Therefore learning methods and strategies are very influential in the learning process and student's motivation to study. Learning strategies included in the design of domain learning technology.

While the process, the researcher has a source of data from the mufradat/vocabulary learning process as well as the students involved in it. This paper discusses the implementation of learning technology (mind mapping strategy) to solve the problem of learning mufradat. And The results of this study prove that the mind mapping strategy help to improve mufradat mastery of the students and them following the learning process with pleasure.
