However important we may regard school life to be, there is always the fact that children spend more time at home than in the classroom. Therefore, the teacher should realize that parents have a great influence on their children. Parents can become strong allies (助手) of the school or they can get in the way of the school education.

Experts have realized the need to keep parents informed of the newer methods used in schools. Many headmasters have conducted workshops explaining such matters as the reading readiness, program writing and mathematics to parents.

Moreover, the classroom teacher, with the permission of the supervisors(管理者), can also play an important part in giving more knowledge to reporting pupils progress, teachers can help parents a lot in educating their children and parents can give much help to teachers.

Suppose that a father has been drilling Junior arithmetic lessons night after night. In a friendly talk between the teacher and the father, the teacher can help the parent to make Junior interested in it. He might be persuaded to let Junior join in discussing the family budget, buying the food, using a ruler or measuring cup at home, setting the clock, calculating the distance of a trip and engaging in scores of other activities that have a mathematical basis.

If the father follows the advice, it is reasonable to say that he will soon realize that his son is making satisfactory progress in mathematics, and at the same time, enjoying the work.

Too often, however, teachers’ talks with parents are devoted to small accounts of children’s misdemeanors(不良行为). They talk about the laziness and poor work habits of the children.

What is needed is a more creative way in which the teacher, as an adviser, plants ideas in parents’ minds to make sure that the child spends the many hours out of the classroom learning something useful.

In this way the school and the home join forces in educating children.

向敏中,字常之,开封人。父瑀,仕汉符离令。性严毅,惟敏中一予,躬自教督,不假颜色。尝谓其母曰:“大吾门者,此儿也。”及冠,继丁内外忧,能刻厉自立,有大志,不屑贫窭。太平兴国五年进士,任右赞善大夫,后命为枢密直学士。
时通进、银台司主出纳书奏,领于枢密院,颇多壅遏,或至漏失。敏中具奏其事,恐远方有失事机,请别置局,命官专莅,校其簿籍,诏命敏中与咏领其局。太宗欲大任敏中,当途者忌之。会有言敏中在法寺时,皇甫侃监无为军榷务,以贿败,发书历诣朝贵求为末减,敏中亦受之。事下御史,按实,尝有书及门,敏中睹其名,不启封遣去。俄捕得侃私僮诘之,云其书寻纳筒中,奎临江传舍。驰驿掘得,封题如故。太宗大惊异。时西北用兵枢机之任专主谋议敏中明辨有才略,遇事敏速。
真宗即位,命敏中为鄜延路缘边安抚使,俄还京兆。是冬,真宗幸澶渊,赐敏中密诏,尽付西鄙,许便宜从事。敏中得诏藏之,视政如常日。会大傩,有告禁卒欲倚傩为乱者,敏中密使麾兵被甲伏庑下幕中。明日,尽召宾僚兵官,置酒纵阅,无一人预知者。命傩入,先驰骋于中门外,后召至阶,敏中振袂一挥,伏出,尽擒之,果各怀短刃,即席斩焉。既屏其尸,以灰沙扫庭,张乐宴饮,坐客皆股栗,边藩遂安。
天禧初,进右仆射兼门下侍郎,监修国史。是日,翰林学士李宗谔当对,帝日:“朕自即位,未尝除仆射,今命敏中,此殊命也,敏中应甚喜。”又曰:“敏中今日贺客必多,卿往观之,勿言朕
意也。”宗谔既至,敏中谢客,门阑寂然。宗谔与其亲径入,徐贺曰:“今日闻降麻,士大夫莫不欢慰相庆。”敏中但唯唯。又曰:“自上即住,未尝除端揆,非勋德隆重,眷倚殊越,何以至此。”敏中复唯唯。又历陈前世为仆射者勋德礼命之重,敏中亦唯唯,卒无一言。既退,使人问庖中,
今日有亲宾饮宴否,亦无一人。明日,具以所见对。帝日:“向敏中大耐官职。”

[注] ①榷务:宋设立的管理贸易和税收的机构。②降麻:唐宋任免将相。③端揆,指相位。
