新编义务教育《生物》第二册(人教版)“人体生理卫生”部分,共有9个演示实验、12个学生实验和4个实习项目。我认为加强了实验教学是新编教材一个显著特点,这样做既是本学科教学特点的需要,更是培养21世纪人才素质的需要。通过实验教学,既可以提高学生动脑动手能力,还可以培养他们实事求是的科学态度和探索精神。在教学实践中,在认真做好演示实验的同时,重点应突出指导学生做好实验,以保证实验课质量。根据新教材的特点,结合一期来的教学体会,在实验教学中,就时序而言,对实验要加强三步指导。 The newly edited Compulsory Education “Biology” Volume II (PEP) “Human Physiology and Health” section, a total of 9 demonstration experiments, 12 student experiments and 4 internships. I think that strengthening experimental teaching is a distinctive feature of new textbooks. This is not only the need for the teaching characteristics of the subject, but also the need to cultivate the talents of the 21st century. Through experimental teaching, students can not only improve their brain activity, but also cultivate their scientific attitude and exploration spirit of seeking truth from facts. In teaching practice, while doing a good job of demonstration experiments, the emphasis should be given to guiding students in doing experiments to ensure the quality of experimental courses. According to the characteristics of the new teaching materials, combined with the teaching experience in the first period, in the experimental teaching, in terms of timing, it is necessary to strengthen the guidance of the experiment in three steps.
