  • 幼兒園大班說(shuō)課稿 動(dòng)物怎樣過(guò)冬

    幼兒園大班說(shuō)課稿 動(dòng)物怎樣過(guò)冬

    根據(jù)《幼兒園教育知道綱要》要求幼兒對(duì)周?chē)挛锔信d趣,有好奇心和求知欲,所以我選擇了《動(dòng)物怎樣過(guò)冬》來(lái)進(jìn)行教學(xué),并且小動(dòng)物又是小朋友們喜愛(ài)的,愿意親近的。讓幼兒了解動(dòng)物是怎樣過(guò)冬的和他們過(guò)冬的不同方式。我準(zhǔn)備采用以操作法和電教法為主,讓幼兒自己動(dòng)手操作、觀察,激發(fā)幼兒探索動(dòng)物生活的興趣?! W(xué)前兒童科學(xué)教育活動(dòng)的目標(biāo),是學(xué)前兒童科學(xué)教育活動(dòng)的出發(fā)點(diǎn)和歸宿。以學(xué)前兒童科學(xué)教育活動(dòng)目標(biāo)為依據(jù),確使學(xué)前兒童科學(xué)教育活動(dòng)的目標(biāo)得以實(shí)現(xiàn)。根據(jù)大班幼兒的年齡特征,我分為了三大目標(biāo):  1、認(rèn)知目標(biāo):讓幼兒了解動(dòng)物過(guò)冬的不同方式,豐富幼兒的知識(shí)。引導(dǎo)幼兒探索動(dòng)物的生活方式。獲取有關(guān)的科學(xué)經(jīng)驗(yàn)?! ?、情感目標(biāo):激發(fā)和培養(yǎng)幼兒好奇、好問(wèn)、好探索的態(tài)度。讓幼兒探索動(dòng)物的生活從中感受到極大的興趣?! ?、技能目標(biāo):讓幼兒能根據(jù)動(dòng)物生活的習(xí)性,以及過(guò)動(dòng)的不同方式進(jìn)行簡(jiǎn)單的分類。通過(guò)操作和觀察,并結(jié)合自己以有的經(jīng)驗(yàn),得出結(jié)論。

  • 大班科學(xué)《物體怎樣移動(dòng)》說(shuō)課稿

    大班科學(xué)《物體怎樣移動(dòng)》說(shuō)課稿

    “物體的移動(dòng)”除了教幼兒獲取有關(guān)的物體移動(dòng)需要的具體經(jīng)驗(yàn)外,還要對(duì)幼兒進(jìn)行相關(guān)的科學(xué)知識(shí)教學(xué),并從科學(xué)探索出發(fā),生成有關(guān)技術(shù)的目標(biāo)和內(nèi)容,將幼兒的科學(xué)與技術(shù)學(xué)習(xí)有機(jī)地、自然地結(jié)合起來(lái)。在教幼兒“物體怎樣移動(dòng)”的之前,我預(yù)設(shè)了一下“物體怎樣移動(dòng)”的學(xué)前目標(biāo):首先,引導(dǎo)幼兒在玩的過(guò)程中,自己嘗試讓物體動(dòng)起來(lái),使幼兒感受物體運(yùn)動(dòng)和力的關(guān)系,獲取有關(guān)物體移動(dòng)需要力的具體經(jīng)驗(yàn)。其次,讓幼兒嘗試用力大和用力小的時(shí)候,物體移動(dòng)的一樣嗎?再次,讓幼兒想辦法在不用身體碰物體的情況下,還有什么辦法讓物體動(dòng)起來(lái)?最后,要培養(yǎng)幼兒的觀察力,并激發(fā)幼兒探索自然現(xiàn)象的興趣。在學(xué)習(xí) “物體怎樣移動(dòng)”的時(shí)候,教師為幼兒共同準(zhǔn)備了各種物體。如:積木、汽車(chē)、紙、圓珠筆、各類玩具以及繩子、輪子、木板等等。為了讓幼兒更好的投入到活動(dòng)中去,在進(jìn)入教室之前,我領(lǐng)著幼兒在室外活動(dòng)了一下。隨后我放開(kāi)音樂(lè),幼兒聽(tīng)著音樂(lè)《碰碰車(chē)》來(lái)到了教室,看到地上放著各類玩具,頓時(shí)來(lái)了興趣。我趁機(jī)說(shuō):“小朋友們,地上放了這么多的玩具,我好想玩一玩,你們想玩嗎?”說(shuō)完,我就獨(dú)自拿著玩具玩起來(lái),小朋友也跟著玩起來(lái)。在我的啟發(fā)和引導(dǎo)下,孩子們開(kāi)始了活動(dòng)中的第一次嘗試,在這一環(huán)節(jié)中,教師給了幼兒自由探索的空間和材料,讓幼兒通過(guò)嘗試,發(fā)現(xiàn)物體自己是不動(dòng)的,只有去推它碰它物體才會(huì)移動(dòng)。

    The theme of this section is to express people's views on studying abroad. With the continuous development of Chinese economic construction, especially the general improvement of people's living standards, the number of Chinese students studying abroad at their own expense is on the rise. Many students and parents turn their attention to the world and regard studying abroad as an effective way to improve their quality, broaden their horizons and master the world's advanced scientific knowledge, which is very important for the fever of going abroad. Studying abroad is also an important decision made by a family for their children. Therefore, it is of great social significance to discuss this issue. The theme of this section is the column discussion in the newspaper: the advantages and disadvantages of studying abroad. The discourse is about two parents' contribution letters on this issue. They respectively express their own positions. One thinks that the disadvantages outweigh the advantages, and the other thinks that the advantages outweigh the disadvantages. The two parents' arguments are well founded and logical. It is worth noting that the two authors do not express their views on studying abroad from an individual point of view, but from a national or even global point of view. These two articles have the characteristics of both letters and argumentative essays1.Guide the students to read these two articles, and understand the author's point of view and argument ideas2.Help the students to summarize the structure and writing methods of argumentative writing, and guides students to correctly understand the advantages and disadvantages of studying abroad3.Cultivate students' ability to analyze problems objectively, comprehensively and deeply
