/* Conole, Conele & Fill Learning and pedagogy taxonomy Reloaded by Daniel K. Schneider, TECFA, University of Geneva, i.e. I put this together from a variety of resources (papers, PPTs, Cloudworks, and DialogPlus + a bit of my own http://edutechwiki.unige.ch/en/Conole_and_Fill_learning_taxonomy

ftp/sfdp layout models

Optimized for the following kinds of dot commands: dot -s72 -Kfdp -Tsvg learning-taxonomy-fdp-2.map > learning-taxonomy-fdp-2.svg dot -s72 -Ksfdp -Tsvg learning-taxonomy-fdp-2.map > learning-taxonomy-sfdp-3.svg dot -s72 -Kfdp -Tdot learning-taxonomy-fdp-2.map > learning-taxonomy-fdp.dot

However:

• some attributes and even links (edges) needs to be ajusted for different layout models. E.g. sftp works best with a strictly hierarchical graph.
• some attributes are ignored, i.e. sfdp does not look at clusters or pos
• pos (positions) do not seem to work with sdfp

• /

// -- start of the graph definition

digraph learning_taxonomy {

// -- -- graph attributes

// A0 landscape page size - should print fine as poster, either A0 or A1 // Size in inches of an A0 page is 48.8x33.1 // Size in points would be "3355,2383" points (1 inch = 72 points);

// A0 landscape // size="46.8,33.1"; // A0 portrait page size size="33.1,46.8"; // A0 square // size="33.1,33.1";

// -- ratio is CRUCIAL // either fill or expand will extend the graph to the size defined above, else you will get a thrown together mess. fill expands in two directions, expand stops when the first is filled. ratio="fill"; // ratio="expand";

// -- Smoothing - spreads, but may create large overlaps // smoothing="spring";

// --- other global attributes to play with (some not working/useful) // some are ignored or overridden by various models/attributes

// -- quadType quadtree ="none";

// -- width/height ratio // aspect=0.7;

// -- spring constant (see also smoothing) // K=2;

// len=1;

// rankdir=LR; // -- Remove overlap but stretch too much, always also define scaling // streches out the clusters quite a lot, see the trees but not the forrest overlap="prism1000"; overlap_scaling=2;

// -- packMode (seems to have little or no influence // pts around a pack // pack = 50; // -- pack method // packMode = "node"; // packMode = "clust";

// repulsive force - use with SFDP to spread out repulsiveforce = 4;

// --- node and edge params

// nodesep and fontsize have a big impact for dot, nodesp only works with dot node [fontsize=14,fontname="Arial",shape=none,nodesep=2]; edge [arrowhead=normal,arrowsize=0.3]

1. #################################### the nodes and links ##########################################3
2. Arranged in some sort of depth first, since this allows to insert color tags

1. -- learning activity - THE ROOT - should be in the middle somewhere

"learning\n activity" [label="Learning Activity\n(Conole and Fill\nreloaded by DKS)",shape=ellipse,fontcolor=black,style=filled,color=yellow]; //,pos="1600,1200"

// top level edges - you can comment them out (in particular for FDP) /* "learning\n activity"->"context"; "learning\n activity"->"learning\n outcomes"; "learning\n activity"->"outputs"; "learning\n activity"->"resources"; "learning\n activity"->"roles"; "learning\n activity"->"tasks"; "learning\n activity"->"tools";

• /

1. -- -- non hierarchical links
2. REMOVE is you want a nice layout, add more if you prefer a forrest

/* "tasks"->"roles" [style="dotted"]; "tasks"->"resources" [style="dotted"]; "tasks"->"outputs" [style="dotted"]; "tasks"->"tools" [style="dotted"];
