1 Assessment Use Argument Nancy Powers Chief of English Testing Section SHAPE, Mons, Belgium Sept 2013
2 Introduction Validity is an integrated evaluative judgment of the degree to which empirical evidence and theoretical rationales support the adequacy and appropriateness of inferences and actions based on test scores” (Messick 1989: 13)
3 Assessment Use Argument Based on Toulmin’s (2003) approach to practical reasoning Justification Accountability
4 According to Bachman & Palmer Assessment development consists of two parallel processes that serve two purposes. 1.The assessment production process 2.The assessment justification process (p. 430, 2010)
5 Therefore… An AUA is a theoretical framework that provides a rationale and set of procedures for justifying the intended uses of the assessment.
6 The nitty-gritty of an AUA It is comprised of 4 parts 1. Claims 1.The beneficial consequences of an assessment 2.The decisions that are made 3.The interpretations that are made 4.The assessment records 2. Warrant – statements that elaborate the claims
7 The nitty-gritty of an AUA (cont’d) Not everyone will agree with us 3. Rebuttal – counterclaim 4. Backing – evidence supporting the warrants includes feedback from stakeholders through questionnaires, verbal protocols, observations, interviews, previous research, statistical analyses
8 An AUA at work Lots of theory… Concrete example: Justifying the inclusion of videos in a listening test
9 Claim 1: The consequences are beneficial I make the claim that The consequences of using a video listening test are beneficial to the test developers and to the students. So, what does this mean? I need to elaborate.
10 Warrant The consequences of using the VLT that are specific to the test developers and to the students will be beneficial. The test developers will develop tests that are more authentic and better reflect the TLU domain Students can use the visual cues to help with comprehension The context will be clear thereby reducing student anxiety
11 Rebuttals I disagree with you! The consequences of using the VLT that are specific to the test developers and to the students will NOT be beneficial. Videos will be distracting Attending to multiple sources of stimulation is more tiring & demanding
12 Backing: Collection of evidence that justify your claims 1.The students who trialled the test reported that… “The video aspect helped to ground the task, making it more authentic than just an audio test” “It gave focus to me, therefore allowing me to listen. Often, when listening to audio-only, my mind wanders, i.e. I think of something else, therefore missing the listening text.” “They [the videos] were relaxing; therefore there was no mental block to listening because of nervousness.” 2.The use of videos can be theoretically justified in that it introduces construct-relevant variance (Wagner, 2002, 2007)
13 Backing cont’d 3.Wagner (2010) found that student performance on a listening test that included videos increased 6.5% 4.If test task characteristics are similar to the TLU characteristics, then the test can be seen as having construct validity (Bachman & Palmer, 1996)
14 Claim 2: Decisions made The decisions to award a proficiency level reflect existing educational and societal values and the content/task/accuracy statements as stated in the NATO STANAG 6001 Language Proficiency Levels; and are equitable for those students who are placed at different proficiency levels. These decisions are made by the test developers and refer to which proficiency level the students belong. The individuals affected by these decisions are the students and the teachers of the MTCP program.
15 Warrant: Values sensitivity Relevant educational values of CDA are carefully considered in the proficiency level decisions that are made. Rebuttal: Relevant educational values of CDA are NOT carefully considered in the proficiency level decisions that are made.
16 Backing: CDA governed by two documents: Qualification Standard and the Foreign National Training Plan VLT respects the C/T/A statements for each proficiency level in STANAG 6001
17 Warrant : Equitability Test takers and teachers are fully informed about how the decision will be made. Rebuttal: Test takers and teachers are NOT fully informed about how the decision will be made.
18 Backing: The testing section conducts information sessions with teachers and testers when introducing new testing methods. Candidate’s Guide
19 Claim 3: Interpretations The interpretations about the students’ ability to utilize verbal and non- verbal behaviour to comprehend the main idea, explicitly stated information and implicit information are meaningful in terms of the construct definition of listening comprehension, impartial to all groups of test takers, generalizable to tasks that resemble the TLU, and relevant to and sufficient for the proficiency level decisions that are to be made.
20 Warrant : Meaningful The claim is meaningful in terms of listening to and comprehending general English with respect to the construct definition. Rebuttal: The claim is NOT meaningful in terms of listening to and comprehending general English with respect to the construct definition.
21 Backing: Meaningful The construct definition is based on research on listening comprehension. The items were developed according to the NATO STANAG 6001 Proficiency levels. Item specs
22 Warrant: Impartiality Test takers are treated impartially during all aspects of the administration of the assessment Rebuttal: Test takers are NOT treated impartially during all aspects of the administration of the assessment
23 Backing: Impartiality Candidate’s guide, all sessions administered in the same way every time. All students are given the same test with the same instructions, despite their country of origin, their rank, their gender, etc. Generalizable Relevant Sufficient
24 Claim 4 Assessment Records The scores from the video listening test are consistent across different forms and administrations of the test, across students from different military trades, and across groups with different nationalities and first languages.
25 Warrants: Inter/Intra rater reliability Scored the same way across administrations Rebuttal: no rebuttal Backing: this is multiple-choice, computer-delivered test: no inter/intra rater reliability needed internal algorithm in computer program for scoring
26 Conclusion: in a nutshell Basically you are saying something about the test that you have designed You make these claims clear by elaborating on what you mean. Then, you address any perspective that goes against what you have claimed and gather evidence that supports your point of view.
