The e-Lite research group will partecipate at the 42th IEEE International Conference on Computers, Software, and Applications (COMPSAC 2018), to be held in Tokyo (Japan), from the 23th to the 27th of July 2018. The conference, organized by the IEEE Computer Society, focuses on different aspects of computer science and engineering and it is organized in 10 symposia, ranging from Computing Education to Software Engineering, to Computer Architecture and Data Science.

Laura Farinetti will present a paper entitled "Improving the Effectiveness of SQL Learning Practice: A Data-driven Approach", during the first session of the Computing Education and Learning Technology (CELT) symposium, on July 26 at 11:00. The paper presents a learning environment to improve the experience of both students and teaching assistants during SQL labs. An application, designed to support the learning environment, stores all the events occurring during a SQL practice lab, i.e., task progression, query submissions, error feedback, assistance requests and interventions, and it provides information useful both for use on-the-fly and for later analysis. Thanks to the analysis of these data, the application dynamically provides teaching assistants with a graphical interface highlighting where assistance is most needed, by considering different factors such as the progression rate, the percentage of correct solutions, and the difficulties in solving the current exercise. Furthermore, the stored data allow teachers later on to analyze and to interpret the behavior of the students during the lab, and to have insights on their main mistakes and misconceptions. After describing the environment, the interfaces, and the approaches used to identify the students' teams that need timely assistance, the paper presents the results of different analyses performed using the collected data, to help the teacher better understand students' educational needs.

The conference joined a new IEEE program, named Open Preview, which allows conference proceedings to be available in the IEEE Xplore digital library, free of charge to all, one month before the conference until the conference ends. Therefore, the paper can be read free of charge (up to the 27th of July) at:
