INTROSEQ: A MOBIL DIGITAL LEARNING OBJECT FOR NUMERICAL SEQUENCES TEACHING
Digital Learning Objects. Numerical Sequences Teaching. Smartphones. INTROSEQ application.
The research general aim was to develop and evaluate a Digital Learning Object (DLO) about Numerical Sequences for Android and IOS smartphones. In order to reach our aim we try to know how the Digital Learning Object/Application INTROSEQ uses, possibilities and limitations may contribute in Numerical Sequences Teaching for high school first grader. We introduce our theorical aspects for Numerical Sequences Teaching based on Brazilian curricular documents, mainly those studied in BNCC. We also brougth up discussions based on curriculum researches and Digital Learning Objects with its uses in smartphones as well as its evaluations. To develop INTROSEQ application we use Design Methodology studied in Lobäch’s Methodology and observed in his 4 design phases. We brougth up a qualitative approach in our DLO evaluation using data triangulation in the last phase of Lobäch’s Model and adopting the Teaching Experiment as a methodological procedure. Five mathematics teachers from Tangará da Serra, state o Mato Grosso participated via Google Meet platform to do the former procedure. The instruments for data production were a research form, semi-structured and structured questionnaires, audiovisual records and observations during the Experiment Teaching. The research results sugest that the DLO/Application INTROSEQ potentialities meet the user approach and might be used in the Numerical Sequences Teaching whith some restrictions when its functionalities depends on the internet.
