A Probability-Based Model for Course Completion Prediction in Online Asynchronous Learning
Authors: Kankanamge Pavindya Methsara 
Published: October 2024

The sheer scale of Massive Open Online Courses (MOOCs), presents a significant challenge in delivering personalized learning experiences and effective student support. With vast participation numbers, it becomes difficult for instructors to track individual progress, pinpoint specific areas where students struggle, and understand the underlying reasons for failure to complete the course. This lack of individualized attention can lead to disengagement and higher dropout rates. A probability-based analysis offers a solution by generating student-specific predictions about their likelihood of completion. This empowers educators to proactively identify those at risk, tailor interventions, optimize resource allocation, and potentially improve the overall learning experience within the MOOC environment. This study focuses on developing a robust predictive framework to accurately estimate the probability of students completing an introductory programming course offered on the Open Learning Platform of the University of Moratuwa, Sri Lanka. The approach began with a classification model to determine the likelihood of course completion. Building upon this, a regression model was developed to generate a specific probability percentage representing the chance of a student successfully completing the course within a designated time frame. Initial findings suggested that predictions from the classification model achieved the highest accuracy when students have completed approximately 42.8% of the course materials. It is anticipated that further refinements to the methodology will improve the reliability of the predictions. A crucial aspect of this research involves determining the optimal percentage of course progress needed to yield reliable probability predictions. This is investigated through systematic analysis and experimentations including incremental model testing. The dataset encompasses diverse demographic and educational variables, enabling the identification of influential factors affecting course completion. This study provides insights on developing personalized learning strategies, intervention tactics and academic planning within online asynchronous education.

Published: October 2024

Technology Enhanced Learning has become one of the key components of teaching and learning in the current environment and mainly because of Covid-19, hence the introduction of the Technology Enhanced Learning Programme. The Technology Enhanced Learning Student Assistants (TeL Assistants) programme supports students in the university with Blackboard (University choice of LMS). The programme was established in 2021 since there was a need to assist students in the use of Blackboard. With Covid, the university moved to strictly online and that became a challenge to the students. With most undergraduate students coming from disadvantaged high schools and backgrounds, there was a need for the programme. The TeL student assistants undergo training by the Teaching and Learning Consultants. The aim of this study was to evaluate how the TeL student Assistants supported the students of the University of Fort Hare on how to navigate Blackboard. This study examined the benefits of TeL student Assistant’s support in first-year students navigating their modules using Blackboard as an LMS. A purposive sample of undergraduate students that were trained by TeL student assistants submitted data through a qualitative survey in which they narratively conveyed their perspectives on support provided for Blackboard by the TeL Student Assistants. Data was analysed through coding, which were then assigned to themes and categories. The significant aspect of the TeL student assistants which enabled students to use Blackboard was the submission of assignments and tests, the facilitator’s knowledgeability and the patience students received from the TeL student assistants. The findings of the study directly benefit the university and higher education because they will provide information upon which we can take action to improve the support, retention, and throughput of students at the University of Fort Hare (UFH).

Published: October 2024

The tobacco crisis confronting low- and middle-income countries (LMICs) requires scale-up of effective tobacco control programs, such as Tobacco Free Teachers-Tobacco Free Society (TFT-TFS). We previously demonstrated the efficacy of TFT-TFS in increasing tobacco use cessation among teachers and schools’ adoption of tobacco control policies in Bihar, India. To scale TFT-TFS, we are now pioneering a smartphone-based mobile learning strategy to train principals (or their designees) in Madhya Pradesh to implement and monitor TFT-TFS in schools. Research underscores the transformative potential of mobile learning: a flexible, scalable, and cost-effective alternative to in-person training methods. Our study is a unique opportunity to test a training approach that could have implications for wider and more efficient delivery of other public health programs. The strategic use of gamification and digital storytelling enhances the TFT-TFS mobile training app. Gamification mechanics—including points, leaderboards, and digital badging—foster a dynamic learning environment to enhance learning outcomes. This approach propels continuous participant engagement toward understanding and implementation of TFT-TFS’s six monthly themes and four program components. The TFT-TFS smartphone training program weaves in elements of Indian culture, notably the symbolic use of colors and kites. The Indian kite festival celebrates communal harmony through healthy competition. Similarly, the app employs the idea of school kites, which are divided into six blank segments corresponding to the TFT-TFS monthly themes. Participants navigate each module, engaging with animated videos, digital assessments, and interactive activities. Upon a principal’s successful completion of each monthly theme’s program components, the school’s kite receives a new color, unlocking the subsequent theme. The TFT-TFS smartphone training showcases a unique interactive mobile learning application that integrates gamification and tests how to scale up an effective tobacco control program in schools in India and other LMICs. The TFT-TFS smartphone-based training app may also have relevance to other public health-related training efforts in resource-constrained areas.
WhatsApp Support for School Experience e-Portfolio Development: A Conversational Approach
Authors: Mqukuse Bongo , Nkonki Vuyisile , Tsipa-Booi Nobulali 
Published: October 2024

This paper reflects on the different ways of learning fostered by Whatsapp in the development of school experience e-Portfolios. Student teachers in one institution went through their school experience and practice teaching with an expectation to submit portfolios in an electronic format as evidence of their engagement with the theory and practice of teaching. WhatsApp interactions between student teachers, the school experience co-ordinator, and the practitioners in the Academic Development Centre, supporting the development of e-Portfolios, had to be relied on during the process of developing e-Portfolios. Informed by Laurillard's conversational framework on the six ways of learning, this study analysed the possibilities of WhatsApp support in the development of e-Portfolios by student teachers in one university. First and fourth-year education students on school experience provided qualitative data on the ways of learning that are best and least served by WhatsApp. Their accounts and evaluations of their interactions and support through WhatsApp were expressed narratively. Meaning units were extracted through content analysis and allotted to themes and categories suggested by the conversational framework. This study reports on the usefulness of the framework to evaluate WhatsApp support as well as the ways of learning that are most and least served by WhatsApp support on the development of e-Portfolios of evidence on practice teaching. Recommendations on the efficacious use of WhatsApp support for e-Portfolio development, the practices that would foster the realisation of all the six ways of learning, and enhancement of e-Portfolio development for the school experience are furnished. Suggestions are also proffered on further research about purposive use of WhatsApp and the conversational framework on e-Portfolio development.

Published: October 2024

The continuous progress of society requires all the actors to be dynamic and constantly updated, both in terms of monitoring as well as in the need to adapt. Regarding education, no matter how updated we are in relation to the contents, didactic strategies, and technological resources, we are still inevitably forced to adapt to new paradigms, leading us to reformulate traditional teaching methods. In this context, the contribution of e-learning platforms emerges, where teachers and students have at their disposal new means of empowering the teaching and learning process, since these platforms can be defined as a virtual teaching support environment. Currently, our students, in general, have many difficulties in problem-solving and mathematical reasoning, which often reflects in the performance of very simple tasks, with a growing disinterest towards Mathematics. It is also possible to argue that our students' "poor preparation" is a contributing factor in their failure (many did not attend Mathematics in Secondary Education and/or have not studied for several years, as is the case of those who entered through special contingents, as the “aged 23 and over”). In order to promote a distinct, alternative and supportive pathway that may help to solve this issue, a project on the Moodle learning management system (LMS) platform has been developed with the goal of assisting students in their study and the development of their skills in a way that is directly related to the curricular units (CU) in the scientific field of Mathematics, in an online learning environment. To increase students’ engagement into their learning process in a collaborative environment, a flipped model was employed into a Financial Mathematics/Financial Calculus Course (FCC). This paper's primary goal is to examine the effects of implementing the flipped classroom paradigm on students' performance, learning, and classroom instruction. The results from employing this approach have indicated a beneficial effect on the overall academic progress of students.
Grain refiner fabricated by spark plasma sintering for hypoeutectic Al–Si alloy cast and its refining ability

Published: October 2024

Abstract
Grain refiner fabricated by spark plasma sintering (SPS) for an as-cast hypoeutectic Al–Si alloy were proposed. The proposed grain refiner contains Al3Ti and Na flux particles in an Al-11 mass%Si alloy matrix. Through SPS, the grain refiner were obtained without any reaction between the Al3Ti particles, Na flux particles, and Al-11 mass%Si alloy matrix. Casting tests were conducted using the proposed grain refiners, and the refiners reduced the dendrite cell size and the dendrite arm spacing of the primary α-Al phase, as well as the lamellar spacing of the eutectic structure. The eutectic Si phase changed to a granular shape upon the refinement of the eutectic structure. Furthermore, the tensile strength and ductility of the as-cast Al-11 mass%Si alloy were drastically improved by adding the proposed grain refiner. This improvement was attributed to the refinement and granulation of the eutectic Si phase.
Electrostatic attraction and charge accumulation of poultry red mites (Dermanyssus gallinae) under high electric fields

Published: October 2024

Abstract
This study investigated the electrostatic properties and behavior of poultry red mites (Dermanyssus gallinae) under high-voltage electric fields. We evaluated mite mortality rates under various electrode gap distances and mite densities, quantified mite attraction to electrodes under different electric field strengths, and measured electrostatic charge accumulation on mites. The results showed that narrower electrode gaps and lower mite densities led to higher mortality rates. Mite attraction to electrodes increased significantly with the electric field strength, with over 85% of mites attaching to electrodes at field strengths ≥10 kV cm−1. The voltage rise time was found to negatively correlate with the mite attraction efficiency. Charge measurements revealed that mites accumulate electrostatic charge proportional to their number, with engorged mites exhibiting higher charges than their starved counterparts. These findings provide valuable insights into the electrical properties of D. gallinae and their response to electric fields, contributing to our understanding of mite behavior under electrostatic stimuli.
A comment on the Revised Diffusion Model for Conflict tasks (RDMC)
Authors: Janczyk Markus , Mackenzie Ian Grant , Koob Valentin 
Published: October 2024

AbstractIn conflict tasks, such as the Simon, Eriksen flanker, or Stroop task, a relevant and an irrelevant feature indicate the same or different responses in congruent and incongruent trials, respectively. The congruency effect refers to faster and less error-prone responses in congruent relative to incongruent trials. Distributional analyses reveal that the congruency effect in the Simon task becomes smaller with increasing RTs, reflected by a negative-going delta function. In contrast, for other tasks, the delta function is typically positive-going, meaning that congruency effects become larger with increasing RTs. The Diffusion Model for Conflict tasks (DMC; Ulrich et al., Cognitive Psychology,78, 148–174, 2015) accounts for this by explicitly modeling the information accumulated from the relevant and the irrelevant features and attributes negatively- versus positively-sloped delta functions to different peak times of a pulse-like activation resulting from the task-irrelevant feature. Because the underlying function implies negative drift rates, Lee and Sewell (Psychonomic Bulletin & Review,31(5), 1–31, 2024) recently questioned this assumption and suggested their Revised Diffusion Model for Conflict tasks (RDMC). We address three issues regarding RDMC compared to DMC: (1) The pulse-like function is not as implausible as Lee and Sewell suggest. (2) RDMC itself comes with a questionable assumption that different parameters are required for congruent and incongruent trials. (3) Moreover, we present data from a new parameter recovery study, suggesting that RDMC lacks acceptable recovery of several parameters (in particular compared to DMC). In this light, we discuss RDMC as not (yet) a revised version of DMC.

Published: October 2024

Film tidak hanya menjadi hiburan bagi masyarakat tetapi film juga banyak mengangkat dan menyajikan tentang isu-isu sosial yang berada dimasyarakat. Film menyampaikan realita sosial dan budaya pada masyarakat dalam kehidupan sehari-hari, terkadang dalam sebuah film juga terdapat kritik terkait isu sosial di sekitar masyarakat dan hal tersebut secara tidak langsung menambah pemahaman penonton tentang peristiwa yang terjadi dikehidupan masyarakat. Salah satu film yang mengangkat terkait isu sosial dan budaya adalah film Ngeri-Ngeri Sedap, karya Bene Dion Rajagukguk. Film ini mengangkat kehidupan keluarga Batak yang mengalami disrupsi, atau perubahan nilai nilai budaya. Penelitian ini mengunakan pendekatan kualitatif deskriptif, dan menggunakan analisis semiotika John Fiske untuk mengetahui representasi budaya Batak khususnya pada perubahan nilai budaya yang dilakukan oleh Domu, Gabe, dan Sahat menggunakan tiga tataran level, yaitu level realita, representasi, dan ideologi. Hasil benelitian ini juga dibagi menggunakan tiga tataran level, yang pertama pada level realita menunjukkan adanya 17 scene yang menunjukkan pergeseran nilai-nilai budaya, seperti perubahan dalam budaya pernikahan, perubahan aspirasi dalam karir, dan tidak lagi mengikuti budaya yang mengharuskan anak terakhir mengurus orang tuanya, pada level representasi adegan yang penulis teliti banyak menggunakan tekhnik pengambilan gambar medium close up untuk memberi kedalaman emosi serta mimik wajah dalam setiap adegan, agar dapat mendalami setiap adegan dalam film, serta tidak adanya musik untuk memberikan penekanan pada dialog, agar tampat lebih nyata, serta suara alam khususnya suara air atau sungai menunjukkan daerah asal suku Batak Toba, yang tinggal di pesisir danau Toba. Terakhir adalah level ideologi yang menemukan perubahan nilai-nilai budaya Batak ke arah modernisasi, yang mana Gabe, Domu, dan Sahat menganggap budaya tidak lagi sebagai sesuatu yang harus dilakukan, selagi apa yang mereka anggap masih dalam batas wajar, meskipun tidak sesuai adat, mereka akan lakukan, terlebih lagi Domu, Gabe, dan Sahat sudah sedari kecil merantau dan tidak tinggal di daerah asal mereka, tentu saja nilai-nilai budaya dan cara pandang mereka tentang budaya telah bergeser.

Kemajemukan masyarakat dengan keragamannya, meniscayakan terwujudnya situasi dimana elemen-elemen masyarakat bersikap toleran, bisa sama-sama menghormati serta sama-sama menghargai perbedaan satu sama lain dengan posisi yang sederajat. Bila tidak, hal ini dapat menyebabkan gesekan satu sama lain dan menyebabkan konflik dan disintegrasi. Sejauh ini, nalar kolektif masyarakat tentang nilai multikultural kebangsaan masih terkooprasi oleh logosentris dengan hegemonic yang syarat dengan prasangka, kecurigaan, kebencian, dan reduksi terhadap kelompok yang berada di luar darinya. Akibatnya, ikatan-ikatan sosial melalui kolektifitas dan kerjasama hanya berlaku di dalam kelompoknya sendiri, tidak berlaku bagi kelompok lain.Tujuan umum penelitian ini adalah tercapainya pokok permasalahan (1) Untuk Mengetahui nilai-nilai multikultural dalam Al-Qur’an (2) Untuk mengetahui pendidikan multikultural dalam Al-Qur’an. Penelitian ini menggunakan jenis kepustakaan dengan metode yang digunakan adalah metode analitis komparatif.
