A INTRODUCTION

I RATIONALE FOR CHOOSING THE TOPIC

In the context of integration and globalization, English is playing anincreasingly important role in education, work, and international communication Asone of the core subjects in high school, English not only helps students improve theirlanguage skills but also opens up numerous opportunities in learning, careers, andcultural exchange However, to use English fluently, students need to possess a richvocabulary, as vocabulary is the foundation for developing language skills such aslistening, speaking, reading, and writing

In actual teaching practice, many students still face difficulties inremembering and effectively using English vocabulary Traditional learningmethods such as repeatedly copying new words, rote memorization using wordlists, and mechanical repetition often prove to be ineffective in the long run Thesemethods can easily cause boredom, reduce motivation, and lead to studentsforgetting vocabulary quickly, failing to apply it in real-life communication, andeventually developing a fear of English and losing confidence in using thelanguage

Faced with this situation, teachers need to adopt innovative teaching methods

to motivate and engage students in vocabulary learning In the era of Industry 4.0,integrating digital learning tools is a necessary and effective direction Among the

popular tools today, Quizlet stands out as a modern, user-friendly, and convenient

learning application, which is particularly suitable for high school students."

Quizlet is an online learning platform that allows teachers and students to

create, share, and practice vocabulary sets through flashcards, games, and diversequizzes With its intuitive interface, ease of use, and a variety of engaging learningmodes such as “Match”, “Gravity”, and “Learn”, Quizlet helps students remembervocabulary in a vivid, fast, and systematic way Notably, students can studyanytime, anywhere via smartphones or computers, which aligns with today’s trend

of flexible learning

With these outstanding advantages, I recognize that applying Quizlet inteaching and learning English vocabulary is a feasible and necessary direction.With the desire to help students enjoy learning new words, improve retention,reinforce their knowledge more effectively, and form active self-study habits, Iboldly chose the topic for my educational initiative:

“Using Quizlet to Teach and Learn English Vocabulary Effectively for High School Students.”

I strongly believe that implementing this initiative in real teaching practicewill bring about positive changes in students’ vocabulary learning At the sametime, the topic contributes to promoting digital transformation in education,enhancing students’ proactiveness and engagement, thereby improving the quality

of teaching and learning English at school

II OBJECTIVES OF THE STUDY

Vocabulary learning plays a crucial role in acquiring and using a language InEnglish, vocabulary serves as the foundation for developing listening, speaking,reading, and writing skills, while also acting as a bridge that enables students toapply language knowledge in real-life contexts

However, in actual high school classrooms, vocabulary learning still encountersmany challenges Students often resort to rote memorization, lack contextualunderstanding, and have limited opportunities to practice in interactiveenvironments—resulting in low retention rates and restricted application

Amid the ongoing digital transformation in education, integratinginformation technology into teaching is not only a trend but also a necessaryresponse to the demands of modern education For today’s students—digitalnatives adept at using smart devices and online platforms—reforming teachingmethods to integrate technology is essential for enhancing educationaleffectiveness, particularly in vocabulary instruction.

Based on this context, the study titled:

“Using Quizlet to Teach and Learn English Vocabulary Effectively for High School Students”

is developed with the following main objectives:

1 To survey and assess the current situation of vocabulary learning among high school students.

This objective aims to investigate the current practices in English vocabularylearning at the high school level—including commonly used methods, theireffectiveness, student engagement, and existing difficulties By collectingauthentic data from both students and teachers, the study provides acomprehensive overview that underscores the need for innovative, technology-supported vocabulary instruction

2 To explore and evaluate the effectiveness of applying technology specifically the Quizlet tool in vocabulary teaching and learning.

Quizlet is an online platform designed to support learning through flashcardsand interactive games This study seeks to explore the tool’s features and potential

in supporting vocabulary acquisition It further aims to evaluate the tool’seffectiveness when implemented in high school settings, focusing on studentengagement, independent learning, and measurable outcomes

3 To develop a suitable and practical process for applying Quizlet, tailored to high school students.

A central goal of this research is to design and pilot a structured teachingprocess that effectively integrates Quizlet into vocabulary instruction Thisprocess will not only leverage technology but also align with the psychologicaland cognitive characteristics of high school learners It will aim to foster self-directed learning, teamwork, and a proactive learning mindset

4 To contribute to the innovation of English teaching methods in line with developing learner competencies.

The initiative aims to go beyond vocabulary acquisition by supporting theholistic development of student competencies aligned with the new GeneralEducation Program The use of Quizlet encourages students to practicetechnological skills, critical thinking, and memory retention, while alsosupporting teachers in transitioning from traditional teaching to modern, learner-centered approaches

5 To enhance the quality of English language teaching and advance digital transformation in education.

Ultimately, the study aspires to contribute to the improvement of Englishteaching quality in schools The use of Quizlet is proposed not as a temporarysolution but as a sustainable, efficient tool that benefits both teachers and learners Italso aligns with national goals for educational digital transformation by promotingthe creative integration of technology in everyday teaching practices

This research is limited to the teaching and learning of English vocabulary

using the Quizlet application at the high school level It does not extend into the depth teaching of other language skills such as grammar, reading comprehension,

in-or writing Instead, the study emphasizes the enrichment of students’ vocabulary knowledge, enhanced retention, and practical usage of vocabulary

through digital tools

* Time Frame:

The study is conducted and piloted during the 2024–2025 academic year, and

includes several phases:

IV RESEARCH METHODS

To achieve the research objective of evaluating the effectiveness of using

Quizlet in teaching and learning English vocabulary among high school students,

a combination of flexible and context-appropriate research methods wasemployed These methods are designed not only to gather survey data but also toassess the practical feasibility and impact of integrating this tool into actualclassroom instruction.

1 Survey Method

The survey method serves as the primary research tool in this study, aimed

at collecting foundational information regarding students’ habits and challenges

in learning English vocabulary prior to the implementation of Quizlet

Data was collected through a structured questionnaire, which included

questions related to:

- The current methods used for vocabulary learning

- Students’ interest and motivation levels

- Memory retention ability

- Difficulties encountered in vocabulary acquisition

The goal of this survey is to identify the key factors influencing vocabulary learning outcomes Specifically, it seeks to explore students’ study

behaviors and pinpoint common obstacles in acquiring English vocabulary The

results obtained from the questionnaire will form a critical baseline for

comparison, enabling an objective assessment of the changes and improvementsobserved after Quizlet is introduced into the teaching process

SURVEY ON THE CURRENT SITUATION OF ENGLISH VOCABULARY LEARNING BEFORE USING QUIZLET (See the survey

form 1 attached in the appendix.)

**EVALUATION CONCLUSION AFTER THE SURVEY

1 1 Students' vocabulary learning methods.

Before using Quizlet, most students learned vocabulary through traditionalmethods such as:

• Writing words and their meanings in notebooks and memorizing them

• Translating English words into Vietnamese

• Doing exercises in textbooks or vocabulary quizzes

• Reviewing through class exercises, mostly theoretical exercises withoutreal-life interaction

Learning through these methods often makes students feel bored and theytend to forget the vocabulary after learning The main difficulties they faceinclude:

• Lack of motivation and encouragement during the learning process

• Lack of effective methods for long-term vocabulary retention

• No opportunity to practice vocabulary in real communication contexts

1 2.Difficulties in learning vocabulary.

Through the survey, I identified common difficulties students face when learningEnglish vocabulary, including:

• Difficulty in remembering vocabulary for the long term Students often forgetwords quickly due to the lack of an effective review method and insufficientrepetition

• Vocabulary is not connected to real-life situations, making students not see thenecessity and interest in learning vocabulary

• Low participation: Students feel that learning vocabulary is a boring task,lacking interaction, which reduces their motivation to learn

• Lack of time for review: Due to a heavy study schedule, students do not have

enough time to review vocabulary or practice learned words.

• Inefficient search for learning materials: Students sometimes face difficulties inselecting suitable learning tools or do not know how to use them properly

1.3 Students’ interest in learning English vocabulary.

Students reported that their interest in learning English vocabulary is low Only afew students said they enjoy learning vocabulary, while the rest often feeldiscouraged when they have to memorize words without understanding their real-life context They expressed a desire for a learning method that is both effectiveand fun, one that could increase engagement and motivation in learning

1.4 Desired improvements in vocabulary learning.

Students also shared their wishes for improving their vocabulary learning,including:

• Making the learning process more dynamic and interesting, rather than dryand monotonous

• Providing various learning methods to allow students to choose the onethat fits them best

• Allowing students to learn vocabulary anytime and anywhere, withoutbeing limited by time or place

• Having smart review tools to track learning progress and systematicallyrevise vocabulary that has been learned

* Conclusion on Information Gathering.

Based on the information gathered from the survey, I found that students arecurrently facing many difficulties and challenges in learning English vocabulary,particularly the lack of interest and effective learning methods This shows thatusing technology and modern learning tools, such as Quizlet, could address theseweaknesses and create a more dynamic, enjoyable, and effective learningenvironment

The results from this survey will serve as a foundation for testing andevaluating the effectiveness of Quizlet in improving English vocabulary learningfor students This will also help increase students' motivation and long-termmemory retention in the subject

The survey was distributed to 100 students at Mường Lát High School(including students from different classes) and analyzed both qualitatively andquantitatively The survey questions will help identify specific factors thatstudents face when learning vocabulary, and from there, propose solutions forimprovement

2 Classroom Observation Method

2.4 Analysis of Results:

After collecting data from observations and surveys, the results will beanalyzed both qualitatively and quantitatively to draw conclusions about thechanges in students' learning attitudes

- Qualitative Analysis: Analyze the feedback from students about their

perceptions of vocabulary learning through Quizlet Specifically, do students feelthat learning vocabulary has become more interesting? Do they take moreinitiative in learning and self-study outside of class? Do they find it easier to applythe vocabulary in writing and speaking tasks after using Quizlet?

- Quantitative Analysis: Data will be compiled from test results, the

number of students participating in learning activities, and the percentage of

students who remember vocabulary after using Quizlet compared to traditionallearning methods The results will be analyzed in percentages to determine thedegree of change and the effectiveness of the Quizlet method.

2.5 Comparison of Results Between Two Methods:

Traditional Method: In traditional vocabulary learning (writing down andmemorizing), students often find it boring, difficult to remember long-term, andchallenging to apply vocabulary in real-life situations Survey and observation resultsshow low participation, little interest, and slow progress in learning

Quizlet Method: When using Quizlet, students are more active and engage

in vocabulary learning through games and online quizzes, which makes themmore interested They can review vocabulary anytime, anywhere, and their long-term retention of vocabulary improves significantly Students' attitudes towardslearning are generally more positive, with higher participation rates and betterapplication of vocabulary in real contexts

2.6 Conclusions from Observations:

The results of the observations will show that using Quizlet for learningEnglish vocabulary not only makes students more interested in learning but alsosignificantly improves their ability to retain and apply vocabulary effectively.This will lead to a positive change in students' attitudes, especially for those whofelt that traditional methods were not suitable for their learning needs

3 Pedagogical Experiment Method

To evaluate the effectiveness of Quizlet, I will conduct a pedagogicalexperiment with two groups of students:

3.1 Experimental Group : This group of students will use Quizlet to learn

English vocabulary Quizlet will be applied over a period of 6–8 weeks, followingspecific lessons Throughout the experiment, students will be guided on how touse Quizlet to create and study flashcards, and participate in vocabulary reviewgames

3.2 Control Group : This group of students will learn vocabulary using the

traditional method, primarily memorizing words and their meanings throughwriting and exercises from the textbook

After the experimental period, both groups will participate in vocabulary tests toassess their learning outcomes The results, including scores, vocabularyretention, and the ability to use vocabulary in both groups, will be compared toevaluate the effectiveness of the Quizlet method

4 Data Analysis Method:

Data collected from surveys and learning outcome tests will be analyzed andprocessed using statistical methods Specifically:

4.1 Quantitative Data: Statistical calculations will be used to determine thepercentage of students who remember vocabulary, compare pre- and post-testscores after using Quizlet, and analyze changes in their learning engagement

4.2 Qualitative Data: The responses from students in the surveys regardingtheir learning attitudes and perceptions of using Quizlet will be analyzed Theseresponses will provide detailed insights into the differences in learning methodsand the improvements seen in students

The data analysis method will provide clear conclusions regarding theeffectiveness and feasibility of using Quizlet in vocabulary teaching and learning

5 In-depth Interview Method:

To supplement the necessary information for the evaluation, I will conductin-depth interviews with teachers and students regarding their perceptions ofvocabulary learning with Quizlet The interviews will help clarify issues such as:

- The ease of use and effectiveness of Quizlet for students

- Changes in students' learning attitudes when using Quizlet

- Challenges encountered when implementing Quizlet in the classroom.Through the interview method, I will gain perspectives from both teachers andstudents, helping to provide recommendations and improvements in using Quizlet

* EXPECTED RESULTS:

Based on the proposed research methodology, I expect the following resultsafter implementing Quizlet in teaching and learning English vocabulary for highschool students:

1* Enhancement of Vocabulary Retention Effectiveness

Before using Quizlet, students faced many difficulties in memorizing andapplying English vocabulary, mainly due to the dry and boring traditional learningmethods However, after learning with Quizlet, students will have the opportunity touse flashcards, engage in review games, and practice vocabulary through fun andaccessible exercises, which will help improve long-term retention It is expected thatthe vocabulary retention rate will improve by 20-30% compared to traditionallearning methods, especially among weaker students

2* Improved Interest and Motivation in Learning

High school students often find vocabulary learning to be dull anduninteresting, which leads to a lack of motivation However, by using Quizlet,students will engage in dynamic learning activities such as games, quizzes, andflashcards, making vocabulary learning more enjoyable I predict that the level ofinterest and motivation among students will increase significantly, with around70% of students in the experimental group expressing enthusiasm and activelyparticipating in vocabulary learning activities

3* Enhanced Ability to Use Vocabulary in Context

By providing dynamic vocabulary learning tools that are easy to apply inreal-life situations, Quizlet will help students not only memorize vocabulary butalso use it in practical contexts It is expected that after using Quizlet, students will

be more confident in using vocabulary in writing, speaking, and dailycommunication I predict that around 60-70% of students in the experimentalgroup will improve their ability to use vocabulary in communication and exams

4* Reducing the Gap Between Student Groups

One of the goals of this research is to minimize the gap in vocabulary learningoutcomes between different groups of students Weaker students will be bettersupported by Quizlet’s repetition features and individualized learning progress.Through Quizlet, they can review vocabulary at their own pace, leading to improvedacademic results It is expected that weaker students will show significantimprovement in vocabulary retention, reducing the gap with their stronger peers

5* Enhancing Students’ Self-Learning Ability

Using Quizlet also helps students develop self-learning skills, which arecrucial in language acquisition Students can use Quizlet anytime and anywhere

on their phones or tablets, creating a habit of proactive and continuous learning It

is predicted that after implementing Quizlet, around 50% of students willexperience a positive change in their vocabulary learning habits, shifting frompassive, scheduled learning to regular, self-directed review.

6* Enhancing the Use of Technology in Learning

The integration of technology in education not only helps students accessmodern learning methods but also familiarizes them with online learning tools,enhancing their technological skills for academic purposes Quizlet is animportant stepping stone that enables students to develop essential technologicalskills for the 21st century

SUMMARY

The anticipated results of using Quizlet in teaching and learning Englishvocabulary will bring significant benefits to high school students, especially inimproving learning effectiveness, boosting interest in vocabulary learning, andenhancing the ability to use vocabulary in real-life situations These results willform a solid foundation for continuing to expand this learning model to otherschools in the province and nationwide

V INNOVATIVE ASPECTS OF THE PRACTICAL EXPERIENCE INITIATIVE

1 High Interactivity and Active Learning Methodology.

A new and outstanding feature of this initiative is the integration ofvocabulary teaching and learning through Quizlet, where both teachers andstudents can independently design lesson content according to the curriculum.This is something that many other AI applications have not yet fully addressed.Quizlet offers numerous interactive activities such as flashcard games, quizzes,and tests, enabling teachers and students not only to teach and learn passively butalso to engage actively in the teaching and learning process These activitiesencourage more active participation from both teachers and students, creating anenjoyable and accessible learning environment

2.Diverse and Flexible Technology Application

Quizlet is not just a simple vocabulary learning tool; it also integrates variousfeatures that allow teachers and students to create vocabulary lessons in differentforms, such as flashcards, quizzes, games, and challenges, to test vocabularyretention and understanding This sets it apart from many other AI applications.Other apps often focus primarily on theoretical lessons or lack sufficientinteractivity Quizlet offers flexibility, allowing students to learn anytime,anywhere, using mobile phones, tablets, or desktop computers Teachers candesign engaging, dynamic, and easy-to-understand vocabulary lessons that alignwith the curriculum at all levels No other AI application in the system can offersuch comprehensive support for all types of learners

3 Personalized Learning and Customization According to Students’ Needs

Quizlet allows students to create their own flashcards and vocabularylessons, enabling them to customize their learning methods according to their abilityand pace This creates a significant difference compared to many other AIapplications, where learning may be restricted by the pre-existing curriculum andcannot fully meet the individual needs of each student Quizlet is an open learningplatform that allows students to learn in their own unique and flexible way

4 Detailed Progress Tracking Feature

A standout feature of Quizlet is its ability to track and assess student progressthrough pre-designed quizzes and games The learning results are saved, and thesystem provides detailed statistics, helping students and teachers know what has beenlearned and reviewed, so they can adjust learning methods for better effectiveness.Other AI applications lack this feature or only provide a general evaluation, withoutdelving into the specifics of individual student progress.

5 Spaced Repetition Learning Method

Quizlet uses the spaced repetition method to help students retain vocabularylong-term This is a key factor that prevents students from quickly learning andforgetting, instead helping knowledge be reinforced and stored for the long term.Other AI applications may lack this method or, if present, do not optimize thescientific process of spaced repetition effectively

6 Social Learning and Community Connection

Quizlet creates a large learning community where students can share theirflashcards with friends or other learners around the world This promotescollaboration and connection in learning, allowing students to learn from oneanother and explore different ways of learning This is a strength compared toother AI applications, where students may learn independently without aconnection to a large learning community

7 Learning Through Real-World Context and Life Application

Unlike AI applications that teach vocabulary through simple memorization,Quizlet allows students to learn vocabulary through real-life situations The vocabularylearned is not only theoretical but can also be applied in practical communicationsituations, helping students use the vocabulary immediately in writing, speaking, oreveryday conversation This increases the practicality of the learning process, somethingthat other AI applications have not achieved effectively

8 No Need for Extensive Technical Knowledge

A prominent advantage of Quizlet is that students do not need extensive technicalknowledge to use it Quizlet has a simple, user-friendly interface, and is accessible

to students of all ages and technical levels This sets it apart from more complex

AI applications, which sometimes require students to have a certain level oftechnical knowledge in order to use them effectively

**Conclusion

The key innovations of this teaching experience (SKKN) when applying

Quizlet, compared to other AI applications, lie in its interactivity, flexibility, and high level of personalized learning Quizlet excels because it not only helps students learn vocabulary actively but also provides effective, accessible learning tools that cater to each student’s individual learning needs The

combination of modern learning methods and the community aspect within

Quizlet is a key strength, making this application an exceptional tool for learning

English vocabulary

Quizlet does not have the feature to automatically generate textbook content from the original text However, teachers and students can manually create flashcards or vocabulary lessons based on textbook content.

**NOTE

Quizlet does not automatically recognize and generate content from textbooks; instead, teachers and students need to manually input data or use pre-made flashcard sets for studying However, with this flexible feature,

teachers and students can easily create lessons from textbooks according to their learning needs.

B CONTENT OF THE INNOVATIVE EXPERIENCE INITIATIVE

I THEORETICAL BASIS OF THE INNOVATIVE EXPERIENCE INITIATIVE

Vocabulary plays a key role in shaping and developing learners' languageskills Effective teaching and learning of English vocabulary not only helpsstudents improve their four skills—listening, speaking, reading, and writing—butalso contributes to developing logical thinking, critical thinking abilities, andexpanding cultural knowledge However, in practice, teaching English vocabulary

in high schools today still faces many difficulties and limitations

The traditional method—note-taking, memorization, and doing exercises—

is still widely used but fails to generate interest, lacks interaction, and has littlepractical application Students frequently fall into a "learn and forget" cycle,where they cannot remember spelling, mispronounce words, or fail to use words

in specific contexts Many even view learning vocabulary as a burden, whichleads to passive learning attitudes and poor learning outcomes

A survey conducted in three classes from grades 10, 11, and 12 at a highschool in Mường Lát, Thanh Hóa province, found that: • Only 22% of studentsfeel excited about learning vocabulary • 88% of students find learning vocabularydifficult and easy to forget • Results from a vocabulary test at the beginning of thefirst semester showed that 85% of students scored below average, • and only 15%achieved a good or excellent score

This situation highlights the urgent need to innovate vocabulary teachingmethods, applying modern supporting tools to enhance teaching and learningquality, while aligning with the psychological development of students and thetrend of digital transformation in education

In this context, educational technology plays a crucial role in making positivechanges in foreign language learning Many language learning apps and freelanguage learning websites have been developed After years of teaching,researching, and using various software and websites to support language teachingand learning, I have drawn some conclusions about their strengths andweaknesses Based on this experience, I have identified the most effective AIsoftware for language learning For example, here are some apps I have used:

**Duolingo

* Weaknesses:

- Lack of depth: It doesn't offer in-depth lessons on grammar or advanced

conversations

- Excessive repetition: Some lessons can become repetitive, which might

lead to boredom after prolonged use

**Quizlet.

* Weaknesses:

- Limited scope: Primarily supports vocabulary learning and lacks features

to develop skills in listening, speaking, or writing

- Lack of detailed guidance: New users may struggle with creating their

own content without guidance from teachers

**Memrise

* Weaknesses:

- Limited grammar content: Focuses primarily on vocabulary and

phrases, lacking detailed grammar and conversation lessons

- Requires supplementary resources: Sometimes, the content may not be

updated regularly, requiring students to use additional learning resources

**Babbel

* Weaknesses:

Cost: Babbel is primarily a paid application, which could be a barrier for

students and families with limited budgets

Less gamified: The interface and learning approach are somewhat

traditional compared to other apps, which may not be as engaging for teenagers

**HelloTalk.

* Weaknesses:

- Requires autonomy and responsibility: Students need strong

communication skills and the ability to navigate appropriate interactions withnative speakers

- Online safety concerns: Close supervision is needed to ensure students are

not exposed to inappropriate content, especially for high school students

- Lacks structured learning content: The app is more about free exchange

and lacks a formal curriculum like other apps

***Summary:

- Duolingo and Quizlet are considered the top choices for high schoolteachers and students due to their ease of use, gamification, and suitability for

quick review and vocabulary memorization However, Quizlet stands out by

allowing both teachers and students to design lesson content that aligns closelywith their school curriculum, providing flexibility in learning

- Memrise offers a dynamic learning method through images and videos,making it a great supplement for expanding vocabulary

- Babbel is ideal for students looking for an in-depth language learningexperience, but its cost and traditional learning style may need consideration

- HelloTalk is useful for practicing communication but requires carefulmonitoring and guidance to ensure safety and appropriate interaction

Each app has its strengths and weaknesses, and students can combine them todevelop a balanced set of skills in listening, speaking, reading, and writing

II THE STATUS OF THE ISSUE BEFORE APPLYING THE INNOVATIVE EXPERIENCE.

During the process of teaching English at high school, I noticed thatvocabulary learning remains one of the biggest challenges for most students.Although vocabulary is an essential foundation for developing all four languageskills—listening, speaking, reading, and writing—students often face difficulties

in remembering, pronouncing, and using words in the correct context

The current status of vocabulary teaching and learning at my school beforeapplying the innovative experience is evident in the following aspects:

1.Monotonous Teaching Methods with Limited Interaction.

Teachers primarily used traditional methods: introducing new vocabulary,explaining meanings, and asking students to take notes and memorize There werefew creative application activities and a lack of visual tools to support learning,leading students to quickly lose interest and resort to passive learning, lacking realmotivation

2.Students Encounter Difficulties in Remembering and Using Vocabulary.

- A survey conducted with 105 students from grades 10 and 11 showed thefollowing results:

- 72% of students said that vocabulary learning is hard to remember and isquickly forgotten

- 65% of students could not use the learned words in writing or speaking

- 78% of students felt unconfident when pronouncing new words Manystudents only memorized the Vietnamese meanings without knowing the correctpronunciation, how to use the words in sentences, or the scope of meanings indifferent contexts

3.Low Academic Results.

In the periodic vocabulary test at the beginning of the school year, thestatistical data showed:

- 65% of students scored below average (below 5 points)

- 25% of students scored average (5.0 – 6.5)

- Only 10% of students scored good or excellent (above 7.0) This reflects thelimitations of the old method of memorization without deep understanding orapplication

4.Lack of Modern Learning Tools.

Although students today frequently use smartphones, they do not know how

to utilize technology effectively for their studies Vocabulary learning still relies

on textbooks, handwritten notes, and lacks modern, flexible, and digital learningapplications that match current trends in the digital age

5 Lack of Interest Among Students, with Vocabulary Learning Viewed

as a Chore

Many students shared that they learn vocabulary only for exams, notrealizing its practical importance for communication Since they do not see thereal-world applications, they forget the words after exams, creating a cycle of

"learn – forget – relearn," which is exhausting and ineffective

The above situation clearly shows the need for a reform in teaching andlearning English vocabulary at schools In this context, the application of

information technology, specifically using online learning platforms like Quizlet, is an appropriate approach that aligns with students' psychological needs and learning habits in the digital age The initiative "Using Quizlet to Teach and Learn English Vocabulary Effectively" is an innovative method that makes teaching and learning English vocabulary more effective, engaging, and suited to the current student mindset.
