科学探究是学生学习化学的一种主要方式,是初中化学新课程的一项重要内容。探究式教学对教师提出了很高的要求,需要教师改变观念、转变角色,由原来的化学知识的传授者变为科学探究的组织者和指导者、参与者和合作者、学习者和研究者。本人结合多年的教学实践,认识在化学探究学习中教师应作以下角色的定位。一、教师是化学探究学习的组织者和指导者化学课程中的科学探究是一个复杂的时间研究过程,它要求学生能够发现和提出问题、对问题作出合理的猜想和假设、查阅资料、收集证据、解释证据、得出结论、汇报结果并与人交流,这种学 Scientific inquiry is a major way for students to learn chemistry and is an important part of new chemistry curriculum for junior high school. Inquiry-based teaching places high demands on teachers and requires teachers to change their concepts, change roles, and change from the preacher of chemical knowledge to the organizer and director of scientific inquiry, participants and collaborators, learners and researchers . I combine years of teaching practice, understanding of chemical inquiry in the teacher should be the role of the following positions. First, the teacher is the checkers and guides of chemical inquiry learning Scientific inquiry in chemical courses is a complex time research process, which requires students to find and raise questions, to make reasonable conjectures and assumptions on the issue, access to information, to collect evidence , Explain the evidence, come to a conclusion, report the results and communicate with others
