SUMMARY
In Colombia, many institutions are in the firm quest of virtual learning environments to improve instruction, and making the most of online tools is clearly linked to offering quality learning. Thus, the purpose of this action research was to identify how the Cognitive Apprenticeship Model enhances online collaborative learning by using a chat tool. To describe the effectiveness of this model, five of its teaching methods were implemented in an eight-week period over one semester. Twelve beginning online English students enrolled in Colombia’s national vocational and technical training center participated in the study. Data was collected from surveys, chat transcripts, interviews and checklists, and analyzed through content analysis. Results reveal that modeling, coaching, scaffolding, exploration, and reflection may be implemented in a chatroom, developing a sense of collaboration. Learners also moved from guided instruction (modeling) to more independent learning (articulation), assuming the roles of experts. In conclusion, the six teaching methods of the Cognitive Apprenticeship Method enhance online collaborative learning not only because students work together to reach a common goal, but also because they can support each other’s learning through synchronous interactions when using a chatroom for this purpose.
