APP英语口语考试信度的实证分析——以FiF口语训练APP为例

Reliability of APP Oral Proficiency Interview: a Case Study of “FiF” APP

为检验APP英语口语考试的信度,以FiF口语训练APP为例,安排420名考生分别参加APP口语考试与传统面试型口语考试。通过与传统口语考试的成绩比较分析APP口语考试的信度。研究发现:两种测试方法具有较好的内部一致性,评分没有明显差异,信度良好;APP口语考试与传统面试型口语考试成绩显著相关,具有较好的效度及可替代性;APP口语考试的优势是可缩短考生考试等待时长、节省教师人力、即时且客观地打出分数;但APP的施测维度具有局限性,主要适用于常规能力测试,而交际口试题型应选择传统面试型口语方式考试。

This paper made a comparable study of the reliability , validity and correlation of A O P I based on theperformance of 420 candidates in A P P Oral Proficiency Interview （ A O P I ） and Oral Proficiency Interview（OPI） respectively. Research shows that both A O P I and OPI have high validity and reliability. There is nosignificant difference between their ratings, but rather, there is significant correlation between A O P I and OPIscores. A O P I can replace OPI to an extent. Its advantage lies in a much shorter wait for the candidates , reducedmarking manpower and immediate and objective scoring. However, A O P I is limited in the testing dimensionsand OPI is preferable for communicative types of questions.
