Realizado no âmbito da unidade Curricular Iniciação à Prática Profissional IV
do Mestrado em Ensino de Informática da Universidade de Lisboa, no Instituto de
Educação, este relatório documenta a experiência vivida na Prática de Ensino
Supervisionada (PES), realizada na Escola Secundária de Sacavém, do Agrupamento
de Escolas Eduardo Gageiro. Esta intervenção pedagógica foi realizada numa turma
do 1.º ano do Curso Profissional Técnico de Gestão e Programação de Sistemas
Informáticos, na disciplina Programação e Sistemas de Informação, em particular no
módulo 4 – Estruturas de Dados Estáticas.
Este módulo tem como temática principal as estruturas de dados estáticas na
linguagem programação C, propriamente os Arrays nos quais se inserem as variáveis
String. As atividades pedagógicas incidiram sobre os conceitos relacionados com a sua
definição e manipulação.
Considerando a natureza dos conteúdos, e a problemática associada a este nível
do ensino de programação, as atividades de aprendizagem planeadas foram
organizadas segundo os princípios da metodologia de Aprendizagem Baseada em
Problemas.
Assim, foram desenhados vários problemas que os alunos tiveram que
desenvolver para aplicar e dominar os respetivos conteúdos. Na primeira parte da PES
os exercícios foram realizados na IDE DEV C++, e na segunda parte o problema final
pretendeu que os alunos implementassem um sistema cujo funcionamento principal
consiste na visualização de Strings através de um display LCD modular ligado ao
Microcontrolador Arduino. Essas Strings apresentam valores de temperatura e
humidade ambiente captados através de um módulo dedicado também ligado ao
Arduino.
A análise dos resultados, relativa à evolução da aprendizagem dos alunos
apresenta uma melhoria nos vários domínios de avaliação sumativa, entre a primeira e
a segunda parte da PES, indicando também que esse fato esteve diretamente
relacionado com o aumento do grau de interesse e satisfação com a utilização da
plataforma Arduino nas atividades, assim como com a sua adequação à metodologia
PBL e respetivas estratégias.
Within the scope of the Initiation of the Professional Practice IV curricular unit of the Master’s degree in Informatics Teaching from the University of Lisbon, Institute of Education, this report describes the experience result from the Supervised Teaching Practice (STP), held at Sacavém High School, from the school group Eduardo Gageiro. This pedagogical intervention was realised in the 1st year class from the Professional Course of Computer Systems Management and Programming Technician, at the discipline of Programming and Information Systems, particularly in the Module 4 – Static Data structures. This module has as main theme the static data structures in the C programming language, properly the Arrays in which the String variables are inserted. The pedagogical activities focused on the concepts related to its definition and manipulation. Considering the nature of this theme contents, and the current issue ralated to teaching of this first programming level, the planned learning activities where organized and oriented by the Problem base learning methodology principles. Thus, several problems were designed that the students had to develop in order to apply and master the respective contents. In the first part of the STP, the exercises were carried out in IDE DEV C ++, and in the second part the final problem was that the students implemented a system whose main function is the visualization of Strings through a modular LCD display connected to the Arduino Microcontroller. These Strings present ambient temperature and humidity values captured through a dedicated module also connected to the Arduino. The analysis of the results, related to the evolution of the students' learning, shows an improvement in the several domains of summative assessment, between the first and the second part of the STP, also indicating that this fact was directly related to the increase in the degree of interest and satisfaction with the use of the Arduino platform in activities, as well as its adaptation to the PBL methodology and respective strategies.
