There are many studies on motivation in speaking skills, but generally do not discuss directly about the factors that play a role in increasing motivation, especially in the development of speaking skills. This research formulates the problem of what factors play a role in the high motivation of students in the development of speaking skills. Descriptive qualitative research method was used in the study, to facilitate the researcher in gaining in-depth understanding. Five students who have high motivation became the population in this study, with a sample determined using purposive sampling technique. Data were collected using field text in the form of indicators of high motivation and interviews formed based on aspects of interaction, continuously, and situation. Data analysis in this study used interactive techniques involving data reduction, data display and conclusion making. The results of this study show that students' high motivation can be improved with three factors: personal factors, dynamic factors in learning, and the environment where students live. Personal factors provide support and increase students' self-confidence. Dynamic factors in learning involve students' talents and interests in learning as well as the positive feedback students get in student learning. The student's learning environment helps to establish a routine that supports the development of speaking skills. With these findings, this study suggests establishing a positive learning environment, as well as the use of learning strategies that match students' interests, so that it can facilitate students in increasing motivation.
