本研究以不同的教学处理为核心变量,采取对比实验的研究方法,探讨了采用“从宏观的定性发展到对实验现象的感性认识”和“从微观的定量发展到对实验本质的理性认识”的教学方法对小学生科学建立利用酵母菌进行发面的本质认识的影响。研究结果显示:采用“从微观的定量发展到对实验本质的理性认识”的教学方法,有利于小学生理解并掌握利用酵母菌进行发面的本质原因,同时引导学生在科学探究中通过大数据分析实验结果,展示科学规律,提高实验精度,促进实验由定性向定量过渡,使学生的认识由感性上升到理性。同时,深化学生对科学原理的理解,增强学生开展科学探究的实验意识,全面提升学生的科学素养。
In this study, taking different teaching process as the core variable, this study adopts the research method of comparative experiment and explores the use of “from the qualitative development of the macro to the perceptual knowledge of the experimental phenomena” and “quantitative development from the micro to the experimental nature Rational understanding of ”teaching methods of primary science to establish the use of yeast for nourishing the essence of the impact. The results show that adopting the teaching method of “quantitatively developing microscopically to rational understanding of experiment essence” is good for primary school students to understand and grasp the essential reasons for using yeast to make noodles, meanwhile, to guide students through scientific research Data analysis of experimental results, display scientific laws, improve experimental accuracy, and promote the experiment from qualitative to quantitative transition, so that students’ awareness from emotional to rational. At the same time, students should deepen their understanding of the principles of science, enhance students ’awareness of experiments in conducting scientific inquiry, and enhance students’ scientific literacy in an all-round way.
