This article describes a methodological approach to conditional reasoning in online asynchronous learning environments such as Virtual-U VGroups, developed by SFU, BC, Canada, consistent with the notion of meaning implication: If part of a meaning C is embedded in B and a part of a meaning B is embedded in A, then A implies C in terms of meaning [Piaget 91]. A new transcript analysis technique was developed to assess the flows of conditional meaning implications and to identify the occurrence of hypotheses and connections among them in two human science graduate mixed-mode online courses offered in the summer/spring session of 1997 by SFU. Flows of conditional meaning implications were confronted with Virtual-U VGroups threads and results of the two courses were compared. Findings suggest that Virtual-U VGroups is a knowledge-building environment although the tree-like Virtual-U VGroups threads should be transformed into neuronal-like threads. Findings also suggest that formulating hypotheses together triggers a collaboratively problem-solving process that scaffolds knowledge-building in asynchronous learning environments: A pedagogical technique and an built-in tool for formulating hypotheses together are proposed. © Springer Pub.

This paper proposes we grant graphemes - the constituents of words in situations of discursive constructions - the status of meaning carrying units, in much the same way Vigotski granted the phoneme such status in relation to the spoken word. This paper also seeks to analyze these units in singular manifestations in acts of appropriation of the written language, based on data created by a six-year-old child in a discursive situation. To perform this task, we also referred to Bakhtinian studies on the role of the other in our relation with language. Since the analysis indicated spelling approximations to records found in old Portuguese, historical grammar research of Portuguese was also used. The findings indicate the diversity of reference sources for letter selection by the child, according to its function in the composition of the word.
