In the context of recent studies on writing to learn, concept maps are constructed in an attempt to make knowledge structures and conceptual change explicit. These graphic representations are based on the concepts and semantic relations in a student's text. However, a concept map does not give insight into the rhetorical text structure and other rhetorical features, nor does it show the way concepts are located and connected in this structure. Since the dialectic between content knowledge and rhetorical knowledge is essential in the process of 'knowledge transforming', and consequently conceptual change, an analysis tool that integrates both analysis of rhetorical text structure and of semantic structures in text is needed. In a pilot study of a forthcoming research project about writing to learn in the content areas in primary education, an instrument was designed for integrated text analysis and graphic representation. The analysis and representations were demonstrated with data collected from ll-to-12 year old students, who wrote an explanatory text for younger students about a climate issue. Revision was triggered by asking the student whether he expected a younger pupil to understand the written explanation. An analysis and graphic representations of two texts written by two different students focused on location and use of concepts, expansions of meaning of these concepts, and connections between concepts through coherence relations, all embedded in the rhetorical text structure. It was concluded that the analysis tool proposed here makes it possible to compare students' knowledge structures and accordingly can provide insight into conceptual changes, relative to writing.

Conceptual change theories assume that knowledge structures grow during the learning process but also get reorganized. Yet, this reorganization process itself is hard to examine. By using concept maps, we examined the changes in students’ knowledge structures and linked it to conceptual change theory. In a longitudinal study, thirty high-achieving students (M = 14.41 years) drew concept maps at three timepoints across a teaching unit on magnetism and electrostatics. In total, 87 concept maps were analyzed using betweenness and PageRank centrality as well as a clustering algorithm. We also compared the students’ concept maps to four expert maps on the topic. Besides a growth of the knowledge network, the results indicated a reorganization, with first a fragmentation during the unit, followed by an integration of knowledge at the end of the unit. Thus, our analysis revealed that the process of conceptual change on this topic was non-linear. Moreover, the terms used in the concept maps varied in their centrality, with more abstract terms being more central and thus more important for the structure of the map. We also suggest ideas for the usage of concept maps in class.

Concept mapping was developed as a method of displaying and organizing hierarchical knowledge structures. Using the new, multidimensional presentation software Prezi, we have developed a new teaching technique designed to engage higher-level skills in the cognitive domain. This tool, synthesis mapping, is a natural evolution of concept mapping, which utilizes embedding to layer information within concepts. Prezi’s zooming user interface lets the author of the presentation use both depth as well as distance to show connections between data, ideas, and concepts. Students in the class Biology of Cancer created synthesis maps to illustrate their knowledge of tumorigenesis. Students used multiple organizational schemes to build their maps. We present an analysis of student work, placing special emphasis on organization within student maps and how the organization of knowledge structures in student maps can reveal strengths and weaknesses in student understanding or instruction. We also provide a discussion of best practices for instructors who would like to implement synthesis mapping in their classrooms.

Set pieces are important for the success of football teams, with the corner kick being one of the most game defining events. The aim of this research was twofold: (1) to analyze the corner kicks of a senior football amateur team, and (2) to compare the corner kicks of successful and unsuccessful teams (of the 2020/21 sporting season). In total, 500 corners were observed using a bespoke notational analysis tool, using a specific observational instrument tool (8 criteria; 25 categories). Out of the 500 corner kicks, 6% resulted in a goal. A greater number of direct corners using inswing trajectories were performed (n = 54%). Corners were delivered to central and front post areas most frequently (n = 79%). Five attackers were most predominantly used for offensive corners (n = 58%), but defenders won the ball more frequently (n = 44%). Attempts at goal occurred following a corner most commonly from outside of the box (n = 7%). Goals were scored most frequently with the foot (n = 16%) and head (n = 15%). Successful teams are more effective at reaching the attackers and score more goals directly from corners. Unsuccessful teams deliver more corner kicks out of play, the first touch is more frequently from the opposition defenders, and fewe goals are scored from corner kicks. The study provides an insight into the determining factors and patterns that influence corner kicks and success in football matches. This information should be used by coaches to prepare teams for both offensive and defensive corner kicks to increase team success and match outcomes.

Self-tuning physical database organization involves tools that determine automatically the best solution concerning partitioning, placement, creation and tuning of auxiliary structures (e.g. indexes), based on the workload. To the best of our knowledge, no tool has focused on a relevant issue in parallel databases and in particular data warehouses running on common off-the-shelf hardware in a sharednothing configuration: determining the adequate tradeoff for balancing load and availability with costs (storage and loading costs). In previous work, we argued that effective load and availability balancing over partitioned datasets can be obtained through chunk-wise placement and replication, together with on-demand processing. In this work, we propose ChunkSim, a simulator for system size planning, performance analysis against replication degree and availability analysis. We apply the tool to illustrate the kind of results that can be obtained by it. The whole discussion in the chapter provides very important insight into data allocation and query processing over shared-nothing data warehouses and how a good simulation analysis tool can be built to predict and analyze actual systems and intended deployments.

Abstract Background Several literature reviews have been published focusing on the prevalence and/or preventability of hospital readmissions. To our knowledge, none focused on the different causes which have been used to evaluate the preventability of readmissions. Insight into the range of causes is crucial to understand the complex nature of readmissions. With this review we aim to: 1) evaluate the range of causes of unplanned readmissions in a patient journey, and 2) present a cause classification framework that can support future readmission studies. Methods A literature search was conducted in PUBMED and EMBASE using “readmission” and “avoidability” or “preventability” as key terms. Studies that specified causes of unplanned readmissions were included. The causes were classified into eight preliminary root causes: Technical, Organization (integrated care), Organization (hospital department level), Human (care provider), Human (informal caregiver), Patient (self-management), Patient (disease), and Other. The root causes were based on expert opinions and the root cause analysis tool of PRISMA (Prevention and Recovery Information System for Monitoring and Analysis). The range of different causes were analyzed using Microsoft Excel. Results Forty-five studies that reported 381 causes of readmissions were included. All studies reported causes related to organization of care at the hospital department level. These causes were often reported as preventable. Twenty-two studies included causes related to patient’s self-management and 19 studies reported causes related to patient’s disease. Studies differed in which causes were seen as preventable or unpreventable. None reported causes related to technical failures and causes due to integrated care issues were reported in 18 studies. Conclusions This review showed that causes for readmissions were mainly evaluated from a hospital perspective. However, causes beyond the scope of the hospital can also play a major role in unplanned readmissions. Opinions regarding preventability seem to depend on contextual factors of the readmission. This study presents a cause classification framework that could help future readmission studies to gain insight into a broad range of causes for readmissions in a patient journey. In conclusion, we aimed to: 1) evaluate the range of causes for unplanned readmissions, and 2) present a cause classification framework for causes related to readmissions.

This paper is a report of research on the potential validity of concept maps as a representation of students’ knowledge of research methods in psychology. Concept maps may provide insight into the content and structure of students’ knowledge that traditional assessment methods do not. In this paper we examine the rationale underlying the use of concept maps and issues associated with their use. We also report a qualitative study in which we employed concept maps to assess students’ knowledge. Finally, there is a description of a potential application of concept mapping to the evaluation of students’ knowledge, currently being investigated by the authors.

Can the national focus on the NCTM's Standards be combined with the focus on writing to learn to streng then mathematics instruction? The NCTM's Professional Standards for Teaching Mathematics (1991) supports the use of writing as an instructional technique. The possibilities suggested for journal writing in the mathematics classroom challenged these authors to explore the available literature. Several studies appeared promising (Linn 1989; Miller and England 1989; Powell and Lopez 1989; Richards 1990; Rose 1989; Skiba 1990; Vukovich 1985; White and Dunn 1989). Where as most of these projects indicated that journal writing increased mathematical ability and decreased anxiety, too few studies actually delineated the content of the journal entries to any great extent. Moreover, many of the investigations did not consider the context within which students and teachers operate. The relevance and interaction of teacher, student, and subject matter were often overlooked. This situation further challenged the authors to extend and broaden the investigation of journal writing into a more global study-one of practical inquiry, not only exploring the cognitive and affective influences of journal writing but seeking situational insight into, and understanding of, the mathematics classroom.
