Microcosmic Study On The Formation Process Of 'Inter-Particle Forces' Conception

'Inter-particle forces'conception is the core of chemistry study. Because the abstract concept, students have difficulties in learning the concept. As a result, it is difficult for students to understand'Inter-particle Forces'conception.'Inter-particle forces'conception is chosen to become the research topics.The empirical research conducted in three areas:1. Exploring students''inter-particle forces'preconception, before learning 'inter-particle forces'conception;2. Studying the conceptual formation of students''inter-particle forces'conception, during studying chemistry bond conception;3. Exploring students''inter-particle forces'misconception, after finishing learning ''Inter-particle Forces'Conception;By the analysis of quantitative and qualitative data, come to the following conclusions:There is a variety of'inter-particle forces'preconception in students'mind; Wrong'inter-particle forces'preconception and discontinuous teaching become an obstacle to make students understand the concept; Because students cannot fully understand'inter-particle forces'concept, there is a lot of'inter-particle forces'misconception in the application level.
