Based on high school chemistry knowledge such as chiral molecules, intermolecular forces and hydrogen bond, an instructional material about the basic principles of chiral separations of the ephedrine-pseudoephedrine (E-PE) isomers by GO-coated capillary electrophoresis was designed, in order to extend high school chemistry.

In order to understand the domestic research hotspot in high school chemical experiment and learning, provide strong support for future research of school chemical experiment and learning. This study used bicomb1.0 and IBM SPSS20.0, retrieved 518 articles about experiment and chemistry learning from 2001 to 2013, and drew mapping knowledge domains. The results showed that domestic research on high school chemistry experimental learning involved four main areas: chemical experiments in new curriculum of high school promoted chemical knowledge, learning, quality education, innovation, observation and other ability; high school chemistry experiments stimulated students' interest and cultivated students' ability; in classroom teaching, experiments teaching with multiple media teaching such as teaching mode reform and innovation promoted the quality of teaching; miniaturization and greening of chemical experiment strengthened students' ability.
