;With the rapid development of technology, a variety of mobile devices have come out. Many researchers have started to study how to implement mobile devices into the field of education. The reason is that mobile devices have many advantages, such as portability, multimedia tools, and network. It is found that there are not many opportunities for learners to practice listening and speaking in Taiwan′s English learning environment, which leads to the decline of learners′ oral ability. Therefore, this study will provide learners with an environment to practice oral speaking by taking advantage of the characteristics of mobile devices and situational learning.
For English teaching of junior high school students, this study developed a system, SmartVpen. The main function is to identify learners′ oral speech and give accurate feedback and to identify learners′ exercise questions and give appropriate answers through the cloud database. For the purpose of this study mainly discusses three groups of learners′ differences in learning and learning behavior, three groups of learners to the experimental group and control group 1 and control group 2, respectively, in which the experimental group using SmartVpen this institute development activities, and the control group 1 only using Android built-in function of activity, the control group 2 is no involvement of the traditional teaching of science and technology. The subjects of the study were eighth-grade learners with 69 participants over six weeks.
Research results show that the use of the system of learners, whether in the understanding of the English or English speaking ability is much better than any other learners, to further explore their learning behavior, found that the accuracy for speak English the most correlation and predictive, in other words, this study system can effectively promote learners′ spoken ability, especially with the feedback of the speech recognition accuracy is the most effective, because learners in order to achieve the highest accuracy, and to carry on the practice, to achieve the effect of mastery learning. On the other hand, it is found that learners practice more dialogues in the real situation than in the non-real situation, because learners are novel and interesting to get rid of the single situation in the classroom, thus triggering learners′ motivation to practice. It can be seen that practicing intelligent dialogue in an authentic environment an important factor to improve learners′ speak ability.
