This paper presents the application of a framework for integrating web resources in LMS. The case study was carried out in a rural school of Cauca-Colombia. During the experience the LMS DotLRN was used to support different areas of middle school education as well as B-Learning activities. For performing the evaluation classes were given to two groups of students: one group was supported by a LMS, and in other group, the same subjects were taught conventionally. Finally academic performance and effectiveness of both approaches was analyzed.
