Thinking activity : Testing and Evaluation

 Hello readers, welcome to my blog.... Here is my task upon to  write given question... 

1) Validity and reliability  test .

2) Practicality of the test .

3) What do you understand by backwash?

 

4) Difference between assessment and evaluation ?

5) How do you define good assessment? 

  

1)Validity and reliability test .

    Let's see the  definition of these two words first....

Reliability

Reliability refers to how consistently a method measures something. If the same result can be consistently achieved by using the same methods under the same circumstances, the measurement is considered reliable.

Validity

 

 Validity refers to how accurately a method measures what it is intended to measure. If research has high validity, that means it produces results that correspond to real properties, characteristics, and variations in the physical or social world.

2)Practicality of the test .

Practicality

It refers to the economy of time, effort and money in testing. In other words, a test should be easy to design, easy to administer, easy to mark, and easy to interpret the results (Bachman and Palmer, 1996). Moreover, according to Brown (2004) said that the test that is practical it needs to be within the means of financial limitations, appropriate time constraints, easy to administrator, score, and interpret.

3) What do you understand by backwash?

Backwash is the effect that knowledge of the contents of a test may have on the course which precedes it. It may be positive or negative.

Example : If students are working towards an exam where all of the test items focus on grammatical accuracy, the teacher (possibly at the students instigation) may spend much of the preceding course focusing on this area - and possibly neglecting other areas that they will need outside the course such as spoken fluency or listening. Thus the test would have negative backwash - it pushed the teacher into "teaching for the test" rather than providing a balanced course which dealt with all the students needs and developed other areas of competence than just grammatical knowledge.

4) Difference between assessment and evaluation ?

5) How do you define good assessment?

Assessment literacy involves understanding how assessments are made, what type of assessments answer what questions, and how the data from assessments can be used to help teachers, students, parents, and other stakeholders make decisions about teaching and learning. Assessment designers strive to create assessments that show a high degree of fidelity to the following five traits:

1.  Content validity

2.  Reliability

3.  Fairness

4.  Student engagement and motivation

5.  Consequential relevance
