Japanese term or phrase: 1 次項 / 2 次項
This term appears twice in a paper that I'm translating. Could anyone explain what it means or give me a way of translating it. I'm assuming that it means the same in both of the following sentences but it could be slightly different.

Sentence 1 (from the literature review, explaining the effects of teacher characteristics on test outcomes):

篠崎(2008)は全国学力・学習状況調査の千葉県公立小中学校別データを用いた結果,教員平均年齢の1 次項と2 次項が小学校算数の平均正答率で負および正で,中学校国語,数学の平均正答率で正および負でそれぞれ統計的関係があることを確認している。

Sentence 2 (from the results of the study, explaining the effects of teacher experience on students' test scores in science):

また教歴は理科スコアに対して一次項が正,二次項が負であり,有意水準1%以下で統計的に有意である。

Thanks a lot,
