I work abroad and my school is part of a group. I produce most of my own resources to meet the needs of the mostly non-native speakers of English, and the requirements of the exams I prepare students for. Our department works very effectively as we readily share resources with each other. We really benefit from the fact that we play to our individual strengths and interests. When new schools in our group were set up, we were asked to share our schemes of work with them, which we did. A visiting teacher asked if he could have all the resources for all the schemes, 'Because, well why re-invent the wheel?' he said. My thought was, 'Because the wheel took thousands of hours to create.' Perhaps mean-spirited but I do object to what seemed to me to be a somewhat shiftless approach from a new Head of Department. Also, my experience is that having to create my own materials has given me much more in-depth understanding of the subject matter I need to deliver. I do use some stuff I find online and am aware I need to post some free resources on TES.... and hopefully even be able to sell some in the future.
