近年来,以实验(或生活)中发现的意外现象为素材的化学探究性试题倍受青睐,十分走俏.这种试题选材于实际情景,以学生在实验(或生活)中发现的意外现象作为探究新知的起点,引导学生对发现的问题展开深层次的探究,不仅学到了知识和方法,更增强了探究意识.这样的试题把问题求证的过程作为探究学习任务,对学生充分发挥探究及创新能力留有广阔的空间.例1 甲、乙、丙、丁四位同学在探究碱溶液与酚
In recent years, chemical inquiry questions based on unexpected phenomena found in experiments (or life) have become popular and very popular. These questions are selected in actual situations and are based on unexpected phenomena discovered by students in experiments (or life). Exploring the starting point of new knowledge and guiding students to conduct in-depth exploration of problems found, not only learned knowledge and methods, but also enhanced the sense of inquiry. Such questions take the process of question verification as the task of inquiry learning and give students full play of exploration and innovation. Ability to leave a vast space. Example 1 A, B, C, Ding four students in the exploration of alkali solution and phenol
