新课程标准强调 ,培养学生的科学素养是课程改革的根本性目标 ,而积极开展科学探究是实现这一课程标准目标的关键。现以一个化学计算中常出现的问题来例说。一、创设问题情境问题一 :相同质量的钠、镁、铝、锌与足量的酸反应 ,哪种金属制得的H2 最多 ?学生讨论、计算并发表观点 The new curriculum standards emphasize that cultivating students’ scientific literacy is the fundamental goal of curriculum reform, and actively conducting scientific inquiry is the key to achieving the standard goals of the curriculum. Now an example of a problem that often occurs in chemical calculations. First, create a problem situation Question 1: The same quality of sodium, magnesium, aluminum, zinc and a sufficient amount of acid reaction, which metal made H2 up to students discuss, calculate and publish their views
