Conversation table using Google Hangout: from online chat to F 2 F chat -written fluency and oral fluency development 2014 WAFLT Fall Conference Nov. 8 th, 2014 Kazuhide Takeuchi - Indiana University Bloomington
Outline 1. 2. 3. 4. 5. Purpose/motivation of the study Previous studies Present study Result/analysis Conclusion/suggestion
Purpose and motivation of this study 1. Time management • Four skills and culture • Larger class size • Curriculum 2. Practice opportunity • Balance of input and output • Participants’ level difference 3. Assessment • Subjective and objective • Practicality
Previous studies • CMC increase participation, motivation, understanding Payne and Ross (2005), Blake (2009), Yang et al (2012) • Higher improvement on speaking than face-to-face Payne and Whitney (2002) • Written production are related to oral production Payne and Whitney (2002), Toyoda and Harrison (2002) • Higher production rate = higher fluency Kormos and Denes (2004), Ginther et al (2010) • Other characteristics influencing fluency • Complexity, location of disfluency, balance Lennon (1989), Brand Gotz (2011)
Hypothesis 1. Online text chat style conversation table helps learners’ oral fluency development. 2. Temporal measures and holistic rating have a positive correlation.
Study 1 Spring 2014 • Who? • 4 Volunteered students from second and third year Japanese • 2 male and 2 female • One 3 rd year student and three Japanese native speakers participated only conversation table • What? • Treatment: weekly online text-chat style conversation table on Google Hangout. (about 6 weeks during the spring 2014) • Assessment: pre/post-test free speaking task (few minutes about winter/spring break) • Holistic rating and temporal measures
What is Google Hangouts? • Free instant messaging and video chat • Free! For Google+ account holder • No limitation for text-chat participants • Can be a private or an open group • Accessible from computer and smartphone
Google Hangouts sample
Temporal measures • Speaking rate (SR) = total number of mora divided by total time (including pause) • Articulation rate (AR) = total number of mora divided by total speaking time (excluding pause) • Phonation time ratio (PR) = total speaking time divided by total time • Mean length of run (MR) = total number of mora (excluding filled pause) divided by total number of runs (speech segment occurring between pause of 0. 25 sec or grater) *in this study, pause (filled/unfilled) was defined a duration of silence or non-word sound (i. e. filler) longer than 0. 25 seconds. Lennon 1990, Towel et al. (1996), Cucchiarini (1999), Kormos and Denes (2004), Payne and Ross (2005), Blake (2009), Ginther (2010), and Brand Gotz (2011)
<Insert audio here> なつやすみに、あ~・・ともだちと~うみにいき~(pause)ました。 Summer break time (filler) friends with (filler) beach direction go (pause)-past na tsu ya su mi ni ah~ to mo da chi to~ u mi ni iki~(pause) ma shi ta I went to a beach with friends this summer. Speaking time = Total time = Mora = 19 Run = 4 SR: = AR: = PR: = MR: 19/4 = 4. 75
Results Did not participate conversation table.
Result 2
Results and analysis • Very small improvement on production and rating. • Improvement without participating conversation table. But, • Higher production rate = higher holistic rating • Improvement on rate => improvement on rating Some positive results, but too small sample…
Study 2 Fall 2014 • Who? • Two volunteered second year Japanese students • Both are male. • What? • Treatment: weekly conversation table (two weeks: face-toface, two weeks: Google Hangout), Posting comment once a week • Assessment: pre/post-test free speaking task (few minutes about summer/fall break) • Holistic rating and temporal measures
Students’ reaction and reflection • (Unofficial survey) • Result…
Conclusion and suggestions • Relationship between: • written and oral production • Errors and fluency • Quantitative and qualitative analysis • Needs analysis • What and when do students want to do? • Most students requested more “speaking” practice in class. *informal survey showed that 90% were not interested or too busy for conversation table / extra curriculum activities. • Scheduling (increase/maintain participation) • Make use of chat history
