瞥见分数,几家欢喜几家愁。由100分退为98分的孩子,经历亲吻到耳光的奖惩;由55分进步为61分的孩子,感受的则是耳光到亲吻的悲喜。这幅场景,使人会心一笑之余,不由得深思:正常的成绩波动,何以如此强烈地牵动爸妈的情绪?
究其奖惩差别的原因,不过是退步的“好孩子”没有取得满分,而“差孩子”完成了由不及格到及格的飞越。简言之,退步意味着惩罚,进步会换来奖励,对宏观视角下孩子所表现出的稳定水准,爸妈们似乎并未予以考虑。然而,一切教育都是从我们对儿童天性的理解开始,家庭教育在孩童启蒙中的地位尤其无可撼动。如此简单干脆的处理,影响的,岂止孩子稚嫩的脸颊?
今昔求索,这样的案件比比皆是。聚焦新闻,被誉为“东方神童”的魏永康,其母得知他被中科院劝退的消息时,歇斯底里着让他“去死”,却忽略毫无自理能力儿子的内心隐痛;放眼四海,一场考试完结后,多少“进步了重重有奖”的诺言正等待兑现?忽忆起马克·兰博教授的“过度理由效应”:金钱等物质奖励的外在动机,会削弱对活动本身的享受和对满足感的关心。
再将目光转回那两名为成绩左右的孩童,虽不可危言耸听断言他们的未来将拘泥于“蜗角虚名,蝇头微利,算来着甚干忙”的世俗,但在下一场测验中,恐怕除了试题,他们也会投注几分心思在对“糖果”的期待和对“棍棒”的惶恐上。由此推之,岂独两小儿哉?是否千千万万稚子,都不能意识到考试本身“查漏补缺”的效用,而是专注于脑海中爸妈时嗔时悦的脸色,紧张于罅漏中的奖惩?一声长叹。
无论如何,看见孩子无邪天真的笑颜是所有人的心愿,“让孩子拥有快乐童年”的号召亦是无可非议。静言思之,这并非不切实际的虚幻畅想,而是触手可为的动人之举。当面对孩子成绩的55到61,或100至98时,应以“流水不腐,户枢不蠹”的旷达淡然置之。“童子者,人之初也;童心者,心之初也。”李贽绝假纯真的《童心说》中坦率表露了对孩童的欣羡和维护赤子之心的呐喊。而作为家庭教育的施予方,爸妈们可否宠辱不惊,以良好的心态处理望子成才与循序渐进的理性平衡?衷心希望,进步也好,退步也罢,都能看到孩子脸上如花的明艳!
