- Digital competence is a skill associated with the 21- century abilities essential to contribute to today’s and tomorrow’s digital and technical environments. Computational Thinking (CT), which is a thought process for problem-solving, is one of the emerging trends that make up digital competence. In our explorative study, we have used educational robotics with four pre-service teachers during their four- week s placement at different preschools. We applied three distinct and complementary approaches to design and conduct this study: Systems Thinking (ST); Technological Pedagogical Content Knowledge; and Computing Pedagogy. Our findings are categorized in two main perspectives: pre-service teachers and children. In the pre-service teachers' perspective, the participants indicated that their educational program lacks specific content and activities related to digital competence, CT, and programming. Despite the initial pre-service teachers’ thoughts on improvement of children's CT concepts, the findings show that CT practices such as collaboration and trial and error were developed. From the children’s perspective, the empirical findings illustrate that digital competence and CT development vary depending on the age of the children; whereas logical thinking and pattern recognition are skills that were present along the whole age range of children (ages 2-6), other CT skills like algorithmic thinking were developed among older children only (aged 5-6). We learned that an ST approach can behelpful, as multiple factors are involved in the practice. It reveals the underlying features of the situation that emerge when components of the system interact with each other.

- One major challenge the educational community is facing relates to how to effectively integrate computational thinking (CT) concepts and ideas into a particular school curriculum. Acquiring CT-skills by means of STEM offers rich opportunities within students ́ education which may lead to learning gains. Previous research has shown that, to maximize the appeal and potential of CT learning environments, a precondition must be set first. The materials used must invite problem-based, inquiry-based and self-discovery learning, must be used without creating misconceptions and, above all, must give students the opportunity to acquire knowledge that can be directly transferred to everyday practice in an accessible manner. All the above puts demands on teachers who carry out learning and teaching in these environments. The EU funded TACTIDE project has tried to incorporate relevant curricular components into a coherent task, implementing assignments and challenges across different subjects and curricula of three different European countries. Based on the analysis of each national curricula, common topics have been identified and sub-scenarios have been developed. These sub-scenarios have been conceived to promote the integration between the topics mediated by CT. To achieve this objective, a greenhouse scenario has been conceptualized and designed towards teaching CT, by the use of microcontrollers such as the BBC micro :b it and the Calliope Mini, as an overarching STEM-topic. Using available sub-scenarios, a Moodle-course for teachers was developed for daily school activities to which other subjects in the core curriculum were interconnected in order to integrate CT skills and abilities. Scalability across different school levels and heterogeneous groups of learners, especially focusing prior knowledge, have been considered important design elements.

- In many countries worldwide, Computational thinking (CT) is now considered as a fundamental skill for dealing with the challenges of the 21stcentury society. One of the most common ways of imparting CT knowledge in K-12 education is by teaching programming and coding, as it requires applying a set of concepts and practices that are essential for thinking computationally. However, learning to program can be challenging and it may take time to develop these skills in the context of school activities. Thus, complementing formal K-12 education with after-school or other types of informal learning activities aimed at fostering CT concepts and practices among young students can be an alternative approach to develop these skills. During the summer of 2021, we carried out a series of workshops in the context of a summer camp taking place at a public library, organized by a local municipality in southern Sweden. These workshops (with a total teaching duration of 20 hours in one week) consisted of activities where children aged 11-14had to assemble wheeled robots and then program them using a visual language to make them execute different types of tasks and challenges. The outcomes of our study show that roughly one third of the participants managed to program the robots with code that made use of CT core concepts, such as conditionals, loops, and logical operators, among others. The rest of the children did not manage to successfully apply these concepts and thus they could only manage to program sequential linear scripts. We argue that learning to program and understanding some of the main concepts, which are for the most part very abstract, is a process that takes time and thus, extracurricular activities can be an effective method to complement formal education and help young students develop their CT and programming skills.
