U-shapedDevelopment课件

DefinitionU-shaped Development is(Also known as“U shaped Learning”)is the typical pattern by which select physical,artistic,and cognitive skills are developed It is called“U”shape development because of the shape of the letter U in correlation to a graph,skills developed in the“U shaped”fashion begin on a high position on a graphs Y-axis(Y 轴轴）.The skills start out at a high performance level and over time the skills descend to a lower position on the Y-axis.After another period of time the skill once again ascends to a higher position on the y-axis.U-shaped development can be seen in cognitive skills such as learning new words,or doing high level algorithms（运算法则）in mathematics the skill can also be artistic such as painting or playing a musical instrument,and physical skills such a walking and weight lifting.“U-shaped development”refers to the peculiar phenomenon in which learners can appear to forget,temporarily,what they have already learned.This goes contrary to the conventional wisdom that conceptual understanding and performance ability are tightly coupled and increase together.U-SHAPED DEVELOPMENT OF NEWTONIAN CONCEPTS FromExamplesSheep sheepssheepTaketakedtookHow are you?Fine thank you!How is everything going?P=F/SF=PS陈姿谕陈姿谕 陈秀丹陈秀丹
