Published: October 2024

This special issue, which continues the series from the International Conference on Physics Education 2022, focuses on the theme "Physics Education: Preparing for the Future." The contributions underscore the pressing need to adapt and evolve educational practices to meet the challenges and opportunities facing tomorrow’s learners.
A central theme of this collection is the integration of innovative methodologies and technological advancements into physics education. Collectively, these papers emphasize the importance of evolving teaching practices to better equip students and educators for the demands of modern physics education. Nguyen, Nguyen, and Tran demonstrate the effectiveness of inquiry-based laboratories in enhancing the experimental skills of pre-service teachers, underscoring the value of hands-on, active learning in developing critical competencies. In parallel, López-Garduza, Ramírez Díaz, and Cabral-Rosetti explore misconceptions in electrostatics among educators, revealing the ongoing need for professional development to ensure that teachers can accurately and confidently teach complex concepts. These findings are echoed in Puttisanwimon and Wuttiprom's study, which examines student misconceptions in mechanical waves, suggesting that more interactive and conceptually focused teaching strategies are essential to overcome deeply rooted misconceptions.
Further advancing the discussion, Castiblanco Abril and González Aldana advocate for a shift in teacher training towards the mathematization of physics, proposing a more holistic, concept-driven approach that moves beyond traditional equation-based methods. This theme of innovation extends to the work of Kiss, who explores how the COVID-19 pandemic has transformed the use of teaching resources, with digital tools and online platforms now playing an integral role in both distance and in-person education. Finally, Santana Fajardo, Rodríguez Pérez, and Vázquez Mercado provide an in-depth look at the design process for a new Master of Science in Physics Education program at the University of Guadalajara, aiming to prepare educators with the research skills and competencies needed to address the evolving demands of physics education.
Together, these papers offer a comprehensive analysis of the current state of physics education and propose strategies to address its challenges. They underscore the need for continuous innovation, the importance of addressing misconceptions at both student and teacher levels, and the critical role of technology in modernizing educational practices.
I extend my gratitude to all the authors, reviewers, and conference organizers for their contributions to this special issue. It is my hope that this collection of articles will inspire further research and discussion on the future of physics education.
The Diary of the Sky as a methodological strategy to teach Astronomy in Elementary School
Authors: Dias Fernandes Telma Cristina , Nardi Roberto , Lanciano Nicoletta
Published: October 2024

The aim of this paper is to describe some activities undertaken at different phases of a broader research project named “The Northern and Southern Skies: Teaching astronomy in schools”. This project is a collaborative agreement between São Paulo State University (Bauru Campus, São Paulo, Brazil) and La Sapienza Università (Rome, Italy). The project aimed to bridge the gap between the academic production in the field of astronomy education and the classroom experiences of elementary school teachers and their students. The project finds justification in the fact that elementary school teachers, in general, face significant challenges when teaching astronomy elements to their students. In this article, we describe some steps of this project and the teaching resource named Diary of the Sky and its implementation, starting with the translation of the original Il Diario del Cielo, in its Italian version, to Brazilian Portuguese (O Diário do Céu). The aforementioned Brazilian university offered in-service specialization courses to several elementary school teachers in the last few years (2018–2023), enabling them to interact with the dairy and understand key aspects of its methodology. Before using them, the Brazilian version was adapted to suit geographic local coordinates in the southern hemisphere—an opportunity for teachers in training to incorporate astronomical concepts into their planning. Throughout the academic year, students filled out their diaries on a daily basis. The Science Education Graduation Program at UNESP, along with teachers and researchers, acknowledged the value of this strategy and shared the data collected to be used in teaching courses at the masters and doctoral levels. Current studies on this methodology have now showed that the Diary of the Sky is a powerful and efficient tool for working introductory astronomy concepts with elementary students and training their respective teachers.

Authors: Kota Srividya Durga , Den-Besten Jacinta , Lazendic-Galloway Jasmina , Sharma Manjula Devi
Published: October 2024

Student engagement is a multifaceted construct having different dimensions: cognitive, behavioural, and emotional. Despite its centrality in learning and learning outcomes, student engagement has proven difficult to measure. Furthermore, it is under researched in undergraduate sciences, including physics. The aim of this paper is to present the development, validation, and evaluation of a survey which measures student engagement in physics laboratory learning; the Science Student Laboratory Engagement Questionnaire (SSLEQ). The survey measures undergraduate students’ cognitive, behavioural, and emotional engagement while doing experiments. Items from ASLE (ASELL Student Learning Experience) and AEQ (Achievement Emotions Questionnaire)-Physics Prac were adapted in developing this survey. The items for cognitive engagement are about motivators underpinning understanding of content and development of skills. The items for behavioural engagement query the resources provided such as experimental lab notes and demonstrators’ help. For emotional engagement, items explored positive and negative emotions. Confirmatory factor analysis and descriptive statistics conducted with a sample of 308 first year physics students confirm the reliability and internal validity of the survey for the purposes. This survey was evaluated with the first year physics students to compare engagement with students who experienced a face to face laboratory session before moving to online and students who experienced only online laboratory sessions. This survey can now be used in other contexts providing academics with measures of three types of engagement for use in science courses to positively influence students’ engagement with laboratory exercises.
New Metrics for Analysing Multiple-choice Questions
Authors: Warren Diana , Joshua Pople , Agarwal Rashika
Published: October 2024

While the ideal of constructive alignment in curriculum is well established, and the importance of evaluating learning and teaching is well known, evaluating assessments remains a complex task and gaps can arise between learning outcomes, learning activities and assessments.
Our study outlines an innovative way of analysing multiple-choice question (MCQ) examinations, which reveals possible weaknesses in the examination design and gaps in the alignment of curriculum. Individual examination questions are analysed through traditional metrics of the Discrimination Index (DI) and Difficulty Index (DIFF), combined with two novel metrics called the Grade Inversion Score (GIS) and Association with Total Score (ATS).
Focusing on examination marks from a data science examination from The University of Sydney, we perform two investigations. First, we identify poorly designed questions using DI, DIFF, GIS and ATS. Second, as multiple questions arise as deficient in these metrics, we explore specific areas in the curriculum where there may be misalignment of course material with the learning outcomes.
Our analysis provides a simple visual way for examiners to inspect the validity of an examination design and encourages an evidence-based approach to exploring curriculum alignment using multiple-choice assessments.

Published: October 2024

This research is based on many of university students who use e-commerce. The purpose of this study is to find out students' behavior in buying goods in e-commerce and whether they use the principles of maqashid al-sharia or not. The principles of maqashid al-sharia used are the maintenance of religion (hifz al-din), the maintenance of the soul (hifz al-nafs), the maintenance of reason (hifz al-‘aql), the maintenance of offspring (hifz al-nasl), the maintenance of assets (hifz al-mal), and the maintenance of the environment (hifz al-biah). This research is qualitative research with a phenomenological abbreviation. The sampling technique in this study is purposive sampling. This sample of research totaled 45 1st level students of Sultan Ageng Tirtayasa University. The results of the study show that students have not fully used the principles of maqashid sharia in the use of e-commerce, so students behave consumptuantly. In the principle of religious protection, it is known that not all students buy goods with the intention of worship, in the principle of preserving reason, students cannot decide properly the priority of the goods to be purchased, on the principle of spiritual care, students cannot resist the lust to buy goods that are by the usefulness, on the principle that the descendants of students have not been able to save money for the future, In the principle of assets, students were found to use the pay later feature. And on the principle of protecting the environment, students still need education in the recycling system of goods that have been purchased.

Published: October 2024

The human body is an extremely intricate work of art, with systems and organs interacting to create what has been acknowledged as life. Among these intricate relationships, one of the most fascinating and significant is the one that has been recently discovered between the gut, the brain, and the heart. This discovery has potentially changed our fundamental reductionist, positivist and more precisely biochemical understanding of higher consciousness, wisdom intelligence etc, paving way for a more holistic comprehension which includes philosophical and epistemological analysis. More importantly, such changed paradigm, challenges the accepted dualisms and invites serious research to explore the interconnectedness of mind, body, and emotion. However, these discoveries sparked a surge of discussions among diverse Muslim scholars and researchers who seek to understand the Qur'anic concept of heart-interceded wisdom, as well as the reasons why the Qur'an insist and talks about heart as a reflection of man’s religiousness or piety. It is important to keep in mind that science and the Qur'an are two different discipline each with their own set of argument and approaches. For instance, science is an always changing discipline due to technological innovations while, the teachings of the Qur'an are constant, ageless, occasionally metaphorical or allegorical. In the light of this intricate landscape, science and the Qur'an may either support or challenge each other on various matters. Therefore, it is imperative to note that scientific knowledge should not be regarded as the ultimate source for comprehending the Qur'an. Nonetheless, many individuals explore scientific findings to deepen their faith and their comprehension of the Qur'an. So, in this exploratory article, we will delve into the heart-gut-brain relationship, its scientific underpinnings, and the implications it holds for our understanding of Qur'anic teachings, health, emotions, and consciousness.

Published: October 2024

Due to the wide range of handwriting styles amongindividuals and the low image quality of the handwritten text, accurate handwriting detection has been a difficult challenge incomputer vision. This is because static feature analysis of the text imagesis frequently insufficient to account for these factors. The accuracy of recognizing different handwriting patterns has recently progressively increased because of the introduction of machine learning, particularly convolutional neural networks (CNNs). This study uses various filter sizes to create a deep CNN model to increase the handwritten digit recognition rate. The proposed model's multi-layer deep structure includes a fully linked layer (also known as a dense layer) for classification and one convolution and activation layer for feature extraction. The proposed methodology has an average classification accuracy of up to 99.5% on the MNIST dataset.

A novel approach is presented to address the prediction challenge in domestic solid waste generation through the application of machine learning techniques. To overcome the limitations inherent in capturing intricate temporal patterns faced by conventional Long Short-Term Memory (LSTM) models de- signed for time series forecasting, an enhanced variant, termed e-LSTM, is introduced. This model incorporates crucial enhancements to rectify standard LSTM shortcomings. Introducing a hybrid activation function, SigmoRelu, bolsters the model’s capacity to grasp complex time series patterns. Furthermore, the RAdam optimizer is employed to optimize the learning process and improve convergence. Dropout layers are seamlessly integrated within the LSTM architecture to counter overfitting, ensuring robust generalization to novel data. A series of comprehensive experiments is conducted to compare the performance of the e-LSTM model against standard LSTM and GRU models, showcasing its noteworthy advancements. Notably, the e-LSTM model demonstrates superior predictive accuracy in forecasting waste generation compared to standard long short-term memory (LSTM) and gated recurrent unit (GRU) models. In essence, the proposed e-LSTM model represents a significant stride in domestic solid waste prediction, effectively mitigating the limitations of traditional LSTM models. The synergistic integration of SigmoRelu activation, RAdam optimization, and dropout mechanisms results in a resilient and accurate predictive framework. Empirical results affirm the model’s superiority, establishing it as a valuable tool for waste management applications and decision-making processes.

Concrete is a widely used material in the construction industry. Rice husk ash and coal bottom ash are by-product materials chosen to alternate the use of cement and sand in concrete production. Concerns about the long-term performance of seawater concrete structures incorporated with RHA-CBA have been obstacles to the developing uses of sustainable concrete due to the scarcity of knowledge and test data. Thus, the long-term performance of seawater concrete consisting of RHA as cement replacement and CBA assand replacement on compressive strength and carbonation was evaluated in this study. To accomplish the study's goal, existing specimens aged 1 year and 4 months, and 2 years with different mixture series were used. In the mixture, seawater was utilized to fully replace freshwater, along with 10% RHA used to replace cement. Additionally, 10% to 100% CBA replaced the sand with a 10% increment. The specimens consisted of 68 cylindrical concretes in 100 × 100 mm and 100 × 200 mm exposed to indoor environmental conditions. Compressive strength and carbonation tests were performed to assess the strength and durability of the concrete. The results indicate that the concretes' strength grows insignificantly in the atmospheric environment within exposure age. Aftera prolonged period, the specimen's strength development reduces as the amount of CBA in the concrete mixture increases. Meanwhile, test results revealed that RHA-seawater concrete containing CBA exhibited minimal carbonation after 2 years of aging. Higher incorporation of CBA in the concrete mixture leads to a greater carbonation rate, reducing the concrete’s alkalinity. The findings of this study contribute to the understanding and advancement of long-term performances of sustainable concrete materials for construction practices.

Introducción. La dilatación endoscópica es una opción terapéutica eficaz en el tratamiento de estenosis y trastornos motores del esófago. Para su realización es esencial conocer la etiología y la anatomía de la lesión y tener experiencia clínica; estos factores determinan la indicación y el desarrollo del procedimiento. El objetivo del presente estudio fue reportar la experiencia en el manejo de pacientes con estenosis esofágica en un centro de referencia de enfermedades digestivas, en Bogotá, D.C., Colombia.
Métodos. Se realizó un estudio descriptivo, de cohorte retrospectiva, en el que se evaluaron los pacientes llevados a dilatación esofágica por el Servicio de Gastroenterología, desde enero de 2021 hasta junio de 2023. Se incluyeron todos los pacientes mayores de 18 años con estenosis esofágica de cualquier etiología o acalasia.
Resultados. Se identificaron 27 pacientes, 92,6 % hombres. La etiología más prevalente fue la estenosis por cirugía previa (40,7 %), seguida de acalasia (29,6 %), reflujo gastroesofágico (18,5 %) y enfermedades inflamatorias (11,1 %). La regla “del tres” fue utilizada con seguridad en las estenosis postquirúrgicas y pépticas. La mayoría de las dilataciones (81,5 %) fueron exitosas y se presentó una única complicación de perforación esofágica.
Conclusión. La dilatación endoscópica es un procedimiento seguro para el tratamiento de la estenosis esofágica y la acalasia. La correcta indicación del procedimiento, el tipo de estenosis, la elección adecuada del dilatador y la experiencia del profesional son aspectos cruciales para la efectividad de esta técnica y para la detección y manejo de las posibles complicaciones.

Tujuan Praktik Profesi Keguruan Terpadu (PPKT) adalah mengajar dan mengabdi di lingkungan sekolah, masyarakat dan lembaga. Pelaksanaan program ini berlokasi di Desa Ikhwan, Kecamatan Dumoga Barat, Kabupaten Bolaang Mongondow, Provinsi Sulawesi Utara, mulai tanggal 17 Agustus hingga 5 Desember 2023. Peserta dalam program ini berjumlah 17 orang. Metode yang digunakan adalah metode PAR dan ABCD. PAR (Penelitian Tindakan Partisipatif) merupakan suatu metode penyelesaian masalah dan pemenuhan kebutuhan masyarakat. Sedangkan metode ABCD (Asset Based for Community Development) merupakan metode yang digunakan untuk mengembangkan masyarakat melalui potensi atau aset yang dimiliki masyarakat itu sendiri. Hasil dari pengabdian ini menggambarkan adanya peningkatan kompetensi siswa di sekolah. Dampak yang dirasakan dapat dilihat dengan memiliki nilai dan prestasi yang baik di akhir studinya. Selain itu, masyarakat sekitar juga merasakan dampak tersebut dengan adanya pengajian baik membaca Al-Qur’an maupun bimbingan belajar. Untuk itu, program-program tersebut dapat mendorong perkembangan Pendidikan di Desa Ikhwan. Namun, kendala-kendala yang terdapat dalam pengabdian ini beragam. Mulai dari akses internet yang kurang memadai, motivasi peserta yang masih belum antusias terhadap program ini, dan kurangnya kolaborasi dengan masyarakat sekitar. Rencana tindak lanjut pada program PPKT ini adalah menjadikan desa Ikhawan sebagai Desa binaan oleh Fakultas Tarbiyah dan Ilmu Keguruan IAIN Manado sehingga desa ini berkembang dan dapat bersaing dengan desa-desa lain.  Harapan pada kegiatan selanjutnya adalah terlaksananya program-program berkelanjutan di Desa Ikhwan Kecamatan Dumoga Barat sesuai dengan topik yang terjadi dan yang dibutuhkan

Modelo para la toma de decisiones en atención odontologica: descripción y puesta a prueba de un modelo de intervención a nivel local
Authors: Mulbany P. , Bordoni N.
Published: October 2024

Abstract Objective: To describe a model to analyze dental care in a local geographical location in order to facilitate decision making related to care, based on scientific evidence. Methodology: The methodology includes (a) model design (MI) and (b) its testing application in a municipality (capital of the province). (a) The suggested model, built from a strategic approach, includes three stages (MM). MM1 (identifying) consists in the identification of problems through the collection of primary and secondary data. MM2 (analytic) related to the quantitative and qualitative analysis of the collected data. From the analyzed and prioritized information, the MM3 (propositive) makes recommendations in the social, legal-administrative, epidemiologic, perceptual and investigative areas. (b) The testing application of the model included the identification, analysis and prioritization of the problematic focuses arising from census data, statistics from health services and current programs. Data were processed with an explicative matrix and Hanton´s formula. A SWOT analysis (internal and external) made it possible to make suggestions and their potential transfer to health and education decisions. Results: (1) Testing the model in a local territory base (municipality) allowed the quick identification of problems in dental care and the integration of the collected information. (2) The model facilitated the translation of dental status into local reach health and educational activities, with possible impact on the health of the covered population. Conclusions: The MI can be applied in a short time and used to get timely information for decision making in a local area.
