Mixed data collection.

Pre-Test	during the Experiment	Post-Test
- Executive functions (BRIEF, Gioia et al. 2013) - Cognitive-emotional skills (LEAS-C, Bajgar et al. 2005, semi-directive interviews with teachers) - Creativity (semi-directive interviews with teachers) - Oral production (audio-video recording with one camera from the language test in the classroom; semi-directive interviews with teachers). (See Section 3.4).	- Cognitive-emotional skills, creativity and embodied Language (Audio-video recordings * during the 4 workshops with the actor: 8 sessions)	- Cognitive-emotional skills, creativity and oral production (BRIEF, LEAS-C, testimonials of the teachers + of the actor, semi-directive interviews with the teachers and with the participant)

* We used 2 Canon XF105 cameras (A and B). The first one (A), static, was installed in a corner of the room. This camera was capturing wide shots. The second one, mobile, was shooting close-up, focused on the target child. Both cameras were synchronized. The microphone of Charles was wireless. All the audio streams were synchronized on both cameras, using a clap. These audio-video data help us to understand the links between the behaviour (language embodiment) and the oral production of the participants.
