In this article, we present the outcomes of the pilot phase of a multi-case study being conducted in Cyprus. The study aims to develop and propose universal design principles of using a Flipped Classroom (FC) approach as a pedagogical structure of Inquiry-Based Learning (IBL) applicable across primary education context in Cyprus. The universal design principles refer to the general guidelines most primary teachers can follow when designing their lessons by integrating the two instructional models of FC and IBL, and to the specific pedagogical strategies teachers can use for different school subjects to motivate and improve their students' learning processes through Networked Lerning (NL) opportunities. Providing teachers with those principles (i.e. guidelines and strategies) is particularly important given the lack of instructional experiences of Cyprus primary school teachers in implementing a FC model in their classroom practices and a wide range of subject matters that those teachers need to teach. There has been a limited focus, in previous research concerning the FC model, on its effectiveness within the primary education context and also in relation to the NL technologies used. The pilot study aims to primarily address this research gap, develop the IB-FC model and present potential benefits of using the IB-FC model in primary school context. The learning process based on the IB-FC model includes pre-class, in-class and after-class activities. During the pre-class phase, students explore the learning content provided by the teacher at home and obtain an entrance ticket which is used during class time for the IBL facilitated by a series of classroom activities, which require the students to be creative and collaborative. Forums and other features of online learning platforms are utilized so as to promote NL through collaboration and communication. The after-class phase involves self-assessment procedures and the completion of an e-portfolio page. After the first pilot-nature of iteration of implementing the model, participant students’ learning experiences and perceptions on this new learning scenario were collected through focus groups and reflection forums. Based on our findings from the pilot study, the IB-FC framework including important pedagogical principles and additional instructional tools have been developed and offered to seven primary school teachers in the current stage of our multi-case study, through which the framework will be further developed and refined.
