Validity, Reliability, Practicality and Backwash Explanations Activity 3

Validity: The test needs to have validity since the purpose of it is to measure what we are teaching thinking about what do we want to test, for example, if we are going to focus in a specific skill (reading, grammar, etc.).

Reliability: A test has to be reliable, if the instructions are not clear it will result difficult to the students to do an incoherent test and for the teacher it will be harder to get good results. Let’s take into consideration that we as teachers are the ones responsible for doing a reliable test (of course if we design it because some schools provide their own tests).

 

Practicality: This means the way that the teacher grades a test, it’s necessary that students know how many points or what score does each activity in the test has; it must be well done and accurately.

Backwash: It’s a paper which shows how testing can influence in the teaching and learning aspects, it can be done after or during a test; it displays feedback. Backwash means to go backwards; it can present negative and positive effects in the students’ learning or teaching process.

Do you know if the tests you have been using or done are valid, reliable, and practical or if they have a negative or positive backwash effect in teaching and learning?

The test that we used was valid, reliable and practical because it was testing the skills that wanted the teacher. It was reliable because it was well done and it was focused on what they saw in class.
