The changes in educational practices proposed by recent works in the learning sciences, the curriculum reform in the Province of Quebec and the possibilities offered by information and communication technologies (ICT) to support collaborative learning are contributing factors to the transformation of learning environments. Aspiring to prepare future teachers adequately to this reality, the study reports accounts of the perception and use of opportunities put forward to enhance and sustain high-school pre-service teachers’ collaborative reflective analysis process. The concept of affordance, to which we attributed a social meaning to the one coined by James J. Gibson (1979) and refined by Donald Norman (1983) and William Gaver (1991), was used as part of our framework. Design experiment was conducted with nine groups of students from the Fall 2002 term to the Winter 2005 term. Field experience was anchored to a networked learning community context where constructivist and social constructivist perspectives are important. Students’ participation to this context was sustained by multiple possibilities of interaction, social and digital, all along their trajectory. Results show that most of the affordances put forward were perceived accordingly to what was designed. They scaffolded integration and participation of students to the networked classroom context and they encouraged deliberative and emancipatory reflectivity (Van Manen, 1977). In some instances, the reflective analysis process was transformed into knowledge building (Bereiter & Scardamalia, 1993). Changes have been noticed in the vocabulary used by pre-service teachers from one group to another. Moreover, results unfold the potential of sociodigital affordances for deep learning. We noticed an increasing level of complexity in the questions addressed by students over time. As we conclude this research, we propose implications for designing learning environment and teaching teachers.
