学习、能力、任务、需求和元认知的复杂关系(头脑风暴)
2009-11-14 13:51:43
KEMIN:我们会一般人都会读报读文章,但不是每个人都能写文章,可见,会读与会写(不指被动抄写,指主动创写)不是一个能力层次;再又,会写的能力也可以根据写得如何再分能力层次。根据布卢姆的学习能力层次可得,会读属于领会能力层,会写属于运用能力层。
1# 学习结果与能力层次
布卢姆:知识(Knowlwdge)、领会 (Comprehension)、运用(Application)、分析(Analysis)、综合(synthesis)和评价 (Evaluation)。
加涅:言语信息、智慧技能、认知策略、态度和动作技能。
KEMIN:要理解学习目标,就离不开对学习的目的把握。如果学习是为了提高人的能力,那么问题转向,能力是什么?有多少种类?怎么评级能力强度?
他跳舞很棒,他唱功不错,他文笔很好,他很聪明,他很幽默,他很友好,
他是学生,他是硕士,他是博士,他是CEO,他是
2# 人的技能的表现
大脑:读、写、说、思
四肢:手、脚
3# 能力与任务
能力是一种做功机制,分先天和后天。
能力种类源于任务的种类,所以能力的分类转向任务的分类,那任务是什么?任务的其中一种分法是,分工作任务与创作任务,
由于对于大脑来说,工作是种很复杂的过程,是种很复杂的认识对象,所以必须把工作与创作分开研究,虽然在某些情境二者有联系
4# 工作任务与创作任务
工作是一种按步就班完成某种预定任务的过程,工作是为满足一定的需求(一般是静态的需求),并产生一定的效益和价值,比如维护系统良性运行;
工作过程就像一个多路分支流程,工作内容变量限定在有限的值域内。比如
START 选择输入(条件)变量 x
CASE A
工作处理A
CASE B
工作处理B
CASE C
工作处理C
CASE ELSE
忽略或转给上级处理
END
创作是一种特殊的工作,无明确的工作步骤,也无明确的预定任务目标,创作的特点是它有新东西新模式产生,新模式满足动态需求从而比一般的工作产生更大的价值,比如设计和创新;所以研究创作转为研究何为动态需求。
5# 创作任务与动态需求
动态需求是什么?
动态需求似乎是无时不有的,从我们每天在成长可以看出来,因此我们也无时不在在做自我“创作”,只是这种创作是无意识的,效率有限。
KEMIN:问题进一步转向,对创作的研究转向对自身发展需求来源的认识。
由我们一般人都是在无意识下被动地对外界进行认知可得,元认知的任务就是把这种随意的自我创作变为有意的自我创作,并强化。
6# 动态需求与机会
“流动性越强的地方机会越多,危机也越多,风险也越高”,什么叫流动性强?什么又叫机会呢?为什么机会与危机相伴相生的呢?
第一,从系统发展的角度看,流动性强意味系统与环境交换物质和能量越频繁,提高了成长的速率;
第二,机会是指系统与环境交换物质的事件的发生,并且交换的物质是假定有利系统发展的;
第三,因为无法预知交换物质的好与坏,所机会与危机相伴相生。
因此可得,如何提高学习效率,加速自我创作的速度的问题转向:
第一,如何提高系统与环境的流动性;
第二,如何清晰化系统自身性质;
第三,如何清晰化交换物质的性质,并对其有利于系统与否作出判断。
要解决这些“如何”,必须提供给具体个案的半自动策略参考
7# 元认知任务是工作任务还是创作任务?
元认知的任务是监控和调控学习过程,建立独立学习的能力。
独立学习的能力(元认知能力似乎与四肢能力和一般的思维能力不在一个层次上,元认知能力是一种特殊的思维能力?因为元认知任务的对象是学习过程)
|
唱功-阅读能力-写作能力-演说能力-思考能力
如何监控和调控学习过程?这就要看学习的过程是怎样的了。
8# 学习过程
学习必起始一种刺激,并对刺激进行分析,终于对学习对象的综合运用,包括创造或设计。学习过程中的操作和处理有,对具体事实的归纳和对归纳结果进行新情境的演绎;还有对事实材料进行[比较]和[分类]。
8#1 分析方法(种类)
定性分析与定量分析
系统分析与结构分析
8#2 综合方式
9# 学习复杂事物的策略
9#1 大脑一侧的策略
第一,情感干扰;第二,短时记忆容量小;第三,长时记忆淡忘;第三,未知结构(认知方式);第四,尚不具有操控的能力
9#2 客观事物一侧的策略
第一,空间性;第二,时间性;第三,未知结构
9#3 复杂事物经验材料的策略
