The purpose of this study is to clarify whether there is an effectiveness of teaching on order of difficulty of onset consonant clusters in English, and whether explicit instruction is effective in improving student production of onset consonant clusters. Previous studies have revealed that Japanese native speakers tend to insert vowels between consonant clusters. Consonant clusters were chosen from the Lingua Franca Core, Jenkins (2000), to be investigated. Three different categories of words were chosen: C[－voice]-C[－voice], C[－voice]-C[+voice], and C[+voice]-C[+voice]. Thirty low-level university students participated in the experiment. They were divided into three groups of 10:one control and two experimental groups. The students in Experimental Group 2 were explicitly instructed. All groups were recorded reading a passage with target words chosen from the above three categories. After the analysis of the data, effective and ineffective teaching strategies were revealed.
