Assignment 1
Select an assessment task used in your language teaching context you are familiar with. Outline the basic principles underlying the assessment. Discuss whether the task meets the qualities of effective assessment in terms of reliability and validity and whether it successfully measures your learners’ language ability. If not, what are some of the practical considerations to enhance its effectiveness?

I. INTRODUCTION
At my school, the Asian International School (secondary school), students usually take English tests. The format of the tests for grade 6 is based on Cambridge English: Key, also known as the Key English Test (KET). Therefore, this paper will consider the KET (listening paper), which, at A2 level, is formally recognized …show more content…

In contrast, according to Brown (2004), there are five principles of language assessment: Practicality, Reliability, Validity, Authenticity, and Washback. Due to the time constraints, I just focus on validity and reliability.
2.1.1. Validity
According to Gronlund’s viewpoint (as cited in Brown ,2004), validity is ‘the extent to which inferences made from assessment results are appropriate, meaningful, and useful in terms of the purpose of the assessment’. Viewing from the similar perspective, Hughes (as cited in Brown, 2004) mentioned that Validity means discovering whether a test ‘measures accurately what it is intended to measure’. And there are five types of evidence of validity (Brown, 2004, p.22):
1. Content validity: any attempt to show that the content of the test is a representative sample from the domain that is to be tested (to achieve content validity in classroom assessment: test performance directly).
2. Criterion-related evidence: is the extent to which the ‘criterion’ of the test has actually been reached. It includes two …show more content…

How to increase validity and reliability
According to The Council of Europe (2001, p.188), subjectivity in assessment can be reduced, and validity and reliability thus increased by taking steps like the following:
- Developing a specification for the content of the assessment, for example based upon a framework of reference common to the context involved
- Using pooled judgements to select content and/or to rate performances
- Adopting standard procedures governing how the assessments should be carried out
- Providing definitive marking keys for indirect tests and basing judgements in direct tests on specific defined criteria
- Requiring multiple judgements and/or weighting of different factors
- Undertaking appropriate training in relation to assessment guidelines
- Checking the quality of the assessment (validity, reliability) by analysing assessment data.
3. Language ability
According to Bachman (1990), language ability includes the knowledge/competence of language and the capacity for implementing this competence. It is the ability not only to apply the grammatical rules of a language in order to form grammatically correct sentences but also to know when and where to use these sentences and to whom.A framework of communicative language ability (CLA) includes three components: language competence, strategic competence, and psychophysiological mechanisms (Figure 3.1) (Bachman, 1990,
