近年來女性教師在各級學校所佔的比例逐漸增加，這是否意味著女性教師逐漸成為主流？還是僅為一種偶然現象？經由時間數列轉換模式分析，發現：第一，在小學，教師人數的增長是以女性教師為主；第二，在中學，男女教師數皆可預測教師總數的增減；第三，在大專，「女性教師數與教師總數之間」與「男性教師數與教師總數之間」皆未呈現穩定的關係，所以難以區分哪一種性別的教師才是主流；第四，在大專，女性教師數可預測7年後的女性學生數。最後，作者對本研究的限制以及後續研究方向，提出若干討論。

In recent years, the percentage of female teachers at all levels has been gradually increasing. Does it imply that female teachers are becoming the majority？Or is it a random phenomenon？By means of time series analysis, the author discovered：first, in elementary schools, the growth of the number of teachers accorded with that of female teachers；second, in high schools, we could predict the total number of teachers according to the number of either sex；third, in higher education, it was difficult to established which sex is the majority ；finally, we could predict the number of female students in seven years on the basis of the number of female teachers in the current year. The author also discussed that limitation of the research and possible approaches for future research.
