Animations may facilitate learning by providing external support for visual–spatial mental processing. Facilitation is challenged by findings that demonstrate involvement of spatial abilities in learning from animations, because this involvement indicates active internal visual–spatial processing. In the present study, learners attended to a system-paced multimedia presentation in which a verbal–auditory explanation was concurrently synchronized either with animation, with static core pictures, or with enriched static pictures that showed additional intermediate steps and arrows indicating motion. Results demonstrated better learning success with animations and with enriched static pictures than with static pictures. Spatial abilities were not substantively related to learning success with animations or with static pictures, but they played a crucial role for learning success with enriched static pictures. It is concluded that active visual–spatial processing was recruited with enriched static pictures. With animations, learning was truly facilitated by external support for visual–spatial mental processing.  相似文献

Two component skills are thought to be necessary for successful word problem solving: (1) the production of visual-schematic representations and (2) the derivation of the correct relations between the solution-relevant elements from the text base. The first component skill is grounded in the visual–spatial domain, and presumed to be influenced by spatial ability, whereas the latter is seated in the linguistic–semantic domain, and presumed to be influenced by reading comprehension. These component skills as well as their underlying basic abilities are examined in 128 sixth grade students through path analysis. The results of the path analysis showed that both component skills and their underlying basic abilities explained 49% of students’ word problem solving performance. Furthermore, spatial ability and reading comprehension both had a direct and an indirect relation (via the component skills) with word problem solving performance. These results contribute to the development of instruction methods that help students using these components while solving word problems.  相似文献

In two experiments, participants made inferences from weather maps, before and after they received instruction about relevant meteorological principles. Different versions of the maps showed either task-relevant information alone, or both task-relevant and task-irrelevant information. Participants improved on the inference task after instruction, indicating that they could apply newly acquired declarative knowledge to make inferences from graphics. In Experiment 1, participants spent more time viewing task-relevant information and less time viewing task-irrelevant information after instruction, and in Experiment 2, the presence of task-irrelevant information impaired performance. These results show that domain knowledge can affect information selection and encoding from complex graphics as well as processes of interpreting and making inferences from the encoded information. They also provide validation of one principle for the design of effective graphical displays, namely that graphics should not display more information than is required for the task at hand.  相似文献

Inquiry-based lessons have been demonstrated to improve children’s scientific thinking (i.e. reasoning abilities and domain-specific knowledge). Although empirical evidence shows that inquiry-based learning requires instruction, research comes from two approaches that have not been bridged yet: direct instruction of scientific reasoning and teacher training of verbal support. We investigated how these two types of instruction separately or combined strengthened children’s scientific thinking by comparing four conditions: baseline, direct instruction, verbal support, and a combined approach. Effectiveness of an inquiry-based lesson series on scientific reasoning abilities, vocabulary, and domain-specific knowledge (near and far transfer) were studied among 301 fourth graders. Results showed that both approaches strengthened different components of scientific reasoning abilities, and that a combination of instructions was most effective for scientific reasoning abilities, vocabulary, and domain-specific knowledge. Domain-specific knowledge acquisition was strengthened only when both instructions were provided. It can thus be concluded that each type of instruction has unique contributions to children’s science learning and that these instructions complement each other. Our study thus showed that inquiry-based lesson series when preceded by direct instruction of scientific reasoning and scaffolded with verbal support are most effective.  相似文献

Higher spatial skills are associated with increased interest, performance, and creativity in STEM fields (Science, Technology, Engineering, Mathematics). However, evidence for causal relations between spatial skills and STEM performance remains scarce. In this study, we test the extent to which mechanical problem solving, a spatially demanding STEM activity, facilitates spatial performance. Participants (N = 180) were randomly assigned to one of four training conditions: mechanical reasoning with a hands-on component; mechanical reasoning without a hands-on component; an active control condition involving spatial training with cross-sectioning; and an active control group involving a reading exercise. All participants were tested immediately before, after, and one-week following training. Both mechanical conditions were associated with enhanced spatial visualization performance, an effect that was similar for both conditions and remained stable across immediate and delayed post-tests. These findings suggest that mechanical problem solving is a potentially viable approach to enhancing spatial thinking.  相似文献

In this article we present research concerning important aspects of domain-specific giftedness. Specifically, we address the evidence regarding the relationship between specific abilities and achievement. Empirical evidence suggests that specific abilities have been used widely and validly for identification of exceptional talent in performance domains, and mathematical and spatial reasoning ability have demonstrated predictive validity for achievement in science, technology, engineering, and mathematics (STEM) domains. We note that domains of talent have unique trajectories and discuss four critical aspects of domain-specific giftedness. These include the developmental nature of giftedness (giftedness moves from potential to competency to expertise and possibly to eminence over time); the temporal nature of giftedness (that domains vary in their starting, peak, and ending points); the contextual aspect of giftedness (societal value of some domains over others, changing of domains and emergence of new domains, and the environmental influences in fostering domain-specific achievement); and the relative nature of giftedness (childhood giftedness is advancement relative to age peers, and adult giftedness is exceptional achievement relative to other domain experts). Finally, we present some implications of a domain perspective on giftedness for educational practice.  相似文献

Our research aims to identify domain-specific similarities and differences of externalized cognitive structures. Cognitive structure, also known as knowledge structure or structural knowledge, is conceived as the manner in which an individual organizes the relationships of concepts in memory. By diagnosing these structures precisely, even partially, the educator comes closer to influencing them through instructional settings and materials. Our assessment and analysis of cognitive structures is realized within the HIMATT tool, which automatically generates four quantitative indicators for the structural entities of written text or causal maps. In our study, participants worked on the subject domains biology, history, and mathematics. Results clearly indicate different structural and semantic features across the three subject domains. Additionally, we found that written texts and causal maps seem to represent different structure and content across the three subject domains when compared to an expert??s representation. We conclude with a general discussion, instructional implications and suggestions for future research.  相似文献

It was investigated how domain-specific knowledge, fluid intelligence, vocational interest and work-related self-efficacy predicted domain-specific problem-solving performance in the field of office work. The participants included 100 German VET (vocational education and training) students nearing the end of a 3-year apprenticeship program as an industrial clerk (n?=?63) which usually leads to a position in office work, lower or middle management, or a similar apprenticeship program to become IT-systems management assistants (n?=?37). The participants worked on three computer-based problem scenarios dealing with operative controlling, a relevant domain to both training occupations, and completed further assessments to measure the variables listed above. Theoretical considerations, prior research and domain analyses suggested that industrial clerks would have greater domain-specific problem-solving competence (H1a) and domain-specific knowledge (H1b) than IT-systems management assistants and that domain-specific knowledge would be the strongest predictor of problem-solving competence (H2: “knowledge-is-power” hypothesis); all hypotheses were confirmed. Hypothesis 3, the “Elshout-Raaheim hypothesis,” predicts that fluid intelligence and problem-solving competence are most strongly correlated in the context of intermediate levels of task-related content knowledge, however the highest correlation was found in the group with low domain-specific knowledge. The findings suggest that intelligence plays a minor role in later stages of competence development whereas typical problem situations in later stages particularly require prior knowledge. The relationship of intelligence, knowledge and problem solving as well as limitations of the study, particularly weaknesses in the measurement of non-cognitive dispositions, are discussed.  相似文献

ABSTRACT

The authors find justification for integrating science, technology, engineering, and mathematics (STEM) in the complex problems that today's students will face as tomorrow's STEM professionals. Teachers with individual subject-area specialties in the STEM content areas have limited experience in integrating STEM. In this study, the authors investigated the conceptual changes of secondary school teachers teaching domain-specific STEM courses after a week-long professional development experience integrating earthquake engineering and domain-specific concepts. They documented and then triangulated outcomes of the experience using participating teachers' concept maps and teacher-generated written materials, respectively. Statistical comparisons of participants' concept maps revealed significant increases in their overall understanding of earthquake engineering and more accurate linkages with and among science domain-specific concepts. Content analyses of teachers' learning products confirmed the concept map analysis and also provided evidence of transfer of workshop learning experiences into teacher-designed curriculum products accurately linking earthquake engineering and domain-specific STEM content knowledge.  相似文献

Windows into the mind   总被引:1,自引:0,他引:1  
As faculty, our goals for students are often tacit, hidden not only from students but from ourselves as well. We present a conceptual framework for considering teaching goals – what we want our students to achieve – that encourages us to think more broadly about what we mean by achieving in our knowledge domains. This framework includes declarative knowledge (“knowing that”), procedural knowledge (“knowing how”), schematic knowledge (“knowing why”) and strategic knowledge (“knowing when, where and how our knowledge applies”). We link the framework to a variety of assessment methods and focus on assessing the structure of declarative knowledge – knowledge structure. From prior research, we know that experts and knowledgeable students have extensive, well-structured, declarative knowledge; not so novices. We then present two different techniques for assessing knowledge structure – cognitive and concept maps, and a combination of the two – and provide evidence on their technical quality. We show that these maps provide a window into the structure of students declarative knowledge not otherwise tapped by typical pencil-and-paper tests. These maps provide us with new teaching goals and new evidence on student learning.Based on an invited address, Facoltá di Ingegneria dell’Universitá degli Studi di Ancona, June 27, 2000.

Spatial abilities have been correlated to anatomy knowledge assessment and spatial training has been found to improve spatial abilities in previous systematic reviews. The objective of this systematic review was to evaluate spatial abilities training in anatomy education. A literature search was done from inception to 3 August 2017 in Scopus® and several databases on the EBSCOhost platform. Citations were reviewed and those involving anatomy education, an intervention, and a spatial abilities test were retained and the corresponding full-text articles were reviewed for inclusion. Before and after training studies, as well as comparative training programs, relating a spatial training intervention to spatial abilities were eligible. Of the 2,405 citations obtained, 52 articles were identified and reviewed, yielding eight eligible articles. Instruction in anatomy and mental rotations training were found to improve spatial abilities. For the seven studies retained for the meta-analysis that included the effect of interventions on spatial abilities test scores, the pooled treatment effect difference was 0.49 (95% CI [0.17; 0.82]; n = 11) improvement. For the two studies that included the practice effect on spatial abilities test scores in a control group, the pooled treatment effect difference was 0.47 (95% CI [−0.03; 0.97]; n = 2) improvement. In these two studies, the impact of the intervention on spatial abilities test scores was found despite the practice effect. Evidence was found for improvement of spatial abilities in anatomy education using instruction in anatomy and mental rotations training.  相似文献

This study examined the interrelationship between tenth-grade students’ problem solving ability (PSA) and their domain-specific knowledge (DSK) as well as reasoning skills (RS) in a secondary school of Taiwan. The PSA test was designed to emphasize students’ divergent-thinking ability (DTA) and convergent-thinking ability (CTA) subscales in the area of Earth science. Two hundred and sixty tenth graders who were enrolled in six Earth science classes at a public senior high school located in the eastern region of Taiwan were participants. Major findings are as follows: (a) A significantly positive correlation existed between students’ PSA and their DSK and RS, approaching large effect sizes; (b) Both students’ DSK and RS significantly explained the variance of their PSA with large effect sizes; (c) Students’ RS could more significantly explain the variance of their DTA subscale with medium effect size while DSK might more significantly explain the variance of their CTA, approaching large effect size. The research suggests that more emphasis should be placed on the reasoning skills when developing students’ divergent-thinking abilities, while stressing more domain-specific knowledge when students’ convergent-thinking ability is considered.  相似文献

Anatomy knowledge has been found to include both spatial and non‐spatial components. However, no systematic evaluation of studies relating spatial abilities and anatomy knowledge has been undertaken. The objective of this study was to conduct a systematic review of the relationship between spatial abilities test and anatomy knowledge assessment. A literature search was done up to March 20, 2014 in Scopus and in several databases on the OvidSP and EBSCOhost platforms. Of the 556 citations obtained, 38 articles were identified and fully reviewed yielding 21 eligible articles and their quality were formally assessed. Non‐significant relationships were found between spatial abilities test and anatomy knowledge assessment using essays and non‐spatial multiple‐choice questions. Significant relationships were observed between spatial abilities test and anatomy knowledge assessment using practical examination, three‐dimensional synthesis from two‐dimensional views, drawing of views, and cross‐sections. Relationships between spatial abilities test and anatomy knowledge assessment using spatial multiple‐choice questions were unclear. The results of this systematic review provide evidence for spatial and non‐spatial methods of anatomy knowledge assessment.

Previous studies [Scott & Ehri (1990) Journal of Reading Behavior22: 149–166; de Abreu & Cardoso-Martins (1998) Reading and Writing:An Interdisciplinary Journal 10: 85–104] have shown thatprereaders who know the names of the lettersuse a visual–phonological strategy to learn toread words in which the names of one or moreletters can be clearly detected in thepronunciation of the words. The present resultsextend these findings by showing that BrazilianPortuguese-speaking prereaders who know thenames of the letters can process letter–soundrelations to learn to read spellings in whichthe letters correspond to phonemes, not toletter names. Following Ehri & Wilce'sprocedure [(1985) Reading Research Quarterly 20:163–179], Brazilian preschool childrenlearned to read two types of simplifiedspellings: phonetic spellings, that is,spellings in which the letters corresponded tophonemes in the pronunciation of the words(e.g., SPT for sapato), and visualspellings, that is, spellings in which theletters did not correspond to sounds in thepronunciation of the words, but which werevisually more salient (e.g., VST for pijama). The children learned to read thephonetic spellings more easily than the visualspellings, suggesting that they recognized theletter–phoneme relations in learning to readthe phonetic spellings. This interpretation isbolstered by the results of correlationalanalyses between knowledge of letter sounds andperformance on the two word-learning tasks.While knowledge of letter–phonemecorrespondences did not correlate withperformance on the word-learning task with thevisual spellings, it correlated significantlyand positively with the children's ability tolearn to read the phonetic spellings.  相似文献

The purpose of the present study was to investigate the structure of metacognitive knowledge in fifth grade pupils and its relation to school achievement. Since the structure of metacognitive knowledge is controversially discussed with little empirical evidence for either its domain specificity or its domain transferability, the debate remains somewhat hypothetical up to date. In theory it is assumed that the development of metacognitive knowledge begins highly domain and situation-specific and becomes more flexible and domain-transcending with practice and experience (Borkowski et al. 2000). As standardized measures to assess metacognitive knowledge of students in the age group under investigation were missing, newly developed instruments were applied to assess the domain-specific metacognitive knowledge in reading and mathematics as well as domain-transcending metacognitive knowledge. The influences of domain-specific and general metacognitive knowledge on school achievement in the two domains were analyzed. While findings on the structure of metacognitive knowledge indicate some degree of domain specificity, they also point out a strong relation between general metacognitive knowledge and domain-specific metacognitive knowledge. The cross-sectional relation between metacognitive knowledge and academic achievement were relatively low. Implications for future research will be discussed.  相似文献

The present study investigates the relation between spatial ability and visuo-spatial and verbal working memory in spatial text processing. In two experiments, participants listened to a spatial text (Experiments 1 and 2) and a non-spatial text (Experiment 1), at the same time performing a spatial or a verbal concurrent task, or no secondary task. To understand how individuals who differ in spatial ability process spatial text during dual task performance, spatial individual differences were analyzed. The tasks administered were the Vandenberg and Kuse [Vandenberg, S. G., & Kuse, A. R. (1978). Mental rotation, a group test of three-dimensional spatial visualization. Perceptual and Motor Skills, 47, 599-604.] mental rotation test (MRT) and a reading comprehension task (RCT). Individuals with high (HMR) and low (LMR) mental rotation differed in MRT scores but had similar RCT performance. Results showed that the HMR group, in contrast with LMR counterparts, preserved good spatial text recall even when a spatial concurrent task was performed; however, Experiment 2 revealed a modification of spatial concurrent task performance in LMR as well in HMR group. Overall, results suggest that HMR individuals have more spatial resources than LMR individuals, allowing them to compensate for spatial working memory interference, but only to a limited extent, given that the processing of spatial information is still mediated by VSWM.  相似文献

This study investigates the relationships of domain-general cognitive abilities and domain-specific verbal and mathematical abilities to students' educational characteristics when two theoretically grounded, but competing structural models are applied. In the standard model, a single latent ability causes interindividual differences in the corresponding measures. In the nested-factor model, interindividual differences are caused by two independent cognitive abilities: general cognitive ability and domain-specific ability. The two models were examined using data from 29,386 ninth graders. The results show that findings on the relations between domain-specific abilities and students' socio-economic status, general school satisfaction, educational aspirations, domain-specific interests, and subject-specific grades may differ substantially depending on the structural model applied. Implications for educational research and measurement as well as for students' motivational and cognitive development are discussed.  相似文献

Sex differences favoring males in spatial abilities have been known by cognitive psychologists for more than half a century. Spatial abilities have been related to three‐dimensional anatomy knowledge and the performance in technical skills. The issue of sex differences in spatial abilities has not been addressed formally in the medical field. The objective of this study was to test an a priori hypothesis of sex differences in spatial abilities in a group of medical graduates entering their residency programs over a five‐year period. A cohort of 214 medical graduates entering their specialist residency training programs was enrolled in a prospective study. Spatial abilities were measured with a redrawn Vandenberg and Kuse Mental Rotations Tests in two (MRTA) and three (MRTC) dimensions. Sex differences favoring males were identified in 131 (61.2%) female and 83 (38.8%) male medical graduates with the median (Q1, Q3) MRTA score [12 (8, 14) vs. 15 (12, 18), respectively; P < 0.0001] and MRTC score [7 (5, 9) vs. 9 (7, 12), respectively; P < 0.0001]. Sex differences in spatial abilities favoring males were demonstrated in the field of medical education, in a group of medical graduates entering their residency programs in a five‐year experiment. Caution should be exerted in applying our group finding to individuals because a particular female may have higher spatial abilities and a particular male may have lower spatial abilities.
