Education is a field that constantly changes, which dictates the need for continuing teacher professional learning and development. Teacher professional learning and development can be divided into two categories: formal learning/ development and informal learning/development. This paper focuses on the experience of the presenters as coordinators of a large language section in a tertiary education institution, as this gave them the chance to develop professionally through informal learning, without attending any formal training sessions. Both coordinators did not have any previous experience in coordination, but they decided to keep a positive outlook on challenges and weaknesses, turning them into opportunities and strengths with the aid of technology. The experience of coordination will be presented using a Strengths, Weaknesses, Opportunities, and Threats/challenges (SWOT) framework of analysis. The present paper will report on this experience and how it helped the presenters develop professionally, and will also discuss the role of the use of online tools in the process.
