Teaching Implementation and Improvement Direction of Student Science Experiments -- Take Weigh the Mass of Solids with a Balance for Example

Abstract

This article explores how to optimize the teaching design of the measurement experiment Weighing the Mass of Solids with a Balance in the context of the new middle school entrance examination, aiming to enhance students physical experiment operation ability and innovative thinking ability. The article points out that experimental teaching should combine the requirements of textbooks and new curriculum
standards, pay attention to the design of experimental operation details, and stimulate students interest in scientific exploration through problem driven strategies. Specifically, in the chapter on Measurement of Quality, the knowledge sequence of the textbook includes the concept
of quality, unit conversion, quality attributes, measuring instruments, and the use of scales. In teaching, it is necessary to pay attention to the
initial use of scales, guide students to understand the structure and principles of scales, and attach importance to experimental operation training. In response to teaching difficulties, such as error analysis, measures should be taken to improve students understanding, such as through
example analysis and strengthening guidance on experimental steps. In addition, the article also emphasizes the direction of teaching improvement, including adjusting the content position to optimize the learning process, segmenting teaching based on student learning situations, optimizing teaching methods, adding experimental report writing, encouraging communication and display, designing multi-level experimental
tasks, and promoting the spiral increase of students scientific exploration ability through repeated experiments and problem guidance.
