如何评课
一、什么叫评课?
评课就是对照课堂教学目标,对教师和学生在课堂教学中的活动及由这些活动所引起的变化进行价值判断.评课是 教学、教研工作过程中一项经常开展的活动,有同事之间互相学习、共同研讨评课;有学校领导诊断、检查的评课 ;有上级专家鉴定或评判的评课等等.评价的目的不是为了证明,而是这了改进.
二、评课的意义
评课能调动教师的教学积极性和主动性,帮助和指导教师不断总结教学经验,提高教育教学水平,提升教师的教育 教学素养;促进教师改进教学实践,使教师从多渠道获取信息,不断提高教学水平,转变教师的教育观念,促使教 师生动活泼地进行教学,在教学过程中逐渐形成自己独特的教学风格.
三、评课的原则
1.评课要坚持"以学生的发展为本",从学生全面发展的需要出发.
基础教育课程改革的核心理念是"以学生的发展为本".评课要从学生全面发展的需要出发,注重学生的学习状态 和情感体验,注重教学过程
乐高机器人走黑线设计
走黑线是时下机器人竞赛里面一个比较普及的任务,黑线是许多任务比赛里面经常会出现的,我想就这个黑线问题 跟大家来探讨一下子.
首先,单光感走黑线,这是一个比较简单的走黑线任务,也是最基本的,这里需要的是一个光感作为光值的分辨传 感器.根据黑线和空白地方的不同的光值来控制小车的不同走位.比如:小车的光感进入白色地带那么程序让小车 进入黑线,反之亦然.
小车沿黑线走
一、目标分析:
首先,分析一下你需要得到的结果:
1.速度加快;
2.沿黑线走.
二,小车必需的部件
1.马达
2.光传感器
三,如何提高各个部分的性能
1.在速度的提高上,可以采用的方法有:
1)使用齿轮或齿轮组加快速度;
2)使用较大的轮子也可获得较快的速度;
3)组合使用上面两
在伟大师父的帮助下,完成了基本的搭建.效果我还算比较满意,至少没散架,呵呵.

介绍制作乐高机器人的4个步骤
第一步:使用乐高RCX微型电脑设计机器人(硬件部分组装)
RCX微型电脑是由MIT开发的,是乐高机器人系统的核心部分.使用ROBOLAB软件及RCX,学生们可 以创造、搭建、编程真正的机器人,让它运动、做动作、甚至自己去"想".为RCX编写程序,通过各种输入( 传感器)与输出(马达与灯等)对周围环境做出响应.有多种传感器可供选择,如触动传感器、光电传感器、温度 传感器、角度传感器等.
第二步:在PC机上为机器人编写程序(软件部分让它如何动)
为RCX编写控制程序的ROBOLAB软件是一个简单、直观、易学的编程环境,tods shoes men,是以美国国家仪器公司的LabVIEW,流行于测量和自动化领域的图形化编程软件为基础开发的.ROBO LAB软件具有所有通用编程环境,如C/C++或VisualBasic等软件的功能.在计算机上为机器人编写好程序,程序一旦下载到RCX,机器 人就脱离计算机,根据程序指令,按照周围环境的输入信息来做出判断,决定下一步如何行动.完全智能化.当然 ,如果机器人未按预先设计的行动,即程序编写不
