RESUMO

Reasoning is the derivation of new knowledge from old. The reasoner must represent both the old and new knowledge. This representation will change as reasoning proceeds. This change will not just be the addition of the new knowledge. We claim that the representation of the old knowledge will also often change as a side effect of the reasoning process. For instance, the old knowledge may contain errors, be insufficiently detailed or require new concepts to be introduced. Representational change triggered by reasoning is a common feature of human reasoning but it has been neglected both in Cognitive Science and Artificial Intelligence. We aim to put that right. We exemplify this claim by analysing Imre Lakatos's rational reconstruction of the evolution of mathematical methodology. We then describe the abduction, belief revision and conceptual change (ABC) theory repair system, which can automate such representational change. We further claim that the ABC system has a diverse range of applications to successfully repair faulty representations. This article is part of a discussion meeting issue 'Cognitive artificial intelligence'.

RESUMO

This review provides a critique of David Ausubel's theory of meaningful learning and the use of advance organizers in teaching. It takes into account the developments in cognition and neuroscience which have taken place in the 50 or so years since he advanced his ideas, developments which challenge our understanding of cognitive structure and the recall of prior learning. These include (i) how effective questioning to ascertain previous knowledge necessitates in-depth Socratic dialogue; (ii) how many findings in cognition and neuroscience indicate that memory may be non-representational, thereby affecting our interpretation of student recollections; (iii) the now recognised dynamism of memory; (iv) usefully regarding concepts as abilities or simulators and skills; (v) acknowledging conscious and unconscious memory and imagery; (vi) how conceptual change involves conceptual coexistence and revision; (vii) noting linguistic and neural pathways as a result of experience and neural selection; and (viii) recommending that wider concepts of scaffolding should be adopted, particularly given the increasing focus on collaborative learning in a technological world.

RESUMO

This study used two training sessions and two focus groups with 17 preservice teachers (aged 20-36) completing their first teaching practicum placement during their Bachelor of Education program at an urban research university in western Canada. The aim was to implement ideas from terror management theory (TMT) during their teaching practicum. Participants explored how to facilitate contentious issues so as to prevent defensive reactions when worldviews clash in the classroom. A dramaturgical analysis identified participant objectives, conflicts, tactics, attitudes, emotions, and subtexts as they explored how to anticipate and avoid worldview and self-esteem threat, navigate tense pedagogical spaces, build capacity for expressing uncomfortable emotions, and diffuse threat with humor. Because difficult emotions are central to teaching potentially polarizing content, participating preservice teachers explored when compensatory reactions might emerge and, as a result, developed their own emotional awareness-TMT became both an experience and a teachable theory.

RESUMO

It is of great importance that science educators teach COVID-19 and related pandemics to boost students' scientific literacy. A mixed methods research design (pre-post test instrument [N = 86] and semi-structured interviews [N = 11]-August 2020 to June 2021) evaluated the ability of an intervention (12 h, three-session, 3-day, online workshop) to augment middle school inservice science teachers' (Eastern Saudi Arabian province) ability to teach about medical terminology and the epidemiology of diseases. Teachers' cognitive gains were measured through evaluating their knowledge, comprehension, and application of workshop content before and after the intervention. Descriptive statistics and inferential t tests revealed statistically significant cognitive differences overall (p < .01) (posttest mean = 26.26/30, SD 2.83, t value 18.51) and along knowledge (posttest mean = 5.72/7), comprehension (mean = 7.50/8), and application (mean = 13.05/15). A high effect size coefficient n2 indicated a large effect on cognitive gains. Thematic analysis about participants' subsequent efforts teaching workshop content to students revealed positive and negative experiences. The former included improved student engagement with the curriculum, community connections via project-based learning, and opportunities to teach colleagues about COVID-19. The latter concerned insufficient time, an obligation to teach the current curriculum without adding COVID-19 content, and administrative resistance. Recommendations pertain to augmenting the workshop curriculum and likeminded research initiatives.

RESUMO

Intuitive conceptions represent common obstacles to conceptual learning in science. A growing number of studies demonstrate that when learning occurs, these intuitive conceptions are not replaced by scientific conceptions but rather coexist with them and thus need to be inhibited to prevent systematic errors. However, to date no study has demonstrated that the increasing ability to mobilize a given scientific conception is rooted in the increasing ability to inhibit the intuitive conception that interferes with it. In the current study, we investigated whether the increasing ability from childhood to adulthood to solve a scientific problem regarding the buoyancy of marbles of different sizes and densities is rooted in the increasing ability to inhibit the "bigger objects sink more" intuitive conception. To do so, we designed a negative priming paradigm in which 11-year-old children, 17-year-old adolescents, and 24-year-old adults were asked to choose which of two marbles of various sizes and densities sinks more. Negative priming effects reported in children and adolescents suggest that, unlike adults, they must inhibit the "bigger objects sink more" intuitive conception to determine, for instance, that a small marble with high density (e.g., small lead marble) will sink more than a bigger marble with a lower density (e.g., big wooden marble). We also found that the amplitude of negative priming effects decreased with age, suggesting that the level of exposition to the scientific knowledge of buoyancy (increasing with age) may decrease the need to inhibit the "bigger objects sink more" intuitive conception.

RESUMO

In problem-based learning (PBL), the steps and processes present in the PBL tutorial cycle are essential for constructive, self-directed, collaborative, and contextual student learning. This article presents a procedural study of a PBL tutorial cycle with high school students new to the method regarding human respiration and circulation physiology. We observed group dynamics and the learning process that occurred throughout the PBL tutorial cycle. The results indicate that conceptual changes were close to the planned learning objectives and that students enjoyed studying applying PBL. Moreover, a positive correlation was observed between group dynamics, self-directed learning and learning outcomes. Our results provide grounds for restructuring the tutorial cycle, especially important for novice PBL students, such as problem reformulation and the development and diversification of applied learning scaffolds. We conclude that the qualitative analysis performed herein can yield a deeper understanding of the PBL tutorial cycle and may be used to foster PBL implementation in institutions with little experience with the method and monitor its outcomes in organizations with mature PBL use.

RESUMO

This paper investigates the emergence of conformational analysis in organic chemistry as a case of conceptual change in science. In this case, the mechanism of conceptual change is identified as the emergence of a new exemplar. This new exemplar was made possible because of the identification of a distinctive chemical structure to which 'foothold' concepts were applicable. These concepts facilitated both clear explanation in the particular case, and the analogical extension of the conceptual innovation throughout the discipline. The case suggests a cognitive explanation for the importance of exemplars to scientific content.

RESUMO

The Cognitive Reflection Test (CRT) is a widely used measure of adults' propensity to engage in reflective analytic thought. The CRT is strongly predictive of many diverse psychological factors but unsuitable for use with developmental samples. Here, we examined a children's CRT, the CRT-Developmental (CRT-D), and investigated its predictive utility in the domains of science and mathematics. School-age children (N = 152) completed the CRT-D, measures of executive functioning, measures of rational thinking, and measures of vitalist-biology and mathematical-equivalence concepts. CRT-D performance predicted conceptual understanding in both domains after we adjusted for children's age, executive functioning, and rational thinking. These findings suggest that cognitive reflection supports conceptual knowledge in early science and mathematics and, moreover, demonstrate the theoretical and practical importance of children's cognitive reflection. The CRT-D will allow researchers to investigate the development, malleability, and consequences of children's cognitive reflection.

RESUMO

When asked to say whether an agent is morally good or bad, younger preschoolers tend to rely more on the outcomes of agents' actions than on agents' intentions, whereas older children show the opposite bias. Children aged 3 to 5 years were examined with a novel task that facilitated the selection and expression of response by means of response generation training. In two experiments, we found that 3-year-olds succeeded in generating intent-based judgments when the task was simplified, whereas older preschoolers succeeded also without the help of response generation training. Results are inconsistent with views positing a conceptual change occurring in the moral domain at about 4 years of age and provide support for alternative accounts positing conceptual continuity.

RESUMO

BACKGROUND: In medical physiology, educators and students face a serious challenge termed misconceptions. Misconceptions are incorrect ideas that do not match current scientific views. Accordingly, they have shown to hamper teaching and learning of physiological concepts. Conceptual Change Theory forms the basis of new teaching and learning practices that may alleviate misconceptions and facilitate critical thinking skills that are essential in becoming knowledgeable, self-regulated health professionals. In this study, we examined if such an intervention named refutation texts, could enhance medical students' cognition and metacognition. METHODS: First-year medical students (N = 161) performed a pre-test and post-test on cardiovascular physiology concepts, including a self-perceived confidence rating. In between, students read either a standard text with an explanation of the correct answer, or a refutation text which additionally refuted related misconceptions. RESULTS: In both groups, average performance scores (refutation: + 22.5%, standard: + 22.8%) and overall confidence ratings (refutation: Δ0.42 out of 5, standard: Δ0.35 out of 5) increased significantly (all p < .001), but a significant effect of the specific refutation element was not found. Initially incorrect answers were corrected less frequently in cases of high confidence (35.8%) than low confidence (61.4%). CONCLUSIONS: Our results showed that refutation texts significantly increased students' knowledge, however, the refutation element did not have a significant additional effect. Furthermore, high confidence in incorrect answers negatively affected the likelihood of correction. These findings provide implications for teaching practices on concept learning, by showing that educators should take into account the key role of metacognition, and the nature of misconceptions.

RESUMO

Rapid and radical changes in science, technology and society may result in new scientific concepts and new workplace practices, which require fundamental restructuring of prior knowledge. Over the years a noteworthy body of research has documented the processes of conceptual change, the learning mechanisms involved, and the instructional methods and strategies that can promote conceptual changes. This research, however, focused young learners in school settings. Conceptual changes in working life go beyond traditional conceptual change consisting of processes and mechanisms that involve the interaction between expertise development and workplace learning processes.This Special Issue investigates whether and how conceptual change research can be extended from learning in schools to learning in professional life.

RESUMO

Phenomenon: This qualitative inquiry used conceptual change theory as a theoretical lens to illuminate experiences in medical school that trigger professional identity formation. According to conceptual change theory, changes in personal conceptualizations are initiated when cognitive disequilibrium is introduced. We sought to identify the experiences that trigger cognitive disequilibrium and to subsequently describe students' perceptions of self-in-profession prior to the experience; the nature of the experience; and, when applicable, the outcomes of the experience. Approach: This article summarizes findings from portions of data collected in a larger qualitative study conducted at a new medical school in the United States that utilizes diverse pedagogies and experiences to develop student knowledge, clinical skills, attitudes, and dispositions. Primary data sources included focus groups and individual interviews with students across the 4 years of the curriculum (audio data). Secondary data included students' comments from course and end-of-year evaluations for the 2013-2017 classes (text data). Data treatment tools available in robust qualitative software, NVivo 10, were utilized to expedite coding of both audio and text data. Content analysis was adopted as the analysis method for both audio and text data. Findings: We identified four experiences that triggered cognitive disequilibrium in relationship to students' perceptions of self-in-profession: (a) transition from undergraduate student to medical student, (b) clinical experiences in the preclinical years, (c) exposure to the business of medicine, and (d) exposure to physicians in clinical practice. Insights: We believe these experiences represent vulnerable periods of professional identity formation during medical school. Educators interested in purposefully shaping curriculum to encourage adaptive professional identity development during medical school may find it useful to integrate educational interventions that assist students with navigating the disequilibrium that is introduced during these periods.

RESUMO

The purpose of this study was to explore and reveal naïve conceptions and misconceptions about energy embedded in elementary school students' prior knowledge. Students' performance on standardized knowledge test was used to classify students into low, median and high levels of knowledge about the cardiovascular system. Semi-structured in-depth interviews were conducted with students in each group to extract their understanding of energy in relation to food choices, physical activities, and exercises. Analysis of the interview data generated six categories of naïve conceptions and two categories of misconceptions. Different conceptual change theories, including Chi's ontological change theory, Ohlsson's resubsumption theory, and enculturation theory were used to analyze and understand these naïve conceptions and misconceptions and why they could be robust to change. The analyses confirm the need to adopt a multi-theoretical approach to the understanding of students' naïve conceptions and misconceptions (Chinn & Samarapungavan, 2009. Conceptual change-multiple routes, multiple mechanisms: A commentary on Ohlsson. Educational Psychologist, 44(1), 1-10). The findings encourage physical and health educators adopt different strategies to address the potential learning obstacles brought by students' naïve conceptions and misconceptions.

RESUMO

A large body of cognitive research has shown that people intuitively and effortlessly reason about the biological world in complex and systematic ways. We addressed two questions about the nature of intuitive biological reasoning: How does intuitive biological thinking change during adolescence and early adulthood? How does increasing biology education influence intuitive biological thinking? To do so, we developed a battery of measures to systematically test three components of intuitive biological thought: anthropocentric thinking, teleological thinking and essentialist thinking, and tested 8th graders and university students (both biology majors, and non-biology majors). Results reveal clear evidence of persistent intuitive reasoning among all populations studied, consistent but surprisingly small differences between 8th graders and college students on measures of intuitive biological thought, and consistent but again surprisingly small influence of increasing biology education on intuitive biological reasoning. Results speak to the persistence of intuitive reasoning, the importance of taking intuitive knowledge into account in science classrooms, and the necessity of interdisciplinary research to advance biology education. Further studies are necessary to investigate how cultural context and continued acquisition of expertise impact intuitive biology thinking.

RESUMO

Recent accounts of number word learning posit that when children learn to accurately count sets (i.e., become "cardinal principle" or "CP" knowers), they have a conceptual insight about how the count list implements the successor function - i.e., that every natural number n has a successor defined as n+1 (Carey, 2004, 2009; Sarnecka & Carey, 2008). However, recent studies suggest that knowledge of the successor function emerges sometime after children learn to accurately count, though it remains unknown when this occurs, and what causes this developmental transition. We tested knowledge of the successor function in 100 children aged 4 through 7 and asked how age and counting ability are related to: (1) children's ability to infer the successors of all numbers in their count list and (2) knowledge that all numbers have a successor. We found that children do not acquire these two facets of the successor function until they are about 5½ or 6years of age - roughly 2years after they learn to accurately count sets and become CP-knowers. These findings show that acquisition of the successor function is highly protracted, providing the strongest evidence yet that it cannot drive the cardinal principle induction. We suggest that counting experience, as well as knowledge of recursive counting structures, may instead drive the learning of the successor function.

RESUMO

Semantic knowledge is a crucial aspect of higher cognition. Theoretical accounts of semantic knowledge posit that relations between concepts provide organizational structure that converts information known about individual entities into an interconnected network in which concepts can be linked by many types of relations (e.g., taxonomic, thematic). The goal of the current research was to address several methodological shortcomings of prior studies on the development of semantic organization, by using a variant of the spatial arrangement method (SpAM) to collect graded judgments of relatedness for a set of entities that can be cross-classified into either taxonomic or thematic groups. In Experiment 1, we used the cross-classify SpAM (CC-SpAM) to obtain graded relatedness judgments and derive a representation of developmental changes in the organization of semantic knowledge. In Experiment 2, we validated the findings of Experiment 1 by using a more traditional pairwise similarity judgment paradigm. Across both experiments, we found that an early recognition of links between entities that are both taxonomically and thematically related preceded an increasing recognition of links based on a single type of relation. The utility of CC-SpAM for evaluating theoretical accounts of semantic development is discussed.

RESUMO

Scientific ideas can be difficult to access if they contradict earlier-developed intuitive theories; counterintuitive scientific statements like "bubbles have weight" are verified more slowly and less accurately than closely-matched intuitive statements like "bricks have weight" (Shtulman & Valcarcel, 2012). Here, we investigate how context and instruction influences this conflict. In Study 1, college undergraduates (n = 100) verified scientific statements interspersed with images intended to prime either a scientific interpretation of the statements or an intuitive one. Participants primed with scientific images verified counterintuitive statements more accurately, but no more quickly, than those primed with intuitive images. In Study 2, college undergraduates (n = 138) received instruction that affirmed the scientific aspects of the target domain and refuted common misconceptions. Instruction increased the accuracy of participants' responses to counterintuitive statements but not the speed of their responses. Collectively, these findings indicate that scientific interpretations of a domain can be prioritized over intuitive ones but the conflict between science and intuition cannot be eliminated altogether.

RESUMO

Although children learn more when teachers gesture, it is not clear how gesture supports learning. Here, we sought to investigate the nature of the memory processes that underlie the observed benefits of gesture on lasting learning. We hypothesized that instruction with gesture might create memory representations that are particularly resistant to interference. We investigated this possibility in a classroom study with 402 second- and third-grade children. Participants received classroom-level instruction in mathematical equivalence using videos with or without accompanying gesture. After instruction, children solved problems that were either visually similar to the problems that were taught, and consistent with an operational interpretation of the equal sign (interference), or visually distinct from equivalence problems and without an equal sign (control) in order to assess the role of gesture in resisting interference after learning. Gesture facilitated learning, but the effects of gesture and interference varied depending on type of problem being solved and the strategies that children used to solve problems prior to instruction. Some children benefitted from gesture, while others did not. These findings have implications for understanding the mechanisms underlying the beneficial effect of gesture on mathematical learning, revealing that gesture does not work via a general mechanism like enhancing attention or engagement that would apply to children with all forms of prior knowledge.

RESUMO

Previous research has shown that naïve views of math and science concepts coexist with more formal views. The current study extended this finding to the domain of mathematical equivalence and tested whether inhibitory control relates to using more formal views over naïve ones. In the current study, we report two experiments in which undergraduate students (n = 125 for Study 1 and n = 184 for Study 2) completed a priming task involving inhibitory control and math items, an inhibitory control flanker measure, and a comprehensive mathematical equivalence assessment. We found quantitative and qualitative evidence that adults hold both naïve operational views and formal relational views of equivalence across multiple measures and under timed and untimed conditions. In contrast to our hypotheses, we did not find evidence to support a strong association between individual differences in inhibitory control and mathematical equivalence knowledge. The results call into question the role of this domain-general cognitive skill in contributing to adults' expression of naïve operational thinking.

RESUMO

We propose a simple computational model that describes potential mechanisms underlying the organization and development of the lexical-semantic system in 18-month-old infants. We focus on two independent aspects: (i) on potential mechanisms underlying the development of taxonomic and associative priming, and (ii) on potential mechanisms underlying the effect of Inter Stimulus Interval on these priming effects. Our model explains taxonomic priming between words by semantic feature overlap, whereas associative priming between words is explained by Hebbian links between semantic representations derived from co-occurrence relations between words (or their referents). From a developmental perspective, any delay in the emergence of taxonomic priming compared to associative priming during infancy seems paradoxical since feature overlap per se need not be learned. We address this paradox in the model by showing that feature overlap itself is an emergent process. The model successfully replicates infant data related to Inter Stimulus Interval effects in priming experiments and makes testable predictions.
