Informal reasoning fallacies are arguments that are psychologically persuasive but not valid. In order to judge the validity of these arguments one has to be sensitive to the context in which they appear. However, there is no empirical study that examines students' sensitivity to contextual factors and whether contextual factors actually influence their ability to identify informal reasoning fallacies. We hypothesized that when explicitly presented with different argumentative contexts, students' performance would reflect their sensitivity to the contextual nature of informal reasoning fallacies. The two experiments that we conducted support this hypothesis and emphasize the mediating role of perspective taking in students' ability to identify fallacious arguments.  相似文献

Informal reasoning fallacies are arguments that, though they may seem persuasive, are not valid. The psychological aspect of informal reasoning fallacies, specifically the identification of factors that influence students' ability to identify fallacies, has not been the subject of empirical study. The aim of this study was to test the hypothesis that subjects' ability to identify fallacious arguments is associated with the representation of the argumentative text in the cognitive system. In the first experiment, we tested the hypothesis through a recall task. In the second experiment, we tested the hypothesis through a classification task. The results of the experiments confirm the research hypothesis and point to the role of argumentative structures in argumentation tasks.  相似文献

Informal reasoning fallacies are arguments that are psychologically persuasive but not valid. In the context of informal reasoning fallacies, the truth-value of the reason in support of a given claim is irrelevant to judging the validity of the argument as a whole. This property stands in sharp contrast with the general role of the reason's truth-value in judging arguments in general. The aim of this study was to test the hypothesis that in the context of informal reasoning fallacies the truth-value of a reason influences pupils' judgment of the extent to which the reason supports the claim. The results of the study confirm the research hypothesis.  相似文献

The ability to evaluate scientific claims and evidence is an important aspect of scientific literacy and requires various epistemic competences. Readers spontaneously validate presented information against their knowledge and beliefs but differ in their ability to strategically evaluate the soundness of informal arguments. The present research investigated how students of psychology, compared to scientists working in psychology, evaluate informal arguments. Using a think-aloud procedure, we identified the specific strategies students and scientists apply when judging the plausibility of arguments and classifying common argumentation fallacies. Results indicate that students, compared to scientists, have difficulties forming these judgements and base them on intuition and opinion rather than the internal consistency of arguments. Our findings are discussed using the mental model theory framework. Although introductory students validate scientific information against their knowledge and beliefs, their judgements are often erroneous, in part because their use of strategy is immature. Implications for systematic trainings of epistemic competences are discussed.  相似文献

Growth mindset interventions directed at students aim to change students' beliefs about the malleability of ability. These interventions have had mixed results, with some showing impressive findings (e.g., improving grades and persistence in science and closing performance gaps), while other implementations have shown null findings. This heterogeneity suggests that growth mindset interventions should not be viewed as a sole solution for improving educational outcomes for students and that further research is needed to identify the contextual factors that influence their effectiveness. We propose new theoretical directions in mindset research that adopts an anti-deficit model and moves away from focusing exclusively on students and their belief systems. Instead, we encourage a new wave of mindset research that considers the institutional, cultural, and contextual environment that either corroborates or negates students' mindset beliefs. We propose a new approach to mindset research that emphasizes innovative approaches to better understand the conditions under which mindset interventions are effective.  相似文献

Classical informal reasoning "fallacies," for example, begging the question or arguing from ignorance, while ubiquitous in everyday argumentation, have been subject to little systematic investigation in cognitive psychology. In this article it is argued that these "fallacies" provide a rich taxonomy of argument forms that can be differentially strong, dependent on their content. A Bayesian theory of content-dependent argument strength is presented. Possible psychological mechanisms are identified. Experiments are presented investigating whether people's judgments of the strength of 3 fallacies--the argumentum ad ignorantiam, the circular argument or petitio principii, and the slippery slope argument--are affected by the factors a Bayesian account predicts. This research suggests that Bayesian accounts of reasoning can be extended to the more general human activity of argumentation.  相似文献

Suppressing valid inferences with conditionals   总被引:7,自引:0,他引:7  
R M Byrne 《Cognition》1989,31(1):61-83
Three experiments are reported which show that in certain contexts subjects reject instances of the valid modus ponens and modus tollens inference form in conditional arguments. For example, when a conditional premise, such as: If she meets her friend then she will go to a play, is accompanied by a conditional containing an additional requirement: If she has enough money then she will go to a play, subjects reject the inference from the categorical premise: She meets her friend, to the conclusion: She will go to a play. Other contexts suppress the conditional fallacies. The first experiment demonstrates the effects of context on conditional reasoning. The second experiment shows that the inference suppression disappears when the categorical premise refers to both of the antecedents, such as: She meets her friend and she has enough money. In this case, subjects make both the valid inferences and the fallacies, regardless of the contextual information. The third experiment establishes that when subjects are given general information about the duration of a situation in which a conditional inducement was uttered, such as: If you shout then I will shoot you, they reject both the valid inferences and the fallacies. The results suggest that the interpretation of premises plays an even more central role in reasoning than has previously been admitted.  相似文献

This paper argues that some traditional fallacies should be considered as reasonable arguments when used as part of a properly conducted dialog. It is shown that argumentation schemes, formal dialog models, and profiles of dialog are useful tools for studying properties of defeasible reasoning and fallacies. It is explained how defeasible reasoning of the most common sort can deteriorate into fallacious argumentation in some instances. Conditions are formulated that can be used as normative tools to judge whether a given defeasible argument is fallacious or not. It is shown that three leading violations of proper dialog standards for defeasible reasoning necessary to see how fallacies work are: (a) improper failure to retract a commitment, (b) failure of openness to defeat, and (c) illicit reversal of burden of proof.  相似文献

Background . Recent research on achievement motivation has begun to examine the effects of environmental factors affecting students' motivational beliefs and goal tendencies. However, when interpreting and applying the results, individual factors underlying students' different perceptions of their learning environment are often ignored. An implicit assumption seems to be that regardless of their dispositional differences (e.g. motivational basis), students will experience and benefit from instructional practices in the same way. Aims . This paper highlights the importance of students' dispositional motivational factors when examining differences in their perceptions of and preferences for the learning environment. The study builds on a conception of student motivation that emphasizes the interaction of individual and contextual factors. Sample and method . Questionnaires served as self‐report tools and assessed students' achievement goal orientations, self‐esteem, causality beliefs, academic withdrawal and perceptions of and preferences for the learning environment. The sample consisted of 208 sixth grade elementary school students. Results . Based on latent class cluster analysis and one‐way analyses of variance, it was found that students' perceptions of and preferences for the learning environment vary depending on differences in students' motivational tendencies. Conclusions . Students' dispositional motivational characteristics should be taken into account both in theoretical considerations and in instructional interventions.  相似文献

There is a long, rich history of arguments for the importance of involving students in a process of inquiry. For many instructors, however, promoting student inquiry is a difficult agenda to pursue for two reasons. First, there is often tension for instructors between concerns for this agenda and more traditional concerns for the correctness and completeness of students' understanding. Second, it is not easy to recognize when productive student inquiry is taking place. For a teacher in class, what is valuable about the students' participation at any given moment may not be as obvious as what is flawed and ambiguous in their arguments. For this article, I analyze a short excerpt from a high school physics class discussion to consider the value of the students' work as inquiry and to illustrate a teacher's negotiation of the tension between inquiry and traditional content-oriented concerns. In this way, I try to discover the beginnings of science in what the students say and do, rather than to apply criteria from a particular model of scientific reasoning. This exploration for students' knowledge and abilities is offered both as an approach to research on student inquiry and as a mode of instructional practice to support that inquiry.  相似文献

School connectedness refers to students' beliefs that their peers and adults at school care about their learning and themselves as individuals. School connectedness has been widely documented as a significant predictor for positive student outcomes, yet little is known about factors associated with it as an outcome variable. Guided by the advocating student-within-environment framework situated with the social development model, this study explored individual and contextual factors associated with school connectedness among 1,201 students in Grades 4 to 8. Gender, ethnicity, grade level, and social skills were found to be significant individual factors, whereas school support for learning and acceptance of diversity were significant contextual factors. Together, the individual and contextual factors explained 47% of the variance in school connectedness. Our findings also revealed grade-related variability concerning associations between the factors and school connectedness. These findings provide further insights into fostering connectedness in the context of counseling in schools with consideration to students' developmental needs.  相似文献

The world’s scientific community must be in a state of constant readiness to address the threat posed by newly emerging infectious diseases. Whether the disease in question is SARS in humans or BSE in animals, scientists must be able to put into action various disease containment measures when everything from the causative pathogen to route(s) of transmission is essentially uncertain. A robust epistemic framework, which will inform decision-making, is required under such conditions of uncertainty. I will argue that this framework should have reasoning at its center and, specifically, that forms of reasoning beyond deduction and induction should be countenanced by scientists who are confronted with emerging infectious diseases. In previous articles, I have presented a case for treating certain so-called traditional informal fallacies as rationally acceptable forms of argument that can facilitate scientific inquiry when little is known about an emerging disease. In this article, I want to extend that analysis by highlighting the unique features of these arguments that makes them specially adapted to cope with conditions of uncertainty. Of course, such a view of the informal fallacies must at least be consistent with the reasoning practices of scientists, and particularly those scientists (viz. epidemiologists) whose task it is to track and respond to newly emerging infectious diseases. To this end, I draw upon examples of scientific reasoning from the UK’s BSE crisis, a crisis that posed a significant threat to both human and animal health.

We present a methodology for designing better learning environments. In Phase 1, 6th-grade students' (n = 223) prior knowledge was assessed using a difficulty factors assessment (DFA). The assessment revealed that scaffolds designed to elicit contextual, conceptual, or procedural knowledge each improved students' ability to add and subtract fractions. Analyses of errors and strategies along with cognitive modeling suggested potential mechanisms underlying these effects. In Phase 2, we designed an intervention based on scaffolding this prior knowledge and implemented the computer-based lessons in mathematics classes. In Phase 3, we used the DFA and supporting analyses to assess student learning from the intervention. The posttest results suggest that scaffolding conceptual, contextual, and procedural knowledge are promising tools for improving student learning.  相似文献

Classroom practices that make ability differences salient communicate differential teacher expectations for students. This study reports on a new observational tool for measuring Classroom Ability-based Practices (CAP) and explores how young children's self-perceptions of ability in mathematics are related to their teachers' expectations for them and to their cognitive reasoning skills in classrooms that vary in usage of such ability-differentiated practices. The sample consisted of 193 children and their teachers in 15 first grade classrooms. The CAP was a reliable measure of ability-based differential teacher treatment and showed criterion validity as a moderator variable in predicting children's ability perceptions. In highly ability-differentiating classrooms, children's self-ratings were more congruent with teachers' expectations of students' mathematics ability. Also in highly ability-differentiating classrooms, higher cognitive levels predicted lower self-ability ratings in math. These findings extend our understanding of the social and cognitive factors that shape young children's self-judgments of math competence.  相似文献

What should a virtue theory of argumentation say about fallacious reasoning? If good arguments are virtuous, then fallacies are vicious. Yet fallacies cannot just be identified with vices, since vices are dispositional properties of agents whereas fallacies are types of argument. Rather, if the normativity of good argumentation is explicable in terms of virtues, we should expect the wrongness of bad argumentation to be explicable in terms of vices. This approach is defended through analysis of several fallacies, with particular emphasis on the ad misericordiam.  相似文献

Fallacies     
Fallacies are things people commit, and when they commit them they do something wrong. What kind of activities are people engaged in when they commit fallacies, and in what way are they doing something wrong? Many different things are called fallacies. The diversity of the use of the concept of a fallacy suggests that we are dealing with a family of cases not related by a common essence. However, we suggest a simple account of the nature of fallacies which encompasses them all, viz., the term “fallacy” is our most general term for criticizing any general procedure used for the fixation of beliefs that has an unacceptably high tendency to generate false or unfounded beliefs, relative to that method of fixing beliefs. Very different sorts of things called fallacies are examined in the light of this account, e.g., denying the antecedent, circular arguments, so-called informal fallacies, and propositions said to be fallacies. We do not provide a theory of fallacies. Still, on our account pretty much all of those things that have been called fallacies are fallacies, and they have been called fallacies for pretty much the same reasons.  相似文献

One hundred and twelve undergraduate university students completed an informal reasoning task in which they were asked to generate arguments both for and against the position they endorsed on three separate issues. Performance on this task was evaluated by comparing the number of arguments they generated which endorsed (myside arguments) and which refuted (otherside arguments) their own position on that issue. Participants generated more myside arguments than otherside arguments on all three issues, thus consistently showing a myside bias effect on each issue. Differences in cognitive ability were not associated with individual differences in myside bias. However, year in university was a significant predictor of myside bias. The degree of myside bias decreased systematically with year in university. Year in university remained a significant predictor of myside bias even when both cognitive ability and age were statistically partialled out. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献

Being unreasonable: Perelman and the problem of fallacies   总被引:1,自引:0,他引:1  
Most work on fallacies continues to conceptualize fallacious reasoning as involving a breach of a formal or quasi-formal rule. Chaim Perelman's theory of argumentation provides a way to conceptualize fallacies in a completely different way. His approach depends on an understanding of standards of rationality as essentially connected with conceptions of universality. Such an approach allows one to get beyond some of the basic problems of fallacy theory, and turns informal logic toward substantive philosophical questions. I show this by reinterpreting three so-called fallacies - theargumentum ad baculum, equivocation and composition/division - in the light of Perelman's account.  相似文献

This article presents the results of two experiments addressing the relation of reasoning skill to student grade, ability, and knowledge levels. In the first experiment, three levels of students within each of four grades-5, 7, 9, or 1 1-were designated as intellectually gifted, average, or below average. They were given three tasks involving everyday problems for which they provided solutions and justifications. The second experiment included the measurement of domain knowledge with grade and ability level. Measures of informal reasoning showed a substantial relation between ability level and performance, with knowledge significantly related to performance measures, such as number and type of reasons generated, but not to measures involving soundness or acceptability of arguments, which were explained by ability level. Grade was related only to an increase in personal and broadly defined social reasons; other effects were "washed out" by knowledge. The findings were interpreted in terms of a two-component model of informal reasoning, a knowledgeexperiential component and an informal reasoning skill component based on the acquisition of argumentation-based language structures termed conventions of reasoning. Consideration of the relation of reasoning to learning and to instruction emphasized the importance of teaching informal reasoning skill.  相似文献
