As specificity of our research, the individual learning viewpoint is concentrated at the identity of studying techniques and on supplying a multi-dimensional textual complexity version, while the collaborative learning size is headquartered at the review of members’ involvement, in addition to on collaboration assessment.

Our process according to complex ordinary Language Processing ideas presents a qualitative estimation of the educational strategy and complements figuring out as a “mediator of studying” via offering automatic suggestions to either freshmen and lecturers or tutors. the most advantages are its flexibility, extensibility and however specificity for masking a number of levels, ranging from studying school room fabrics, to discussing on particular themes in a collaborative demeanour and completing the suggestions loop by way of verbalizing metacognitive thoughts.

Prior to this moment of appropriation, the word does not exist in a neutral or impersonal language […], but rather exists in other people’s mouths, in other people’s concrete contexts, serving other people’s intentions” (Bakhtin 1981) Moreover, dialogue can be also perceived within a broader and more abstract perspective as being capable of grasping multiple valences: ‘internal dialogue within the self’ or ‘internal dialogue’ (Linell 2009, ch. 6), ‘dialogical exploration of the environment’ (Linell 2009, ch.

More important, inter-animation processes appear among these threads, following patterns similar to those of counterpoint in polyphonic music (Trausan-Matu et al. 2006; Trausan-Matu and Rebedea 2009). 32 3 Collaborative Learning Fig. 5 Multiple discussion threads highlighted through the explicit referencing facility (Holmer et al. 2006, Trausan-Matu, 2010) From an educational perspective, a typical considered case is that of small virtual groups using chat systems for learning together (Stahl 2006b; Trausan-Matu et al.

Although the complexity of an utterance may vary greatly from a simple word or interjection to a set of inter-twined utterances or even to an entire novel (Bakhtin 1986), our analysis adheres to Dong’s perspective of separating utterances based on turn-taking events between speakers (Dong 2009). Therefore, introducing a new point of view or intervention from a different participant divides the discourse by changing the inner, ongoing perspective of the current speaker. At a more fine-grained level, words seen as the constituents of utterances provide the liaisons between utterances and deepen the perspective of other’s interventions into one’s discourse: “When we select words in the process of constructing an utterance, we by no means always take them from the system of language in their neutral, dictionary form.
