Computational thinking and coding are key competencies in the 21st century. People with Down syndrome need to be part of this new literacy. For this reason, in this work, we present an exploratory study carried out with students with Down syndrome with cognitive ages of 3-6 years old using a tangible robot We applied the observational method during the sessions to analyze the participants' emotional states, engagement, and comprehension of the programming sequences. Results show that people with cognitive disabilities can acquire basic programming and computational skills using tangible robots such as KIBO.Informatics 2019, 6, 25 2 of 20 using the fundamental concepts of computing" [9]. The interest in this term continues to grow, as does the number of initiatives to promote its effective introduction in schools [10][11][12][13][14].Coding, programming, and computational thinking constitute a way for people to express and share their ideas [15]. In this sense, these skills can be integrated into almost any class activity, with or without technology, as a new literacy and a new way of thinking, integrated with other parts of the curriculum.Furthermore, educational robotics is a didactic approach that can be integrated into different educational environments [16]. This integration can be done through the use of programmable robotic devices and the application of project-based learning methodologies. The acquisition knowledge process can be improved through research and experimentation [17]. Robots can be used as physical tools for the development of cognitive skills through play, creativity, and the resolution of challenges [8]. Interaction with robots occurs physically when children manipulate the tool itself, play with it, and observe its movements [18]. Robots have appealing features and functions for children that able to maintain children's attention for a longer period of time, improving their performance, their ability to concentrate, and their cognitive flexibility, but it has also been found that a robot alone is not motivational enough [19]. The motivation for the use of the tool emerges from the activity, the problem or challenge to be solved, or from the story that the children represent using the robot [20]. For example, converting a robot into a character with a mission to fulfill or a role to embody engages children in different types of activities, offering them the opportunity to explore the possibilities of the environment [21].If the motivation for children to use a robotic tool is born of the challenge to achieve, it is possible to take advantage of this great opportunity to create learning environments and situations with clear curricular objectives, through which children feel strongly attracted and committed, encouraging their curiosity, creativity, and active participation, and in which they have an opportunity to build their own learning, enriching the experience while gaining digital and computational skills [4]. Furthermore, robots can also be very helpful in the teaching-learning of prog...
