Structured Opinion & Debate in English

Designing a Structured Debate Unit for Japanese Junior High Students 

Moving students from personal opinion to structured, supported argument 

Context
This unit was designed for Japanese junior high school students studying English as a required subject in Tokyo. It was based on a modified Eiken-style question and focused on helping students move beyond simple opinion statements.

Over several lessons, students moved from idea generation to short written arguments, and then into small-group debates. The goal was not just to get them speaking, but to help them organize their thinking and support what they were saying.

Instructional Challenge

Most of my students could give a basic opinion in English, but it usually stopped at one sentence. Everything defaulted to “I like,” and they often struggled to say anything beyond that.

When asked to explain why, many students either repeated themselves or fell back into silence. Even when they had ideas, they lacked a structure to organize them. I also noticed that familiar topics led to predictable answers. Students stayed safe, and the conversation didn’t go very far.

Design Approach

This unit was designed to shift students from personal preference to structured argumentation by introducing clear constraints and scaffolds.

A key design decision was modifying a traditional Eiken-style prompt into a more demanding but restricted question:

Which do you think is better for people, libraries or bookstores?

This question had several effects:

• Removed reliance on personal experience alone

• Encouraged consideration of social value

• Limited variables to increase depth of reasoning

• Required justification rather than preference

Instructional Progression

The unit moved deliberately from supported idea development toward increasingly independent language production, progressing from controlled written organization to structured oral argument in small-group discussion.

The design emphasized organization and clarity of thought over linguistic complexity.

Key Design Decisions

Constrained Prompt

Limiting the topic helped students focus on reasoning rather than searching for ideas.

The question shifted students away from personal preference and toward explaining broader value. Because the topic was constrained, students spent less time trying to invent ideas and more time developing them.

Writing Before Speaking

The sequence intentionally moved from writing to speaking.

Once students had something structured on paper, they were much more willing to speak. Instead of trying to think and speak at the same time, they could build their ideas step by step first.

Sentence Frames as Scaffolds

Instead of getting bogged down in complex grammar, the focus remained on helping students organize and extend their thinking clearly.

By using sentence frames such as “In my opinion…”, I provided a safety net for learners. This allowed even lower-confidence students to produce writing that was clear and logically organized.

Structured Progression

The unit moved gradually from:

• Individual idea generation

• Organized writing

• Structured speaking practice

• Small-group debate

This progression reduced hesitation and gave students increasing confidence at each stage.

Language Focus: Structuring Opinion and Argument

Core Structure

• Opinion: State a clear position. (I think libraries are better.)

• Reason: Give the "Why." (Because they are free.)

• Example: Provide a real-life detail. (I can borrow five books for 0 yen.)

• Opinion: Restate the point to finish strong. (So, I think libraries are great!)

Learning Goals

By the end of the unit, students were able to: 

• State an opinion and support it with at least one reason

• Expand ideas into multiple sentences

• Organize a short written argument

• Use their written ideas as a base for speaking

• Participate in small-group debates

Instructional Sequence

• Introduce the topic and clarify the question

• Introduce key vocabulary and expressions

• Brainstorm possible opinions and reasons individually and as a group

• Organize ideas using a structured worksheet

• Write a short opinion essay

• Practice speaking using sentence frames

• Move into small-group debates

The sequence moved from writing to speaking on purpose. Once students had something structured on paper, they were much more willing to speak. 

Learner Experience

1. Moving Beyond “I Like”

At the start, I asked students to explain their answers, and most responses stopped quickly. Once we shifted the question to “better for people,” they had to think differently. It wasn’t about preference anymore, which slowed them down in a productive way. 

2. Building Something to Say

The worksheet gave them a place to organize their thoughts. Instead of trying to think and speak at the same time, they could build their ideas step by step. This made a noticeable difference, especially for students who usually struggled to get started.

3. Using Writing to Support Speaking

Once their ideas were written out, speaking became easier. They weren’t memorizing sentences, but they had a structure in mind. That reduced hesitation and made their responses more consistent.

4. Small-Group Discussion

In groups, students were able to go a bit further than usual. Instead of one short answer, they could give a reason and sometimes an example. The conversations were still simple, but they lasted longer and felt more purposeful.

Assessment Strategy

Assessment was based on what students could produce over time, not a single test.

Written Work

Students wrote a short structured argument.

Focus:

• Clarity of ideas

• Organization

• Use of reasons and examples

Speaking Practice

Focus: 

• Ability to expand beyond one sentence

• Willingness to participate

Group Debate

Focus:

• Clarity of communication

• Ability to stay engaged in the discussion

Outcomes & Observations

The biggest change was in how students extended their ideas. Instead of stopping after one sentence, many were able to add a reason, and an example.

The constrained topic supported this shift. Because it was a bit limited, students didn’t spend as much time searching for ideas. They focused more on explaining what they had already decided.

Using writing before speaking also made a clear difference. Students came into debates with something prepared, which reduced hesitation and increased participation, especially for quieter students.

In some groups, discussions became highly active, with students strongly defending their positions and responding directly to opposing viewpoints. These exchanges moved beyond prepared responses and reflected a shift toward more spontaneous and engaged use of language. 

What This Project Demonstrates About My Design Approach

This project reflects how I approach instructional design within real classroom environments:

• Using structure and scaffolding to support learner confidence

• Designing activities that reduce cognitive overload while increasing depth of thinking

• Adapting prompts and materials to the needs of Japanese learners

• Prioritizing clarity, organization, and purposeful communication

• Building lessons that work within authentic classroom constraints and student ability levels
