Group Trajectory
Session I
The team starts in session one as a very engaged group of four participants who take up on the grid-world task very actively. Very little participation by fg in the first session. A total number of 7 questions are posted in the chat. Five of them make it to the whiteboard as textboxes with answers. The complete list of questions posted in chat (C) and on the whiteboard (W) is:
- (C/W) What's the minimum distance to get from A to B? (dc)
- (C/W) What is the maximum distance from point a to b if u can only travel on each line once? (mt)
- (C/ ) maximum distance: how about travelling in a spiral around the perimeter? (dc)
- (C/W) How would you get to B in 11 steps? (dc)
- (C) What if you could travel diagonally across the squares? can we modify the problem to think of new questions? (dc)
- (C/W) How about if you can't travel in the same direction more than once in a row? (dc)
- (C/W) What is the least number of lines to get to each of the 4 corners and to point B? (mt)
- (C) What is the maximum number of lines you can go on without let the lines touch? (mt) (i ment distance srry not lines)
Multiple grids are used to explore different questions. Last one is used a lot to explore paths and count them. The session ends because they realize the time set for the activity has expired (#1MATHWHIZ: moderator, it is after 9). Some interesting ideas in the post-session chat (e.g. Sancho: well some people didnt participate as much; #1MATHWHIZ: can we some questions that the other groups thought of)
Session II
Many users tried to log into the chat environment but did not appear to succeed. No session was held.
Session III
Tp reports that she had been trying to join the two previous session but was unable to do so because of technical problems (templar: i just got my chat environment to work i wasnt able to properly log on the last two times). Mt joins later and apologizes for not showing up last time (#1MATHWHIZ: hey srry i wasnt on last time). Mt explains that his school had an event that conflicted with the chat (#1MATHWHIZ: no one from my school was able to attend because of a school function). Fg tries several times to join but fails (fogsurrounds12: it is irritating). The moderator attempts to initiate the session but Mt gets disconnected (#1MATHWHIZ: srry i got disconnected 4 a sec) several times and the moderator decides to move Tp to team 1.
Templar, had started thinking about question 3 where the edges of the grid are connected (templar: if you connected the edges of a graph that would make a 3-d object like a cylinder would it?) and drew a cylinder with two points on it corresponding to the same points on the flat grid. When he joins team 1, they are also working on question 3, so he starts participating right away (templar: could you imagine the grid as a piece of paper and you can connect the two sides makin somethin like a cylinder) and proceeds to draw his cylinder again.
Session IV
Dc meets again Fg, both of whom had participated in session I, but missed the last two sessions (davidcyl: what did I miss? / last two times). The moderator asked them if they recalled the grid world and whether they had worked on a formula for the distance between two points on the grid. Dc didn't think that they had a formula so they work on that problem and solve it (davidcyl: yeah. so the formula would be: d (distance) = |y2 - y1| + |x2 - x1|). After that, they work on the "grid-world circle" until the time runs out.
Group composition: Unstable
Session 1: sn dc mt fg (+o)
Session 2: *NS*
Session 3: mt tp *canceled. tp moved to Team 1*
Session 4: dc fg
*NS* No session held
(+o) Others participants in and out
Grid-World vs. Diagonals
Session 1: Four very engaged participants, all work on grid distances, lots of whiteboard work Session 2: -- Session 3: -- Session 4: Both "types" of distances are explored. Distance "as the crow flies" is presented as "not necessarily the shortest distance between two points, but it is still a type of d". Work non the grid-world circle.
