家庭中实施幼儿社会教育有其独特的优势。家长和孩子有血缘关系、亲子感情融洽。教育对象单一,便于有针对性地个别施教。家长和孩子生活在一起,随时发现问题随时施教,不受其他因素的限制。施教者固定,有利于教育的一贯性。但是,家庭中实施社会教育也容易犯过于感情用事的毛病。

    Recently. a survey was done among 288,000 students. which shows that today's traditionalage college

freshmen are "more materialistic and less altruistic (利他主义的)" than at any time in the 19 years of the

poll(民意调查).

      Not surprisingly. in these hard times. the students' major purpose "is to be financially well off."

Developing a meaningful philosophy of life is less important than ever. It follows then that today the most

popular course is not literature or history but accounting.

     Interest in teaching. social service and the "altruistic" fields is at a low. On the other hand. enrollment

in business programs. engineering and computer science is way up.

      That's no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors in her first year on the job-even before she completed her

twoyear associate degree.

     Though it's true that we all need a career. it is equally true that our civilization has accumulated an

incredible amount of knowledge in fields far beyond our own and that it will be better for our

understanding of these other contributions-either scientific or artistic.

     Similarly. it is true that. in studying the diverse wisdom of others. we learn how to think. More

importantly. perhaps. education teaches us to see the connections between things. as well as to see

beyond our immediate needs.

     Weekly we read of unions who went on strike for higher wages. only to drive their employer out of

business. No company. no job. How shortsighted in the long run!

But the most important argument for a broad education is that in studying the accumulated wisdom of the

ages. we improve our moral sense. I saw a cartoon recently which shows a group of businessmen looking puzzled as they sit around a conference table;one of them is talking on the intercom (对讲机) : "Miss

Baxter. " he says. "could you please send in someone who can distinguish right from wrong?"

     From the longterm point of view. that's what education really ought to be about.
