What does "work-study practice" mean?

That is to say, the Party branch of the work-study program "practices the eight-character value orientation and strives to improve the cultivation of party spirit"

In the party class, the eight-character value orientation of "justice, tolerance, responsibility and honesty" is explained in detail, and I hope that every comrade will take the lead in "practicing the eight-character value orientation" and constantly improve the cultivation of party spirit and teachers' morality. Many teachers spoke enthusiastically and talked about their feelings and suggestions. The atmosphere was warm and applause continued. Everyone agrees that teachers in party member, as a special education system, should take the healthy development of every special student as the foundation, care for students, suffer hardships first, enjoy them later, be self-denying and selfless, truly integrate the responsibilities of party member and teachers into the blood of the soul, penetrate into spiritual beliefs, and interpret the "eight-character value orientation" with their own actions.
