I am part of and see daily the frustration that teachers have being bombarded with tools clearly untouched by teachers and where teachers have never been asked for their opinion and have certainly never been engaged or approached in the early development stage.
In response to this massive problem, I created a platform where EdTech developers can actually collaborate and share their products with our community of willing teachers. They get real time feedback and expert eyes on their products in the early stages. In your words, we hope that there will no longer be an excuse to not 'engage with teachers.' You can check out our site:
We have 500 teachers onboard and they are taking on paid jobs for the summer to Tinker with new tools and take part in meaningful interviews and user testing studies. Their input leads to iterations of Edtech products that meet real classroom needs and solve real problems. It is a lot of fun and rewarding to both sides of the community, both teachers and EdTech entrepreneurs.
