Quality education is the trend and mainstream of current education reform. The implementation of quality education should run through the classroom teaching of specific subjects, and classroom teaching is the key and main channel to implement quality education. First of all, only by changing the teaching concept can we reform the teaching mode and optimize the classroom design through the application of multimedia information technology. Taking students' learning as the center and conforming to the teaching law and students' cognitive law as the premise, rational selection of multimedia can greatly exert its advantages, which is conducive to the implementation of quality education and cultivate students' memory and thinking abilities.

First of all, the author expounds what is quality education and the role of multimedia technology. Then, it specifically analyzes the role of multimedia-assisted teaching in promoting quality education:

Proper use of multimedia can cultivate students' active learning ability. This is reflected in two aspects. First, teachers design, make or choose multimedia courseware suitable for teaching content and teaching objects, which organically runs through their teaching goals and learning-oriented teaching ideas; Second, in the process of watching multimedia courseware, students' brains can be stimulated to review and reproduce the original or learned knowledge, and creatively use the old knowledge to learn new knowledge, and at the same time stimulate their interest, curiosity, memory and emotion in new knowledge, thus generating the desire for active learning. The author cited the multimedia courseware of "meiosis" and "homologous chromosomes" in biology teaching to illustrate this point.

Multimedia environment can effectively promote memory and cultivate memory ability. Multimedia integrates pictures, words, sounds, images and other stimuli, which makes students' vision and auditory pathway in a state of excitement, and relevant knowledge will leave a deep impression on their brains. Multimedia conforms to the process of human memory. Multimedia shows the connection of knowledge space, systematizes knowledge and forms a network, which is beneficial for students to compare, process and summarize knowledge and form a memory based on understanding.

Multimedia-assisted teaching is helpful to cultivate students' analytical and inductive thinking ability. Multimedia teaching is convenient to provide students with knowledge materials, and each student can build a knowledge system according to his own cognitive structure, which provides great convenience for teachers to change "conclusion teaching" into "process teaching". The author uses the teaching of breathing method to illustrate this point.

Multimedia-assisted teaching is helpful to inspire innovative thinking and cultivate innovative ability. Multimedia-assisted teaching can optimize classroom design, give full play to students' dominant position, create a democratic, harmonious and equal atmosphere, facilitate the mobilization of students' learning enthusiasm and give full play to students' dominant role, thus enabling students to establish innovative consciousness and improve their innovative ability. The author uses the teaching of "the discovery of photosynthesis" and "the discovery of auxin" to illustrate this point.

The author's analysis has been thorough, and what I feel most about multimedia is that it can improve the efficiency of class. Because teachers don't have to write books on the blackboard in class, they can save a lot of time. However, for students, it is still necessary to concentrate on taking notes carefully, because they will miss notes carelessly, so they will not be absent-minded. If you really miss the content, you can watch it after class. Another point is that students should listen and write while watching. As the saying goes, you have to pay attention to all directions. Therefore, the whole class process must be highly focused. But some courseware is too vivid, which will distract students' attention. For example, some teachers put a lively little animal in some corners, which has nothing to do with classroom teaching. Although it can stimulate students' interest, it is easy to have a negative impact. Therefore, the rational use of multimedia teaching is very necessary. Therefore, the more multimedia is used, the better the effect. Teachers should choose multimedia according to students' cognitive rules and characteristics, so that multimedia can become a tool to inspire students' cognition and thinking, rather than a tool to display teaching content.
