Hello professor,
I am a postgraduate student at the School of Physical Education of Dalian University. Currently, I am working on my master's thesis titled "Research on the Construction of the Technical and Tactical Evaluation System for Male U12 School Football Players - Taking the Football Featured Schools in Jinpu New District, Dalian City as an Example". In order to build a technical and tactical evaluation system for male U12 school football players, we have already converted various indicators into questions and formed the final expert survey scale. This questionnaire is the first round of the Delphi expert questionnaire and is an important part of my master's thesis. Your valuable opinions will provide significant value to this research. Based on the needs of this research, this Delphi method questionnaire needs to be conducted two to three times. Please evaluate the importance of the indicators represented by different items in the scale based on your professional knowledge and understanding of the research content. Your answers are crucial for the successful completion of this research, and your valuable suggestions will also add value to this study. Sincerely thank you for your support and cooperation in this project. I wish you good health and smooth work!
