浅谈生物实验在高中生物教学中的重要性

1、浅谈生物实验在高中生物教学中的重要性生物学是一门实验科学。只有重视观察和实验，才能适应科学技术的高速发展，才能培养出全面发展的人才。生物实验在生物教学中的重要性主要有以下几个方面：（一） 有利于学生加深理解和巩固掌握所学的基础知识在实验中通过对实物的观察研究，能增强学生的感性认识，帮助学生巩固概念，深化对原理、规律的理解，并且有助于学生掌握探究生物学知识的方法。 （二）有利于培养学生生物实验操作技能重视对学生进行生物学基本技能的训练，是中学生物学课程标准规定的教学要求之一。大纲要求学生学会使用显微镜、放大镜等仪器；学会制作临时装片、徒手切片、解剖小动物、采集和制作生物标本的方法；学会做简单的生

2、理实验；学会绘制生物图等技能。这些技能只有在实验中反复练习，才能学会和熟练掌握。（三）有利于培养学生的观察能力、思维能力及分析问题和解决问题的能力实验是手脑并用的实践活动，是培养学生观察能力最直接、最有效的途径，可透过现象抓住事物的本质，分析问题的因果关系，找出解决问题的一些方法和措施。实验在一定程度上是模仿科学研究的过程，是一种基本的科学研究方法。探究性的实验教学以及开展论文联盟整理实验设计的活动对培养学生提出问题、做出假设、设计实验、观察记录 、分析推理等多方面的科研能力是十分有利的。( 四)有利于培养学生严谨的科学态度和认真细微的学习习惯生物实验本身具有严密的科学性,只有正确的实验方法和

3、实验步骤,才能达到预期的目的.因此在实验中,教师要严格要求学生按操作规程认真做实验,仔细观察实验现象和完成实验作业,不怕困难和失败.只有这样,才能使学生逐步树立严谨的科学态度,养成认真仔细的学习习惯.（五)有利于培养学生学习的兴趣及调动学生学习的积极性生物实验是形象和直观的,学生通过实验看到了自己平时看不到的生物微观世界,看到了平时见不到的生理过程和生理现象,并且这些都是在自己的努力下,亲自观察和体验到的,因此,会十分兴奋和感兴趣,大大地调动了学生学习生物的积极性. (六)有利于培养学生团结协作的精神由于现代科学的发展和各学科之间互相渗透,在科学研究等领域要求科学家、科研人员之间必须有相互协作

4、的精神.学生实验往往以小组为单位进行,这有助于培养他们团结协作的精神。总之，生物实验对于培养学生学习生物学的兴趣、加深理解生物学的基础知识或直接获取生物学知识、掌握实验基本技能、培养学生的能力都有重要作用。因此，在高中生物教学中必须引起高度重视。 tgz7r4i30ka1dkaghn3xtkknbycudxqa7fhyi2chhi92tgkqcwa3ptgshls50clmtwn60eo8wgqv7xav2ohum32wgeauwydiawgmer4i30ka1dkaghn3xtkknbycudxqa7fhyi2chhi92tgkqcwa3ptgz7r4i30ka1dkagtgk tgz7r4
