THE INFLUENCE OF THE HELLO ENGLISH APPLICATION TOWARDS STUDENTS ’ LEARNING ACHIEVEMENT IN VOCABULARY MASTERY

The objective of this research was to determine the impact of the Hello English application on students' vocabulary acquisition. This study adopted a quasi-experimental design and quantitative research methodology. Data were obtained from 30 eighth-grade students, 15 of whom were in the experimental class and 15 of whom were in the control class. The instrument for data collection was vocabulary tests that were intended to determine if the Hello English program had an effect on students' vocabulary knowledge. The findings of the data analysis indicate that the experimental class's mean score on the pre-test was only 34 but climbed to 57.3 on the post-test. In contrast, the mean pre-test score for the control group was 43, whereas the post-test score was just 39.6. As a result, the class adopting Hello English as the treatment saw a considerable improvement.


INTRODUCTION
We must have a strong vocabulary to articulate our thoughts and comprehend what others are saying (Alqahtani 2015).Therefore, vocabulary is the cornerstone for assisting the language acquisition of international students.On the other hand, students learning a foreign language confront some major challenges, one of which is the difficulty of growing their vocabulary (Zalmansyah 2013).In addition, there are still many educators who are unaware of the significance of vocabulary development for young language learners.Priyono in Ginting (2019) said that pupils' restricted vocabulary has been their greatest obstacle in the EFL environment while learning English.This issue may be related to how instructors and students see vocabulary teaching and learning and how vocabulary is taught and learned in ELT.In addition, pupils had difficulty comprehending the lecture and lacked enthusiasm to learn English owing to a lack of vocabulary competence.Southerland said that junior high school instructors must capture the interest of their pupils since adolescents at this age are quickly bored (Southerland 2011).
In addition, the online learning method led to declining student success.Learning achievement is the degree of a student's success in learning the subject matter in school, as measured by scores on topic-specific assessments (Tari 2021).In this moment and context, mobile learning is essential for instruction.In addition, the pupils represent the Z generation.The Z generation was born after the advent of technology.This situation makes this generation's society technologically advanced, adaptable, more intelligent, and tolerant (Rastati 2018).As an alternative to teaching and learning English, several programs are available, notably for teaching vocabulary, such as Hallo English.It was launched in October 2014 by Culture Alley.It has 475 interactive lessons, games, live classes with a professional teacher, trending news and articles, role-play (conversation), tip of the day, word of the day, and a helpline (ask teachers).This app is available on iOS, Windows, the web, and Android.It makes it easy to use for everyone and everywhere.
Below, the writers highlight recent studies on the Hello English app.Maimanah (2020), in her research, stated that the Hello English app made it easier for students to memorize vocabulary.Besides, it helped students pronounce the vocabulary correctly and find new vocabulary creatively.The Hello English app positively impacted and motivated them to learn English.The result of the research was collected through interviews about the students' higher education perceptions.Another researcher, Fendiasari (2020), investigated the effectiveness of the Hello English app.Using a quasi-experimental design, she found that the average of the experimental class became higher after using the Hello English app.It means there is a significant difference between the application and conventional methods, and it is effective in teaching English in senior high school, particularly vocabulary.Ginting (2019) also described and supported the previous explanation that the Hello English app has significant effect on the students' vocabulary mastery.Liana, Wahyudin, and Hanoum ( 2018), in their research, they used the Hello English app to improve student's learning achievement, especially in improving listening skills.Their experiment research found that using Hello English improved the students' learning from under 50% to 82.16%.This result shows that the Hello English app could increase students' learning achievement in learning English, particularly in listening skills.The research by Puspitaloka et al. (2017) aimed to improve young learners' vocabulary using the Hello English app.The research was implemented for four weeks using the Hello English app as an Android-based educational game.Besides, the research used experimental and controlled classes.The result showed that there was a significant difference between the experimental class and the control class after the intervention was implemented.It improved students' learning competence in learning vocabulary, and the game encourages active participation during classroom activities.Using an android based educational game was one of the fun ways to teach and learn English, and it stimulated students' creativity.Furthermore, the implementation of Hello English for Teachers discovered that this was a recommended method for improving their teaching ability.
The distinction between this research and the other research in this study was made using online learning due to the COVID-19 pandemic.This study can be an alternative way for teachers and students to learn English in a fun way.The other research was conducted before online schooling.Therefore, it has a different situation.The writers intended to do further research about using Hello English to improve students' learning achievement.Thus, based on the situation, this study investigated the influence of Hello English on students '

Design
This quantitative study used a quasi-experimental method to get reliable data and compared the results to show the cause-and-effect relationship between the variables.The researcher involved two groups in this research.They are the class that did the experiment and the class that did not.Before giving either group treatment, the researcher gave each of them a pre-test.The Hello English app was then given to the experimental class to help them learn English and vocabulary.On the other hand, the Hello English program was not used in the control group.After the treatment, there was a test to see if the Hello English app had any effect.

Population and Sample
The population in this study was eighth graders.Moreover, the sample was obtained through cluster random sampling.The sample was split between two distinct groups.These are the experimental and control groups.Fifteen pupils in the experimental class received therapy by learning English using Hello English.However, the control class, which served as the experimental class's comparison group, did not give any treatment.There were 25 pupils in this class who were not given any therapy.

Research Instruments
A research instrument is necessary for the study.It is needed to obtain and collect relevant information for the research (Wilkinson and Birmingham 2003).It helped the writers do the research and get the data needed to find the result of the study.To collect the data for this study, the writers need tools to collect them.It is referred to as an instrument.The research instrument used in this study was a test.The researcher did the test twice.The first test was called the pre-test.The test intended to see the students' English level before the writers applied the treatment.
On the other hand, the control group does not receive any treatment; they are subjected to all of the tests.The second test is called the "post-test" or "final test."This test aimed to see the value after the treatment was applied.The pre-test and the post-test all contain 20 numbers of multiple-choice and 5 points for each correct answer.The students get a score of 100 if they get the correct answer for all the questions.
Furthermore, the instrument used by the author has been validated to determine whether or not the test is valid.According to Ghozali in Armin (2020), the value of the r count is compared to the value of the r table to calculate the validity test.If r count > r, a table with the significance level is displayed, and the value is less than 05, the statement in the test is invalid.Besides the validation, the test was also analyzed for reliability.A reliability test is a way to determine how reliable a test is to predict a variable or concept.A test is said to be reliable if the same person always gives the same answer to the same question.After they did a validity test, the writers did a reliability test on Microsoft Excel.
In collecting data, the writers used pre-test and post-test.The test was multiple-choice and consisted of 20 questions.The questions were selected from questions or materials in the Hello English application.Each question has five points for the correct answer.Therefore, if the students get 20 correct answers, they get 100.The pre-test and post-test questions were different yet still had the same level and composition.This technique was intended to get more valid data.In the pre-test, the test was given to both classes.The test aimed to analyze the students' English levels.Besides, it was used as a data comparison for the posttest score.After giving the pre-test, the next procedure was to continue treating the experimental class.The treatment was conducted over eight meetings.In addition, students in the experimental class learned English through the Hello English application online twice weekly.Every time the students used the Hello English application, they completed two missions from the app (for each meeting).For the next meeting, the students continued with the next mission from the Hello English application.In the post-test, both classes took a test.The questions for the post-test are different from the pre-test questions, but they still have the same context and level as the previous pre-test's questions.This post-test aimed to see whether there was a difference between the two classes and whether there was a substantial improvement in the student's learning achievement.

Data Analysis
Data analysis was a step the researcher took after collecting data to answer the problem statement and verify the hypothesis by calculating data groupings from the respondents and variables.Present the data based on the variable from all the responses (Sugiyono 2011).Besides, the technique of data analysis in this study used SPSS 22.The data was collected and then analyzed with the normality test using a paired T-test, which is the dissimilarity of two groups with a normal distribution.The researcher used Shapiro-Wilk as the formula for the normality test by using the SPSS 22 application due to the small sample size (below 50 samples).A homogeneity test was also used to look at the data.As the assumption from the independent T-test shows, there must be a homogeneity test.This homogeneity test aims to find out if all of the different data types in a population have the same variation.Even though the test result for homogeneity is not uniform, the independent test can still be done.A paired T-test is also needed to make a research decision.After the normality and homogeneity tests are done, it can be seen whether there is a significant change in the paired sample.The pre-test and post-test from each class were used to test the data.If the significant level is less than .05,then the Hello English app's use affects how well the students learn.If the significant level is more than.05,using Hello English doesn't change how well students learn.The hypothesis test was the last part of the analysis.The goal was to find out if the information strongly supported the hypothesis about the characteristics of the population.

Findings
After completing the investigation, the writers uncovered two categories of data.There were both experimental class (VIII-C) and control class (VIII-C) data (VIII-B).The pre-test and post-test of the examination yielded quantifiable results.During the first meeting, the pre-test was administered before the therapy.In contrast, the post-test was administered at the last meeting after the therapy.The outcome of the pre-test was as follows: The above graph shows how the two classes did on their pre-tests.In the experimental class, one student's grade ranged from 0 to 19 points.Four students in the experimental group and two students in the control group got between 20 and 29 points.Five students in the group and two students in the control group got a score between 30 and 39.Three students in the experimental group and five students in the control group got grades between 40 and 49.In the experimental group, only one student had a score between 50 and 59.This was not the case in the control group.Two students in the control group and one student in the experimental group got scores between 60 and 69.The results of both courses were almost the same, which shows that their vocabulary levels are similar.On the other hand, here's what happened in the post-test: Based on the post-test results, the above graph shows how the values of the two groups compare.The numbers showed that the four students in the control group with the worst scores were all in the control group (20-29).In the meantime, there was no one in the experimental class.Then, in the experimental class, there was a student with a score between 30 and 39.On the other hand, the control group had only three people.Four students in the experimental class got between 40 and 49 points.Three people did it in the control class.Also, more people with scores between 50 and 59 were in the experimental class.Five students in the experimental class and two people in the control class got scores between 60 and 69.Two students in the experimental class and one student in the control class got 70-79.The highest score on the test was between 80 and 89.Students with this score are in the experimental class, which has only one student, while the control class has no one with this score.
After describing the data findings from the tests, this study also spelled out the findings of the analysis of the collected data.The writers analyzed the data in three ways in this study.First, using normality and homogeneity tests on the preliminary data.Second, calculating the hypothesis test results.Finally, the research concluded by counting the statistical hypotheses.First, in the normality test, the data was analyzed using Saphiro-Wilk.The result of the test is as follows: Teaching English is also very suitable for these students because the learning is smartphonebased, and they are the Z generation.They were born and grew up with and love technology, so they can use this app easily.Referring to the findings and the data analysis, Hello English influenced students' learning achievement, particularly vocabulary.It can be seen from the value of the experimental class, which increased significantly after this method was applied, while the value of the controlled class did not increase significantly.

CONCLUSION
After researching and analyzing the data, it was feasible to conclude that Hello English impacted students' vocabulary mastery.As evidence, the experimental group's post-test scores increased after the treatment was given.The mean score in the experimental pre-test class is only 34; nevertheless, it rises to 57.3 on the post-test.The control group's mean pretest score was 43, and their post-test score was just 39.6.If the result of the independent sample t-test sig.(2-tailed) less than .05,then there was a substantial difference between the classes.As a result, sig (two-tailed) proved .002and was less than .05.This presented that Ha was accepted.
Refers to the above conclusion, this study is hoped to be useful and persuade readers to use attractive media to learn English.One of the media is the Hello English application.Furthermore, it is hoped that the teacher will be able to use an enjoyable method or tool in teaching English, particularly in online learning.The writers also hoped this study would serve as a resource for future researchers interested in this topic.
