“…The researchers who support the use of these tools in teaching argue that the animations are better than the static pictures used in scientific books or for illustration in cell biology courses, that they are a way to illustrate the teacher's explanations during a course, that they can facilitate the synthesis of the biological phenomena studied or their ability to develop self-learning skills in students (Azizah & Widiartin, 2019;Berney et al, 2015;Kiat et al, 2020;Roehling, 2018;Xiu et al, 2019;Yang et al, 2019). Other researchers have mentioned the fact that the use of these video animations increases students' motivation and their cognitive and emotional engagement (Ekberg & Gao, 2018;Qaddumi et al, 2021;Steiner & Mendelovitch, 2016) and makes learners active (Geri et al, 2017;Ramsay & Terras, 2015).On the other hand, researchers who disagree with the use of video animations in teaching argue that these animations can generate a cognitive load for young learners, especially if the speed of these animations is fast (Berney et al, 2015) or if they greatly simplify the phenomenon being studied (Stith, 2004).…”
