【摘要】 化学教师化学建模能力水平的高低直接影响着所培养学生建模能力的强弱。基于Rasch模型从模型表征能力、模型建构能力、模型应用能力3个维度开发四水平测查的《职前化学教师化学建模能力问卷调查》,对83名职前化学教师的化学建模能力进行测评,研究发现:被调查的职前化学教师化学建模能力总体较差,参照《普通高中化学课程标准(2017年版)》对化学建模能力的具体要求,分别仅有88%、42%、54%的职前化学教师的模型表征能力、模型建构能力、模型应用能力达标。因此,建议高等师范院校加强对职前化学教师化学建模能力的培养。更多还原

【Abstract】 The level of chemistry teachers’ chemical modeling ability directly impacts the strength of students’ modeling ability. Based on the Rasch model, the article develops a four-level questionnaire on the chemical modeling ability of the pre-service chemistry teachers. This questionnaire evaluates the chemical modeling ability of 83 pre-service chemistry teachers from three dimensions: model representation ability, model construction ability and model application ability. Studies show that pre-service chemistry teachers surveyed have weak chemical modeling capability overall. In the light of the high school chemistry curriculum standard(version 2017),the specific requirements of chemical modeling capability, the study demonstrates that the percentage of 88 surveyed pre-service chemistry teachers have the qualified model representation ability, however, qualified ability of model construction and application only in 42 percent and 54 percent respectively. Therefore, recommendation is put up to optimize the development of pre-service chemistry teachers modeling abilities in normal colleges.更多还原
