二、幼儿自然科学中的英语渗透
自然科学中的双语教学对于拓展学生的英语词汇和丰富英语的言语有着不可替代性。英语教材比较偏重于生活的词汇和语言素材,自然科学中的知识型英语学生接触很少。自然科学中的词汇,即使是科普性的词汇在教材中比例也很低,因此无法满足现实生活和正常交往中表述事情和表达思想的需要。应该充分利用自然科学开展双语教学,丰富学生科学技术词汇和提高学生科技性英语水平。
(一)幼儿园自然科学双语要求的落实
自然科学中的教学重视教学内容与生活的联系,包括生物和生命过程、材料及其属性、物理过程和天体等。因此,自然常识学科的双语教学应该针对学生已有的生活经验和知识水平组织教学。
1.自然科学内容的选择应遵循幼儿的年龄特点、现有经验水平、兴趣倾向等。自然知识应该与幼儿的生活密切相关,是直观的、简单的、实用的内容。自然既是教育的内容,也是丰富的教育资源,教育者要充分地发掘、利用各种有效资源为双语教学服务。
2.应通过直观形象的、游戏化的教学,给幼儿提供感知、内化、使用知识的机会。幼儿的思维具有直观形象的特点,而自然常识学科的英语词汇对于幼儿来说很生疏,有的比较抽象,因此在教学时必须采取生动、具体、形象的方式(图片、录像、多媒体等),帮助学生理解教学语言,增强语言输入量,并对语言信息做出反应,使学生在直接认知自然常识知识的同时获得语言信息。在感知知识的基础上,让幼儿走进真实的自然环境,让幼儿切实体验语言信息,运用已学到的自然常识学科的语言。在教学中特别要注意运用生活经验,这是最直接、最形象的,易于引发幼儿学习英语的积极性,调动幼儿用英语表达的兴趣,更容易促使学生在生活中运用英语就自己所体验的自然常识学科的问题进行交流。
3.教学过程中重视提高语言复现率。自然科学的教学内容前后必然的直接联系较弱,幼儿学到的自然学科的英语词汇复现率不高。不注意英语词汇的复现可能会导致不是双语自然常识课,而成为自然常识课。要注意选择教学内容和组织教学内容,强化英语词汇的复现率,并不断强化一些简单的科技英语句型,让幼儿能听懂和会表达。不仅注意在一节课上提高词汇和句子的复现,而且要在单元间、学期中不断复现。

1.国外教案
Objectives
Students will
●identify and describe three states of water;
●observe and predict how water will change states.
Materials
●water
●1 electric tea kettle
●crushed ice(about 1/3 liter)
●funnel
●1 plastic liter bottle
●1 small plastic baggie
●1 rubber band
●1 black permanent marker
●1 ruler
●white paper:1 sheet per student
●crayons or colored pencils
Procedures
(1)To begin the lesson,fill an electric kettle with water and plug it in.Ask students to tell you what they think will happen when the kettle heats up.Have students watch the kettle as it heats,and ask them to tell you what they observe.Explain that steam is a form of water and that they are observing evaporation,the process by which a liquid becomes a gas.Write the words“steam”and“gas”on the board.
(2)After watching the program,hold a class discussion about water.Ask students to tell you what they learned about water.Write their comments on the board for reinforcement.
(3)Tell students that water has three states:liquid,solid,and gas.Show students the plastic liter bottle and tell them they will observe water changing into different states.Ask a volunteer to help you use the funnel to fill the bottle about one-third full with crushed ice.Have another volunteer help you place the baggie over the bottle top and seal it in place with a rubber band.
(4)Have a student help you measure the level of ice in the bottle with a ruler.Move through this part quickly before the ice melts,and ask a few students to confirm the measurement.Make sure that the class agrees with the accuracy of the measurement,then ask a volunteer to help you draw a line on the bottle that indicates the level of ice.Write the words“ice”and“solid”next to this line.
(5)Place the bottle in the sun or in a warm area of the classroom where students can observe it.Have students divide a sheet of paper in half.On the upper half,they will draw pictures predicting what they think will happen to the ice in the warmth.Encourage students who are able to write words or sentences that describe their pictures.
(6)After about 30 minutes,ask students to look at the bottle and describe what they see.What has happened to the ice? What is happening in the bottle?
(7)Ask volunteers to measure the water level.When the class is satisfied with the accuracy of the measurement,ask a volunteer to help you draw a line on the bottle that indicates the new water level.Write the words“water”and“liquid”next to this line.
(8)Place the bottle in the warmth again and ask students to predict what they think will happen if the bottle stays there overnight.Have them draw pictures and,if able,write words or sentences on the lower half of the paper.
(9)The following day have students observe the changes that occurred in the bottle.What has happened to the water level? Where did the water go? Point out the droplets of water that have formed in the baggie.How did the water get into the baggie?
(10)Have students share their observations and talk about the accuracy of their predictions in a class discussion.Talk about temperature and how it helps water change states.Ask students to tell you about the different forms of water and to describe how water changes from one state to another.
