چکیده

هدف پژوهش حاضر، مقایسه ی فعالیت مغزی دانش آموزان دبیرستانی، در زمان آموزش نحوه ی عملکرد قلب، از طریق ویدئوهای کامپیوتری است. در یکی از ویدئوها تصاویر آموزشی دو بعدی و در ویدئوی دیگر تصاویر سه بعدی (15 تصویر) قابل رویت بود. این پژوهش به لحاظ دستکاری متغیر مستقل، نیمه آزمایشی محسوب می شود. در این پژوهش متغیر مستقل فعال بعد تصاویر ارائه شده و متغیر مستقل هویتی، هوش فضایی (بالا و پایین) دانش آموزان بود. جامعه ی مورد مطالعه کلیه ی دانش آموزان دبیرستانی رشته ی تجربی، شهرستان بردسکن اند که در سال تحصیلی 97-96 ثبت نام کرده اند. از این جامعه 50 نفر با هوش فضایی بالا و 50 نفر با هوش فضایی پایین (در هرگروه 25 نفر زن و 25 نفر مرد) به روش نمونه گیری خوشه ای انتخاب شدند. امواج مغزی دانش آموزان از طریق دستگاه EEG از نقاط مختلف مغز به دست آمد. داده های نهایی بعد از حذف نویز و آرتیفکت ها، با تکنیک تحلیل واریانس دو راهه تحلیل شدند. نتایج نشان داد که تفاوت معناداری در میزان فعالیت مغزی دانش آموزان با هوش فضایی بالا و پایین، وجود ندارد(p value>0.05). این موضوع در مورد سطوح مختلف ابعاد تصاویر (دو بعد و سه بعد) و همچنین تعامل هوش فضایی و ابعاد تصاویر صادق است. یافته های جانبی نشان می دهند که میزان فعالیت مغزی دانش آموزان وابسته به جنسیت است(p value<0.008)، از طرفی جنسیت با نوع تصاویر ارائه شده نیز تعامل معنادار دارد (p value<0.01).
