  1. TBLT 2, Hawai’i The influence of strategic task based planning on the fluency, accuracy and complexity of speech in two L2s. Siska Van Daele, Alex Housen & Michel Pierrard ACQUILANG (Centre for Studies on Second Language Learning & Teaching)

  2. BACKGROUND • Exploratory longitudinal study of theComplexity, AccuracyandFluency (CAF)of the L2 speechproduced byDutch-speaking adolescents learning French and English as FLs(and by native speakers of French and English).

  3. AIMS • Describe the development of productive oral proficiency in two L2s in terms of Complexity (C), Accuracy (A) and Fluency(F) and the factors that influence the manifestation of CAF. • FormulateconstructdefinitionsandoperationaldefinitionsofComplexity, AccuracyandFluencyas basic dimensions of L2 proficiency. • Information processing theoriesand psycholinguistic models of speech production(e.g. Anderson 1993; Bialystok 2001; De Bot 1992; Ellis 1994, 2004; Levelt 1989; 1999; MacLaughlin & Heredia 1996; Robinson 1995, 2003; Skehan 1998).

  4. C-A-F in L2 is influenced by: 1. Cognitive & Psycholinguistic factors: • working memory capacity • attention 2. Psychological factors: • Affective factors (eg. attitudes, motivations…) • Personality factors (eg. extraversion, degree of foreign language anxiety…) 3. Contextual factors: • amount and type of contact with L2 • task type and planning conditions

  5. THEORETICAL FRAMEWORK L2 CONSTRAINTS: • limited lexicon • limited processing capacity PLANNING: • types: • (strategic) pre-task aids F & C • within-task aids C & A • increases processing capacity (Levelt, 1989)

  6. THEORETICAL FRAMEWORK PREVIOUS RESEACH: • positive results for fluency & complexity (Crookes, 1989; Foster, 1996; Foster & Skehan, 1996; Mehnert, 1998; Ortega, 1999; Skehan & Foster 1997; Wendel, 1997 and Yuan & Ellis, 2003). • no (Crookes, 1989; Wendel, 1997; Yuan & Ellis, 2003)or mixed results (Foster, 1996; Foster & Skehan, 1996; Mehnert, 1998; Ortega, 1999; Skehan & Foster1997) for accuracy. • DUE TO: • unintentional within-task planning(Yuan & Ellis, 2003). • length of preparation time (Mehnert, 1998). • learner strategies (Ortega, 2005). • type of planning(guided/non guided),task(narrative, decision making…) (Foster & Skehan, 1996; Skehan & Foster, 1997; Sanguran, 2005). • proficiency level(Kawauchi, 2005, Ortega, 1995, 1999, 2005). • language typology

  7. RESEARCH QUESTIONS • DESCRIPTIVE QUESTIONS PLANNING: • 1. a. Does unguided strategic pre-task planning have an effect on the fluency, accuracy and complexity of intermediate English-FLlearners? b. Does unguided strategic pre-task planning have an effect on the fluency, accuracy and complexity of THE SAME intermediate French-FL learners? 2. Are the effects of unguided strategic pre-task planning similar or different for both target languages?

  8. METHODOLOGY • PARTICIPANTS: • L2 learners: • 40 Dutch-speaking adolescent learners (aged 14-16) of EFL and FFL in secondary education in Flanders. DESIGN (cross-sectional and cross-linguistic):

  9. Foreign Language Teaching and Learning in Flanders: • L2-French (= other national language): • Starts at age 8-9 (Year 3) • Taught for 3-5 hrs a week (till Year 12) • ± 360 hrs classroom contact at start of study (Year 9) • L3-English: • Starts at age 12-13 (Year 7) • Taught for 2-4 hrs a week (till Year 12) • ±180 hrs classroom contact at start of study • similar curricula + same (expected) levels of FL-achievement for FFL and EFL (in Years 9-11)

  10. METHODOLOGY MATERIALS & DATA: • Oral retell-task: 3 versions of a 60-frame wordless picture story: Monsieur O (L. Trondheim): variations on a similar general plot line, same protagonist and contextualization but different secondary characters.

  11. METHODOLOGY MATERIALS & DATA: • Task conditions:participants told the story with and without pre-task planning time (5. min - 0 min.) and under time pressure (max. 5 min). • Oral speech data: recorded and transcribed and analyzed in CHAT-format. • Statistical analysis: three-way random effect ANOVA’s.

  12. METHODOLOGY • C-A-F MEASURES • COMPLEXITY: • Lexical Diversity: Guiraud’s Index (e.g. Vermeer, 2000). • Syntactic Complexity: Subclause ratio(Wolfe-Quintero, Inagaki & Kim, 1998). • ACCURACY: • Lexical Accuracy: lexical errors per clause • Grammatical Accuracy: morphological + syntactic errors per clause (Wolfe-Quintero, Inagaki & Kim, 1998). • FLUENCY: • Speech Rate A & B ((meaningful) syllables per minute) (e.g. Yuan & Ellis, 2003; Ellis & Yuan 2005).

  13. HYPOTHESES • EFL & FFL speech under the +P condition will be characterized byhigher fluency rates>(pre-task) conceptualizationreduces hesitation/pausing behavior. 2. EFL & FFL speech under the +P condition will be syntactically more complex and lexically more diverse> allocation of attention to message construction in conceptualizer and formulator. 3. EFL & FFL speech under the +P condition will be grammatically and lexically more accurate > advanced (and intermediate ?) learners can attend to semantic and syntactic encoding AND monitor their output.

  14. HYPOTHESES • EXPLORATORY RESEARCH QUESTION: • Are the effects of planning influenced by language typology and is this effect independent of other variables such as proficiency level?

  15. RESULTS: FLUENCY Sig. increase in Eng (F 1,38=6.91, p=0.012) Near-sig. increase in Fr (F1,38 =3.57, p=0.067) Eng > Fr in both conditions & for both measures (F 1,115=316.63, p= <0.0001)

  16. RESULTS: COMPLEXITY Sig. increase in IG & SCR in Eng (F1,38=4.77, p=0.035) Sig. increase in IG & SCR in Fr (F1,38=4.77, p=0.035) Eng > Fr in both conditions & for both measures (F1,115=316.63, p= <0.0001)

  17. RESULTS: ACCURACY Sig. decrease in errors in Eng (F1,38=8.72, p=0.005) No sig. change in Fr (F1,38=0.00, p=0.983) Eng > Fr in both conditions & for both measures (F1,116 =121.27, p=<0.0001)

  18. SUMMARY & DISCUSSION Does unguided strategic pre-task planning have an effect on the fluency, accuracy and complexity of intermediate English-FL and the same French-FLlearners? Are the effects of unguided strategic pre-task planning similar or different for both target languages?

  19. SUMMARY & DISCUSSION 1. EFL & FFL speech under the +P condition will be characterized byhigher fluency rates>(pre-task) conceptualizationreduces hesitation/pausing behavior.

  20. SUMMARY & DISCUSSION 1. EFL & FFL speech under the +P condition will be characterized byhigher fluency rates>(pre-task) conceptualizationreduces hesitation/pausing behavior.

  21. SUMMARY & DISCUSSION 2. EFL & FFL speech under the +P condition will be syntactically more complex and lexically more diverse> allocation of attention to message construction in conceptualizer and formulator.

  22. SUMMARY & DISCUSSION 2. EFL & FFL speech under the +P condition will be syntactically more complex and lexically more diverse> allocation of attention to message construction in conceptualizer and formulator.

  23. SUMMARY & DISCUSSION 3. EFL & FFL speech under the +P condition will be grammatically and lexically more accurate > advanced (and intermediate ?) learners can attend to syntactic and semantic encoding AND monitor their output.

  24. SUMMARY & DISCUSSION 3. EFL & FFL speech under the +P condition will be grammatically and lexically more accurate > advanced (and intermediate ?) learners can attend to syntactic and semantic encoding AND monitor their output.

  25. SUMMARY AND DISCUSSION Are the effects of planning influenced by language typology and is this effect independent of other variables such as proficiency level? • Unexpected discrepancy in proficiency levels: typology (???) • BUT: At higher proficiency levels (EFL): gains in accuracy

  26. Limitations & implications for further research • Measurements of CAF as basic dimensions of L2 proficiency: • QUANTITATIVE ANALYSIS • more and more fine-grained measures (e.g. repair/breakdown F) • factor analysis > interplay between dimensions (Tavakoli & Skehan, 2005) • OTHER METHODS: • developmental sequences (Bartning & Schlyter, 2004; Pienemann, 2005) • qualitative analysis (e.g. pausing behavior, word difficulty) (Chambers, 1997) • chunks/ formulaic sequences (Stengers, 2006)

  27. Limitations & implications for further research • Crosslinguistic analysis (typology): • proficiency test / pre-test • consider typological differences in phonology / inflectional morph. • Effects of strategic planning • individual variability: • strategies think aloud protocols (Ortega, 1995, 1999) • personality/ affective variables • length of planning and execution (Mehnert, 1998, Ellis & Yuan, 2003) • task type / complexity (Tavakoli & Skehan, 2005;Robinson et al.,1995) • type of strategic planning: guided >< non guided(Sanguran, 2005)
