According to Piaget, a fundamental epistemological distinction must be made between the psychological and the epistemic subject. The epistemic subject is studied by the genetic epistemologist who charts development through a “common universal rationality, which develops,” whereas the psychological subject is studied by the developmental/cognitive psychologist by focusing on accidental contingencies surrounding particular people and their individual differences. The epistemic subject as compared to the psychological subject is an idealized abstraction, viz., that set of underlying epistemic structures common to everyone at the same level of development. The objective of this study is to investigate the degree to which investigators in science education conceptualize the difference between the epistemic and the psychological subjects. It is argued that just as the ideal gas law (based on the theoretical formulation of Maxwell and Boltzmann) provides a “general model” to which the real gases approximate under different experimental conditions, so we can consider (by abduction) the epistemic subject to be an “ideal knower” to which the real (psychological) subjects approximate to varying degrees. The difference between the epistemic and the psychological subjects, however, cannot be used as an “epistemological shield” in defense of Piagetian theory. Any test of the Piagetian theory must involve psychological or real subjects. Empirical testability, however, need not be equated to being scientific. An analogy is drawn between Galileo's idealization, which led to the discovery of the law of free-fall, and Piaget's epistemic subject. Research conducted in science education shows that at least for some critics the wide variations in the age at which individuals acquire the different Piagetian stages is crucial for rejecting the theory. It is argued that the real issue is not the “proportion of heterogeneity” but the understanding that Piaget, by neglecting individual differences, attempts to build a general model applicable across types of situations/subjects. The distinction between the epistemic and the psychological subjects is important not for defending Piaget's theory (which has serious theoretical flaws) but to understand epistemic transitions, for example, the one between Piaget's epistemic subject and Pascual-Leone's metasubject. It is concluded that failure to understand the distinction between the epistemic and the psychological subjects would lead to misconstruing the significance of our research findings and, what is more serious, to a lack of a historical perspective. 相似文献

Niaz (1990) presents arguments in favor of the retention of Piaget's epistemic subject as a theoretical construct to guide research and practice in science education and psychology. The intent of this article is to point out the weaknesses of those arguments and to suggest that the weight of evidence argues against the existence of the logical thinker postulated by Piaget. Therefore, contrary to Niaz's conclusion that the acceptance of Piaget's epistemic subject will facilitate the development of cognitive theories with greater explanatory power, the conclusion is reached that Piaget's epistemic subject is dead and that continued acceptance of this aspect of Piagetian theory would be counterproductive. 相似文献

Piaget's theory has profoundly influenced science education research. Following Piaget, researchers have focused on content-free strategies, developmentally based mechanisms, and structural models of each stage of reasoning. In practice, factors besides those considered in Piaget's theory influence whether or not a theoretically available strategy is used. Piaget's focus has minimized the research attention placed on what could be called “practical” factors in reasoning. Practical factors are factors that influence application of a theoretically available strategy, for example, previous experience with the task content, familiarity with task instructions, or personality style of the student. Piagetian theory has minimized the importance of practical factors and discouraged investigation of (1) the role of factual knowledge in reasoning, (2) the diagnosis of specific, task-based errors in reasoning, (3) the influence of individual aptitudes on reasoning (e.g., field dependence-independence), and (4) the effect of educational interventions designed to change reasoning. This article calls for new emphasis on practical factors in reasoning and suggests why research on practical factors in reasoning will enhance our understanding of how scientific reasoning is acquired and of how science education programs can foster it. 相似文献

Tests of formal operational reasoning derived from Piagetian theory have been found to be effective predictors of academic achievement. Yet Piaget's theory regarding the underlying nature of formal operations and their employment in specific contexts has run into considerable empirical difficulty. The primary purpose of this study was to present the core of an alternative theory of the nature of advanced scientific reasoning. That theory, referred to as the multiple-hypothesis theory, argues that tests of formal operational reasoning actually measure the extent to which persons have acquired the ability to initiate reasoning with more than one specific antecedent condition, or if they are unable to imagine more than one antecedent condition, they are aware that more than one is possible; therefore conclusions that are drawn are tempered by this possibility. As a test of this multiple-hypothesis theory of advanced reasoning and the contrasting Piagetian theory of formal operations, a sample of 922 college students were first classified as concrete operational, transitional, or formal operational, based upon responses to standard Piagetian measures of formal operational reasoning. They were then administered seven logic tasks. Actual response patterns to the tasks were analyzed and found to be similar to predicted response patterns derived from the multiple-hypothesis theory and were different from those predicted by Piagetian theory. Therefore, support was obtained for the multiple-hypothesis theory. The terms intuitive and reflective were suggested to replace the terms concrete operational and formal operational to refer to persons at varying levels of intellectual development. 相似文献

The Cambridge Primary Review's (CPR) preference for a Vygotskian model of schools learners and learning rather than a Piagetian is queried. There are weaknesses and uncertainties with major Vygotskian ideas such as the ‘zone of proximal development’, ‘internalisation’, ‘joint construction’, ‘language mediation’ and educational acculturation, relative to the Piagetian, while human scientific research with babies suggesting inherited capability thrust humans forearmed into physical and social worlds gives some succour to Piaget's cause. The Vygotskian and CPR premise that teachers can push learners beyond developmentally set limits is not unadulterated good news, depending on how we judge education's acculturation purposes and depending on the kind of learners we want within our educational system. 相似文献

Piaget's learning theory on cognitive development has had considerable impact on science education (Piaget, 1964; Inhelder and Piaget, 1958; Craig, 1972). The theory classifies cognitive learning into four successive stages: (a) sensory-motor, (b) pre-operational, (c) operational, and (d) formal. Various programmes and instructional strategies have been developed based on the theory (Batt, 1980; Karplus, 1977; Renner and Stafford, 1979; Ryan, et al., 1980; Herron, 1978; Good et al; 1978). An application of this theory for teaching and learning scientific concepts is the Piagetian learning cycle (Karplus, 1977) which is of growing interest among science educators. This article intends to introduce briefly the learning cycle in general and suggest a learning cycle for teaching a topic in chemistry: “Elements and Symbols”. 相似文献

This paper seeks to explain learning by examining five theories of learning—conceptual analysis, behavioural, constructivist, computational and connectionist. The first two are found wanting and rejected. Piaget's constructivist theory offers a general explanatory framework (assimilation and accommodation) but fails to provide an adequate account of the empirical mechanisms of learning. Two theories from cognitive science offering rival explanations of learning are finally considered; it is argued that the brain is not like a computer so the computational model is rejected in favour of a neurally‐based connectionist model of learning. 相似文献

Classical Piagetian theory had much to offer education, which could not be derived from the learning theory of its day. Since the cognitive revolution, learning theory has accepted most of Piaget's basic constructivist premises and outstripped his theory in its ability to model the details of children's cognitive structures. Thus, an important question is whether Piagetian theory still has anything distinctive to offer. To support the claim that it does, the notion of a central conceptual structure is introduced. These structures have several features that make their discovery in the context of learning theory unlikely, most notably their generality, the wide range of content domains that they span and their susceptibility to general developmental as well as specific experiential influence. Educational areas in which analysis of central conceptual structures has proven useful include (a) assessment, (b) early childhood education, (c) curriculum design, and (d) remedial instruction. 相似文献

Fifty-nine second-year medical students were asked to solve 12 Piagetian formal operational tasks. The purpose was to describe the formal logical characteristics of this medical student sample (59 of a total 65 possible) in terms of their abilities to solve problems in four formal logical schemata-combinatorial logic, probabilistic reasoning, propositional logic, and proportional reasoning. These tasks were presented as videotape demonstrations or in written form, depending on whether or not equipment manipulation was required, and were scored using conventional, prespecified scoring criteria. The results of this study show approximately 96% of the sample function at the transitional (Piaget's 3A level) stage of formal operations on all tasks and approximately 4% function at the full formal (Piaget's 3B level) stage of formal operations on all tasks. This sample demonstrates formal level thinking to a much greater degree than other samples reported in the literature to date and suggests these students are adequately prepared and developed to meet the challenge of their training (i.e., medical problem solving). 相似文献

An attempt is made to reconsider the implications of Piaget's theories for the teaching of reading. It is argued that the way the theories have typically been interpreted in relation to reading is unhelpful and does not accord with the behaviour of young readers. Alternative ways of linking Piagetian theory to the teaching of reading are proposed. It is considered that they both provide a more adequate explanation and offer the teacher more helpful directions along which to develop reading. 相似文献

Cross cultural studies of cognitive development that use the Piagetian paradigm are not new. In the past ten to fifteen years, both in Africa and Asia there have been extensive studies carried out on children from a variety of cultures. From the purely developmental viewpoint, research that is undertaken on different cultural groups has been a vital factor in substantiating some of Piaget's theoretical claims. The most important of these being that the development of.children's intellectual capacities undergo a universal sequence of development and that cultural factors are determinants in the univer-salistic process. 相似文献

Abstract: Kohlberg's system of moral judgment development has some important links with Piaget's work on moral judgment, though Piaget's work is not the only influence on Kohlberg's ideas. Piaget's system of moral growth is briefly examined, and the extent to which subsequent research has validated it, is noted, thus placing Kohlberg in a historical context. The ways in which Kohlberg extends or departs from Piaget's system of moral growth are examined. The concept of stages and the nature and processes of stage development are discussed, and in this context the relationship between Kohlberg's moral development and Piaget's cognitive development is examined. It is concluded on the basis both of logic and evidence that the relationship, although complex rather than isomorphic, is likely to hold considerable potential for future research. 相似文献

Most Piagetian formal operational reasoning tasks show horizontal decalage; that is, subjects pass certain tasks and fail others that have the same logical structure. The study reported here analyzes the importance of individual difference variables, as postulated by the neo-Piagetian theory of Pascual-Leone, in explaining subject performance in formal reasoning. A sample of 72 freshman students were administered a test of formal reasoning having 20 items of different types of reasoning, and the tests of the individual difference variables. Results obtained from multiple regression analyses show that Pascual-Leone's structural M-capacity (Ms) is the most consistent predictor of success in the different formal reasoning tasks, followed by Witkin's cognitive style, and to a much lesser degree Raven's progressive matrices, and Pascual-Leone's functional M-capacity (Mf). It was found that in the total score on the 20 items of formal reasoning, Ms accounted for 23.3% of the variance (R = 0.483, F = 6.39, p = 0.014) and Witkin's Group Embedded Figures Test, increased the multiple R significantly (F = 7.77, p = 0.007) and accounted for 7.6% of the variance. Mf and the Raven test did not make a significant contribution to the regression equation. Correlation coefficients among most of the items having the same reasoning pattern but different content are generally low but statistically significant (p < 0.01). Intercorrelations among items having the same formal reasoning pattern and content are fairly high (p < 0.001). These results emphasize the importance of individual difference variables: information-processing capacity (Pascual-Leone) and oversensitivity to potentially misleading information (Witkin). It is suggested that in order to understand student performance in formal reasoning tasks, we should expect horizontal decalages as a rule and not the exception, as Piaget had postulated. Educational implications are drawn. 相似文献

Cognitive performance on “An Inventory of Piaget's Developmental Tasks” (IPDT) was related to the Scholastic Aptitude Tests and performance in both college chemistry lecture and laboratory classes. The IPDT is a valid and reliable 72-item, untimed, multiple-choice paper-and-pencil inventory. It has 18 subtests grouped into five problem areas representing different Piagetian tasks. Subjects (n = 225) from two different levels of introductory chemistry courses participated. IPDT scores were significantly correlated with SAT and placement data. In overall Piagetian development, “A” students rated higher than others. Performance in classification and proportional reasoning problem areas correlated with course achievement, particularly for higher-level students. Weakest areas of development were indicated by subtest scores and are described with implications for course performance. Finally, Piagetian tasks were related to learning and instructional activities in introductory chemistry classes and are discussed. 相似文献

Research findings in learning disabilities based on Piaget's theory were reviewed. Superimposing the findings of research on Piagetian stages of cognitive development, it appears that during the sensorimotor stage the diagnosis of learning disabilities is difficult. The research findings suggest that there is a delay in cognitive development of learning-disabled children during elementary school years, which corresponds to preoperational, concrete operational, and transition to formal operational stages. From a genetic epistemological perspective, research evidence supports a “developmental lag” approach to learning disabilities. Implications for assessment, curriculum planning, and education are discussed. 相似文献

Conclusions The main feature of Piaget & Garcia's study (1989) is the overture of a new field of research within the Piagetian framework, namely the comparative study of individual and historical development.During the 80's, several alternative models have been offered to account for the relations between individual and historical development. However, it has been suggested that there [...] appears to be widespread agreement among Piagetians and non-Piagetians that common mechanisms and processes underlie the thinking of scientists and children at all times (Gauld 1990, p. 24–5).The development of this field of research demands that theoretical research be conducted regarding the possible patterns of relationship between individual and historical development, that should be integrated to comparative empirical research on diverse topics. Further studies would then be required to provide an empirical basis for the comparative research. In other words, this field of research demands the close collaboration between epistemologists, historians, science educators, and cognitive psychologists.We have suggested that the Piagetian model needs to provide a more convincing account of the differences between individual and historical development, and of the role of internal and external factors in the progress of science. We have also argued for an overcoming of the overemphasized structural aspects of the theory, and for an unambiguous concept of history.The non-Piagetian approaches have their own strength and may be developed as alternatives to the Piagetian model. However, our intention here is to emphasize their potential contribution to the development of Piaget's theory. In McCloskey and Kargon (1988) we may find hints to deal with the specificity of similarities in content. Nersessian (1987) provided an excellent insight on how to deal with Kuhn's concept of incommensurability. 5 In our interpretation, Carey's work suggest that considering the relation between content and development of structures may be a productive way of developing Piaget's theory.Finally, we would like to comment on the relationship between Piaget's theory and research on students' thinking in science. Both adopt a constructivist stance. However, the vast majority of researchers have developed a strong resistance to Piaget's theory (e.g. Novak 1978; Gilbert and Swift 1985). On the one hand, this resistance should be considered a natural and healthy tendency toward a pluralistic development of research in science education. On the other hand, it may be a consequence of the difficulty of Piaget's theory in coping with the main research findings on spontaneous reasoning. In short, while many researchers in science education have emphasized the persistence of children's, adolescents' and adults' alternative conceptions, Piaget's theory suggests that reaching the formal stage is a necessary condition to understand science. This contradiction will not be overcome while Piagetian researchers are not able to offer a better account of the differences between commonsense knowledge and scientific knowledge. Freed from the constraints of the Piagetian approach, research on alternative conceptions showed an amazing development during the late 70's and the 80's. 6,7 Further progress, however, increasingly requires theoretical tools to manage the great amount of data already available, and models to explain, rather than just describe, individuals' thought. This task can be carried out from within different theoretical approaches. In Psychogenesis and the History of Science, Piaget and Garcia presented an updated and strong model for the relationship between individual and historical development. If used in an open-minded way, this model may contribute to the development of research in science education.This study was supported by Conselho Nacional de Desenvolvimento Científico e Tecnológico/Brazil. 相似文献

Recent research shows that research programmes (quantitative, qualitative and mixed) in education are not displaced (as suggested by Kuhn) but rather lead to integration. The objective of this study is to present a rationale for mixed methods (integrative) research programs based on contemporary philosophy of science (Lakatos, Giere, Cartwright, Holton, Laudan). This historical reconstruction of episodes from physical science (spanning a period of almost 300 years, 17th to 20th century) does not agree with the positivist image of science. Quantitative data (empirical evidence) by itself, does not facilitate progress (despite widespread belief to the contrary), neither in the physical sciences nor in the social sciences (education) A historical reconstruction shows that both Piaget and Pascual‐Leone's research programs in cognitive psychology, follow the Galilean idealisation quite closely, similar to the research programs of Newton, Mendeleev, Einstein, Thomson, Rutherford, Millikan and Perl in the physical sciences. This relationship does not imply that researchers in education have to emulate research in the physical sciences. A major argument in favor of mixed methods (integrative) research programs is that it provides a rationale for hypotheses, theories, guiding assumptions and presuppositions to compete and provide alternatives. Similar to the physical sciences, this proliferation of hypotheses leads to controversies and rivalries, and thus facilitates the decision making process of the scientific community. It is concluded that mixed methods research programs (not paradigms) in education can facilitate the construction of robust strategies, provided we let the problem situation (as studied by practicing researchers) decide the methodology. 相似文献
