Evaluación en la enseñanza del inglés como lengua extranjera Maria Alejandra Colmenarez C.I: V-25.771.824 How can a teacher tackle the problems that validity, reliability and practicality may pose when assessing students? The process of teaching languages comprehends a wide variety of paths that need to be followed in order to achieve the goal of teaching and be able to witness that students use what they learned in real life contexts. Validity, reliability and practicality are concepts used to guarantee that the process of assessing students gives a meaningful result. An extensive amount of questions come up when assessing students. Therefore, the notions of these concepts need to be as clear as possible, so the results of the assessments be the most accurate as possible. Dealing with assessment is not only to know if the student´s performance has had an improvement or not, but also to check the teacher´s knowledge on evaluating and assessing. Knowing the concepts that were previously mentioned is ideal to detect problems and find solutions that might appear when assessing and testing students. Planning lessons is a crucial step for the upcoming phases of classes. Every single teacher or instructor should have a record of their students’ progress. This is vital because assessment and testing need to be lively present when valuing scholars; measuring what it is supposed to be measured is decisive when running an idyllic process of estimating abilities. In addition, some problems might affect the validity of an assessment, such as, cultural or educational background of pupils. One effective way of being assured of what was taught is being evaluated and that some students don´t have a step forward is to emphasize, review, and highlight only what was taught by checking and creating the evaluation based on the lesson plans and records that each teacher or professor has from the classes. As it has been formerly stated validity allows teachers to create and evaluate in the most accurate way what has been imparted, there is one more notion that is required in the procedure of estimating in the teaching process. Reliability, it can be explained as the results that were obtained from the previous evaluation, one process is connected and follows the other. In one hand, using them has usually an ideal result. However, problems will possibly appear when receiving the assessments back. They can be physical and psychological conditions the students and teachers, the administration of the test and some more can affect a test and therefore the result of it. On the other hand, these external factors that can make the score variate cannot be fully controlled by the teacher, as long as teachers evaluate what they are supposed to measure and to be as precise as much with the instructions and steps that you explain, objectives can be achieved. Several elements need to be taken into account when formerly assessing students nevertheless three of the elements can be mentioned as the obligatory ones, two of them have already been described. Likewise, practicality is as important as the ones that were previously labelled. Practicality, as the name suggests refers to how easy, in general terms, a test can be. As it has steps that need to be emphasized when administering it, such as, the price of the photocopy, how easy is to fill it and the time that will take to correct it. It also has difficulties that can appear, such as, the limits that generate when creating a practical test. Paying attention to all the factors as money, teachers aids in the classrooms and more can be exhausting and time demanding for teachers. Therefore, a deep evaluation and analysis obligatory need to be run in order to evaluate according to the characteristics of each group and student. Decisions are made daily on language teaching assessment and testing. The way to create the most precise assessment is by knowing and having an undisturbed image of what are we teaching and who are we teaching. In addition, problems may come daily, too. Solutions for these problemS need to be taken into consideration when making decisions regarding to assessment and students. External factors usually interrupt teachers and students in all aspects, as teachers are the ones making the most important decisions in the classroom, they need to have justifications and answers of why an assessment has that specific form. Background, results and even the place where the school or university is located has an effect on the assessment of the students. Teachers will be able to create the ideal object to measure as long as they know their students according to the information a teacher should have.
