Academic Discussion: The Structure That Scores

The four moves

Roughly 130 to 160 words in total. The task minimum is 100 words, and posts much beyond 180 usually mean you have written a second reason instead of developing the first.

Move 2, engagement, is where the marks are

There are three ways to engage, and they are not equally strong.

Weakest: naming without content. I agree with Kaitlyn. This names a classmate and adds nothing. A rater reads it as a template, because it is.

Better: restating and extending. Kaitlyn is right that the revenue matters, and I would add that where the money goes is more important than how much of it there is. You have shown you read the post and you have moved the argument somewhere new.

Strongest: answering the objection. Mikhail's food desert point is the strongest argument against the tax, and I do not think supporters can dismiss it. But it is an argument about how the revenue is spent, not about whether the tax should exist. You have taken the opposing case seriously, named what is right about it, and then shown why it does not defeat your position.

The third move is what a discussion looks like among people who are actually thinking. It also protects you from the most common content failure on this task, which is writing as though the other side has no case.

Why that is a 2

Length: 63 words. Below the 100-word minimum, which by itself signals limited development.

I think sin tax is good idea. A position, which is the one thing this post does. Missing article (a good idea), and sin tax without an article is a second slip in five words.

Unhealthy food is very bad for the health and many people are eating it every day. This is a restatement of common knowledge, not a reason. It also would be true whether or not a tax existed, so it does not support the position. Are eating should be eat, since this is a general habit rather than an action in progress.

Government should do something about this problem because obesity is increase in all the world. Is increase should be is increasing. More importantly, should do something is not an argument for this particular something. A rater reading this cannot tell whether the writer understood that the question was about a tax specifically.

Also the money can be used for good things. This is Kaitlyn's point, unattributed and stripped of all detail. Kaitlyn said school lunch programmes and supermarket subsidies. Good things is what remains when you have read a post but not used it.

No classmate is named. No example. No engagement with the objection. The professor's question explicitly raised the fairness objection, and Mikhail developed it. Ignoring the strongest counter-argument when it has been placed in front of you is what makes this limited relevance rather than simply thin support.

Why that is a 3 and exactly what lifts it

In my opinion, cities should adopt a sin tax on unhealthy foods. Clear position in sentence one. Correct move, correct place.

I agree with Kaitlyn that these products cause serious health problems such as diabetes and heart disease. A classmate is named and her argument is restated accurately. This is real engagement and it is the strongest thing in the post. What stops it earning more is that the post agrees and stops. Nothing is added to what Kaitlyn already said.

and the tax would make people buy them less often. Asserted, not argued. Why would it? By how much? The mechanism is exactly what a band 5 post would spend two sentences on, and this post spends none.

Another reason is that governments need money for health programs, and this tax can provide it. Second reason, one sentence, undeveloped. This is the listing habit. Cutting this sentence entirely and using the words on the smoking example would raise the score.

In my country, cigarettes are taxed heavily and fewer young people smoke now than before. The best sentence in the post, and it is nearly wasted. An analogy between tobacco tax and food tax is a genuinely good argument, and it needed one more sentence explaining why the two cases are alike. As written it is dropped in and abandoned.

However, some people say it is unfair for poor families. This is a valid concern, but health is more important. Here is the ceiling. The professor raised the fairness objection and Mikhail developed it with the food desert argument. This post reduces all of that to some people say, then dismisses it in six words. Acknowledging a counter-argument without answering it is not engagement, and health is more important is an assertion that a critic would simply deny.

For these reasons I support the sin tax. Adequate close.

The single change that moves this to a 4: replace some people say it is unfair with Mikhail's point about food deserts, and answer it rather than dismissing it. That is one sentence of rewriting and it converts a template into a discussion.

Why that is a 4 and what is still missing

I think cities should adopt a sin tax, although the way the revenue is spent matters as much as the tax itself. A qualified position in the first sentence. The qualification is doing real work: it tells the reader in advance how this post will handle the objection, which is what organised means in the descriptor.

Kaitlyn is right that sugary drinks and fast food contribute directly to diabetes and heart disease, and that the revenue could pay for school lunch programs. Accurate restatement of a named classmate, including the specific detail from her post. Good engagement.

I would add that price is one of the few tools a city actually controls. This is the extension, and it is genuinely new. The post is no longer summarising the discussion, it is contributing to it. It is also the only sentence of extension in the post, which is part of why this stops at a 4.

Mikhail raises a fair objection about families in food deserts. That is a real problem, and I think the answer is to spend the revenue in those neighborhoods first rather than to drop the tax. Both classmates engaged, and the objection is answered rather than dismissed. Answering the objection at all is what lifts this clear of a 3.

So why is this a 4? Two reasons, and they compound. There is no concrete example anywhere in the post: every sentence sits at the level of general principle, and the band 5 descriptor asks for a well-elaborated contribution, which in a policy discussion means an instance a reader can picture. And each move is made once and then left. Kaitlyn gets one sentence of agreement, the extension gets one sentence, Mikhail's objection gets one sentence of answer. Adequate development is exactly what band 4 describes, and it is what separates this from the post below.

The fix is roughly thirty words. Name a place, a programme, a number, or a comparable policy that behaved the way you are predicting. The next model does exactly that and nothing else changes structurally.

Why that is a 5, line by line

I support a sin tax on unhealthy foods, but only if the revenue is committed in advance to the neighborhoods the tax draws most of its money from. Position and condition in one sentence. Committed in advance is precise vocabulary doing argumentative work, because the whole post turns on the difference between promising and committing.

Kaitlyn is right that price changes behavior, and Mikhail is right that the burden falls unevenly. Both classmates named in one clause, each summarised in six words. Economical engagement, and it sets up the next sentence.

Those two points are usually treated as opposite sides of the argument, and I think they are actually the same point seen from different ends. This is the strongest sentence in any of the four models. It does not pick a side between the classmates, it reframes their disagreement. That is what meaningful engagement with the discussion means at the top of the scale.

A tax works precisely because it is felt, and it is felt most by the people with the least room in their budget. That is not an accident of the policy, it is the mechanism. The mechanism, stated explicitly, and it concedes the uncomfortable part of its own position. Raters notice when a writer is willing to state the strongest version of the objection.

What decides whether that mechanism is fair is what happens to the money. A pivot sentence. Short, after two longer ones, which is sentence variety used structurally rather than decoratively.

Cities that have taxed sugary drinks and put the revenue into things residents can see, such as free school meals or a produce market in a neighborhood that had none, have kept public support. The concrete example the band 4 post lacked. Note that it does not need a citation or a statistic. It needs to be specific enough that a reader can picture it, and a produce market in a neighborhood that had none is.

Cities that let the revenue disappear into the general budget have faced repeal campaigns within a few years, and reasonably so, because in that case low-income families paid more and received nothing. The parallel case. Two contrasting outcomes make the claim testable rather than optimistic, and and reasonably so shows the writer applying the same fairness standard to their own side.

So my answer to Mikhail's objection is not that food deserts do not matter. It is that they decide where the money has to go. A close that restates the position through the objection rather than by repeating the opening sentence. Two short sentences after a long one.

Length: 208 words. Longer than necessary. A 160-word version of this post with the same moves would also be a 5. What earns the band is the reframing, the mechanism and the concrete contrast, not the word count.

The ten minutes, allocated

1. 1

   Minutes 1 to 2. Read and decide

   Read the professor's question, then both classmate posts. Decide your side immediately. There is no extra credit for the harder side, so take the one you can produce an example for. Then note which classmate you will answer and which you will extend.

2. 2

   Minute 3. Position and engagement

   Write move 1 and move 2 without stopping. These are the two moves with a fixed shape, so they should be fast. If you find yourself hunting for an elegant opening sentence, write the plain one and move on.

3. 3

   Minutes 4 to 7. Development

   The one paragraph that decides your band. Mechanism, then example, then the consequence if it were not true. Resist adding a second reason. If you finish early, deepen this paragraph rather than starting a new one.

4. 4

   Minute 8. Close

   One sentence restating the position with whatever qualification your argument earned. Do not introduce new content here.

5. 5

   Minutes 9 to 10. Check

   In this order: is a classmate named, is my example specific, is my position the same at the end as at the start, is the last sentence a complete sentence. Then and only then look at grammar.

Final check before the timer ends

• My position appears in the first sentence and again in the last.
• At least one classmate is named and their argument is restated in my own words.
• I answered an objection rather than dismissing it with a phrase like but health is more important.
• I developed one reason rather than listing three.
• My example is specific enough that a reader could picture it.
• The post is over 100 words.
• The final sentence is complete, not cut off mid-thought.
• No contractions, and no casual phrases such as a ton of or get into troubles.

What to practise first

If your discussion posts are sitting at a 3, the problem is almost never grammar. Take three of your old posts and check one thing in each: did you name a classmate and answer what they actually argued? Most students find the answer is no, or that they named someone and then agreed with them without adding anything.

Fix that single move and you will move to a 4 without changing your English at all. Then, and only then, work on grounding your reason in a concrete example, which is what takes a 4 to a 5.
