四英語四甲 497c0033 周泳嫺 Summary Assessment refers to the act of collecting information and making judgments about a language learner’s knowledge of a language and ability to use it. Some people consider testing and assessment are synonym, but assessment has border range than test such as observation, journals and portfolios. In language programmes, Broadfoot identifies a number of assessment purposes: assessment for curriculum, assessment for communication and assessment for acountavility. Assessment purpose is closely tied to the stakes and in high stakes situations the results of assessment may have a significant effect on test-takers lives. The ideal of involvement need to be balanced against the realities of implementation and the need for tests and assessments to demonstrate acceptable levels of validity and reliability. Comment By reading this article I finally understand the difference between testing an assessment. The range of testing is smaller than assessment such as a test on the class and assessment is like a interview or a portfolio. I also learn that it’s very hard to find a balance between the realities and the needs of the test and other factors.
