"The great rejuvenation of the Chinese nation is a relay race, which needs generations to continue to struggle for." Recently, Professor Zhao Qiancheng, vice president of Hunan University of Science and Technology and head teacher of Class 1, Grade 2021 Mathematics, taught students the special party lesson of "Striving for the Youth Track, Absorbing the Great Power of Building Dreams" to help pilot the training of "Dream Space" talents. How to cultivate and bring up the new generation worthy of the national responsibility and strive to be the young dream builders of the "Dream Team"? "Guide students to count their dreams, look forward to the future, and grow healthily; help students realize their dreams, be brave in innovation, and become talents in an all-round way." Professor Huang Rong, dean of the School of Mathematics and Computational Sciences of Hunan University of Science and Technology, felt deeply. In recent years, the college has actively responded to social concerns, vividly responded to practical needs, rationally returned to the original purpose of education, strengthened the quality of education with the characteristics of disciplines and majors, carefully constructed the "digital dream space" education platform, and explored a unique talent training path. The team of "Digital Dream Space", which guides dreams with its own characteristics, builds a "big ideological and political" classroom with its own characteristics and disciplines, integrates belief education in multiple ways, and focuses on improving the ideological pattern, knowledge pattern and thinking pattern of talent cultivation through the "three teachers" education model of ideological and political instructors, professional instructors and practical instructors. Taking root in the "dream space" and guiding dreams has become the core value pursuit of the team's education. Liu Xueyong, the finalist of the "National College Counselor of the Year" and the deputy secretary of the Party Committee of the college, is a typical representative. She has always adhered to the "dream space" and guided the students' dreams with the discipline thought. As a front-line full-time instructor, I have been doing this for 23 years. Now, she has deeply fallen in love with "Digital Dream Space", insists on passing on the torch, attracts more excellent teachers to "Digital Dream Space", and devotes herself to talent training. "The 'Digital Dream Space' has witnessed my sweat and laughter, and left me with unique memories. Here is the starting point of my dream and the foundation of my belief." Recalling the impact of the 'Digital Dream Space' on myself, Yan Lianglin, the star of self-improvement of Chinese college students and the 2016 undergraduate majoring in information and computing science, was moved to tears several times. Thanks to the company of "Digital Dream Space", Yan Lianglin was selected into the list of national scholarship winners of 100 undergraduate and junior college students in the country, and won 9 national awards such as the first prize of the National Mathematical Modeling Contest, and was successfully exempted from studying for master's degree at the University of Chinese Academy of Sciences. Now, he is studying for doctor's degree at the University of Chinese Academy of Sciences. With the spirit of professional education, empowering dreams, stimulating students' innovative potential and cultivating students' professional spirit, "Digital Dream Space" is guided by the "three high" teaching mode of high-level courses, high-level platforms and high-level teachers, integrating scientific research results and teaching research results with professional content, gathering and creating national curriculum resources, promoting the teaching reform of professional courses, and making full use of multimedia, virtual simulation and other information technologies, Research human-computer interaction, scene representation, simulation operation and other information-based teaching methods to plug the wings of dreams. In order to further promote the transformation of specialty construction to application-oriented, and continuously improve the quality of specialty application, the college takes the national-level first-class specialty construction site "Information and Computing Science" as the platform, and the national-level first-class undergraduate course
