When we talk about Validity, we state that testing and grading is part of the daily life for students and teachers. The validity of a test will be important, because it defines how much students are learning, and shows how well teachers are doing in class. Testing gives us a statistical score (scoring validity) which is used to produce information that is useful to check what it is measured. It is part of the background that belongs to students. Thus, validity will be important in the learning process because of the respect and commitment that has with showing if the methodological procedures teachers use, are having results when some knowledge must be evaluated, and if it works, there is going to come up reliability through the assessment process.
According to the text, we can find three main arguments to sustain the Validity of an assessment procedure. First, Validity is an instrument to measure, it does so through testing. It measures the performance of a student on specific tasks (quiz, oral exam, mid-terms, etc.). Second, Validity produces data; after measuring we have results that can be used to improve performance on tests in further activities. Finally, Validity is multifaceted; it needs complementary information to show evidences when a test is interpreted, there has to be more and different evidence to consider it, but every Validity will have the same value.

MMM, It seems to me that it was pretty difficult to understand your description of validity. It is true that it is very important that a test is valid but does validity really implies what you explained?
ResponderEliminarIn my opinion, validity is such a complex concept and by reading the explanation that you give in the first paragraph, it doesn't make that clear for me. However, although it is much more than what your wrote, I liked very much how simply you explained the elements that make validity fundamental for the assessment process.
ResponderEliminarThat explanation about validity was difficult to follow. However I could understantd the three arguments of validity that explain how important validity is for the learning process.
ResponderEliminarI think the explanations of the three arguments that support the concept of validity in every assessment work, are well expresed. However, I really think that the concept of validity does not need to much explanation than the one Paulina told us today.. Marco please remember the "doctor parable"
ResponderEliminarDear friend:
ResponderEliminarI think that you didn't understand the concept of validity very well. Try to remember what I said to you on monday and the comparison with the Doctor case. It was very simply and understandable.
I think you described validity well but you were not quite clear about its purposes. validity should measure what it is supposed to measure and nothing else. At the same time, its interpretations should be taken from the results you obtained in order to say if the assessment procedure was valid or not.
ResponderEliminar"Validity is a multifaceted instrument", you have mentioned the importance of collecting information during the whole process, it is necessary to obtain as much information as you can to make clear judgements.
ResponderEliminarLa validez es definativamente multifacética, y es un elemento esencial que debemos considerar en el proceso de la evaluación. Tenemos que buscar esta validez en muchos aspectos para empezar a asegurar una buena evaluación. Aunque sería posible desarrollar una evaluación sin este componente, somos más responsables como profesores cuando consideramos si nuestra evaluación sí está mediendo lo que debería medir, por ejemplo.
