The Effect of Smart Phones' Application in Regular University English Class on Students' Learning Performance

We designed the web-based and client-responsive vocabulary drill resources targeted at the required new words and phrases from the English textbook of the university students, and let the students browse the web server and do the drill programs using their own smart phones via wireless network in the classroom for 10 to 20 minutes in every week's English class. The quasi experiment in one semester with this system resulted in the decrease of the grade mean distance from the treatment class to the control class in the regular exams, both with 98 students, from statistically significant level to not significant level. The grade means distance in vocabulary test from treatment class to control class was also decreased. Moreover, more students both from treatment class and from control class volunteered to use their smart phones to do the word drills.
