This study was designed as a test for two neo-Piagetian theories. More specifically, this research examined the relationships between the development of proportional reasoning strategies and three cognitive variables from Pascual-Leone's and Case's neo-Piagetian theories. A priori hypotheses linked the number of problems students worked until they induced a proportional reasoning strategy to the variables of M-space, degree of field dependence, and short-term storage space. The subjects consisted of students enrolled in Physical Science I, a science course for nonscience majors at the University of Southern Mississippi. Of the 34 subjects in the study, 23 were classified as concrete operational on the basis of eight ratio tasks. Problems corresponding to five developmental levels of proportional reasoning (according to Piagetian and neo-Piagetian theory), were presented by a microcomputer to the 23 subjects who had been classified as concrete operational. After a maximum of 6 hours of treatment, 17 of the 23 subjects had induced ratio schemata at the upper formal level (IIIB), while the remaining subjects used lower formal level (IIIA) schemata. The data analyses showed that neither M-space and degree of field-dependence, either alone or in combination, nor short-term storage predicted the number of problems students need to do until they induce an appropriate problem-solving strategy. However, there were significant differences in the short-term storage space of those subjects who mastered ratio problems at the highest level and those who did not. Also, the subjects' degree of field-dependence was not a predictor of either the ability to transfer problem-solving strategies to a new setting or the reuse of inappropriate strategies. The results of this study also suggest that short-term storage space is a variable with high correlations to a number of aspects of learning such as transfer and choice of strategy after feedback. 相似文献

To test the hypothesis that the basic “logic” utilized by individuals in scientific hypothesis testing is the biconditional (if and only if), and that the biconditional is a precondition for the development of formal operations, a sample of 387 students in grades eight, ten, twelve, and college were administered eight reasoning items. Five of the items involved the formal operational schemata of probability, proportions and correlations. Two of the items involved propositions and correlations. Two of the items involved propositional logic. One item involved the biconditional. Percentages of correct responses on most of the items increased with age. A principal-component analysis revealed three factors, two of which were identified as involving operational thought, one of which involved propositional logic. As predicted, the biconditional reasoning item loaded on one of the operational thought factors. A Guttman scale analysis of the items failed to reveal a unidimensional scale, yet the biconditional reasoning item ordered first supporting the hypothesis that it is a precondition for formal operational reasoning. Implications for teaching science students how to test hypotheses are discussed. 相似文献

A review of the literature suggests a relationship between life-long development of formal reasoning schema and performance in professional education careers. The study investigated implications of cognitive development of preservice teachers as it relates to their classroom teaching performance. Ninety-one seniors involved in a field-oriented teacher education program were given classroom responsibilities which included teaching a science unit. Formal thinking abilities were assessed using two types of developmental level tasks, performance on traditional type Piagetian tasks and recognition of formal thought approaches in solving educational tasks. Professional behaviors were assessed using observational ratings of classroom instructional and planning activities. Subjects assessed as formal operational, 30% of sample, using Piagetian performance tasks, had significantly higher facility in performing model classroom teaching behaviors than transitional or concrete subjects. Higher recognition ability of formal thought approaches to teaching was not related to facility in performing classroom teaching when compared to performance on Piagetian tasks. The relationship held up in seven of eight broad teaching behavior categories observed in classroom instruction. The results supported a general portrait of teaching behavior specifically related to teachers of differing cognitive functional levels. Implications for professional training programs are discussed. 相似文献

Although the development of reasoning is recognized as an important goal of science instruction, its nature remains somewhat of a mystery. This article discusses two key questions: Does formal thought constitute a structured whole? And what role does propositional logic play in advanced reasoning? Aspects of a model of advanced reasoning are presented in which hypothesis generation and testing are viewed as central processes in intellectual development. It is argued that a number of important advanced reasoning schemata are linked by these processes and should be made a part of science instruction designed to improve students' reasoning abilities. Concerning students' development and use of formal reasoning, Linn (1982) calls for research into practical issues such as the roles of task-specific knowledge and individual differences in performance, roles not emphasized by Piaget in his theory and research. From a science teacher's point of view, this is good advice. Accordingly, this article will expand upon some of the issues raised by Linn in a discussion of the nature of advanced reasoning which attempts to reconcile the apparent contradiction between students' differential use of advanced reasoning schemata in varying contexts with the notion of a general stage of formal thought. Two key questions will be discussed: Does formal thought constitute a structured whole? And what role does propositional logic play in advanced reasoning? The underlying assumption of the present discussion is that, among other things, science instruction should concern itself with the improvement of students' reasoning abilities (cf. Arons, 1976; Arons & Karplus, 1976; Bady, 1979; Bauman, 1976; Educational Policies Commission, 1966; Herron, 1978; Karplus, 1979; Kohlberg & Mayer, 1972; Moshman & Thompson, 1981; Lawson, 1979; Levine & linn, 1977; Pallrand, 1977; Renner & Lawson, 1973; Sayre & Ball, 1975; Schneider & Renner, 1980; Wollman, 1978). The questions are of interest because to date they lack clear answers, yet clear answers are necessary if we hope to design effective instruction in reasoning. 相似文献

Piaget's structural theory of formal thought suggests that a general construct of formal reasoning exists. The content of the task and type of problem employed are often ignored in Piagetian based studies but are important for generalizing findings to other studies and to educational problems. The study reported here examines content and problem effects of formal thought in 13-year-old adolescents. Specifically, three controlling variables tasks with different content and two question type tests (analysis and controlling questions) were administered to 120 seventh graders. Ability measures and personality dimensions associated with formal reasoning in the literature are used to clarify what formal reasoning is and how content and problem type are involved in formal reasoning. Significant main effects were found for problem and content effects (p = 0.001), and a significant interaction was found between the two (p = 0.001). Across the three tasks general ability, field dependency, and locus of control were consistently and significantly related to the controlling questions. However, only measures of field dependency were related to the analysis questions. Combinations of ability and personality factors were found to be uniquely related to each task, within each question type. Results have implications for a theory of formal thought and the teaching of the controlling variables strategy. 相似文献

Lunzer reported data suggestive of a stage of cognitive development manifest between 9 and 11 years of age characterized by the ability to avoid drawing premature inferences when faced with ambiguity (i.e., accept lack of closure [ALC]). The present study sought to test this hypothesis. Inference tasks emphasizing ALC, memory, and hypothetico-deductive reasoning were administered to 67 males and 74 females (5-12 years in age). Although use of ALC increased with age, considerable use was evidenced on a simple task among 7-8-year-olds. On tasks hypothesized to place increasing demands on working memory, longer tasks were found to be more difficult. Marked improvement due to memory aids suggested that task difficulty results from limitations in working memory as predicted by Pascual-Leone's theory. Tasks requiring hypothetico-deductive reasoning were found to be most difficult. Performance was related to subject's spontaneous use of ALC. Lack of appropriate strategies was hypothesized to prevent solution rather than lack of logical competence. In conclusion, the relationship of ALC to age appears to be mediated by memory development rather than logical development. 相似文献

This study compared the relationships of self‐efficacy and reasoning ability to achievement in introductory college biology. Based on the hypothesis that developing formal and postformal reasoning ability is a primary factor influencing self‐efficacy, a significant positive correlation was predicted between reasoning ability and degree of self‐efficacy to complete biological tasks. Further, reasoning ability was predicted to be more highly correlated with course achievement than self‐efficacy. The study involved pre‐ and posttesting 459 introductory biology students. Both self‐efficacy and reasoning ability increased during the semester. As predicted, self‐efficacy and reasoning ability were positively correlated. Depending on the nature of the achievement measure, reasoning ability accounted for some 15 to 30 times more variance in achievement than self‐efficacy. Also, as predicted, reasoning ability was a strong predictor of self‐efficacy, but self‐efficacy was not a strong predictor of reasoning ability. Self‐efficacy estimates and achievement were higher for the concrete tasks than for the formal tasks and higher for the formal tasks than for the postformal tasks. In general, students tended to overestimate their abilities to carry out the concrete, formal, and postformal tasks. Results support the study's working hypothesis that intellectual development continues for some students during the college years, that a postformal level of intellectual development exists, and that reasoning ability is a primary factor influencing both self‐efficacy and achievement. Student overestimation of their abilities may contribute to complacency, lack of effort, and to less than optimal achievement. Consequently, it may be advantageous early in the semester to provide students with particularly challenging tasks that “shock” them out of their complacency and perhaps increase their effort, their reasoning skills, and their achievement. © 2006 Wiley Periodicals, Inc.

Performance in science reasoning tasks is a significant objective in modem science instruction and increasing emphasis is being placed on the development of higher cognitive processes in science education. An empirical analysis of the relationship between science reasoning skills and the amount of information acquired during science learning as predicted by a neuromathematical model of information processing is presented. As the neuromathematical model includes a variable representing verbal ability, it is to be expected that a direct relationship exists between the amount of knowledge gained as predicted by the model and reasoning ability. The purpose of this research is to derive a formal quantitative statement for the relationship between knowledge acquisition predicted by the neuromathematical equation and scientific reasoning skills. A linear regression equation is obtained relating performance on a science reasoning task to the amount of information acquired as predicted by the neuromathematical model. This research provides a first approximation to providing a theoretical and empirical link between information processing and higher cognitive thought processes in science education. 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

This study involved four age groups: 13–15-, 23–25-, 33–35-, and 43–45-yr-olds. All adult groups involved persons with university education and persons with low education. Participants (1) solved tasks addressed to spatial, propositional, and social reasoning, (2) evaluated their own performance and the difficulty of the tasks, and (3) answered an inventory probing their self-concept for these reasoning domains and for self-awareness and self-regulation. Structural modeling revealed that performance, self-evaluation, and self-representation are systematically interrelated. Performance in spatial and propositional reasoning stabilized in early adulthood, whereas in social reasoning and self-evaluation, performance improved throughout the age span studied. Educated persons performed better and rated themselves accordingly across all domains. The implications of these findings for the general theory of intelligence and cognitive development after adolescence are discussed. The functional shift model is proposed to account for changes in the relative power of different abilities with increasing age. 相似文献

To test the hypothesis that cultural diversity contributes to the development of formal reasoning, samples of adolescents from three predominately white middle-class communities located in areas that varied in the extent to which they offered cultural diversity (i.e., rural, suburan homogeneous, suburban heterogeneous) were administered a test of formal reasoning and a test of analytical intelligence. Results showed significant differences in formal reasoning in favor of the suburban heterogeneous sample on complex reasoning items. The suburban groups showed equal performance (but superior to the rural Ss) on the test of analytical intelligence. On the less complex reasoning items and on one item embedded in a rural farming context, the rural Ss showed relatively better performance. Implications for using science instruction to promote formal reasoning are discussed. 相似文献

The purpose of this study was to investigate the relationships among gender, age, and intellectual development. Random samples of 70 females and 70 males were selected with each sex group equally divided into a low-age and a high-age group. The low-age group ranged in age from 16.25 years to 16.75 years and the high-age group from 16.76 years to 17.25 years. The Piaget tasks selected to measure cognitive development were: Conservation of Volume, Separation of Variables, and Equilibrium in the Balance and Combination of Colorless Chemical Liquids. Data from this research produced these findings: (1) males demonstrate a higher level of intellectual development than females, (2) males mature intellectually earlier than females, (3) the value of the conservation of volume task as a component of a battery of formal tasks depends upon whether the decisions are to be made on the basis of the total-task results or on individual task performance, and (4) there appear to be factors other than age and gender that are related to the development of formal operational reasoning. These investigators hypothesize that experiences is another important factor. 相似文献

The hypothesis is advanced that a necessary, though not sufficient, condition for the acquisition of proportional reasoning during adolescence is the prior internalization of key linguistic elements of argumentation, essentially those used in hypothetico-deductive reasoning. This hypothesized internalization, which does not occur in all individuals, results in some who have acquired the ability to reflect upon the correctness of self-generated answers in a hypothetico-deductive manner, and others who have not. As an initial test of the hypothesis, 46 subjects (Ss) (mean age = 21.03 years) were classified into additive, transitional, or proportional reasoning categories based upon responses to a proportions task. Group differences were found in which proportional Ss performed better than transitional Ss who in turn performed better than additive Ss on a number of items testing Ss' abilities to identify, generate, and use the linguistic elements of argumentation. Further it was found that some Ss who were successful on the linguistic items failed the proportions task, but no Ss who were successful on the proportions task failed the linguistic items. This result supports the hypothesis that the internalization of linguistic elements of argumentation is a prerequisite for proportional reasoning and by inference other advanced reasoning schemata as well. Implications for science instruction are drawn. 相似文献

Two selection hypothesis testing tasks and nine evaluation hypothesis testing tasks which varied systematically with respect to causality, response alternatives, and context continuity were administered to two samples of adults to determine the effects of those variables and to determine the degree to which subjects (Ss) reasoned with material conditional, material biconditional, partial, or partial plus biconditional connectives. On the causal selection task the majority of Ss responded “yes” to all four instances, while on the evaluation tasks all three variables were found to affect performance. Ss responded consistently with the material biconditional connective especially when the tasks called for them to state their expectations or were written with context continuity. Results were interpreted to support the hypothesis that hypothesis testing reasoning in causal contexts begins with the material biconditional connective and involves schemata of controlling variables, probability, and correlations. A strictly “logical” falsification strategy is not viewed as operative. Implications for teaching students how to effectively test hypotheses in science classes are discussed. 相似文献

Evidence from the research literature suggests that a variety of cognitive factors is responsible for chemistry achievement. This investigation examined the role of four cognitive factors, namely, formal reasoning ability, prior knowledge, field dependence/ independence, and memory capacity on achievement in chemistry as measured by tests of laboratory application, chemical calculations and content knowledge. The sample comprised grade 11 students from eleven high schools who were following the same chemistry syllabus. The results indicated that prior knowledge and formal reasoning ability were each statistically significantly related to variation in chemistry achievement. Field dependence/independence and memory capacity played no significant role in chemistry achievement. 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

This paper presents an investigation into the development of functional thinking. Search strategies used for solving a problem reveal different stages towards the discovery of the monotonic property, which correspond to stages of proportional reasoning found by Piaget. The dependence between stage and age is confirmed by the results. 相似文献

Measurements of formal reasoning and principled moral reasoning ability were obtained from a sample of 99 tenth grade students. Specific modes of formal reasoning (proportional reasoning, controlling variables, probabilistic, correlational, and combinatorial reasoning) were first examined. Findings support the notion of hierarchical relationships which exist among those variables. Further results from factor analysis provide evidence that the variables represent specific cognitive structures that are interdependent with each other and precede operations in development. Finally, significant relationships were found to exist between the different modes of formal reasoning and principled moral reasoning. Combinatorial and correlational reasoning were found to significantly account for 22% of the variance in principled moral reasoning. Theoretical and educational implications are discussed. 相似文献
