This article is about research done on the ways of using visuals in teaching introductory mathematics. Research showed that the use of visuals improves the learning of mathematics. However, more research is needed to explore which math concepts need to be addressed, how to choose visuals for that purpose, and how to incorporate them in teaching mathematics. The analysis shows that the effective use of correctly chosen visuals in teaching introductory mathematics positively impacts students’ attitudes toward mathematics, and enhances their learning, engagement, and motivation. Keywords: analytical thinking skills, instructional strategies with visuals, introductory mathematics, student engagement, and motivation

In this paper, we study the arrangement of lines in the euclidean plane constructed from the geometric clique graph generated by the regular -gon. The vertices of this clique arrangement are located on finite concentric circles that we call orbits. We focus especially on the number of orbits and the number of vertices inside and outside the regular -gon. Combinatorics in finite sets of quadruplets of integers provide information on the way the orbits are distributed. Next, using cyclotomic fields, we give galoisian properties of the radii of the orbits and their cardinalities. Keywords: arrangement of lines in the plane, cyclotomic fields, geometric graphs, Galois theory

A high occurrence of greenish soybean seeds in crops is an issue, these types of seeds have low physiological quality, which can generate seedlings with anomalies, if destined for processing in industries, the presence of chlorophyll is undesirable, requiring additional processes for its removal. This work aimed to evaluate the differentiation of mature and greenish soybean seeds, illuminated with red laser, green laser, red LED, and fluorescent lamp, using image processing. Images of mature and greenish soybean seeds were captured at a resolution of 340x480 pixels, illuminated with red laser, green laser, red LED, and fluorescent lamp. Subsequently, the averages of the gray levels of each image were obtained in the red, green, blue channels and in images converted to grayscale 8-bit. The data were submitted to tests of variance after gray level for image classification. And a validation presented results of 97% of hits for red laser, 94% for fluorescent light and 93.5% for red LED, all in red channel. Keywords: seed classification, agricultural automation, soybean seed quality, computer vision

The modeling of superdense matter is an interesting research area and in the last decades, such models allow explain the behavior of massive objects as neutron stars, quasars, pulsars and white dwarfs. Taking local anisotropy into consideration, in this paper we present a new classes of solutions for the Einstein´s field equations in a spherically symmetric spacetime under the influence of an electric field considering a quadratic equation of state with a particular form the metric potential that depends on an adjustable parameter. The obtained solutions can be written in terms of elementary functions, namely polynomials and algebraic functions. The graphs generated show that physical variables such as metric potentials, radial pressure, energy density, charge density, anisotropy, radial speed sound are consistent with realistic stellar models. The results of this research can be useful in the development and description of new models of compact structures. Keywords: quadratic equation of state, Einstein-Maxwell system, metric potential, adjustable parameter, compact structures

In the years 2015–2018, the Italian Ministry of Education, University and Research and the Italian Ministry of Defense proposed the joint initiative "Space for Your Future. The ISS: Innovatio, Scientia, Sapientia" in partnership with the Italian Space Agency. It was a competition addressed to secondary school students and aimed at developing innovative experiments to be conducted on the International Space Station, whose acronym (ISS) is the same of the Latin words "Innovatio, Scientia, Sapientia". Regardless of the odds of winning, "Space for Your Future" became a successful STEM educational project implemented in numerous schools. We illustrate how that Astronomy contest fostered a valid constructivist learning, a fruitful participatory science, and vast scientific research. We discuss, in particular, the activities of two teams of pupils from the Scientific High School "Giovanni Battista Grassi" in Latina (seat of the Planetarium "Livio Gratton") who participated within the thematic area No. 3 "Test the Sciences in Space". They all worked on chemical tests, suitable for the ISS microgravity, under the tutoring of Francesco Giuliano (Province Manager of the IYA 2009 and the IYC 2011 in Latina). The key reference is a talk given in the 104th annual congress of the Italian Physical Society at the University of Calabria (September 17–21, 2018) together with an invited lecture held in the 13th European Researchers’ Night by Frascati Scienza (September 28, 2018).

In the context of the Corporate Sustainability Reporting Directive (CSRD) that has been passed by the EU Parliament in November 2022 and which fundamentally changes the ways how companies reporting are made and the type of sustainability reporting made by the companies targeted by the directive, in this paper it is analyzed and examined, according with the forerunning directive, Non-Financial Reporting Directive (NFRD), which have been made compulsory by the European Union starting with year 2014, the improvements that have been effectively made in the emissions of greenhouse gases by the largest 6 companies in terms of revenue that operate primarily in energy, oil and gas industries (either by upstream, midstream or downstream sectors) and are of continental European origins. In this article are highlighted the economical efforts of combating the greenhouse gases (GHG) and the efficiency of the measures taken, both individually and collectively by the aforementioned conglomerates. It is also discussed the economic efficiency, both cumulative and separately for each of the analyzed companies. As well, an overview of the reduction importance of greenhouse gases is presented by exposing the environmental measurements since first being reported at a scientific level.

Transfer Functions relate the output or response of a system such as a filter circuit to the input or stimulus . The response can be measured; the is the unknown. Solving the World Formula not only explains how analog images and voice can be digitally stored, but also many methods and techniques such as Big Data and Artificial Intelligence. For linear functions between vector spaces, the Eigenvector Method makes calculating a solution easy, if it exists. Numerical algorithms are available for solving. Thus, the method is suitable for teaching students who are interested in the foundations of science. However, the system must meet certain conditions to make the eigenvector method applicable. The Theorem of Perron-Frobenius defines these conditions. Keywords: transfer functions, big data, world formula, Eigenvector method, theorem of Perron-Frobenius

This research explores a contemporary outsider view of Belfast, through the eyes of Generation Z visiting college students, in relation to how three United Nations Sustainable Development Goals (UNSDGs) are carried out (Good Health and Well-Being, Climate Action, and Peace, Justice, and Strong Institutions). To learn through firsthand accounts, the researchers utilized ethnographic and phenomenological methods, as interacting with locals to gather community inputs, surveying different groups in the city, recording quotes said by citizens and displayed at billboards, and applying personal sensory experiences. It was found that a political deadlock plays a major role in the lack of steadiness. The research shows that Northern Ireland has progressed in many ways but also that it is still being limited by inefficient governmental practices. The rather brief time spent in Belfast barely allowed the researchers to feel and sense its atmosphere but deterred them from making recommendations.

Aiming to bridge the gap in the field of computational thinking and computing education, this study examines preservice teachers’ knowledge of and self-efficacy related to CT assessment. It also develops a reliable instrument to understand the construct of teacher assessment of CT. Specifically, the research questions focus on investigating the extent of preservice teachers’ knowledge and level of self-efficacy of CT assessment, and identifying the difference between demographic variables on teacher knowledge and self-efficacy related to CT assessment. Adopting a cross-sectional survey design, the participants were 182 preservice teachers. Both descriptive statistics and Exploratory Factor Analysis were used to analyze the data. The results show that the preservice teachers know little about how to use CT assessment to help students, and they believe they know even less about using specific assessment techniques to accomplish assessment.
