ClipIt (http://clipit.es) is a social-collaborative web-based learning platform developed at the Rey Juan Carlos University within the European project Juxtalearn (Ref. FP7-ICT-2011-8). This social network is designed for video-based learning but can be used with any type of educational content learning. The project aims to arouse the curiosity of students and improve compression of thresholds concepts for the understanding of the subjects through a process where the student takes an active role. Students are the creators of the videos uploaded to the platform themselves and become authors of educational materials for their peers. Furthermore, it provides teachers with authoring tools to design activities revolving around threshold concepts, in which students are asked to perform and compose videos. ClipIt uses a reflective learning approach, scaffolded task-based activities, and peer feedback to stimulate engagement of content viewers and authors.

The learning process is structured around a set of steps. The teacher proposes threshold concepts to students for performing an educational video including its script, recording and editing phase. Teachers can also provide background materials related to the threshold concepts for easing the elaboration of the videos. When the educational video is ready, students can make it available to their peers in order to visualize and to discuss both the strengths and weaknesses. It helps them to improve and to understand what mistakes had or aspects have been overlooked. This reflective process and discussion process takes place in a safe environment and it supported by rubrics designed by the teacher.

During this process, students take an active role in their learning process that encourages their creativity while using educational technologies. Different teaching methods are applied to achieve a more active and creative teaching. These innovative teaching methods are flipped classroom because students is the creator of the videos where threshold concepts are explained in order to help the understanding of them to their peers; blended learning and peer review owing to the learning process are guided; mobile learning because students can work from different devices, project based learning as a project is proposed to students and work on it during different tasks, and finally, collaborative and cooperative learning at different levels (small working groups and joint class).

This platform has been used in several educational experiences in different countries: United Kingdom, Portugal, Sweden, Germany and Spain. More than 2000 learners from different educational levels (Primary School, Secondary School and University) have been involved in video-based learning activities using this platform.
