【摘要】：5E學習環(huán)(5E learning cycle)教學模式在1989年由美國教育專家貝比提出,是基于探究的一種教學策略和課程模式。包括緊密相連的五個環(huán)節(jié)構成:參與(Engage)、探究(Explore)、解釋(Explain)、精致(Extend)、評價(Evaluate)。因為每個環(huán)節(jié)英文首字母為“E”,所以稱為5E學習環(huán)教學模式。5E學習環(huán)教學模式的精髓在于探究環(huán)節(jié),在探究環(huán)節(jié)中領悟科學家研究自然界的方法,發(fā)展科學探究的能力,增進對科學探究的理解,學習基本的實驗能力。圖示教學法是在教學過程中,按照知識內在的聯(lián)系,用精煉的文字、數字和各種特定的符號貫穿連接起來,形成科學的知識體系。在化學教學中可借助微觀模型圖、思維導圖、概念圖、動態(tài)圖等開展教學,達到直觀形象、化繁為簡、化淡為奇的效果�！犊荚囌f明》中對學生的圖像信息處理能力要求如下:“能將分析解決問題的過程和成果,用正確的化學術語及文字、圖表、模型、圖形等表達,并做出解釋的能力�！毙抡n程改革對培養(yǎng)學生的圖像信息處理能力更加注重,各地的教科書圖文并茂。因圖像問題涵蓋知識面廣,而且能很好的考察學生的圖像信息處理能力,深受高考命題專家的青睞。本論文研究的問題是:如何在實踐中實施5E學習環(huán)教學模式輔之圖示法教學?5E學習環(huán)教學模式輔之圖示法對培養(yǎng)學生圖像信息處理能力有無影響? 5E學習環(huán)教學模式輔之圖示法對學生的圖像信息處理能力產生了怎樣的影響(主要是繪圖能力和析圖能力方面)?本論文在研究5E學習環(huán)教學模式、圖示法和培養(yǎng)學生圖像信息處理能力的策略理論的基礎上,將理論應用于實踐。參照蘇教版高一化學《必修2》展開,研究對象是高一年級平行班的學生,采用的教學方法是5E學習環(huán)教學模式輔之圖示法,經過探索階段和修正階段后逐步掌握適合學生的方法。本論文研究的結論是:5E學習環(huán)教學模式輔之圖示法在高中化學教學中是可行的,具體的環(huán)節(jié)包括參與→探究→解釋→精致→評價,圖示法可以根據具體內容滲透于各個環(huán)節(jié)。實踐結果表明5E學習環(huán)教學模式輔之圖示法教學能夠提高學生圖像信息處理能力,學生的繪圖和析圖能力也得到了顯著的提高。課堂教學中學生參與度提高,激發(fā)了學生的探究積極性,增強了學生將知識應用于圖像信息處理問題的能力。
[Abstract]:5e learning loop (5e learning cycle) was proposed by American education expert Bebe in 1989. It is a kind of teaching strategy and curriculum model based on inquiry. It consists of five closely connected links: participating in the (Engage), study of (Explore), interpretation of (Explain), refined (Extend), evaluation of (Evaluate). Because the first letter of each link is "E", the essence of the teaching model called "5e learning ring". The essence of the "5e learning ring teaching model" lies in the inquiry link, in which scientists understand the methods used by scientists to study nature and develop the ability of scientific inquiry. Improve understanding of scientific inquiry and learn basic experimental skills. In the process of teaching, the graphic teaching method is to form a scientific knowledge system by using the refined characters, numbers and various special symbols in accordance with the inherent connection of knowledge. In chemistry teaching, teaching can be carried out with the help of microscopic model map, thinking map, concept map, dynamic map and so on. The students' ability to process the image information in the examination instructions is as follows: "can analyze the process and result of solving the problem and express it with correct chemical terms and words, charts, models, graphics, etc.," And the ability to explain. " The new curriculum reform pays more attention to cultivating students' ability of image and information processing. Because the image problem covers a wide range of knowledge, and can well investigate the students' ability of image information processing, it is favored by the college entrance examination proposition experts. The question of this thesis is: how to carry out the 5e learning ring teaching mode in practice? 5e Learning Ring Teaching method? 5e Learning Ring Teaching method has an impact on the cultivation of students' Image Information processing ability How does the pattern-aided graphic method affect the students' ability of image information processing (mainly in the aspect of drawing ability and analyzing ability)? Based on the study of 5e learning loop teaching mode, graphic method and the strategy theory of cultivating students' ability of image information processing, this paper applies the theory to practice. Referring to the chemistry of the first grade of the Su education edition < required course 2 >, the object of the study is the students in the parallel class of the first grade of senior high school. The teaching method used is the graphic method supplemented by the 5e learning ring teaching model. After the exploration stage and the revision stage, gradually grasps the suitable student's method. The conclusion of this paper is that it is feasible to use the diagram method in senior high school chemistry teaching with the help of the teaching model of the learning ring of "5e". The specific links include participation in the exploration, explanation and delicate evaluation, and the graphic method can permeate every link according to the concrete content. The practical results show that the graphics teaching method assisted by the 5e learning loop teaching mode can improve the students' ability of image information processing, and the students' ability of drawing and analyzing pictures has also been improved significantly. The increase of students' participation in classroom teaching stimulates the students' enthusiasm of inquiry and enhances the students' ability to apply knowledge to image and information processing.
