O ensino de radioatividade por meio de uma UEPS intercedida pelas tecnologias digitais

Abstract

With the advent of the new millennium, the use of digital technologies, increasingly present in human daily life, has driven profound cultural changes in contemporary society. Technological advances that are updated almost daily have not reached educational institutions with the same agility. In this sense, traditional teaching has become unattractive to students, and it is up to teachers to insert digital technologies into their teaching practice as a learning enhancer, transforming these tools into allies in the teaching-learning process. From this perspective, it is understood that it is possible to develop Chemistry teaching in a very current and contextualized context, making it more attractive and promoting student protagonism. Thus, this research was guided by the following question: What are the contributions of a Potentially Significant Teaching Unit, associated with and mediated by digital technologies, in the teaching of radioactivity in High School? To assess the relevance of the UEPS, a study was developed based on qualitative research, seeking to analyze data collection instruments such as: "logbook", activities and materials developed by students during the implementation of the didactic proposal. Elements that could demonstrate cognitive progress with signs of significant learning were sought. The implementation of the proposal for the application of the educational product was developed with second-year high school students on the premises of the Plácido de Castro State Elementary and High School, located in the city of Jaru, State of Rondônia. The implementation of this UEPS required 15 hours/classes structured in three weekly meetings. The results showed that the study of systematized radioactivity, in the form of UEPS, mediated by ICTs, proved to be a good teaching approach, providing students with meaningful learning, making classes more participatory and engaging. The present UEPS, which is the educational product linked to this master's dissertation, was developed in order to provide the Chemistry teacher of Basic Education with resources that can help him promote a more meaningful, well-structured teaching-learning, presented as a compilation of activities focused on ICTs, since in the current moment of education, there is an indisputable need for discussions that explore methodologies that relate school teaching to the reality experienced by the student. The educational product entitled "Radioactivity, a UEPS interceded by digital technologies" is freely available on the program's website, on the PPGECM educational products portal and on the EduCapes portal at http://educapes.capes.gov.br/handle/capes/742419.
