在化学教学中,我们可以根据不同的教学内容,采取不同的思维训练方法,以达到激活学生思维的独创性、灵活性、深刻性和批断性之目的。1.利用直觉思维,培养思维的独创性。近几年来我根据新教材的特点,用探索法,让学生自己做,自己去发现规律,掌握知识,充分培养学生思维的独创性。例如:在“原电池”一节课中,我将“课堂”变成“学堂”,将这节课分成四个阶段:(1)引入阶段:首先从锌跟稀硫酸反应的电子转移入手,提出“化学能能否转变为电能”引入课题。
In chemistry teaching, we can adopt different methods of thinking training based on different teaching contents to achieve the purpose of activating students’ originality, flexibility, in-depthness, and decision-making. 1. Use intuition thinking to cultivate the originality of thinking. In recent years, according to the characteristics of the new teaching materials, I have used the exploratory method to allow students to do it themselves, to discover the laws themselves, to acquire knowledge, and to fully cultivate the originality of students’ thinking. For example, in the “primary battery” class, I changed “classroom” to “school” and divided this class into four phases: (1) Introduction: First, start with the electronic transfer of zinc and dilute sulfuric acid reaction. Proposed the introduction of the issue of whether chemical energy can be converted into electrical energy.
