Abstract
We conduct an RCT in Italian high schools with different mayors, and we randomize access to digital skill courses. Courses are taken by students for credit, they are standard in format and employ a tested learn-by-doing pedagogical approach, and cover 3D design, 3D printing, and laser cutting: these content in Italy are typically covered by selected STEM courses at the university level. We test whether participation fosters interest in STEM subjects for future university studies, relative occupations, creativity and grit, in separate manuscripts. In particular, we are interested in detecting gender differences in the effect of treatment. The ever-growing demand on the job market for digital skills and STEM degrees makes them important components of pre-university education. However, especially in countries with education systems dominated by humanistic subjects, school curricula fail to include scientific and quantitative subjects to a sufficient degree, and under-expose students to the use of technology, leading to sub-optimal demand for STEM degrees at the university level. This is particularly true for girls, as they tend to engage less with STEM-related education at school even when it is offered, and thus self-select into non-STEM subjects at university (OECD, 2020).

Experimental Design

Experimental Design
Two experimental groups:

T: Students are offered access to digital skills courses, which are valid for school credit requirements. Courses cover 3D design, 3D printing, laser cutting. Course format can be of 3 different types: long (~20 hrs), short (~10 hrs), hackaton (course + competition): however for institutional constraints, access to different types of treatment is not randomized. For more details, see the attached Pre-Analysis Plan.

C: Students are only offered access to other activities, unrelated to digital skills covered by treatment courses. These placebo activities are observed.

Abstract
Creativity and grit are widely recognized as vital components for the success and prosperity of individuals, even more so for younger people who will have to deal with the complex challenges connected to the digital era. Yet, whether these skills can be learnt or are innate traits is still subject to debate, which is further complicated by the difficulty of defining and, in turn, assessing these concepts. In this study, we challenge the idea that creativity and grit cannot be learnt and show that creative pedagogy activities, such as those offered by FabLabs, are powerful tools to enhance these non-cognitive skills. We conduct a randomized controlled trial in which 710 students from five Italian high schools are randomly assigned to creative STEM courses. The courses are delivered by FabLabs, small-scale workshops that offer access to tools for digital fabrication and employ a hands-on pedagogical approach expected to impact students’ creativity and grit positively. Assignment to the courses is at the class level: only students in classes randomly selected to join the Fablab activities can participate, and they may decide whether to enrol or not on a voluntary basis. We address noncompliance by adopting an instrumental variable approach. We use two modalities to measure creativity: a self-assessment through the Short Scale of Creative Self and an assessment made by an independent expert using an index of creativity developed by the authors. While the effect on self-assessed creativity is not significant, results show that the external, independent assessment of students’ creativity can capture a significant effect of Fablabs’ courses. It also emerges that FabLab activities have a positive significant effect on students’ grit, measured through the Duckworth scale. The encouraging results obtained for a relatively small sample of students should prompt a replication of the experiment on a broader scale.
