The main aim of this research is to discuss the learning effect of students learning situation English vocabulary under the influence of FSVL learning strategy, which is assisted with handheld device APP. Hence, we develop a handheld APP device with dedication to situation English vocabulary learning. With this program, we help students use FSVL learning strategy so as to keep learning activities, for example, situation learning, under control. The subjects are 80 college students and 1 certificated teacher. With the aspect of knowing the influence of FSVL learning activities, the experiment categorized students into two division: one with handheld device APP and one with traditional equipment in normal classroom. We obtain the research result by way of interviews, tests, and ARCS motivation questionnaire. The result displays the fact that, by comparison with those learning in traditional classroom, subjects learning English vocabulary with handheld device APP gain higher performance in both learning motivation and learning outcome.
