Resumo(s)
A Direção-Geral de Estatísticas da Educação e Ciência (DGEEC) tem armazenado uma
vasta quantidade de dados sobre os alunos que frequentaram o sistema de ensino Português
através de inquéritos preenchidos pelos alunos e colecionados a partir das instituições de
ensino.
O objetivo deste projeto foi produzir visualizações que permitam estudar o fluxo
dos estudantes que frequentaram o sistema de ensino nacional nos últimos anos. Este
trabalho está integrado no projeto ModEst (Modelação do fluxo de estudantes no sistema
de ensino Português), que tem como objetivo minerar os dados da DGEEC de modo a
obter modelos setoriais do sistema educacional bem como um modelo global que seja útil
para a definição de políticas organizativas do sistema de educação e para tomar medidas
específicas corretivas.
Desenvolveu-se uma aplicação web que oferece um conjunto de visualizações interativas que permitem a exploração dos dados agregados do fluxo da população estudantil,
fornecidos pela DGEEC. Foi dada uma importância acrescida ao uso de tecnologias
open-source para o desenvolvimento desta aplicação.
Neste trabalho apresentam-se as várias abordagens à visualização de dados de fluxos e
tecnologias dentro do ecossistema das ferramentas, frameworks e bibliotecas open-source
para a criação de visualizações interativas para a web. Também se relata o desenvolvimento
da aplicação web que servirá para explorar interativamente os dados trabalhados do
ModEst, nomeadamente as escolhas das tecnologias e os desafios encontrados durante o
desenvolvimento. A aplicação desenvolvida foi testada por peritos da DGEEC para avaliar
a usabilidade da solução final.
DGEEC (the National Office of Education and Science Statistics) has gathered a vast amount of data about students who attend the national education system through surveys and forms that are handed to students and schools. This project’s goal was to create visualizations that aid the study of the flow of students that frequented the national education system in the last years. This work was part of the ModEst project (Portuguese Education System Student Flow Modeling), whose goal was to mine DGEEC data in order to obtain sectorial models of the educational system, as well as to generate a global model that is useful for the government to define organizational policies and to take specific corrective measures. A web app was developed. This web app offers a set of interactive visualizations that allow the exploration of segmented data about the flow of the student population, provided by DGEEC. There was a heightened importance in the choice of open-source technology for the development of this app. This work presents some approaches to visualizing flow data and technologies within the open-source ecosystem, frameworks and libraries for creating interactive visualizations for the web. Also reported is the development of the web application that will serve to interactively explore the data provided by ModEst, namely the choice of technology and the challenges encountered during development. The final application was tested by DGEEC experts to evaluate its usability.
