Authors: Hanif Q , Budiyanto C W , Yuana R A 
Published: March 2021

Abstract
Computational Thinking is a skill that must be possessed in STEM learning. The abstraction process is at the core of CT. Abstract thinking is built on ideas and ideas based on experience. From the literature studies that have been read, many have adopted robotics media in education but researchers have not found the use of robotics media in the field of biology at the high school education level. Therefore, a systematic literature review was conducted to find out the latest developments regarding the topics in this literature. Therefore, this study highlights 3 points of the application of robotics in high school education to hone students’ abstract thinking skills. First, STEM can facilitate abstract thinking. Second, the role of robotics in education which is proven to increase student motivation. The third is the implementation of STEM learning in high school education. The search was limited to literature data-based publication outlets such as DOAJ, ERIC, Science Direct, and Google Scholar to maintain credibility. While previous research shows that students’ abstract thinking skills tend to be lower when using conventional learning. So that we need an approach such as STEM which is useful for solving a problem by utilizing symbols and is more effective in exploring concepts.

Published: March 2021

Abstract
This study explores the workplace competencies, especially in the production machine operators, and finds the existing gap between the competency of mechanical engineering graduates of Vocational High School (Indonesian: Sekolah Menengah Kejuruan; abbreviated as VHS) and the demanded skills in the workplace. The research method employed in this research is the qualitative-explorative research method. In this research, it can be acknowledged that in a broader aspect, the competencies of the mechanical profession of motorcycles, cars, and operators of production machines can be clustered into three groups of skills: base, core, and supporting competencies. Based on the four competencies’ competency map, the vocational school graduates’ basic competencies are unfulfilled in the production workshop: (1) reading the technical drawing and (2) using the hand tools. Moreover, VHS graduates of the mechanical engineering department are still shortage of core competencies, hence still occupying at “lack of comprehension” level equal to more than 33%. On the other hand, the vocational school graduates’ supporting competency is in a minor percentage, according to the workshop’s head, chief engine operator, and senior operator in the workshop.

Published: March 2021

AbstractInterpersonal intelligence is a person’s ability to communicate and interact with others consciously in different environments. The difference in the level of interpersonal intelligence affects communicating with other students. Mathematical communication skills are the ability to convey mathematical ideas either orally, in writing, or in motion. The purpose of this study was to see the mathematical communication skills of students with high interpersonal intelligence. The type of research used is descriptive qualitative with instruments in the form of tests of mathematical communication skills, interpersonal intelligence questionnaires, and interviews. The subjects of this study were 2 students from class VIII SMPN 2 Baki who have high interpersonal intelligence selected by purposive sampling. The triangulation used is method and source. The results of this study indicate that students with high interpersonal intelligence can meet all indicators of mathematical communication skills. However, some students have not fulfilled one of the indicators of mathematical communication skills, namely expressing real objects, situations, and everyday events into the form of mathematical models. One of the contributing factors is that students do not understand the information on the story questions presented, so students must be asked story questions related to everyday life.

Published: March 2021

Abstract
I have been working on an educational project called Comparative Geometry for decades. The project is based on teaching and learning plane geometry and spherical geometry simultaneously, mainly through direct experimentation with hands-on tools, and intensive use of discussion between classmates. This work has gravely been affected by the changes that occurred two months ago because of the pandemic, still causing emergencies in many areas of education. In this article, I describe how I tried to adapt the work of a university course to an emergency; the methods by which I enabled direct experimentation and personal communication that were not possible in the given situation; my efforts to reduce the drawbacks of the situation and take advantage of the potential benefits.
Learning by experimenting as a good way to effective and student friendly mathematics education – experiences from Young Explorer’s Club
Authors: Rybak A 
Published: March 2021

Abstract
Students in many countries have problems with learning of mathematics. Many students do not like mathematics. Teachers and parents are mostly aware that the style of teaching of mathematics and “the atmosphere” around mathematics are the main reasons for this state. For the society it is clear that something must be changed. Maybe methods of teaching, maybe the whole system? Copernicus Science Centre in Warsaw 18 years ago proposed the idea of Young Explorer's Club (YEC) as the environment where students can discover knowledge by making experiments. Learning by experimenting, by own activity of learners makes the whole educational process more interesting and less frustrating for students. This also applies to mathematics education. Experiences from mathematical Young Explorer's Clubs established at the Centre for Creative Mathematics Learning at the Faculty of Mathematics University of Bialystok as the possible way to more effective mathematics education will be presented in the paper. Experimenting and using functional strategy of teaching of mathematics is the basic form of activity in the Clubs.
Training pre-service mathematics teacher to use mnemonic techniques
Authors: Drushlyak M G , Semenikhina O V , Proshkin V V , Sapozhnykov S V 
Published: March 2021

AbstractThe article reveals the issue of the appropriateness of training pre-service mathematics teachers to use the techniques of mnemonics in professional activities. This issue is caused by the intensification of the educational process, when the amount of information accumulated by mankind is many times greater than the amount of knowledge that can be learned by a particular person. It is established that in the process of teaching mathematics, mnemonics should be used as a way of perceiving new information due to the formation of associative connections using special methods and techniques. The expediency of training pre-service mathematics teachers to use various methods of mnemonics (“Binding”, “Transformation”, “Amplification”) is substantiated. A positive attitude of mathematics teachers towards the use of mnemonics techniques was revealed, as well as a low level of students' understanding of the advisability of using mnemonics techniques in professional activities. The classification of software used to create visual models is presented. A training was developed and introduced into the practice of university education on the development of mnemonic techniques for the presentation of educational mathematical material. The prospects of scientific research through the development of methodological support for the training of pre-service mathematics teachers to use the techniques of mnemonics in professional activities are determined.

Abstract
The importance of our research is due to the need to introduce into modern biological education methods of predictive modeling which are based on relevant factual material. Such an actual material may be the entry of natural and anthropic heavy metals into the soil at industrial areas. The object of this work: (i) to work out a predictive model of the total heavy metals inputs to soil at the Kryvyi Rih ore-mining & metallurgical District and (ii) to identify ways to use this model in biological education. Our study areas are located in the Kryvyi Rih District (Dnipropetrovsk region, Central Ukraine). In this work, classical scientific methods (such as analysis and synthesis, induction and deduction, analogy and formalization, abstraction and concretization, classification and modelling) were used. By summary the own research results and available scientific publications, the heavy metals total inputs to soils at Kryvyi Rih District was predicted. It is suggested that the current heavy metals content in soils of this region due to 1) natural and 2) anthropogenic flows, which are segmented into global and local levels. Predictive calculations show that heavy metals inputs to the soil of this region have the following values (mg ⋅ m2/year): Fe – 800-80 000, Mn – 125-520, Zn – 75-360, Ni – 20-30, Cu – 15-50, Pb – 7.5-120, Cd – 0.30-0.70. It is established that anthropogenic flows predominate in Fe and Pb inputs (60-99 %), natural flows predominate in Ni and Cd inputs (55-95 %). While, for Mn, Zn, and Cu inputs the alternate dominance of natural and anthropogenic flows are characterized. It is shown that the predictive model development for heavy metals inputs to soils of the industrial region can be used for efficient biological education (for example in bachelors of biologists training, discipline “Computer modelling in biology”).

Published: March 2021

Abstract
Machine learning is now widely used almost everywhere, primarily for forecasting. In the broadest sense, the machine learning objective may be summarized as an approximation problem, and the issues solved by various training methods can be reduced to finding the optimal value of an unknown function or restoring a function. At the moment, we have only experimental samples of quantum computers based on classical-quantum logic, when quantum gates are used instead of ordinary logic gates, and probabilistic quantum bits are used instead of deterministic bits. Namely, the probabilistic nature problems that provide for the determination of a certain optimal state from a large set of possible ones on which quantum computers can achieve “quantum supremacy” – an extraordinary (by many orders of magnitude) reduction in the time required to solve the task. The main idea of the work is to identify the possibility of achieving, if not quantum supremacy, then at least a quantum advantage when solving machine learning problems on a quantum computer.

Published: March 2021

Abstract
The article deals with the concept of student-centred Personal Learning Environment (PLE) in the context of higher education, which is used as a means of transforming foreign language learning and teaching practices. It aims to reveal the opportunities for creating PLEs through incorporating Information and Communication Technology (ICT) in the process of foreign language education. The study focuses on the roles of teachers and students of non-language University majors in designing efficient learning environments highly adapted to changing objectives and student personal needs. The authors reveal the unlimited potential of ICT in constructing PLEs for both in-class activities and informal learning, providing a scope of practical student activities, which imply their active engagement both in and outside the classroom, as well as constructing a flexible, personalized, time and space independent learning environment. Students, teachers, ICT, which is a set of resources based on the use of educational technology tools thoroughly selected and organised in order to manage the content, applying relevant methods of teaching and learning strategies, as well as a learning process, are all regarded as constituents of PLEs aimed at mastering four foreign language skills when taking the course “Foreign Language for Specific Purposes”: reading, listening, writing and speaking within personal, academic, and field-related contexts.
