“…This is in line with Menegale and Bier"s (2020) study, which found that teachers involved in online training on CLIL through a minority language were either not aware of the learning potential of online forum discussions or were not yet comfortable with them. In terms of social presence, while the e-trainer tried to implement strategies and prompts that would promote participants" sharing of information rather than their mere reflection on content understanding (Yoon et al, 2020), teachers mostly responded during the weekend with the forum being silent during the week. Also, trainees rarely commented on or referred to their colleagues" reflections and outputs, and only seldom opted to work collaboratively on practical tasks.…”

Research has already shown that designing instruction that simultaneously develops students’ content and language competences is fundamental especially, but not only, when students are educated in a second, foreign or additional language. Unfortunately, content teachers working in different types of bilingual education programmes hold varying beliefs about the role of language for and in learning and often struggle to successfully integrate language and content objectives. This is particularly the case of content teachers working in the Italian network of educational institutions in the world who struggle to support students to learn content through Italian as the language of instruction, but also tend to fail to recognize the importance of validating their linguistic and cultural background. In this context, the dearth of training is accompanied by a dearth of research on the effects of professional development courses.This paper aims to fill this gap by reporting on the effectiveness of a short online teacher professional development (OTPD) course aimed at supporting both primary and secondary subject teachers working in Italian international schools abroad to integrate content and language learning from a plurilingual and pluricultural perspective. Specifically, it explores teachers’ perceptions in relation to the design and implementation features of the course and to its effects on their beliefs, teaching practice, and professional identity.

“…The role of virtual bodies in co-presence and social presence illusions has been studied in the context of both CVEs and robotic telepresence. In a purely virtual setting, a realistic hand created the best social presence when communicating with sign language [61]. Tanaka et al [55] found embodying a physical robot enhanced social telepresence in remote face-to-face communication.…”

In this paper we examine the task of key gesture spotting: accurate and timely online recognition of hand gestures. We specifically seek to address two key challenges faced by developers when integrating key gesture spotting functionality into their applications. These are: i) achieving high accuracy and zero or negative activation lag with single-time activation; and ii) avoiding the requirement for deep domain expertise in machine learning. We address the first challenge by proposing a key gesture spotting architecture consisting of a novel gesture classifier model and a novel single-time activation algorithm. This key gesture spotting architecture was evaluated on four separate hand skeleton gesture datasets, and achieved high recognition accuracy with early detection. We address the second challenge by encapsulating different data processing and augmentation strategies, as well as the proposed key gesture spotting architecture, into a graphical user interface and an application programming interface. Two user studies demonstrate that developers are able to efficiently construct custom recognizers using both the graphical user interface and the application programming interface.
