FOREGROUND: 'Tensions' Global tension in Hunter’s mapping work: When is mapping more effective/efficient than text in task presentation/performance?
FOREGROUND: 'Tensions' • Uses of Concept Mapping (really) • In scenarios where text is too dense or too clumsy for easy learner access to information structures. • 2. For abstraction. • 3. For a focus on information-linking functions. • 4. To downplay text orchestration.

Novakian maps (Novak & Cañas, 2006) are type 3 maps, having textured link dyadic elements. Associational Directed link Textured, somehow directed link
Novakian maps, with their textured link dyadic elements, can be used to represent arguments. The rules of operation for Novakian maps may be defined as: Rectangles (nodes) contain concepts. Rectangles are joined by labeled lines (propositions). Propositions are usually uni-directional. The label in the middle of a proposition is called a linking phrase.
Clarify this study’s purpose in terms of content: Aim of this design process: -to create tasks and devices that aid the TAW learner in perceiving/using information structures: -argument structure, -knowledge structure (following Mohan (1986) and Hunter (2002)) and -message type (central message, background information).
Clarify this study’s purpose in terms of form of language/information
Novakian maps are suitable for low-text representations of rhetorical moves in logical argument. The rules of operation for Novakian maps may be defined as: Rectangles (nodes) contain nouns/noun phrases. Rectangles are joined by labeled lines (rhetorical device signals). Propositions are usually uni-directional. The label in the middle of a proposition is called a linking phrase.

RSTmapping Bill Mann’s Rhetorical Structure Theory (RST) uses various sorts of "building blocks" to describe texts. The principal block type deals with "nuclearity" and "relations" (often called coherence relations in the linguistic literature.) www.sil.org/~mannb/rst/ RST links are rhetorical devices.
Cmap tools http://cmap.ihmc.us/ Novakian links are syntactic devices.

Study: task constraint work Phase 1: unconstrained associative mapping Learners made association type concept maps of the content of a text. To force summarization, a limit of 10 nodes was imposed. Performance was strongly uniform in terms of node content. Generally the learners used the lexical units (e.g. subject-verb) found in the text. ppt 1: associational mapping
Study: task constraint work Phase 2: unconstrained Novakian mapping Learners map the same text again, using Cmap software. Object: "try to represent the argument in the Niiho paper," which was described in the article. Maps were highly varied (chaotic variation) in content and in link type.
Study: task constraint work Phase 3: constrained Novakian mapping Learners mapped the text a third time, again using Cmap software, but with only the argumentation links shown below.

Learner product was quite uniform in choice of links from the array above. Map structure and content varied relatively little. ppt 2: argument mapping
