培养学生的自学能力,是中学化学教学的重要任务之一。近两年,就教学中如何培养学生的自学能力,进行了一些试验。一、试验的基本情况1981年,我担任高一新生的化学课,为了加强学生自学能力的培养,就锐意改变传统教法。每一节课总让学生先阅读教材,然后根据教材的重点、难点,并结合学生在阅读中提出的问题,进行启发、讨论、精讲、练习等。例如,学习“气体摩尔体积”这一节,上课时,当引出课题后,就要同学先把教材阅读一遍。学生看书时,我就在黑板上出了四个思考题:①1摩尔固态物质或液态物质的体积是否相等?为什么?②在标况下,1摩尔任何气体的体积是否相同?为什么?③1摩尔气体是否只有在标况下才占有22.4升?④在一定的温度和
Cultivating students’ self-learning ability is one of the important tasks of chemistry teaching in middle school. In the past two years, some experiments have been conducted on how to cultivate students’ self-learning abilities in teaching. First, the basic situation of the test In 1981, I was a freshman chemistry class, in order to strengthen students’ self-learning ability, they are determined to change the traditional teaching method. In each class, students are required to read the teaching materials first, and then inspire, discuss, elaborate, and practice according to the key points and difficulties of the materials and the questions raised by the students in reading. For example, to learn about the “gas molar volume” section, when the class is introduced during class, students must read the teaching materials first. When students read books, I have four questions on the blackboard: 11 moles of solid or liquid substances are equal in volume? Why? 2 Under normal conditions, 1 mole of any gas is the same volume? Why? 31 Moles of gas Does it only occupy 22.4 liters under standard conditions? 4 at a certain temperature and
