الواجب الدراسي TMA
التربية الفنية الخاصة SP111

الفصل الدراسي الأول للعام الأكاديمي 2013-2014م

موضوعات الواجب

الموضوع الأول : (10 درجات)
لدراسة الفروق الفردية في مجال التعبير الفني أهمية كبيرة، باعتبار أن لكل طفل حاجاته التربوية الخاصة التي يختلف فيها عن بقية أقرانه. وتمدنا دراسة الفروق الفردية في مجالات التعبير الفني بالأساس العلمي الذي يمكن أن يبني عليه المعلم عمله وتوجيهاته لتلاميذه داخل الفصول الدراسية، وقاعات النشاط المدرسي. في مقالة من عشر صفحات تناول موضوع الفروق الفردية في مجال التعبير الفني من حيث ما يلي:
1. الفروق بين رسوم الأطفال من الجنسين.
2. الفروق بين رسوم الأطفال الصم وأقرانهم العاديين.

لموضوع الثاني : (10 درجات)
كما تساعدنا الرسوم المقننة والحرة في تشخيص الصعوبات ومظاهر الاضطرابات التي يعاني منها الأطفال والمراهقون والكبار على السواء، ومعرفة جذورها الدينامية، فإن للتعبير الفني والرسوم خصوصا تأثيرا علاجيا، ووظائف بنائية لها دورها الفعًال في استعادة التوازن الانفعالي والتوافق الشخصي والاجتماعي للفرد والحفاظ على صحته النفسية. في مقالة من عشر صفحات تحدث بالتفصيل عن رسوم الأطفال العاديين وغير العاديين كوسيلة علاجية.
