This qualitative classroom action research investigates the impact of theme-based
teaching on Indonesian junior high school students' descriptive writing ability.
Recognizing students' struggles with idea expression, paragraph structure, and
vocabulary in descriptive texts, this research implemented "My Favourite Animal"
as a central theme to enhance engagement and writing proficiency. Conducted
with twenty-five students, data were gathered through classroom observations,
semi-structured interviews, and analysis of student writing products across three
meetings. Thematic analysis revealed that the theme-based approach significantly
boosted student engagement and motivation due to its personal relevance.
Collaborative activities fostered idea generation and vocabulary development.
While students showed improved confidence and understanding of descriptive text
structure, challenges in grammatical accuracy and vocabulary breadth persisted.
Students suggested incorporating more practical activities, leveraging technology,
and diversifying themes. Based on the result, theme-based teaching effectively
enhances descriptive writing skills by increasing motivation and collaboration.
However, continuous explicit instruction in grammar and vocabulary remains
crucial for optimal learning outcomes. This research offers practical insights for
engaging writing instruction at the junior high school level.
A. Conclusion
Based on the results of qualitative classroom action research conducted
on the use of theme-based teaching to improve the descriptive writing skills of
junior high school students in Indonesia, several key conclusions can be drawn
that answer the research questions:
1 Student Experience and Engagement in Writing Descriptive Texts through
Theme-Based Teaching
a. Increased Engagement and Motivation:
This research clearly shows that theme-based teaching, especially
with relevant and interesting themes such as ‘My Favourite Animal’,
significantly increases student engagement and motivation in descriptive
writing activities. Interactive activities such as animal guessing games
and the use of visual media (images and videos) in the first and second
sessions successfully captured students' attention and created a pleasant
learning atmosphere. The connection between the theme and students'
personal interests made them more enthusiastic and reduced their
anxiety in writing, as ideas could emerge more quickly and easily.
b. Facilitating Ideas and Vocabulary:
The thematic approach facilitates students in generating ideas and
enriching their vocabulary. Group discussions and peer reviews have
proven to be effective means for students to exchange vocabulary,
provide feedback, and broaden their writing perspectives. Students feel
more confident in expressing their ideas, even those inspired by popular
57

culture such as anime or mythology, indicating that personal interests
can be a strong trigger for intrinsic motivation.
c. Increased Confidence and Creativity:
Students show increased confidence and creativity in writing. They
feel a sense of ‘ownership’ over the writing process because the chosen
themes are relevant to their lives. This encourages them to express ideas
more freely and take risks in language use, as seen in the unique details
and imaginative elements in their writing.
2 Advantages and Disadvantages of Applying Theme-Based Teaching in
Writing Descriptive Texts
a. Advantages:
1) Increases Motivation and Interest in Learning: Relevant and
familiar themes significantly increase students' interest and
motivation to write, making the learning process more enjoyable
and less tedious.
2) Facilitates Idea Generation: Students find it easier to generate
ideas and develop written content because the chosen themes are
close to their experiences and knowledge.
3) Encourages Collaboration: Group activities and peer review
promote interaction among students, allowing them to help each
other in developing vocabulary and sentence structure.
4) Enhances Creativity: Students feel more free to explore creative
ideas and incorporate personal or imaginative elements into their
writing.
b. Disadvantages/Challenges:
1) Grammatical Accuracy and Vocabulary Limitations: Despite
improvements in content and vocabulary, students still face
significant challenges in grammatical accuracy (e.g., use of
articles, subject-verb agreement, and verb forms) and specific
vocabulary limitations. Errors such as ‘Cat is small animal’ are
still common.
2) Anxiety in Using English: Some students, especially those with
lower proficiency levels, still feel less confident and anxious
about making grammatical errors, which sometimes hinders their
writing process.
3) Need for Additional Support: More targeted support and practice
are needed to address grammatical difficulties and enrich
vocabulary more deeply, beyond thematic focus.
Overall, theme-based teaching has proven to be an effective approach
in increasing student engagement, motivation, and creativity in writing
descriptive texts. However, to optimise the results, more attention needs to be
paid to grammatical accuracy and explicit vocabulary enrichment.
B. Suggestions
Based on the findings and conclusions of this research, here are some
practical suggestions that education practitioners may consider and
recommendations for further research:
1 For Practitioners (Teachers)
a. Choose Relevant and Interesting Themes:
Teachers are advised to continue choosing themes that are close to
students' lives and interests (e.g., hobbies, favourite places, inspirational
figures, or interesting natural phenomena). The relevance of the theme is
key to triggering intrinsic motivation and facilitating the generation of
ideas.
Conduct an interest survey or preliminary discussion with students
to identify the topics that interest them most.Integrasikan
b. Interactive and Multimodal Activities
Utilise various visual media (images, videos, interactive
presentations) and ice-breaking activities or games relevant to the theme
to attract students' attention from the start of the lesson.
Encourage the use of technology (interactive applications, online
learning platforms) to enrich the learning experience and enable students
to learn independently.
c. Strengthen Collaboration and Peer Learning
Design more writing activities that involve pair or small group
discussions. This will provide opportunities for students to exchange
ideas,
enrich their vocabulary, and provide constructive
feedback.Berikan panduan yang jelas tentang cara memberikan dan

d. Explicit Focus on Grammar and Vocabulary
Although theme-based teaching focuses on meaning and context,
teachers need to explicitly integrate strategies that focus on form. This
can be done through:
1) Mini-lessons: Short sessions that discuss grammar points that are
often problematic (e.g., use of articles, subject-verb agreement,
tenses).
2) Targeted Feedback: Provide specific and constructive feedback on
grammar and vocabulary errors in students' writing, and give them
the opportunity to revise.
3) Thematic Vocabulary Lists: Provide a list of vocabulary relevant to
the theme, along with examples of its use in sentences, before
students begin writing.
4) Repetitive Practice: Provide additional exercises to reinforce the use
of new vocabulary and difficult grammar structures.
e. Allocate Sufficient Time for Revision
Allow students sufficient time to revise their writing after receiving
feedback, both from teachers and peers. The revision process is a
crucial part of developing writing skills.
2. For Future Researchers
a. Quantitative Research to Measure Long-Term Impact
Further research could use quantitative designs (e.g., quasi-
experimental designs with control groups) to statistically measure the
impact of theme-based teaching on long-term improvements in
students' descriptive writing abilities, including test scores and
developments in linguistic accuracy.
b. Explore Various Themes and Educational Levels
Conduct similar research with more varied themes (e.g., favourite
places, inspirational figures, historical events) and at different
educational levels (e.g., high school or university) to see if the findings
can be generalised.
c. In-depth Case Studies of Students with Different Proficiency Levels:
Focus case studies on students with different levels of English
proficiency (beginner, intermediate, advanced) to gain a deeper
understanding of how theme-based teaching affects them and which
strategies are most effective for each group.
d. The Role of Teachers in Implementing Theme-Based Teaching:
Further investigate the role and challenges faced by teachers in
designing and implementing theme-based teaching, including the
training required and effective support.
e. Development of an Integrated Learning Model:
Develop and test a learning model that integrates theme-based
teaching with an explicit focus on grammar and vocabulary, as well as
the use of technology, to create a more comprehensive approach to
teaching writing.
By implementing these suggestions, it is hoped that theme-based
teaching can be more effective in improving the descriptive writing skills of
junior high school students in Indonesia.
At the same time, it will contribute more broadly to the development
of English language teaching practices
