Keywords: inorganic chemistry experiment teaching students' quality improvement
With the continuous development of science and technology, the society needs more and more chemical talents with strong comprehensive ability and innovative spirit. Because chemistry is a subject based on experiments, it is particularly important to play the role of experimental teaching in cultivating students' comprehensive quality. Cultivating students' comprehensive quality through chemical experiment teaching is one of the central tasks of chemical experiment teaching. In recent years, chemical educators have done a lot of exploration and research on how to cultivate students' comprehensive quality in experimental teaching, and achieved fruitful results. However, there are still many problems in actual teaching, which makes the experimental teaching fail to achieve the goal of cultivating students' comprehensive quality. In view of the outstanding problems in inorganic chemistry experiment teaching, the author mainly discusses the methods of cultivating students' comprehensive quality in inorganic chemistry experiment teaching from the following aspects.
1 Persist in keeping pace with the times and update teaching concepts.
The teaching idea of keeping pace with the times is the key factor to realize the teaching goal in the teaching process. According to the training objectives and basic requirements of teaching in the new period, in order to adapt to the curriculum reform in the new period, we should actively absorb advanced teaching concepts, take improving students' quality as the standard, take teaching quality as the center, take application as the purpose, take "necessity and sufficiency" as the standard, focus on the reform of curriculum system, teaching content and teaching methods, and achieve the goal of strengthening students' basic quality, practical ability and vocational skills by reforming examination forms. Break the boundaries of the subject-based model, make the teaching content connect with each other, avoid duplication, pay attention to integrating theory with practice, and highlight the effect of practical skills training.
2. Carry out design experiments to cultivate students' innovative ability.
On the basis of students mastering basic operations, design experiments are introduced to encourage and urge students to think independently, observe phenomena and analyze problems. Encourage students to design an experimental scheme according to the theoretical knowledge they have learned, explore the feasibility of the scheme, and further improve it in the experimental process. This method can greatly arouse students' initiative and enthusiasm in learning, stimulate students' spirit of exploring knowledge, and design experiments also have great advantages in improving students' innovative ability.
3. Select the experimental content and update the experimental teaching system.
Inorganic chemistry experiment occupies a special position in chemical experiment teaching, and it is the first experimental teaching course for students' chemical experiment education. Students' interest and learning attitude will directly affect the overall effect of chemical experiment teaching in the future. In the traditional inorganic chemistry experiment, the content of elemental chemistry experiment is too much and the form is mechanical, which greatly reduces the interest of students and the freshness of college chemistry experiment education. At the same time, the implementation of the leading idea of experimental teaching quality and skill training in the new period is difficult to realize in the current single system of inorganic chemistry experiments. Therefore, it is particularly important to integrate the experimental contents of inorganic chemistry and construct a new experimental system.
In the process of updating the experimental system of inorganic chemistry, we must pay attention to the urgent reform of elemental chemistry experiments. In the new era, college education has put the cultivation of students' comprehensive quality in an important position, and the chemical experiment system has also undergone great changes. In the basic chemical experiment, the copying operation and skill training of chemical experiment have become the main line, but the historical position of the experiments on the properties of elements and their compounds has been questioned. Some are greatly compressed, and some are simply discarded. It can be said that the reform of elemental chemistry experiment is one of the key points in the reform of university chemistry experiment system. The author thinks that the reform of elemental chemistry experiment is not simply to abandon the content of elemental chemistry experiment, but to choose the answers that are conducive to students' self-summing, which are few and precise, and do not stick to the systematicness of classroom teaching content, abandon the previous teaching material compilation method of elemental chemistry experiment, and adopt the method of enumerating experimental points but not enumerating reagents and writing experimental steps, so that students can complete the experiment and write reports as required; In addition, the basic chemistry experiment should also adopt open teaching. Only the main points and tips of the experiment are given in the experimental teaching materials, and students can choose the experimental content at will according to their own interests, and complete the least experiments and experimental reports in a given time. This is more conducive to the cultivation of students' innovative ability.
