DESCRIPTION OF THE TASKS

Pre-task: Before starting the activity, students will receive a brief contextualization of the story: a mysterious crime has occurred, and Arnau has been found dead.  The students have to take on the role of investigators and work to find out what went wrong.  They will read the case's introduction, learn about potential suspects, and familiarise themselves with the game's setting during this initial phase.  Activating prior knowledge, igniting curiosity, and preparing them for the challenge ahead are the objectives of the pre-task.

Main activity:  Students will access an interactive Thinglink during the main activity, where they will discover various locations and case-related items.  They will investigate the pictures, access interactive elements, gather hints, examine testimonials, and interpret hidden messages by following the given instructions.  They will get closer to cracking the case with each hint.  Students will collaborate to identify Arnau's killer by exchanging theories, analysing the data they find, and applying logic.

After-task: After the investigation is over, each group will present their findings and provide an explanation of how they identified the offender. Students will be urged to reflect on the process in this last phase, taking into account their teamwork, information-gathering techniques, and capacity to defend their conclusions. Lastly, the case's solution will be disclosed, and the activity's main learning objectives will be covered.
