【摘要】：今天是信息技術(shù)高速發(fā)展的時(shí)代,教育也緊跟時(shí)代前進(jìn)的步伐,充分利用現(xiàn)有的信息化教學(xué)輔助媒體,讓課堂活躍起來(lái),這樣既可以改善教學(xué)效果,也減輕了教師的負(fù)擔(dān)。課堂教學(xué)是目前教學(xué)的主要形式,實(shí)踐表明,良好的課堂氛圍能夠提升教學(xué)效果,增強(qiáng)課堂中教師與學(xué)生的互動(dòng)、學(xué)生與學(xué)生的互動(dòng)則是營(yíng)造良好課堂氛圍的關(guān)鍵。交互式電子白板作為一個(gè)集多媒體計(jì)算機(jī)、投影和黑板功能于一身的現(xiàn)代教學(xué)輔助媒體,其本身具有強(qiáng)大的交互功能,有效的交互策略能夠活躍課堂氣氛,同時(shí)也能提升教學(xué)效果。研究通過(guò)大量文獻(xiàn)分析,對(duì)目前互動(dòng)教學(xué)策略的應(yīng)用研究進(jìn)展情況有了一定的了解。文獻(xiàn)多次指出,教師應(yīng)在課堂中與學(xué)生進(jìn)行更多的對(duì)話和交流,或者設(shè)計(jì)更多的課堂提問(wèn)環(huán)節(jié);互動(dòng)教學(xué)策略的實(shí)施基本圍繞師生的互動(dòng)意識(shí)、教學(xué)條件和教師的引導(dǎo)來(lái)進(jìn)行。該研究對(duì)初中函數(shù)的研究情況也做了深入了解。從中可以看出,現(xiàn)階段初中函數(shù)教學(xué)中存在一些突出的問(wèn)題,例如:學(xué)生不能靈活運(yùn)用數(shù)形結(jié)合的思想解決問(wèn)題等。很多學(xué)者也在不斷探索解決這些問(wèn)題的方法。該研究緊緊圍繞三個(gè)要點(diǎn)來(lái)進(jìn)行互動(dòng)教學(xué)策略的實(shí)施:(1)增強(qiáng)師生課堂互動(dòng)意識(shí);(2)創(chuàng)設(shè)課堂互動(dòng)條件;(3)鼓勵(lì)學(xué)生“敢想”、“敢說(shuō)”、“敢做”。針對(duì)目標(biāo)學(xué)校的現(xiàn)狀,數(shù)學(xué)課實(shí)行“分層走班制”教學(xué),分為A班、B班、C1班和C2班。A班成績(jī)較高,C班成績(jī)較差,選擇A班和C1班來(lái)進(jìn)行為期一個(gè)學(xué)期的實(shí)驗(yàn)。該研究在信息技術(shù)環(huán)境下,以初中二次函數(shù)單元為例,將互動(dòng)教學(xué)策略依托交互式電子白板上展示出來(lái)。通過(guò)交互策略的設(shè)計(jì)與嘗試,觀察課堂,追蹤學(xué)生的測(cè)驗(yàn)成績(jī),以此來(lái)證明在交互式電子白板的支持下,互動(dòng)教學(xué)策略的優(yōu)勢(shì)所在。研究表明,在交互式電子白板的支持下,在函數(shù)教學(xué)中使用互動(dòng)教學(xué)策略對(duì)學(xué)生的課堂表現(xiàn)有很大的觸動(dòng),改善了C1班的課堂氛圍,也提高了A班學(xué)生的考試成績(jī),有助于學(xué)生應(yīng)用函數(shù)知識(shí)解決實(shí)際問(wèn)題,有助于學(xué)生數(shù)形結(jié)合思想的進(jìn)一步發(fā)展,對(duì)學(xué)生函數(shù)知識(shí)的掌握具有促進(jìn)作用。尤其是對(duì)A班粘液質(zhì)的學(xué)生產(chǎn)生了積極的影響,從而證明互動(dòng)教學(xué)策略在基礎(chǔ)較好的粘液質(zhì)類(lèi)型的學(xué)生身上有明顯的優(yōu)勢(shì)。
[Abstract]:Today is the era of the rapid development of information technology, education also closely follow the pace of the times, make full use of the existing information teaching auxiliary media, so that the classroom is active, this can not only improve the teaching effect, but also reduce the burden on teachers. Classroom teaching is the main form of teaching at present. Practice shows that a good classroom atmosphere can improve the teaching effect, enhance the interaction between teachers and students in the classroom, and the interaction between students and students is the key to create a good classroom atmosphere. Interactive electronic whiteboard as a multimedia computer, projection and blackboard functions in one of the modern teaching aids, its own powerful interactive function, effective interaction strategies can be active classroom atmosphere, At the same time, it can also improve the teaching effect. Through a lot of literature analysis, the research has a certain understanding of the current research progress in the application of interactive teaching strategies. The literature has pointed out many times that teachers should have more dialogue and communication with students in class, or design more classroom questioning links, and the implementation of interactive teaching strategies basically revolves around the interactive consciousness of teachers and students, the teaching conditions and the guidance of teachers. This study also makes a deep understanding of the study of junior high school functions. It can be seen that there are some outstanding problems in function teaching in junior high school at present, for example, students can not solve problems by using the thought of combining numbers and shapes flexibly. Many scholars are also constantly exploring solutions to these problems. This study focuses on three key points to implement interactive teaching strategies: 1) to enhance teachers and students' awareness of classroom interaction; 2) to create classroom interaction conditions; 3) to encourage students to "dare to think", "dare to say", "dare to do". In view of the present situation of the target school, the mathematics class is taught by "stratified walking class system", which is divided into class A, class B, class C _ 1, and class C _ 2, the results of which are lower. Class A and class C are chosen to carry out the experiment for one semester. In the environment of information technology, taking quadratic function unit of junior high school as an example, the interactive teaching strategy is displayed on the interactive electronic whiteboard. In order to prove the advantage of interactive teaching strategy with the support of interactive whiteboard, we can observe the classroom and track the students' test results through the design and attempt of interactive strategy. The research shows that, with the support of interactive electronic whiteboard, the use of interactive teaching strategies in function teaching has a great impact on students' classroom performance, improves the classroom atmosphere of Class C1, and also improves the test scores of Class A students. It is helpful for students to use functional knowledge to solve practical problems, to further develop students' idea of combination of numbers and shapes, and to promote students' mastery of functional knowledge. In particular, it has a positive effect on the students of Class A, which proves that the interactive teaching strategy has obvious advantages in the students with better basic mucus type.
