This study explores the teaching practices of recently returned Latter-day Saint (LDS) missionaries who voluntarily taught the English language on their full-time missions' serving for The Church of Jesus Christ of Latter-day Saints throughout various parts of the world. The analyses performed in this research offer an insider's perspective by looking at a large selection of qualitative data gathered directly from these missionaries to provide evidential insight into what those practices are, including the most effective and the most ineffective teaching practices as principally perceived by the missionaries themselves. Thus far, there has been no research reported or data gathered on this topic on the same global scale, and to the same academic level. However, such a study is extremely necessary and beneficial towards refining the focus of the missionary taught English language classes, as well as the quality of teaching that the missionaries provide as they strive to serve and benefit the communities around them.
