The initial technological pedagogical and content knowledge (TPACK) model was theorised on seven clearly identified factors. However, many studies have failed to empirically identify these seven factors, and elements influencing TPACK level, such as national context, gender, and age, remain unclear. The study is focused on teacher educators' TPACK as one of the most important elements in schoolteacher training. The main goals were to test the validity of the initial TPACK seven-factor model in a cross-national analysis context and to identify factors influencing the TPACK perception. The sample was composed of 574 teacher educators coming from a total of eight schools of educational institutions from six countries. A 26-item questionnaire, based on a four-point Likert scale, investigated the seven factors of the TPACK model as independent scales. It was administered online and anonymously. A confirmatory factor analysis using the robust maximum likelihood method and Kruskal-Wallis chi-squared tests were performed. The study showed four major results: 1) a relative stability of the seven-factor model structure across countries; 2) the relative differences of university teachers' TPACK perceptions across six countries in Europe and Asia; 3) the dependence of age and TPACK factors; and 4) an independence of gender/academic level and TPACK.

The aim of this paper is to track down elements of self-regulated learning in a massive open online course regarding social capital. Specifically, the study is oriented to explore the relationship between feeling of belonging to an online community and individual and collective regulation of learning. For this aim, a combination of two already tested scales was operated, adapted for the research interests of this study and administered to a sample of MOOC participants. Several structural equation modelling analyses demonstrate that co-and self-regulated learning strategies lead to MOOC achievement (final exam score), and social capital is only a moderator of co-regulated learning (collective evaluation of content and collective decision-making) but not for selfregulated learning (individual environment control).

International audienceThe paper is set in socio-material farming to offer a way of conceptualising actions and interactions of children in preschool involved in the understanding of scientific concepts. A model of early science education about the physical phenomena of shadow formation is implemented in group work in a French context. The research involved 44 children (13 females and 31 males) of 5–6 years old. The research design was organised in three video recording steps: pre-test, teaching session and post-test. We focus on the analysis of nine teaching sessions to investigate children’s ‘understanding’ of shadow formation. A descriptive and qualitative approach was used. In particular, we have identified three main categories (the interaction of the children with the tools, the embodiment and verbal dimension)—with respective indicators—to perform the analysis. From the results, all the categories explored seem to influence each other: all material, human and social dimensions contribute to the children’s understanding of shadow formation. Also we have identified some elements that can serve as a potential source of improvement of the teaching session on shadow formation. Finally, the research provides insights on how to improve science activities in preschool with the aim of supporting early understanding of physical phenomena
