The purpose of this study was to extend previous research on the conditions that may promote understanding and abstraction via structural alignment, that is, through a comparison between two partially understood situations. Structural alignment is a route to analogical reasoning which differs from the typical route where an analogy is made by eliciting an unknown situation from a very familiar one. Ninety-nine eighth graders were presented with two pairs of scenarios; the first depicting two phenomena of heat flow and the second, two phenomena of the changing state of matter. Participants were randomly assigned to five different conditions which varied in the degree to which they required a comparisonbetween the phenomena in the scenario pairs. For each pair of scenarios, participants were asked to describe the differences between the two phenomena, explain what happens in the phenomena, rate the similarity between the two, and justify the ratings. Results show that analogical reasoning was promoted more in the condition where participants were asked to jointly interpret the phenomena depicted in the scenarios. For both pairs of scenarios, students in this condition reached a deeper understanding; they were more able to identify alignable differences between the phenomena, and recognize the abstract and general higher-order relational structure implied by the perceptually different situations.  相似文献

Relational reasoning, a higher-order cognitive ability that identifies meaningful patterns among information streams, has been suggested to underlie STEM development. This study attempted to explore the potentially unique contributions of four forms of relational reasoning (i.e., analogy, anomaly, antinomy, and antithesis) to mathematical problem solving. Two separate samples, fifth graders (n = 254) and ninth graders (n = 198), were assessed on their mathematical problem solving ability and the different forms of relational reasoning ability. Linear regression analysis was conducted, with participants’ age, working memory, and spatial skills as covariates. The results showed that analogical and antithetical reasoning abilities uniquely predicted mathematical problem solving. This pattern demonstrated developmental stability across a four-year time frame. The findings clarify the unique significance of individual forms of relational reasoning to mathematical problem solving and call for a shift of research direction to reasoning abilities when exploring dissimilarity-based relations (opposites in particular).  相似文献

Abstract reasoning is critical for science and mathematics, but is very difficult. In 3 studies, the hypothesis that alternatives generation required for conditional reasoning with false premises facilitates abstract reasoning is examined. Study 1 (n = 372) found that reasoning with false premises improved abstract reasoning in 12- to 15-year-olds. Study 2 (n = 366) found a positive effect of simply generating alternatives, but only in 19-year-olds. Study 3 (n = 92) found that 9- to 11-year-olds were able to respond logically with false premises, whereas no such ability was observed in 6- to 7-year-olds. Reasoning with false premises was found to improve reasoning with semiabstract premises in the older children. These results support the idea that alternatives generation with false premises facilitates abstract reasoning.  相似文献

Working memory is related to children’s ability to solve analogies and other inductive reasoning tasks. The aim of this study was to examine whether working memory also plays a role in training and transfer effects of inductive reasoning in the context of a short training procedure within a pretest-training-posttest-transfer design. Participants were 64 children, aged 7–8 years (M = 7.6 years; SD = 4.7 months). All of the children were pre-tested on inductive reasoning and working memory tasks. The children were trained in figural analogy solving according to either the graduated prompts method or practice without feedback. The children were then post-tested on the trained task and three additional inductive reasoning measures. Regression models revealed that visuo-spatial working memory was related to initial performance on each of the inductive reasoning tasks (r  .35). Children’s improvement from pretest to posttest in figural analogy solving, as measured with item response theory models, was somewhat related to visuo-spatial WM but not verbal WM scores or pretest scores. Furthermore, transfer of reasoning skills to an analogy construction task was related to initial ability, but not working memory; transfer to two inductive reasoning tasks with dissimilar content was not apparent. Performance change and ability to transfer trained skills to new tasks are not often used in psycho-educational assessment but may be separate constructs indicative of children’s learning and change.  相似文献

The relationship between general knowledge (GK) and cognitive ability (IQ and abstract reasoning), learning approaches, and personality (‘big five’ traits and typical intellectual engagement) was investigated in a sample of 101 British undergraduates. As predicted, GK was positively correlated with cognitive ability (more so with IQ than with abstract reasoning), typical intellectual engagement, and openness to experience. A hierarchical regression showed that IQ was the strongest predictor of GK, explaining 26% of GK variance. However, openness (15%) added incremental validity to the variance explained. These results are discussed in relation to previous findings in the field of GK and the personality–intelligence interface.  相似文献

One of the “classical” ways of learning consists of studying examples of already solved problems. In two experiments, we analyzed the degree of abstraction of the knowledge used by ninth grade students to solve algebra problems after studying worked examples. The results showed that there are two processes underlying reasoning by analogy, one that uses abstract knowledge and another that involves case-based reasoning. Both experiments pointed out interindividual differences in the population under study: when given examples, some subjects seem to extract the structure of the solving process by comparing the worked examples, while others focus more on the specifics of each example. To these two processes correspond two levels of transfer: correctly solve problems that have the same structure as the examples, regardless of how similar they are, or be better at solving problems that resemble the examples the most. Experiment 2 used a dual-task paradigm to show that some subjects implement both processes, in which case the mental load is greater. This experiment also showed that both processes can lead to the long-term acquisition of the principles behind the examples.  相似文献

Students in a large one-semester nonmajors college biology course were classified into one of three groups (intuitive—I, transitional—T, reflective—R) based upon a pretest of scientific reasoning ability. Laboratory teams of two students each then were formed, such that all possible combinations of reasoning abilities were represented (i.e., I-I, I-T, I-R, T-T, T-R, R-R). Students worked with their assigned partners during each of the course's 14 laboratory sessions. Gains in reasoning ability, laboratory achievement, and course achievement, as well as changes in students' opinions of their motivation, enjoyment of the laboratory, and their own and their partner's reasoning abilities were assessed at the end of the semester. Significant pre- to posttest gains in reasoning ability by the intuitive and transitional students were found, but these gains were not significantly related to the laboratory partner's reasoning ability. Also, course achievement was not significantly related to the laboratory partner's reasoning ability. Students were perceptive of others' reasoning ability; the more able reasoners were generally viewed as being more motivated, having better ideas, and being better at doing science. Additional results also indicated that course enjoyment and motivation was significantly decreased for the transitional students when they were paired with intuitive students. Apparently, for students in transition (i.e., not at an equilibrium state with regard to reasoning level), it is frustrating to work with a less able reasoner. However, some evidence was found to suggest that reflective students may benefit from working with a less able partner.  相似文献

This study examined differences in transfer of analogical reasoning after analogy-problem solving between 40 gifted and 95 average-ability children (aged 9–10 years old), utilising dynamic testing principles. This approach was used in order to examine potential differences between gifted and average-ability children in relation to progression after training, and with regard to the question whether training children in analogy problem-solving elicits transfer of analogical reasoning skills to an analogy construction-task. Children were allocated to one of two experimental conditions: either children received unguided practice in analogy problem-solving, or they were provided with this in addition to training incorporating graduated prompting techniques. The results showed that gifted and average-ability children who were trained made more progress in analogy problem-solving than their peers who received unguided practice experiences only. Gifted and average-ability children were found to show similar progression in analogy problem-solving, and gifted children did not appear to have an advantage in the analogy-construction transfer task. The dynamic training seemed to bring about no additional improvement on the transfer task over that of unguided practice experiences only.  相似文献

This study examined test-related experiences of enjoyment, anger, anxiety, and boredom in a sample of 2059 German school students (50% female) from grade 6, and how they relate to students' abstract reasoning ability (ARA). Emotions were assessed immediately before, during, and after a mathematics achievement test. Analysis of variance showed that emotions experienced during the test situation differed based on students' ARA level, with correspondence analysis revealing substantial differences between the emotional profiles of different ability groups. Enjoyment proved to be most prominent in students with high ARA, whereas anger and anxiety were predominant for students with low ARA. Boredom was found to be highest among students in the intermediate ARA group. Implications for research and practice are discussed.  相似文献

This qualitative study aimed at exploring whether students’ successful use of analogy in learning curriculum complex science concepts was related: (a) to the level of their understanding of a specific analogy and (b) to their metacognitive awareness of how the analogy was to be used and of the changes produced in their own conceptual structures. In implementing a biological curriculum unit, students’ prior knowledge has been taken into account in order to examine its conceptual growth and change via a not completely introduced analogy to 15 fifth graders as they were engaged in understanding the ways in which the new concepts (on photosynthesis) were similar to a familiar source (making a cake). Qualitative data present the children's mapping processes in elaborating the analogy and their metacognitive awareness of the meaning and purpose of the analogy itself, and their personal use of the analogy in changing initial conceptions. As hypothesised, the results showed a high positive correlation among the level of conceptual understanding of the new science topic, the level of understanding of the analogy, and the level of effective use of the analogy in integrating the new information into the pre‐existing conceptual structures. Key implications on the use of analogy for conceptual change in the classroom are outlined.  相似文献

Analogical reasoning is believed to be an efficient means of problem solving and construction of knowledge during the search for and the analysis of new mathematical objects. However, there is growing concern that despite everyday usage, learners are unable to transfer analogical reasoning to learning situations. This study aims at facilitating analogy use for conjecturing in discourse-rich mathematics classrooms. We reconceptualized one of the traditional perspectives on analogical reasoning, called classical analogy, as a more dynamic one by providing learners with the opportunity to choose a target object and its property. While shifting attention to particular aspects of mathematical activity, we observed and analyzed how students became aware of hidden relational similarities and utilized them while weakening others to make conjectures. The detailed analysis of the constructs and processes of several similarity-making and conjecturing activities supports the significance of reconceived classical analogy use in mathematics classrooms.  相似文献

An instrument was developed to assess the logical reasoning capacity of adolescents in the content area of environmental science. Characterized as a group test, the instrument consisted of five concrete experiences related to environmental concepts, to which pencil-and-paper responses were made. The instrument was validated through (1) logical analysis of items from the standpoint of Piagetian theory, (2) correlation with clinical interviews and group test results in physical science, and (3) factor analysis. The results indicated an acceptable level of validity for the instrument in each category. Concurrently, the results of the study indicated that the reasoning level of the subjects was well below the theoretical levels predicted for them by theory. The results also suggested that reasoning ability in environmental science was lower than in areas associated with the physical concepts usually tested. The data suggested the presence of a horizontal decalage, or time lag, between the development of logical reasoning skills in areas of familiarity, such as physical science, and areas of content less familiar to the subject or those in which logical structures may be less frequently used in the development of evaluation instruments.  相似文献
