或者把 “直接记忆九九乘法表” vs “多做一位数乘法题” 相比,前者属于
repetition priming,后者属于 conceptual=> perceptual priming。
这样对于普通娃,乘法计算力是作为好比大众体锻达标要求(会考要求),而不是计算
竞技要求(高考要求),那样先上 conceptual=> perceptual priming,到收尾时
如果还有距离,那再用 repetition priming 强化一下达标,我觉得看起来更合理。

对美帝这边六岁普通娃(小学一年级)而言,因为没有练熟 place value,多个数字加
法仅用蛮力心算(不用 skip 5 counting 或者 skip 10 counting 的话)的话,一般
超不过 40 或 50。
所以小学一年级的数字普通娃,确实不会心算结果超过 40 或者 50 的一位数乘法。
这可能是父母热衷背诵九九乘法表的原因。但老实说看具体娃,如果不是对数字非常感
兴趣的话,又是数学普通娃,小学一年级背诵九九乘法表,娃多半还是觉得挺苦鼻的。
当然我更大的 concern 是,还是有后发型孤独症的。虽然心理学说,这些跟是不是
repetition (direct) priming implicit memory 太狠没有直接关系,但我觉得人之常
情也我不敢 “伸出一脚踹飞上帝”。
所以我很少敢推 repetition priming 的,我觉得推 “乱中取胜” conceptual-
perceptual priming,保证娃不抗拒。那最坏情况就当我白费劲就是了,风险还是小,
反正我的时间对娃娃而言不值钱就是了。

:这个,还会有人学不会一位数和一位数的乘法吗

我在考虑是否内容需要调整, 请大家给点意见. 譬如是否过多的术语,是否需要给案例,
以加深理解. 如果有同学提供他,她, 它的数据,可以作为样本来设计锻炼.
上堂课讲了aerobic intensity的测算, 因为aerobic 本身就是非常大的题目, 所以很
多东西仅仅是浅尝辄止.入果有同学感兴趣, 可以在以后的课程中加深.
anaerobic: 就是对家看到肌肉男,(可以去做苦力).
通常有两类测试方法, RM 和 功能测试.
RM (repetition maximal ) 指最大的肌肉力量. 1RM 就是一次能举的最大量(举不动第
二下), 2RM 举两次, 以次类推.所以16RM 要远小余1RM.
这个概念使用于所有骨骼肌肉.
1RM特点, 精确, 缺点, 危险, 难于控制.
临床多用predictive RM. 就是测试10-16 RM , 然后换算成1RM, 见下表.

说实话,自我感觉这一章写得不好,因为这一章完全没有表达出我心里的意思。我想强调ritual and repetition 是平淡而非常强悍的。
Things that we repeat daily like brushing our teeth before breakfast or shower at certain time of the day become our rituals. These rituals might not be scientific or optimal, but emotional attachments are built on such rituals. Over time, these rituals emerge into our personalities, and these banal and repetitive things can help us overcome grandiose hurtles in life.

The repetitive training of a certain neuronal pathway will strengthen it and
induce some changes on protein level. However this should be different
with the changes of muscles induced by fitness practicing.
Only through non-repetitive 禅修, the detectable changes on protein level
can not happen. I think the structual changes in central/peripheral neural
system mostly happen in the synapses.
Even the structural change is induced by 禅修, the utilization of it still
needs some stimuli (under certain ... 阅读全帖

行禅在念住修行中有很重要的地位。跟大多数这儿的同学们一样,我没有福气有专门时

我曾经试着给每一步脚掌的移动分解标识“按,移,推,提”。开始感觉效果不错
,但缺点是标识经常跟不上所缘变化,导致标识变成了念口诀。后来请教卡玛兰蒂禅师

易走神被杂念打乱。到最后,我想了一个办法。这个办法跟我练习安般息念的经验有关

他没有详细解释。只是说是自己深广研究大面积材料的得到的结论。不是一句话能讲清

通过谈话和看病人画的图,他有时候能看出来病人的器官病变。并且分析了一些例子。

我好奇的去查了一下:
People with Asperger syndrome often display behavior, interests, and
activities that are restricted and repetitive and are sometimes abnormally
intense or focused. They may stick to inflexible routines, move in
stereotyped and repetitive ways, or preoccupy themselves with parts of
objects.

My points:
If the authors are not native speakers, be a bit permissive on the language
unless it is horribly written.
For grammatical errors, just point out that there are a few grammatical
errors that should be addressed during proofreading.
For your case,
Some part of the manuscript was written in an obscure way that made it hard
to understand.
There are repetitive verbiages that the authors should consider trimming or
avoiding direct repetition.
