LetsGeddit:在线师生互动反馈平台是一个基于学生和老师在线沟通反馈的平台网站，教师可以把每节课的内容发布在该平台上，学生可以针对所有的课程进行在线测试并反馈给老师自己的想法和不懂的地方，这样就提高了教师和学生之间的交流，让学生更好的去理解老师的课程。Geddit引入了一个范式转变教育技术，学生通过这个工具提供并记录自己的学习过程中遇到的问题并反馈给教师，Geddit平台其实就是一个反馈系统，不仅使学生积极参与每堂课程的内容也帮助教师了解学生的学习情况，让学生学会反思自己的学习方式和强化知识的认知程度。在一些国外的学校里已经开始使用这个平台。I use Geddit to help students to gauge their levels of confidence in meeting lesson objectives while at the same time teaching students essential skills of active self-reflection in the learning process.Geddit introduces a paradigm shift in educational technology in which students are given an essential tool to provide and document ongoing feedback about their own learning process. In my experience, educational technology has primarily been designed and utilized as a content delivery system.Geddit is a feedback system that not only empowers students to actively engage in building a relationship with the instructor through the use of technology but also teaches essential metacognitive skills in which students learn to reflect on their own inner experience of learning. Students can be taught to engage in epistemological reflection and can have a record of their own learning process throughout the course of a lesson.I highly recommend this tool for any teacher who is passionate about teaching metacognitive skills and who is interested in increasing student engagement in using technology in the classroom.
