Applying an Argument-Based Approach
Chapter 5: Validation Study
1 For validation study 1 I claim that the Russian Elicited Imitation Test can be used for controlling initial L2 oracy skills and can be used in studies conducted in two educational settings. Since specifying test use is the first step in the process of test development and validation the chapter starts with a section that specifies test use and the context. I then report on the developmental stage, which consists of two parts: creation of the test and development of the interpretive argument. I then report on the appraisal stage of the evaluation of the EIT which seeks to challenge the interpretive argument. Finally, I discuss the results of the validation study in connection with the interpretive argument developed for the specified test use. 5.1 Test use and context Two researchers in the USA and Germany5 want to investigate the effect of task manipulation (e.g., levels of complexity, type of input) on students’ task performance in an oral task. Participants of the study are enrolled in Russian courses of different levels defined by the local curricula or frameworks (ACTFL proficiency guidelines, CEFR). They have accomplished at least one semester of Russian study. There is vari- ation in students’ language proficiency between groups and probably within groups in both educational settings as well as across them. Since task performance can at least to some extent depend on students’ L2 oral proficiency, initial L2 proficiency should be controlled for in order to isolate the casual factors under investigation. Depending on the...
