3. Relations between learning & memory • Memory: One important aspect of learning which deals with learning information, i.e. attending, pre-coding, selecting, coding and recoding, storing, outputting, etc.. 记忆：学习中涉及信息处理的一个重要方面，包括注意、预编码、选择、编码和再编码、储存、输出，等等。 • Learning is not only a process to deal with information, but also a process of change of the learner in thinking logic and behaviour. 学习不仅仅是一个信息处理的过程，还包括了学习者思维逻辑和行为变化等等。

4. Three stages of information process in learning学习过程中信息处理的三个阶段 • The sensory register (function: selective attention) 感觉登记（感觉记忆）（作用：注意选择） • Working memory (function: thinking) 工作记忆（作用：思考） • Long-term memory(function:storage and recall) 长时记忆（作用：储存和回想）

5. Three memory systems in processing input Plan Input from environment Selected input Processed input Precoding Consciousness Sensory register Working memory Long term memory Processing a more elaborate handling of material to ensure long term retention ( up to one minute) Attending very quick scanning of input for importance (up to one second) Storing input now Processed and Available for recall (up to a lifetime)

6. 1. The Sensory Register感觉记录 • The first stage in information processing; a brief (about1/4 to 1 second) period during which information is held and scanned. 是感觉刺激停止之后所保持的瞬间映像，它是信息处理的第一个阶段，大约有1/4秒到1秒，在这期进行信息扫描。

7. Sensory register depends on several factors such as the strength of the stimulus. 感觉记录取决于一些因素，诸如刺激的强度。 • The function of sensory register is to sort input information into ‘important’/’reject’ categories. 感觉记录的作用是把输入的信息分为‘重要的’/‘可舍弃的’两类。

8. Important concepts related to sensory register • Attending 注意 • Value 价值 • Mental set心向 • The physical properties of stimulus 刺激物的物理特征 • Physiological or internal states 生理或内在状态 • Precoding预编码 • presetting 预设

9. Arousal:激发 The system acts as the source of the energy that drives the process. 推动记忆运作的动力系统 Plan Input from environment Selected input Processed input Precoding Consciousness Working memory Long term memory Sensory register Variation Prevailing set Arousal system

10. The general relation between arousal and quality of mental performance could be showed as an inverted U curve可以用一条倒U曲线来描述“激发”与思维表现质量之间的一般关系

11. Wired up the arousal system引起激发的方式 • Variation 变化 • Stimuli that are relevant to a prevailing physiological or psychological set 与带倾向性的物理或心理定势相关 • Anxiety 好奇 • Physical exertion 身体兴奋

12. Enlightens to teaching • Variability in style of teaching 教学形式多样化 • Variability in media and materials of instruction 媒体与教学资源多样化 • Keep anxiety 保持好奇心 • Physical excitement and freshmen 保持身体兴奋和清醒

13. 2、Working Memory工作记忆 • Working memoryrelates to where we are conscious of what we are thinking about. It is of limited capacity, so information needs to be chunked, either: 工作记忆是指个人当时注意着的信息，是唯一对信息进行有意识加工的记忆阶段，它的容量有限, 所以信息需要编成组件（信息的一种意义单位），组件的方式有： • By rehearsal, which leads to rote learning; 复述（它导致机械学习） • By coding, which leads to meaningful learning 编码（它导致意义学习）

14. Needed for all cognitive activities 所有认知过程都有赖于工作记忆 Limited in capacity 容量有限 Based on one’s psychological quality 基于人的心理素质 Optimising the use of working memory 最大限度地发挥工作记忆的作用 Organization of chunk 构建思维组件 Psychological states 心理状态 Working Memory

15. Use imagery 利用表象 Recycle 重复 Rehearse 背记 Coding & Recoding 编码与重编码 Ways of processing in working memory

16. Three important concepts • Precoding预编码 • The process, which takes place in the sensory register, of selecting a particular train of information for conscious attention on the basis of its current importance. 在感觉记录中进行的过程，依据这些信息在当前的重要性筛选出一组特定的信息予以有意识的注意。

17. Coding Reading in, interpreting and understanding input in terms of existing coded knowledge. 用已编码的知识对新输入的信息进行读入、解释和理解的过程。 • Recoding Change in codes or cognitive structure brought about as a result of mismatch (see also match). With the optimal degree of mismatch, cognitive structures grow more complex and intrinsic motivation is experienced. 由于错开而引起认知结构或编码的改变(在偶合时也可见)。当错开的程度最为恰当时，认知结构进一步复杂化，内发的动机发生作用。

18. Two important factors that affect coding: 影响编码的两个重要因素 • Pre-knowledge 原有知识 • Method of coding编码的方法

19. Dimensions of coding编码的类型 • Enactive – motor skills 动作－运动技能 • Sensory – raw experience 感觉－自然经验 • Affective – feelings and emotions 情意－感知与感情 • Temporal – time flows 时间－时间感 • Spatial – space and position 空间－空间与位置 • Semantic – word meaning 语义－词语意义 • Logic – logical structure逻辑－逻辑结构

20. 3、Long-term Memory长时记忆 • Long-term memory: Storage of previous learning to be reconstructed when appropriate in working memory. 长时记忆是指原来习得的知识储存，在恰当的时候可在工作记忆中重新进行建构。

21. Three theories on long-term memory • Trace Decay痕迹衰退 Memory traces ‘decay’ over time 记忆痕迹随着时间的推移而逐渐消退 • Associative Interference关联干扰 Memories of similar events interfere with each other 相似事件之间的记忆的互相干扰 • Coding Within a Structure结构内编码 Relate learning with pre-knowledge and building a framework 在原有知识基础上进行学习并建立一个框架

23. What can we learn? • It is important to arouse students’ attention. 唤起学生的注意非常重要 • Good learning involves: 高水平的学习应包括： • A variety of dimensions being used for coding. 从多个方面进行编码 • The highest levels of abstraction that the learner can handle. 学习者能够把握最高的抽象水平 • Try to teach in terms of meaningful learning. 根据有意义学习的要求进行教学

24. In Teaching, we focus on encouraging students to consciously desire to attend, and by using variability: in teaching mode; in content; in media; and in student-teacher interaction. 在教学中通过多样化的教学方式，教学内容，教学媒体，师生互动，来激励学生有意识的注意。

25. How to teach meaningfully怎样进行有意义的教学 • See that the task is properly structured and is understandable。 确保任务的结构合理并且是可理解的。 • See that the task is at the right level of difficulty. 确保任务的难度适当。

26. See that the task is codeable in multiple ways. 确保任务可以通过多种方法编码。 • See that the learner is active when coding the task. 确保学习者主动地对任务编码。

27. Discussion • Discuss the relation between memorising and learning. • Give examples to explain processing in the three stages of memory. • How many ways of processing do you know in working memory. Discuss the role of repetition in memorizing and in understanding. • Compare the three concepts: precoding, coding and recoding. Explain your understanding with two examples for each concept. • Why meaningful learning is important? Give examples to explain how students’ pre-knowledge works in learning.

28. 讨 论 • 讨论记忆和学习的关系。 • 用实际例子说明记忆过程的三个阶段是如何进行的。 • 工作记忆中有多少种处理信息的方式？讨论重复对记忆和理解的作用。 • 比较预编码、编码和重新编码（再编码）三个概念。每个概念举两个例子进行说明。 • 为什么说有意义学习是很重要的？用实际例子说明学生原有知识在学习中如何起作用。
