    第十周国旗下讲话—发展艺术教育提高审美情趣

    尊敬的学校领导、老师,亲爱的同学们:大家早上好!今天我讲话的题目是“发展艺术教育提高审美情趣”。近期不少教育界、学术界的有识之士呼吁,国民艺术教育应该成为人们关注的一个社会问题。这里所说的艺术教育,不同于培养专门艺术人才的专业教育,而是指提高同学们的文化修养、鉴赏能力、审美情趣。艺术素质教育的目的集中在人格的培养上。注重培养智力为知的素质,气质为情的素质,性格为意的素质,能力为技的素质是我们追求的目标。艺术教育是渗透性教育即在语文、 数学、英语等学科教学中渗透艺术教育。它对于陶冶人们的思想情操,提高人的审美情趣,使人树立崇高的审美理想,具有其它教育所不可替代的作用。拿艺术教育中的美术教育来说,它是通过各种教学实践活动,使同学们在直接感受中了解、认识美,在感知中理解鉴赏美,在感悟中体现和创造美,从而达到较深刻的审美意识。鲁迅先生曾指出:“美术可以辅翼道德,美术之目的,虽与道德不尽符,然其力足以渊邃人之性情,崇高人之好尚,亦可辅道德以为治。”由此可见,美术能陶冶人的情操,净化人的心灵,丰富人的感情,让人们心身健康地发展,培养人的高尚品德和审美意识,使人树立正确的人生观……
