Authors: Taboer Mohammad Arif , Rochyadi Endang
Published: June 2024

Initial reading difficulties are a phenomenon that occurs almost every school year in elementary school. In response to this phenomenon, the services developed are remedial learning services. In its implementation, remedial learning services are still a debate. On the one hand, remedial services look more at the effectiveness of activity implementation, but on the other hand still do not answer the holistic needs of students. This research was developed with the aim of developing intervention strategies in serving the reading learning needs of students with reading difficulties without having to serve them in specialized classes. The subjects in this study were two students with initial reading difficulties in the third grade of one of the public schools in East Jakarta. This research method is a mixed method. In the first stage, an assessment of reading difficulties was carried out on students. Furthermore, the required strategy is developed and finally analyzes the effectiveness of the strategy used through visual graphs of the achievement of intervention results. The results of this study suggest that through the intervention strategies developed can provide opportunities to improve students' early reading skills. These results have an implication on the development of educational service models for students with beginning reading difficulties in improving beginning reading skills.

The Development of High-Performance Packaging Steels
Authors:   , Bennett Sean
Published: June 2024

The aim of this work is to create a new packaging grade of high strength steel for can-end applications. This new grade must have a yield strength of 650-750MPa, with a total elongation value of at-least 5% in all directions after double reduction rolling. The higher yield strength is required for downgauging, as well as being capable of withstanding the pressures in the retort process, while the ductility is required to form the rivet on the end to attach the ring pull to. The methods used to achieve this involved varying typical packaging alloying elements (such as silicon, phosphorous, and nitrogen), and simulating annealing cycles using a Gleeble 3500 heating simulator where annealing parameters (such as heating rate, soak temperature, and cooling rate), were changed. The purpose of these methods was to promote strengthening via solid solution strengthening, and/or via ferrite grain refinement, and/or secondary phase strengthening. Mechanical properties were assessed using a tensile tester and hardness tester, and microstructures were analysed using optical microscopy and software to obtain statistical information regarding grain size. It was found that when subjected to the commercial annealing cycle a high nitrogen containing chemistry achieved the desired mechanical properties outlined in the project aims. This is likely due to the solid solution strengthening effect of the large amounts of solute nitrogen. Intercritical annealing at 850°C does not lead to generation of secondary phase in the steel chemistries assessed in this body of work, and sometimes decreased the strength in some chemistries. Removal of the slow cool section from simulated intercritical annealing cycles led to negligible changes in Vickers hardness value as well as no microstructural changes either. It was found that packaging steels do not undergo significant amounts of grain refinement when an ultra-rapid heating rate of 200°C/s was used, nor when a 1,000°C/s heating rate was used.

The recent application of Virtual reality (VR) and Motion Tracking Technologies
(MTT) in physical rehabilitation is an emerging area addressing the insufficiencies of
conventional methods. In this review paper, we describe how VR and MTT interact with
each other and elaborate on their mutual capacities to improve treatment results in
physical rehabilitation. This problem can be specified as the limited effectiveness of
conventional rehabilitation methods in promoting patient motivation and engagement. VR
and MTT are emerging innovations; however, their combined utilization for rehabilitation
needs a detailed analysis to reveal their applicability and benefits. The primary
purpose of this review is to assemble recent studies on VR and MTT application in
physical rehabilitation, emphasizing the efficacy, specific domains where they can be
used, and the peculiarities of their application in clinical practice. A narrative
review method was employed for this paper, which covered a wide range of peer-reviewed
articles, clinical trials, and metaanalyses. A significant finding of this study shows
that VR and MTT, when used in combination, contribute to the substantial improvement in
patient outcomes in motor function, balance, and cognitive recovery. The article's
novelty is that it analyses the integrated use of virtual reality and mobile training
technologies in rehabilitation, thus revealing its potential to overcome the limitations
inherent in traditional therapies and ensure more intensive involvement and
individualized treatment. The empirical significance of this study can be helpful for
healthcare professionals and physical therapists who seek new ways and directions in
their work with patients. Scope of Further Investigations: In terms of future research,
this paper suggests the necessity of large-scale, randomized controlled trials to
identify standard protocols, explore long-term impacts of the integration, and
investigate applications in less-known rehabilitation domains. The authors emphasize
that successful implementation requires a collaborative effort between healthcare
professionals, engineers, and researchers to design appropriate protocols tailored to
individual patient needs.

Machine learning is a logical extension of automation using computer systems.
While a large number of different areas of human activity have been improved by
algorithmic software, a large number of other problems remain unsolved because creating
an algorithm for them is almost impossible. One of these fields is science. The
empirical approach is still main approach in achieving results, because for many studies
there is still no clear mathematical apparatus. Machine learning is the solution that
allows to save resources and speed up the research process. Conducting experiments
always leads to collecting data about the results. Machine learning algorithms allow to
use this information to build a model capable of predicting the results of experiments
or the properties of new compounds. Within the scope of this article, the effectiveness
of different algorithms, both standard and ensemble algorithms, is tested on the data
obtained from experiments with solute diffusion. As a result, the effectiveness data of
various algorithms were calculated using the formulas of root mean square error, as well
as mean absolute percentage error. An example and description of the process of building
different types of machine learning models are given.

This article addresses the issue of noise and drift in microelectromechanical
gyroscopes and their impact on measurement accuracy in engineering applications. The use
of a complementary filter is proposed to combine information from the accelerometer and
gyroscope to reduce inaccuracies. Research shows that the accelerometer has better
result repeatability, which is important for obtaining stable measurements. At the same
time, the gyroscope may be more effective in measuring translational movements. The
selection of sensor sensitivities and proper parameter tuning are crucial aspects. A
developed system is capable of effectively filtering and measuring the angle of an
object, and the use of a complementary filter improves measurement accuracy. The
proposed approach can be successfully utilized for accurately detecting the angle of
position of a measurement setup in defect inspection of underground pipelines.

Authors:   Department of Physics, University of Lampung, Bandar Lampung, Indonesia, Ginting Pariaman
Published: June 2024

The bio-foam in this study was made from biopolymers in the form of cassava starch, cellulose from corn stalks, and a binder polymer in the form of polyvinyl alcohol (PVA). The bio-foam was molded using the thermo pressing method at T = 150 °C and pressed for t = 3 minutes. Ag+ ions were added as an initial review of the physics properties of the bio-foam to serve as a reference for future antibacterial bio-foam manufacturing. Ag+ ions were produced using the electrolysis method from AgBr rods with an electric voltage of 15 volts. Then, the electrolyzed solution containing Ag+ ions was varied in concentration (12 ppm, 17 ppm, 22 ppm, 27 ppm). The ions were then coated on the bio-foam using the dip coating method and dried at room temperature. Along with the increase in the concentration of the Ag+ ion solution coated on the bio-foam, there was an increase in the bio-foam crystallinity with test values of 34.4%, 40.8%, 41.2%, and 42.6%, respectively. Based on these data, the crystallinity value of the bio-foam does not change significantly. It also aligns with the density test values, which tend to be constant with an average test value of 0.322 g/cm³. Furthermore, the concentration of the solution containing Ag+ ions did not influence the bio-foam's porosity properties, where the four samples tended to remain with an average value of 5.9%.

This research aims to determine the design of an Android-based distance and travel time information media simulation that is capable of providing location information regarding the location of airport service facilities by implementing the working system of a navigation tool, namely Non-Directional Beacon. The subject of this research is the area of the terminal, which will be included in the application, while the research object is the location of airport public service facilities that have been provided by the airport management. The research procedure used is adapting the research and development (R&D) method to the ADDIE method approach. The data source is reference distance information on the Map application, the Auto CAD application, and the Mapplic application. The type of data is quantitative data (direct measurements in the relevant field). The instruments used in data collection are the mapplic application and the auto CAD application. The data collection technique was carried out using trials and questionnaires. The data analysis technique used is black box testing. The results of this research found a linear regression equation, namely Y = 75.531X + 41.229, with an R2 value of 0.9941. For sample 1, the length of travel time required, namely by comparing the map distance of 278.787, the travel time based on the actual distance is 82.52, so to calculate the travel time required for the distance 82.52, namely 82.52 − 41.229 = 41.291/75.531 = 0.5466 or 0.55 minutes (with rounding). While the travel time for sample II with a map distance of 732 pixels and the actual distance is 732 pixels × 0.296 meters = 216,672 meters, then the travel time required is 216,672 meters − 41,229 = 175,443/75,531 = 2.3227 or 2.32 minute. From these calculations, it is compared with the results of the time and distance obtained based on the application developed, namely the design of the directional path in the terminal by first determining the origin coordinate point and destination coordinate point in the application developed.

Authors: Amirgholami Bahar , Masihi Sara , Tahmasebi Golshan , Samie Reza
Published: June 2024

Introduction: Fetal growth disorder is one of the most important factors in the morbidity and mortality of newborns. Investigating the factors and predicting them can be done through biochemical markers and sonography. The quality of the placenta was measured by measuring PAPP_A and free B_HCG and its quantity by examining the placenta by ultrasound. This study aimed to determine the correlation between fetal growth percentile and these three variables.
Methods: This prospective cohort study was conducted on 462 pregnant mothers in Ahvaz. The criteria of this study were singleton pregnancies, accurate knowledge of last menstrual date, non-smoking, no drug or alcohol consumption and consent to participate in the research exclusion criteria were fetal anomaly, chromosomal disorder and lack of ultrasound in the third trimester. PAPP-A and free B-HCG were measured in the 11–13 + 6 weeks of pregnancy, and then in the third trimester fetal placental thickness and fetal weight were measured by two-dimensional sonography. The data was analyzed using SPSS software version 26 as well as Pearson statistical logistic test and the results were analyzed.
Results: Out of the 462 fetuses none of them were under the 10% weight percentile. 187 fetuses were between 10%–50% of the weight percentile and 260 fetuses were between 50%–90% weight percentile and 15 fetuses were above the 90% weight percentile. The level of free B-HCG was significantly different in the three weight groups, the uppermost level of B-HCG was in the 90% weight percentile group (p-value = 0.008). The level of PAPP-A also correlated with the fetuses’ weight percentiles (p-value = 0.002). There was a positive and significant correlation between placental thickness in the third trimester in the three groups (p-value = 0.004) which means that with the increase in the thickness of the placenta, the fetus’s weight increases.
Conclusion: Based on this study, the measurement of placental markers and diameter helps predict birth weight and is expected to help in deciding the time and type of pregnancy termination.

Engagement strategies play a crucial role in ensuring engaged and high-quality online learning experiences. In this mixed methods study, we examined online students’ expectations and explored their experiences regarding online strategies of peer, instructor, self-directed, and multimodal engagement, using a survey and qualitative interviews. Our quantitative results indicated that instructor engagement strategies were perceived as the most important strategies to be employed in online courses, while peer engagement strategies were viewed as the least important. Qualitative findings suggested that although all four dimensions were perceived to be important and necessary, actual experiences of each contextually varied. In support of prior research, our study demonstrates the importance of the instructor in online courses and offers theoretical implications for online student engagement and practical implications for instructors, instructional designers, and other stakeholders in online education.

Authors: Martin Florence , Kumar Swapna , Ritzhaupt Albert , Polly Drew
Published: June 2024

Bichronous online learning is the intentional blending of asynchronous and synchronous online learning experiences. Twelve award-winning online instructors participated in interviews to discuss best practices they use, and benefits and challenges in bichronous online courses. When sharing best practices for bichronous online courses, award-winning online instructors explained how they combined best practices in asynchronous and synchronous online learning. Asynchronous online best practices included course design and structure, resources, and instructor presence; and synchronous online best practices focused on formats, activities, and content of synchronous sessions, and community-building. The best practices, benefits and challenges discussed in this paper have implications for instructors who currently teach in a bichronous online format or may be considering it in the future, and for instructional designers and administrators who work with faculty on offering courses in this modality. Based on the data, the intentional blending of synchronous and asynchronous components has a lot of potential to enhance students’ online learning experiences.
Learner perceptions of the feedback process in the online component of a blended course
Authors: Moni Anna
Published: June 2024

Despite extensive research on feedback models, there is still sparse empirical evidence of their validity and application in higher education learning settings, whether online, hybrid, or face-to-face. Understanding how a feedback framework, integrated in the instructional cycle, is perceived by the learners can provide empirical support about its intended purpose and effectiveness. Recent reviews of research on student perceptions of feedback in different learning environments have revealed the need to research feedback as a process with the use of a more solid methodological approach. The aim of the present descriptive survey study is to investigate learners’ perceptions of an established feedback model, a Matrix of Feedback for Learning (Brooks et al., 2019), in the asynchronous online component of an undergraduate blended course. More specifically, the impact of its application on learners’ encounters with three types of feedback (feed-up, feed-back and feed-forward) and three levels of feedback (task, process and self-regulatory) is explored. A 36-item survey, previously piloted and preliminarily validated, was used to explore learners’ perceptions (N=135) of the three feedback types and levels. Approximately 68% of responses showed that students recognized feedback and the possibilities to use and act on feedback as helpful to their learning. This present survey supports a line of research on feedback model validation in online learning environments while offering meaningful insights from the learners that can inform both course design and interventions to support engagement with feedback.
A Framework for Evaluating Online Degree Programs Through Student Satisfaction
Authors: Zhou Zikai , Rouse Sharon
Published: June 2024

Student satisfaction is a key indicator in evaluating any degree program's performance. In light of the vast difference between online and traditional degree programs, the factors that affect student satisfaction may vary across different courses. Based on the previous literature, this study explores the factors that may affect student satisfaction with online degree programs. A structured framework is proposed for evaluating online degree programs, including six big categories of factors and three outcome variables related to student satisfaction. Data were collected from an online degree program in a large public university to assess the underlying relationships and identify the key factors affecting student satisfaction. In addition, students’ self-regulated learning behavior was identified as the primary factor leading to the significant difference among the three outcome variables. The implications to school administrators and accreditation bodies were also addressed.
Towards Connectivism: Exploring Student Use of Online Learning Management Systems during the Covid-19 Pandemic
Authors: Liu Dapeng , Carter Lemuria , Lin Jiesen
Published: June 2024

The COVID-19 pandemic has had a profound global impact on students, necessitating a shift towards fully remote e-learning via digital learning management systems (LMS). Despite this significant shift, there is a paucity of research exploring how students of varying academic performance levels engage with e-learning resources. This study addresses this gap by leveraging self-regulated learning theory and connectivism theory to analyze 129,567 activity logs from an Australian public research university. These logs encompass the online learning activities of 313 students and provide insights into their utilization of course files, discussion forums, gradebook, and online quizzes. Our analysis reveals significant differences in how students of varying academic performance levels engage with these resources. We found that higher-performing students tend to view course files, view and create forum posts, and access online quizzes more frequently, suggesting a positive correlation between active engagement with these resources and academic performance. However, the frequency of gradebook views did not significantly differ among students of different performance levels, indicating that grade tracking may not be a strong determinant of academic success. These findings underscore the importance of active engagement with online resources in academic success and provide valuable insights for educators and institutions in designing online courses and strategies to support student learning. The study also highlights the need for further research to understand the nuances of student engagement with e-learning resources. The implications of these findings extend beyond the pandemic, contributing to the broader discourse on e-learning and academic performance.
Multifaceted challenges and opportunities: Chinese exchange students’ experiences in the U.S. transnational online learning ecology
Authors: Ren Xinyue , Zhou Yi
Published: June 2024

Transnational distance education has become an emerging trend in promoting academic collaboration and exchange during and after the pandemic. Guided by the learning ecology framework, we conducted mixed methods research by distributing an online survey to Chinese students (N=51) to collect quantitative and qualitative data. This helped us deeply understand their experiences and perceptions of a cross-cultural online learning environment in the United States. We applied multiple regression and thematic analysis to analyze quantitative and qualitative data. The merging of both types of data analysis indicated: the confirmation of the importance of English learning resources, the transformation of online learning practices, the insufficiency of students-to-instructors interaction, discordance of technological self-efficacy and the disadvantages of technology-assisted instruction, and discordance between the usefulness and difficulties of learning activities and assessments. We further discussed appropriate strategies and techniques to promote online teaching and learning excellence in transnational distance education.
Against Artificial Education: Towards an Ethical Framework for Generative Artificial Intelligence (AI) Use in Education
Authors: Swindell Andrew , Greeley Luke , Farag Antony , Verdone Bailey
Published: June 2024

The arrival of Generative Artificial Intelligence (AI) is fundamentally different from prior technologies used in educational settings. Educators and researchers of online, blended, and in-person learning are still coming to grips with possible applications of AI in the learning experience with existing technologies; let alone understanding the potential consequences that future developments in AI will produce. Despite potential risks, AI may revolutionize previous models of teaching and learning and perhaps create opportunities to realize progressive educational goals. Given the longstanding tradition of philosophy to examine questions surrounding ethics, ontology, technology, and education, the purpose of this critical reflection paper is to draw from prominent philosophers across these disciplines to address the question: how can AI be employed in future educational contexts in a humanizing and ethical manner? Drawing from the work of Gunther Anders, Michel Foucault, Paolo Freire, Benjamin Bloom, and Hannah Arendt, we propose a framework for assessing the use and ethics of AI in modern education contexts regarding human versus AI generated textual and multimodal content, and the broader political, social, and cultural implications. We conclude with applied examples of the framework and implications for future research and practice.

Authors: Öntaş Burak , Öner Jülide
Published: June 2024

This study focuses on alternative raw material sources to meet the demand for sustainable construction materials. Particularly, it is suggested that waste materials, such as animal by-products, could provide a solution for enhancing the mechanical properties and durability of asphalt concrete. The research aims to improve the physical and mechanical properties of asphalt concrete by utilizing bone powder obtained from Category 3 animal by-products through a hydrolysis procedure. Experiments conducted showed that the addition of 5% bone powder increased maximum stability when used in conjunction with different percentages of bitumen. Overall, some positive developments were observed in the physical and mechanical properties of asphalt concrete containing animal bone ash, possibly due to strengthening the bond between aggregate particles and bitumen material. This study highlights the potential of animal bone ash in improving the mechanical properties of asphalt concrete and recommends a 5% bone powder addition for optimum stability and durability. However, further research and field tests are needed to better understand the long-term effects of animal bone ash and its performance under different road conditions.
