【摘要】：化学作为自然学科之一,与我们的工业生产、日常生活息息相关。高中化学作为高校选拔人才的基础性学科之一,存在知识点多、散、杂,难记、易忘的特点。特别是对于面临着高考压力的高三的学生而言,如何让杂、散、多的知识点系统化、条理化,让高三化学复习在有限时间内既全面又有实效?如何能够让高三学生真正的“动”起来积极主动参与复习,让高三化学复习的课堂彻底“活”起来呢?经过长期一线高中化学教学的实践,笔者发现“三疑三探”的教学方法给高三化学复习提供了一条有效的途径。它能促进学生更加主动地学,使教师的“教”更富有活力,同时还能锻炼学生的协作能力、培养学生敢于质疑、善于表达的能力,并从中体会到与人分享的快乐、收获成就感。这与高中化学教学以培养探究自然的化学思维方式的目标是完全一致的,这也是《课程标准》的具体体现:“教师要激励学生合作与自主探究相结合的学习方式,这样能使学生在感兴趣的自主活动中主动探究、团结合作、勇于创新、全面提高素质”。本论文以高三化学的复习中习题讲评课为主要研究对象。研究的主要内容是“三疑三探”这种教学方法在温江中学高三化学复习中习题讲评课的应用,并在此基础上总结出一套适合于温江中学的富有理论基础和实战操作的“三疑三探”之路,最后以温江中学高2013级4、5班的学生作为实验对象进行本课题的教学实践,以“三疑三探”在高三化学复习中习题讲评课的合理应用作为核心内容,并取得了令人满意的结果。本论文分为五部分:1、通过文献研究对“三疑三探”的教学方法在高三化学复习中的意义和重要性进行了说明,并在此基础上初步拟定了“三疑三探”在四川省温江中学高三化学复习课习题讲评课合理应用的措施和方法。2、对温江中学高2013级化学复习课堂的现状以及现任高三化学教学的教师进行调查。调查采用问卷调查和专家访谈的方式,以自制的问卷为测量工具,共发放问卷265份,收回265份。问卷结果显示:(1)学生普遍反应现有的高三化学复习老师讲得太多。(2)学生很欢迎“三疑三探”教学方法进入高三化学复习课堂。(3)“三疑三探”教学所用的激励机制对学生的激励作用很大。(4)将“三疑三探”应用于高三化学习题讲评课之中受到了高三化学教师的普遍认可。3、将研究总结的教学策略实践应用于温江中学高2013级4班学生,并结合案例给出实际操作流程,并得出结论:将“三疑三探”这种教学方法应用于四川省温江中学高三化学习题讲评课强烈地激发了学生的学习热情,让学生在轻松、积极的课堂氛围中养成了认真倾听、积极思考的听课习惯,提升了学生勇于表达的能力,激发了学生敢于向权威质疑的创新能力。可见,本文提出的将“三疑三探”合理应用于高三化学复习的实践改革是科学的、成功的,是有实践意义的,得到师生的普遍认同,值得推广。4、通过本课题的研究初步形成了“三疑三探”在高三化学复习习题讲评之中试卷讲评课的实践操作流程,积累了较为丰富的高三化学复习的教学资料。
[Abstract]:As one of the chemical sciences, and our industrial production and daily lives. The high school chemistry as one of the basic disciplines of university personnel selection, there are many knowledge points, scattered, miscellaneous, difficult to remember, easy to forget. Especially for facing the pressure of college entrance examination students, how to make complex, scattered, the knowledge system, more orderly, make the revision of chemistry in finite time is both comprehensive and practical? How to make the students really "move" to actively participate in the review, let the revision of chemistry classroom thoroughly "live"? After long-term practice of first-line high school chemistry teaching, the author found that the teaching method of "three suspected three exploration" provides an effective way for the revision of chemistry. It can promote the students more active learning, teachers "teach" more dynamic and collaboration can exercise the students The cultivation of students' ability, dare to challenge, ability of expression, from which to experience and share the joy, harvest and a sense of achievement. The senior high school chemistry teaching to cultivate the thinking way of exploring the natural chemical target is exactly the same, it is a concrete reflection of "curriculum standard >:" teachers should encourage students to cooperate with the combination of self inquiry learning style, it can make the students explore actively interested in their own activities of unity and cooperation, innovation, and enhance the overall quality. This paper exercises commentingclass senior three chemistry review as the main research object. The main content is "three suspected three exploration" the teaching method application exercises commentingclass in Wenjiang senior middle school chemistry review, and on the basis of summing up a set of suitable for the Wenjiang middle school, rich theoretical basis and the actual operation of the "three suspected three exploration of the road, the most in Wenjiang The teaching practice of high school 4,5 class of 2013 students as the research object in this paper, taking "three suspected three exploration" in chemistry review in reasonable application exercises commentingclass as the core content, and achieved satisfactory results. This paper is divided into five parts: 1. The significance and importance of the teaching method of "three suspected three exploration" in the high school chemistry review through literature research are described, and based on the initial development of the "three suspected three exploration" in the measures and methods of Sichuan province Wenjiang high school chemistry review class exercises commentingclass reasonable application of.2, the current situation of Wenjiang high school chemistry review class and grade 2013 the current high school chemistry teaching teachers were investigated by questionnaire survey and expert interviews, using self-made questionnaire to 265 questionnaires were distributed, 265 were recovered. The results showed that: (1) students in general Over reaction chemistry review existing high school teachers speak too much. (2) students are welcome "three suspected three exploration" teaching method in high school chemistry review class. (3) "incentive incentive mechanism with three suspected three exploration" teaching to the students. (4) "the three suspected three probe" used in the chemistry exercises commenting class three being widely recognized by the.3 chemistry teachers of high school, will study the teaching strategies applied to the Wenjiang high school 2013 grade 4 classes of students, and combining with the case given the actual operation process, and concluded: "three suspected three exploration" this teaching method is applied in Senior High School chemistry exercises commentingclass Wenjiang Sichuan province strongly stimulate the enthusiasm of students, so that students in a relaxed, active classroom atmosphere develop listening, positive thinking listening habits, enhance students' ability to express, to stimulate the students to dare to The question of authority innovation ability. Obviously, this will be the "three suspected three probe" reasonable application in chemical review practice reform is scientific, successful, there is a practical significance, generally accepted by teachers and students, is worth popularizing.4, through the study of this subject has formed "three suspected three exploration" in the middle school chemistry review exercises comment among test papers pingke the practical process, has accumulated abundant three chemistry review teaching materials.
