When one of my friends asked me on how to write a Discussion Chapter for his thesis, I quickly remembered what I used in my thesis: Toulmin Argument.
I employed this concept into my Discussion Chapter of my thesis (Interplay between social bonds and metacognition in learning science) to build a strong, fair, and persuasive argument.
Stephen Toulmin who developed this model realised that in real-life situations, arguments are rarely direct and straight-forward. Instead, they are inherently complex and nuanced. That is why, to present one’s idea in a convincing way, it is important to back the assertion with solid proof, clear reasoning, and right context.
As Discussion chapter is where we argue what our findings mean, I recommended my friend the Toulmin’s Model because it allows one to do exactly what a good discussion requires.
Briefly, a good Discussion needs to:
· State one’s idea or point (Claim).
· Support one’s idea with the data or evidence (Grounds).
· Explain why the data proves one’s claim (Warrant).
· Connect it to other literature or theories (Backing).
· State limitations of one’s study (Qualifier)
· Address the exceptions (Rebuttal).
Toulmin Elements
There are 6 parts in Toulin’s model of argument:
Claim,
Grounds,
Warrant,
Backing,
Qualifier, and
Rebuttal.
Claim
Claim is the main assertion or conclusion that one is trying to prove. It is therefore, the main point or argument made by the author.
The Claim in my thesis is:
Metacognition and social bonds are mutually reinforcing (working hand in hand).
How students metacognitive enact in achieving their shared goal or task entirely depends on the quality of social bonds (social relationships) they share.
This is the central message I have projected in my entire thesis, of course, backed with evidence and explanations.
Grounds
This is the hard evidence, data, or facts that support the claim.
I used my findings including the empirical or theoretical reasons to back up my Claim that social bonds and metacognition are mutually reinforcing.
My data shows:
When students feel safe and trust each other (strong or healthy bonds), they think together more deeply. They talk openly about what they are trying to do, work out how to get there, and keep an eye on each other's progress. That kind of teamwork gets results.
In contrast, when trust is broken or missing (broken bonds), students still think, but they do it more quietly and carefully. They hold back, avoid real collaboration, and slowly withdraw from the group. The thinking happens, but it does not go very far.
My data also shows that feeling emotionally safe with each other is what unlocks the deeper conversations, where students actually question, challenge, plan, and reflect together, rather than just going through the motions.
This is not a new idea. Researchers in metacognition have long argued that thinking about our own thinking does not happen in isolation. It is shaped by the people around us and the relationships we share with them.
My data indicate that the quality of social bonds (social and emotional connection) directly affect students' thinking (metacognition) enactment.
Warrant
This is the logical reasoning that connects the proof (Ground) with the main point or assertion (Claim).
The warrant in my thesis state:
When students feel genuinely close to each other, something important happens. They feel safe enough to be open, to depend on one another, and to actually tune in to how each other is feeling. That emotional safety is what makes real thinking together possible.
In that kind of environment, students are willing to take risks with their thinking. They speak up even when they are unsure, challenge ideas, and let others help them think things through. That is where the real collaborative thinking happens.
And the stronger those bonds are, the more thinking becomes a shared experience rather than an individual one. It stops being something each student does alone in their head and becomes something they do together, out loud, and with purpose.
Through this statement, I explain why my Ground justifies the Claim by connecting the two theoretical ideas of social bonds and metacognition using a social bond theory as the bridge.
Backing
Backing is using the expert knowledge from the literature of established theories that give support the Warrant. It shows that reasoning is based on existing knowledge and not just a personal opinion.
In my case, I used existing theories of Social Bonds and Metacognition which were used as conceptual framework in my study:
Social Bond Theory (Scheff (1997) explains that when people feel emotionally connected, trusted, and respected by those around them, they are able to engage openly without the fear of being judged, shamed, or shut out. That sense of security is not just optional. It is a necessary condition for genuine engagement. Applied to the classroom, this supports the idea that students need to feel emotionally safe with each other before they can truly regulate their thinking together.
In metacognition research, it has begun to explore metacognition as a process shaped by social interactions. Studies focused on constructs such as collaboration, group work, and peer learning consistently show that metacognitive processes do not always live inside one person’s head. They emerge between people, through conversation, through checking in on each other, and through planning together. Thinking about thinking, in other words, is often a shared and relational act.
These theoretical knowledge explain what was observed in the classroom (reinforce my Warrant). Emotional safety, rooted in secure social bonds, is what opens the door for students to think deeply and reflectively with one another.
Qualifier
The Qualifier sets the conditions or limits of the Claim. It shows that the relationship being argued does not apply in every situation. Doing this helps preventing overgeneralisation of the argument.
In my study, the Qualifier made clear that the mutually reinforcing relationship between social bonds and metacognition mainly happens in learning contexts where emotional connections, mutual respect, and relational stability (strong bonds) are present.
This means that strong social bonds do not exist automatically in every classrooms, nor do they always lead to productive metacognitive engagement. Their influence depends on how relationships are actually built and maintained within the learning environment.
Rebuttal
The Rebuttal recognises situations where the Claim may not apply. It acknowledges that there may be exceptions or circumstances that could weaken the argument.
In my thesis, the Rebuttal acknowledge that metacognition can still occur in groups where social bonds are broken or disrupted.
However, in such situations, metacognition tends to become individualised, cautious, or defensive. It becomes less social and mutual, even if students continue to work together to complete a task.
Students may still engage in self-monitoring or strategy selection which are forms of metacognition. But collective regulation may be weakened by the fear of judgement, withdrawal from dialogue, or lack of trust.
As a result, shared metacognitive processes may become less developed and less effective, which can affect the quality of collaborative learning.
By breaking down these elements, one's argument becomes theoretically robust, balanced, and credible.
While not claiming absolute perfection, adopting this structure allowed my Discussion Chapter to move beyond just describing what happened. It enabled me to explain exactly how and when social bonds shape students' metacognition in science learning.
