Authors: GALCHU Tsegaye Udesa , WONDATER Wondewsen Bekele
Published: December 2024

The study was conducted in the Bule district of Gedeo zone in southern Ethiopia to assess the available feed resources for sheep fattening and their chemical composition in backyard sheep fattening operations. A reconnaissance study identified the main sources of feed, followed by a multi-stage sampling procedure to select kebeles and households involved in sheep fattening. Six kebeles were specifically selected based on sheep population, experienced fatteners and accessibility. A total of 126 households were randomly selected for the study. The main food sources included natural pasture, stubble pasture, forage, bamboo leaves, enset (Ensete ventricosum), crop residues, desho grass (Pennisetum pedicellatum), tree alfalfa, kitchen residues and mill products. Feed samples were taken for laboratory analysis, and the average values for dry matter (88.3%), ash (10.71%), organic matter (77.25%), crude protein (11.21%), neutral detergent fibers (60.2%), and acidic detergent fibers yielded (39.42%) and acidic detergent lignin (10.22%). Tree alfalfa (26.06%), mill products (16.11%), green fodder (13.88%), and bamboo leaf (12.45%) had the highest crude protein content. Bamboo leaves (21.15%), forage (15.17%), and stubble pasture (12.36%) provided suitable ash levels for mineral intake. However, concerns arise regarding fiber content in crop residues, grazing practices, and bamboo leaf quality, affecting feed intake, digestibility, and absorption. Promising feeds such as alfalfa, mill products, and forage boost high protein content, but better fiber management is essential for feeds with excessive fiber. Tailored feeding strategies, enhanced feed conversion, and thorough training for sheep fatteners are pivotal to address these challenges.

This article analyzes the relationship between education and social inequality, highlighting how socioeconomic disparities impact access, retention, and educational success. Considering the classroom as a reflection of broader social dynamics, the study examines how inequalities manifest in this environment and how teaching methods can contribute to either reproducing or mitigating these disparities. A literature analysis is conducted, based on the contributions of authors such as Bourdieu (1998), Freire (1996), Saviani (2013), Santana (2010), and Skliar (2014). The research identifies that inclusive teaching practices, involving active student participation, are essential for reducing educational inequalities. By adopting methods that recognize the diverse needs of students, these practices have the potential to transform the classroom into an equitable space. The analysis suggests that overcoming social inequalities in education requires adopting a pedagogical approach that values diversity and promotes inclusion, as well as empowering educators to address the specific needs of each student. The study also emphasizes the crucial role of public policies in promoting inclusive education and equitable access to quality education. Well-implemented policies can have a significant impact on creating conditions for all students, regardless of their socioeconomic background, to have equal learning opportunities. The research highlights the importance of ensuring that educational policies are truly effective, with proper allocation of resources and support for teacher training. Finally, the article concludes that inclusive education cannot be achieved without collaborative efforts from different societal agents, including governments, schools, families, and the community. The implementation of public policies focused on equity, combined with pedagogical practices that respect and value differences, is essential for promoting a more just and accessible education. Continuous research is also recommended to assess the impact of these practices and policies, with the goal of strengthening strategies that combat social inequalities in the educational system.

Authors: Antony Farizal , Ja'far A. Kumedi
Published: December 2024

Telephone marriages have become a controversial issue in Islamic family law in the modern era. Various views have emerged from scholars and schools of thought regarding their validity, particularly concerning the essential pillars and conditions for marriage, such as the offer and acceptance (ijab kabul), the presence of a guardian (wali), and witnesses. Some scholars permit telephone marriage in emergency situations with specific conditions, while others reject it due to the risks of mistakes or deception. Cases in Muslim countries indicate that this practice occurs, but it requires validation from local sharia authorities. Despite differing opinions, the conditions of sharia remain essential for both direct and remote marriages. The research method used in this study includes qualitative analysis of relevant Islamic law literature, interviews with scholars and legal practitioners, and case studies in several Muslim countries that have implemented remote marriages. With the advancement of technology changing social interactions, it is crucial for Islamic law to adapt to these new contexts without overlooking sharia principles. Therefore, in-depth studies and clear fatwas from Islamic legal authorities are necessary to ensure the validity and legal protection for couples who marry electronically.

INTERNATIONAL SECURITY AND ENVIRONMENT: TOWARDS AN ECOFEMINIST APPROACH
Authors: Çoban Oran Filiz
Published: December 2024

Since the perceptions of threats have been revised and multiplexed across time, each theoretical tradition within International Security Studies has interpreted environmental threats and security very differently, advocating competing standing points to answer the essential questions of who or what is to be secured and what is to be secured against. Despite the diversity of academic studies on environmental security, more systematic work still needs to be done to explore the linkage between ecofeminism and security. Thus, this study firstly exhibits the evolution of different approaches to environmental security and consequently shows how the lens of ecofeminism provides transformative insight into the human and nature relationship for planetary security and justice.

Published: December 2024

Objectives: To evaluate the effectiveness of current communication practices and the understanding of technicians regarding written prescriptions.
Methodology: This Questionnaire based cross-sectional study was conducted in Lahore, from Aug 2023 to May 2024, to assess communication quality between dentists and dental technicians. The sample consisted of 50 dental technicians currently employed in ten different private and public dental laboratories in Lahore, Punjab. The selection of participants was carried out using non-probability convenient sampling. Undergraduate students pursuing dental technology were excluded from the study to maintain a focus on experienced professionals who actively participate in dental restoration processes. Data were collected using a modified standardized questionnaire, including items on demographics and communication quality. Data was collected, reviewed for completeness, and analyzed using SPSS v24.
Results: Most dental technicians (n=38, 68%) possess a BSc degree in dental technology with work experience ranging from 1 to 45 years. Communication preferences varied notably across workplace settings. About 46% (n=23) of the technician favored direct communication. There was a significant difference in communication modes between these settings (p=0.001), with a preference for personal visits, particularly among technicians from teaching institutes (n=23, 88.5%). The majority (n=42, 84%) reported positive receptivity from dentists, and 62% (n=31) indicated that communication was encouraged, particularly in teaching institutes. Issues regarding blank prescription cards were mixed, with 36% (n=18) never receiving them and 50% (n=25) consulting clinicians in such cases. Only 36% (n=18) of technicians felt they received sufficient information.
Conclusion: Most technicians prefer direct communication from dentists, particularly in teaching institutes, compared to those in commercial labs who favor phone calls. A major concern was the lack of sufficient information and blank patient prescriptions from dentists. Addressing these gaps through standardized protocols, modern digital tools, and enhanced training can improve patient outcomes.

Globalny język LGBTQ+ w polskich narracjach o tranzycji
Authors: Chojnicka Joanna
Published: December 2024

Przedmiotem artykułu jest język narracji o tranzycji w polskich mediach społeczno-ściowych, rozumiany jako efekt negocjacji między globalnym językiem LGBTQ+ a lokalnymi kulturowo dyskursami o płci i seksualności. Tekst składa się z dwóch głównych części. Pierwsza część oferuje krótki przegląd istniejącej literatury przybliżającej historię polskiego dyskursu o tranzycji od lat sześćdziesiątych i siedemdziesiątych dwudziestego wieku, aż do momentu pojawienia się mediów społecznościowych. Emblematyczna w tej historii jest zmiana dominującej terminologii – odejście od form transseksualizm/transseksualność i rozpowszechnienie się formy transpłciowość – i towarzyszące jej przeobrażenia w postrzeganiu tego zjawiska: od jednostki chorobowej po kategorię polityczną i tożsamościową. Druga część artykułu, oparta na badaniach własnych, skupia się na procesie kształtowania się dyskursów o transpłciowości i tranzycji w polskich mediach społecznościowych. Proces ten został podzielony na dwa główne etapy. Etap pierwszy, który można nazwać „Transnet 1.0”, to czas anonimowych, wykorzystujących głównie medium języka pisanego blogów, a etap drugi – „Transnet 2.0” – to czas multimedialnych (audiowizualnych) produkcji publiko¬wanych na takich platformach, jak Facebook, YouTube czy TikTok. Empiryczną część artykułu zamyka propozycja opisu praktyk wielojęzycznych stosowanych na polskich kanałach YouTube zajmujących się tematyką transpłciowości, aby pokazać, jak polska społeczność trans buduje język narracji o tranzycji, czerpiąc z „globalnego socjolektu LGBTQ+” (Bassi, 2017) w strategiczny, świadomy, i kreatywny sposób. Sugeruję interpre¬tować badane przeze mnie praktyki wielojęzyczne jako ilustrację umiejętności nawigowania między dyskursem medycznym a tożsamościowym, między globalnymi trendami i lokalnymi tradycjami, oraz między zwięzłością angielszczyzny a produk¬tywnością polskiej gramatyki.
Are the Queer Movements in India Inclusive?: Explorations of Hierarchies within the Queer Community
Authors: Sarkar Swakshadip
Published: December 2024

India has seen progress in the laws and legislations granting rights to queer people in the last ten years. This resulted from decades of activism starting in the late 1980s. However, equal rights and opportunities have not been extended to all queer individuals, revealing fractures within the movement. In this context, this article explores the issues within the queer movements that have led to the hierarchisation of priorities that the movements have advocated for. Historically, queer activism has been dominated by the development sector, operating within neoliberal frameworks and global funding regimes. This has led to the prioritisation of certain issues due to the privileged backgrounds of those leading the NGOs, resulting in the exclusion of intersectional sexual subaltern groups who do not fit the neoliberal ideals of professionalism and corporatisation. The language used within queer movements, often shaped by global discourses, has also created barriers. Terms like men who have sex with men (MSM) and transgender, used to secure funding, privilege those with access to such terminology, leaving others marginalised. This centralisation of power persists today, exemplified in issues like advocating for same-sex marriage, which reflects homonormative ideals that reinforce existing class and caste structures. Meanwhile, critical issues – such as challenging the Transgender Persons (Protection of Rights) Act, 2019 or advocating for horizontal reservations for transgender individuals – are sidelined. To address these disparities, this article suggests that a bottom-up approach in queer advocacy is necessary to advocate for the rights of intersectional sexual subalterns, with some emerging queer movements beginning to reflect these ideals. Further, there needs to be more focus on rural and subaltern queer practices and advocacy in addition to forging alliances with other social movements – such as those on caste, class, and disability – to create safer spaces and inclusive queer movements.

Published: December 2024

Abstract. The LiDAR on the iPad device can be used for surveying and mapping. However, the accuracy and precision of the LiDAR scanner on the iPad are not as high as the LiDAR system on Terrestrial Laser Scanning (TLS), with a more limited range and smaller coverage area. Still, the LiDAR sensor integrated into the iPad has advantages when compared to professional LiDAR systems, including the iPad LiDAR as a low-cost portable 3D scanner, dynamic portability, speed, easy use at close range so that it can be used to scan objects with high density and can reach areas/parts of objects that are difficult to be covered by TLS. The 3D modelling method using iPad LiDAR is a solution for building 3D models.Since iPad’s point cloud data is not integrated with the global coordinate system, a georeferencing process is necessary to produce DEM (Digital Elevation Model), which will be used to define customary zones in Panglipuran Heritage Village. The georeferencing process is carried out by transforming the iPad’s LiDAR coordinates system to the global reference coordinates resulting from GNSS measurements. The scanning strategy must be well arranged. In addition, good control point design determines the quality of control point transformation results into a global reference coordinate system.This research contributes to obtaining an alternative low-cost 3D mapping method for cultural conservation areas using LiDAR technologies. This method is inexpensive but still considers geospatial quality aspects so it can be used for the decision-making process in spatial planning of cultural regions.

Published: December 2024

Abstract. This study explores low-cost photogrammetry solutions for surveying confined underground spaces, focusing on Tomb 7 at the UNESCO World Heritage Site, Tombs of the Kings in Paphos, Cyprus. The research, part of the ENGINEER project, compares traditional photogrammetric methods using frame cameras against a 360° multi-lens camera. The aim is to identify reliable, low-cost methods for 3D documentation of archaeological sites, which can be used for structural analysis and systematic monitoring.Three photogrammetric acquisition methodologies were tested: handheld with frame camera, standard with frame camera, and relaxed with 360° camera. The study evaluates the accuracy of these acquisition methods by comparing dense point clouds generated from each dataset against a reference dataset obtained via terrestrial laser scanning (TLS). Metrics such as cloud-to-cloud distance, roughness, and point cloud density were used for comparison.Results indicate that while the 360° camera offers ease of use and high data density, it also introduces more noise and variability. Traditional methods, though more time-consuming, provide more consistent and accurate results. The findings suggest that combining both approaches could optimize data quality and acquisition efficiency, making the 360° multi-lens camera a viable low-cost photogrammetry option for heritage documentation.
Assessing the effectiveness of LiDAR-based apps on Apple devices to survey indoor and outdoor medium sized areas
Authors: Treccani Daniele , Adami Andrea , Fregonese Luigi
Published: December 2024

Abstract. In 2020, Apple started to include a LiDAR (Light Detection And Ranging) sensor on its high-end mobile devices. Since the introduction of the sensor, a large number of apps exploiting it have populated the iOS App Store. Therefore, Apple devices with a LiDAR sensor have seen increasing applications for efficient, low-cost spatial analysis and 3D modeling of small objects, rooms, and small areas. In this context, it becomes interesting to understand the potential of this sensor exploited by existing apps for surveying not only small areas, but also medium-sized indoor and outdoor areas. The study here presented evaluates the effectiveness of five iOS LiDAR-based apps for surveying medium-sized indoor and outdoor environments using Apple devices. The research used two test areas—a university building corridor (indoor) and a narrow urban street (outdoor)—to examine the performance of each app against a reference dataset from a Terrestrial Laser Scanner (TLS). The study explores each app’s capabilities, considering settings, point cloud density, accuracy, and usability across two survey path strategies: a closed loop and a zigzag. Results highlight that while mobile LiDAR apps on Apple devices facilitate low-cost, fast, accessible surveys, they exhibit in some areas errors on the order of 10 centimeters, while in others, on the order of 1 centimeter. The final result was very much influenced by how the raw data was handled by the apps, and it was noted that for medium-sized areas (both indoor and outdoor) the apps that produced better results were the ones benefitting from loop-closure to reduce trajectory drift. Based on the results, this approach could support urban management, road assessments, and other applications where rapid data capture is required and medium accuracy is sufficient.

Authors: Trump Nicholas W. G.
Published: December 2024

Abstract. This paper presents a novel solution to a reality capture and 3D contextual mapping problem. A wearable camera rig was designed to capture photographic information of existing trails within North Vancouver, British Columbia, Canada. High-resolution video and 360° images were captured for 3D reconstruction models and the creation of an online virtual tour environment. Pathway width of the existing trails was extracted using a linear feature extraction tool to create detailed base map drawings for the client. A computer vision model was trained to detect tree species from images of tree bark. A summary of the stages of the project, lessons learnt from the use of photogrammetric (Structure from Motion) methods, suggested improvements to the computer vision model, and thoughts on the direction of reality capture methods within the infrastructure sector are given.
Exterior Orientation in a Box: Cost-Effective RTK/IMU-Based Photo Geotagging
Authors: Wieser Martin , Verhoeven Geert , Wild Benjamin , Pfeifer Norbert
Published: December 2024

Abstract. This paper presents a small, cableless and cost-effective (circa € 500 in 2022) device that embeds an RTK-enabled GNSS receiver and IMU in a 3D printed case to record the exterior orientation of photos via the camera's hot shoe. This hardware solution was developed within the academic graffiti project INDIGO to enable a faster and more robust exterior orientation (via incremental SfM) of the hundreds of weekly acquired graffiti photographs. The device relies solely on commercially available open-source development components that require only minimal knowledge of electronics. Moreover, it is small enough not to disturb the photographer but still provide constant visual feedback about the device's overall and positional solution status. To realistically test the achievable positional and rotational accuracy, we acquired a dense network of graffiti photos in INDIGO's test area. This test showed that the device provides centimetre-accurate photo positions and one-degree accurate pitch and roll values. The heading or yaw is probably only usable to some extent since it primarily relies on magnetometer measurements, which get quickly disturbed in an urban environment. In addition, the test revealed that the camera's internal IMU can provide roll and pitch values with sub-degree accuracy.
Automatic upgrade of 3D building models to LoD3 using 3D Point Clouds and Grounding DINO
Authors: Yarroudh Anass , Kharroubi Abderrazzaq , Jeddoub Imane , Billen Roland
Published: December 2024

Abstract. The advancement of urban digital twins depends on the accurate representation of 3D city models, particularly Level of Detail 3 (LoD3) models, which incorporate detailed façade features essential for urban planning applications. However, generating LoD3 models is challenging due to the complexities of semantic segmentation in 3D point cloud data and the high resource demands of traditional methods. This paper presents an automated methodology for upgrading existing Level of Detail 2.2 (LoD2.2) building models to LoD3 using mobile mapping point cloud data and the Grounding DINO model. The approach begins with extracting façade surfaces from LoD2.2 models while maintaining geometric integrity. Point cloud data is then transformed into a 2D image format to facilitate the application of Grounding DINO, which accurately detects and segments façade elements such as windows and doors. The identified features are re-integrated into the 3D model, resulting in an enhanced LoD3 representation. This methodology demonstrates effectiveness and scalability, providing a practical solution for improving urban digital twins with detailed and reliable building models.
A refined 3D reconstruction method for irregular ancient buildings
Authors: Zheng Xinting , Duan Yansong
Published: December 2024

Abstract. The refined three-dimensional (3D) reconstruction of ancient buildings using unmanned aerial vehicles (UAVs) is a crucial task in cultural heritage preservation. However, the complex structure, diverse shapes and non-regularity of ancient buildings make it difficult for traditional 3D reconstruction methods to fully cover all the details, resulting in poor quality reconstruction models. Therefore, this study proposes a novel 3D reconstruction method tailored for irregular ancient architecture, which adopts a "structural surface" guided strategy, and plans routes through the idea of "structural surfaces segmentation and then designing the routes", so as to obtain a high-resolution image set, and to ensure that the reconstruction model's fineness and completeness. Additionally, to tackle the slow speed and time-consuming nature of traditional modeling algorithms in establishing image adjacency relationships, this paper presents a method that utilizes flight path information to build these relationships. To validate the effectiveness of the proposed method, the Yellow Crane Tower in Wuhan, Hubei Province, China, was selected as a case study. Results indicate that the proposed method successfully enables the refined reconstruction of the Yellow Crane Tower, providing significant insights for the 3D reconstruction of irregular ancient buildings.

Çalışmada, dijital dönüşümün eğitimde fırsat eşitliği sağlama potansiyeli vurgulanırken, aynı zamanda yeni eşitsizlikler yaratma riskine de dikkat çekilmektedir. Türkiye’de kırsal bölgelerde ve düşük gelirli hanelerde yaşayan öğrencilerin dijital eğitim kaynaklarına erişimde karşılaştıkları zorluklar, eğitimde fırsat eşitliğini olumsuz yönde etkilemektedir. FATİH Projesi ve Eğitim Bilişim Ağı (EBA) gibi projeler, Türkiye’de dijital dönüşüm sürecinde önemli adımlar olarak değerlendirilmektedir. Bu projeler, öğretmenlerin dijital okuryazarlık ve pedagojik becerilerini geliştirmeyi hedeflemekte ve öğrencilere dijital eğitim kaynaklarına erişim imkânı sunmaktadır. Bununla birlikte, projelerin etkinliğinin artırılması ve dijital altyapının tüm bölgelerde eşit şekilde dağıtılması gerektiği vurgulanmaktadır. Yükseköğretimde dijital dönüşüm de bu bağlamda önemli bir rol oynamaktadır. COVID-19 pandemisi sürecinde uzaktan eğitim platformlarının geliştirilmesi ve teknolojik altyapının güçlendirilmesi, üniversitelerde dijital dönüşümün hızlanmasına katkı sağlamıştır. Yükseköğretim Kurulu (YÖK) tarafından başlatılan “Yükseköğretimde Dijital Dönüşüm Projesi”, öğretim elemanlarının dijital becerilerini geliştirmeyi ve üniversitelerin dijital altyapılarını iyileştirmeyi hedeflemektedir. Sonuç olarak, dijital dönüşümün eğitimde fırsat eşitliğini artırma potansiyelinin tam anlamıyla gerçekleştirilmesi için dijital uçurumu azaltmaya yönelik politikaların ve stratejilerin etkili bir şekilde uygulanması gerekmektedir. Eğitimde dijital dönüşümün sürdürülebilir ve kapsayıcı olması, dijital okuryazarlık becerilerinin geliştirilmesi ve dijital araçlara erişimin artırılması ile mümkün olacaktır.

Neste artigo, em que se pretende homenagear Basil Bernstein, no ano em que se comemora o centenário do seu nascimento, é feita uma particular referência à relação académica e pessoal que manteve com o Grupo ESSA (Estudos Sociológicos da Sala de Aula), da Universidade de Lisboa. Atendendo à área fundamental de investigação deste grupo – Investigação em educação científica – é também referida a forma como a teoria de Bernstein, nomeadamente a teoria do discurso pedagógico, se interligou com essa área, possibilitando o esbatimento de fronteiras, habitualmente existentes, entre campos de conhecimento tão distintos. Na última secção, e a título de exemplo, apresentam-se alguns dados empíricos de um estudo desenvolvido no âmbito do Grupo ESSA, que ilustra a citada articulação. Recorre-se a dois conceitos distintos da teoria de Bernstein, os conceitos de poder e controlo, assim como a duas relações sociológicas, fundamentais para uma aprendizagem científica eficiente: a relação entre o professor e os alunos e a relação entre discursos.
The evolving dynamics of natural versus artificial intelligence: An emergent framework for public health technology assessment
Authors: Tunalıgil Verda
Published: December 2024

The interaction between natural intelligence (NI) and artificial intelligence (AI) is increasingly significant as technology evolves. While NI has historically driven human progress, AI introduces new models in problem-solving and decision-making. This study explores the dynamics between these forms of intelligence and their implications for public health technology assessment. This review employs a multidisciplinary approach, including historical analysis, comparative case studies, and examination of ethical considerations, to assess the impact of AI relative to NI. Natural intelligence has traditionally addressed complex problems, but AI now enhances capabilities through data analysis and precision. While AI offers significant benefits across sectors such as health care, finance, and education, it also raises concerns about data privacy, ethics, and job displacement. In public health, AI can improve disease management and resource allocation, though challenges related to health disparities and data security persist. The integration of AI presents substantial opportunities but requires careful management of ethical and practical challenges. Maintaining a balance between leveraging AI and preserving human cognitive functions is crucial. Developing a prototype model to address current global public health challenges, based on the perspectives presented and the considerations discussed, could provide valuable additional insights into effective strategies for managing these complex issues worldwide. The future of AI involves integrating technological advancements with human intelligence to enhance capabilities while addressing ethical and practical issues. This balance will be key to advancing public health and other sectors effectively.

Purpose: The purpose of this study was to evaluate the financial performances of the six medical device companies among Fortune 500 companies before, during and after the COVID-19 pandemic.
Methodology: We first conducted ratio analysis by using liquidity, turnover, leverage and profitability ratios; then we conducted Wilcoxon signed-rank tests by using the calculated values of the financial ratios. We obtained the required data from the annual financial statements of the medical device companies among Fortune 500 companies. In the analyses, we took 2019 as the year before the COVID-19 pandemic, 2020 and 2021 as the year of the COVID-19 pandemic and 2022 as the year after the COVID-19 pandemic.
Results: The results of the study showed that the medical device companies among Fortune 500 companies were able to keep their financial performances steady when the COVID-19 pandemic began; they were able to increase their profits in the second year of the COVID-19 pandemic; and they were able to start using their assets more efficiently after the COVID-19 pandemic.
Discussion: The findings of the study suggests that the overall financial performances of the medical device companies among Fortune 500 companies were strong before, during and after the COVID-19 pandemic. The evaluation of the financial performances of the medical device companies among Fortune 500 companies before, during and after the COVID-19 pandemic may be beneficial for managers and policy makers in the medical device industry to determine the areas that requires to be strengthened in order to be better prepared for possible future pandemics and crisis periods.

Published: December 2024

The rise of online distance learning has necessitated investigations into its effectiveness across various educational contexts. This study examines the academic performance of students enrolled in technology education programs across three distinct learning modalities: synchronous, asynchronous, and blended. The study aims to determine if significant differences in academic performance exist among these modalities and how they vary across different assessment types (formative, performance-based, and examination). Forty-five students were equally divided into three groups, each experiencing one of the learning modalities. A non-parametric Kruskal-Wallis test was employed to analyze the academic performance data. The results indicated significant differences in student performance across the three learning modalities, particularly in formative assessments where blended learning yielded significantly higher scores compared to synchronous and asynchronous modalities. The superior performance in the blended learning modality was consistent across performance-based tests and examinations. Notably, the highest academic performance was observed in the students who engaged in blended learning and were assessed through performance-based tests. Asynchronous learning consistently resulted in lower performance across all assessment types. These findings suggest that blended learning may be a more effective pedagogical approach in technology education, facilitating enhanced academic performance compared to purely synchronous or asynchronous online learning environments.
