O impacto do uso da experimentação e das tecnologias digitais de informação e comunicação na perspectiva investigativa na formação dos conceitos de ácidos e bases para estudantes do ensino fundamental

Abstract

This research presents a proposal of the Sequences of Teaching by Investigation (SEI) about the formation of concepts of acids and bases from experimentation and use of Digital Technologies of Information and Communication (TDIC) in Science Teaching (EC) for Elementary School students. It has as a problem and research guide the following question: How the use of experimentation and TDIC can contribute to the concept formation of acids and bases to Elementary School students? This research aims to build and analyze a Sequence of Teaching by Investigation (SEI) about the concepts formation of acids and bases to Elementary School students using the experimentation and TDIC. The SEI, developed in this research, was based on the use of open laboratory and technological resources. With the involvement of 16 students from 9th grade of Elementary School, this work was carried out in a state public school, in the city of Curitiba, Paraná. This qualitative research is characterized by being interventional. The corpus of research consists of recording and transcription of students’ speeches, photos and field diary registration, questionnaire, roundtable, experimental activities and using a simulator. To analyze data, it was used the Discursive Text Analysis (ATD), which allows the researcher to interpret their perspectives and assume possible results. From the analysis of the answers proposed to the students, five categories emerged: 1) Science teaching and scientific investigations, 2) process of formation of the acids and bases concepts, 3) biosafety control, 4) raising of hypotheses, 5) students’ engagement, showing that research is done with investigation, hypotheses raised, discussions, data analysis and experiments. The goals were achieved, from the application of SEI, following the precepts of Teaching by Investigation, to bibliographic surveys that brought to the research the analysis of schoolbooks directed to the Science Teaching and the referrals of TDIC and experimental activities, as well as the possibilities of applying the Teaching by Investigation. After applying and pointing the results and discussions related to Sequences of Teaching by Investigation, it was developed as Education Product, a teaching support material with methodological guidelines to the teaching of acids and bases in Elementary School.
