This paper focused on organic compounds, constructed composition model of chemistry discipline core literacy and performance expectations, revealed the development of chemistry discipline core literacy, and constructed learning quality level. Then this study developed assessment tool based on Rasch model, explored the performance of learning quality and chemistry discipline core literacy in organic compounds under the current curriculum and teaching. It contributed to the organic compounds instruction of improving chemistry discipline core literacy.

This paper is a case of high school organic chemistry teaching in the background of the new curriculum standard guided by competences development and the theory of project based learning.The project focuses on exploring the mysterious medical adhesives, functional oriented structural design and synthesis are main project learning activities.This paper presents the teaching design and practice process of module review by project learning, summarizes the ideas and strategies of theme demonstration and determination, activity planning and design, context material selection and presentation, provides reference for teachers to carry out project teaching practice.

This paper designed and implemented a literacy-oriented project teaching:Exploring the Magical Medical Adhesives. From the perspective of teachers' behavior, analyzed the project teaching video by coding, and three key processes, seven types of high-frequency behaviors, and seven types of high-frequency and secondary-high frequency problems were identified. Watched the video again based on the coding results, this paper discussed how teachers could help students obtain cognitive perspective and paths through high-frequency behavior types, high-frequency and secondary-high frequency problem types in this project to help the development of students' chemistry discipline core literacy.

Taking teaching design and implementation of "experimental inquiry on walnut cake baking recipe" as an example,this paper discussed the process of the teaching to promote "deep learning" from the selection of context material,the design of classroom questions,the determination of classroom tasks,the design of learning activities and continuous evaluation program and so on.

Taking the chemical reaction principle of water purification by alum as an example,this paper focused on analyzing the seven teaching connections in "chemistry 1" for high school,and then briefly introduced the teaching connection in two elective modules "Chemistry and Life" and "Principle of Chemical Reaction". Using mind map,model diagram,concept map,flow chart and other graphic thinking teaching methods,we could carry out knowledge linking teaching,which was helpful to strengthen students' subject understanding ability and cultivate their chemical core literacy.

The aim of this study was to investigate how 561 grade 10^th students from six different senior high schools in Guangzhou learn oxidation-reduction reaction by applying Knowledge Space Theory. The result showed that:(1) Students from different schools had learning difficult in core knowledge. Significant differences were found in the scores of different schools. (2) Large differences in the numbers of knowledge state and the structure of knowledge space were found. (3) Some school students' critical learning paths were similar to expert's critical learning path, but the others were not. This paper also discussed the method of applying knowledge space theory to promote high school students to study scientific principles.

Exploring the effect of concentration on a reaction rate is a classic foundation experiment in both China and overseas. The experiments have the similar content while the teaching methods are quite different. The teaching cases of China tended to reach the chemistry conclusion by experiments simply,while those of Britain and America focused on the procedure and method of the experiment:designing the controlled variables,statistically analyzing the data with plotting graphs,emphasizing on the post-experiment procedure and consolidating the behavior process of experiment teaching in evaluation.

This paper improved the ammonia fountain experiment device,optimized the amount of reagent,and integrated the ammonia generation and fountain experiment,so that its operation was simple,the experimental success rate was high,and could be completed within 3 minutes.

This paper made a three-chamber gas double-fountain experimental device by organic glass using acetone as binder,which integrated gas collection and fountain experiment. The experiment could be performed in a simple way with more obvious phenomena. In addition,it was a multi-function experimental device and could be used for verification of gas property.

The complexing reaction of Fe³⁺ and SCN^- was sensitive and the color change was obvious. Considering the transition of high school teaching,this paper focused on the use of Le Chatelier's principle,analyzed the effect of concentration on the color reaction from 3 aspects,such as redox reaction,changing the pH of solution,adding other coordination ions and so on.

In the national high school chemistry competitions, organic chemistry has always been an important part of the competitions, which is quite difficult. Therefore, based on analysis of the questions in the national high school chemistry competitions, this paper expounds the learning methods of three modules:elementary organic reactions, theories in organic chemistry, reaction mechanisms, and also summarized the solution methods of induction, backstepping and comprehensive analysis to help students improve competition performance within a short period of time.
