SCIENTIFIC AND TECHNICOLOGICAL DIFFUSION IN THE BASIC EDUCATION WITH EMPHASIS ON NANOSCIENCE AND NANOTECHNOLOGY: A DESIGN-BASED RESEARCH ANALYSIS

Abstract

In this paper, the description and the analysis of stages concerning the Design-Based Research (DBR) employed on a proposal for scientific and technological diffusion concerning the fields of Nanoscience and Nanotechnology in the Basic Education are discussed. To that aim, as an artifact, an Interdisciplinary Didactic Sequence (IDS), which drew upon graphene and other allotropic forms of carbon to approach physics and chemistry topics in the high school, was brought out. Interventions in the classroom took place in May, in 2021, and right after the redesign, in June, in 2022 - both organized in groups of fifteen students from the Military School of Santa Maria (Colégio Militar de Santa Maria - CMSM). Diverse assessments after the second intervention indicated, through questionnaires and argumentative-discursive texts, that 73% of the students participating in the research obtained very satisfactory performance. However, through conceptual maps, only 26% of the students had an unsatisfactory performance in their construction. These results demonstrated evidence of significant learning, validating the artifact and suggesting effectiveness of the process.
