Introduction
Online courses are vivid and interactive. The use of photoshop software to assist teaching in the teaching process is conducive to improving learning efficiency and improving students' practical ability. The design and development of online courses have promoted the progress of teaching ideas, teaching methods and teaching methods, thus promoting the reform of teaching mode in the network teaching environment.

Progress in the construction of university online courses
University online courses are mainly for learners with a certain knowledge base or strong selflearning ability. And for learners, the content design of online courses should reflect a certain degree of autonomy and collaboration. Web-based courses are the main direction of university network course construction, that is to say, network courses are realized through the Web as the transmission channel, which is beneficial to the sharing of educational resources.
At present, great progress has been made in the construction of university online courses. From the overall design point of view, online courses combine the characteristics of various disciplines, closely follow the forefront of academic development, and refer to excellent textbooks. Whether it is modules, content, or technologies used, they are more in line with teaching needs, and the course content covers a range of Very broad, scientific, rigorous and pedagogical. In terms of teaching resources, online courses include a wealth of materials and information, and effectively integrate a large number of reference materials such as literature and learning resource websites, so that the course text can be up to millions of words, and the course production can include hundreds of thousands of videos. Animation. In terms of teaching technology, online courses can mobilize learners' multiple senses, usually in forms, pictures, PPT, 3D animation, video and other forms, to intuitively and vividly present teaching information, so as to deepen learners' understanding of knowledge content impression. Photoshop online course, it can be used as a beneficial supplement to traditional classroom teaching, and can be combined with traditional classroom teaching, and most of the teaching and operation exercises can be achieved through online courses. The use of online courses to assist traditional course teaching has achieved good teaching results.

The advantages of optimizing university online course teaching through photoshop
The introduction of network-assisted teaching in teaching is a requirement of resource-based learning mode. Constructivist learning theory believes that students are the main body of information processing. Only by providing students with multi-faceted and rich autonomous learning resources can it be beneficial for learners to construct their own knowledge system. As a huge resource library, the Internet provides massive new resources every day. In this case, the traditional classroom teaching mode is not enough, and resource-based learning has become a useful supplement to the traditional teaching mode.
A very important role in the network-assisted education system is to build a resource-based learning environment for students. There are many Photoshop resources on the Internet, which is unmatched by traditional teaching materials. The rich resources can better provide the information needed to solve the problem. Therefore, teachers must browse some Photoshop related websites.
Although the Internet provides a large number of resources, resource-based learning is not a blind and aimless wandering in the sea of information. How to use network information resources efficiently has become an important issue of resource-based learning. Therefore, universities should sort, choose and classify related resources such as classic and excellent tutorials and skills on the Internet, and include them in online courses, and accumulate the most direct and profound experience from them, so as to be targeted in the teaching process. See Figure 1. Students obtain excellent Photoshop resources through online courses. Such online courses can not only fully reflect the "navigation" role of teachers, but also reduce students' blindness in searching for resources online and improve learning efficiency. At the same time, these excellent resources are sorted, selected and classified by teachers, which not only integrates teachers' grasp of teaching material design, but also penetrates the rich information of network resources. Excellent resources revolve around textbooks. In the process of classroom analysis and guidance, teachers share and show the excellent resources they need to students, attracting students' attention and increasing their interest. The excellent resources provided on the website can not only strengthen the operation methods and skills of students to learn Photoshop software, consolidate the learning results, but also improve their practical ability. In this way, the classroom effect is undoubtedly much improved than that of traditional teaching, so as to realize the optimization of traditional classroom teaching.

Application measures of photoshop software in university online courses
A. Construction goals of the Photoshop online course The main purpose of the Photoshop course is to cultivate students' ability to draw, process and comprehensively create graphic images, and to improve their aesthetic ability, innovation ability, design ability and teamwork ability. The construction of online courses mainly relies on the Deshi network teaching platform of the college to meet the teaching needs of Photoshop courses, facilitate students to learn and practice independently, and assist and promote the reform and experiment of teaching modes such as blended teaching and flipped classroom.

Basic operation and application of Photoshop image processing software, dig deep into the hidden skills behind these tools, and help students form unique thinking concepts in the process of learning to make graphics. Knowledge of relevant image processing, able to skillfully use software for standardized design and deal with problems actually encountered in life.
The design of teaching content. According to the teaching objectives, the following online course teaching contents are determined: Photoshop basic theory, selection and editing of selection area; Photoshop image editing, image tools and drawing; Photoshop image color and tone adjustment, layer application and editing; path; channel and masks; filter effects. Build a knowledge point system according to the teaching objectives, refine the teaching content of the first chapter, and organize the teaching content.
Design of teaching strategies. In the teaching process, it is necessary to play the leading role of teachers and emphasize the main role of students. Therefore, in the design of teaching strategies, universities mainly use case teaching method and task-driven method to organize teaching activities. Case teaching method is a kind of teaching method. The method of using cases to teach. In the teaching process, it is required to take the actual case as the object to be analyzed according to the requirements of the syllabus. Under the leadership of the teacher, the teacher and the student should jointly participate in the case analysis, discussion and finding ways to achieve it. Work. The case teaching method is extremely beneficial for stimulating students' interest in learning, cultivating students' creativity, hands-on ability, and analysis and problem-solving abilities. See
