Summarization Tool for VMT Preliminary Mockups
Murat Cakir2/6/2007
Main design issues
Where to host summarization support?– (1) In the existing w.b., (2) in a separate tab, (3) in a wiki page
When to initiate summarization?– During vs after the session, or both?
How to scaffold the summarization process– Provide instructions in the problem description– Suggest a format for the summary via headings
(need to decide how to word these instructions/headings)– Show example summaries– Ask a user to be the note taker or berry picker
How to motivate groups to summarize their work– Reducing the effort involved (reusing past content is key)– Using summaries as a solution submission process
Makes sense in a school context– Posting summaries to the wiki
Making findings public may encourage kids to provide explanations Can be coupled with a community rating mechanism
Where to host summarization support
Use the existing whiteboard space– [+] reuse existing content; collaborative summaries; ongoing summarization– [-] w.b. space is limited, so summary scaffolds may interfere with problem
solving work Include a dedicated summary tab
– [+] more space, clean organization of content – [-] reusing content requires transferring things across tabs; coordinating
actions across tabs may be difficult Use the wiki space
– [+] reproducing summaries from scratch may be valuable from a pedagogical perspective
– [-] hard to keep track of actions, need to reproduce content, disconnected from the chat space,
Hybrid approaches– Would it be possible to get the best of each option?– Potential key improvements over the previous Fest
Being able to reuse the existing content Being able to do summaries together
Summary tab concept
Summary tab is organized asan additional w.b.
Scaffolding with headings
Flexible organization
(The use of past tense sounds as if this should be done after the session)
Summary tab concept II
Summary tab is implementedas a set of editable text areas
Scaffolding with headings
Not as flexible as the w.b.
(The use of past tense sounds as if this should be done after the session)
Active summarization (scaffolding note taking during the session)
Extracted from our summary help page
The need for additional functionality
These mockups may require additional functionality:– Publishing content to wiki– Note taking support– Easy copy/paste across tabs (if implemented)
Posting summaries to the wiki
Alternative implementations– 1. Snapshot based tool
The selected area will be displayed on the wiki
– 2. Post the entire summary tab to the wiki– 3. Display the wiki page in the tab
Concert chat can only view static pages in a tab
Wiki postingMath Forum PoW: Shotgun Targets
Problem Description
Shotguns shoot a lot of little pellets. A shotgun can be adjusted so that when it's shot at a target, the pellets cover the target evenly. One of the steps in the adjustment process is to "pattern" the shotgun, to see where the pellets are actually going. This often involves shooting at a target about 40" x 40" that's 40 yards away. One kind of target is pictured above. Each of the eight regions inside the large circle has the same area. To check for even distribution, the pellet holes are counted to see if each region contains roughly the same number of hits.If the diameter of the large circle is 30", find the radius of the inner circle to the nearest quarter inch.
Team A’s Solution
10.61 is the radius of the smaller circle
Area of largeOis 225pi
3.14*15^2
225pi/8=88.3125
88.3125*4 equals 353.25 which is the area of the small circle
353.25=3.14r^2/3.14 /3.14112.5=r^210.61=r
A Topic-based organization
Note taking support I
Copy selected chat message to a textbox [-] potential conflict with referencing arrows
Take a note icon is stolen from http://www.iconarchive.com/category/application/kids-icons-icons-by-everaldo.html
1 2
Note taking support II
Append selected chat message to an existing textbox

Things to decide on
How to provide summary guidelines?– headings, dedicated tabs, or something else?
How should we word the guidelines? What are our pedagogical aims (ongoing/post reflection)?
Shall we setup a generic guideline, or shall we support problem specific guidelines as well?
How to connect summaries and the wiki pages. How to organize posts to the wiki?
– Topic pages, group pages
Extra: Changes to textboxes
The default background color– Should be easily discernable from the rest
Automatically adjusting the size based on what is typed Making the typing actions visible
– [-] increased traffic– [+] can help a lot to prevent conflicts
Worst case: user A starts editing, user B starts typing, A commits changes, then B commits changes. The resulting textbox only includes changes made by B
This will especially be problematic if we use textboxes in summarization in the tabbed version
– [+] can be useful during live demos such as equation manipulation etc.
Extra II: Alternative reference view (make the referenced object more visible)
Extra III: Label toolbar
Geometric objects: Point, perpendicular, angle
We probably don’t need allof these symbols,these are just a few examples providedby latex
We need to decide what extra symbols we need.
