Abstract

Relying on developmental studies of reasoning about the good life, a model of moral education that integrates the good and the right is put forth. It is claimed that while Kohlberg's justice reasoning provides a justifiable aim for such curricula, how individuals attribute value will also significantly affect their moral actions. The notion of a ‘critical period’ for moral education during adolescence is also presented.  相似文献

Abstract

This paper reports a study of ‘connectedness’ vs ‘separateness’ orientation in adolescents’ reasoning on friendship, loyalty and understanding of political and social order. Conflict resolution in the connectedness orientation was found to focus on negotiation and an attempt to represent all points of view; in the separateness orientation the focus was on the advocacy of rules or codes of practice. There was a strong relationship between orientation and gender. The paper considers the implications of these findings for Gilligan's perspective of ‘two voices’, and for strategies for moral education.  相似文献

Key elements of the structure and function of models in mathematics and science are identified. These elements are used as a basis for discussing the development of model‐based reasoning. A microgenetic study examines the beginnings of model‐based reasoning in a pair of fourth‐ and fifth‐grade children who solved several problems about chance and probability. Results are reported in the form of a cognitive model of children's problem‐solving performance. The cognitive model explains a transition in children's reasoning from tacit reliance on empirical regularity to a form of model‐based reasoning. Several factors fostering change in children's thinking are identified, including the role of notations, peer interaction, and teacher assistance. We suggest that model‐based reasoning is a slowly‐developing capability that emerges only with proper contextual and social support and that future study should be carried out in classrooms, where these forms of assistance can also be part of the object of study.

Model‐based reasoning is a significant intellectual milestone because it bridges the worlds of personal, intuitive knowledge, on the one hand, and mathematical‐scientific theory, on the other. However, across disciplines, consensus is still forming about what model‐based reasoning comprises, and there is little knowledge about its ontogenetic origins or how it develops. We consider analogy as the core of modeling, because in model‐based reasoning a system in one domain is used to understand a system in another. To understand how models come to play a role in reasoning, it is important to initiate study of their origins. Accordingly, we report a microgenetic study examining the beginnings of model‐based reasoning in a pair of young children solving problems about chance and probability. In this study we are engaged in the enterprise of modeling the development of modeling. That is, we report our results in the form of a cognitive model of children's problem‐solving performance that explains a transition in reasoning from a tacit reliance on empirical regularity to a form of model‐based reasoning. It is important to note the two distinct meanings for the term model used in this article. The first describes how children come to understand and appropriate a system of reasoning exemplified in practices of modeling. The second describes a research tool, a model of human reasoning—specifically, how children in this study began to use models of probability to reason about uncertain events. In this report, we use the terms model or model‐based reasoning to refer to the former interpretation, whereas references to a cognitive model denote the simulation of children's thinking—in this case, implemented as a computer program.

Before describing the empirical work, we first identify some key elements of the structure and function of models. Next, these elements of modeling are used as the basis for generating some conjectures about the development of model‐based reasoning. We describe a task that we used as a window to understanding progression in student reasoning toward reliance on models as tools for thought. We present our rationale for developing cognitive models of student performance and explain some choices concerning the implementation of the cognitive model reported here. Finally, we turn to the children's performance on chance and probability tasks and explain how that performance illuminates both what children do not understand about models and the kinds of relevant knowledge that they are acquiring.  相似文献

Achievement in science depends among other factors on hypothetico‐deductive reasoning ability, that is, developmental level of the students. Recent research indicates that the developmental level of students should be studied along with individual difference variables, such as Pascual‐Leone's M‐capacity (information processing) and Witkin's Cognitive Style (disembedding ability). The purpose of this study is to investigate reasoning strategies of students in solving chemistry problems as a function of developmental level, functional M‐capacity and disembedding ability. A sample of 109 freshman students were administered tests of formal operational reasoning, functional M‐capacity, disembedding ability and chemistry problems (limiting reagent, mole, gas laws). Results obtained show that students who scored higher on cognitive predictor variables not only have a better chance of solving chemistry problems, but also demonstrated greater understanding and used reasoning strategies indicative of explicit problem‐solving procedures based on the hypothetico‐deductive method, manipulation of essential information and sensitivity to misleading information. It was also observed that students who score higher on cognitive predictor variables tend to anticipate important aspects of the problem situation by constructing general figurative and operative models, leading to a greater understanding. Students scoring low on cognitive predictor variables tended to circumvent cognitively more demanding strategies and adopt others that helped them to overcome the constraints of formal reasoning, information processing and disembedding ability.  相似文献

Abstract

In order to explore the relationship between moral reasoning and conduct, 38 Grade Six students, deemed by their teachers to display ‘delinquent’ or ‘non‐delinquent’ characteristics, were administered Kohlberg's Moral Judgment Instrument (Kohlberg et al., 1973) and an IQ test. Subjects were then randomly assigned to three treatment groups: a) experimental‐‐discussion of moral dilemmas; b) placebo‐‐social studies games; c) control. A month later Kohlberg's instrument was readministered.

Findings indicated that ‘delinquents’ and ‘non‐delinquents’ differed significantly (p = .001) on moral reasoning scores at both testing times. There was no statistically significant treatment effect (p = .06). Intelligence quotient was significantly and positively related to moral reasoning for ‘non‐delinquents’, but not for ‘delinquents’.  相似文献

Verbal and nonverbal forms of thinking exhibit widespread dissociation at neural and behavioral level. The importance of this for children's causal thinking and its implications for school science are largely unknown. Assessing 5‐ to 10‐year‐olds' responses (N = 231), verbal ability predicted causal reasoning, but only at lower levels, while nonverbal ability was the strongest predictor at higher levels of causal inference. We also distinguished between generic and scientific vocabulary use (n = 101). The results showed that use of scientific vocabulary predicted causal reasoning beyond generic, and connected more to nonverbal thinking. The findings highlighted the importance of elementary school science activities supporting application of nonverbal ability in thinking about causal processes; the benefits of linking nonverbal imagery to scientific vocabulary; and shortcomings in understanding of the forms/sources of nonverbal ability and their role in learning.  相似文献

Forty-seven fifth grade students (40 group-tested and 7 individually interviewed) read a text describing plate tectonics. At four points they drew diagrams of the spatial, causal, and dynamic processes inside the earth. These diagrams along with students' corresponding explanations, think-aloud protocols (for those individually interviewed), and answers to inference questions were analysed in order to characterize students' models of the interior of the earth, and models of its causal and dynamic processes. Types and characteristics of models, and reasoning associated with them are presented. Additionally, data from two exemplary students are presented as case studies. One student has considerable misunderstandings regarding both her understanding of the spatial layout of the interior of the earth and its causal mechanisms. The second student is more typical in terms of his initial models, but makes large gains in revising his understanding about the causal and dynamic processes inside the earth. In both cases, data are used to infer how each student used their diagrams as artefacts for externalizing knowledge, inference making, and model-revision.  相似文献

ABSTRACT

This paper discusses, compares, and contrasts 4 different models for bringing evidence from randomised controlled trials (RCTs) into practice and into practical reasoning. I look at what questions the models can and cannot answer, what role they accord to RCT evidence, and what their possible attraction for practitioners might be. The models are those of Philip Davies, Nancy Cartwright, Stephen Toulmin, and Harald Grimen. The first 2 are constructed for the purpose of using evidence in practice, the 3rd is an adapted argumentation model, and the 4th is based on phronesis and represents an alternative to evidence-based education. It is argued that of these, Toulmin’s model has the narrative qualities that make it the most usable and practitioner-friendly model.  相似文献

This study describes a lesson in which students engaged in inquiry in evolutionary biology in order to develop a better understanding of the concepts and reasoning skills necessary to support knowledge claims about changes in the genetic structure of populations, also known as microevolution. This paper describes how a software simulation called EVOLVE can be used to foster discussions about the conceptual knowledge used by advanced secondary or introductory college students when investigating the effects of natural selection on hypothetical populations over time. An experienced professor's use and rationale of a problem-based lesson using the simulation is examined. Examples of student misconceptions and naïve (incomplete) conceptions are described and an analysis of the procedural knowledge for experimenting with the computer model is provided. The results of this case study provide a model of how EVOLVE can be used to engage students in a complex problem-solving experience that encourages student meta-cognitive reflection about their understanding of evolution at the population level. Implications for teaching are provided and ways to improve student learning and problem solving in population genetics are suggested.  相似文献

Many theories and models describe the various cognitive processes individuals engage in as they solve ill-structured problems. While diverse in perspectives, these theories and models uniformly agree that essential aspects of complex problem solving include iteration and inquiry. This paper further argues that an important yet overlooked component of knowledge construction during problem-solving is the ability to ask meaningful questions. What is needed, but not adequately articulated and validated, is a theoretical taxonomy of question-asking to better understand and guide a learner’s reasoning process. Based on the expert–novice literature, we proffer the following question taxonomy: shallow/simple (verification, disjunctive, concept completion), testing (example, feature specification, quantification, definition, comparison), and deep/complex questions (interpretation, causal antecedent, causal consequence, goal orientation, instrumental/procedural, enablement, expectation, and judgmental). We, therefore, build on existing theories/models of problem-solving, failure, and reflection and their implications towards a taxonomy of question-asking. Given this taxonomy, researchers and designers can better understand learners’ level of understanding and problem-solving trajectories.

This article compares Enright's cognitive-developmental model of forgiveness (Enright et al., 1989, 1991, 1992, 1994) with a model of forgiveness based on communication between the wronged and the wrongdoer. While unilateral forgiveness is unconditional and is a process which happens wholly within the person who has suffered an injustice, negotiated forgiveness requires of the wrongdoer (1) confession; (2) ownership; and (3) repentance for their actions. Unilateral forgiveness is built upon the principle of identity; in contrast, negotiated forgiveness begins with, and extends Piaget's principle of ideal reciprocity. Enright's highest stage of forgiveness reasoning is one in which considerations of social context are transcended; in the model of negotiated forgiveness, such understanding of context is central. Whereas unilateral forgiveness is a wholly intraindividual phenomenon, negotiated forgiveness is quintessentially social and dynamic. Using the example of truth and reconciliation commissions, the article examines the implications for the relationship between justice and forgiveness, according to each model.  相似文献

The ideas of first year university students about measurement in the physics laboratory are explored. Student responses to written probes administered at the beginning of the year are compared to those written after a 12 week laboratory course. The 'point' and 'set' paradigms are used as a model to analyse the responses to the probes. At the heart of the point paradigm is that both action and reasoning are based solely on individual measurements in a data set. On the other hand, subscribing to the set paradigm implies an understanding that a series of measurements are to be viewed as a collective that can be modelled by theoretical constructs, such as the mean and standard deviation. The degree of consistent use of these paradigms by individual students across the sets of probes is investigated. Implications for effective teaching interventions in the physics laboratory are discussed.  相似文献

Abstract

Kohlberg's cognitive‐developmental theory provides teachers with a framework for understanding the change and development of moral judgment and decision‐making of their pupils. One major abuse, however, may be when teachers take the stage labels associated with the hypothesized stage levels of moral judgment as indicative of static student qualities or characteristics, by placing more emphasis on perceived and labelled qualities than on the actual moral reasoning of the student. This, it is suggested, together with some empirical examples, may obscure the developmental trend of the student's moral judgment or even affect the teacher's expectations and consequently student's performance, and fails to take into account such factors as environment and interpersonal interaction. A study is reported in which curriculum consultants exposed to moral development theory were tested to determine whether they would use Kohlbergian labels of stage content or actual moral reasoning when required to make assessments. Suggestions are put forward as to how moral development theory can be more closely linked to pedagogy.  相似文献

Background: There has been an increasing emphasis on empowering pre-service and in-service science teachers to attend student reasoning and use formative assessments to guide student learning in recent years. Purpose: The purpose of this study was to explore pre-service science teachers’ pedagogical capacity for formative assessment. Sample: This study took place in Turkey. The participants include 53 pre-service science teachers in their final year of schooling. All but two of the participants are female. Design and methods: We used a mixed-methods methodology in pursing this inquiry. Participants analyzed 28 responses to seven two-tiered questions given by four students of different ability levels. We explored their ability to identify the strengths and weaknesses in students’ answers. We paid particular attention to the things that the pre-service science teachers noticed in students’ explanations, the types of inferences they made about students’ conceptual understanding, and the affordances of pedagogical decisions they made. Results: The results show that the majority of participants made an evaluative judgment (i.e. the answer is correct or incorrect) in their analyses of students’ answers. Similarly, the majority of the participants recognized the type of mistake that the students made. However, they failed to successfully elaborate on fallacies, limitations, or strengths in student reasoning. We also asked the participants to make pedagogical decisions related to what needs to be done next in order to help the students to achieve academic objectives. Results show that 8% of the recommended instructional strategies were of no affordance, 64% of low-affordance, and 28% were of high affordance in terms of helping students achieve the academic objectives. Conclusion: If our goal is to improve pre-service science teachers’ noticing skills, and the affordance of feedback that they provide, engaging them in activities that asks them to attend to students’ ideas and reasoning may be useful.  相似文献

Research Findings: Anthropomorphism—the attribution of human characteristics to nonhuman entities—has long been a staple of children’s media. However, children’s experiences with anthropomorphic media may interfere with biological reasoning instead encouraging an anthropocentric view of the natural world. To date, little research has addressed the typical content of children’s storybooks about animals: Do these storybooks present factual information that may support early developing biological reasoning, or do they instead focus on human-centered, psychological information that may encourage anthropocentrism? We analyzed the types of causal explanatory information that commercial storybooks about animals provide to children about 2 biological concepts that have been extensively studied in the experimental literature: biological inheritance and the transmission of illness. Using coding schemes similar to those used in prior experimental literature to assess preschool-age children’s biological reasoning, we found that none of the anthropomorphized books presented children with scientifically accurate causal mechanisms. These books focused almost exclusively on social-emotional experiences as opposed to biological explanations, which may inadvertently encourage anthropocentric reasoning. Practice or Policy: Understanding more about the content of informal sources of early learning can help inform educators on how to best support developing knowledge about the natural world and biological properties.  相似文献

This paper aims at exploring (a) whether preschoolers recognize that offspring share physical traits with their parents due to birth and behavioural ones due to nurture, and (b) whether they seem ready to explain shared physical traits with a ‘pre-biological’ causal model that includes the contribution of both parents and a rudimentary notion of genes. This exploration is supposed to provide evidence for our next step, which is the development of an early years’ learning environment about inheritance. Conducting individual, semi-structured interviews with 90 preschoolers (age 4.5–5.5) of four public kindergartens in Patras, we attempted to trace their reasoning about (a) whether and why offspring share physical and behavioural traits with parents and (b) which mechanism could better explain the shared physical traits. The probes were a modified six-case version of Solomon et al. (Child Dev 67:151–171, 1996) ‘adoption task, as well as a three-case task based on Springer’s (Child Dev 66:547–558, 1995) ‘mechanism task’ and on Solomon and Johnson’s (Br J Dev Psychol 18(1):81–96, 2000) idea of genes as a ‘conceptual placeholder’. The qualitative and quantitative analysis of the interviews showed overlapping reasoning about the origin of physical and behavioural family resemblance. Nevertheless, we did trace the ‘birth-driven’ argument for the attribution of the offspring’s physical traits to the biological parents, as well as a preference for the ‘pre-biological’ model that introduces a rudimentary idea of genes in order to explain shared physical traits between parents and offspring. The findings of the study and the educational implications are thoroughly discussed.  相似文献

ABSTRACT

Context-based learning (CBL) is advocated as beneficial to learners, but more needs to be understood about how different contexts used in courses influence student outcomes. Gilbert defined several models of context that appear to be used in chemistry. In one model that achieves many criteria of student meaning-making, the context is provided by ‘personal mental activity’, meaning that students engage in a role to solve a problem. The model’s predicted outcomes are that students develop and use the specialised language of chemistry, translate what they learn in the immediate context to other contexts, and empathise with the community of practice that is created. The first two of these outcomes were investigated in two large-enrolment university chemistry courses, both organised as this CBL model, in which students were introduced to kinetic molecular theory (KMT). Sample 1 students (N1?=?105) learned KMT through whole-class kinaesthetic activity as a human model of a gas while focusing on a problem identifying substances in balloons filled with different gases. Sample 2 students (N2?=?110) manipulated molecular dynamics simulations while focusing on the problem of reducing atmospheric CO2. Exam answers and pre-/post-test responses, involving a new KMT context, were analysed. Students in Sample 1 demonstrated a stronger understanding of particle trajectories, while Sample 2 students developed more sophisticated mechanistic reasoning and greater fluidity of translation between contexts through increased use of chemists’ specialised language. The relationships of these outcomes to the contexts were examined in consideration of the different curriculum emphases inherent in the contexts.  相似文献

Abstract

This paper traces the evolution of early childhood care and education (ECCE) in Ireland over the course of the last century. Changing conceptualisations of the nature of childhood provide the context for understanding historical and contemporary approaches to ECCE. Historically, young children's care and education were treated as separate entities, with ‘care’ provided within the home and ‘education’ outside the home. However, the contemporary perspective recognises that young children's learning occurs on a continuum from birth, with care and education being interdependent. Although a distinct ECCE sector is beginning to emerge, prompted by developments at policy, practice and research level, there is considerable scope for further progress. Given ‘where we have come from’ and ‘where we are currently at’, future directions and recommendations for ECCE are elucidated.  相似文献
