The Effect of Using Internet-based Project Work toward Students ’ Vocabulary Mastery

In this age of globalization, an increasing number of individuals are studying foreign languages, particularly English, as a means of communication. Students noted several difficulties in learning English, particularly in learning vocabulary. Kids usually comprehend the professors' explanations, but it appears that most of the material will fade fast, particularly for junior high students who have several topics to study. Vocabulary is one of the linguistic components that students should acquire so that they may study the English subject effectively.Therefore, teachers need to design methods and strategies in teaching learning process. The research aims to investigate the use of Internet-based Project Work in supporting vocabulary learning. The results showed that the mean of total scores of students’ vocabulary mastery before being taught using Internetbased Project Work was 72,51 compared to the score after being taught using Internet-based Project Work which was 83,16. Based on the results, alternative hyphotesis (Ha) which states that there is significant different score of student’s vocabulary mastery by using Internet-based Project Work is accepted, while the null hyphotesis (Ho) that states there is no significant different score of student’s vocabulary mastery is rejected. Finally, it can be concluded that Internet-based Project Work is an effective strategy in teaching English vocabulary to junior high school.

A language teacher should have the ability to select a suitable method when teaching the students in order to make the students motivated to learn more and achieve a good score. There are so many options that can be used to teach vocabulary. Internet-based Project Work is one of the techniques that can be used in teaching English. This learning technique makes the students understand the English subject actively, independently and fun. Internet-based Project Work makes students enjoy in learning vocabulary and they will get active in teaching learning process by browsing and looking for the vocabulary independently. By applying the Internetbased Project Work, the students' vocabulary will increase.
Previous studies have pointed out the huge benefit of the internet in language learning and language teaching. For example, Chun and Plass (2000) outline broad capabilities of the internet characteristics that have the potential to improve language acquisition. Those characteristics are the worldwide availability of authentic resources, communication capabilities through networking, multimedia capabilities, and the hypermedia structure.
According to Gu (2010), several strategies for learning vocabulary in secondary school included primarily reading textbooks, listening to the teacher, and taking notes, whereas university students reported a much larger repertoire with more opportunities for use, such as writing essays, listening to radios, and conversing with English teachers and native speakers. Some techniques of language acquisition remained very consistent. These included classroom responsibilities such as listening to the teacher and taking notes. Vocabulary memorizing was the most widely used approach outside of the classroom.
In this research, researcher uses Internet-based Project Work as a fun media and simple because the material or topic can be searched quickly and accurately. To determine the students' vocabulary mastery, the researcher use vocabulary assessment as follows : Multiple-Choice Question Formats, MCQ Item Writing Tips , Matching Formats, Matching Item Writing Tips, Sentence Completion or Gap Fill Items , Translation ( Coombe, Folse, & Hubley, 2007 ). The researcher conducted research in class VIII-B because it was recommended from English teacher. Researchers want to know the effect of using the Internet-based Project Work as a media of teaching vocabulary to the students.
Through internet-based project work, students are more active and interactive way to learn vocabulary. By using this technique, students will find it easier to find the source of the material or topic. After that the students were able to present the results obtained in the classroom using a laptop and LCD or directly.

Method
This research was conducted by using an experimental research design. Experimental research is a scientific investigation in which the researcher manipulates one or more independent variables, controls any other relevant variables, and observes the effect of the manipulation on the dependent variables (Ary, et al, 2002). In this study the researcher just takes one group and use pre-test and post-test to see the result of the treatment and the population were all of eight grade of SMPN 1 Durenan consisted of eight classes : they are class A, B, C, D, E, F, G and H. Each of class consists of 31-32 students'. The researcher choose VIII-B consisted 31 students as a sample of this research.
A variable is a concept or a feature that can have varying values or scores (Ary et al, 2002). Variables can be categorized in a variety of ways.
Independent variables (X) are factors that are caused by or have an effect on dependent variables. In this research, the vocabulary is studied utilizing Internet-based resources. Project Work as media is independent variable and to dependent variable (Y) is the response or the criterion variable that is presumed to be caused by or influenced by the independent treatment conditions and any other independent variables. In this study the dependent variable is the students' vocabulary mastery.

NO
Variables Indicator Instrument  Internetbased Project Work Arikunto (2010:193) explains that "Tool is a space of question or exercise and other tools that are used to measure the knowledge, skills, abilities or talent of the intelligentsia that is owned by an individual or group". Ary et al (1985:189) sees a test is a set of stimuli presented to individual in order to elicit responses on the basis of which a numerical score can be assigned". In getting the data, class VIII-B was become an experimental group.
In teaching learning of all process (the teacher gave pretest, using treatment ( Internet-based project work) and gave posttest in vocabulary mastery ) to the students in two meeting.
The teacher asked the students to take the written test is given, before and after treatment. Here is a description of the research activity conducted by researchers as a teacher: 1. Pre-test The pretest was conducted on 19 th May 2016. The first, the researcher came to the class and explained what they were going to do.
After that, students were given a test in the form of a written test about the narrative text.

Treatment
The researcher chose to use Internet-based Project Work as the media for the treatment held on 20 th May 2016 and performed in several steps. The first step is students listening to the explanation of the teacher of narrative text. The second step is teacher divides the students into several groups. The third step is students are asked to search for text on a narrative text on the internet. The last step is the teacher tells students presented alternately corresponding group number.

Post-test
Post-test conducted after the treatment. The researcher asked the same written test during the pre-test, it's just a matter of a given encrypted. Posttest is performed to determine whether there are differences in scores after given the treatment. The treatment was held on 20 th May 2016.
In this research, the researchers used validity and reliability test to determine valid or invalid questions used: 1. Validity test Brown (2001: 388)  The result of r xy above is then consulted to r-table by the level of significance (α) 5%. If r xy is higher than r-  Similar with validity interpretation, the result of r ii above is also consulted to r-table by the level of significance (α) 5%. If r ii is higher than r- According to Ary (2006:195)    percentage (54.84% to be 22.58% ). C grade has decreased (29.04% to be 0%). D and E grade has also decreased (0% to be 0% and 0% to be 0%). In conclusion, it shows that after using Internet-based Project Work as media to teach vocabulary had increased than before using Internet-based Project Work as media.
The analysis of this study is made from the students' score of test. As explained in previous that the instrument used in this study is vocabulary test, including pre-test and post-test. The analysis is made to find out there is any difference in students' score before and after taught using Internet-based Project Work. It is also to find out the effect of Internet-based Project Work in building up the students' vocabulary mastery and to show Internet-based Project Work can give possitive effect in increasing the students' vocabulary mastery.
In the below is commentary about validity and reliability test has been calculated by the researchers. These are some step to validity test : Example of validity tests item no 1 by using product moment correlation:  So, for the test item no 1 the validity coefficient score is 0.42.
Scores from other test items that were calculated by using product moment correlation could get the score of validity, in table 4.7 described the result of validity coefficient.
After calculating by using product moment correlation (r count ), the scores counted by using formula (t count ) as follows: Example of the calculation for t count of number 1. After calculating the reliability of the entire test item, the score of reliability is 0, 71. However, based on the criterion of reliability item (see table 3.4) the reliability score of 0, 600 until 0, 800 is categorized in good reliable. So, it can be concluded that the entire test items are good reliable.
The result of data analysis is from students' score of pre-test and posttest as in the following table.

Hypothesis Testing
From the data analysis it could be identify that: 1. When the value of T-score > T-table in d.f= 30 with the significant level 0,05, the alternative hyphotesis (Ha) is accepted and the Null Hyphotesis (Ho) is rejected. It means that there is significant different score of vocabulary mastery to the eighth grade students before and after being taught using Internet-based Project Work.
2. When the value of T-score > T-table in d.f= 30 with the significant level 0,05, the Null Hyphotesis (Ho) is accepted and the alternative hyphotesis (Ha) is rejected. It means that there is no significant different score of vocabulary mastery to the eighth grade students before and after being taught using Internet-based Project Work as media.
The mean of total vocabulary test score of 31 students before being taught by using Internet-based Project Work is (72.51). After getting treatment, the mean score of students' vocabulary is (83.16). It means that the students' score is improved.
Based on the statistical calculation using t-test, the researcher gives interpretation to t count. First, she considered the d.f. with the d.f (31-2=29).
She checked to the score of "t " at the significance level of 0,05. In fact, with the d.f of (29) and the critical value at 0,05 significance t table was (2.045).
By comparing the "t" that she got in calculation t count = (11.641) and the value of "t" on the t table = t 0.05 = (2,045). It is known that t count is bigger that t table = 11.641> 2.045 Because the t count is bigger than t table the null hyphotesis (Ho) is rejected and the alternative hyphotesis (Ha) is accepted. It meant that there is significance different score of the students vocabulary mastery of the eighth grade students of SMPN 1 DURENAN before and after being taught by using Internet-based Project Work as media.
The objective of this study is to know if there was an effect of using Based on the explanation above the teacher must not only focus on presenting materials for the students but the most important one must be concidered that is how to presents the materials. In this research, the researchers using Internet-based project work as a way in teaching vocabulary. In this media the students study vocabulary independently by searching on the internet, it makes them more responsible in their study.
This media is done to make the use of Internet-based Project Work in teaching learning proccess as usual as using books so the students be aware with technology.

Conclusion
Result of research finding, the researcher concludes that as follow: 1. The student's achievement before taught by using Internet-based Project Work is good because the mean of the total score of 31 students is (72.51).

The student's achievement after taught by Internet-based Project
Work is very good because the mean of the total score of 31 students is (83.16).
3. Based on the statistical using analysis Ttest with the significant level 0,05 and the d.f= 29 showsthe value of table "t" = (2.045). While, t count is (11.319). Because the t count ishigher than t table the alternative hypothesis (Ha) that states there is significant difference score of the students vocabulary achievement by using Internet-based Project Work is accepted, while the null hypothesis (H o ) that states there is no significant difference score of the students' vocabulary achievement by using Internetbased Project Work is rejected. So, there is any significant difference score of the students vocabulary achievement before and after taught by using Internet-based Project Work.
From the result above implies that the Internet-based project work technique as media is effective used in teaching vocabulary to the eight grade students of SMPN 1 DURENAN.
Some suggestion are addressed to the students, teachers and future writer, as follows: 1. For the Students : By Internet-based Project Work as media, the students improve their achievement in vocabulary. The students are suggested to follow up the vocabulary by using it in their study. The students would be active and independent in classroom because Internetbased Project Work helps the students to be active in learning English. It is hoped that the students can increase and improve their ability. The students not only understand the word from the books but also the students uses the technology in learning. So, the use of technology in teaching learning becomes as common as use the books.
2. For the Teacher : In order to succeed in teaching English, Internetbased Project Work should be used for teaching learning English, especially vocabulary. The teacher can be more creative in applying that technique to the students and use it in teaching vocabulary so that the students will be spirit and interested in learning English.
3. Finally, For the Next Researcher : this research is not perfect yet, it is suggested for the future researcher to conduct further research on the similar area by improving the methodology or use it as reference to conduct a futher research related to Internet-based Project Work in different area of teaching. This study is very important because it will give some knowledge to the researcher and to know the benefits of using Internet-based Project Work in teaching English
