The researcher in this study utilized the Montessori concepts and materials that emphasize the use of hands-on manipulatives in the classroom with 10 adult English language learners ranging from ages 18-60. The purpose was to investigate whether or not hands-on manipulatives were effective in aiding adult English language learners to acquire English. The term English Language Learner (ELL) is used for any student learning English in the United States. For confidentiality purposes, this study uses abbreviated versions of the students' names. Reference to an ELL's home country may be alluded to merely for the sake of providing background information to the reader. The researcher facilitated all the English language lessons as well as observed the participants' reactions to the material. Some of the observation notes will be provided when needed in order to provide reports on the effectiveness of the materials used with ELLs.
