Enabling pre-service teachers to develop a critical view of their practice and to acquire the higher order inquiry skills necessary for pedagogic research has been and continues to be a challenge. The present study presents a unique intervention in the training of pre-service teachers in research skills (research literacy) using a Problem Based Learning (PBL) approach. The intervention is implemented in two different Learning Communities (LC), one online and the other blended. Both immediate and long-term effects of PBL are investigated as are the effects of social and direct scaffolding within the LCs.The study focuses on transmitting the following Research Literacy (RL) skills: identifying and defining a problem, formulating a research question, and designing a research method. The findings indicate an immediate effect upon all RL skills in both LCs. The long-term effect appears only in the online LC and only for two RL skills: identifying and defining problems. Additionally, there is greater use of social scaffolding in formulating and designing a research study in the online LC than in the blended learning community. Those findings are then interpreted in terms of retention capacity and scaffolding in blended and online LCs.building depends on heightened levels of interaction and on harmonization of blended interaction channels. While this principle was maintained in the online LC of the current study, it was probably missing in the blended LC.Participants in the blended LC were alternately requested to create learning interactions in traditional and online formats. Probably the inconsistency of the communication channels and their differing patterns confused them, reducing the efficiency of the interpersonal interactions. This in turn led to significantly lower frequency and quality of both direct and social scaffolding as compared to the online LC.
Practical implications, future research, and limitationsThe main purpose of this study was to compare an online Learning Community to a blended LC, focusing on students' ability to assimilate the link between Research Literacy and pedagogy. We had assumed that the pedagogic communication which took place in the blended environment would achieve significantly greater internalization of the knowledge and skills of RL than that of the pure online environment (Willcoxson et al., 2011; Bettaz et al., 2016). This assumption was based on the claim that multichannel communication improves outcomes in declarative knowledge, cognitive flexibility and high-order skill acquisition (Park, 2011). However, our expectation was not only not confirmed, but we found that online-based pedagogic communication yields better results for most aspects of RL and in the social interactivity in the virtual forums.On the theoretical level, this study offers important insight into evaluating PBL communication with different kinds of scaffolding and social interaction in a RL context. On the practical level, this study provides a perspective on an innovative method of assimilating the link b...
