Project VLAB-FIS: a novel approach to engage students on experimental work in Physics
Authors: Carvalho P Simeâo , Machado N A , Araujo P P 
Published: June 2021

Abstract
Experimental work is very useful for motivating high school students towards science, leverage learning and also for developing procedural skills. Teachers usually provide their students with protocols of the experiments and expect to obtain good results from this practice, but students must be prepared before going to the lab in order to successfully accomplish the experimental work. The project VLAB-FIS is based on introductory videos that give a holistic view of the experimental works, facilitating a prior understanding of the experiments and their corresponding conceptual goals. The approach is complemented by video recordings of the experiments and computational simulations, for an inclusive participation of all students regardless of reading or physical disabilities. The project was presented to physics teachers in a workshop to better understand the feasibility of the project in Portuguese secondary schools from the teachers’ viewpoint. Teachers’ feedback shows that they consider the project useful as support for the preparation of laboratory classes.
Field lines in art and physics
Authors: Stonawski’ Tamás , Fülöp Csilla 
Published: June 2021

Abstract
The physical space surrounding us is not empty, it is filled by objects and fields. Macroscopic objects are visible, but fields can only be detected with sensitive instruments rather than the naked eye. Physicists introduced visual clues (field lines, trajectories, streamlines, equipotential surfaces) based on helpful mathematical concepts to characterize (the mostly invisible) physical fields. These illustrations are used in high school-level physics, but – due to their abstract nature – are not easily understood by students. Most of the confusion is caused by students mistaking the plotted auxiliary concepts for physical reality. We can help their understanding by drawing parallels between the visual representation of fields and the technical methods used by a painter to express the subject.
Beauty and physics — Physics projects based on modern aesthetic and medical treatments
Authors: Nagy Anett 
Published: June 2021

AbstractAs a natural science, physics seeks to answer questions that arise in the world around us. One of the areas of motivation is to show students that a number of devices and treatments used in the beauty industry or for staying healthy apply the laws and phenomena of physics. Examining the physical background of various, modern treatments can be used to raise simple and complicated issues in physics and also provides us the opportunity to carry out qualitative or quantitative experiments. We believe that these projects assist students in a better understanding of physics and also encourage teachers to make the subject more interesting.

Published: June 2021

Abstract
Development of inquiry skills is still in the main focus of science educators in Slovakia. Large effort has been recently put into the implementation of inquiry-based science education. In this research, the current level of development of selected inquiry skills has been monitored and analysed. For this purpose, a multiple-choice test of selected inquiry skills was designed. The tested skills involve formulating hypothesis, designing experiment, transforming results into tables and graphs, determining relationships between variables based on tables and graphs and identifying possible sources of errors. The test was implemented across several thousands of upper secondary school students. The inquiry skills´ test results revealed significant lack of their development. The paper describes the test design as well as it analyses and interpret the test results.
Effect of motion simulation programs in teaching force concept1
Authors: Radnai T , Juhász T Tóthné , Juhász A , Jenei P 
Published: June 2021

Abstract
The most important concept in dynamics is force. Teaching forces in secondary schools has many difficulties, due to the fact that when students start learning dynamics, they have already developed a force concept based on their everyday experiences. This concept is usually simplified and often confused with impulse. However, the concept taught on physics lessons, is a much more complex, based on a vectorial quantity, with a time-dependent direction and magnitude. This confusion of concepts can be largely eliminated by the visualization of force vectors during the motion of an object. This opportunity is available in motion-simulation software, which work as a digital sandbox, allowing users to create their own scenes and display force vectors during the simulations. Connecting kinematics by motion visualization and dynamics by force visualization is a powerful tool that helps students to develop deeper understanding in mechanics. In our educational research, we investigated the positive effect of using such a program. With the participation of 700 students, divided into experimental and reference groups, we measured their development in understanding mechanics. The results proved that students who used the simulation program reach a better functional understanding of the concept of force than those being in the reference group.
How high schools teach quantum physics – a cross-national analysis of curricula in secondary education
Authors: Stadermann H K E , Berg E van den , Goedhart M J 
Published: June 2021

Abstract
Quantum physics (QP) changed our worldview, it brought us modern electronic devices, and its almost mythical image fascinates. Although QP is relatively new in secondary education, it is now part of the national curricula of many countries. To understand the current state of QP content in high schools, we scrutinised upper secondary school physics curriculum documents in 15 countries. In these countries, we identified a similar core curriculum of QP which contains the following seven main categories: discrete atomic energy levels, interactions between light and matter, wave-particle duality, de Broglie wavelength, technical applications, Heisenberg’s uncertainty principle, and the probabilistic nature of QP. We also found differences in the focus of the listed topics of individual countries, which indicate different views on teaching QP. The thematic focus of QP items is related to the underlying goal of science education and to the way students’ knowledge is tested. This overview shows which QP content is generally feasible at a secondary level and which pedagogical perspectives are possible. Therefore this study might lead to reflections on existing QP curricula, and inspire countries that do not have QP in their curriculum yet.

Physics and Mathematics university students’ ideas about computer simulations
Authors: Barelli Eleonora 
Published: June 2021

Abstract
In an increasingly complex world, the science of complex systems is well-positioned to provide epistemological lenses and methodological tools to analyse the reality. Among the tools developed, computer simulations have a crucial role, but the ways in which they are conceptualized by graduate and undergraduate students have not been extensively explored. Framed within a wider research about the educational role of simulations of complex systems, the goal of this work is to provide insights into the understanding about simulations of university Physics and Mathematics students. For this purpose, a study has been designed with a group of bachelor and master students within a course of Physics Teaching. The object of this paper is to present the results of the data analysis of the preliminary questionnaires, where 27 students were asked to express their ideas about simulations. The bottom-up process of qualitative analysis has allowed to point out, and organize in categories, different ways in which simulations are conceptualized by the students, in terms of: i) scope for which simulations are used, ii) their relationship with experiments and models, and iii) the examples of simulations they refer to.

Published: June 2021

Abstract
In this paper we are presenting the design and evaluation process of a Teaching Learning Sequence (TLS) following Design Based Research (DBR) methodology. The TLS was designed for the upper secondary school students on particle dynamics. In this work, we present the very first results of the process. The iterative DBR methodology is presented giving evidences about design decision and tools for evaluation. This TLS was implemented in a post compulsory high school in the Basque Country. The results obtained in the first implementation show that there are improvements in the learning achieved by students in comparison with a control group. The strengths and weaknesses of the TLS will be analyzed for future redesign phase into DBR phases.

Abstract
Classroom demonstrations and experiments have played an important role in physics teaching for centuries. They are important for deepening student knowledge and helping students gain meaningful understanding of physical principles. In addition, experiments can motivate stu-dents and facilitate their active engagement with abstract concepts. In this paper, we present four novel physics experiments and demonstrations that address the pedagogical needs of the 21st century physics teaching. These experiments: (a) employ modern technologies that bring physical phenomena closer to the students; (b) showcase teaching methods that reduce barriers for the students with special needs; and (c) suggest an innovative thermodynamics demonstration related to environmental issues and green energy. The descriptions of the experiments, their applications to secondary school teaching as well as to college-level physics education are thoroughly discussed.

The influence of high school teachers on the representations of the role of an “exemplary teacher” according to future physics teachers
Authors: Nardi Roberto , Reis Belíssimo Jéssica dos , Parma Fabiano Willian 
Published: June 2021

Abstract
We highlight here part of a longitudinal study, which sought to follow a group of future physics teachers and explain how research has been introduced in or affected their initial training. We seek to analyse their representations of the role of an ‘exemplary teacher’, considering that some of the graduates affirmed to have chosen a career as a teacher because of the influence of their high school teachers. The data were collected through questionnaires administered at the beginning of the study to students enrolled in the teacher education programme and treated by Discourse Analysis. We compare students’ representations with five dimensions that characterize an “exemplary teacher”. The results show that the characteristics of their high school teachers appear in the discourse of the students when they refer to an “exemplary teacher”.

Published: June 2021

Abstract
This work presents a series of lessons containing didactic experiments, as well as the related educational research. The series concerns the instruction of prospective primary school teachers who possess a weak Physics background. The main topics of instruction are: basic concepts of wave behavior (mainly interference and diffraction), as well as the wave properties of light. This instruction is based on POE (Predict-Observe-Explain) techniques. It constitutes the basis of a broader effort in the making, which aims at teaching future teachers about wave properties and wave-particle duality. The benefits of teaching such notions of waves to teachers are examined, the learners’ previous knowledge and their views are scrutinised, and their learning progress is monitored. As a further step, the overall outcome of the improvement of learners’ knowledge regarding the given concepts is examined, using educational research tools.

Comparison of a decade’s data between LST and NDVI data for agricultural drought analysis in Rayalaseema region, AP, India
Authors: Damarla Gayathry , Kavuri Naga Chaitanya 
Published: June 2021

Abstract
Drought is an extreme weather condition that disturbs agricultural production by raising the temperatures and altering precipitation patterns. As agriculture in India heavily depends on monsoon, any changes in these patterns will severely affects its agricultural economy. Rayalaseema is one of such regions which was hit by sever draught conditions in past few decades. The region depends on the traditional agricultural economy; thus, not only production but also the life of the common man is influenced by the impact of drought on agriculture. The purpose of this study is to investigate vegetation stress in the Rayalaseema region with the help of normalised difference vegetation index (NDVI) values and land surface temperature (LST) for the years 2011 and 2019. To measure both NDVI and LST, satellite data is used. A clear interdependency between LST and NDVI was observed and it was found to be a negative correlation between them. The correlation values for 2011 and 2019 between LST and NDVI were found to be -0.44577, -0.80447 respectively. The influence of rain fall data was also discussed in the study to explain the increase in NDVI values during the last quarter of 2019.

Published: June 2021

Abstract
The work focuses on the improvement of strength-weldability combination in Friction Stir Welding (FSW) joint of 7075 and 6061 Aluminium Alloys. Although Al-6061 and Al-7075 both are heat treatable but they are having somewhat different mechanical properties. The 7075-T6 has more tensile strength and hardness than that of 6061-T6.The lower hardness of 6061-T6 allow it to weld easily whereas 7075 prone to cracking during welding. Owing with the result that FSW could play significant role in order to improve the weldability, microstructure of cross section as well as the mechanical properties of joint was characterized. The welds were considered by using three rotational speed and three feed. It was revealed that the tensile strength of the joint (153.13 MPa) became very less in comparison to the base metal and it has been decreased again when the speed decreases from 700rpm and 15mm/sec to 2000rpm and 25mm/min.The findings such as tensile strength as well as the fracture revealed that mechanical properties and the microstructure of welding are not desirable for any structural application.

Abstract
The scope of our project is to notify the owner of the premises, the fire department and authority immediately after the detecting any fire and gas leakage by sensor. The notification is sent through Short Message Services (SMS). The issue we are trying to solve here is associated with the emergencies which can occur in any industry or large factories in this case fire. This can also help us to reduce the response time taken by the first responders. As soon as the sensors detect fire or smoke buzzer will go off and SMS will be sent to all the authorities. The path to the development of the automation system at home and in industry is almost the same these days. This paper will help us to understand the measures which we can take to create a fail safe system for fire or gas detection in large areas at low cost. Everyone wants to be safe as much as possible. The easy connection simple to understand will help every user to use the wireless system for security using the sensors-Gas, smoke, and temperature detector at industries.
