Multi-Tiered Scaffolding and Scaffold Fading in Teaching Chinese as a Second Language: Effects on Oral Proficiency and Pragmatic Adaptability

/in /by

While instructional scaffolding is widely recognized in Second Language Acquisition (SLA), its synchronous integration and the subsequent effects of scaffold fading in Teaching Chinese as a Second Language (TCSL) remain underexplored. This study proposes and empirically validates a multi-tiered scaffolding model—comprising linguistic, practice, and experiential scaffolds—tailored for TCSL oral instruction. A quasi-experimental, mixed-methods design was […]

The Role of Potassium Silicate in Quorum Quenching Against the Virulence of Ralstonia solanacearum, the Causal Agent of Bacterial Wilt in Tomato

/in /by

Bacterial wilt caused by Ralstonia solanacearum remains one of the most destructive constraints in tomato production worldwide. The pathogen’s virulence is tightly regulated by quorum sensing (QS), which controls exopolysaccharide (EPS) biosynthesis, extracellular enzyme secretion, and biofilm formation. Targeting QS through quorum quenching (QQ) represents a promising anti-virulence strategy without imposing the selective pressure associated […]

Preg-Robbing in Refractory Gold Ores: A Critical Review of Mineralogical Controls, Pretreatment Strategies and Flowsheet Selection

/in /by

Preg-robbing remains a major constraint in the processing of refractory gold ores, particularly those containing carbonaceous matter, fine clays, and iron-bearing phases capable of adsorbing dissolved gold during leaching. This review critically evaluates advances reported between 2020 and 2025, focusing on the mineralogical controls of preg-robbing, its interaction with gold dissolution chemistry, and the effectiveness […]

Relationship Between Knowledge Level About Scabies and Scabies Symptoms Among Students Living in a Sports School Dormitory in Kupang, Indonesia: A Cross-Sectional Study

/in /by

Background: Scabies is a neglected tropical disease with high transmission risk in crowded living environments such as dormitories. Knowledge is often assumed to play a protective role, but empirical findings remain inconsistent. Objective: To examine the association between the level of knowledge about scabies and the presence of scabies symptoms among students living in a […]

The Predictive Role of Language Proficiency and Non-Cognitive Skills on Mathematical Competence among Maritime Students

/in /by

Mathematical competence is a fundamental requirement in the maritime industry, as it supports essential functions such as navigation, vessel operations, safety management, and data-driven decision-making among maritime professionals. This study examined the predictive role of language proficiency and non-cognitive skills on the mathematical competence of maritime students at Capitol University in Cagayan de Oro City, […]

The Research Design on the Management of Students’ English Learning Assessment Activities at High Schools in Tien Giang Province, Vietnam

/in /by

This paper investigates the research design on the management of students’ English learning assessment activities at high schools in the approach of PDCA (Plan, Do, Check, Art). It employed Kumar’s (2011) eight-step format in designing the research process and manipulated Taro’s (1973) formula to calculate its sample size. The sampling for two groups of administrators, […]

Scrub Typhus in Sri Lanka: Assessing the Burden and Spatial Distribution Using National Surveillance Data, 2020–2024

/in /by

Background and aim: Scrub typhus is an acute zoonotic infection caused by Orientis tsutsugamushi and transmitted through the bite of infected chigger mites. It is increasingly recognized as a major cause of acute undifferentiated febrile illness across the Asia–Pacific region. In Sri Lanka, scrub typhus has re-emerged as an important public health concern, yet comprehensive […]

Enhancing EFL Academic Writing through E-Portfolios: An Assessment for Learning Approach in Higher Education

/in /by

This study examines the use of e-portfolios as an assessment for learning approach to improve academic writing in English as a foreign language and explores students’ perceptions of this method. The study involved 30 first-year university students in Vietnam. A mixed-methods design was used, including a writing pretest and posttest assessed across task achievement, organization, […]

Configuration of Long Bone Fractures in Canines – Clinical Study of 151 Cases

/in /by

Fractures in dogs can be categorised based on clinical information and radiographic appearance of the fracture. Fracture classification systems like AISF /AO serve as an integral role in elucidating fracture biomechanics, predicting associated soft tissue trauma, and formulating an optimal fixation plan. Based on  non-weight bearing lameness on affected limb, aberrant angulation of the limb […]
