Grammatical knowledge is an important part of L1 language education. Nevertheless, teachers find it challenging to convey an in-depth understanding of grammar to their students. Previous research suggests that understanding might be stimulated by focusing on grammatical reasoning. The current mixed-methods study explores the grammatical reasoning of 108 Dutch L1 student teachers’ in odd one out tasks, showing that student teachers struggle with such reasoning tasks. A multilevel regression analysis indicates that their level of grammatical understanding as measured by a Test of Grammatical Understanding (TGU) and the elaborateness of student teachers’ argumentation significantly predict the quality of their grammatical reasoning. Student teachers’ performances were also compared to 14 year old pre-university students’ performances (N = 120). Contrary to what was hypothesized, senior student teachers did not manage to outperform junior student teachers, nor did student teachers outperform pre-university students. The paper discusses plausible reasons for these findings and explores how teacher education might need to shift focus to better develop student teachers’ grammatical reasoning skills.  相似文献

What strategies do high school students use when solving chemistry problems? The purpose for conducting this study was to determine the general problem-solving skills that students use in solving problems involving moles, stoichiometry, the gas laws, and molarity. The strategies were examined for success in problem solving for 266 students of varying proportional reasoning ability, using interviews incorporating the think-aloud technique. Data were coded using a scheme based on Polya's heuristics. Results indicated that successful students and those with high proportional reasoning ability tended to use algorithmic reasoning strategies more frequently than nonsuccessful and low proportional reasoning students. However, the majority of all students solved the chemistry problems using only algorithmic methods, and did not understand the chemical concepts on which the problems were based.  相似文献

Problem solving abilities are critical components of contemporary Science, Technology, Engineering and Mathematics (STEM) education. Research in the area of problem solving has uncovered much about the representation, processes and heuristic approaches to problem solving. However, critics claim this overemphasis on the process of solving problems has led to a dearth in understanding of the earlier stages such as problem conceptualization. This paper aims to address some of these concerns by exploring the area of problem conceptualization and the underlying cognitive mechanisms that may play a supporting role in reasoning success. Participants (N?=?12) were prescribed a series of convergent problem-solving tasks representative of those used for developmental purposes in STEM education. During the problem-solving episodes, cognitive data were gathered by means of an electroencephalographic headset and used to investigate students’ cognitive approaches to conceptualizing the tasks. In addition, interpretive qualitative data in the form of post-task interviews and problem solutions were collected and analyzed. Overall findings indicated a significant reliance on memory during the conceptualization of the convergent problem-solving tasks. In addition, visuospatial cognitive processes were found to support the conceptualization of convergent problem-solving tasks. Visuospatial cognitive processes facilitated students during the conceptualization of convergent problems by allowing access to differential semantic content in long-term memory.

Situating the conceptual knowledge of a science discipline in the context of its use in the solving of problems allows students the opportunity to develop: a highly structured and functional understanding of the conceptual structure of the discipline; general and discipline-specific problem-solving strategies and heuristics; and insight into the nature of science as an intellectual activity. In order realize these potential learning outcomes, the reconstructions of scientific theories used in problem solving must provide a detailed account of (1) realistic scientific problems and their solutions; (2) problem-solving strategies and patterns of reasoning of disciplinary experts; (3) the various ways that theories function for both disciplinary experts and students; and (4) the way theories, as solutions to realistic scientific problems, develop over time. The purpose of this paper, therefore, is to provide further specificity regarding a philosophical reconstruction of the structure of Classical Genetics Theory that can facilitate problem-solving instruction. We analyze syntactic, semantic and problem-based accounts of theory structure with respect to the above criteria and develop a reconstruction that incorporates elements from the latter two. We then describe how that reconstruction can facilitate realistic problem solving on the part of students.  相似文献

Researchers have pointed out the difficulties that high school students have in understanding meiosis and the infrequency with which they acknowledge the conceptual relationships between meiosis and classical genetics, particularly when solving genetics problems. The research described in this article paints a different picture of students' reasoning with meiosis as they solved complex, computergenerated genetics problems, some of which required them to revise their understanding of meiosis in response to anomalous data. Details are presented of the ways students used their knowledge of meiosis to recognize anomalous data, to generate hypotheses as part of the revision of explanatory models, and to assess these hypotheses. The findings from this research, contrary to most reports in the literature, suggest that students are able to develop rich understanding of meiosis and can utilize that knowledge to solve genetics problems.  相似文献

A growing body of research has examined the experiential grounding of scientific thought and the role of experiential intuitive knowledge in science learning. Meanwhile, research in cognitive linguistics has identified many conceptual metaphors (CMs), metaphorical mappings between abstract concepts and experiential source domains, implicit in everyday and scientific language. However, the contributions of CMs to scientific understanding and reasoning are still not clear. This study explores the roles that CMs play in scientific problem-solving through a detailed analysis of two physical chemistry PhD students solving problems on entropy. We report evidence in support of three claims: a range of CMs are used in problem-solving enabling flexible, experiential construals of abstract scientific concepts; CMs are coordinated with one another and other resources supporting the alignment of qualitative and quantitative reasoning; use of CMs grounds abstract reasoning in a “narrative” discourse incorporating conceptions of paths, agents, and movement. We conclude that CMs should be added to the set of intuitive resources others have suggested contribute to expertise in science. This proposal is consistent with two assumptions: that cognition is embodied and that internal cognitive structures and processes interact with semiotic systems. The implications of the findings for learning and instruction are discussed.  相似文献

Problem-solving skills and understanding of domain, knowledge (e.g., fighting misconceptions) are important goals in both secondary and tertiary science education. A prototype of an instructional task is presented which aims at improved problem-solving skills based on understanding of domain knowledge. In this task, comparing carefully selected solved problems by groups of students is utilised as a learning activity for the acquisition of adequate problem schemata. The task is designed as a part of the so-called UBP-program (UBP=Understanding Based Problem solving) currently being developed, for education in science. The result of an evaluative study for the field of mechanics is presented. The UBP-task appears apt to improve problem-solving skills at a less advanced level of physics education (e.g., 10th grade), especially for students normally performing poorly—who are often girls.  相似文献

Clinically integrated curricula in health science education has been shown to promote the development of problem-solving schema and positively impact knowledge acquisition. Despite its’ purported benefits, this type of curricula can impose a high cognitive load, which may negatively impact novice learners’ knowledge acquisition and problem-solving schema development. Introducing explicit clinical reasoning instruction within pre-professional undergraduate basic science courses may limit factors that increase cognitive load, enhance knowledge acquisition, and foster developing clinical problem-solving skills. This study, conducted over the Fall and Spring semesters of the 2018–2019 school year, sought to evaluate whether the implementation of a clinical reasoning instructional intervention within a clinically integrated pre-professional undergraduate general human anatomy course influenced students’ acquisition of anatomical knowledge and development of clinical problem-solving skills. Results of the study were mixed regarding the acquisition of anatomical knowledge. Both the intervention and comparison groups performed similarly on multiple choice examinations of anatomical knowledge. However, the clinical reasoning intervention positively impacted students’ ability to apply clinical reasoning skills to anatomically based clinical case studies. Results from M\mixed between-within subjects analysis of variance comparing scores on Written Clinical Reasoning Assessments revealed a significant interaction between time and group affiliation, with the groups receiving the interventions outperforming the comparison groups: Fall, P < 0.001; Spring, P < 0.001. The results of this study may imply that explicit clinical reasoning instruction within a clinically integrated undergraduate Human Anatomy course could hold potential for fostering students’ early clinical reasoning skills.  相似文献

The main purpose of this study was to examine possible gender differences in how junior high school students integrate printed texts and diagrams while solving science problems. We proposed the response style hypothesis and the spatial working memory hypothesis to explain possible gender differences in the integration process. Eye-tracking technique was used to explore these hypotheses. The results of eye-movement indices support the response style hypothesis. Compared to male students, female students spent more time and displayed more fixations in solving science problems. The female students took more time to read the print texts and compare the information between print-based texts and visual-based diagrams more frequently during the problem-solving process than the male students. However, no gender differences were found in the accuracy of their responses to the science problems or their performances in the spatial working memory task. Implications for psychological theory and educational practice are discussed.  相似文献

Talking for reasoning among Mexican primary school children   总被引:1,自引:0,他引:1  
We analysed the development and promotion of ‘exploratory talk’ as a discursive tool to facilitate collective and individual reasoning in Mexican primary school children, following Mercer et al. (Br. Educ. Res. J. 25 (1999) 95) in the UK equivalent experimental and control groups of primary school children were administered a group and an individual problem-solving test before and after training. Teachers of the experimental groups trained their respective students to use competently exploratory talk to make their reasoning visible to others for solving diverse problems. In contrast with control children, experimental ones used significantly more exploratory talk, and this gain was accompanied by a substantial improvement in group and individual problem-solving. Results confirm sociocultural claims that language can function as a powerful tool to facilitate reasoning in social contexts, confirming previous UK findings.  相似文献

Present research in problem solving appears to be primarily concerned with problem-solving methods and with degree of knowledge acquisition. A brief argument is advanced that this conceptualization is incomplete because of failure to consider individual differences among problem solvers (other than in problem-solving methods and extent of knowledge). A viable theory of problem-solving instruction must take into account all three areas. Evidence for the argument is presented in the form of data on problem-solving success in junior high school students with extreme scores on Witkin's field independence-field dependence measure of cognitive style. Problem-solving protocols are examined as a second source of data. Field independent students significantly out-performed field dependent students on the problems. Examination of protocols revealed consistent performance patterns favoring field independent students.  相似文献

This study investigated the students’ learning process of the concept of concentration at the elementary school level in Taiwan. The influence of different representational types on the process of proportional reasoning was also explored. The participants included nineteen third-grade and eighteen fifth-grade students. Eye-tracking technology was used in conducting the experiment. The materials were adapted from Noelting’s (1980a) “orange juice test” experiment. All problems on concentration included three stages (the intuitive, the concrete operational, and the formal operational), and each problem was displayed in iconic and symbolic representations. The data were collected through eye-tracking technology and post-test interviews. The results showed that the representational types influenced students’ solving of concentration problems. Furthermore, the data on eye movement indicated that students used different strategies or rules to solve concentration problems at the different stages of the problems with different representational types. This study is intended to contribute to the understanding of elementary school students’ problem-solving strategies and the usability of eye-tracking technology in related studies.  相似文献
