摘要:采用美国诺尔曼·莱德曼(Norman G. Lederman)和朱迪斯·莱德曼(Judith S. Lederman)编制的科学探究观(View About Scientific Inquiry, VASI)调查问卷,对38位职前化学教师的科学探究观进行了调查。结果发现,职前化学教师对科学探究的理解水平参差不齐,理解水平最好的是维度三(D3),74%的职前化学教师对该维度持“通晓的(Informed)”观点;理解水平中等的是维度二(D2),66%的职前化学教师对该维度持“混合的(Mixed)”观点;理解水平最差的是维度七(D7),61%的职前化学教师对该维度持“朴素的(Naive)”观点,并且没有人对该维度持“通晓的”观点,针对这种情况,提出3条改进策略:一是“显性化”,在课程标准和教科书中以“显性”的方式呈现有关科学探究理解的内容;二是“活动化”,教师在教学中设计并实施基于理解探究的各种实践活动;三是“反思性”,引导学生积极主动地反思科学探究活动,获取对科学探究的深入理解。
