Published: June 2021

Abstract
There was proposed a method for studying and mapping the cognitive activity of the brain. The experiment simulates a flight situation: the appearance of an image, recognition, a motor act (inner speech). Electroencephalogram was recorded with cognitive load. Two figures are presented on the laptop screen- a circle and a square. At the moment of presentation of the stimulus, the matching device sends a synchronizing pulse to one of the inputs of the electroencephalogram amplifier. The subject mentally names a figure with a larger area. A selective filter system suppresses background activity. The resonant frequencies of the filters are changed to reveal a single cognitive response to a stimulus. The parameters of the model are individual for each subject. There was developed a model of a diagnostic device. The results obtained for the “circle” and “square” figures coincide at time interval corresponding to the work of the sensory visual system, but they differ at the stage of internal speech, which corresponds to pronouncing a longer word by the syllables. These results demonstrate the effectiveness of modeling in studies on the localization of the cognitive process and the diagnosis of neurological disorders.
Study of the effect of the elastic modulus of ribs on the stress-strain state of a composite mesh compartment
Authors: Repinsky V V , Bakulin V N 
Published: June 2021

Abstract
Modern fiber composites have extremely high specific strength and stiffness, significantly exceeding the corresponding characteristics of traditional metal structural materials. In the present work, the effect of the elastic modulus of circular and spiral ribs on the stress-strain state of a composite mesh compartment with cutouts reinforced with bezels investigated. For the calculations, the finite element method is used, which makes it possible to naturally consider the cutouts, stepwise varying thicknesses, various kinds of boundary conditions, and loads. The computational model of the composite lattice structure consisting of ribs is a finite element model constructed from beam elements. The parameters of the stress-strain state of a composite mesh compartment with notches reinforced by edgings are determined. The graphical dependences of the values of maximum stresses in the ribs and sheathing on the value of the modulus of elasticity are presented for the first time. The analysis of the obtained results carried out, which makes it possible to develop recommendations for an informed choice of carbon fabric types with different physical and mechanical characteristics for manufacturing the spiral and ring ribs, as well as the skin of the designed composite mesh compartments.
A fine-grained teaching activity to establish conceptual coherence in introductory physics concepts and representations
Authors: Ferreira A , Lemmer M 
Published: June 2021

Abstract
The sequence of representations used to introduce new knowledge and the context in which this is done is critical to both effectively build on prior knowledge and establish conceptual coherence in physics. Ongoing reports indicate that current teaching activities fail address student difficulties to obtain conceptual understanding and-coherence between relevant physics representations and concepts. There is a need for fine-grained topic specific multiple representational teaching activities to enhance coherence in physics knowledge. In this paper we present a teaching activity for undergraduate physics, built on using motion diagrams to specifically relate the concepts and representations in kinematics, in particular for the concept of free fall. The teaching activity follows a conceptual qualitative approach to teaching kinematics concepts and is informed by the results of a broader Design Based Research study. In the teaching activity the concept of acceleration is introduced qualitatively as the net force to mass ratio followed by drawing motion diagrams to visualize the motion of the objects in free fall. The motion diagrams are implemented to support conceptual qualitative interpretation of mathematical representations such as graphs and equations, to enhance transfer of knowledge between representations and coherence between relevant concepts and representations. The contribution of this research lies in presenting an argument for a conceptual qualitative approach to teaching introductory mechanics and introducing a teaching activity based on the value offered of including motion diagrams in the teaching activity to enhance coherence between physics representations and between physics concepts.
Misconceptions in mechanics and their elimination
Authors: Kuczmann Imre 
Published: June 2021

Abstract
Misconceptions are beliefs that contradict accepted scientific knowledge but they are seemingly supported by common-sense arguments. By testing misconceptions, we have deduced that they are also related to the structure of knowledge. Some basic elements of the incomplete knowledge structure have been identified, which promote the root of misconceptions to be persistent. Based on recognizing and eliminating these shortcomings, distinct guidance for the prevention or overcoming of misconceptions is proposed.

Published: June 2021

Abstract
It has now been established that the modern educational process is becoming more effective when using interactive, multimedia-rich educational resources that provide active teaching methods. The best way to meet these requirements are educational resources and virtual reality systems. An example of such electronic resources is virtual laboratory work, which can simulate the behavior of real-world objects in a computer-based educational environment and help students learn new knowledge and skills. This is relevant and already mandatory in the study of scientific and natural disciplines, such as chemistry, physics, mathematics, computer science and their combinations. Virtual laboratories contribute to increasing visibility, interactivity, as well as the formation of students’ cognitive and creative activity. In this regard, the development of a virtual model of a physical experiment on laboratory equipment that has a real analogue was the goal of this work. The paper presents data on the creation of the experimental setup interface developed in the laboratory of a pulsed plasma accelerator of Al-Farabi Kazakh National University, called the vacuum-arc accelerator (hereinafter VAA-1). At this installation, experiments are carried out to obtain coatings from various materials on a metal base from structural materials in order to create a protective and multifunctional layer on its surface.
Examining Students’ Interest in Physics at Second Level in Ireland
Authors: O’Neill D , Mcloughlin E 
Published: June 2021

AbstractThis study examines students’ interest in physics within the culture and context of the Irish education system, at both lower and upper second level. In Ireland, the majority of students (aged 12-15 years) complete an integrated science curriculum at lower second level that encompasses learning outcomes across the disciplines of physics, chemistry, biology and earth and space. Students can choose what subjects they continue with at senior cycle and typically, 13-14% of students (aged 15-18 years) continue to study physics. This study reports on the student’s interest in physics and presents collated responses from 563 lower second level science students and 142 upper second level physics students. The findings of this study denote the differences between males and females interests in studying Physics at each level and in particular, highlight the effect that school type has on females’ interest in physics.
Learning motion concepts using Augmented Reality Active Learning (AnReAL) activities
Authors: Rosi T , Onorato P , Oss S 
Published: June 2021

Abstract
Active learning and discovery-based laboratory curricula for the understanding of kinematics using motion sensors have extensively been studied in Physics Education Research for more than thirty years and provided strong evidence of their usefulness in terms of students learning and retention. More recently, activities based on video analysis software have also been developed and have become an important part of Physics Education Research. In this work we present a setup based on Virtual Reality (VR) headsets that may be used both for activities that are currently based on motion sensors and also for motion tracking. Our setup is based also on cameras that can be attached to the headsets in order to achieve an Augmented Reality experience. While VR headsets are mainly sold as gaming devices, they can be very interesting for Physics Education active learning activities: we called such an activity an Augmented Reality Active Learning (AnReAL) activity. As it will be shown, many curricula based on motion sensors or on video tracking can almost automatically be translated into AnReAL ones, while also being open for many new opportunities. In fact, following the emerging theory of Embodied Cognition, Virtual and Augmented Reality setups such as the presented one could prove to be very beneficial for information retention.

Educational reconstructions of quantum physics using the sum over paths approach with energy dependent propagators
Authors: Malgieri Massimiliano , Onorato Pasquale 
Published: June 2021

Abstract
Moving from the research tradition on the use of Feynman’s sum over paths approach in education, we have developed an educational reconstruction of elementary quantum physics which uses Feynman paths at fixed energy and is capable of a simple conceptual explanation of discrete energy levels in bound systems. The reconstruction has been found to offer several educational advantages, may help students think of quantum physics in a way more akin to how the subject is used by scientists, and allows to shed light on the relationship between energy and time.
Examining Irish Leaving Certificate physics examination questions (1966-2016) according to Bloom’s Revised Taxonomy
Authors: Letmon Damienne , Finlayson Odilla E , Mcloughlin Eilish 
Published: June 2021

Abstract
Over the past half-century free secondary level education has been introduced in the Irish education system and as a result a steady increase in the number of students completing a third level education has been observed. In tandem with this widening participation in second level education, curricula have been adapted to accommodate the varying needs and abilities of students while at the same time, addressing the changing role of science education in the national economy. Between 1966 and 2016, three different physics syllabi have been implemented at the upper secondary level in Irish schools. The focus of this study was to examine what were the cognitive demand of the Leaving Certificate Physics examination questions from 1966-2016. Bloom’s Taxonomy of Educational Objectives was used as a classification tool of the level of cognitive demand in the analysis of the examination question parts, as it has been used by the Irish Department of Education in the preparing the examination questions. A sample of nine Leaving Certificate Physics examination papers were selected as representative samples of the three syllabi spanning the fifty years. Despite clear changes in the three physics syllabi over the fifty year period with changes in examination question style, there was not a notable change in cognitive domains of examinations papers. All question parts were classified according to four levels of cognitive demand with the cognitive domain ‘remember’ coded most frequently (ranging from 73% in 1967 to 46% in the 2008 examination). Notably, none of the nine examination papers examined in this study contained questions (or question-parts) which coded for the cognitive domains of ‘evaluate’ or ‘create’.
Simple and Beautiful Experiments XII by LADYCATS and the Science Teachers Group: In memory of Hiroshi Kawakatsu
Authors: Ishii Kyoko , Tanemura Masako , Okiharu Fumiko , Onishi Haruka , Takahashi Naoshi 
Published: June 2021

Abstract
The LADYCATS (LADY Creators of Activities for Teaching Science) were founded in 2005 in cooperation with Professor Hiroshi Kawakatsu (1945–2018) to encourage both female physics teachers and students who want to study physics more, and primary school teachers who feel unprepared to teach physics-based lessons. We have demonstrated ‘simple and beautiful experiments’ together for the past 14 years. Our concepts are as follows: the ‘simple’ experiments are easy to complete, while the ‘beautiful’ ones are interesting, and the ‘essential’ experiments demonstrate the principles of physics. We lost our leader, Professor Hiroshi Kawakatsu, in 2018. He always said, ‘Everyone has a right to learn’. We follow in Professor Kawakatsu’s footsteps and demonstrate several educational experiments that he liked and demonstrated.

Published: June 2021

Abstract
Primary education is the first stage of compulsory education and aims to create equal opportunities for all children to achieve a balanced cognitive, emotional and psychomotor development tailored to individual needs. The paper presents informal activities implemented for elementary school students to familiarize them with simple sensors, actuators and BIT microcontrollers that can be programmed with simple software. The activities were carried out in four working groups, organized in the classrooms, the participants being pupils in the third grade. Activities began with a description of the term “robotics” and a short film showing the importance of educational robots. After the introduction into the world of robotics, high school students, member of Nano Tech Robotics Club, implemented interactive activities for elementary school students using Micro: Bit microcontroller and simple sensors.
Replat-Chaos-edu: an interactive educational tool for secondary school students for the illustration of the spreading of volcanic ash clouds
Authors: Haszpra T , Kiss M , Izsa É 
Published: June 2021

Abstract
The continental- and global-scale spreading of pollutants emitted from volcano eruptions or industrial accidents is an everyday issue in our life. Nevertheless, students are generally not aware of the fact that pollutant clouds do not spread in the atmosphere like dye blobs on clothes, rather an initially small and compact pollutant cloud becomes soon strongly stretched, while becoming filamentary and folded. This paper introduces an application called Replat-Chaos-edu by means of which students can investigate the characteristics of the atmospheric dispersion of volcanic ash clouds and other pollutants in an interactive way. The simulations utilize meteorological data and follow the time evolution of pollutant clouds consisting of a large number of individual particles. Replat-Chaos-edu is also a suitable tool for studying the so-called chaotic features of the advection. The software was tested at the Berzsenyi Dániel Grammar School and the Szent István Grammar School (Budapest, Hungary) in the framework of Physics classes and during a project week, respectively.

Abstract
Standards documents envision that students in grades K-6 engage in developmentally appropriate yet substantive learning in physics and physical science. Students are expected to engage in the practices of the discipline, trying to develop – and experimentally defend – their own explanations of rich everyday phenomena. Teachers need special preparation to meet this challenge. Traditional preparation in lecture-based science university courses or courses that emphasize engaging demonstrations with little intellectual ballast are unlikely to yield the kind of rich experiential and rich discourse-based instructional environment for young pupils to thrive. In this GIREP Symposium, speakers introduced promising models for teacher preparation and enhancement and contribute to a discussion in search of a coherent research-based agenda for like-minded GIREP members.
Validation of a survey to measure pre-service teachers’ sense of agency
Authors: Hull Michael M , Vormayr Katharina , Uematsu Haruko 
Published: June 2021

AbstractDissemination of reformed curriculum requires teachers to feel that they have the freedom to implement the curriculum in the classroom. Even instructors who are trained in research-based instruction and are convinced of its value might fail to implement the curriculum in the classroom if, for example, they feel a lack of support from their school or colleagues. In this talk, we will report on the validation process of a survey designed to measure a “teacher’s or pre-service teacher’s perceived agency“, which we define as “a feeling of being in control over what is taught and of how it is taught.”
Modeling in Pre-service Secondary School Teacher Education: developing an School Scientific Model of Energy
Authors: Soto M , Couso D , Pintó R 
Published: June 2021

Abstract
In this document, we will present the results of an investigation carried out in initial teacher education for pre-service secondary school Physics and Mathematics teachers in Chile. A Teaching and Learning Sequence (TLS) was iteratively designed following a Design-based research approach and implemented to promote the construction of an adequate School Scientific Model (SSM) of energy. This SSM is based on the well-known work on energy related concepts in physics education, including the ideas of energy degradation, conservation and transference. The methodology followed in the TLS is based on modeling and model-based inquiry. Subsequently, we have analyzed pre-service teachers’ qualitative productions to identify which model of energy they master at both the beginning and the end of the program. This allowed us to get hints of a learning progression in this field.
A special method of teaching Physics: Outdoors radioactivity measurements
Authors: Garamhegyi G 
Published: June 2021

Abstract
We recognised that students can be motivated by those issues they are personally affected by. Such topic can be nuclear radiation that we live in. The realization led to the school project of radioactivity measurement. We joined the international Safecast projekt. Safecast is an outdoors radioactivity measurement project that represents a long-term and effective way of informal teaching of Physics outside classroom environment.. We noticed a unique contradiction between the demand of developed nuclear technologies and the societal attitude declining these. After the disaster of Fukushima, people’s nuclear sense of security has decreased in a global extent. This model is a successful initiative worldwide for the restoration of trust. Results of the measurement can be viewed by people all around the world on Google Maps and they are incredible impressive. The implemented project is a decent combination of formal and informal learning, based on the model of research-based teaching. After our 1-year observation, we were able to encourage 20% of inactive students to participate in Safecast project – using an informal teaching style. In groups of 20 and 25, the sense of nuclear safety of members increased 18% and 22%.

Observer based Anti-windup technique for Twin Rotor MIMO System
Authors: Srinivasan C R , Chandrasekar S , Sasnika R , Srividya R 
Published: June 2021

Abstract
Necessary control techniques must be used in control systems for their proper and smooth operation even in the case of uncertainties and disturbances like sensor-actuator failure. The TRMS workshop serves as a simplified model of a helicopter retaining most of the important dynamic characteristics and cross coupling. This project aims to solve the problem of synthesizing anti-windup control technique based on observer to avoid controller signal entering into saturation in TRMS. The effects of saturation is that systems experience Integrator wind-up. Once the input saturates, the integral of the error keeps increasing. Any further change in the input does not lead to any change of the output of the saturated component. The system behaves like an open-loop configuration, and no control is available. The project applies a Sliding mode control algorithm to the TRMS and uses an observer as an anti-windup technique so that the system doesn’t cease to work even in the case of sensor failure. Using this scheme, the entire system of TRMS along with sensor failure was tested by giving step inputs and the outputs, pitch and yaw were obtained. The results obtained indicated that even in the presence of uncertainties, the system was able to track the given step input without going unstable.

Abstract
Ayurveda industry is one of the golden industries in ancient India which over the period had declined is witnessing a new surge up; this paper describes an automated approach for developing automated paste preparation machines for the health sector and Ayurveda industry. Automated paste preparation machine models are prepared on the basis of requirements and then tested and finally go into the manufacturing stage. This paper basically describes the methodology of preparation of machine models. In these automated paste preparation machine models, we use cam follower mechanism for the timed opening of valves to ensure the correct amount of ingredients to be instilled into the bowl. Control of opening and closing of valves through cam follower mechanism is achieved by the programming of gear motor with the help of Arduino Uno. An experimental case study is presented to show advantages, which include a verified reduction in model development time and improved modeling consistency and quality.
