Opinion of the jury

Opinion by: Joan Melià

Commentary: The project aims to explain the serious impact of the pandemic in a city like Barcelona, where the economy is strongly focused on tourism and trade, based on information that can be extracted from open data.

Highlight: A clear methodology has been followed, specifying in detail the data used to analyze a topical issue and impact such as the effect of Covid-19 in the city of Barcelona. Also noteworthy is the socio-economic view based on the analysis of different indicators (correlating data) to better illustrate the effect of the pandemic on the most vulnerable people. Finally, the team has objectively identified (based on data) possible solutions, but caution should be commended when recommending them due to the current context of the pandemic.

Proposal for improvement/continuity: Although the use of datasets with sex-differentiated information is specified, it does not end up moving to work, and this could have provided interesting details. In a more formal aspect, the different media (memory, video, infographics and graphics) include different data or visualizations, which creates some confusion when it comes to understanding what details have been worked on in the project.

2nd Prize: Institut Vila de Gràcia

Project: L'impacte de la pandèmia a la vida quotidiana
Author/s: Etna Godàs, Tiruedil Robles, Irina Marsà, Màssimo Pino i Laia Duret
Tutor: Laura Conti and Reyes Peiró
Grade: 4th ESO

Opinion of the jury

Opinion by: Oleguer Sagarra

Commentary: It is a work with a good approach, a good choice of datasets to analyze and a good process both analytical and interpretive as well as methodological. The choice to make a comparative analysis between two periods of time is right and illustrates the phenomenon to be studied.

Highlight: This is a work where both the choice of datasets and the methodology, as well as the rhythm, the performance and the staging of the presentation stand out. Good work has been done and the analysis is consistent.

Proposal for improvement/continuity: Work has two important limitations. On the one hand, and especially the memory, which is not self-contained (the graphs are not shown), nor is it developed by exploiting the full potential of the work done. A critical analysis of the work and tangible proposals for improvement is especially lacking. On the other hand, the graphics in the infographic are very unreadable, which partially hides the good work done with data collection and interpretation.

3rd Prize: Institut Josep Comas i Solà

Project: Qualitat de l’aire i COVID-19: el confinament ha fet de Barcelona una ciutat menys contaminada?
Author/s: 3rd ESO. Groups A and B (36 students)
Tutor: Eva Gorrochategui
Grade: 3rd ESO

Opinion of the jury

Opinion by: Enric Rubio

Commentary: The aim of this work is well defined and represents a topical contribution. The result of the analysis that has been developed in this work regarding the relationship between human mobility and the concentration of nitrogen dioxide (pollution), shows how important it is to work to try to reduce the levels of NO2 derived of mobility.

Highlight: Data processing is one of the main elements of this work, where different tools have been used to represent the data. Infographics also represent an element of special attention, where the narrative clearly presents the objectives, data analysis, and conclusions.

Proposal for improvement/continuity: The report does not go into detail of the methods of analysis used. No fluid visual language of interaction with the audience is observed in the presentation, nor do the speakers maintain eye contact with it.


Institut Doctor Puigvert

Project: Quin barri de Barcelona té la millor qualitat sanitària pública?
Author/s: Firdaous Bendris, Valentina de Sousa, Sohaib El Anaya, Laura Las Heras
Tutor: Oriol Ventura
Grade: 1st Year of High School

Opinion of the jury

Opinion by: Laia Albors

Commentary: The objective of this work is well defined and represents an innovative and current contribution: considering differentiating the city's neighborhoods based on available health resources and demographic data is, in fact, relevant and significant information for anyone who decides Live in the city. They have known how to choose the data correctly and the analysis methodology is clearly explained and is adequate to achieve the objectives set.

Highlight: From this work, it is worth highlighting the treatment that has been made of the data, where it becomes clear that data analysis is not only about making graphs, it is also necessary to make calculations to derive the information that is most relevant. For example, in this project, the fact that the data have been scaled and normalized instead of using absolute values, has allowed them to establish a correct comparison between neighborhoods, thus achieving the objective set.

Proposal for improvement/continuity: A small shortcoming found in the work is that the missing values have not been treated in the best way, directly affecting the representativeness of the calculated health quality index. Although the work is very correct, if we wanted to continue working in this line, an idea for improvement would be to consider other variables that would inform us about the levels of health stress in each area.

Institut Joan Fuster

Project: L'educació a Barcelona
Author/s: Jan Mata, Amin Kabbani
Tutors: Montserrat Perela y Melisa Dipacce
Grade: 3rd ESO

Opinion of the jury

Opinion by: Jordi Vitrià

Commentary: The aim of the work is interesting and always current: the state of education in Barcelona based on open data. The analysis of the data has revealed complex imbalances regarding the presence of girls and boys at different educational levels and also a biased distribution of schools to private individuals. The work has also analyzed youth unemployment, which can be seen as a factor highly dependent on education among young people. In this aspect, a gender bias is also detected that favors boys over girls.

Highlight: Although the topic is very broad, the aspect that has most interested students has been the gender bias present in the education data in Barcelona. From this point of view, the analysis of the data has allowed the students to realize on their own a very close social problem and to raise a good paradox: How is it that having the girls a slightly higher level of training they suffer a level of unemployment also slightly higher?

Proposal for improvement/continuity: Students have perfectly identified the limitations presented by the data and also what additional information, especially related to a better granularity of the information, would have allowed them to reach more detailed conclusions about the observed phenomenon.

Opinion of the jury

Opinion by: Helena Ramalinho

Commentary: The subject of the work is interesting and also original, I think it is very relevant that the students are interested in their neighborhood and its buildings.

Highlight: The infographic adequately shows the work done and the main conclusions of the project. The presentation is easy to follow and demonstrates the teamwork done.

Proposal for improvement/continuity: The report presents the basic aspects, but it could have been extended by explaining in more detail the methodology and data used, the possible improvements and main conclusions of the project.
