Developing educational and testing material stretches the imagination and exercises every writing muscle. Careful attention must be paid to each detail, as a single mistake can discourage the learner. To keep things interesting, the content must be diverse in terms of context. It must also be clear, concise and consistent. And it has to match the learner's capabilities while at the same time enabling them to advance.
I started writing educational material for students and teachers in the 1990s. Around that time I contributed to a series of textbooks for schools in Tokyo, Japan and assisted in developing a curriculum for the Peace Boat. While most of the educational content I write these days is for TOEIC preparation guides, I also work on Eiken test and other material.
You can check out my publications and other projects I've worked on below.
