As it can be seen, active methodologies like the Flipped Classroom are not completely viable without technology. At least, we can admit that it makes teaching easier.
Making a compilation of the ones that have been already commented we have the following:
Edmodo has been one of the greatest discoveries of this year. Its simple use and the advantages it offers as a tool make of it the perfect application for teachers and students.
Another one which is definitely useful for active classes is Blendspace.
It allows you to create your lessons in different ways, facilitating the elaboration of material for our flipped classrooms.In addition, there is available a wide range of already done classes, so if you are beginning to implement a methodology like this, and you are lost where to start, this may be a good starting point.
Moving on into more specific applications, I would like to add Kahoot!
This application helps the teacher in the elaboration of quizzes or questionnaires, in a superb wrapping, that is to say, in an absolutely engaging and appealling way.
Apart from the questions, you can add to them videos, photos, songs, you can decide the time students have to answer, they can work individually or in teams… The options are infinite, and that is why is a perfect tool to introduce in our lessons.
It can be use to review, to remember some concepts or even to evaluate.
An application similar to this one is Socrative, but personally I prefer Kahoot!
This three are only an example of how useful technology can be in our classes. But, nowadays with the internet and all the technological progress, it is impossible to imagine the amount of applications and webpages that are out there waiting to be discovered. My advice? Take your time, explore and you will find something interesting.
