TITLE:

CHEMISTRY IN THE GARDEN AS A PROPOSAL FOR AN INTERDISCIPLINARY APPROACH IN ELEMENTARY EDUCATION.

KEY WORDS:

Nature of Chemistry; chemistry education; epistemology; ideal gases

SUMMARY:

Research in Chemistry Education has indicated that the didactic incorporation of aspects related to the Nature of Chemistry can foster deeper student reflection on chemical explanations, the epistemological status of scientific models, and the processes involved in the construction of scientific laws, among other issues. From this perspective, such approaches have the potential to support both teaching and learning in basic education. This study presents an investigation that explores these aspects through a didactic proposal focused on the topic of ideal gases, integrating historical–epistemological discussions, model construction, and experimental activities. The research was conducted within the context of a teaching sequence implemented with 28 first-year high school students from a private school in the city of Natal, Rio Grande do Norte, Brazil. The sequence included diagnostic questionnaires, the production of graphical representations, experimental activities mediated by the Predict–Observe–Explain (POE) strategy, collective discussions, and the development of infographics. Data analysis was conducted through Discursive Textual Analysis (DTA), in dialogue with theoretical contributions from the field of philosophy of chemistry. The results indicate that the teaching sequence fostered the mobilization of more elaborated meanings among students regarding the behavior of gases and the nature of chemical knowledge. The analyzed productions reveal an articulation between experimental observation, the use of scientific models, and an understanding of the historical and provisional character of scientific explanations. Within the context of the investigated experience, the findings also suggest that an approach grounded in the Nature of Chemistry, articulated with the teaching of gases, may create favorable conditions for the explicit expression and reorganization of meanings mobilized by students, pointing to possibilities for promoting a more reflective understanding of chemical knowledge.
