1. The paper had better be published in your unit. If it was published before, some schools are ok.
2. What has nothing to do with what you have learned can only be pedagogy, that is, teaching research papers can.
At least one article is the first author, the others are the second authors, and the third author is meaningless.
4. The periodical must be a CN periodical.
You must have enough working years to evaluate the lecturer, but more papers can increase the possibility of your evaluation.
Lecturers (research positions) offer courses in universities or grant students professional training in their own fields, and at the same time deeply participate in their own professional disciplines, gain professional recognition through publishing papers, and strike a balance between teaching, training and thesis writing.
Generally speaking, a university lecturer is the only way to become a university professor. Teaching, scientific research, counseling students, accumulating teaching experience and exploring academic opinions in their work, and finally growing into a university professor.
