Tipologia de tarefas nos manuais escolares de Matemática: um estudo com manuais portugueses de 10.º e 11.º ano

The diversity of tasks is essential for learning considering the different functions they perform.Thus, it is important to provide students with the opportunity to have contact with different types of tasks in Mathematics.In this study, an analysis was made of all Portuguese manuals of 10th and 11th grade, which are authorized by the General Direction of Education for the academic year 2020/2021, of the subject of Mathematics A, in order to understand the diversity of tasks that manual proposed.These are two of the final three years of compulsory education in Portugal, inserted in the "Secondary Education", and students are usually between 15 and 17 years old.Considering that tasks can be divided into four main categories, according to its structure and its level of difficulty, it was concluded that about 88% have a closed structure and reduced level of challenge, approximately 11% also have a closed structure but a high level of challenge, and the remaining tasks have an open structure and reduced level of challenge, with a percentage below than 1%.As for open structure and high level of challenge tasks, only one was found.
