Fraser,Reading Rate in L1 Mandarin Chinese and L2 English Across Five Reading Tasks,Topics to be covered,Research questions Variables Justification of the current study,Research questions,Q1:Is there a difference in reading rate (L1 vs. L2) for each of the five tasks? If so, the same across all the tasks? Q2:Is there a difference (L1 vs. L2) in task performance on the scanning, skimming, learning and memorizing tasks? Q3:Are there group differences (Canada group vs. China group)?,Variables,Independent variables,Control variables,Moderator variable,Dependent variables,Task types,Language types,Group types,Independent Variables,Learning,Scanning,Skimming,Rauding,Memorizing,Canada Group,China Group,L1(Chinese),L2(English),normal reading,Moderator variableL2 proficiency,Examine the impact of L2 proficiency on L2 reading rate and task performance, The listening scores of CELT used as a covariate,Variables,Independent variables,Control variables,Moderator variable,Dependent variables,Reading rate reflecting reading fluency: an important issue for many ESOL students.,English speakers of other languages,Justifications,Justifications,A considerable gap in L1/L2 reading rates for the majority of L2 readers Difficult to interpret the extent and significance of the observed L1/L2 reading rate gap Little research done on the nature of the reading performance behavior among L2 learners,Justifications,Little research done on the relationship between the reading rates and reading performance Previous studies on reading rate confining to one task type,Some related terms,Reading fluency Hierarchy of five tasks,Reading fluency,“The ability to read text rapidly, smoothly, effortlessly and automatically with little attention to the mechanics of reading such as decoding” (Meyer, 1999, p. 284).,Research design,Participants Measures Procedures Data collection Questions,Participants,Native speakers of Mandarin Chinese Learning English as an L2,14+27 45 Much greater variability within the Canada Group than the China Group,Measures,CELT: Form A, listening portion 10 short expository texts from TOEFL Various measures used to match the difficulty level of the passages Microsoft word 2000 counts, average, readability statistics Performance measures of five tasks:,* Can the listening portion alone test the language proficiency on the whole?,Performance measures,Data Collection,Two Phases: CELT scores L2 proficiency Research booklets of tasks reading rate and task performances,The order counterbalanced,The order of presentation was counterbalanced for both language (L1 or L2) and passage (PA or PB),Task 1 A B L2A L2B L1A L1B,L1A L2B L2B L1A L2A L1B L1B L2A L1A L2B L2B L1A L2A L1B L1B L2A,Data analysis,Descriptive statistics A repeated measures ANOVA (单因素重复测量方差分析）used to compare the reading rates and task performance of the two groups of native speakers of Mandarin Chinese in their L1 and L2 across five different reading tasks A repeated measures ANCOVA(单因素协方差重复测量分析) applied to the L2 rate variables and multivariate ANCOVA（多因素协方差重复测量分析） applied to the performance variables,Results,Measures on Reading Rate (Table 1) Repeated measures ANOVA applied to compare L1 to L2 reading rates across the five tasks (Table 2),Q1: Is there a difference in reading rates (L1 vs. L2 for each of the five tasks?,In general, the task rates in both the L1and L2 reading conditions followed the faster to slower hierarchy The Chinese participants in this study read faster in the L1 (Chinese) condition than in the L2 (English) condition on all five tasks.,The differences or changes in reading rate from L1 to L2 passages were for the most part not the same between tasks. There was more change in reading rates between pairs of tasks in the L1 than in the L2.,Q1: Is this difference the same across all tasks?,Higher scores on the performance measures in their L1 than their L2 tasks except the multiple-choice questions attached to the learning task Greatest differences between L1 and L2 performance measures in the skimming and memorizing tasks,Q2: Is there a difference (L1 vs. L2) in task performance on the scanning, skimming, learning and memorizing tasks?,Q3: Are there group differences in reading rate?,The Canada group had less difference in L1/L2 reading rates than the China group. The China Group read faster on all L1 reading Tasks than the Canada Group.,Q3: Are there group differences in task Performance across four reading tasks?,The China group had higher scores than the Canada group on all measures except the L2 recall task. The Canada group demonstrated a much smaller difference in their L1/L2 recall scores than the China group.,Problems in design,Independent variables Language types Task types Group types Language proficiency,Problems in design,Dependent variables Reading rate Performance measures,Problems in writing: title,Reading rate and task performance In L1 mandarin Chinese and L2 English Across five reading tasks.,Problems in writing: Structure,Literature review Method participants measures procedures research design research question data analysis & results Discussion and conclusions,Literature review Research question Research design Participants materials Data collection Data analysis Results and discussions Conclusions,Results,Performance measures for the two groups (Table 3) (An error in the time of the table) Repeated measues ANOVAs applied separately to each of the four pformance variables to compare L1 to L2 performance (Table 4).
