探究教学模式是新课程实施的灵魂。学生通过系列自主探究活动,才能成为课堂真正的主人,在自主实验探究活动中,学生不仅领悟科学的思维方法,更能培养创新意识和实践能力。探究教学模式的应用使教学真正成为有效教学。其中,示踪原子法无疑是探究教学中一项强有力的技术工具,它能让我们从纵多的问题假设中找到正确的结论,得到科学的本质。1943年,匈牙利人海维西(Gyorgy Hevesy,1885—1966)利用同位素作为化学研究中的示踪原子,并获得
To explore the teaching mode is the soul of the new curriculum. Students through a series of independent inquiry activities in order to become the real masters of the classroom, in the independent experimental exploration activities, students not only understand the scientific way of thinking, but also to cultivate innovative awareness and practical ability. The application of inquiry teaching mode makes teaching truly effective teaching. Among them, tracer atomic method is undoubtedly a powerful technical tool in inquiry teaching, which enables us to find the correct conclusion and obtain the essence of science from the many hypotheses. In 1943 the Hungarian Gyorgy Hevesy (1885-1966) used isotopes as tracer atoms in chemical studies and obtained
