Background of the Problems Foreign students contribute about $13.5 billion to the U.S. eco
nomy each year through their tuition and fees and living expenses.
Every 31 seconds a new immigrant enters USA, but 60% are Limited English Proficiency (LEP) (Camarota, 2005).
47 million people speak language other than English, and 23 million people speak English less than “very well” (U. S. Census Bureau, 2005).
CALL programs has become a new solution for ESL education. Definition of CALL programs: An approach to language teachi
ng and learning, where the computer is used to assist the presentation, reinforcement, and assessment of the learning material (Davies, 2002).
Purpose of the Study
to gain a comprehensive understanding of the effectiveness of Computer Assisted Language Learning (CALL) programs on English as a Second Language (ESL) education for diverse English language learners and instructors
to provide the results as a reference to educational leaders and administrators who are considering the use of CALL programs for their English instruction programs.

Null Hypotheses
Significance of the Study May provide educational leaders and
administrators a view of the problems associated with current uses of technology in ESL education
May present an assessment tool that educational leaders and administrators may use to determine the degree to which technology investments are effective within specific populations
May encourage ESL instructors to adopt CALL programs as a viable educational alternative and inspire students to promote language abilities through the application of CALL programs
Research Methods
A combination of Quantitative and Qualitative research methods was utilized for the study
Research Methods (cont.)Quantitative TAM in CALL Questionnaire was modified from Davis’
Technology Acceptance Model Six language translation versions: English, Spanish, French,
Korean, Traditional Chinese, and Simplified Chinese. The response scale was a 5-point Likert scale which assigned
numerical values for each response:
Strongly Agree = 5 Agree = 4 Neutral = 3
Disagree = 2 Strongly Disagree = 1
Descriptive statistics were used to describe demographic data One-way ANOVA statistical method was employed to examine
the difference between LEP students’ individual backgrounds and their “Usefulness” and “Ease of Use” perceptions of CALL programs.
Research Methods (cont.)Qualitative Nine interview questions based on the
Customer Value Theory were asked during the interviews in order to identify:
1. Advantages and disadvantages of CALL programs
2. Roles of CALL programs in actual ESL classrooms
3. Expectations for future CALL programs
Data analysis included coding, generating categories, and writing interview summaries

English learner’s native language was a factor that yielded a significant difference in LEP students’ perceived “Usefulness” of CALL programs for enhancing English learning
Three reasons may contribute to the result:1. Digital Divide (
International Telecommunication Union, 2003)
2. Levels of English Proficiency3. Translation Versions
Discussion Null Hypothesis One
A student who lives in a higher Digital Access Index (DAI) scoring country may have more opportunities to get the benefits of computer technologies and the Internet, and can gain more opportunities to increase their individual computer literacy skills (International Telecommunication Union, 2003).
Students of varying levels of English proficiency in English do have differing perceptions of the use of technology (Doll, 2007).
Lower level of English proficiency students were enthusiastic about the CALL environment; higher level of English proficiency students need more significant learning inputs and might be difficult to perceive an improvement through regular CALL programs for their English skills (Hayes & Hicks, 2004)

Major FindingsResearch Question One (cont.)
To further examine the differences, a Scheffe test was conducted. However, there were no the mean difference between each age group and a p value shown in Scheffe test.
A Least Significant Difference (LSD) test was conducted.
The result yielded a significant difference between the following pairs of age groups:
1. “under 20 years old” and “31 to 40 years old” age groups (p = .002)
2. “under 20 years old” and “41 to 50 years old” age groups (p = .002)
3. “21 to 30 years old” and “31 to 40 years old” age groups (p =.001)4. “21 to 30 years old” and “41 to 50 years old” age groups (p =.002)
LEP student’s age range was a factor that caused significant differences toward students’ “Usefulness” perceptions when using CALL programs
Three reasons may contribute to the result:1. Generations 2. Levels of English Proficiency3. Duties According to the qualitative interviews, the older students
had to spend more time on their jobs and household duties. They had very little time for English study or computer use at home. This might account for some of the difference in “Usefulness” scores between age groups.
Discussion Null Hypothesis Three
The age difference could not be regarded as an influential factor affecting older adults engaging in Web-searching activities…….. If we can provide more trainings and opportunities to older adults, older adults may overcome the age difference and enjoy the benefits of computer technologies more than younger users (Kubeck, Miller–Albrecht, & Murphy, 1999) .

Discussion Null Hypothesis Six
Student’s native language and culture background may influence his or her perception regarding the use of computer technology for enhancing their learning (Zoe & DiMartino, 2000).
Through the qualitative interview, one ESL instructor pointed out that Asian students are often good at computer technology. Their countries usually have more technology infrastructure, so they can get more technology exercise opportunities.
The transfer of prior linguistic and cognitive knowledge from the first language to the second language is a requisite learning process for LEP students (O’Malley & Chamot,1990) .

Major FindingsResearch Question Three
What are the advantages and disadvantages of CALL programs in actual ESL teaching and learning?
CALL programs have a positive influence on their ESL teaching and learning.
Major Advantages:1. Increase access to authentic materials for teaching and learning
English2. Provide more opportunities for practice through experiential
learning3. Offer more varied learning situations that enhance learning
motivation and achievement. LEP students: more online interactive opportunities; more learning
resources.
ESL instructors: prefer the traditional face-to-face interactions. Focus on evaluation and record students’ learning progresses.
Major FindingsResearch Question Three (cont.)
Major Disadvantage ESL instructors: 1. may not totally align with beginning level English
learners’ needs;2. may reduce English learners’ opportunities to
explore other learning resources; and3. may increase the teaching and learning loads
LEP students: over-use of CALL programs may influence their spelling ability. The spell-correcting function of CALL programs may help to recheck their writing, but it may prevent them from learning to spell.
Related Literature Support
“The use of the computer does not constitute a method. Rather, it is a medium in which a variety of methods, approaches, and pedagogical philosophies may be implemented” (Garrett, 1991, p. 75).
No matter what many functions CALL programs provide, they are still no more than media for teaching and learning. The effectiveness of CALL programs does not lie in the medium alone but in how the programs are used and the quality of personal teaching and guidance that accompany them.
Major FindingsResearch Question Four What is the role of CALL programs in current ESL
instructions?Time spent on CALL programs: ESL instructors: 1. the length of the semester 2. the content of textbook
LEP students: technology experience backgrounds Without technology background or with little
technology knowledge, students spend little time or none on using technology to enhance their learning.
Students who have rich technology experiences often spend more than ten hours per day for using the computer and the Internet.

Major FindingsResearch Question Four (cont.)“Tool” role:1. vary their teaching and learning paths2. provide more interactive activities3. facilitate the effectiveness of teaching and learning.
“Tutor” role: CALL programs can offer reading, vocabulary, and other
kinds of practice to evaluate students’ works and keep their records.
“Tutee” role: Each student has individual learning needs and the computer
is not able to adapt to different learning styles of the student. CALL programs should follow and satisfy English learners’
needs.
Related Literature Support
Computers play various roles that deeply impact ESL teaching and learning methods (Warschauer & Kern, 2000; Wiazowski, 2002)
The theoretical framework underlying CALL programs is very difficult to define because CALL programs exist in so many different forms. The specific role of CALL programs often depends upon different needs and different situations (Kemmis, Atkin, & Wright, 1977; Higgins, 1988, Taylor, 1980).
Major FindingsResearch Question Five
What are the second-language learning efficiency expectations of LEP students and ESL instructors utilizing CALL programs?
Satisfaction of current CALL All ESL instructors: Current CALL programs are
good enough for ESL education. Four LEP students: CALL programs are not perfect
enough to meet their learning needs. (For example: Translation Function)
Major FindingsResearch Question Five (cont.)English skills can be improved effectively
A. The variety of CALL programs permits different users to address different learning goals and produce different learning results.
B. Because there are no solid guidelines and standards, some instructors and students become confused with the functions and abilities of
current CALL program.

Major FindingsResearch Question Five (cont.)
Expectations of future CALL programs:1. The price of computer, CALL software, and
Internet connection should be reduced
2. The future CALL programs should be easier to use “To beginning level learners, computers or CALL
programs are difficult to operate sometimes”
3. Should have more human intelligence to understand learners’ needs and can give students correct feedback immediately
Related Literature Support
Software of CALL programs is still imperfect, and their functions are limited. Due to the limitations of computer’s artificial intelligence, current computer technology is unable to deal with learner’s unexpected learning problems and response immediately as teachers do (Warschauer, 1996).
The reasons for the computer’s inability to interact effectively can be traced back to a fundamental difference in the way humans and computers utilize information (Dent, 2001).
Conclusion
LEP students come from different countries and have distinct learning habits and attitudes toward the use of technology for enhancing English learning. It is important that educational leaders and ESL instructors pay greater attention to students’ personal factors and their learning needs.
When investments in CALL programs are made, it is important that the CALL programs be useful and easy to use for all populations served. Failure to evaluate CALL applications continuously and to make improvements in the development and deployment of CALL software can result in non-use or ineffective use.
Conclusion (cont.) Lack of technology knowledge is a major barrier to
realize the advantages of CALL programs. Educational leaders and administrators should face the problem and develop technology training plans to ensure that all ESL teachers and LEP students have the knowledge and skills to apply CALL programs in their teaching and learning.
To identify what role CALL programs played in the
classroom is important because each instructor’s and student’s perceptions of the roles of CALL programs will further influence their decisions on how to apply CALL programs in their language teaching and learning.
Conclusion (cont.)
To overcome the price problem and ensure each student has the equal opportunity to get CALL programs for enhancing their English Learning, educational leaders and administrators may have to negotiate with computer producing factories and software companies to reduce the selling prices of computers and CALL software.
To improve the artificial intelligence and the ease of use problems, educational leaders and administrators may have to communicate with software designers to design more appropriate CALL programs for ESL teaching and learning.
Recommendations for Further Study
A study could be conducted at the state level or national level.
A study could be conducted that focused on the same student’s English level.
A study could be conducted that focused on specific software of CALL program.
A study could be conducted of the student’s learning style associated with CALL programs.
A study could be conducted of the effectiveness of pedagogies associated with CALL programs.
A study could be conducted of the curriculum design associated with CALL programs.
A study could be conducted of the students’ learning achievements associated with CALL programs.
Recommendations for Further Study (cont.)
A study could be conducted to address different learning goals that produces different results.
A study could be conducted to focus on more human intelligence of CALL programs to understand the language learners’ needs.
A study could be conducted on personal factors related to students’ learning needs and personal circumstances.
A study could be conducted on how educational leaders and administrators can develop policies and strategies that will support more effective and efficient systems for purchasing and maintaining CALL applications that will assist English teaching and learning.
Recommendations for Further Study (cont.)
A study could be conducted on how educational leaders and administrators can develop and implement training plans to ensure that all ESL teachers and students have the knowledge and skills to apply computer technology in their teaching and learning.
A study could be conducted about the role of computer technology within the context of the second language instruction.
A study could be conducted that specifically focuses on the three major barriers: price, artificial intelligence, and ease to use.
A study could be conducted on ways technology has become a powerful force in education.
