“…Using these specific fluency measures and a pretest and posttest design, researchers have reported statistically significant gains in L2 fluency after a semester abroad among American learners of French (Freed, ; Freed et al., ), Spanish (O'Brien et al., ; Segalowitz & Freed, ) and Mandarin (Du, ). Fluency measures that have been shown to significantly increase for learners after a sojourn abroad include speech rate (D'Amico, ; Du, ; Llanes & Muñoz, ; Segalowitz & Freed, ; Towell et al., ), longest run without unfilled or filled pauses (Llanes & Muñoz, ; Segalowitz & Freed, ), mean length of run without filled pauses (Segalowitz & Freed, ), mean length of run without unfilled pauses (D'Amico, ; Towell et al., ), repair rate (D'Amico, ), and number of words in the longest turn (Du, ; Segalowitz & Freed, ).…”
