  • Towards an Integrated Solution to Physical Assessment of Students
    Publication . Costa, Jason Philip Sardo; Fazendeiro, Paulo André Pais
    In this work, we propose a solution to support the student’s assessment process in physical education classes. Student’s accelerometry data performing several activities was collected using a smartphone and a developed mobile client. The collected accelerometry data is used for activity information extraction such as energy expenditure, number of steps and activity intensity. This information is displayed in a developed web application along with charts and student information. The main goal of this work is to develop a solution to complement the physical education class assessment process, by providing student’s activity information extracted from accelerometry data. This information is summarized and made readily available as a mean to aid and complement the teacher’s assessment process and grading system. By involving the students in the new class assessment system we also hope to motivate them to practice a more active lifestyle, providing them with visual information about their activity and allowing them to compare statistics between each other and, perhaps more important, evaluate their own evolution. The collected accelerometry dataset is made public to the community, as well as a free and open source mobile client for data collection. The performed experiments provided the necessary proof of concept to promote this solution as a valuable ally in the student assessment process in class. Moreover, these were essential to verify the actual practical value of the proposed assessment metric in a technologically heterogeneous physical education class environment. As a side effect a great set of information regarding student’s activity was produced. This dataset poses some hard challenges regarding activity identification and is made freely available to the machine learning community.
