Authors: Buryndin Victor , Artyemov Artyem , Savinovskih Andrei , Krivonogov Pavel , Krivonogova Anna
Published: January 2022

Introduction. Agriculture produces a lot of plant and food waste that is highly biodegradable. In order to recycle this waste and use it in the production of new materials, we need to find effective ways to increase their resistance to biodegradation. We aimed to study the biostability of binder-free wood and plant plastics, as well as to find an optimal method of their antiseptic protection.

Study objects and methods. Our objects of study were binder-free plastics based on sawdust, wheat and millet husks. To determine their biostability, we exposed them in active soil for 21 days and analyzed their physical and mechanical properties. Also, we examined the effects of several methods of antiseptic treatment on the samples’ strength, water resistance, and biodegradation.

Results and discussion. All the wood- and plant-based samples showed low biostability. Exposure in active soil caused significant morphological and structural changes, as well as impaired the samples’ physical and mechanical properties, especially those of the plant-based plastics. Their resistance to biodegradation was significantly determined by the type of filler or antiseptic, as well as by the method of antiseptic administration. Whether added to the press mixture or applied to the surface, the antiseptics changed the samples’ physical and mechanical properties. Among the antiseptics used, copper sulfate showed the best effect when introduced directly into the sawdust press mixture. It ensured the lowest decrease in flexural strength, but increased hardness, water absorption, and swelling. The wheat- and millet-based plastics protected with copper sulfate showed an increase in strength indicators, but lower water resistance.

Conclusion. The antiseptic protection of binder-free wood and plant plastics affects a number of their physical and mechanical properties and therefore should take into account the expected conditions for their performance.

Many studies had examined writing strategies in ESL context. However, very few studies examined writing strategies by university students within foreign language learning contexts in Indonesia. Considering that reason, the researcher conducts a survey in EFL context focusing on writing strategies mostly used by 126 students enrolled in essay writing class. This study was conducted by using quantitative method, survey design, and English Writing Strategies Inventory (EWSI) questionnaire as the instruments. The result of this study shows that the predominant learning style of the students are determining the purpose and reading some materials related to the topic before start to write, checking the logical flow through paragraph when writing, and reviewing the writing to look for and correct grammatical errors after writing. It also found that the tendency of students to use EWSI is categorized as high since the frequency of strategy use in each category is high.
Multimodality Imaging Evaluation in Coronary Artery Disease
Authors: Fuji Rahimah Anna
Published: January 2022

Non-invasive imaging modalities are fundamental in evaluating and managing patients with known or suspected coronary artery disease (CAD). Multimodality cardiac imaging procedures detect the presence of CAD and guide clinical decision-making. Combining anatomical and functional imaging modalities would enable a more thorough characterization of obstructive CAD. When selecting an imaging test, one must consider the many factors that interact in the development of chronic CAD and acute coronary syndrome (ACS). The clinical presentation, baseline characteristics of the patient, as well as the clinical center's local availability and expertise will determine the preferred imaging technique to confirm the diagnosis of ACS or chronic CAD. Diagnostic testing is most useful and recommended in patients with chronic coronary syndromes (CCS) when the likelihood is intermediate. The preferred options are coronary computed tomography angiography (CTA) or stress tests, but patients may be referred directly for invasive coronary angiography (ICA) if the likelihood of CAD is very high. The primary goal of the initial diagnostic evaluation in patients with suspected ACS is to confirm ACS and rule out the other most common life-threatening conditions, such as acute pulmonary embolism (PE) or acute aortic syndromes (AAS). Non-invasive imaging is essential in the differential diagnosis of ACS and frequently necessitates multimodality imaging. Cardiac magnetic resonance (CMR) is the most helpful imaging test in diagnosing myocardial infarction with non-obstructed coronary arteries (MINOCAs), and it can detect or rule out other cardiac causes of troponin rise.
PROGNOSTIC VALUE OF RESIDUAL SYNTAX SCORE COMBINED WITH ACEF SCORE IN ACUTE CORONARY SYNDROME PATIENT AFTER PERCUTANEUS CORONARY INTERVENTION IN SAIFUL ANWAR HOSPITAL, MALANG
Authors: Prastya Wikananda Adhika , Saifur Rohman Mohammad , Kurnianingsih Novi , Widito Sasmojo , Rizal Ardian
Published: January 2022

Background : Percutaneous coronary intervention (PCI) is one of the revascularization options in patients with clinical acute coronary syndrome (ACS) who often have multiple and complex vascular lesions. So, the decision to complete revascularization is still a topic that is widely explored to reduce the rate of rehospitalization and reinfarction. This study aims to determine the predictor value of rehospitalization and reinfarction events that can be used in ACS patients undergoing IKP using coronary angiography parameters with residual SYNTAX scores and clinical parameters using ACEF scores. Method : The study was cohort prospective with the inclusion criteria being all ACS patients who underwent PCI in RSUD Dr. Saiful Anwar Malang from January 2017 to July 2021. All patients underwent IKP and underwent coronary angiography evaluation after IKP with a residual SYNTAX score (rSS) and divided into categories into rSS≤8 and rSS>8. All patients underwent laboratory examination of serum creatinine and post-PCI echocardiography, and an ACEF score was obtained (ACEF score = age/left ventricular ejection fraction + 1 [if serum creatinine >2 mg/dl]). Research subjects will be followed up for at least 1 year related to the incidence of post-PCI rehospitalization and reinfarction. Results : From a total sample of 209 patients, it was found that the residual SYNTAX score data had the most significant predictive factor for the occurrence of rehospitalization at 1 year after PCI (OR 6.14 [95% CI, 1.92-1967]). At the value of rSS > 8, (AUC 0.750 [95% CI, 0.682-0.818], p 0.001) has a good predictive value for the occurrence of rehospitalization. However, combining with clinical parameters using the ACEF score provides a better predictive value. This study shows that the combination of rSS>8 and ACEF score>1.2 provides a better predictive value (AUC 0.884 [95%CI, 0.832-0.936) for the incidence of rehospitalization in post-PCI ACS patients. Conclusion : Acute coronary syndrome patients with residual SYNTAX scores > 8 and ACEF scores > 1.2 had a strong predictive value for rehospitalization events 1 year after PCI. The use of the combination of these two scores is expected to be a clinical guide to obtain the degree of completeness of revascularization in ACS patients.
The Gap Between Self-Rated Health Information Literacy and Internet Health Information-Seeking Ability for Patients With Chronic Diseases in Rural Communities: Cross-sectional Study (Preprint)
Authors: Wang Zhuoxin , Fan Yanyan , Lv Hekai , Deng Shanshan , Xie Hui , Zhang Li , Luo Aijing , Wang Fuzhi
Published: January 2022

BACKGROUND

The internet has become one of the most important channels for residents to seek health information, particularly in remote rural areas in China.

OBJECTIVE

In this study, we aimed to explore the gap between self-rated health information literacy and internet health information seeking ability for patients with chronic diseases in rural communities and to preliminarily evaluate their barriers when seeking health information via the internet.

METHODS

Residents from rural communities near Bengbu City and with chronic diseases were included in this study. A self-rated questionnaire was used to evaluate their health information literacy, 3 behavioral competency tasks were designed to preliminarily evaluate their ability to seek health information on the internet and semistructured interviews were used to investigate their barriers to obtaining health information via the internet. A small audiorecorder was used to record the interview content, and screen-recording software was used to record the participants’ behavior during the web-based operational tasks.

RESULTS

A total of 70 respondents completed the self-rated health information literacy questionnaire and the behavioral competence test, and 56 respondents participated in the semistructured interviews. Self-rated health information literacy (score out of 70: mean 46.21, SD 4.90) of the 70 respondents were moderate. Although 91% (64/70) of the respondents could find health websites, and 93% (65/70) of the respondents could find information on treatment that they thought was the best, 35% (23/65) of respondents did not know how to save the results they had found. The operational tasks indicated that most articles selected by the respondents came from websites with encyclopedic knowledge or answers from people based on their own experiences rather than authoritative health information websites. After combining the results of the semistructured interviews with the DISCERN scale test results, we found that most interviewees had difficulty obtaining high-quality health information via the internet.

CONCLUSIONS

Although the health information literacy level of patients with rural chronic disease was moderate, they lack the ability to access high-quality health information via the internet. The vast majority of respondents recognized the importance of accessing health information but were not very proactive in accessing such information.
A 6P framework for engaging consumers in focus group discussions to identify needs, experiences, and expectations with digital health solutions (Preprint)
Authors: Hitige Nadeesha Pathiraja Rathnayaka , Song Ting , Houston Lauren , Smith Natalie Anne , Probst Yasmine , Bliokas Vida , Yu Ping
Published: January 2022

BACKGROUND

Focus group discussions (FGDs) have been used as an effective method to capture consumers’ needs, experiences and expectations for the design of future digital health solutions. However, engaging consumers in FGDs is challenging. To date, there is little guidance for the best practice of moderating FGDs.

OBJECTIVE

This study describes the development of a 6P framework for effectively engaging consumers in FGDs to identify their needs, experiences and expectations for future digital health solutions.

METHODS

A 6P framework – prototype, people, protocol, place, parity and parallelism – for consumer engagement in FGDs was developed by a multidisciplinary team via synthesizing the evidence in the literature. The 6P framework was implemented in two FGDs at a hospital in South-West New South Wales, Australia. Patients with obesity (35kg/m2) who were undergoing weight-loss treatment at the hospital were recruited using purposive sampling. Discussions collected user needs, experiences, and expectations with a prototype mobile health app to support self-management of obesity. The FGD recordings were transcribed verbatim and content analysis was conducted.

RESULTS

Twelve adult participants (5 men, 7 women) participated in two FGDs. The well-prepared prototype (a mHealth app), people (developing team, moderator, observers, and technical assistants), protocol (interview guide, plan and handout), and place (physical and virtual friendly one) enabled the participants to actively engage in FGDs to express their needs, experiences and expectations. Participants expressed positive thoughts about the overall usability and usefulness of the app. They provided suggestions for further improvement of the app in terms of information quality (the presence of some irrelevant, incomprehensible, or incomplete information) and system quality (difficulty of using app functions). Participants also expressed an expectation to see more personalized graphical designs that are easy to comprehend. The moderator used the two techniques – parity and parallelism, to control the dominant participants and encourage silent participants, so that they can express their opinions as objectively as possible.

CONCLUSIONS

Following the 6P framework to moderate FGDs is conducive for consumers to understand the discussion topic, engage in peer interaction about a prototype and relate the interactional experience with their previous digital solution usage experiences. The framework provides insight for managing dominant participants and eliciting further functions. It also enables consumers to effectively reflect, understand and express their needs, experiences and expectations in digital solution co-design in FGDs.
Delivery of a Mental Health Intervention for Chronic Pain Through an Artificial Intelligence–Enabled App (Wysa): Protocol for a Prospective Pilot Study (Preprint)
Authors: Gupta Megha , Malik Tanya , Sinha Chaitali
Published: January 2022

BACKGROUND

Patients with chronic pain often experience coexisting, long-term and debilitating mental health comorbidities such as depression and anxiety. Artificial intelligence–supported cognitive behavioral therapy (AI-CBT) interventions could offer cost-effective, accessible, and potentially effective resources to address this problem. However, there is not enough research conducted about the efficacy of AI-CBT interventions for chronic pain.

OBJECTIVE

This prospective cohort study aims to examine the efficacy and use of an AI-CBT intervention for chronic pain (Wysa for Chronic Pain app, Wysa Inc) using a conversational agent (with no human intervention). To the best of our knowledge, this is the first such study for chronic pain using a fully-automated, free-text–based conversational agent.

METHODS

Participants with self-reported chronic pain (n=500) will be recruited online on a rolling basis from April 2022 through posts on US-based internet communities within this prospective cohort. Informed consent is received from participants within the app, and the Wysa for Chronic Pain intervention is delivered remotely for 8 weeks. Outcome measures including a numeric pain rating scale and Patient-Reported Outcomes Measurement Information System–Pain Interference, Generalized Anxiety Disorder–7, and Patient Health Questionnaire–9 questionnaires administered to test the effectiveness of the intervention on reducing levels of pain interference, depression, and anxiety. The therapeutic alliance created with the conversational agent will be assessed through the Working Alliance Inventory–Short Revised instrument. Retention and use statistics will be observed for adherence and engagement.

RESULTS

The study will open for recruitment in April 2022, and data collection is expected to be completed by August 2022. The results for the primary outcomes are expected to be published by late 2022.

CONCLUSIONS

Mental health conversational agents driven by artificial intelligence could be effective in helping patients with chronic pain learn to self-manage their pain and common comorbidities like depression and anxiety. The Wysa for Chronic Pain app is one such digital intervention that can potentially serve as a solution to the problems of affordability and scalability associated with interventions that include a human therapist. This prospective study examines the efficacy of the app as a treatment solution for chronic pain. It aims to inform future practices and digital mental health interventions for individuals with chronic pain.

The Trusting Beliefs of Users and the Intention to Continue Making Purchases via Social Commerce
Authors: Susilo Ghina Fitri Ariesta , Rani Utpala , Khotijah Siti Afidatul
Published: January 2022

Introduction/Main Objectives: This study aims to examine the influence of a user’s trusting beliefs on the intention to continue making purchases via social commerce. Indonesia is ranked 4th in the world for the most active online users of social media. Thus, it is necessary to investigate the influence of those variables. Background Problems: Social networks contribute to online trading by providing platforms for social commerce. The author chose the trusting beliefs concept and linked it to online users’ trust in social commerce. Novelty: Trusting beliefs variables are fundamental in shaping online users’ behaviors, but no prior research has investigated the effect of trusting beliefs on the intention to make purchases via social commerce. This study presents new research that provides a comprehensive model related to social commerce. Research Methods: This research uses purposive sampling of people who are required to have social media accounts and who have made purchases via social commerce at least once with data taken from surveys. The research uses Structural Equation Modelling (SEM). Finding/Results: This study proves that all trusting beliefs variables are supported and significant, but there is one hypothesis that is not supported (H4). Empirically, this indicates that active users are not necessarily engaging in online shopping using their social media. Conclusion: This study provides insights into the potential role of trusting beliefs driving continuing purchases in the context of social commerce research. We suggest that the sellers need to give customers-to-be more frequent and wider product reviews information so they can get results in terms of stronger product image and motivate them to make purchases via social commerce.

Numerical Investigation of Radiation Effects on MHD Convective Heat and Mass Transfer Flow Past a Semi-Infinite Vertical Moving Porous Plate in the Presence of Chemical Reaction
Authors: Vellanki Nagaraju
Published: January 2022

Abstract: The numerical solutions for heat and mass transfer by laminar flow of a Newtonian, viscous, electrically conducting and heat generation/absorbing fluid on a continuously vertical permeable surface in the presence of a radiation, a first-order homogeneous chemical reaction and the mass flux are considered. The plate is assumed to move with a constant velocity in the direction of fluid flow. A uniform magnetic field acts perpendicular to the porous surface, which absorbs the fluid with a suction velocity varying with time. The Equations of continuity, linear momentum, energy and diffusion, which govern the flow field, are solved by using a Finite Element Method. The results of the velocity, temperature, concentration, skin- friction, Nusselt number and Sherwood number has been discussed for variations in the governing parameters. Keywords: MHD, Radiation, Heat and Mass Transfer, Porous Medium, Unsteady flow, Finite Element Method.

Casa-exílio, palavra-mapa
Authors: Dias Karina , Ferreira Luciana
Published: January 2022

O que é o exílio? – esta é a questão que norteia o diálogo entre dois pensamentos. No primeiro, o exílio é entendido como a perda de uma casa, um lançamento no mundo, onde a procura da casa acontece de forma incessante e sem garantias. No segundo, o exílio é vivido como a perda do mundo pela condição de se ter que permanecer dentro da própria casa, portanto, quando o mundo precisa ser percorrido e inventado entre as suas paredes. O texto explora as nuances desses dois pensamentos em diálogo com trabalhos de artistas visuais e, em alguns momentos, na sua relação com a palavra, ora uma palavra exilada, ora uma palavra-mapa.
Xamanismo em fotolivros de Claudia Andujar: Yanomami e Amazônia
Authors: Albuquerque de Moraes Ana Carolina
Published: January 2022

Este artigo propõe-se a analisar a abordagem do xamanismo yanomami pela fotógrafa Claudia Andujar em seus dois primeiros fotolivros, ambos de 1978: Yanomami: frente ao eterno (com Darcy Ribeiro) e Amazônia (com George Love). Em cada livro, são analisados o projeto gráfico, os assuntos dominantes e, sobretudo, o modo como o tema xamanismo é abordado. O viés das análises é sobretudo antropológico, coerentemente com o foco de Andujar na compreensão cultural dos Yanomami. Enquanto, em Yanomami, a abordagem do xamanismo é discreta, em Amazônia, é vigorosa, pela quantidade de imagens dedicadas ao tema e a variedade de recursos visuais utilizados.

The osteopontin released from mesenchymal stem cells (MSC) undergoing
lineage differentiation can negatively influence the expansion of
hematopoietic stem cells (HSCs) in co-culture systems developed for
expanding HSCs. Therefore, minimising the amount of osteopontin in the
co-culture system is important for the successful ex vivo expansion of
HSCs. Towards this goal, a bioengineered 3D-microfibrous matrix that can
maintain MSCs in less osteopontin releasing condition has been developed
and its influence on the expansion of HSCs has been studied. The newly
developed 3D-matrix significantly decreased the release of osteopontin,
depending on the MSC culture conditions used during the priming period
before HSC seeding. The culture system with the lowest amount of
osteopontin facilitated more than 40-fold increase in HSC number in 1
weeks’ time period. Interestingly, the viability of expanded cells and
the CD34+ pure population of HSCs found to be the highest in the low
osteopontin containing system. Therefore, bioengineered microfibrous
3D-matrices seeded with MSCs, primed under suitable culture conditions
can be an improved ex vivo expansion system for HSC culture.

O objetivo deste estudo bibliográfico foi compreender a integração da gestão escolar na rede protetiva e as responsabilidades e funções do gestor diante da percepção de situações de violência contra crianças e adolescentes. O foco foi na gestão escolar democrática com participação efetiva dos que atuam nesse contexto, e ainda na eficiência, sigilo e otimização necessários para proceder à notificação dessas situações ao conselho tutelar. Assim, buscou-se conhecer se existem instrumentos informatizados específicos para que possam auxiliar a gestão escolar em suas funções. Este estudo mostra que a gestão escolar democrática, além de promover a melhoria da qualidade da educação, pode contribuir para a proteção de alunos contra situações de violência. Estudos futuros no sentido de criação e implementação de instrumentos informatizados podem auxiliar o gestor escolar a cumprir a função da escola na rede protetiva e a estabelecer canais de comunicação eficientes e seguros com o conselho tutelar.

Authors: Oliveira Sidmar da Silva
Published: January 2022

O objetivo desta pesquisa é compreender os elementos dificultadores e os caminhos possíveis para efetivação da gestão escolar democrática em Monte Santo-BA. Trata-se de um estudo netnográfico, de abordagem qualitativa, que parte da seguinte questão: quais os elementos dificultadores e os caminhos possíveis para efetivação da gestão escolar democrática em Monte Santo-BA? Para atingir o objetivo proposto e responder à questão central, realizou-se uma entrevista semiestruturada com três profissionais da educação que atuaram na direção de escolas por indicação política e por processo eletivo, e traçou-se uma discussão das aspirações e crenças dos sujeitos com os estudos teóricos sobre gestão escolar democrática e proposições impressas nos diplomas legais. Os resultados apontam que a eleição para gestores escolares é um mecanismo fundamental para promoção da gestão escolar democrática que dialoga com os anseios dos interlocutores da pesquisa, mas ainda depende da vontade política dos governantes locais para ser efetivada.

Published: January 2022

O presente estudo mostra registros que os professores fazem sobre suas práticas, vivências diante do impacto das mudanças na política educacional. O interesse por refletir sobre o ideário dos docentes iniciou a partir de uma nova práxis em que um dos entraves da aprendizagem dos alunos está relacionado aos precários conhecimentos acadêmicos do professor, com discrepâncias entre teoria e prática, visto que a teoria é importante, mas sozinha é insuficiente para a sala de aula. O objetivo do estudo foi investigar, através da literatura, a necessidade de alinhamento entre teoria e prática. Os procedimentos metodológicos utilizados para a coleta de dados incluíram revisão da literatura, observação in loco e entrevistas semiestruturadas aos docentes. As informações coletadas foram analisadas qualitativamente, sob a ótica dos autores que orientaram a fundamentação teórica. Concluiu-se que compete ao educador perceber características do discente e sua interação com o ambiente.

Published: January 2022

Este artigo é parte de uma pesquisa de doutorado que tem por objeto de estudos, o planejamento das atividades escolares para o período de ensino remoto emergencial implementado em 2020, em decorrência da pandemia da Covid-19, no âmbito das redes municipais de ensino dos municípios de uma microrregião do interior paulista. O objetivo da pesquisa é compreender como esse momento foi pensado, identificando, descrevendo e analisando estratégias de ensino remoto, dificuldades, ações bem-sucedidas e inovações que essa situação propiciou a esses municípios. Para tanto, foi realizada uma pesquisa bibliográfica e documental acerca do ensino remoto, além de uma pesquisa de campo com as equipes pedagógicas que o planejaram em seus municípios. O estudo aqui apresentado destaca a análise descritiva dessa pesquisa, que se mostra relevante pela necessidade de registro das experiências vivenciadas nesse momento, as quais podem, se bem-sucedidas, ser aproveitadas no pós-pandemia para melhorar a qualidade da educação.
Wise political education: characteristics, principles and efficiency
Authors: Mahdi Naderi  , Pirani Shohreh
Published: January 2022

Political education means preparing citizens to accept social roles and perform political duties in society. Wise political education is one of the educational models that is rooted in the philosophical tradition of ancient Greece and has been considered by thinkers in different historical periods. In this educational model, the institutionalization of political and social values and norms is followed in three individual, family and social areas of education. In this process, the physical and mental education of individuals begins from childhood and they are taught political and social skills and awareness on the path to development. Teaching moral virtues and avoiding moral vices is the basis of wise political education. The institution of the family has the task of institutionalizing values and norms such as love, affection, courage, friendship, cooperation and rule of law in children. And in the process, individuals are prepared to accept and play political and social roles.
Saberes experienciais da docência em matemática: tecituras formativas no cotidiano da profissão docente
Authors: Vieira André Ricardo Lucas , Silva Fabrício Oliveira da , Dias Alfrancio Ferreira
Published: January 2022

O presente artigo objetiva compreender como o/a docente de matemática produz um saber experiencial que é articulado aos percursos de suas próprias histórias de vida, de formação, bem como das necessidades de desenvolver estratégias de ensino que se articulem às necessidades formativas dos/as discentes. O estudo é de base qualitativa e ancora-se na abordagem (auto)biográfica, em que o/a professor/a fala de si, de seus movimentos profissionais e de ações educativas, imprimindo em sua narrativa os sentidos que ele/ela próprio/a produz ao narrar. O dispositivo de recolha de informações foi a entrevista narrativa desenvolvida com três professores/as de matemática que atuam no Ensino Médio. Os resultados evidenciaram que o ensino de matemática, que se efetiva numa relação dialógica a partir das vivências dos/as estudantes, logra maior condição de gerar aprendizagens. A contextualização a partir das vivências dos/as discentes favorece, a estes/as, maior êxito da aprendizagem da matemática e, de igual modo, produz significâncias sobre a matemática na vida dos/as estudantes.
Excertos da BNCC: discussão de fundamentos e considerações conceituais
Authors: Lemes Sebastião de Souza
Published: January 2022

Nesse primeiro recorte feito em um estudo amplo com certa profundidade teórica objetiva discutir alguns conceitos trazidos pela BNCC a partir de excertos dos seus fundamentos. O texto procura, por esse caminho e à luz de uma exploração teórica reflexiva, analisar a complexidade desse universo para o fazer pedagógico no cotidiano da escolarização, pois, considera certa incompletude pela distância existente entre a sua formulação idealizada e a realidade estrutural e conjuntural então apresentados para que “tenham assegurados seus direitos de aprendizagem e desenvolvimento, em conformidade com o que preceitua o Plano Nacional de Educação”. Este estudo teórico e exploratório dos conceitos e elementos de narrativa presentes em um “documento de caráter normativo” e com o grau de complexidade instrumental e operacional que se apresenta precisa de indagações e reflexões permanentes sobre sua efetividade, do sistema educacional até à unidade escolar.
Designing the mathematics educational process in the context of education metadisciplinarity
Authors: Rymanova Tatyana E. , Chernousova Natalia V. , Melnikov Roman A.
Published: January 2022

The article is devoted to one of the current issues – the problem of educational process design. Among the Russian educational space innovations, a special place belongs to the metadisciplinary direction, new for domestic pedagogy. Comprehension of the metadisciplinarity category both in the theoretical aspect and applied from the position of the modern view becomes especially important. To some extent, the complexity of the problem is determined by the ambiguous translation of the prefix “meta.” Recently, there have been many studies devoted to metadisciplinarity. The analysis of scientific works on this problem showed no single point of view on this issue. The axiomatic approach is proposed as one of the options for building an educational strategy in the metadisciplinary field. This study aims to show the possibility of using the latter in designing the mathematics educational process as part of implementing the metadisciplinary direction of the educational standards.
