In this work, the hydrogen bonds and halogen bonds in the complexes between Ysub.2CTe (Y = H, F, CHsub.3) and XF (X = F, Cl, Br, I) have been studied by quantum chemical calculations. We found three ...interesting abnormalities regarding the interactions. Firstly, the strength of halogen bonds increases in the order of IF < BrF < ClF < Fsub.2. Secondly, the halogen bonds formed by Fsub.2 are very strong, with an interaction energy in the range between −199.8 and −233.1 kJ/mol. Thirdly, all the halogen bonds are stronger than the hydrogen bonds in the systems we examined. All these results are against the general understanding of halogen bonds. These apparent abnormal properties are reconciled with the high polarizability of the Te atom and the strong inducing effect of F on the Te atom of Ysub.2CTe. These findings provide a new perspective on halogen bonds. Additionally, we also proposed bonding distance-based methods to compare the strength of halogen/hydrogen bonds formed between different donor atoms and the same acceptor atom.
Abstract According to the World Economic Forum, appropriate education enables indigenous children and adult learners to exercise and enjoy economic, social, and cultural rights. It also strengthens ...their ability to exercise their civil rights so they can influence political policy processes for enhanced protection of their human rights. We contend that STEM education is one of the important components of appropriate education. The concept is modeled after the Science Pathway for Indigenous Communities developed by CSIRO. More specifically we carried out an initial study in Kasepuhan Ciptagelar, whose indigenous knowledge has been studied quite extensively.
I estimate the effect of attending an associate degree in nursing program on nursing licensure. I use student-level academic data for all California community college students, matched to public ...records on all nursing licenses earned in the state. I produce causal estimates using random variation from admissions lotteries at a large nursing program. Enrolling in the program increases the probability of having an active nursing license by 59 percentage points within three years. By seven years the effect is smaller and not statistically significant. I estimate the value of a nursing license as approximately $5000-$6000 per year.
•Community college nursing programs lead to registered nurse licensure.•I use admissions lotteries to estimate the effect of enrolling in the program.•The effect fades over time as lottery losers likely enroll in other programs.•The value of a nursing license is approximately $5000–$6000 per year.
Abstract
Recently, attention is paid to conceptual aspects of STEM or particular usage of specific tools during STEM. This paper is devoted to systemize all digital tools used during STEM classes. It ...is proposed to systemize all equipment into instrumental, computer simulation, and modern ones (VR, AR, and AI and 3d-modelling). It is proved the dominant role of computer simulation and modern instruments during providing STEM classes due to their simplicity and absence of necessity of expensive equipment usage. Using any of the described tools do not guaranty providing STEM, but they can be used as an element of the STEM didactic approach.
One of the key points in sports training is to know exactly when a technical movement needs to be modified, and the best strategies to do it. It has been shown that the interaction with different ...materials and spaces is an adequate strategy to enhance the search for motor solutions in athletes. However, it is also very important to know how an added difficulty affect to the performance of the individual. The main goal of this study is to provide an example of the application of the constraints-led approach in order to modify technical patterns of four technical gestures in Rhythmic Gymnastics. An example of the application in Rhythmic Gymnastics is presented. Some different kinds of errors to be modified because different reasons are shown. The proposal consists of some exercises designed in order to fix that mistakes. It can be seen that the same exercise may involve different practice loads depending on the features and the modulation of the task constraints, such as the material or the movement restrictions. Adaptation of the practice load is a main factor in the design of tasks when considering the characteristics of the learner, its sports level and the learning goals. We can apply this kind of work to other sports, but it is necessary to conduct practical investigations in this area to reduce the gap between the theoretical knowledge and its practical application.
Abstract
This paper examines the development of concepts related to education for sustainable development, such as sustainability education, sustainability and education, sustainable education, ...sustainable development education, sustainable didactics, and sustainable learning. The paper argues that these concepts are insufficient for designing educational processes that fully consider the factors of sustainable development. The paper proposes and justifies the need for new concepts: sustainable pedagogy, sustainable educational process, and didactics for a sustainable educational process. These concepts are based on the components of sustainable development: competence, health, and motivation and socialization. The paper discusses how to use these factors to assess the sustainability of educational approaches. It also provides a practical example of how to apply the “sustainability” methodology in the educational process using Google Lens in biology lessons.
All teachers--including career and technical education (CTE) teachers--play a vital role in building a thriving PLC Professional Learning Community. In this practical resource, the authors explicitly ...outline how to improve teaching and learning by integrating PLC best practices into CTE programs. Teams of CTE educators will learn how to clarify their purpose, discover their common denominators, and incorporate powerful collaborative processes into their daily work. This book allows the reader to: (1) Become familiar with the common issues that prevent CTE educators from engaging in the collaborative PLC process; (2) Learn why and how the PLC process benefits both CTE educators and students; (3) Learn how CTE educators can create collaborative programs that are tailored toward CTE fields of study; (4) Receive professional guidance and concrete, achievable teaching strategies for creating an effective PLC process; and (5) Access a checklist of crucial action steps for career tech teams at the end of each chapter. Foreword by Robert Eaker.
The era in which we currently live is .extremely extremely dominated by scientific and technological advances and technology, and has undergone significant changes over the past 230 years. The modern ...era is one in which technological innovations and scientific discoveries have had a huge impact on people's daily lives . The beginnings of attempts to conduct technical education in Poland date back to the 18th century , and over the following centuries the approach to this area hass evolved and changed . The adaptation of society to technological and scientific progress is crucial for the effective use of its benefits and to understand the changes that these innovations bring with them . Technical education aims not only to provide people with practical practical skills related to new technologies , but also to develop skills incl analytical thinking , problem-solving and adaptation to constant change . Nowadays , etc is crucially not only to learn how to use technology, but also to develop critical thinking skills to be able to evaluate and use these technologies responsibly .Today's technical education focuses on many areas , such as programming , engineering, science, computer science and digital technology.
