The recognition that the development of Computational Thinking (CT) has been achieved in the educational systems of different countries implies, in some cases, the challenge of integrating its development into mathematics lessons. Although various proposals address the development of CT in the early years of schooling, educational robotics emerges as an alternative. The Bee-Bot robot has been recognized as an appropriate resource for the development of this type of thinking at an early age. For carrying out this qualitative study 25 articles were selected, based on a systematic research literature review, and analyzed to provide didactic orientation for the integration of CT in mathematics lessons with the use of the Bee-Bot robot (or similar). For this purpose, a thematic analysis method was applied to the selected research articles, focusing on the didactic explanations and suggestions for using educational robots to develop computational thinking. The themes used to analyze the data are according to the six dimensions (epistemic, cognitive, interactional, mediational, affective and ecological) of the didactic suitability proposed by the Ontosemiotic approach. The analysis allowed us to classify twelve didactic orientations according to the dimensions. Four of the twelve orientations refer to the epistemic dimension; three to the cognitive dimension; two are related to the interactional dimension; one to the mediational dimension, one to the affective dimension and another to the ecological dimension.

The social, scientific and technological development of recent years has encouraged the incorporation of computational thinking in the school curriculum of various countries progressively, starting from early childhood education. This research aims to characterize future kindergarten teachers’ traits of didactic-mathematical and computational knowledge presented when solving and posing robotics problems. Firstly, aspects of the mathematical and computational knowledge of the participants (97 students of the subject of Didactics of Mathematics of the Degree in Early Childhood Education at a Spanish university) were identified when they solved problems as users of the Blue-Bot didactic robot. Secondly, we analyzed their justifications for reflecting on the design of robotics problems. The results indicate that future teachers present characteristics of didactic mathematical knowledge when solving and designing robotics problems, although errors and am- biguities are evident, especially in the procedures and representations of the programming. These shortcomings significantly influence the didactic suitability of the robotics problems they design. From a future perspective, in the training of future teachers, it is considered relevant to incorporate didactic-mathematical and computational knowledge that allows them to develop logical, spatial and computational thinking.
