不属于现代信息技术优势的是(运用信息技术优势,构建高效数学课堂)
Mathematics is an abstract and logical subject. Primary school students' thinking is in the transitional stage from concrete thinking in images to abstract thinking in logic. Primary school mathematics must build a bridge
First, build a vivid situation. Arouse a strong interest in learning Psychologists say: "Students' active learning process. It is based on a strong interest. " Interest is an intrinsic motivation to promote students' learning, which can stimulate students' strong thirst for knowledge. However, primary school students are young, with short attention span and poor persistence. In addition, the classroom thinking activities are relatively tense, and students are prone to fatigue, inattention and decline in learning efficiency. At this time, teachers can make proper use of information technology, create a vivid situation, attract students' attention, ignite students' curiosity and arouse students' interest in learning through colorful images, vivid animations and realistic sound effects. In the situation carefully constructed by teachers, students will naturally have their own psychological needs to learn from the bottom of their hearts, and actively participate in learning under the control of such psychological needs. Teachers also get twice the result with half the effort in teaching, and the teaching effect is good. For example, when teaching "the understanding of the renminbi", using multimedia to show the cartoon image of "小精灵" that children like brings a nursery rhyme to everyone: "The tricycle runs fast, and there is an old woman sitting on it, asking 五毛for a piece. Is it strange?" With elegant music, even the students who don't like math class at ordinary times are full of interest. Then they ask the question: What does "五毛" and "a piece" mean in nursery rhymes? In the familiar and friendly learning situation of students, through the对dialect of teachers and students, it is logical to lead to the understanding of the subject of RMB 33,354. Students' enthusiasm was aroused and their interest in learning sprouted.
Second, the use of information technology, change static into action, change abstract into concrete, break through the teaching difficulties. The advantage of multimedia is that it can provide a large number of intuitive moving images to induce students to think independently and profoundly. For example, in the teaching of understanding rectangle and square, students should first master the characteristics of rectangle, and use the flashing function of computer to highlight that rectangle has four sides, the对sides are equal, and all four corners are right angles. Then, by using animation demonstration, when the length of the rectangle is gradually shortened to be equal to the width, the rectangle becomes a square, thus deducing the characteristics of the square. After further observation, we draw the conclusion that square is a special rectangle, and further guide students to understand that we can say that a rectangle is a square, but we cannot say that a square is a rectangle.
第三,信息技术与教学方法的整合。提高教学效率在传统的小学数学教学过程中,一切都由教师决定。教学内容、教学策略、教学方法、教学步骤,甚至学生做的练习都是由老师预先安排的,学生只能被动地参与这个过程,即处于被灌输的状态。人机交互是计算机的一个显著特征,这在任何其他媒体中都是不存在的。信息技术的应用可以改变传统的教学方法,创造一个有利于教师、学生和教学媒体双向互动的环境。例如,在《旅游数学》的教学中,教师在课前根据教学目标对对的教材进行分析、加工和补充,并以课件的形式呈现给学生。在课堂上,学生接受学习任务后,在老师的指导下选择不同的旅行路线,发现不同的数学问题并独立解决。然后,选择相同路线的学生可以通过网络进行交流和讨论,并将结果提交给机让老师进行评估。最后,老师们通过网络在大屏幕上公布每个小组讨论的结果,并在全班进行交流。利用网络环境在整个课堂上的互动,学生、教师和学生之间有良好的双向互动。同时,它也充分调动了学生认知和实践的主观能动性,以及自主学习和合作学习的能力,使学生真正成为数学学习的主人。
4.利用信息技术,拓展时间和空间,开发能力信息技术网络资源是课堂教学的延伸。无论在时间上还是空间上,它都给我们留下了广阔的发展空间。利用好它,必将使传统课堂教学发生质的飞跃。例如,在研究了角度的类型后,一些学生问,什么角度大于90度但小于180度?学生们不仅知道这个角落的名字,还可以通过在网上搜索了解更多。例如,在学了圆周率之后,在网上搜索祖冲之和圆周率的知识,学生们充满了兴趣,却知道世界是如此的大而多彩,他们被美丽所影响,这进一步激发了他们努力学习和成为天才的信心和决心!
信息技术与小学数学课程的整合无疑给传统数学教学注入了新的活力。如何充分理解信息技术,如何将信息技术与传统教学方法有机结合,优化课堂结构和教学方法,提高学生主动学习的兴趣,使学生在轻松愉快的环境中学习知识,达到提高教学效率和教学质量的目的,是教育工作者努力的方向。
