In doing its part to celebrate Teacher Appreciation Day, Google has announced a preview of Classroom: a simple system for course work organization. The free software is nestled inside Google Apps for Education and serves up a quick and easy way to create/organize assignments, give feedback and communicate in real time with students. As you might expect, Classroom leverages Google Docs, Drive and Gmail in order to complete the aforementioned tasks, automatically creating folders in the cloud-based repository for each student when there's a new assignment. "Classroom is based on the principle that educational tools should be simple and easy to use, and is designed to give teachers more time to teach and students more time to learn," writes product manager Zach Yeskel. If you're an educator that's interested if giving it a shot, you can apply to be part of a limited preview. Google plans to release Classroom to any school using is education-minded apps program in September -- just in time for the fall semester.
