2. Linda is 31 years old, single, outspoken, and very bright. She majored in • philosophy. As a student, she was deeply concerned with issues of discrimination and social justice, and also participated in anti nuclear demonstrations. • (Kahneman & Tversky 1982, p.496). • A. Linda is a bank teller • B. Linda is a bank teller who is active in the feminist movement. Psychology students choosing B as the most probable statement: 86% of the undergraduate students 50% of the graduate students

3. A description of the dilemma First I thought a), according to the rules for determining the probability of a true statement, but then I thought that I was supposed to draw conclusions from the text describing Linda and thus I chose b). Now, however, I realize I was wrong! A good reason assay Since Linda had been involved so much in issues of discrimination and social equality while at school, I thought she'd be inclined to carry on the "struggle" later on in her working life. A deliberate choice between statistics and good reason assay I chose a) because that way I'm neither assuming too much nor too little. A safer judgement. The risk of being prejudiced or making generalisations determined my choice of a). ... Maybe it wouldn't have been wrong to say that she belonged to the feminist movement, but it might not have been right either, so I left it out.

4. Another deliberate choice Initial comment "An academic grade in philosophy does not land you a job in a bank, the feminist movement speaks for b)." Comment after the presentation of the statistical solution "From now on I'll have to take everything's probability into account, but in this case I don't intend to change my mind."

11. Concept and conception We cannot isolate the contribution of conceptual content from the beliefs we hold about the entities that fall under a concept (concepts as distinct from conceptions). (Carey, 2011 p. 123). Concept “to describe a grouping of objects or behaviours with the same defining features that has become recognised through research or widespread use” (Entwistle, 2007, p.2) Conception “Indicates individuals’ different ways of thinking about a particular grouping” (Ibid., p. 2) Conception is “all the knowledge that a person has, and associates with, the concept’s name” (White, 1994, p.118)

12. What we are studying in conceptual research, then, is conceptions and the change of conceptions. we are studying the learner’s conception of the same entity, or similar entities, as the scientific concept denotes. “To understand a concept “should rather be expressed by “to have a conception is to understand the same that is understood by a concept” Having a scientific conception depends on similarities with the scientific concept

13. Concept and conception similarities? idiosyncratic conception scientific concept territory area of description/explanation social and cultural situation time

14. ‘negative rationalism’ (Rommetveit, 1978) characterised by a predominant focus on students’ shortcomings, difficulties and general fallibility. ‘theories of difficulty’ (Perkins, 2005) What do students do when they fail?

15. Behaviour gets its intentional character from being seen by the agent himself or by an outside observer in a wider perspective, from being set in a context of aims and cognitions. This is what happens when we construe a practical inference to match, as premises match a given conclusion. (Emphasis in original, von Wright, 1971,p. 115)

16. P 1 A person P intends to bring about x (where x is a verb or a verb-phrase) in situation s. P 2 P believes that she or he can bring about x, in situation s, by doing y (where y is a verb or a verb-phrase). C Thus, P does y.

Elsevier, 1999, based on von Wright 1971, 1974, 1979 and 1980).

22. On the impossibility of living on an earth in space Two conceptions: one of the earth in sky and another one of the place where we live The children “know” that the earth is up in space. Thus, I cannot live there because I am living down here on the ground a logical contradiction Things down here are so big that there are no space for them on earth Information that has to be taken into account, i.e. issues to be solved: Astronomical aspects of the earth as, eg., being up there I am living here The logical contradiction Size relations

23. On the avoidance of the logical contradiction Three different ways to maintain coherence: Avoiding to locate the earth or avoiding to talk about the surroundings of the earth. 2. Denying the earth up in the sky, but then also the astronomical aspects of the earth. 3. Keeping the two locations apart as different places, often as different countries. Information that has to be taken into account, i.e. issues to be solved: Astronomical aspects of the earth as, e.g., being up there The conception of country A new logical contradiction

24. On the possibility for other people to live on earth Still two conceptions, but now with an attempt to relate them to each other Other people than me are living on earth It is possible to go to the earth, also for me. Long distance travels by air. Information that has to be taken into account, i.e. issues to be solved: The earth is up in the sky People are living on earth I am living down here People are living in countries

25. On the impossibility of living on the surface of the earth surrounded by space The hollow sphere model The compelling conditions for the hollow sphere: a) The earth in space and the place down here is the same place. b) It is impossible to live in space

26. Examples of information that has to be taken into account, i.e. issues to be solved We are “weightless and then one can just float away.” “you are in space and then you fly away. You can’tbreathe” “One should not get any air” “Other planets can hit your head” “And some planets might be hard.” “The kids can be scared” because it is dark in space. “It’s so cold in space “, “you can’t take cold air, then you will die”

27. On the possibility of living on the surface of the spherical earth surrounded by space A kind of normative model • We cannot live inside the earth because • There is lava inside • There are so many countries in the world • The world is so big These issues have to be solved and are now solved by a spherical earth It is possible to live on the surface because “We’re stuck”, there is a “kernel” inside the earth; thus, some kind of gravitation “There’s something blocking”; thus a conception of some kind of atmosphere that protects us from falling off and that makes it possible to breath - “The globe is big. That’s why it is so flat”; the earth is so huge

28. To summarize so far The great amount of issues actualized the differences in dignity of these issues The accidental occurrences of these issues in becoming of importance within the children’s problem solving activities in what ways they became combined In order for a conceptual change to come about, it looks like there are several issues requiring a simultaneous solution in order to make sense in the new conception to be acquired All this taken together speaks for a view on conceptual change as a highly multi determined process also involving processes of chance. Also, the results suggest that a lot of effort should be put upon understanding the reasoning in the learner before we try to challenge the learner with conflicting evidence in order to initiate a conceptual change.

29. Cognitive conflict and incoherence “Equilibration is achieved in…three forms: between the subject and the objects, between schemes or subschemes on the same hierarchic level, and between their differentiations and their integrations into superior totalities.” (Piaget, 1977, p. 30) • Between the subject and the objects, cognitive conflict: • - anomalous data (Chinn & Malhotra, 2002; • Echevarria, 2003; Mason, 2000, 2001) • discrepant events (Baddock & Bucat, 2008; Nussbaum & Novick, 1982; • Tsai, 2003) • - refutational texts (Guzzetti, 2000; Hynd, 2001; Mason, Gava, & Boldrin, 2008) • Within a conceptual structure, incoherence: • logical incoherence • contradictory beliefs • extension or change of explanatory field
