【摘要】 我是一个职高的数学教师,近几年,由于普高的扩招,职高生源越来越差,大部分学生不参加中考而被提前招生。我们面对的是缺乏学习动机,没有学习兴趣和在学习中屡遭挫败,缺乏自信甚至放弃数学学习的学生,传统的数学教学面临巨大困难。因此,要提高职高数学教学质量,关键是转变学生的认识和培养学生学习数学的兴趣。因为兴趣是求知的先导,兴趣作为一种个性心理特征,在认知过程中,具有积极的促进作用。如果兴趣提高了,那么观察就细致了、记忆就深刻了、思维也敏捷了,成绩自然就提高了。近几年来国内外研究所证明的合作学习所取得的主要教育成果有15项,国内外数学教育改革中培养和激发学生的学习兴趣的研究大体上可以归纳为42种方法,而这些方法中大多是根据心理学的一般结论和教学经验进行定性讨论,研究多为描述性的。我的课题着重于:多媒体环境下协作式学习模式对职高学生学习兴趣的定性与定量相结合的研究。在本课题的研究过程中我主要采用了五种方法,分三个阶段进行影响。即:教育文献研究法、实验研究法、问卷调查法、观察法、个案研究法。第一阶段:采用学生小组成绩分工法(STAD)协作式学习创设和谐氛围,培养学生的学习兴趣。这个阶段又从下面几个方面论述课堂教学中如何激发学生学习兴趣的: (1) 利用计算机辅助教学讲解概念突破难点协作学习激发学生兴趣。(2) 运用计算机的动态效果提高学生学习兴趣。(3) 先播放录象观察数学实验,再让学生协作“动手操作”能激发起学生的学习兴趣和好奇心。(4) 解题训练中应用计算机开展协作学习提高学生学习兴趣。 (5) 在课堂上把握好媒体运用的契机,实现媒体优组激发学生学习兴趣。(6) 利用情感因素“以情传情”激发学生兴趣。(7) 通过游戏活动,使课堂气氛妙趣横生,激发学生对学习产生浓厚的兴趣。(8) 利用学生争强好胜的心理,引入竞赛法激发学生兴趣。第二阶段: 采用小组-游戏-竞赛法协作式学习激发外在动机,培养学习兴趣。竞赛是按照人们的自尊需要、成就需要而激发人们努力向上的一种手段。现代生理学研究认为,当前人脑的功能,只有10%左右被利用,还有90%的潜力有待挖掘。通过竞争可以引起大脑某些部位紧张,使处于“休息”状态的部位进入工作状态。学生都有争强好胜的特点,竞赛为学生积极参与竞争创造了条件。引导学生适当开展一些竞赛性活动,能促进学生用全部精力和智慧投入比赛中,唤起学生的内驱力,激发学习兴趣,调动学生学习的积极性和主动性。同时,还可培养学生果断、顽强、坚毅和合作的精神,收到教学中意想不到的效果。第三阶段:学生互评、互查、互考的协作式讨论及其教学模式(复习课)。在近一年的探索中,我感觉到科研和教研、科研和教学是能和谐地结合起来的。更感觉到,在探索之路上,我和孩子们共同成长。通过实践,多媒体环境下的协作式学习的学习方式不仅改变了职高传统单一的教学方式,活跃了课堂气氛,提高了学生学习兴趣,加强了协作意识、协作技能和协作性作业能力的培养,而且使学生真正成为了学习的主人,他们的成绩明显高于对比班,显示出强大的生命力。由于时间关系,研究还不够深入,所以我提出了一些需要进一步研讨的问题并为相关问题的进一步研究提出了建议。更多还原

【Abstract】 I am a math teacher of a vocational high school. Vocational high school students become worse and worse in recent years because more and more students’ go to ordinary high school. Most students come to vocational high school needn’t pass any examination. We have to face big problem by using traditional method, because our students lack study motivation, they have no interest in study, even hate study. So how to improve math education quilty, key point is how to make students be more interest in study. Because interest is guide to study. As a personal character interest can motivate people in study. If students be more interest in study, they will be more careful in watching, they can remember it more deeply, and think more quickly. So their study can be improved easily.Co-study has got 15 achievements in the rearch of recent years. In math teaching reform in the world, there are about 42 reseach methods. Most of these methods just use discussion method according to some psychology conclusion and teaching experience. I am studying in the research of combine how to determine the amount of the components of vocational high school students and how to determine the nature of vocational high school students under the cooperation of multi-media study method.I use five methods during the three steps in the studying of the article, such as, study education document, experiment, test paper, watch. During the first step, in order to increate students’ study interests I create a harmonious condition by using STAD. (l)Create students’ study interest by using computer assist system for some key points. (2)Use computer’s exhibition function. (3)Let is work together after watching some math experiment video to increase students study interest and anxious. (4)Use computer in students’ study cooperation training to create students’ study interest. (5)Use multi-media at the right time during the class to attract students. (6)Use emotion method. (7)Do some little game in class. In the 2nd step: I use unit-game-competition method to create students’ study motivation, train students’ study interest. Competition is a method that can satisfy the need of people’s self-respect. Modern biology reachers tell us only 10 percent of human’s brains arebeing used at a time, the others relax most of time. So we try to make these part of students’ brain work in competition, Because most of students want to be the best in it. In the 3rd step, let students judge, check, and test each other.During my further investigation and study certain special field. I feet scientific research and Teaching research, scientific research and Teaching can be combined. I’ve been impressed on growing with my students in the long period of teaching. According to my experience, Using co-study method through multi-media condition in class not only change The traditional and simple teaching method used in vocational schools, Warm up The students, improve their interests. Strengthen students’ cooperation consciousness.Cooperation skills and cooperation ability, but also make students. become the owner of learning. Their marks are much higher than other classes.Because the time is limited. I can’t make further research, so I put forward some discussing question and make suggestions for some interrelated questions to further study.更多还原
