The theorems about traces and extensions for functions from Nikolsky-Besov spaces with generalized mixed smoothness

The theory of embedding of spaces of differentiable functions studies important relations of differential (smoothness) properties of functions in various metrics and has wide application in the theory of boundary value problems of mathematical physics, approximation theory and other fields of mathematics. In this article, we prove the theorems about traces and extensions for functions from Nikolsky-Besov spaces with generalized mixed smoothness and mixed metrics. The proofs of the obtained results is based on the inequality of different dimensions for trigonometric polynomials in Lebesgue spaces with mixed metrics and the embedding theorem of classical Nikolsky-Besov spaces in the space of continuous functions.

Comparative Analysis of ARIMA and Artificial Neural Network Techniques for Forecasting Non-Stationary Agricultural Output Time Series

With the vast popularity of the deep learning models in the engineering and mathematical fields, Artificial Neural Networks (ANN) have recently attracted significant research applications in agriculture, economics, informatics and finance. In this paper, we use a deep learning method to capture and predict the unknown complex nonlinear characteristics of agricultural output based on autoregressive artificial neural network, using Nigeria as a case study. Using the proposed model, shocks in agricultural output is analyzed and modeled using data obtained for a period of forty years (1980-2019), and compared with analyses obtained from the autoregressive integrated moving average model (ARIMA). This result is significant because it justifies the superiority of the hybrid ANN model over the traditional Box-Jenkins methodology for forecasting non-stationary time series. The empirical results show that the proposed autoregressive ANN model achieves an improved forecasting accuracy over the traditional Box-Jenkins ARIMA method. It is further proposed that various types of artificial neural networks would be useful in forecasting and solving relevant tasks and problems widely defined in global agricultural production.

Advanced technology in education provides various facilities to enhance students’ learning. The evolution of technology has become an integral part of sustaining life, especially in education. The technology in education develops and continues its development with innovative learning approaches to sustain the needs of the 21st-century learning environment. The transformation in the educational field takes out the existence of a new strategy that is flipped classroom learning approach. A flipped classroom is a learning approach that is a type of blended learning that involves face-to-face and online learning instruction. The flipped classroom is a pedagogical approach in which learning activities that have traditionally taken place inside the classroom occur outside the classroom and vice versa. Flipped classroom provides an interactive learning environment where teachers guide students as they engage actively in the subject matter. Thus, this paper will review the recent literature regarding the potential of flipped classroom technology in education and explore its advantages and challenges. The review describes the potential of the flipped classroom in various fields of education, including Chemistry, Physics, Mathematics, Biology, and Civics at secondary school or high school level. Searching of the literature was obtained from several databases by using certain Boolean queries when searching the keywords. Ten papers were selected according to the specific criteria. This paper concludes the advantages and challenges during the implementation of FC. The advantages of flipped classsroom are increased students’ motivation during learning processes, providing active learning, increasing learning perception, increasing learning engagement, enhancing knowledge, increasing teacher-student interaction, increasing peer interaction, enhancing creativity and helping to improve students’ achievement and performance. The challenges of FC are the time-consuming for teachers to prepare the learning materials, lack of teachers’ technical skills to produce learning videos, lack of students’ motivation to watch the pre-class video, and the difficulty of students to understand the contents presented in the learning video. Based on these challenges, this paper provides the literature recommendations that can help to produce effective flipped classroom environments in the future.

Human-Centered Approach in New Development Tendencies of Value-Oriented Public Administration: Potential of Education

The main technological areas of improvement through the formation of the best human qualities within the framework of a new humanism which is connected with the promotion of the self-realization of an individual simultaneously in the interests of society and humanity, are proposed. The fact of the primacy of man and his activity in the appearance of threats to the development of mankind is becoming more and more indisputable. In the context of globalization, it makes sense to consider the relevance of the problem of improving human capital in three aspects of the social development of mankind: planetary; national; personal. The technique essence of the formation of the best human qualities in the education system based on the digitization of the educational process at educational institutions with the help of factor-criterion qualimetry from the field of fuzzy mathematics is revealed. It is emphasized that all of the above in its totality determines the New Strategy for the Improvement of Human Capital in the interests of both an individual and society and all of the humanity. This strategy is implemented thanks to the implementation of effective management in the education system by displacing the current culture of administrative pressure (CAP). Its gradual replacement with the system management culture (SMC) according to the final results is carried out through measurements of these results and their interpretation in the form of certain indices. It is positive dynamics of these indices that determines the resulting educational activity.

Evaluation of the Effectiveness of Realistic Mathematics Education: Meta-Thematic Analysis / Gerçekçi Matematik Eğitiminin Etkililiğinin Değerlendirilmesi: Meta-Tematik Analiz

This study was aimed to determine the effectiveness of the Realistic Mathematics Education (RME) used in mathematics teaching. For this aim, studies including participant views on the use of RME were examined in accordance with the PRISMA flow chart and in line with the inclusion criteria determined by the researcher. These criteria were determined as “studies involving the RME application in the field of mathematics, studies conducted between 2012-2022 (last ten years), studies containing qualitative participant views, and studies published in Turkish or English”. A total of 146 studies reached were evaluated according to these criteria, and the remaining 24 studies were included in the meta-thematic analysis. The data on the examination of the use of RME were obtained by the document analysis and analyzed by the content analysis through the use of the Maxqda-11 qualitative data analysis program. The themes that emerged from the analysis were: contribution to the delivery of course, making connections with daily life, contribution to the attitude towards mathematics and contribution to thinking skills. These themes and codes were interpreted separately. In addition, direct quotations from the sources were included to support the presentation of the relevant themes and codes. Analysis results showed that RME has contributed positively to math teaching in many ways. On the other hand, the negative contribution of RME to math attitude emerged with codes such as inefficient use of time, noise, negative group synergy and intra-group conflicts. It is suggested to include more RME practices in order to adopt the principle of "mathematics for all" on Freudenthal's discourse, to develop a positive attitude towards mathematics and to associate it with real life.

Opinions of Novice Mathematics Teachers on Improving the Teacher Induction Programme

Teacher induction programs are education systems designed to improve the knowledge, skills and mental structures of novice teachers. If we look at the induction program in Turkey, in March and October 2016, some radical changes took place in the induction process. With this change, the number of studies on the induction process has increased, and studies reflecting the views of novices on the induction program, regardless of field, have taken their place in the literature. However, as it is known, the field-specific needs and problems of novice teachers in different fields may change. In particular, it has been revealed that novices in the field of science and mathematics have more special needs than novices in other fields. Based on this idea, in this study, the views of novice mathematics teachers on the development of the induction program are discussed. For this purpose, 27 novice mathematics teachers who have just completed their induction processs were asked to make suggestions for the improvement of the induction program, taking into account their own experiences. The case study method was used in the study and the data were analyzed using the content analysis technique. Findings are presented in the form of MAXQDA maps, and quotations from teacher responses are also included. It has been revealed that the majority of novice mathematics teachers want support for the field. In addition, they stated that there should be mentors from the same field as the novices in the school and in the region, and that opportunities should be offered for them to develop themselves.

Characteristics and Recommendations for the Virtual Role Model Visit - Based on a Literature Review.

In recent years, several role-modelling initiatives have been testing and exploring the use of digital technologies to facilitate young people's encounters with role models in the science, technology, engineering, and mathematics (STEM) fields. The aim of this article is twofold. Firstly, through a literature review, the article aims to provide an overview of how digital technologies have been used to facilitate the students' encounters with STEM role models. The literature review shows how the use of digital technologies (1) enables scaling so that more young people can have access to role models, (2) enables the role models to show authentic work tasks and environments through virtual field visits, allowing pupils to closely examine the work processes in production companies, the laboratory, or in geographically remote locations, (3) opens up new opportunities for young people to interact and become involved, both through synchronous and asynchronous communication. The second aim of the article is to present, based on the knowledge gained from the literature study, a framework of eleven recommendations for the design of future virtual role model visits.

Investigating the challenges faced by female students in STEM courses: case study of a traditional South African University

The paper investigated the challenges faced by female students enrolled in the Science, Technology, Engineering and Mathematics (STEM) field of study. The social cognitive theory (SCCT) was employed to examine the role played by the environment, goals, behaviour, and self-efficacy factors of female students studying towards Engineering and Information Technology degrees at a traditional South African university. The study examined the interdependencies between these four factors and their role in female students’ success in STEM courses at the university. The finding revealed that female students possess the selfefficacy required to excel in their studies, despite overt or covert hostilities and other challenges they face during their study. The data analysis indicate that female students need the support of their families in achieving their goals. The fear of disappointing parents or family members if they fail to obtain their qualifications seem to be a key motivation to female students in STEM courses. It is recommended that all stakeholders be positively involved in ensuring that female students in the STEM fields get the needed support. Such support, in tandem with their self-efficacy, outcome expectations and goal setting, will ensure that they overcome obstacles and are adequately equipped to realise their dream of achieving qualifications in this critical segment of the economy.

Forecasting of Winter Wheat Yield: A Mathematical Model and Field Experiments

An increase in world population requires growth in food production. Wheat is one of the major food crops, covering 21% of global food needs. The food supply issue necessitates reliable mathematical methods for predicting wheat yields. Crop yield information is necessary for agricultural management and strategic planning. Our mathematical model was developed based on a three-year field experiment in a semi-arid climate zone. Wheat yields ranged from 4310 to 6020 kg/ha. The novelty of this model is the inclusion of some stochastic data (weather and technological). The proposed method for wheat yield modeling is based on the theory of random sequence analysis. The model does not impose any restrictions on the number of production parameters and environmental indicators. A significant advantage of the proposed model is the absence of limits on the yield function. Consideration of the stochastic features of wheat production (technological and weather parameters) allows researchers to achieve the best accuracy. The numerical experiment confirmed the high accuracy of the proposed mathematical model for the prediction of wheat yield. The mean relative error (for the third-order polynomial model) varied from 1.79% to 2.75% depending on the preceding crop.

The role of media professionals in perpetuating and disrupting stereotypes of women in Science, Technology, Engineering and Math (STEM) fields

Women continue to be underrepresented in the Science, Technology, Engineering and Mathematics (STEM) fields despite efforts to enhance interest and persistence at all levels in the educational pipeline. The “chilly” climate documented for girls and women in STEM exists within a broader communication climate established and reinforced by media professionals. The present study examined the role of media professionals in perpetuating stereotypes of women in STEM through two approaches (1) conducting interviews with seventeen STEM women about their engagement with media professionals and (2) surveying 105 media professionals about their stereotypes about science and scientists. STEM women report positive interactions with the media despite incidents of unprofessionalism, dissonance between the processes and pace of science vs. the media, an undercurrent of issues pertaining to gender and other forms of representation, and an ethical responsibility to engage with media. The survey of media professionals revealed persistent stereotypes about scientists across both genders, and these stereotypes were more pronounced among those who engaged with science as part of their job, particularly among those working in entertainment and advertising and those working outside of journalism and social media. To establish greater equity in STEM fields and the knowledge pipeline, communication scholars must investigate the role of media professionals in this process and consider best practices to disrupt media stereotypes about STEM women.

The results are displayed in a short amount of time and in certain cases provide a comprehensive look at the developments and standing of the GeoGebra literature by affiliation from Indonesia, including information on authors, institutions, nations, and author keywords. For the purpose of clarity, the author's own keywords are the only ones used in the data analysis in this study. However, no R programming language library currently exists that can handle this issue.

A Framework for Incorporating the “Learning How to Learn” Approach in Teaching STEM Education

The importance of STEM subjects for the purposes of scientific and technological development has gained global momentum. Yet, there are various obstacles to applying a STEM education in the context of preparing students for a scientifically and technologically advanced society. There has been little research on how engineering can be incorporated into the elementary school curriculum. This study, thus, provides a systematic review of the learning techniques and structured framework that are used to support learning in the fields of science, technology, engineering, and mathematics (STEM). It also aids in identifying students’ shifts in interest toward STEM subjects, as well as their desire to pursue future STEM-based careers. This study makes use of a systematic literature review of high-impact journals with a Q1 or Q2 ranking. It was also found that there are hurdles in regard to the teaching approach that is used for STEM subjects. This suggests that there are numerous opportunities that can be exploited by educators in their hunt for a better STEM teaching approach. Finally, researchers must create features that enable students to gain fundamental competencies within the STEM disciplines. Future applications must include the experimental support for the purposes of inquiry-based learning activities.
