In this paper I show how I study my teaching, as a student on a Masters degree (M.Sc.) programme in Education and Training Management (e-learning strand) at Dublin City University. As I explain my teaching as a History teacher, I show how I locate myself within Information and Communications Technology (ICT) and within education in Ireland. The source‑literature examines critical thinking, social software and collaborative online‑learning environments. These help me to understand the processes in my research question. I seek to explore my embodied educational values, and use them as a standard of judgement for my research. I work in a collaborative‑dialogic way with all the research participants, establishing an online-classroom in order to help them to think critically. I come to several conclusions about collaborative online-learning, critical thinking and my own educational values. I believe I create a space for students to think critically through my enthusiasm and the students’ ease in an online-environment. I show that positive educational change is possible when using a collaborative dialogic approach to teaching and learning.
