In order to be well-educated citizens in the 21st century, children need to learn computing in school. However, implementing computing education in schools faces several practical problems, such as lack of computing teachers and time in an already overloaded curriculum. A solution can be a multidisciplinary approach, integrating computing education within other subjects in the curriculum. The present study proposes an instructional unit for computing education in social studies classes, with students learning basic computing concepts by programming history related games using Scratch. The instructional unit is developed following an instructional design approach and is applied and evaluated through a case study in four classes (5th and 7th grade) with a total of 105 students at a school in (omitted for submission). Results provide a first indication that the instructional unit enables the learning of basic computing concepts (specifically programming) in an efficient, effective and entertaining way increasing also the interest and motivation of students to learn computing.

AbstractThe field of design practice and design education is reaching out to address problems that cannot be solved by introducing a single product or service. Complex societal problems such as gender inequality cannot be solved using a traditional problem-solving oriented design approach. The specific characteristics of these problems require new ways of dealing with the dynamics, scale and complexity of the problem.Systemic design is a design approach integrating systems thinking in combination with more traditional design methodologies, addressing complex and systemic problems. This paper reports a systemic design approach in an educational context for the case of academic gender inequality. We show the way the problem was addressed and how design students were invited to take a systemic perspective, provide integrated interventions and take first steps in providing instruments for implementation. We conclude with the learnings from this case study, both on the process and the results.
