چکیده

هدف از انجام این پژوهش، آموزش شیمی سبز مبتنی بر برنامه درسی آزمایشگاه شیمی عمومی1 طراحی شده با این اصول و بررسی تاثیر فعالیت عملی بر میزانیادگیری و نگرش دانشجومعلمان نسبت به اصول شیمی سبز می‌باشد. دوره آموزشی شامل دو آزمایش در آزمایشگاه شیمی عمومی 1 بر مبنای  اصول شیمی سبز می‌باشد. این آزمایش‌ها عبارتند از تعیین رابطه جرمی مولی در یک واکنش شیمیایی و تعیین میزان آسکوربیک اسید موجود در قرص ویتامین C. روش پژوهش از نوع کاربردی، آزمایشی و نیمه تجربی بوده و ابزارهای مورد استفاده، آزمون‌های محقق ساخته درحیطه یادگیری و آزمون نگرش سنج شیمی سبز بوده است. نمونه پژوهش، شامل گروه آزمون (30نفر) وکنترل (30نفر) ازدانشجومعلمان رشته شیمی در دانشگاه تربیت دبیر شهید رجائی تهران در سال تحصیلی 97-96می‌باشد که بصورت تصادفی چند مرحله‌ای انتخاب شدند. تجزیه تحلیل داده‌ها با استفاده از روشهای آمار توصیفی و استنباطی و با کمک نرم افزار SPSS انجام گرفته و نتایج بدست آمده بیانگر آن است که از بین 12اصول شیمی سبز، فراگیران اهداف مربوط به اصول 1تا 4 و 7تا12 رایادگرفته و مورد توجهشان قرارگرفته است، همچنین اجرای برنامه درسی مرتبط با اصول شیمی سبز علاوه بر یادگیری بر روی نگرش دانشجومعلمان شیمی نیز تاثیر مثبتی داشته است.

چکیده [English]

The purpose of this research is education of green chemistry through the curriculum related to the principles of green chemistry in General Chemistry Lab 1and the effect of this educational course on learning and attitude of the pre-service chemistry teachers toward green chemistry principles. This educational course involves two green experiments implemented according to green chemistry principles. The experiments include determination of molar mass relation in a chemical reaction and determination of the amount of ascorbic acid in a tablet of vitamin C. The research methods are practical, experimental and quasi-experimental and the used instruments were the researcher-constructed tests in the field of learning and attitude domain. Statistic population of this study consists of experimental group (N=30) and control group (N=30) of the student teachers at Shahid Rajaee Teacher Training University in the academic year 2017-2018. Data analysis was done using descriptive and inferential statistics with SPSS software. The obtained results show that among12 principles of Green Chemistry, students have learned the principles of 1 to 4 and 7 to 12 of these 12 principles and they have been attracted to them. In addition, the implementation of a curriculum related to the principles of green chemistry has had a positive impact on the attitude of the pre-service chemistry teachers.
