Methodological suggestions for creating subquestions for the Force Concept Inventory (and other research-based assessments)
Authors: Hull Michael M , Yasuda Jun-ichiro , Mae Naohiro 
Published: May 2024

Abstract
The Force Concept Inventory (FCI) is a research-based assessment that is used internationally to assess student understanding of Newtonian mechanics. The assessment has been investigated from a number of perspectives and many suggestions have been made for its improvement. One suggestion is the creation of subquestions. Subquestions are a tool to reduce false positives (answering a survey item correctly without correct understanding) and false negatives (answering incorrectly despite correct understanding). In this presentation, we will discuss how we created subquestions for two items on the FCI, informed by survey-based interviews with students and the original intended targets of the items. Our research aims are not only to present the subquestions we developed, but to share our methodology of creating these subquestions, as this methodology can be used in general for producing subquestions on other research-based assessments as well.
Multimodal expressions of disciplinary relevant aspects in inquiry-based physics learning
Authors: Andersson Roger , Jääskeläinen Markku 
Published: May 2024

Abstract
In this study we are interested in how learners of geometrical optics express disciplinary relevant aspects multimodally in an inquiry-based learning with support of a computer simulation. Students’ discussions and work with the simulation were filmed, transcribed, and we analysed some parts of the transcript where the students show signs of disciplinary relevant aspects by a method based in conversation analysis. We found evidence that the students use multiple semiotic resources for expressing disciplinary relevant aspects about the tasks, especially gestures. The letter are by their visual nature well suited for communication in physics, and are used by the students to transduct semiotic information.

Published: May 2024

Abstract
While lab courses are an integral part of studying physics aiming at a huge variety of learning objectives, research has shown that typical lab courses do not reach all the desired goals. While diverse approaches by lab instructors and researchers try to increase the effectiveness of lab courses, experimental tasks remain the core of any lab course. To keep an overview of these developments and to give instructors (and researchers) a guideline for their own professional efforts at hand, we introduce a research-informed framework for designing experimental tasks in contemporary physics lab courses. In addition, we demonstrate within the scope of the EU-co-funded DigiPhysLab project how the framework can be used to characterize existing or develop new high-quality experimental tasks for physics lab courses.
Exploring students’ views about basic concepts in introductory quantum mechanics
Authors: Giuliana G. , Marzoli I. , Testa I. , Scotti di Uccio U. 
Published: May 2024

Abstract
Literature in physics education shows that students still experience difficulties learning quantum mechanics, although it is now part of the high school curriculum and many research-based proposals are available. Prior works mostly focused on specific misconceptions and a clearer picture of students’ ideas on general quantum concepts is still lacking. We addressed these issues by inspecting, through multiple correspondence analysis and cluster analysis, the responses given by 408 Italian high school and undergraduate students to a Likert scale questionnaire on quantum physics. From our preliminary results, we can conclude that the majority of students leave high school and enter university without a sound model of the quantum world.

Authors: Lovisetti Luisa , Melli Ester , Giliberti Marco 
Published: May 2024

Abstract
This paper describes the work of design, testing and evaluation of the effectiveness of a pilot teaching-learning sequence on Quantum Mechanics (QM) presented to high school students and teachers. The aim is to construct a path starting from the discussion of real experiments to get to the mathematical basic structure of QM, and to test whether this path can be effectively proposed at high school level. The experimentation consisted of 10 Zoom meetings, between October 2021 and January 2022. At the end of each of the first nine meetings, each student was given a form aimed at bringing out the reasoning used, and the level of understanding achieved. At the end of the course a satisfaction survey was also given. The effectiveness of the activity was assessed by means of all homework and interviews with 13 students and 6 teachers.

Authors: Satanassi Sara , Ercolessi Elisa , Levrini Olivia 
Published: May 2024

Abstract
The teaching of quantum technologies has now become a leading topic and is at the heart of numerous international programs (e.g., quantum flagship, National Quantum Initiative, UK national quantum technology program) with the aim of widening the workforce and preparing the next generations of experts. In the present contribution, we present an approach for teaching the Second Quantum Revolution to secondary school students that we developed in recent years. The approach aims to emphasize the ongoing revolution as first of all a cultural revolution and its intrinsic interdisciplinary character. As an emblematic case of some aspects of the approach, we present an activity on the classical and quantum random walk algorithms whose main aims are to recontextualize some basic quantum concepts (quantum state, state manipulation/evolution, measurement, and entanglement) in the case of the algorithm and to reflect on the main differences between the classical and quantum case in terms of logic behind its functioning as well as from an epistemological perspective.

Published: May 2024

Abstract
The paper presents the results of the study in physics learning during the pandemic in Croatian schools. The aim of the study was to identify students’ views on physics lessons and problems with the online study process, as well as their knowledge. Data were collected by an online questionnaire in the school year 2020/2021 and knowledge tests for each level of pre-university education for two testing cycles, school year 2020/2021 and 2021/2022. The results of the questionnaire show that, from the students’ point of view, teaching during the pandemic was as detailed as in regular classes, and experiments were conducted very rarely. The knowledge test results show the difference in the level of physics knowledge in the pre-pandemic period, during online and hybrid classes.

Evaluation of a university seminar on the use of digital media in the physics classroom
Authors: Weiler David , Burde Jan-Philipp , Große-Heilmann Rike , Lachner Andreas , Riese Josef , Schubatzky Thomas 
Published: May 2024

Abstract
Fostering digital competencies is an important aspect of pre-service teacher education. However, for physics, there is a lack of systematically surveyed and evidence-based seminars that specifically take into account relevant research findings. Thus, we developed a research-based seminar on the effective use of digital media in physics classrooms and investigated its effects on pre-service teachers (PSTs) professional competencies in a mixed-methods design. Our quantitative analyses of different competence components surveyed in a pre-post-design indicate that the seminar leads to an increase in motivation to use digital media in the physics classroom. Nevertheless, no significant increase in digital-media PCK was found, which could be due to the small sample. The seminar design, however, was predominantly evaluated positively by experts and PSTs in guided interviews. Based on the results, it is planned to further refine the original seminar using a Design-Based Research approach.

Published: May 2024

Abstract
Sensors for use in schools within physics education have a firm place in many educational systems. However, even in these educational systems, some teachers do not use them. In this contribution, we offer preliminary ideas leading to the preparation of a typology of physics teachers. We start with the model of personality developed by C.R. Cloninger and proceed with preliminary work by the team from the University of Wisconsin-Madison, focused on Teachers on the Market: A Typology of Teachers’ Philosophy, Mission, Vision, and Values. Finally, we try to ground our work on the neuroscience view of teachers formulated by T. Tokuhama-Espinosa.

Published: May 2024

Abstract
This study looked into the possibility of substituting marble dust for some of the fine aggregates used in concrete production. The purpose was to determine if such a substitute may improve concrete’s properties while also minimizing the negative consequences of mining and processing natural sand and assisting in the attainment of sustainability goals. Experimental testing was done on a variety of concrete mixtures that contained various amounts of sand and marble dust. Compressive strength, flexural strength, and workability were evaluated for a control mix consisting entirely of unrefined sand. The results showed that there was little difference in concrete’s compressive or flexural strength when up to 30% marble dust was used in place of sand. The workability and strength, on the other hand, decreased as marble dust concentrations rose. contains marble dust.

Abstract
“The population of India is the second highest in the world as per the 2022 report” [1]. In order to live well, there is an increasing demand for adequate infrastructure. People are migrating from rural to urban regions. Problems will rise due to the high population in urban areas. Due to a lack of available land for construction in metropolitan areas, high-rise building structures are becoming more necessary to address the population density issue. High-rise structures are in high demand, and their construction must be completed without compromising any of the three criteria of cost, timeliness, and safety. AutoCAD design software enables the production of both 2D and 3D drawings for use in constructing multi-story buildings. This study aims to utilize the software package STAAD-Pro to analyze and design a multi-story building, following the production of 2D and 3D drawings using AutoCAD. STAAD-Pro offers a far quicker method of structural analysis and planning for the likelihood of the fewest faults. The design involves load calculations and analyzing the whole structure by STAAD Pro. “The method used in STAAD Pro analysis is Limit State Design followed by Indian Standard Codes. The loads considered for designing the building are dead loads, live loads, and Wind loads. For analyzing a multi-storied building, one has to consider all the possible loadings and see that the structure is safe against all possible loading conditions” [2]. The aim of this study is to analyze the structural behavior of the building and ensure that it meets the necessary design standards and codes. To remain competitive in the constantly expanding market, it is crucial for structural engineers to optimize their time management. This study highlights the importance of using advanced software tools in the design and analysis of complex structures to ensure their safety and stability.

Modelling and numerical simulation of high-speed railway slab track structure
Authors: Chholak Kiran , Dev Nirendra 
Published: May 2024

Abstract
In terms of maintenance and structural behavior, slab track proves to be an advantage over conventional ballasted track due to increasing train speed, axle load, and traffic density. Since the vibration, noise, and risk of derailment, all accelerate as train speed increases, an in-depth investigation of track dynamics becomes essential for identifying the fundamental cause of the problem. In this paper modelling and numerical simulation of high-speed railway slab track structure has been studied using finite element method. Using the multi-body simulation approach and the finite element method a model of the 3D slab track system is developed. The slab track model has rail, rail pad, and concrete slab, HBL, and subgrade layers. In order to determine the fundamental frequency and the mode shapes associated with it, a modal analysis is carried out. Dynamic response, or acceleration against frequency curves derived via harmonic response analysis, is the result of the numerical simulation. The dynamic reaction of the structure of a high-speed slab track is studied, and the effect of elastic materials on reducing vibration is investigated. The results suggest that a layer of elastic material, like a slab of mat, inserted between a layer of concrete slab and a layer of HBL is capable of lowering the amount of vibration response of the track.

Authors: Mehra Nishant , Swain Janaki Ballav 
Published: May 2024

Abstract
The small cities in the Asian subcontinent are supposedly going to witness exponential growth in the next two decades. The situation could be very challenging in Himalayan cities owing to topo-geographical complexities and limited resources in the region. The increasing population coupled with being a favored tourist destination had resulted in dispersed, inefficient, and unplanned built-up activities in the region. Monitoring the urban sprawl can help in adopting sustainable development strategies equally balanced towards the society and environment. The availability of geospatial data integrated into the GIS interface can help immensely in monitoring and measuring LULC changes and thereby help in formulating necessary interventions and strategies for realizing a sustainable ecosystem. The present study employs Landsat imagery for creating the built-up land cover maps for the year 2016, 2019, and 2022 and the ALOS-PALSAR Digital Elevation Model for understanding the trend and direction of urban sprawl in Dharamshala city. It was found in the study that the built-up dynamic index had increased to 23.3% from the year 2016 to 2022. The built-up growth rate for the study period was found to be 145% for the elevation less than and equal to 1000m, 143% for elevations ranging from 1000-1500m, and 119% for the elevation greater than 1500m. The built-up growth rate for a distance up to 100 m from the streams was 119% from the year 2016 to 2022. The geospatial risk assessment highlights potential threats in the region due to increased built up activities, emphasizing the need for prompt intervention by policy-makers, administrators, and environmentalists to advocate for a sustainable development model.
Impact of Humic Acid and Sulphur application on growth and yield of Indian Mustard under variable Water moisture regimes
Authors: Manna Toko , Siddique Anaytullah 
Published: May 2024

Abstract
Indian mustard (Brassica juncea L.) is an important oilseed crop cultivated in various regions of the world, particularly in India. However, its productivity faces limitations due to various abiotic factors, notably variable soil moisture. This study aimed to explore the influence of humic acid and sulphur application on Indian mustard growth and yield within different moisture regimes. A field experiment was conducted in rabi season, employing a split plot design with four replications. Four moisture treatments were imposed: (1) no post sowing irrigation, (2) one post sowing irrigation (3) two post sowing irrigation and (4) three post sowing irrigation. Within each moisture regime, four treatment groups were established: (A) control (no application), (B) humic acid alone, (C) sulphur alone, and (D) a combination of humic acid and sulphur. The results revealed significant improvements in various growth and yield parameters when humic acid and sulphur were applied, particularly under moisture stress conditions. Application of humic acid and sulphur enhanced root development, chlorophyll content, and photosynthetic rate, which ultimately led to increased plant height, leaf area, and biomass accumulation. Notably, the combined application exhibited synergistic effects, resulting in the highest yield increments, especially under severe moisture stress. This study provides valuable insights into the potential advantages of incorporating humic acid and sulphur as soil amendments in Indian mustard cultivation, particularly in moisture-variable regions. The results highlight the combined application’s effectiveness in mitigating water scarcity effects, thereby promoting sustainable agriculture and bolstering food security.

Authors: Shende Ashay Devidas , Sahoo Mrunmayee M. , Tekade Shrikant A. 
Published: May 2024

Abstract
With the help of multiple indices (SAR, LI, RI, SSP, and RSC) for irrigation, the current study set out to determine the level of groundwater pollution in the Wardha region. The research involved 15 villages in the Wardha District, five from each of Wardha, Seloo, and Hinganghat. Over the course of two years, 90 samples were taken from fifteen groundwater structures. 13 physicochemical factors and 5 indices were evaluated using analysis. The study discovered that the groundwater sources in each of the 15 villages in the Wardha District are contaminated, making the water unfit for human consumption and necessitating some sort of filtration before usage for domestic or agricultural purposes. The findings of Langlier that practically all groundwater samples exhibit factors that cause scaling are supported by the Ryznar index values, which range from 5 to 7. SAR data indicates that around 60% of the groundwater being examined had low levels (10.0).

Abstract
Water is unpolluted for life, but when it is polluted, it dies. we are known pollution big problem for any country today. An engineer is a scientist who finds a solution to this problem. Some major problems for Environment pollution are water, air, land and sound pollution. This pollution is harmful to the environment, humans, wildlife, and ecosystems. It also affects aquatic life and water parameters. Not only India but also other countries suffer from the same problem. Air pollutants increase the alkalinity of the water surface with the changes of Ph, BOD and turbidity, which directly affects the water surface. Some human activities that affect water quality include fertilizers, mining, industrial waste emissions, animal activity, domestic waste, burning fossil fuels, especially coal, and as-loaded water for irrigation. Water use, As-based pesticides, herbicides, and leisure activities. Air pollution and smoke debris are a complicated combination of natural and inorganic debris which include soot, smoke droplets and aerosols. The purpose of this study is to produce pm diagrams of water quality parameters such as turbidity, COD, pH, Total dissolved solids, and hardness.
