كتبت شروق عارف
في ظل التطور التكنولوجي الحادث والابتكارات الجديدة ظهر العالم الافتراضي الذي أحدث ثورة في كافة المجالات مما جعلنا نطرح سؤال مهم ماذا لو أصبح التعليم مرتبط بالعالم الافتراضي؟ وكيف سيؤثر هذا الربط على الطلاب وتحصيلهم الأكاديمي ؟ ما هو العالم الافتراضي والميتافيرس؟ مزايا وتحديات ربط التعليم بالعالم الافتراضي
آراء متباينة حول فاعلية العالم الافتراضي
يمكن القول إن ربط التعليم بالعالم الافتراضي قد يسهم بشكل كبير في توسيع أفاقنا الفكرية وسوف يجعل التجربة التعليمية أكثر متعة ولكن مع ذلك يجب التعامل مع هذه التقنية بحذر حتى نتجنب الأثار السلبية وعلينا التأكد أن العالم الافتراضي لا يمكن أن يحلل محل المعلم
