| Sumario: | Recent studies exploring the effects of dynamic visualizations on learning compared with static visualizations have yielded mixed results. Procedural motor learning is one of the few fields in which dynamic representations have shown to be effective. Many of the studies have suggested that this advantage is mainly due to the activation of the "mirror‐neuron system." This study explores this explanation in physical education domain and analysed the effects of instructional media (video vs. photographs), showing tactical actions in basketball, on learning outcomes (i.e., game understanding and game performance), cognitive load (i.e., mental effort invested and estimated difficulty), and attitudes (i.e., attention, enjoyment, engagement, and challenge) in secondary school students. For all of the indicators, the results show that learning from video was more effective than learning from photographs. These findings have implications for the effective design of instructional media and provide confirmation of the superiority of video for teaching tactical actions involving the entire body. Lay Description: What is already known about this topic? Dynamic visualizations are ubiquitous tools to communicate temporal information.Evidence has showed that the effects of dynamic visualizations on learning compared with static visualizations have yielded mixed results.Dynamic visualizations may be particularly apt in teaching about motor skills, especially for tasks requiring hand manipulations, due to the mirror‐neuron system. What this paper adds? Using dynamic visualizations to portray information about tasks involving the entire body has a positive effect in learners, not only for their knowledge construction but also on their cognitive load and attitudes, compared with a more common instructional material (i.e., photographs). Implications for practice and/or policy: To select appropriate instructional media, physical education teachers should consider the limitations of learners' cognitive architecture.Dynamic visualizations are beneficial for teaching and learning contents involving human movements (i.e., basketball tactical actions), which supports the premise that the mirror‐neuron system helps overcome transitory information caused by human movement.
