Purpose: The purpose of this review was to investigate the current state of knowledge about the effectiveness of concept mapping in nursing education. Methods: An integrative review adapted a systematic approach. Also, after an extensive search from different databases, ten articles were retrieved and fully reviewed. Results: The ten reviewed articles were adopted quantitative, qualitative, and mixed method designs. Four main themes were identified: 1) from passive to active learners, 2) establishing new knowledge, 3) improving cognitive abilities, and 4) self-confidences in clinical work. Conclusion: Nursing literature supports the importance of including concept maps in nursing education. Educators believe that concept mapping is a motivating teaching strategy, hence, it is fostering the long-term and meaningful learning. Also, the findings of this study might encourage nursing educators to evaluate the current teaching strategies, also, this review might initiate future studies with larger sample 展开更多

A concept map is a diagram depicting relationships among concepts which is used as a knowledge representation tool in many knowledge domains. In this paper, we build on the modeling framework of Hui et al. (2008) in order to develop a concept map suitable for testing the empirical evidence of theories. We identify a theory by a set of core tenets each asserting that one set of independent variables affects one dependent variable, moreover every variable can have several operational definitions. Data consist of a selected sample of scientific articles from the empirical literature on the theory under investigation. Our “tenet map” features a number of complexities more than the original version. First the links are two-layer: first-layer links connect variables which are related in the test of the theory at issue;second-layer links represent connections which are found statistically significant. Besides, either layer matrix of link-formation probabilities is block-symmetric. In addition to a form of censoring which resembles the Hui et al. pruning step, observed maps are subject to a further censoring related to second-layer links. Still, we perform a full Bayesian analysis instead of adopting the empirical Bayes approach. Lastly, we develop a three-stage model which accounts for dependence either of data or of parameters. The investigation of the empirical support and consensus degree of new economic theories of the firm motivated the proposed methodology. In this paper, the Transaction Cost Economics view is tested by a tenet map analysis. Both the two-stage and the multilevel models identify the same tenets as the most corroborated by empirical evidence though the latter provides a more comprehensive and complex insight of relationships between constructs. 展开更多

Children with Developmental Coordination Disorder (DCD) often seem to possess a narrow repertoire of cognitive strategies. In particular, they have difficulties in learning and internalizing the rules and strategies that other people intuitively use to approach common everyday problems. As a result, they often appear to have organizational, planning, memory and learning difficulties. The article proposes using a Concept Map (CM) as a visual strategy to facilitate interaction between a child with DCD, his/her family and therapist, as reflected in Client Centred and cognitive approaches. The CM is used as a method of assisting the child to identify, develop and utilize cognitive strategies in order to manage daily tasks effectively, as a tool in organizing his own therapy and in order to encourage participation. A demonstration of the concept mapping usefulness is brought by a case report. Further uses of concept mapping as a useful strategy within the framework of intervention remain to be studied. 展开更多

Background: The rapid change of health care delivery affirms the need for a change in the culture of nursing education through identifying the challenge to nursing faculty that many teach in the way they were taught, and suggesting a focus on the exploration of new teaching methods and student learning, rather than only focus on content coverage. Objectives: To examine the impact of concept mapping on caring efficacy of Palestinian nursing students. Methods: A quasi-experimental design, pre-post test, two groups (intervention and control group) were used. Convenience sample of 80 (40 participants in each group) nursing students from Arab American University, Jenin. Caring Efficacy was measured by Caring Efficacy Scale. The statistical tests such as t-test (independent and paired t-test) were used to examine the effect of concept mapping on caring efficacy of the fourth year nursing students at their clinical training. Results: Independent-samples t-test revealed statistically significant differences between the two groups in caring efficacy (t = 2.589, df = 78, P = 0.011);students in the intervention group showed higher level of caring efficacy than students in the control group during their clinical training. Conclusion: Concept mapping was found to be an effective teaching method for nursing students. The use of concept mapping is useful in enhancing meaningful learning. 展开更多

In 2006 anew biology curriculum called “Human Biology: Emphasizing the Role of Homeostasis” was introduced into the Israeli high school system. Complex systems like those that make up the human body have become increasingly important as a focus of high school education. This study examines the effectiveness of the concept map as a assessment tool for students’ systems thinking, a tool that provides researchers with a detailed picture of the systems thinking development taking place within individual students. The content of the students’ concept maps was translated into information about students’ system thinking using the Systems Thinking Hierarchy (STH) model, a model in which system thinking is categorized according to eight hierarchical characteristics or abilities. The goal was to use the maps to characterize Israeli high school students’ understanding of the body’s systemic nature. To do this, we identified the extent to which the students understand three central elements of systems, namely hierarchy, homeostasis, and dynamism, and then analyzed this understanding according to its place within the hierarchical stages of the STH model. The extensive qualitative data analysis of 48 concept maps made by 11th grade biology majors suggest that the strength of the concept map is in its ability to describe the first two levels of system thinking (analysis and synthesis). However, it proved less successful in eliciting evidence of the third and highest level, particularly of students’ understanding of patterns, of homeostasis and their capacity for temporal thinking. 展开更多

The present study applies Dr.He Yuanjian's CMT(Conceptual Mapping Theory) to focus on the strategy use of translating Chinese folklore concepts in Hong Lou Meng(i.e.indigenous concepts related to etiquettes and customs) by Yang Xianyi and his wife Gladys Yang on the observations of the translators'strategies and the distributional tendencies of translation strategies so as to testify CMT on empirical grounds.Whether it holds true that the preservation of the alien source concepts through translation depends on how successfully they are mapped into the target conceptual system leads to the attempts to study on the distributional tendency of translation strategies of translation tasks,especially,of translating folkloric concepts in this paper.As a result,the tentative outcome of the data observed supports that the concept-mediation theoretic approach to translation process seems able to account for how cognitive constraints affect the production of mapping the unshared concepts. 展开更多

With this work, we introduce a novel method for the unsupervised learning of conceptual hierarchies, or concept maps as they are sometimes called, which is aimed specifically for use with literary texts, as such distinguishing itself from the majority of research literature on the topic which is primarily focused on building ontologies from a vast array of different types of data sources, both structured and unstructured, to support various forms of AI, in particular, the Semantic Web as envisioned by Tim Berners-Lee. We first elaborate on mutually informing disciplines of philosophy and computer science, or more specifically the relationship between metaphysics, epistemology, ontology, computing and AI, followed by a technically in-depth discussion of DEBRA, our dependency tree based concept hierarchy constructor, which as its name alludes to, constructs a conceptual map in the form of a directed graph which illustrates the concepts, their respective relations, and the implied ontological structure of the concepts as encoded in the text, decoded with standard Python NLP libraries such as spaCy and NLTK. With this work we hope to both augment the Knowledge Representation literature with opportunities for intellectual advancement in AI with more intuitive, less analytical, and well-known forms of knowledge representation from the cognitive science community, as well as open up new areas of research between Computer Science and the Humanities with respect to the application of the latest in NLP tools and techniques upon literature of cultural significance, shedding light on existing methods of computation with respect to documents in semantic space that effectively allows for, at the very least, the comparison and evolution of texts through time, using vector space math. 展开更多
