Vygotskian computer-based learning activities (VCBLA), implemented by means of collaborative scripts, usually involve: - a flow, which guides the whole activity; - collaborative tools, such as chat and/or forums; - integration of the online platform with external tools or applications. The aim of this project is to engineer learning activities in order to allow their dissemination in the scholastic context. It is, therefore, an application of the results of educational research and research in mathematics education. However, the dissemination could facilitate the acquisition of further data for research regarding the effectiveness of the designed and implemented VCBLAs. More specifically, the underpinning idea is to create user-friendly interfaces (UFI), which allow teachers, even non-experts, experiencing these educational activities with their students. These interfaces could be used to foster the development of skills both in business and professional training fields. More precisely, this project has three main goals: [br][br][b]Goal 1[/b]: creation of new knowledge consisting in a methodology that allows to engineer VCBLA by means UFI; [br][b]Goal 2[/b]: production of UFI prototypes implementing and validating the methodology of Goal 1, to be disseminated among schools in the local area. [br][b]Goal 3[/b]: assessment of users’ acceptance of prototypes. [br]
