What of the Principles of Language Assessment were violated? Justify one of them with a fragment of the video where you noticed it.

Did the teacher have a construct when doing or delivering the test? If so, what was it?

What kind of test was used in this video? (e.g., placement test, diagnostic...). Explain why.

What things would you do differently from the teacher of the video to ensure that your test works well in terms of assessment?

I think they violated the validity, construct validity, face validity, security, reliability. You can see that the students are talking between each other, also using the phone as well in this case that is a violation of security of the assessment.

I think that he did not because he gave a test that could not assess the knowledge of the students, at the same time he did not give clear instructions and the purpose/goals of the test.

I think it is an objective test because the “purpose” was to check students' knowledge but only through multiple choice questions, True or false and this kind of questions.

To assess a topic such as math I would give precise instructions and at the same time evaluate what I have taught in math, not what was first, the egg or the chicken that has nothing to do with the topic, at the same time don't implicate the validity, security and the others.
