RESUMO:

Digital Learning Objects (DLOs) are present in the educational context, changing the way knowledge is constructed and transmitted. DLOs are an important tool to assist students in understanding concepts and chemical formulas, such as Chemical Equilibrium. Chemical Equilibrium is a fundamental topic in Chemistry education, involving the understanding of the relationship between the concentrations of reactants and products in a chemical reaction. DLOs, combined with Inquiry-Based Learning, can improve teaching by compensating for the lack of Chemistry laboratories in some schools. Given that Chemistry is a visual and experimental science, the use of DLOs in conjunction with Inquiry-Based Learning and a didactic sequence can contribute to the teaching of the content of Chemical Equilibrium, specifically the Ionic Equilibrium of water. The objective of this study is to understand the contributions of DLOs in teaching Chemical Equilibrium using the methodology of inquiry-based learning. The research method used was qualitative, employing a semi-structured interview guide, group discussions, and observations. The data was collected at "Deputado João Evaristo Curvo State School" in Jauru-MT, with the participants being 20 students from the 2nd year of high school, in the morning shift, who voluntarily participated in the study. An Investigative Didactic Sequence was developed, focusing on the theme "Chemical Equilibrium: Ionic Equilibrium in aqueous systems." The activities with the students, including planning, took approximately 30 hours. Data was collected using a semi-structured interview guide with open and closed questions, group discussions, and notes on the use of DLOs in the teaching of Chemical Equilibrium. The collected data was analyzed using an inductive method. In the inductive method, categories are created based on the units of analysis extracted from the data set. The researcher constantly compares and contrasts these units, organizing sets of similar elements based on prior knowledge. This inductive analysis process starts from specific examples to reach broader conclusions, resulting in emergent categories. The results showed that the use of DLOs, combined with Inquiry-Based Learning, provided a contribution to teaching Chemical Equilibrium. The students utilized the DLOs "Basic pH Scale" and "pH Scale" to visualize the pH of substances explored in the simulator. Through the Investigative Didactic Sequence, they were able to successfully complete the activities and provided positive feedback on the DLOs, improving their interest, learning, interaction among students, and especially their understanding of the content of Chemical Equilibrium, as observed in the interview guide. The practical investigative lesson, which involved an experiment with purple cabbage juice as a natural acid-base indicator mixed with other substances, allowed the students to perform a hands-on activity, promoting interaction among them. After mixing approximately 9 substances with the juice, they obtained different colors, each indicating the pH of the substance, from acidic to basic. They organized these containers and created a report, taking pictures with their cellphones and inserting them into the "pH Testing" DLO to obtain an approximate pH value. Their feedback was positive, as once again they were able to understand the pH of substances, a concept related to Chemical Equilibrium. In conclusion, the Investigative Didactic Sequence carried out with the DLOs was essential for the students to comprehend the content of Chemical Equilibrium. These investigative activities, simulators, and applications facilitated their teaching and learning process, even in the face of difficulties caused by the pandemic.
