1、1网络教学的不足表现在：由于学生的年龄特征、知识基础及认知能力等等限制， 学习上缺乏自觉性与自制力，加上不懂得应该学习些什么和怎样去学习，所以在广袤 无垠网络里如果没有教师的启迪与引导，很难自主地去进行学习。虽然使用计算机可 以模拟一些实验过程，但它不可能让学生真正形成实践能力。Network teaching: due to inadequate performance in students age characteristics, knowledge and cognitive ability, learning the lack of self-consciousness and se

6、ating on the surface, to acquire knowledge not reliable.二、教师尚不放心、不习惯学生的自主学习，总担心“学生自己能抓住重点吗?”、 “这个问题 他们能理解吗?”等等,而不敢大胆的放手让学生自主获取知识、 自主交流讨 论、自主探寻研究答案。 于是教师经常会采用传统的想法介入学生的学习。 The teacher is not assured, not in the habit of students autonomous learning, always worried that“ the students themselves can ho

Then the teacher will often use the traditional idea of involvement of students learning. 三、是部分学生不能熟练使用计算机和网络搜索引擎，对学习资源利用和知识信息的 获取
8、、 加工、处理与综合应用能力目前还存在一定的不足，这样影响到学习的效果。也有 部分学生受传 统的应试教育影响、 高一历史学科的地位等因素综合影响， 学生的自我探究、 发现和自主学习 能力还存在一定的缺陷，还有一小部分学生的自控力较差，浏览与课堂内 容无关的网页，甚至还 有人玩网络游戏或聊天。 Are some students not skilled in using computer and Internet search engine, to study the utilization of resources and knowledge information acquisition,

10、self inquiry, found and autonomous learning ability also has some defects, and a small part of students self- control is poor, browsing and classroom content without the webpage, even people play network game or a chat.2四、是部分教师的信息素养有待提高，仍有个别教师不会自己制作网络课件，许多工 作都请 其他老师帮忙，所制作的课件呈现方式简单，不符合学习者认知特点。此外，网络 教
11、学资源还要 进一步丰富。要进行网络教学，必须要有一套完整的网络教学资源库，如网 络课件库，习题试题 库，教案素材库等，而且要与新课程改革同步，这就需要在一线课堂 教学的教师参与网络资源库 的建设，但这些工作对教学一线教师来说，不论在时间或技术 上都存在一定的困难，这也是网络 教学对新时期教师提出的挑战。 In four, is a part of the information literacy of teachers should be improved, still have individual teachers do not produce their own network cour

15、ly high starting point, it is difficult to learn, to learn is not to understand the problems of lack of faculty time to explain, analysis easy against learning enthusiasm of students caused the failure or ineffective learning may increase.六、网络学习为学生提供了一个虚拟的、时空不限的学习环境让各个学生处在 不同的地理位 置异步学习，增大了学生之间情感淡漠和情景变异的可能性。 Network learning provides students with a virtual space, open learning environment for all students in different geographical locations of asynchronous learning, increased student apathy and situational variation possibilities.
