【摘要】：今天是信息技术高速发展的时代,教育也紧跟时代前进的步伐,充分利用现有的信息化教学辅助媒体,让课堂活跃起来,这样既可以改善教学效果,也减轻了教师的负担。课堂教学是目前教学的主要形式,实践表明,良好的课堂氛围能够提升教学效果,增强课堂中教师与学生的互动、学生与学生的互动则是营造良好课堂氛围的关键。交互式电子白板作为一个集多媒体计算机、投影和黑板功能于一身的现代教学辅助媒体,其本身具有强大的交互功能,有效的交互策略能够活跃课堂气氛,同时也能提升教学效果。研究通过大量文献分析,对目前互动教学策略的应用研究进展情况有了一定的了解。文献多次指出,教师应在课堂中与学生进行更多的对话和交流,或者设计更多的课堂提问环节;互动教学策略的实施基本围绕师生的互动意识、教学条件和教师的引导来进行。该研究对初中函数的研究情况也做了深入了解。从中可以看出,现阶段初中函数教学中存在一些突出的问题,例如:学生不能灵活运用数形结合的思想解决问题等。很多学者也在不断探索解决这些问题的方法。该研究紧紧围绕三个要点来进行互动教学策略的实施:(1)增强师生课堂互动意识;(2)创设课堂互动条件;(3)鼓励学生“敢想”、“敢说”、“敢做”。针对目标学校的现状,数学课实行“分层走班制”教学,分为A班、B班、C1班和C2班。A班成绩较高,C班成绩较差,选择A班和C1班来进行为期一个学期的实验。该研究在信息技术环境下,以初中二次函数单元为例,将互动教学策略依托交互式电子白板上展示出来。通过交互策略的设计与尝试,观察课堂,追踪学生的测验成绩,以此来证明在交互式电子白板的支持下,互动教学策略的优势所在。研究表明,在交互式电子白板的支持下,在函数教学中使用互动教学策略对学生的课堂表现有很大的触动,改善了C1班的课堂氛围,也提高了A班学生的考试成绩,有助于学生应用函数知识解决实际问题,有助于学生数形结合思想的进一步发展,对学生函数知识的掌握具有促进作用。尤其是对A班粘液质的学生产生了积极的影响,从而证明互动教学策略在基础较好的粘液质类型的学生身上有明显的优势。
[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.
