In second language learning, unawareness of the differences between correct and incorrect pronunciations is one of the largest obstacles for mispronunciation correction. In order to make the feedback more discriminatively perceptible, this paper presents a novel method for corrective feedback generation , namely, exaggerated feedback, for language learning.(More)
This paper investigated two different modification methods of graphene (GN) on ultramicroelectrode array (UMEA) and applied the GN modified UMEA for the determination of dissolved oxygen (DO). The UMEAs were fabricated by Micro Electro-Mechanical System (MEMS) technique and the radius of each ultramicroelectrode is 10 μm. GN-NH2 and GN-COOH were modified on(More)
