Jump to 65:46 to find out the sound of one hand clapping:
Video:A.S. Hornby Educational Trust Scholars’ presentation. Becoming an effective English teacher: who, what and where helps it happen?
Although the initial question to the speaker Hintsa Haddush from Ethiopia was not captured on the camera I imagine that the point he was making is that teachers supporting each other to develop (two hands clapping) is more powerful than isolated development (one hand clapping). The remarkable co-ordinated presentation by the 11 speakers essentially highlighted their experiences of informal teacher training via grassroots organization pitched at the local context.
Having admired the marvelously orchestrated speeches, the open Q&A session I found most interesting, shame more time was not devoted to that!
