Isolating such concepts in courses helps students not only to focus on specific aspects, but also to experience the reality of working with modern computer systems, where those concepts are often detached in different abstraction levels. However, due to such an isolation, it exists a risk of inducing to the students an absence of interactions between these concepts, and, by extension, between the different abstraction levels of a system. This paper proposes a learning experience showcasing the interactions between abstraction levels addressed in laboratory sessions of different courses. The driving example is a parallel ray tracer. In the different courses, students implement and assemble components of this application from the algorithmic level of the tracer to the assembly instructions required to guarantee atomicity. Each lab focuses on a single abstraction level, but shows students the interactions with the rest of the levels. Technical results and student learning outcomes through the analysis of surveys validate the proposed experience and confirm the students learning improvement with a more integrated view of the system. info:eu-repo/grantAgreement/ES/DGA-ESF/T58-20R info:eu-repo/grantAgreement/ES/DGA-FEDER/Construyendo Europa desde Aragón info:eu-repo/grantAgreement/ES/DGA/T21-20R-DISCO info:eu-repo/grantAgreement/EC/H2020/682080/EU/Intuitive editing of visual appearance from real-world datasets/CHAMELEON This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 682080-CHAMELEON info:eu-repo/grantAgreement/ES/MICINN/PID2019-105004GB-I00 info:eu-repo/grantAgreement/ES/MINECO-AEI-ERDF/PID2019-105660RB-C21 info:eu-repo/grantAgreement/ES/MINECO/TIN2017-84796-C2-2-R info:eu-repo/grantAgreement/ES/UZ/PIIDUZ-18-246 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.542 2021 COMPUTER SCIENCE, THEORY & METHODS 18 / 110 = 0.164 2021 Q1 T1 1.289 2021 Artificial Intelligence 2021 Q1 Theoretical Computer Science 2021 Q1 Software 2021 Q1 Computer Networks and Communications 2021 Q1 9.2 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Gran-Tejero, Rubén Universidad de Zaragoza (orcid)0000-0002-4031-5651 Suárez-Gracia, Darío Universidad de Zaragoza (orcid)0000-0002-7490-4067 Georgescu, Emanue A.
