This study examines and refines a grammar placement test using the classical test analysis. The participants were 44 international students who were studying Japanese at Okayama University in Japan. After revisions were carried out on grammar test items that are high in item discrimination and low in item facility. The new version was found to be more efficient than the old one, since it make the overall test more difficult while keeping the same reliability level as before. When the result of dividing classes was predicted, it was found that new grammar test items were significant predictors.

This purpose of present study was to develop an evaluation scale in order to study how native speakers evaluate the speech and behavior of Japanese learners. To confirm the reliability and the validity of this scale, I carried out a questionnaire survey by viewing how 83 native speakers responded these items after they saw a videotape recording of a learner's free conversation with a native speaker. The questionnaires contain of 55 items (34 items for learners' competence evaluated by native speakers and 21 items for overall evaluation) were selected from the former related studies and the result of follow-up interview to 50 native speakers. In this analysis, 5 factors for learners' competence evaluated by native speakers and 3 factors for overall evaluation were extracted from the factor analysis first. The reliability of the scale was confirmed by the Good-Poor analysis and Cronbach's coefficient alpha. Furthermore, I propose the hypothesis of causal relation model of native speakers' evaluation based on Peason's product-moment correlation coefficient and the multiple regression analysis. As a result, the reliability and the validity of the scale are proved. Arid from my hypothesis of the causal relation model of native speakers' evaluation, it was found that 1) 'Expressiveness', 'interlocution competence', 'Listener-friendliness and comprehensibility' and 'vocabulary and expression' influence the evaluation of 'Japanese oral proficiency'. 2) 'Communication strategies' influences the evaluation of 'approachability'. 3) 'Communication strategies' and 'expressiveness' influence the evaluation of 'positive attitude'.

The purpose is to examine what points of Japanese learners' performance tend to be evaluated positively or negatively and judged as good or bad points in conversations with 25 Japanese native speakers and 25 Japanese language teachers. In this research, participants evaluated the non-Japanese university students' (NNS) Japanese. If they felt the NNS's Japanese was good, they gave ○. If they felt the NNS's Jpapanese was bad, they gave × as they watched video recordings of the learners' free conversations with Japanese native speakers. Participants also gave comments of their reasons for awarding ○ or ×. All comments were classified onto cards according to their content. These were treated as evaluation factors.The results show that both Japanese native speakers and Japanese language teachers tend to evaluate:(1) vocabulary and expression, discourse competence and communication strategies positively.(2) grammar and pronunciation negatively.(3) Japanese native speakers tend to evaluate sociolinguistic competence positively, whereas Japanese language teachers tend to evaluate it negatively.
