Computational making
Introduction
Computational making combines computational thinking (in this case computational design) with digital fabrication.
In a conference paper (Johnson, 2017: abstract) [1], Johnson argues, that “the maker movement generates much more stuff to consume. A school may purchase a 3D printer for educational purposes, only to have its student-makers simply download and print other people's models without learning to make their own. To prevent this kind of situation, educators must capitalize on the maker movement in ways that facilitate what we call computational making, which involves both meaningful cognition and the making of artifacts.”. Put more positively, computational making is a motivating way to learn programming and other technical skills. “In maker culture, the ability to program along with other technical skills [...] includes fun activities through personally fabricated projects.”[2]
More formally, Knight & Vardouli (2015), define "computational making" in two steps: “On a conceptual level, we use ‘making’ as a keyword for action-centric, process-oriented attitudes toward the production and use of material things”. “With regard to the ‘computational’ in Computational Making, we interpret the term broadly as the use of formal, mathematical systems, theories, and methods, as well as tools and technologies developed on the basis of such systems. Computation includes systems and tools for designing (for example, generative and parametric systems, or visualization and modeling systems) and for making (for example, fabrication and construction systems). Computation may include, but is not limited to, the use of digital computers.” (Editorial Computational Making)
Computational design is sometimes use as a synonym of computational making or as its most important part (e.g. as in Introduction to computational design). According to Jacobs and Buechley [3], computational design "is the practice of using programming to create and modify form, structure, and ornamentation''. The term also can refer to a more generative philosophy, e.g. as proposed in Computational Design: The Future of How We Make Things is Tech-Driven. Finally, Paul Jeffries in What is Computational Design? describes Computational Design as the change in the medium of design expression from geometry to logic.
The origin of educational computation design is the Logo programming microworld [4] from which many other environments are derived. Later, Logo was interfaced with Lego bricks and other hardware. As of today, there exist several environments inspired by Lego, e.g. Scratch. Some of these are used together to program small robots. All of these have in common the idea to provide a so-called microworld that allows exploring computational thinking, science and design problems. "Making" adds another dimension, being able to create a physical design. Jacobs and Buechley (2013) [3] claim that the combination of computational design and digital fabrication offers many exciting possibilities for art, design, and creative expression.
Advantages of computational design and making vs traditional design
Jacobs and Buecheley [5] identify the following benefits that can extend traditional design techniques: “
- Precision and automation: Computation affords high levels of precision and allows for automation of repetitive tasks, enabling the rapid development and transformation of complex patterns and structures.
- Generativity and randomness: Computation allows for the programmer to design algorithms which when run, allow for the computer to autonomously produce unique and often unexpected designs.
- Parameterization: Computation allows users to specify a set of degrees of freedom and constraints of a model and then adjust the values of the degrees of freedom while maintaining the constraints of the original model.”

Making to teach computational thinking
Chytax, Tsilingiris and Diethelm (2019) [2] argue that "The creation of computational artefacts as a means of expression could be an exciting way to develop computational literacy [8] . Modern digital fabrication tools like 3D printers, laser cutters and CNC routers enable the manufacturing of computational designs of complex geometries and structures. Furthermore, combining digital fabrication with coding can open new ways to promote design and creativity [3] ."
Jacobs and Buechely (2013) [9] organized a short lamp creation workshop and a longer fashion workshop. In the fashion workshop, participants used the Codeable Objects software, a Java-based library for Processing. “Participants were given 10 days to conceptualize and construct a garment using a combination of computational design, digital fabrication, and traditional sewing and crafting”. They found that “the overall feelings of engagement and empowerment fostered by these experiences indicate that computational-design tools for novices could serve as a powerful way to positively change people’s understanding of the relevance and applications of programing, while fostering technological and aesthetic literacy in the process”
Learning theoretical and cultural background
Most discourse on computational making is rooted in constructionism. For example, Mori (2017) [10] cites Kafai and Resnick (1996:1) who defined Constructionism as follows: “Constructionisms uggests that learners are particularly likely to make new ideas when they are actively engaged in making some type of external artifact - be it a robot, a poem, a sand castle, or a computer program - which they can reflect upon and share with others. Constructionism involves two intertwined types of construction; the construction of knowledge in the context of building personally meaningful artifacts.”
Computational making is often related with arts-based approaches. E.g. Jacobs and Buechley (2013) [9]argue that “Art and design are two domains that offer exciting possibilities when combined with programming and digital fabrication. Unfortunately, use of programming as a medium for art and design, especially by young adults and amateurs, is limited. [..] Despite this perception, programming has the potential to correspond well with traditional, physical art-making practices [7]. By finding ways to connect computation to the design and production of personally relevant physical objects, it is possible to engage novice practitioners in creative programming. The combination of digital-fabrication technologies with computational design serves as one such connection.”. In this paper, the authors identified the following main outcomes of a a ten-day computational fashion workshop: “The combination of computational design and fabrication can actively support the expression of personal identity in a positive setting. It can also foster feelings of confidence in programming and support aesthetic and technological literacy. The projects from the workshops demonstrate unique aesthetics and suggest new opportunities for casual and novice practitioners of art, craft, and design. The workshops also promoted a deep understanding of computation as evidenced by critiques of the participants as well as demonstrating the importance of physical prototypes in the design process. Finally, the workshops promoted a sustained engagement in programming”.
