In this study, the authors examine the possibility of reconciling the two seemingly opposing approaches of Instructionism and Constructivism in SI skill acquisition pegadogical training. The authors propose a Collaborative Learning integrated model that builds on the foundations of the Insructionist trainer-oriented approach which has proved its effectiveness in transferring declarative knowledge to learners. The proposed integrated model leverages the valuable elements of the Constructivist leaner-centered approach that gives learners a voice in learning while allowing them to build on their individual strengths. The authors think an integrated model provides a balance between the approaches. Such balance is deemed to be suitable to respond to the global reality of the twenty first century. The paper provides an overview of the various pillars and elements in SI learning and training process, a review of the historical development of SI training, and a look at the Kobe College OJT program that provides training in a real audience setting. The results suggest that the weaknesses of the Instructionist approach can be remedied by the structured and thoughtful blending of the Instructionist and Constructivist approaches in the Collaborative Learning environment.
