After the Last Table: Teaching the Reading Move from Findings to Meaning

Scientific papers are often read as if they speak in a single voice. A pupil moves from abstract to method, from table to conclusion, and assumes that the text is simply reporting what happened. Yet a scientific report changes its work as it proceeds. At some point it stops saying what was observed and begins arguing what the observations mean. That shift — the Results–Discussion turn — is one of the most important reading moves in science, and one of the least visible.

For pupils in UK science classrooms, recognising this turn matters well beyond the reading of published papers. It shapes how they interpret required practical write-ups, how they answer extended-response questions, and how they judge claims in science news. The argument of this article is that the turn should be taught explicitly, not left to the intuition of able readers.

Two kinds of sentence

Consider two sentences a pupil might meet in a report on reaction rates.

The mean volume of gas collected in the first minute increased as the concentration of acid increased.

The pattern suggests that particle collisions become more frequent as concentration rises.

The first sentence reports a relationship within the data. It is accountable to the table: a reader can check the values, the conditions and the range tested. The second sentence interprets that relationship. It invokes a model — collision theory — that is not itself present in the measurements. Both sentences are legitimate science, but they do different work. The first says what was found; the second says what might be inferred.

Pupils often treat such sentences as interchangeable. They may copy the second as if it were a result, or dismiss the first as mere description. Neither response captures the discipline of scientific reading. The Results–Discussion turn is precisely the point at which a writer moves from warranting a claim by data to warranting it by argument.

Why the turn is hard to see

In many published papers, the boundary is marked by headings. In classroom writing, examination responses and shorter reports, it often is not. The prose continues, the paragraphs look similar, and the reader must detect the change without typographic help. Three features make the turn especially difficult.

First, scientific writing uses hedging. Words such as suggests, indicates, is consistent with and may reflect are not signs of weakness. They are calibrated claims. But to a pupil looking for certainty, they can appear as vague or unimportant. Second, verb tense shifts. Procedures and observations are often reported in the past tense, while interpretations and established knowledge tend towards the present. This is a tendency, not a rule, and pupils need to read it as a clue rather than a formula. Third, the agent changes. In the Results, the data or the apparatus may be the grammatical subject: the temperature rose, the titre fell, the current increased. In the Discussion, the writer or the findings become more prominent: these results suggest, this pattern indicates, it is likely that.

None of these signals is decisive on its own. Together, they form a readable pattern.

A routine for the classroom

A useful routine begins with locating the turn rather than explaining the science. Ask pupils to underline the last sentence that could be checked directly against a table or figure. Then ask them to underline the first sentence that offers a reason, a model or a consequence beyond the data. The gap between those two sentences is the reading space of the Results–Discussion turn.

A second pass looks for signal phrases. Pupils can collect the verbs and connectives that carry interpretive weight: suggests, indicates, implies, is consistent with, therefore, however, these findings. The aim is not to produce a list to memorise but to notice how writers announce a change in warrant. A sentence containing suggests is usually doing different work from a sentence containing showed.

A third pass asks two questions of the interpretive sentences. What evidence is being invoked? What would count against the interpretation? This last question is particularly valuable. It prevents the Discussion from being read as a second Results section. It also teaches pupils that scientific interpretation is not arbitrary: it is answerable to evidence, even when it goes beyond it.

From GCSE to A-level

At GCSE, the routine can be introduced through practical write-ups. Pupils might separate a paragraph into two columns: what we observed and what we think it means. A sentence such as the temperature rose most quickly in the first two minutes belongs in the first column. A sentence such as this shows that the reaction was fastest at the start belongs in the second, and pupils can discuss why the word shows may be too strong without further evidence.

At A-level, the same routine can be extended to longer reports and past papers. Pupils can examine how writers qualify claims, how they acknowledge anomalies, and how they distinguish correlation from mechanism. They can compare a Results sentence with a Discussion sentence from the same study and ask what each would need to be accepted. This is not a detour from content. It is a way of making content usable.

The reader's gain

The Results–Discussion turn is not a decorative feature of scientific style. It is where science becomes explicit about its own reasoning. Pupils who can spot the turn are better placed to separate evidence from interpretation, to judge the strength of a claim, and to write their own reports with greater control. They are also less likely to read a paper as a monologue of facts. Instead, they begin to hear the disciplined conversation that scientific writing actually is.

For Science in Reading, the implication is straightforward. Comprehension in science is not only a matter of vocabulary or background knowledge. It is also a matter of recognising the moves that writers make. The turn after the last table is one such move, and it deserves a place in the classroom.
