Strategy of improving student achievement in English learning through concentration approach

This research is a research about the effect of student mobility in the class on the concentration of learning and its influence on learning achievement. Mobility in the classroom is done through simple interactive learning, which is an effort to invite students to always move and always active in the learning process. Departing from the problem that the concentration of students decreased in line with the length of the lecture and the lack of interaction of students in the class, then made a strategy that allows the concentration of students to stay awake during the lecture process is by improving the mobility of students in the classroom. In order to know the effect of treatment/intervention on the subject condition, there will be a real experimental study using two crossover design. Assessment of quality of learning process done by research 2 cycle, wherein each cycle ended with giving test/questionnaire. The results showed that the concentration indicator consisting of speed, accuracy, and constancy increased significantly after the students improved their mobility in the classroom. Increased concentrations also have a significant impact on student achievement.
