چکیده

پیشینه و اهداف: محتوای علمی برای مبحث اصل لوشاتلیه و عوامل موثر بر تعادل‌های شیمیایی مبتنی بر رویکرد زمینه‌محور طراحی شد. مخاطب این محتوا، دبیران محترم شیمی می‌باشند. روش‌ها‌: پژوهش حاضر از نوع کاربردی-توصیفی است. ابتدا مقاله‌ها، کتاب‌های علمی و سایت‌های معتبر علمی مرتبط با آموزش اصل لوشاتلیه و تعادل‌های شیمیایی بررسی شدند. حاصل مطالعه اولیه جمع‌آوری پیش‌نیازها و دسته‌بندی آن‌ها بود. سپس، کمبودهای مطالب کنونی در کتب درسی، بدفهمی‌های موجود در آموزش و همچنین علت ایجاد این بدفهمی‌ها و کج‌فهمی‌ها، مورد بررسی قرار گرفتند. سپس، عناوین مناسب برای طراحی محتوا، حاوی فعالیت‌های متعدد، تعیین گردیدند. در ادامه، جدول هدف-محتوا طراحی و پس از ارزیابی توسط اساتید و دبیران باتجربه و خبره، نهایی شد. یافته‌ها: در نهایت، محتوا طراحی شد و توسط اساتید متخصص شیمی، مورد بررسی و ارزیابی قرار گرفت و متناسب با نظرات ایشان، بازبینی لازم صورت گرفت. متخصصان ارزیاب، محتوای طراحی شده با رویکرد زمینه‌محور را برای موضوع مذکور تایید نمودند. نتیجه‌گیری: با توجه به تاثیر رویکرد زمینه‌محور در تعمیق یادگیری، آموزش و کاربرد این روش برای معلمان و دانشجومعلمان توصیه می‌شود. با در نظر گرفتن رویکرد زمینه‌محوری در آموزش کتاب‌های درسی، از جمله آموزش علوم، شایسته است تاثیر این رویکرد در آموزش و یادگیری این دروس، مورد توجه پژوهشگران قرار گیرد.

چکیده [English]

In this research, scientific content was designed to address Le Châtelier’s principle and factors affecting chemical equilibrium based on the context-oriented approach. The audience of this content is chemistry teachers all over the country. The type of this research is applied-descriptive. In the first stage, articles, scientific books, and reliable scientific sites related to teaching Le Châtelier’s principle and chemical equilibriums were studied. The result of the initial study was the collection of the required prerequisites and the classification of the collected materials. The lack of current content in textbooks, existing misunderstandings in education, and the cause of these misunderstandings and misconceptions were investigated. Then, suitable titles for content design containing multiple activities were determined. Afterthought, the goal-content table was designed and finalized after evaluation by experienced and expert professors and teachers. Finally, the content was designed, reviewed, and evaluated by expert chemistry professors, and necessary revisions were made according to their opinions. The evaluator experts approved the designed context-based content for the mentioned topic. Considering the impact of the context-based approach in deepening learning, the teaching and application of this method is recommended for teachers and student teachers. Considering the context-based approach in teaching textbooks, including science education, researchers should pay attention to the impact of this approach in teaching and learning these subjects.
