CALL, which is defined as computer-assisted language learning, is surely related to ICT, information communication technology. There are many uses of computer in the classroom or at home. Computers should be used as language learning tool— just as any other pieces of equipment (i.e., tape recorder, VCR, black board, books etc). Hartoyo (2006, 11) says that “A computer as a medium is used for the sake of facilitating people in learning, such as learning a language.” It is important that computer not become the center of attention of the lesson. There are situations when activities at the computer can become the center of attention; however, this situation should be avoided and left to the students to decide when, and if, they want to utilize such activities (in-self access). For some tasks, computers can provide distinct advantages over more traditional approaches. Students interacting with a computer are also using their motor skills as well, which can have a strong reinforcing effect on the learning process by connecting physical actions (clicking, typing) with desired result. Students are also allowed more control over their own learning process as they make the decisions when to repeat questions, exercise and sequences based on their own progress. But with CALL software, there is always one nagging question: What can the software do that can’t be done just as well with a book, pencil and paper? A good CALL program should allow the user to work more efficiently and to accomplish tasks and obtain information that would be difficult or impossible to do in a more traditional mode. CALL can help student enhance their TOEFL score efficiently. Nowadays, many universities have applied their policy to the students who will graduate to meet certain TOEFL score. It is one of the prerequisites that they have to fulfill; otherwise, they cannot graduate. TOEFL score is also important for students who want to pursue their further education abroad or to pursue their master’s degree at local universities. Studying TOEFL is not an easy job because it needs extra efforts to achieve a certain score. Besides, someone who wants to get sufficient score must be at least in higher intermediate level. As we know English is not our second language. It is our foreign language. This is one of the reasons why there are many students encounters some difficulty to do this test. Even though there are many TOEFL books available in the book stores and many English courses which offer TOEFL program, some students still have some problem to do it. The questions in the TOEFL test are very tricky. Students must have extensive vocabulary and thorough understanding of grammar points because the grammar used in TOEFL is advanced grammar. One way to practice TOEFL is using practice TOEFL books with the cassettes for listening; however, using computer with CD TOEFL practice software is more effective than using TOEFL books and cassettes because of several reasons. In this paper, I only focus on Paper-Based TOEFL test (PBT) which is widely used in universities in Indonesia, and I also talk about the advantages and disadvantages of using computer and TOEFL practice book to increase TOEFL score. Before talking about the effectiveness of using computer to enhance students’ TOEFL score, I’d like to talk more about TOEFL.
WHAT IS TOEFL?
TOEFL is an acronym that stands for Test Of English as a Foreign Language. It measures test takers’/students’ proficiency in the English language in an academic context. Most universities and colleges in the US, Canada, and post graduate programs in Indonesia require students to take the TOEFL test if students want to apply for a place to study there, and in Indonesia TOEFL score is also used to meet one of the requirements to graduate from universities (as mentioned above). In many countries nowadays, IBT (Internet-Based Test) — the latest form of TOEFL test— is used to measure students’ proficiency. This means that students have to follow, do the test, and answer the questions interactively from the computer just as in Computer-Based Test (CBT).
At the moment there are three versions of the tests, depending on which part of the world the test is taken. In Indonesia, TOEFL tests are still Paper-Based Tests which consist of the following disciplines: reading, listening, and writing. If students want to score high marks in all three sections, their English should be sufficient to take the tests. The three versions of the TOEFL tests are:
1. The traditional Paper-Based TOEFL test (PBT)
2. The computer-Based TOEFL tes (CBT)
3. The Internet-Based TOEFL test (IBT)
I. The traditional Paper-Based TOEFL test(PBT)
The examination lasts for approximately two hours. It is divided into three sections:
Section 1. Listening comprehension (35 minutes – 50 items)
Section 2. Structure and written expression (25 minutes – 40 items)
Section3. Reading comprehension (55 minutes – 50 items)
TOEFL scores for each section are reported on a scale that can range from 31 to 68. The scores are then scaled to give the total score. TOEFL total scores are reported on a scale that can range from 310 – 677.
II. The Computer-Based TOEFL test (CBT)
At the beginning of July 1998, the Computer-Based TOEFL test was introduced in certain areas of the world. The Computer-Based TOEFL has four sections: Listening, Structure, Reading, and Writing. The Computer-Based test is reported on a new score scale. This new score scale has been designed to distinguish score received on Computer-Based TOEFL from those received on the Paper-Based test. For the Computer-Based test, the examinee receives four scaled scores: Listening (0 to 30), Structure/Writing (0 to 30), and Reading (0 to 30), and total score (000 to 300). The three section scores and a total score are reported on the score report. The essay rating is integrated in the Structure/Writing score; in addition, the score on the essay is reported as an independent rating on the report.
III. The Internet-Based TOEFL test (IBT)
In September 2005, the TOEFL test changed in significant ways. The Internet-Based TOEFL test measures all four skills of communication: Reading, Writing, Listening, and for the first time Speaking. It also uses questions that ask students to combine their skills to show how well they can use English to communicate. As a result of these changes, TOEFL has established a new scoring scale of the test. Score reports will contain five different scores: one total score on a scale of 0-120, and four skill scores, each on a scale of 0-30. Scores from the new TOEFL test provide information about performance in the four skill areas students need for success in an academic environment. Listening 0-30 Reading 0-30 Speaking 0-30Writing 0-30 Total Score 0-120 Correlation between Paper-Based TOEFL scores, Computer-Based TOEFL scores and Internet-Based TOEFL (IBT):
Paper-Based TOEFL 450 477 500 527 550 577 600
Computer-Based TOEFL 133 153 173 197 213 233 250
Internet-Based TOEFL 45 53 61 71 80 91 100
As we know, TOEFL score is not only needed by students to graduate from their universities or to pursue their further education abroad or local universities, but also by private or state-owned company employees to get promotion or to get scholarship from their offices. There are three sections in Paper-based test: Listening, Structure, and Writing. I’ll analyze one by one why using computer CD is more effective than using books and cassettes.
Listening
Listening practice comprises of three sections: short conversations (30 questions), longer conversations/ talks (1-8 or 10 questions), and long talks/ lectures (10-12 questions). The most difficult part is the last one (long talks/ lectures), then longer conversations. If students are not used to listening to native speakers talking, they surely have some problem to do it because the topics of the talks are long, and the speaker talks fast. Test takers listen to the conversations only once, so if they miss the conversation or talks, they will have some difficulties to answer the questions.
To practice listening section, test takers/ students may use books and cassettes or CD software available in book stores or computer software stores. Using CD software is an effective way to improve their listening skills because of the clarity of the conversation/ talks and the availability of the feedback. As we know that computers use digital technology while tape recorders use analog technology. The quality of the voice produced by computers is much better that that of tape recorders.
After finishing doing the test/ the practice, the students can get the feedback directly from the computer. For the Listening section, each of the “Description” sections presents a thorough explanation of the different item types normally encountered on a TOEFL exam with a sample item that may be played and practiced. Each of the “Practice” selections leads to a long set of practice items. When “Play Dialog” is clicked a QuickTime control panel pops up which permits the student to replay the dialog in part as many times as required. Once the correct answer has been selected, a box explains why the other choices were wrong. They can do it several times easily.
Computers will also tell the users/ students their specific weaknesses that they have to give more attention to them. When they use a cassette, they have to rewind it several times, and it is very time-consuming. They can also read the conversation/ tape script at the last page of the book. Using computer CD is very effective way to improve the students’ ability to understand the conversations especially for beginners who try to improve their TOEFL scores. CD TOEFL software also provides excellent listening comprehension activities, given a good listening guide prepared for the students. Depending on the language level, students listen for just the main idea or a segment, or they listen for specific facts in the program.
Besides some advantages as mentioned above, there are also some disadvantages of using computer CD. The prices of original CD are expensive, and to get excellent voice needs a sophisticated computer meaning more money to spend. In term of the effectiveness, practicing listening through the computer is excellent. When using books to practice TOEFL, students especially in the lower level will also get an advantage because they can read the tape script beforehand, so they will feel more comfortable to do the practice. The listening feature using CD, however, is superior to the non-tech alternative of using a text with a cassette tape since it is much easier to find and repeat specific passages.
Structure/ written expression
This part consists of a number of various choice questions that test students/ test takers knowledge of the structure of English sentences and error recognition questions that test their knowledge of correct written expressions.On the Paper-based test, there are two types of questions: structure and written expressions section.
1. Structure (15 problems, from number 1-15) comprises of fifteen sentences. Each part of the sentence has been replaced with a blank. Each sentence is followed by four answer choices. Test takers must decide the answer that completes the sentence in a grammatically correct way.
2. Written expression (25 problems, from number 16-40) comprises of twenty-five sentences. There are four words or groups of word have been highlighted. The test takers must choose the highlighted words or groups of words that is incorrect.
Paper-based test questions are presented in linear order. Questions number 1 to 15 and questions number 16-40 progress from easy to difficult. The score is based on the answer of these forty questions.
Structure and written expressions might be the most difficult part for students who take the TOEFL test because the questions are very tricky and unpredictable. It needs thorough understanding of sentence structures, and there are also some tips to do this part. Practicing structure and written expression from CD is effective. The practice is arranged in linear order. It will start from the easiest one to the most difficult test, and the feedback is also available. After finishing doing the practice, the computer will show the test result automatically. It also shows the mistakes that the students made. Students can review the test by checking the right answers. Before doing the practice test, it is advisable that students study the strategies to answer the questions. In Longman TOEFL test, there are 55 skills/ strategies that will help students to implement the strategies and procedure in the structure questions. Each skill is also graded from a simple one to a complicated skill. Unfortunately, beginners will have some problems if they study and practice the structure section only from CD because the explanation of the grammar points is very simple and short. Questions on grammar section are very tricky and complex. It needs a thorough explanation to be successful to answer them. It is advisable that beginners do not spend time puzzling out the feedback on their answers since the explanations are often unsatisfying. Using books will be more effective for beginners because they will find more thorough explanation, but for advanced learners, studying structure from CD is more challenging and effective because the activities provided are varied.
Reading
This section is designed to measure the test takers’ ability to read and understand short passages similar in topic and style to those found in North American universities and colleges. They read a variety of short passages on academic subjects. Each passage is followed by a number of questions about the material. To avoid creating an advantage to individuals in any one field of study, sufficient context is provided so that no subject-specific familiarity with the subject matter is required to answer the questions.
On Paper-Based test TOEFL, the third section is called reading comprehension. This part consists of 5 passages and fifty questions (although some tests may consist more). Test takers have fifty – five minutes to complete the fifty questions in this section. There is only one type of question in the reading comprehension section of the paper TOEFL test, namely, Multiple-choice questions. The questions on the Paper-Based test are presented in linear order, just like in the previous sections listening and structure. The passages progress from easy to difficult, and the questions are presented in the order in which they appear in the passage.
There are some advantages that students get when practicing reading section. When they encounter some difficult words on the passage(s) while doing the practice test, they can use the dictionary in their computer by clicking the words, and the translation will appear. (Of course, it depends on the feature of their computer. The more sophisticated the computer is, the more features available in it). Using computers offers freedom for users to choose any topic in the TOEFL reading practice test they may choose any topic in the practice test that interests them.
Besides those advantages, there are also some disadvantages .When practicing the tests, the user can return to previous items by laboriously clicking “back” In the Reading Comprehension section, even though the questions for each passage generally proceed in order from beginning to end, each new item resets the reading passage to the top, forcing the test-taker to scroll down again to the relevant section. Reading a long passage from the computer is slower, more difficult, and tiring while using books is more convenient because books are small enough to be carried out, so students can do the reading practice whenever and wherever students wish In conclusion, from the explanations above, the effectiveness of using computer to enhance students’ TOEFL score is more dominant than that of TOEFL books/cassettes even though there are also some disadvantages.
Some more advantages that students get from using CALL to improve their TOEFL score:
· The computer adds variety of TOEFL exercises for students.
· The computer individualizes learning. The learner is not dependent on other members of a class, but can choose the pace at which he or she progresses, control the degree of difficulty (e.g., by leaving out elements which are too easy or too difficult), decide whether and how often to repeat an exercise, and so forth.
· Study material on CD-ROM /software holds great promise since more information can fit on one disk than could fit in an entire book.
· In CALL TOEFL exercises, the computer can give immediate feedback for each answer.
· Using the computer can save teachers time and work, with routine marking, for example, that can then be used for more creative aspects of language teaching such as, giving more explanation to the students who have some difficulty in their lesson. (Thus benefiting the learner).
· CALL is a helpful environment for student-computer interaction.
· Students are motivated to use the computer for all types of activity.
Besides, the advantages there are also some disadvantages of using CALL:
· The prices of original TOEFL soft ware are expensive.
· Learners must have computers. They can use computers at school, but the opening hours are very restricted.
Some advantages of using books and cassettes to practice TOEFL:
· Practice grammar and structure books in TOEFL give more thorough explanation than TOEFL CD soft ware, and it is more beneficial for students in lower level.
· Books are small enough to be carried around and studied wherever and whenever students wish. ( Ansel, et al, 1992).
· Students don’t have to spend a lot of money to buy sophisticated technology: computer, CD ROM/ soft ware.
The disadvantages of using books/ cassettes to practice TOEFL:
· Using cassettes to practice listening test in TOEFL is considered to be much less handy because the quality of the voice from CD ROM is much better that of the cassettes.
· In books/ cassettes exercises, they cannot give immediate feedback for each answer.
· The practice is not as varied and challenging as the practice in CD TOEFL soft ware.
