70/20/10 Model

Posted on by

The 70/20/10 Model is also used as a Learning and Development model, according to the Princeton University Learning Process.

    * 70% of learning & development takes place from real-life and on-the-job experiences, tasks, and problem solving.

This is the most important aspect of any learning and development plan. For example, the real learning from a skill acquired in a training program, or from feedback, takes place back on the job when the skill or feedback is applied to a real situation.

    * 20% comes from feedback and from observing and working with role models.

    * 10% of learning and development comes from formal training.

ANSI Common LISP

Posted on by

.

ANSI Common LISP (by Paul Graham) was the book I borrowed for a Machine Intelligence course project in 2000. My memory was that the author was called “Paul something”. I thought that Paul was the one who had invented LISP.

No. It should be John McCarthy.

Later on, during my teaching-in-high-school period, by a Wikipedia biography, I realized that that Paul was not as great as I thought, because he was not the one who had invented LISP.

However, now, I regard him as one of my five most important teachers.

反拋

Posted on by

這段改篇自 2010 年 4 月 30 日的對話。

（CSK：其實 A.Maths（附加數學）是否時常用複雜的術語，去描述一些本來很簡單的事物？）

不只 A.Maths，其他科目也是這樣。明明是淺白的東西，用了一個新的詞彙，就會好像高級一點。代價是令到初學者不知所云，浪費大量時間。

例如 ，如果我說：「f(x) 是一條有 x 的公式。 f(x) is a formula of x.」大部人也會立刻明白，而覺得很無聊。但是，數學科卻說：「f(x) 是一個『函數』。 f(x) is a function of x.」大家就好像應該肅然起敬。

（CKY：用來「拋」（嚇）人。）

無錯。所以，我們千萬不要給其他人拋到。別人拋我們時，我們要反拋他。別人用深的術語嚇我們時，我們要用（貌似）更深的術語去反嚇他。
