Communication donnée le 31 Août 2017 lors de la session J 10 : Instructional Design, Learning and Instructional TechnologyComprehension of Text and Graphics - C; International audience; Few previous research showed that camera viewpoints differences played a role in learning hand procedures from videos. However, learning videos on hand procedures showing only single viewpoints have been investigated, for example face to face vs. over the shoulder views. Further, the effect of seeing the human model's face and the effect of showing hand actions have also been studied. The results of these research are not always consistent. The goal of the present research was to investigate the effect of mixed camera viewpoints on learning a medical hand procedure from a video. Within a pretest-posttest paradigm, 43 students from a French institute of nursing education had to learn a complex hand procedure from a video showing an expert nursing teacher who installed an indwelling catheter in a closed system. Three videos conditions were compared showing the hand procedure respectively from (i) a face to face view (FtF), an over-the shoulder view (OtS) and (iii) an alternation of face to face and over the shoulder views (MixW). The students were randomly assigned (N =10-11) to one of four groups: the three experimental viewing conditions (FtF, OsS, MixW) and a control condition, without video. Pre and post-test consisted in the demonstration of the hand procedure in a full scale simulation room fully equipped. Results showed that learners in the mixed viewpoint (MixW) group performed better than the other groups (FtF, OsS, MixW and control condition). Learners in the FtF and OsS groups had betters scores than learners in the control group.
