英国圣安德鲁斯大学论文代写:雅思考试的可靠性

雅思考试的可靠性也必须被考虑。一个单一的审查员负责对候选人进行评级,因此,由于口译员的解释,所以必须对其内部的可靠性提出质疑,但只有一个测试者。得分分为4个类别(附录4),在这4个类别中没有深入的细分,所以得分是由审查员决定的。雅思口语考试的效果有一定的局限性。总的来说,这是一项有意义的测试,它显示了一些领域的有效性和可靠性,但在一些领域,有效性和可靠性都没有达到所显示的程度。以下的建议可以使雅思口语考试更有效、更可靠——为考生在第一部分中自由交谈提供更多的时间。通过这种方式,我们可以从候选人中获得更多真实的数据,并对候选人的实际能力进行更深入的分析。更多的任务会从候选人那里获得更好的表现——讨论一个代表不同的交流过程的图片或任务。评分等级应该开放给更多的变量以提供更广阔的视野,最后,不止一个考官会确保一个更可靠的评估。

The reliability of the IELTS test must also be looked at. A single examiner is responsible for rating the candidate, therefore, the inter-rater reliability has to be questioned due to interpretation but a single person of the test taker. The scoring is split between four categories (appendix 4) – within these four categories there is no in-depth breakdown so scoring is at the discretion of the examiner.The effectiveness of the IELTS speaking test has some limitations. Overall it is a meaningful test which shows validity and reliability in some areas but there are areas in which both validity and reliability fall short as has been shown. The following suggestions could make the IELTS speaking test somewhat more valid and reliable – provide more time for the candidate to talk freely in the first section. In this way we could elicit more authentic data from the candidate and be provided with a more in-depth analysis of the actual ability the candidate has. More tasks would elicit a better performance from the candidate – discussion about a picture or tasks which represent different communicative processes. The grading scale should be open to more variables to provide a broader perspective and finally, more than one examiner would ensure a more reliable assessment.
