2. A Comparison of the Usage of English Tenses of Undergraduate Students with Different Abilities Receiving Different Types of Error Treatment through the Use of CALL Somsri Jansom The 2006 International Symposium of CALL June 2-4, 2006, Beijing www.hcu.ac.th www.chula.ac.th

3. Applying CALL to Teach Grammar in Large Classes Why CALL? How? The program No final results

4. Introduction: Previous Research Most frequent technique used is teacher correction TC does not establish a pattern for long- term memory Self-correction should be promoted for greater retention

5. Theories Constructivism “ Learners can construct their own knowledge. ” Learners should be engaged more actively in their learning. Noticing Hypothesis (Schmidt, 1990) “ Noticing is the process of attending consciously to linguistic features in the input. ” Autonomous Learning Ultimate goal Congruent with the Goals set by the Ministry of Education of Thailand

6. Why CALL? The implementation in natural setting is uneasy 1. class size 2. learning habits 3. levels of the students Soinam (1999) : students with high English proficiency level had sig. different attitudes towards Autonomous Learning. 4. research: difficult to control responses, analyze data, and give consistent feedback

7. Advantages of CALL privacy individualization Data collection, Examination, & Manipulation controllable responses unbiased tireless & consistence

8. Disadvantages Operates in a predetermined fashion, can’t cope with the unexpected. Time-consuming to develop More tiring to read on the screen (Kenning & Kenning, 1983)

9. Research Questions 1. Are there any differences between the usage of English tenses of undergraduate students receiving Overt correction and Self-correction? 2. Is there any interaction effect of types of error treatment and levels of achievement on the usage of English tenses of the students? 3. What are the students’ opinions towards each type of the error treatment?

10. Research Objectives 1.To compare the usage of English tenses of students receiving Overt correction and Self- correction. 2.compare the retention of the usage of English tenses of students receiving Overt correction and Self-correction. 3.To compare the usage of English tenses of students with different abilities. 4.To study the interaction effect of error treatment types and levels of the students on the usage of English tenses. 5.To see opinions of students with different abilities towards each type of the error treatment

11. Hypotheses 1.The mean score from the immediate posttest of students receiving self-correction is significantly higher than that of the students receiving overt correction. 2.The mean score from the delayed posttest of the students receiving self-correction is significantly higher than that of the students receiving overt correction. 3.There is an interaction effect of error treatment types and levels of the students on the usage of English tenses at 0.05 significant level.

12. Scope of the study 1. Population: English-major undergraduates of Huachiew Chalermprakiet University 2. Two independent variables 2.1 Error treatment type: Self-correction (SC) and Overt correction (OC). 2.2 Levels of the students: High, Moderate, and Low Achievers. 3. The dependent variable: The usage of English tenses

13. Design and Methodology Sampling technique: 1.Stratified random sampling for 216 students (54 from each year) 2.Pretest and Labeling using percentile rank 3.Matching and Random assignment to OC or SC 4. Using t-test to assure that mean scores of OC and SC are not sig. different. P 30 P 70 LAHAMA

14. Design and Methodology Randomized Block Design Random selection + Random assignment Overt Correction Self-Correction LA MA HA

15. Experimental Materials Two CALL programs representing two different error treatments 1. Overt correction 2. Self-correction A Storyboard.docA Storyboard.doc Drill and practice 9 Modules, each takes around half an hour to complete Contents: 7 English tenses Practice Your Tenses DEMO_2.0.exePractice Your Tenses DEMO_2.0.exe

16. Research instruments 1. The Test of English Tenses Usage(TETU) 1.1 A sentence completion task (20 items) 1.2 Grammar in context (20 items) 1.3 A guided writing (2 prompts, 10-12 sentences each) 2. The Opinionnaire: numerical Likert-type scales, * The test will be conducted through a traditional paper and pencil mode

17. Data Collection Procedure Pretest Practice with CALL 9 modules, 5 weeks Posttest & Opinionnaire Delayed posttest (4 wks later)

18. Data Analysis Two-way ANOVA Descriptive statistics Thank You for your attention.
