This paper designed an inquiry activity, which led the students to learn the modification of calixarene using knowledge of common functional groups of organics, and explore a kind of pH-switchable bis-calix [4] arene polymer capsule with the aid of hydrogen bond. The aim of this activity was to help senior high school students understand better about the idea of "structures determine properties", deepen students' understanding of properties of compound according to characteristics of functional groups, and make students realize how to design molecules based on application requirements.

The clear process structure is one of the high qualities of classroom teaching. Opening, developing, changing and concluding are four steps of writing an essay. Just like writing, classroom teaching also needs to design these four steps based on the logical relationship of knowledge which can make the whole teaching procession all linked with one another and promote the construction of the cognitive structure.

Using the related phenomena after students often have carbonated drinks in daily life as context, this paper designed the review teaching of ionization and hydrolysis equilibrium based on construction of big ideas, realized the reality of life context, and improved the effectiveness of chemistry teaching.

Through questionnaires and interviews, this paper investigated the conceptions and behaviors of senior high school chemistry teachers to chemical experiment teaching, and the status of teaching resources in Yangpu district of Shanghai. The results indicated that the teachers well recognized the role of experiment in chemistry teaching, but they didn't strengthen corresponding teaching behaviors in teaching practice; the experimental resources of the schools were unbalanced with some schools lack of experimental resources. This study analyzed the causes of these phenomena, and gave some suggestions on strengthening experiment teaching and improving relevant ability of teachers.

This paper improved the experiment of alcohol detection from qualitative to quantitative by chromaticity sensor, as an example for application of sensor technology in chemical experiment teaching in senior high school. The chromaticity sensor provided real-time and intuitive data, expanded the application of chemical principles in life, broadened the view of students, and developed the innovative consciousness of students.

Reduction of vapor pressure of dilute solution can be confirmed by a simple experiment and explained from microscopic perspective in the article. The combination of experimental phenomena and theoretical explanations can help students understand properties of dilute solution better.
