Developing Statistical Thinking in Schoolchildren: From Theory to Practice

Since 2022, the school course «Probability and Statistics» has been taught as a compulsory subject in all schools in Russia, and questions on it are included in the Unified State Exam. However, international experience in teaching the basics of statistics shows that this is not an easy task. It includes not only teaching students how to prove the theorems of mathematical statistics and explain the calculation of the median and variance, but also contributes to the development of statistical thinking in them – the ability to make decisions based on the analysis of empirical data. According to the authors, the statistical community cannot and should not replace teachers who promote the teaching of statistics at school, but it has the opportunity to make a significant contribution to this process.The article presents the experience of the All-Russian School competition on statistics «Trend», the All-Russian teacher competition for the best practices in teaching statistics «We train the best!», with the support of the territorial bodies of state statistics in St. Petersburg, Kirov and Rostov regions; master classes for hundreds of teachers teaching statistics in grades 7–11. In addition, the article presents plans for organizing a competition on civil statistics aimed at developing skills in working with statistical data, as well as teaching the basics of statistical analysis, the use of visualization tools, and the formation of citizenship through familiarity with objective statistical information

Improving community understanding of cascading effects of critical infrastructure service failure: An experimental interactive learning process

Effective disaster preparedness relies on the community's understanding of hazards and risks, emphasizing the need to address cascading effects from critical infrastructure failures due to natural hazards. Understanding cascading effects in communities facing multiple hazards is crucial due to the increasing complexity of critical infrastructure (CI) services. Limited awareness can amplify vulnerabilities and socioeconomic losses, and thus capacity building at the community level is essential for reducing hazard risks. This study utilized an interactive learning process (ILP), a participatory approach to engage the community in sharing experiences and building coping capacity for cascading effects. ILP was facilitated through facilitator-learner interaction and participatory exercises, aided by visualisation tools that enriched the learning experience of participants. The use of visualisation tools in ILP simplified comprehension of intricate interdependencies, helping participants to brainstorm and think critically to explore potential solutions. We explore the effectiveness of three visualisation tools that support the ILPs in improving community understanding of the cascading effects. Through experimentation and comparison, insights are gained into how learners engage with different ILPs and their impact on overall learning outcomes. The study concluded by selecting the visualisation tool supporting ILP that was effective in fostering engagement, improving understanding, and promoting knowledge retention.

Municipal Transport Route Planning Based on Fair Mobility Budget

Abstract A series of initiatives have been adopted in the European Union to address greenhouse gas emissions and establish a society that is resilient to climate change. In response to these initiatives, the implementation of mobility budgets offers a more precise strategy for addressing carbon footprints associated with travel. Prioritizing localized carbon footprint control, mobility budgets are calculated and customized according to distinct regions, goals, and target demographics. When prioritizing the mobility budget as the central objective in municipal transport route planning, the focus should encompass principles of fairness and equity in travel. This entails considering factors such as accessibility, variety of mobility choices, inclusivity of transportation modes, and social justice. Therefore, this article aims to formulate an enhanced activity modelling methodology that would aid data-driven decision-making in municipal transport route planning, while upholding the principles of travel fairness and equity. Тhe results obtained from scrutinizing data related to public bus services and mobile networks are presented. The evaluation of Jelgava’s city transportation network to facilitate mobility budget reduction is undertaken, and this assessment is based on an analysis of data derived from a survey on public transport use coupled with an examination of the city’s mobility budget. The research presents the communication challenges that municipalities will face in planning and implementing changes that are needed to meet the greenhouse gas emission targets and outlines the possible use of visualization tools for modelling, explanation and communication of scenarios.

Graph Theory: Enhancing Understanding of Mathematical Proofs Using Visual Tools

Mathematical culture is an essential part of general culture, and mathematical proof is the essence of mathematical culture, which plays an essential role in education for sustainable development. The presented research focuses on the following issue: Can the use of visual tools contribute to a better understanding of mathematical proofs presented within the framework of courses in graph theory? The research focuses on Czech university students of computer science. The presented results were achieved in a pedagogical experiment based on a pre-test, treatment and post-test design carried out during three academic years before the COVID pandemic period. In the pre-test and post-test phases, students were tested to determine their level of mathematical logic knowledge. Visual applications were used in teaching in the treatment phase. The research results clearly showed that the use of visual tools supporting formal explanation of mathematical proofs results in better understanding of the abstraction of the presented process and thus contributes significantly to sustainability in mathematical education. Thanks to the use of the mentioned visual tools during the COVID pandemic period, when schools had to switch to on-line education, the students’ results were comparable to those from face-to-face classes.

An Informed Decision Support Framework from a Strategic Perspective in the Health Sector

This paper introduces an informed decision support framework (IDSF) from a strategic perspective in the health sector, focusing on Saudi Arabia. The study addresses the existing challenges and gaps in decision-making processes within Saudi organizations, highlighting the need for proper systems and identifying the loopholes that hinder informed decision making.

It emphasizes the importance of integrating non-digital sources of information into the decision-making process, as well as considering factors that impact decision quality and accuracy. The study’s methodology involves data collection through interviews with decision makers, as well as the use of visualization tools to present and evaluate the results. The analysis of the collected data highlights the deficiencies in current decision-making practices and supports the development of the IDSF. The research findings demonstrate that the proposed framework outperforms existing approaches, offering improved accuracy and efficiency in decision making. Overall, this research paper contributes to the state of the art by introducing a novel IDSF specifically designed for the Saudi health sector.

Practitioners' ability to remotely develop understanding for personalised care and support planning: a thematic analysis of multiple data sources from the feasibility phase of the Dementia Personalised Care Team (D-PACT) intervention.

Practitioner understanding of patients' preferences, wishes and needs is essential for personalised health care i.e., focusing on 'what matters' to people based on their individual life situation. To develop such an understanding, dementia practitioners need to use communication practices that help people share their experiences, preferences, and priorities. Following the COVID-19 pandemic, dementia support is likely to continue to be delivered both remotely and in-person. This study analysed multiple sources of qualitative data to examine the views of practitioners, people living with dementia and carers, and researchers on how an understanding of what matters to people living with dementia can be developed remotely via telephone and video call. Access to environmental stimuli, the remote use of visual tools, peoples' tendency to downplay or omit details about their troubles and carers' ability to disclose privately were interpreted, through thematic analysis, to be factors affecting how practitioners sought to develop understanding remotely. Cumulatively, findings show that while remote support created unique challenges to practitioners' ability to develop understanding for personalised care, practitioners developed adaptive strategies to overcome some of these challenges. Further research should examine how, when and for whom these adapted practices for remote personalised care work, informing the development of evidence-based guidance and training on how practitioners can remotely develop the understanding required for personalised care.

A picture is worth a thousand words: advancing the use of visualization tools in implementation science through process mapping and matrix heat mapping

BackgroundIdentifying key determinants is crucial for improving program implementation and achieving long-term sustainment within healthcare organizations. Organizational-level complexity and heterogeneity across multiple stakeholders can complicate our understanding of program implementation. We describe two data visualization methods used to operationalize implementation success and to consolidate and select implementation factors for further analysis.MethodsWe used a combination of process mapping and matrix heat mapping to systematically synthesize and visualize qualitative data from 66 stakeholder interviews across nine healthcare organizations, to characterize universal tumor screening programs of all newly diagnosed colorectal and endometrial cancers and understand the influence of contextual factors on implementation. We constructed visual representations of protocols to compare processes and score process optimization components. We also used color-coded matrices to systematically code, summarize, and consolidate contextual data using factors from the Consolidated Framework for Implementation Research (CFIR). Combined scores were visualized in a final data matrix heat map.ResultsNineteen process maps were created to visually represent each protocol. Process maps identified the following gaps and inefficiencies: inconsistent execution of the protocol, no routine reflex testing, inconsistent referrals after a positive screen, no evidence of data tracking, and a lack of quality assurance measures. These barriers in patient care helped us define five process optimization components and used these to quantify program optimization on a scale from 0 (no program) to 5 (optimized), representing the degree to which a program is implemented and optimally maintained. Combined scores within the final data matrix heat map revealed patterns of contextual factors across optimized programs, non-optimized programs, and organizations with no program.ConclusionsProcess mapping provided an efficient method to visually compare processes including patient flow, provider interactions, and process gaps and inefficiencies across sites, thereby measuring implementation success via optimization scores. Matrix heat mapping proved useful for data visualization and consolidation, resulting in a summary matrix for cross-site comparisons and selection of relevant CFIR factors. Combining these tools enabled a systematic and transparent approach to understanding complex organizational heterogeneity prior to formal coincidence analysis, introducing a stepwise approach to data consolidation and factor selection.

Experiencing with visuals in accounting education: The case of integrated reports

In addition to the increasing use of visual tools (e.g., maps, graphs, images) in accounting, a growing literature is advocating more research on how visuals can also act as teaching aids to facilitate accounting education. This request particularly concerns the models of corporate reporting providing a multi-dimensional representation of organizations, such as integrated reporting, due to their greater complexity in comparison to traditional accounting reports. This article addresses such request by specifically investigating the potential of using visuals to support the students' learning of integrated reports by making the multi-dimensional content of these reports more accessible to learners. To achieve this aim, the article relies on Ausubel's meaningful learning theory and focuses on the use of a specific visual, named “resource map”. This visual was particularly studied with two group workshops, whose participants were involved in developing a resource map from the information of an integrated report. Our findings show that the use of visuals such as resource maps can support the teaching of integrated reports by helping learners to understand the main principles underlying these reports and acting as an ‘advance organizer’ of the data and information describing the multi-dimensionality of organizations.

СОВЕРШЕНСТВОВАНИЕ ОРГАНИЗАЦИИ И КОНТЕНТА ПАЛЕСТИНСКИХ ЧТЕНИЙ ЕПАРХИАЛЬНЫМИ ОТДЕЛАМИ ИМПЕРАТОРСКОГО ПРАВОСЛАВНОГО ПАЛЕСТИНСКОГО ОБЩЕСТВА В НАЧАЛЕ ХХ ВЕКА

The article deals with the issues of improving the organization and content of the Palestinian readings, held by the diocesan departments of the Imperial Orthodox Palestinian Society in the early twentieth century. The directions of the relevant changes are identified, which include: the creation of special commissions that coordinated the activities of conducting readings, attempts to form mobile groups for readings in rural areas, the use of visualization tools (“magic lanterns and “foggy pictures” for them), joint singing or performance musical works by an invited choir, demonstration of objects brought from the Holy Land (icons, stones, palm branches, shells, etc.) and, in some cases, distribution of pieces of earth and water from the Jordan River brought from Palestine. Informing about upcoming readings was carried out by publishing advertisements in newspapers, posting posters, orally in a church or educational institution, as well as striking a church bell. It is concluded that despite a number of successes in improving the content and organization of the Palestinian readings, the gradual accumulation of experience in their conduct, nevertheless, interesting findings, techniques proposed and put into practice by various diocesan departments were not analyzed and generalized, did not become the subject of general attention and replication, which served as a deterrent to the further growth of their popularity.

Design and validation of a handbook and photographic atlas on complementary food for use as a food education tool

The use of visual tools to calculate the adequate portion of the infant's food with an adequate education would allow to provide correct, simple and clear information to those responsible for their feeding. The objective was to design a manual and photographic atlas on complementary feeding (CF) for children between 6-12 months of age, to be used as a tool in food and nutrition education. Methods: The instrument was divided into two sections: a manual that includes advice on CF, and another corresponding to the food atlas, adapted to children aged 6 to 12 months. Content validity was performed by expert judgment, and the degree of agreement was measured using the Interclass Correlation Coefficient (ICC). The designed tool includes 47 foods, 323 photographs and 6 chapters, where key concepts were developed, feeding in the sick child, measurements and capacities of the utensils used, images accompanied with recommendations for food and nutritional education about consistency, frequency, quantity, progression in the incorporation of food, safety, recipes and menu ideas according to age. The atlas was divided into food groups, subdivided into raw and cooked foods, and in different presentations: puree, pieces and whole. The content validation showed a high percentage of general acceptance (85.86%) and reported a 95% ICC of 0.884 (0.712-0.973). The designed tool is very useful for carrying out nutrition counseling and education interventions for children of the age of starting their CF.

Increasing colorectal screenings with navigation at federally qualified health centers.

e18566 Background: From 2017 to 2019 there were a total of 423 federally qualified health center colonoscopy referrals (FQHC's) and only 81 (19%) patients followed through and had colonoscopies completed, identifying a significant gap in cancer care within an at risk populations. Methods: The Community Outreach team used a team based problem solving tools and data analytics to increase the number of patients who received colon screenings from FQHC’s. The team held brief, weekly huddles using a variety of continuous improvement tools to identify possible causes of the problem. The team identified 14 potential causes of the 19% gap in FQHC referrals to colonoscopy screenings. The potential causes were analyzed and 4 were identified as the root cause and grouped by common themes into the following opportunities for improvement: Poor engagement with FQHC's. Lack of knowledge on FQHC healthcare effectiveness data and information sets. No standardized workflow for FQHC referrals within the navigation process. Inefficient process for filling the number of screening appointment slots. After identifying the key potential causes, the team developed a task list with countermeasures for improvement and met weekly until the tasks were completed. Through root cause analysis the following key countermeasures were identified: Countermeasure 1: Increased engagement through weekly calls and monthly in person meetings at FQHC's. Countermeasure 2: Developed a quarterly newsletter for FQHC's to review colonoscopy referrals and completed screenings. Countermeasure 3: Developed and implemented a standardized process flow for receiving referrals from FQHC's. Countermeasure 4: Worked with the analytics team to create a dashboard to analyze the real time referrals and completed screenings along with sending e-mail notifications to the navigation program manager providing daily visual management of the number of new patient referrals from FQHC's. Results: After implementing the countermeasures, the community outreach team improved the number of FQHC referrals, from 423 in January of 2017 thru January 2019 to 1399 from January 2020 of December 2021.This was a 160% improvement. They also increased the number of completed colonoscopies from FQHC's from 81 in January of 2017 thru January of 2019 to 328 in January of 2020 thru December of 2021. This was a 200% improvement. The completed screening rate is 23% up from 18%. Conclusions: This project demonstrates the value of utilizing problem solving, visual management and data analytics for continuous quality improvement projects related to patient care. Cross-disciplinary collaboration should be explored with the use of visual tools and other resources to facilitate communication that is understood by all disciplines. The use of patient navigation to schedule patient screening appointments, reminders calls and resolved barriers improved no show rates.

Commentary on “Visualization in Operations Management Research”

This commentary paper highlights the merits of appropriate use of visualization tools in the original paper and summarizes potential research topics of visualization for operations management problems.

“In the Beginning Were the Data”: Economic Journalism as/and Data Journalism

ABSTRACT This article argues that the logic of data journalism has been a driving force in journalism since its beginnings, particularly in the case of economic journalism. Economic journalism has historically integrated five central aspects of data journalism: working with data and databases; the development of a conceptual infrastructure for data analysis and storytelling; the regular use of visualization tools; the application of new technologies to the peculiarities of economic data; and the integration of different professional profiles in the newsrooms. By analyzing economic journalism - the first among equals of data journalism - the article argues that data journalism can extract some lessons from economic news in order to improve the extension of data stories to every news beat. Four recommendations are drawn: the importance of a balanced management of data exuberance, their newsworthiness, and the analytical and conceptual tools used to interpret them; the aim of visualization should be more conceptual than descriptive, in order to simplify and clarify complex issues, and relationships between data, to make the explanation of current affairs more relevant and understandable; data journalism needs a harmonious integration of investigative projects with day-to-day coverage; and data journalism should avoid the perils of technological determinism.

Visualization Tools for Monitoring and Debugging a Cognitive Architecture using CST

In this work we address the use of visualization tools for developing intelligent agents built with Cognitive Architectures (CAs). Unfortunately, there are just a few discussions about this issue in the CAs literature. We start by bringing a summary on how this topic is currently being addressed within the community and further introduce our efforts in building visualization tools for both debugging and aiding the understanding of the inner mechanisms of a CA. For this, we propose the MindViewer, a visualization tool for monitoring and debugging CAs constructed with CST, the Cognitive Systems Toolkit. MindViewer encompasses a variety of charts that are used to monitor the inner details of the agents’ mind. Its Web version allows inspect even complex data structures and customize their generated graphics. We exemplify their capabilities through a experimental application based on a robot simulation inspired in Iowa Gambling Task.

Communication with relatives on prognosis of critically ill patients

Most patients admitted to the intensive care unit are unable to participate in decisions relating to their care. Therefore, physicians have to inform relatives on the condition of the patient, his evolution and the estimated prognosis. Numerous studies have shown that relatives commonly have inaccurate expectations of the patient’s prognosis, due to either misunderstanding of oral information by the physicians and/or overly optimistic beliefs. This may lead to undue prolongation of an ICU stay in the case of a poor prognosis. Several methods have been proposed in order to align relatives with the estimation of the patient’s prognosis by the physicians. The use of visual tools, added to oral information seems beneficial. Moreover, communication with relatives on the prognosis has to convey support and empathy.

Специфика использования визуализации в образовательном процессе вуза

Visualization is a method of visual presentation of information that affects the effectiveness of students' assimilation of new knowledge, the formation of the ability to critically comprehend the study material, and the ability to independently create schematic maps. We consider the essence of visualization, its functions and features, the influence on the student's mental and cognitive activity. The use of visualization is possible due to specifics of the perception of visual information by the student. The difference between visualization and visibility is revealed. We consider the indicators for the successful and effective use of visualization tools in the educational process of the university. The practical experience of using visualization during the learning process is analyzed. Despite the need to use visualization, there are certain difficulties in introducing its means into the educational process of higher education, but if we approach this issue competently, considering all the features, nuances and risks, the result of this activity will improve the quality of the educational process and increase the level of formation of universal competencies of students.

Comparative analysis of the txm business infographic: the use of visual tools to aid in the design creation process

Infographics were born to represent information, seeking to unite text and images to make information more straightforward to understand its context. Considering everything infographics represent in this informational society, we propose, based on a study of the elements that make up infographics, to validate the infographic referring to the TXM Business Methodology developed from another methodology used for brand creation and management TXM Branding. The primary purpose of creating such an infographic is to make information accessible to visualize the complete methodological process. Thus, the objective of this article is to analyze, based on the literature, the composition of the infographic of the TXM Business methodology in its two versions, allowing us to trace a relationship between them concerning their graphic elements. Therefore, to analyze and compare the two versions of TXM Business infographics, it was necessary to understand infographics and research construction methodologies to subsequently relate these learnings to the infographic and analyze it for future validation. The results point to a balanced composition that highlights the main approaches and information of the Methodology. The final object can be improved by understanding the field of infographics.

The Changing Role of Education in the New Era of Energy

To say that the next generation of workers and leaders in our industry will be confronted by challenges unlike any we have known before is likely an understatement. For the foreseeable future, the list below provides a glimpse of what lies ahead. - An industry whose engineering and scientific foundation are still valid and necessary after 100 years but whose aversion to change has left it struggling to catch up in some areas, most notably in digital transformation (although significant progress has taken place in the past 18 months because of the pandemic) - The paradox of a world that will use fossil fuels to meet a large proportion of its energy demand for the foreseeable future while addressing the negative public and political perception of an industry tied to global climate change - Oil and gas companies morphing into “energy” companies, and petroleum engineers and geoscientists increasingly becoming known as “petrotechnical professionals” (PTPs) - The reality that petroleum engineering roles have expanded to straddle upstream, midstream, and downstream, whereas petroleum engineering programs are mostly geared to upstream and, more particularly, reservoir engineering - The replacement of Baby Boomers with Gen Zers who have an approach to work styles, life, and values generally different from the workforce they will need to lead This labyrinth of challenges, which is raising anxiety and questions about the future of petroleum engineering (PE) education, generated much interest and numerous ideas in the “Future Leaders’ Challenges and Educational Road Map” technical session at the 2021 SPE Annual Technical Conference and Exhibition (ATCE) in September. The papers in the session focused on what academia (and industry) can do to nurture the leaders of the future. A common thread was the need to enable students to not only sur-vive but also thrive as they transition into an evolving industry. The authors discussed issues they believe academia can control and govern—i.e., upgrading education and restructuring academic units—and issues such as demand changes, oil prices, and world politics that are beyond academia’s control. They also expressed agreement that certain elements within teaching and learning practices need periodic modifications—and sometimes serious paradigm shifts or even radical changes. Trends: What’s New (or Not) Paper SPE 205964 asked a rhetorical question, “Is it the end of an era or a new start?” Tayfun Babadagli, professor of petroleum engineering at the University of Alberta, pointed out that beginning with the first publication of an article on PE education in 1937, periodic reviews and evaluations—generally corresponding to industry downturns and drops in enrollment—have questioned whether PE programs should be removed from universities or restructured, depending on local conditions and industry needs. Following the 2014 crisis and a sharp decline in PE enrollments, several SPE papers suggested modernization options and changes in education that included options for local needs in certain geographic areas, field-based education, use of visual tools, and information technologies for smart wells and fields at a graduate (MSc) level. Inclusion of training in geothermal engineering was suggested in 2015. In the past couple of years, digital information sciences and new applications of PE sciences and subsurface storage and groundwater hydrology have been suggested.

Pilot Development of a Critical Food Safety Message Visual Communication Tool for Farmers’ Market Vendors

Farmers’ markets are popular sources of fresh and ready-to-eat foods for consumers in the United States. However, research indicates that food safety practices of vendors and their employees serve as a concern for customers. This pilot study focused on assessing a visual-based, minimal-text educational tool that was disseminated to farmers’ market vendors and employees (n = 27) in Iowa. The tool was evaluated using a post-intervention survey of vendors’ and employees’ knowledge of food safety practices and their attitudes towards the educational tool. The results did not show a statistically significant increase in attitude and knowledge scores of farmers’ market vendors and employees for participants that reported seeing the food safety tool versus those that did not. However, participants did respond favorably to the food safety tool’s informative content and visual format; many indicated an interest in using the tool in their stalls in the future. The results suggest that farmers’ markets vendors and employees feel favorably towards the use of visual tools in the communication and promotion of safe food handling practices.
