1、Zone of Proximal Development,Les Vygotsky,杨林燕 漆雪彬 李月,Contents,Origins,The concept of the zone of proximal development (ZPD) was originally developed by Vygotsky to argue against the use of academic, knowledge-based tests as a means to gauge students intelligence. Vygotsky argued that rather than exa

2、mining what a student knows to determine intelligence, it is better to examine their ability to solve problems independently and their ability to solve problems with the assistance of an adult.,Vygotsky,Lev Vygotsky (1896-1934) was a Russian psychologist. He worked on child development, play and lan

3、guage. He also developed a holistic theory of human cultural and biosocial development. 1934, he died of TB.,Vygotsky,Vygotskys view is that language has two functions: external communication with ones fellow human beings and, equally important, the internal manipulation of ones inner thoughts.

The child guides its behavior by using a kind of self-talk or “thinking out loud.“ Initially, self-talk is very much a tool of social interaction and this tapers to negligible levels when the child is alone. Gradually, self-tal

ISBN 0-674-57629-2,Introduce the Zone of Proximal Development,Vygotsky stated that a child follows an adults example and gradually develops the ability to do certain tasks without help or a

7、ssistance. Vygotskys often-quoted definition of ZPD presents it as the distance between the actual developmental level as determined by independent problem solving and the level of potential development as determined through problem solving under adult guidance, or in collaboration with more capable

8、 peers. Vygotsky among other educational professionals believes the role of education to be to provide children with experiences which are in their ZPD, thereby encouraging and advancing their individual learning.,A six-year old boy who lost his toy and asks his father for help. father: when is the

9、last time you see the toy? boy: I dont remember. father: is it in your room? boy: no. father: is it in the yard? boy: no. father: is it in the kitchen? boy: no. father: is it in the car? boy: yes, i think so. Then the boy run to get the toy. In this dialogue, insread of find the toy for his son, the

10、 father helped the boy to remember where he left the toy.,The problem is solved under adult guidance, or, the problem solved in collaboration . and next time when the boy forget something again, he could use these strages to remember.,Scaffolding,The concept of the ZPD is widely used in world to stu

11、dy childrens mental development as it relates to education. The ZPD concept is seen as a scaffolding, a structure of “support points“ for performing an action. Scaffolding is a process through which a teacher or more competent peer helps the student in his or her ZPD as necessary, and tapers off thi

12、s aid as it becomes unnecessary, much as a scaffold is removed from a building during construction. “Scaffolding is the way the adult guides the childs learning via focused questions and positive interactions.“This concept has been further developed by Ann Brown, among others. Several instructional

13、programs were developed on this interpretation of the ZPD, including reciprocal teaching and dynamic assessment.,Facilitator,a facilitator helps other people develop their own capabilities and inner resources in order to perform tasks successfully. in this view, the teachers main concern is to facil

14、itate the learners accomplishment of the difficult job of learning a new language. the facilitator helps, but does not tell. the facilitator encourages, but does not criticize.,The ZPD of a child isnt stagnant, it continuously changes as he or she conquers increasingly difficult work over time. Focu

15、sing more on education, ZPD can be useful to educators because it should remind them how students can be expanded to reach goals with adult direction and support.,Deficiencies,The difference of personality, recognition, ways of solving problems, degree of learning lead to inaccuracy of intelligence

The measure can not cover all the directions, which could possibly lead to the consequence that ZPD could only be one of the several potentials and furthermore, other developments of the individuals capabilities could be i

There might be individual who has two or more ZPDs.,measure,Deficiencies,As the ZPD of each student is a relatively dynamic zone, so when the student reaches the anticipated degree of learning, teachers should change their teaching methods, make teaching plans again. Different student has di

18、fferent ZPD, so teachers should make different teaching plan towards each student. As the method of each teacher is different, so as their emphasis and degree of teaching, we can not tell whether the change of the direction of ZPD of each student can be influenced or not.,education,Enlightenment,We

19、could make learning plans in accordance with our own need of development. We should both know about our abilities and potentials, such as our specialities and advantages. Do not limit yourself to the contents in the teaching materials; new learning tasks should be made according to our own circumsta

20、nces.,Student,Enlightenment,In the traditional mode of education, teacher is the provider of knowledge while student is provided. Information has been transferred from teacher to student in a single way. Vygotskys ideas about ZPD not only changed teacher into facilitator who guides, encourages and helps student develop in all directions, but also changed student into active paticipator of class. Treat education as a process of communication. Scaffolding Instruction,Teacher,Thank you!,
