

Our observation, interview, and questionairre results show that people search and study by following the threads of information. Also, we our users found information of each topic displayed in cards are helpful. However, it appeared that some parts of interfaces are confusing and hard to use. Future work would be on refining the design and iterations.
