为了让同学们更好的掌握知识,根据练习题所提供的信息,设计出了实验方案,确定了所需的器材、方法和步骤;亲自做实验,通过长时间的观察、记录,最终得出了结论。这样获得的知识,印象深刻,理解透彻。同时在学生实验设计的过程中,学生的合作意识、思维能力、科学素养都有不同程度的提高。 In order to make students better grasp the knowledge, according to the information provided by the exercises, designed the experimental program to determine the required equipment, methods and steps; personally to do the experiment, through a long period of observation, recording, and ultimately draw Conclusion. The knowledge gained in this way is impressive and well understood. At the same time, students in the process of experimental design, students’ awareness of cooperation, thinking ability, scientific literacy have improved in varying degrees.
