在新课程理念的指导下,中学物理教育既要让学生学习系统的物理知识与技能,又要训练学生科学的思维方法.这就要求教师在新课程教学中多用探究式和发现式的教学方法,倡导学生积极主动地参与教学过程,勇于提出问题,学习分析问题和解决问题的方法,在实践中学习.如2012年黄石市中考实验操作考试中有这样一道试题.如图1,用一块电压表测电源电压,闭合开关后读出电压表的示数U,并记录下来.U=.(实验电源用两节干电池串联组
Under the guidance of the new curriculum philosophy, the physics education in middle school should not only let the students learn the system’s physical knowledge and skills, but also train the student’s scientific thinking method, which requires teachers to use inquiry-based and discovery-based teaching methods in the new curriculum teaching , Advocate students to take the initiative to participate in the teaching process, the courage to ask questions, learn to analyze and solve problems, learn in practice, such as the 2012 Huangshi test operation test has such a test questions shown in Figure 1, with a voltage Table measuring supply voltage, switch the voltage meter after reading out the show the number of U, and recorded. U =. (Experimental power supply with two dry cell series group
