1.- No, because I have a lot of students but I analyse my students and observe the evolution they are having during the class, and through the classes.I can notice their weakneses and strengths too.
2.-I do not think so, I consider that continuous assessment gives enough information or clear arguments to the teacher and with this he or she can grade students.
3.-The information that we can obtain from the continuous assessment is, if the are understanding the vocabulary, concepts, structures and using the language, especifically if they are using the English trying to communicate their ideas, feelings and thoughts.
4.-No, but this is a difficult work since the teacher must be motivated, observant and carry out an investigation about the group and each of is her students, to adapt or look for another activities.
