China’s teacher education reform has always advocated the establishment of a teacher-professional learning community to promote teacher professional development and school progress. In the Web 3.0 era, the increasingly open, secure, and fair network has created conditions for the teacher professional learning community to conduct data confirmation. However, in China, the phenomenon of a “silent spiral” has emerged in the professional learning community of teachers, that is, the inferior opinions of teachers in the professional learning community turn to “silent”, and the superior opinions shout, which to a certain extent hinders the creation, protection, and sharing of teacher metadata, affects the development of data right confirmation in the field of education, and slows down the pace of teacher education practice. This study mainly focuses on the value of building a Chinese teacher professional learning community in the Web 3.0 era, the specific difficulties and reasons, and how to develop a Chinese teacher professional learning community in the future. This study mainly adopts the method of documentary review and draws on the “spiral of silence” theory, which regards the expression of opinions and the spread of “silence” as a spiral process of social communication, and influences and restricts public opinion by creating an “opinion environment”. It is found that under the background of the Web 3.0 era, there is an information cocoon in the professional learning community of teachers, and teachers are affected by the diversity of information. Teachers fear independence and generally produce a herd mentality. It is easy to ignore the disadvantageous climate in the professional learning community of teachers, resulting in the continuous silence of teachers. In addition, teacher groups tend to be too stressed and unable to resist the opinion environment. Therefore, the research draws the following conclusions, the construction of teacher professional learning community should adhere to positive guidance, cultivate the correct learning concept, and build the core value concept; Strengthen teachers’ group consciousness, establish a common vision, and make teachers have a sense of belonging to the community; Coordinate the “online + offline”, build a learning mechanism, and salvage the silent voice of the group in the professional learning community of teachers; Provide supporting conditions around the key development issues of the community to promote the growth of opinion climate.
