Inquiry learning environments increasingly incorporate modelling facilities for students to articulate their research hypotheses and (acquired) domain knowledge. This study compared performance success and scientific reasoning of university students with high prior knowledge (n = 11), students from senior high‐school (n = 10), and junior high‐school (n = 10) with intermediate and low prior knowledge, respectively, in order to reveal domain novices’ need for support in such environments. Results indicated that the scientific reasoning of both groups of high‐school students was comparable to that of the experts. As high‐school students achieved significantly lower performance success scores, their expert‐like behaviour was rather ineffective; qualitative analyses substantiated this conclusion. Based on these findings, implications for supporting domain novices in inquiry learning environments are advanced.  相似文献

Due to the complexity of the legal domain, reasoning about law cases is a very complex skill. For novices in law school, legal reasoning is even more complex because they have not yet acquired the conceptual knowledge needed for distilling the relevant information from cases, determining applicable rules, and searching for rules and exceptions in external information sources such as lawbooks. This study investigated the role of conceptual knowledge in solving legal cases when no information sources can be used. Under such ‘unsupported’ circumstances, novice and advanced students performed less well than domain experts, but even experts’ performance was rather low. The second question addressed was whether novices even benefit from the availability of information sources (i.e., lawbook), because conceptual knowledge is prerequisite for effective use of such sources. Indeed availability of the lawbook positively affected performance only for advanced students but not for novice students. Implications for learning and instruction in the domain of law are discussed.  相似文献

ABSTRACT

Many science curricula and standards emphasise that students should learn both scientific knowledge and the skills associated with the construction of this knowledge. One way to achieve this goal is to use inquiry-learning activities that embed the use of science process skills. We investigated the influence of scientific reasoning skills (i.e. conceptual and procedural knowledge of the control-of-variables strategy) on students’ conceptual learning gains in physics during an inquiry-learning activity. Eighth graders (n?=?189) answered research questions about variables that influence the force of electromagnets and the brightness of light bulbs by designing, running, and interpreting experiments. We measured knowledge of electricity and electromagnets, scientific reasoning skills, and cognitive skills (analogical reasoning and reading ability). Using structural equation modelling we found no direct effects of cognitive skills on students’ content knowledge learning gains; however, there were direct effects of scientific reasoning skills on content knowledge learning gains. Our results show that cognitive skills are not sufficient; students require specific scientific reasoning skills to learn science content from inquiry activities. Furthermore, our findings illustrate that what students learn during guided inquiry activities becomes visible when we examine both the skills used during inquiry learning and the process of knowledge construction. The implications of these findings for science teaching and research are discussed.  相似文献

This paper focuses on the transformation of general metacognitive skills of novices into domain-specific regulatory procedures of experts, and the relation of those skills to intelligence. Research has shown that the general metacognitive skills of novices, although partly correlated to intelligence, additionally contribute to learning outcome on top of intelligence. The metacognitive skills of experts appear to be domainspecific and unrelated to intelligence. Two experiments were conducted. The objective of the first experiment was to confirm and generalize these earlier results concerning the relation of intellectual ability, metacognitive skillfulness and learning of novices vs. advanced subjects. The objective of the second experiment was to investigate this relation under different conditions of task complexity. It was hypothesized that advanced subjects would regress to more novice-like behavior under very complex learning conditions (i.e., general metacognitive skills and intelligence would re-appear as combined predictors of learning outcome). On the other hand, low intelligent novices, irrespective of their metacognitive skillfulnes, were expected to fail on very complex problems. Results partly confirmed these hypotheses. Implications for the conditions under which metacognitive experiences should be implemented, are being discussed.  相似文献

The literature on the role of models and theories in physics suggests that multiple models, abstract or concrete exist for a particular phenomenon. These models could be organized into hierarchies describing the entire physics domain (Giere 1994). Hierarchies of concepts have been used in other domains with success; however, criteria for a hierarchy of models in physics and theory's role are unclear. Therefore, research was conducted to describe the knowledge structures of experts, intermediates, and novices. A reiterative categorization task required subjects to sort and re-sort physics problems. The proportions of theory- and model-based categories created by the subjects were compared. Novices created hierarchies of model-based categories. Both intermediates and experts created theory-based categories at the highest, most abstract, level but combined model- and theory-based categories at middle and lower levels. These results support a representation of physics knowledge in which a hierarchy of models is organized by theory-based categories.  相似文献

The purpose of this study is to investigate how sixth graders develop inquiry skills to construct explanations in an inquiry‐based learning environment. We designed a series of inquiry‐based learning activities and identified four inquiry skills that are relevant to students’ construction of explanation. These skills include skills to identify causal relationships, to describe the reasoning process, to use data as evidence, and to evaluate explanations. Multiple sources of data (e.g., video recordings of learning activities, interviews, students’ artifacts, and pre/post tests) were collected from two science classes with 58 sixth graders. The statistical results show that overall the students’ inquiry skills were significantly improved after they participated in the series of the learning activities. Yet the level of competency in these skills varied. While students made significant progress in identifying causal relationships, describing the reasoning process, and using data as evidence, they showed slight improvement in evaluating explanations. Additionally, the analyses suggest that phases of inquiry provide different kinds of learning opportunities and interact with students’ development of inquiry skills.  相似文献

The purpose of this study was to describe the problem-solving behaviors of experts and novices engaged in solving seven chemical equilibrium problems. Thirteen novices (five high-school students, five undergraduate majors, and three nonmajors) and ten experts (six doctoral students and four faculty members) were videotaped as they individually solved standard chemical equilibrium problems. The nature of the problems was such that they required more than mere recall or algorithmic learning and yet simple enough to provide the novices a reasonable chance of solving them. Extensive analysis of the think-aloud protocols produced 27 behavioral tendencies that can be used to describe and differentiate between successful and unsuccessful problem solvers. Successful solvers' perceptions of the problem were characterized by careful analysis and reasoning of the task, use of related principles and concepts to justify their answers, frequent checks of the consistency of answers and reasons, and better quality of procedural and strategic knowledge. Unsuccessful subjects had many knowledge gaps and misconceptions about the nature of chemical equilibrium. Even faculty experts were sometimes unable to correctly apply common chemical principles during the problem-solving process. Important theoretical concepts such as molar enthalpy, heat of reaction, free energy of formation, and free energy of reaction were rarely used by novices in explaining problems.  相似文献

Spatial ability has been found to be a good predictor of success in learning anatomy. However, little research has explored whether spatial ability can be improved through anatomy education and experience. This study had two aims: (1) to determine if spatial ability is a learned or inherent facet in learning anatomy and (2) to ascertain if there is any difference in spatial ability between experts and novices in anatomy. Fifty participants were identified: 10 controls, 10 novices, 10 intermediates, and 20 experts. Participants completed four computerized spatial ability tasks, a visual mental rotation task, categorical spatial judgment task, metric spatial task, and an image-scanning task. The findings revealed that experts (P = 0.007) and intermediates (P = 0.016) were better in the metric spatial task than novices in terms of making more correct spatial judgments. Experts (P = 0.033), intermediates (P = 0.003), and novices (P = 0.004) were better in the categorical spatial task than controls in terms of speed of responses. These results suggest that certain spatial cognitive abilities are especially important and characteristic of work needed in clinical anatomy, and that education and experience contribute to further development of these abilities.  相似文献

This exploratory study investigates the distributed nature and complexity of professional expertise by examining the patterns of cognitive processes in novices and experts who are using ultrasound technology to make diagnoses. The study aims to identify and provide an explanation for such patterns in light of the recent debate on the locus of control underpinning human cognition. A distributed model of professional expertise based on the relationships between the four elements of socio-cultural disposition, tools and artefacts, strategies, and domain knowledge, is used to discuss the results. The findings illustrate the complexity of professional expertise, particularly when individuals depend on sophisticated tools to assist their thinking and reasoning.  相似文献

Previous research on the role of prior skills like proportional reasoning skills for the development of mathematical concepts offers conclusions such as “more (prior skills) is better (for later learning).” Insights, which prior skill level goes along with which level of learning outcomes, may advance the understanding of the development of mathematical concepts. An exploratory approach is presented based on level models to describe the relation between symbolic proportional reasoning skills and fraction outcomes beyond linearity. Analyses draw on samples of German fourth to sixth graders from a scaling (2017, N = 325, 54.8% female) and longitudinal study (2018/2019, N = 436, 42.7% female). Particularly mastering natural and internal rational ratios in proportional reasoning seems relevant for successful fraction learning.  相似文献

In an earlier study we found that intermediate experts in the domain of economics did not surpass novices in complex learning and knowledge application with a computer-based business simulation. In the present study, it was investigated whether these contra-intuitive findings can be replicated. In order to scrutinize the reasons which led to these findings, some parameters of the learning environment were changed. The duration of the exploration phase and of the problem-solving phase as well as the complexity of the situations were increased, motivation and acquired declarative knowledge were assessed. In view of mastering recurring demands and the functionality of mental models, no differences were found between a group of novices (15 students of humanities with a supplementary training in economics) and a group of intermediate experts (13 advanced students of economics). The findings of the original study were replicated, motivation had no effect on the result. In terms of declarative knowledge, the novices turned out to be even better.  相似文献

Scientific reasoning skills can be acquired through technology-enhanced inquiry tasks or video modeling examples showing how to conduct virtual experiments. However, inquiry tasks can be cognitively demanding for novice learners, whereas video modeling examples can induce overconfidence. The present study investigated the effectiveness of both approaches in isolation and combination. We compared the effects of four groups (example-example, example-task, task-example and task-task) on learning outcomes, perceived difficulty and mental effort, judgments of learning, and monitoring accuracy among 107 seventh graders. In line with our hypotheses, watching a video modeling example first led to lower mental effort, better learning outcomes, and higher judgments of learning than solving an inquiry task first. Contrary to our hypotheses, all groups underestimated their performance. Results for mental effort and learning outcomes corroborate research on worked examples, whereas results for judgments of learning and monitoring accuracy indicate an underconfidence-with-practice effect.  相似文献

Recently, cognitive load theory has been considered within conceptual change research. Although the effectiveness of refutation texts (RT) has been proven, the conceptual change process involved and the influencing factors remain unclear. To contribute to this research, we investigate the efficiency of pupils working with a modified RT design in which the alternative and scientific conceptions are not explicitly contrasted, and we examine the level of learner expertise as a possible influencing factor. We investigated the efficiency based on the scientific conceptions learned and the mental effort invested (reflecting cognitive load) during instruction (N = 195, 9th graders). Only pupils with high prior knowledge (experts) showed low efficiency and higher mental effort when dealing with alternative conceptions. Our results indicate that the experts did not profit from the mental effort they invested in the learning process, whereas the novices seemed to profit from their invested mental effort.  相似文献

This article examines the learning of different types of graphic information by subjects with different levels of education and knowledge of the content represented. Three levels of graphic information learning were distinguished (explicit, implicit, and conceptual information processing) and two experiments were conducted, looking at graph and geographical map learning. The graph study (Experiment 1) examined the influence of the variables' numerical relationship structure on adolescent students with different levels of education and knowledge of social sciences and also assessed their proportional reasoning skills. The map study (Experiment 2) looked at the learning of a geographical map studied spontaneously by secondary school and university students with different geographical knowledge (experts and novices) and also assessed their spatial skills. The results of both studies show that graph and map learning performance improves with the subjects' educational level. The groups' differential performance varied according to the type of information involved (explicit, implicit, or conceptual). The subjects' knowledge of the domain in question determined the level at which they processed the information. Verbal and superficial processing of graphic information were also found to predominate. This has important educational implications, suggesting the need for differential treatment in teaching different types of information. The results of the study also raise interesting issues regarding the type of expertise involved in learning graphic information: expertise related to the content represented, to knowledge of the syntax (graphicacy), and/or the system of knowledge graphically represented – spatial in the case of maps, numerical in the case of graphs.  相似文献

The purposes of the present study were (a) to compare US and Korean 8th graders' mastery of knowledge and skills in the mathematics test of the Trends in International Mathematics and Science Study (TIMSS) 2003 using a cognitive diagnostic testing method and (b) to find links between teachers' instruction and students' mastery of mathematics knowledge and skills. The participants included 740 US and 439 Korean 8th graders who took the Booklet 3 mathematics test. The results showed substantial differences between the US and Korean students' performance in problem restructuring and reasoning, measurement, and geometry. The most helpful instructional strategy for both Korean and US students was encouraging students' independent problem solving. Reviewing, re-teaching, and clarifying content were especially effective for the US students. Implications for teaching and learning are discussed.  相似文献

Many studies have previously focused on how people with different levels of expertise solve physics problems. In early work, focus was on characterising differences between experts and novices and a key finding was the central role that propositionally expressed principles and laws play in expert, but not novice, problem-solving. A more recent line of research has focused on characterising continuity between experts and novices at the level of non-propositional knowledge structures and processes such as image-schemas, imagistic simulation and analogical reasoning. This study contributes to an emerging literature addressing the coordination of both propositional and non-propositional knowledge structures and processes in the development of expertise. Specifically, in this paper, we compare problem-solving across two levels of expertise—undergraduate students of chemistry and Ph.D. students in physical chemistry—identifying differences in how conceptual metaphors (CMs) are used (or not) to coordinate propositional and non-propositional knowledge structures in the context of solving problems on entropy. It is hypothesised that the acquisition of expertise involves learning to coordinate the use of CMs to interpret propositional (linguistic and mathematical) knowledge and apply it to specific problem situations. Moreover, we suggest that with increasing expertise, the use of CMs involves a greater degree of subjective engagement with physical entities and processes. Implications for research on learning and instructional practice are discussed.  相似文献

The primary goal of this study was the broad assessment and modeling of scientific reasoning in elementary school age. One hundred fifty-five fourth graders were tested on 20 recently developed paper-and-pencil items tapping four different components of scientific reasoning (understanding the nature of science, understanding theories, designing experiments, and interpreting data). As confirmed by Rasch analyses, the scientific reasoning items formed a reliable scale. Model comparisons differentiated scientific reasoning as a separate construct from measures of intelligence and reading skills and revealed discriminant validity. Furthermore, we explored the relationship between scientific reasoning and the postulated prerequisites inhibitory control, spatial abilities and problem-solving skills. As shown by correlation and regression analyses, beside general cognitive abilities (intelligence, reading skills) problem-solving skills and spatial abilities predicted performance in scientific reasoning items and thus contributed to explaining individual differences in elementary school children's scientific reasoning competencies.  相似文献

Understanding and using symbolic fractions in mathematics is critical for access to advanced STEM concepts. However, children and adults consistently struggle with fractions. Here, we take a novel perspective on symbolic fractions, considering them within the framework of relational structures in cognitive psychology, such as those studied in analogy research. We tested the hypothesis that relational reasoning ability is important for reasoning about fractions by examining the relation between scores on a domain-general test of relational reasoning (TORR Jr.) and a test of fraction knowledge consisting of various types of fraction problems in 194 s grade and 145 fifth grade students. We found that relational reasoning was a significant predictor of fractions knowledge, even when controlling for non-verbal IQ and fractions magnitude processing for both grades. The effects of relational reasoning also remained significant when controlling for overall mathematics knowledge and skill for second graders but was attenuated for fifth graders. These findings suggest that this important subdomain of mathematical cognition is integrally tied to relational reasoning and opens the possibility that instruction targeting relational reasoning may prove to be a viable avenue for improving children’s fractions skills.  相似文献
