Argumentation is the process of supporting a position with arguments.
\n→ a position is the claim at the highest level: the answer to a polarising question (e.g. "No.").
\nan argument is used to justify (rather than explain) a claim or to persuade others of it
\n| Part | \nWhat it does | \nGuiding question | \n
|---|---|---|
| Claim | \nstates what is asserted | \nWhat is asserted? | \n
| Reason | \nsays why the claim holds | \nWhy? ("because …") | \n
| Evidence | \nbacks the reason | \nWhat shows this? | \n
| Warrant | \nconnects the reason to the claim | \nWhat must one accept for the reason to count? | \n
a statement presented as true or right that others can question
\n→ Empirical claims can be checked against data and the scientific knowledge base.
\n"Claim" can mean different things in different contexts.
\n→ Make explicit which kind of claim learners are dealing with.
\nwhat backs the reason of an argument
\n| Category | \nType | \nWhat it is | \nHow it can be judged | \nExample | \n\n |
|---|---|---|---|---|---|
| Empirical | \nData | \nmeasurements, studies, statistics | \ncan be verified; can be checked against the scientific knowledge base | \n"A regional study found lower sale prices for houses with a view of turbines." | \n\n |
| \n | Expert statements | \nstatements by people with relevant expertise | \ncan be judged for the expert’s credibility; can be traced back to the data they rest on | \n“A planning expert says that property prices recover within a few years.” | \n\n |
| Non-empirical | \nPersonal experience | \nthe speaker's own observations | \ncan be judged for credibility; not generalisable | \n"Where I used to have an open view of the hills, all I see now are turbines." | \n\n |
| Values | \nshared principles, often laid down in norms or laws | \ncan be judged for legitimacy | \nThe German Federal Nature Conservation Act (§ 1) requires nature and landscape to be protected "also in responsibility for future generations". | \n\n | |
| Interests | \nwhat the speaker or their group gains or loses | \ncan be judged for legitimacy | \n"As homeowners, we would lose a large part of our savings." | \n\n | |
| Emotions | \nfeelings the speaker reports | \ncan be taken seriously, not verified | \n"Every time I look out of my window now, I feel like a stranger in my own village." | \n\n |
Only empirical evidence can be checked against the scientific knowledge base. Arguments based on values, interests, emotions, or personal experience are still relevant to socio-scientific issues: their legitimacy has to be discussed and considered, not verified.
\nAn expert statement is mediated evidence: what it’s worth depends on what it rests on.
\nReported vs. evoked emotions: An argument that reports the speaker's own feelings is legitimate. An argument that evokes emotions in the audience to bypass critical thinking is a manipulation strategy (e.g. "Imagine your children growing up between grinding turbines!").
Polarising question: Should wind farms be built in protected landscapes to help the shift to clean energy?
Stakeholder: local resident · Position: No (binary)
Together, the three arguments and the position form the resident's viewpoint.
\nhow the arguments of an information item are arranged
\nan explanation is used to make sense of a phenomenon based on other scientific facts to generate understanding
\n→ essential to creating new knowledge (nature of science)
\nCER (Claim – Evidence – Reasoning; McNeill & Krajcik 2012) is widely used in school science to help students construct scientific explanations.
\n| Part | \nWhat it does | \nGuiding question | \n
|---|---|---|
| Claim | \nconclusion about a phenomenon | \nWhat happens? | \n
| Empirical Evidence | \nprovides data that support the claim – appropriate and sufficient | \nWhich data show this? | \n
| Reasoning | \nexplains why the data count as evidence for the claim, using a scientific principle | \nWhich principle explains it? | \n
Explanations and arguments serve different purposes (Osborne & Patterson 2011). CER was developed for scientific explanations. An explanation accounts for a phenomenon that is not in dispute: it links data to a scientific principle to show why something happens (e.g. Plants grow faster in more light – light provides the energy for photosynthesis.) → nature of science. An argument justifies a claim that is contested and could be answered differently, e.g. a position on a polarising question. → Use Claim – Evidence – Reasoning to explain empirical findings. → Use Claim – Reason – Evidence – Warrant to argue for a position.
\n→ In socio-scientific issues, the line between explanation and argument can blur. The debate is then not about the explanation itself, but about which of several competing explanations is valid (e.g. human activity vs. natural variation as the cause of rising global temperatures). Sometimes the debate goes further and disputes the phenomenon itself (e.g. that global temperatures are rising at all).
