物理化学是食科专业的必修课程,其理论在食品行业中具有广泛的应用。但物理化学理论性强、内容抽象,是学生视为最难学的课程。在教学过程中,将实例分析引入物理化学的课程,不仅能激发学生学习的积极性和主动性,还可培养学生分析问题和解决问题的能力。文章通过浅析部分章节的实例,对食科专业物理化学教学实例应用进行了探讨。 相似文献

Improving teaching and student learning in chemistry classrooms is an important goal that is constantly researched. Several comparative studies of science teaching have been carried out on different parameters, e. g. misconceptions which science teachers and students may have regarding the scientific concepts they learn and teach. Here we describe science teaching in general, and chemistry teaching in particular, in 12 countries including Israel. Different parameters are compared, including the hours that are devoted to science, the subjects included, the pedagogy, and teachers′ salaries. The survey covers all school levels: elementary school, secondary school and high school. At the high‐school level, the comparison focused on chemistry studies. In this study the variances variables, such as the hours that are allocated for science teaching, did not show an appreciable effect on students′ achievements. It was also found that, in countries where chemistry studies at the high‐school level are not mandatory, innovative pedagogies are more likely to replace the traditional chemistry teaching methods where chemistry is taught according to the structure of the subject based on basic concepts that underlie the curriculum. The study provided an additional support to the importance of the professional development of science and chemistry teachers and suggest that the autonomy that is given to them could influence the quality of science teaching and students′ achievements. 相似文献
