In collecting data, qualitative data were collected by using observation, interview, questionnaires, and quantitative data by using test. The qualitative data were analyzed using Interactive Model of Data Analysis as propounded by Matthew M. Miles and A.M. Huberman. The results of the research showed that Learning Cell Technique was able to improve the students’ reading skill. It was proven by the increase of the students’ mean score from 6.44 in pre-test to 7.15 in cycle 1, and 7.87 in cycle 2.
