日本語を母国語とする日本人の条件表現に関する調査 －表現教育の一環としての選択肢型と単答型の設問調査結果の対照－

Abstract

As an investigation of expressions such as ば(ba), と(to), たら(tara), and なら(nara) showing coordinate condition in Japanese language, the purpose of this study is to clearly establish the status of conditional expressions by comparison and analysis of results of a short‐answer survey with those of a selective survey conducted in 2008. Based on the comparison and analysis of the results of the two surveys on ば(ba), と(to), たら(tara), and なら(nara), indicating various semantic usages of conditional expressions, the subjects selected たら(tara) more in semantic usages of ば(ba) and と(to), and some of them selected ば(ba) in semantic usages of と(to) and たら(tara) indicating factual usages, as for the selective survey. In both selective and short‐answer surveys, selecting たら(tara) was high in semantic usages of ば(ba) and たら(tara), while some of the subjects selected と(to), which was not supposed to be selected. In the selective survey only, ば(ba) was selected in semantic usages of と(to) and たら(tara), indicating the subjects used them mixed. In other words, only for the selective survey, young Japanese in colleges used ば(ba), と(to), たら(tara), and なら(nara) mixed without a clear classification of their semantic domains, many of them selecting them in a broader sense based on context. However, given that たら(tara) and ば(ba) were selected almost evenly in the selective survey but ば(ba) was overwhelmingly selected in the short‐answer survey, the use of たら(tara) in a broader sense or mixed with other expressions was not established in the results of the short‐answer survey.
