物理是一门以实验为研究基础的学科。对于物理教学,必要的验证和演示实验有助于学生物理观念的形成,有助于培养学生崇尚科学、崇尚实践、尊重客观事实,追求真理的辩证唯物主义世界观。在盲校的物理教学中,有很多的困难。由于学生的视觉缺陷,对自然现象和生活常识没有充足感官体验,还有无法获得全面的物理数据,无法定量分析,也不能自己控制和操作实验。这使得他们在学习物理知识过程中,对物理现象不能认识,对物理原理一知半解,对物理规律不能理解,结果往往是失去了学习热情和学习兴趣。
Physics is a discipline based on experiments. For physics teaching, necessary verification and demonstration experiments are conducive to the formation of students’ physics concepts and help students develop a dialectical materialist worldview that respects science, advocates practice, respects objective facts, and pursues truth. There are many difficulties in the physics teaching of the blind school. Due to students’ visual defects, there is not enough sensory experience for natural phenomena and common sense of life, and there is no way to obtain comprehensive physical data, which cannot be quantitatively analyzed, nor can one control and operate experiments by himself. This makes them unable to understand physical phenomena in the process of learning physics knowledge. They have little understanding of physical principles and cannot understand the laws of physics. The result is often lost in learning enthusiasm and interest in learning.
