This study analyzed the differences of chemistry experiment teaching in junior and senior high school with example of "experimental methods for study matter" in senior high school textbook, and put forward four teaching strategies to achieve the effective connection of chemistry experiment teaching between junior and senior high school, such as guiding students to form good experimental habits, choosing reasonable teaching methods according to the actual level of students, grasping the differences of convergence points to guide students to break through the thinking barrier, and strengthening experimental ideas, and so on.

This study discussed that the school-based selective courses could really make a difference through integrating the subject resources, teacher resources, and local resources, and developing and implementing systematic, hierarchical and diversified school-based selective courses which coordinated with the national curriculum.

This paper defined the concept of the coverage rate of note taking, and detected the correlations between the chemical class notes and the academic performance, note-taking habits and the academic performance, synthetic variables and the academic performance. And according to the results of the test, this study put forward some teaching suggestions to help students to do good class notes in order to improve the learning ability.

This paper discussed the teaching design of salt hydrolysis through comparing acid-base ionization theory and acid-base proton theory, expounded selecting high school knowledge of natural growth as teaching resources to help students to form chemistry concept and cultivate students' understanding ability and scientific thinking skills, in order to affirm the possibility of reducing students' learning burden by adding teaching materials.

In view of the current problems of teaching design based on learning plan, this study discussed that letting learning plan design integrate into teaching plan design from the perspectives of optimizing the integration of teaching system, developing teaching design of teaching-learning as an organic whole, in order to achieve the "elaborat presupposition" requirements of teaching design.

Through investigation, this paper showed that students' answers to optional items of college entrance examination of chemistry was related to four factors: chemistry elective courses that school opened, difficulty of test items, time needed to answer questions and students' learning ability. It was suggested that school should open enough elective courses and allow students to show their own selectivity, so as to meet the idea of multi-module with optional courses of new curriculum and the core concept of "all for each student's development".

The knowledge about student was an important component in the PCK (pedagogical content knowledge) and necessary to implement effective teaching. This study investigated senior high school chemistry teachers' knowledge about students in redox reaction teaching. The t test about independent sample, single factor variance method and monadic linear regression analysis method had been used to deal with the data. The results showed that teachers' gender, teaching age, educational background had significant influence on the knowledge about students; the dimensions of learning basis, process and result had different level of effects on the knowledge about students. And some suggestions in view of the conclusion had been proposed.

This paper developed chemical affection scale for senior high school students through literature and questionnaire survey, the factors were analyzed and named by exploratory factor analysis with SPSS 21.0 software, and the internal structures of scale were tested by confirmatory factor analysis with AMOS 21 software. Internal consistency, Rulon split half reliability and correlation test showed that the scale had high reliability. The correlation coefficient between item and index, structural equation model fitting analysis illustrated that it had high validity. Through large-scale testing, effective and reasonable results showed that the scale could be used as an assessment tool to evaluate the chemical affection of senior high school students.

"Ion" is a very abstract chemical concept, belonging to key and difficult point in junior 3 chemistry teaching. This paper set the teaching situation for pictorialization of the abstract knowledge based on the information technology, taking the formation process of sodium chloride as an example, showed the application of situation in "ion" teaching.

To explore the effect of different silver coordination compounds on silver mirror reaction, this paper used aqueous ammonia, ethylenediamine, potassium rhodanate, and methylamine as ligands, and used the stability constants of different silver coordination compounds to study the silver mirror reaction under different temperatures, compared the formation time of silver mirror and its quality. The results indicated that silver coordination compound with ethylenediamine as ligand had higher stability constant and stronger alkaline, and high quality silver mirror could form quickly at room temperature, thus it was suitable for classroom teaching of silver mirror reaction experiment.
