ARGUMENTATION IN CHEMISTRY CLASSES: TEACHING STRATEGIES IN THE SPOTLIGHT

Research in the area of science teaching has highlighted the importance of using argumentation in the classroom, as well as preparing teachers to undertake and conduct activities of this nature. In order to bring elements that contribute to the progress of discussions about the subject, we investigated implementing and developing two teaching strategies (ludic activities and chemistry experiments) in lessons taught by pre-service teachers in supervised internships and we identified their pro-argumentation actions. The results showed that pre-service teachers not fully achieved the task of promoting argumentation practices in chemistry classes, emphasizing their ease and difficulties throughout the activity.

科学教学领域的相关研究已然凸显了课堂中开展论证式教学的重要价值，同时强调了培养教师胜任并实施此类教学活动的必要性。为提供有助于推动该主题研讨的相关支撑材料，本研究针对参与带教实习的职前教师所开展的课堂教学，对两种教学策略——游戏化活动与化学实验——的实施与开发情况展开了调研，并识别了其教学过程中展现的支持论证行为。研究结果显示，职前教师未能完全达成在化学课堂中推广论证教学实践的任务，同时也凸显了其在本次活动全程中所具备的实施优势与面临的现实困境。
