    Multifaceted Instructional Design Strategies in Improving Generic Science Skills (GSS): A Review
    (Faculty of Humanities and Sciences, SLIIT, 2024-10-20) Agalya, V; Seneviratne, D. V. K. P.
    Sri Lanka’s Advanced Level Biology curriculum, known for its competitiveness, has been criticized for being overly theoretical and lacking essential Generic Science Skills (GSS), crucial for fostering scientific competence. This study aims to clarify the concept of GSS, identify its components, and determine suitable teaching methods, instructional design strategies, and assessment techniques to enhance students’ GSS proficiency. Adopting a deductive approach, a qualitative systematic review was conducted following the ENTREQ framework. Data were collected from four databases-Google Scholar, ERIC, World Wide Science, and Science.gov-between June and August 2024 using the keywords “Generic Science Skill” and “Science Generic Skill.” Of 773 articles retrieved, 60 met the inclusion criteria: published between 2010 and 2024, in English, with relevant keywords in the title. GSS are conceptually synthesized and defined as fundamental competencies that enable individuals to think critically and apply scientific knowledge in decision-making. Ten core components of GSS were identified: direct observation, indirect observation, awareness of magnitude, symbolic language, logical consistency, logical framework, logical inference, cause and effect, mathematical modelling, and abstraction. Effective teaching methods found in the literature include inquiry-based learning, ethnoscience approaches, and problem-based learning. Instructional design models such as ADDIE, SSCS, 4D, and Mini-Course Design were recognized as effective for developing GSS, while the PLOMP model was identified as an effective assessment framework for evaluating GSS proficiency.

    Towards Real-Time Market Intelligence: Event Detection and Latency Analysis in High Frequency Trading Dashboards
    (Faculty of Humanities and Sciences, SLIIT, 2024-10-18) de Silva, U; Perera, S; Liyanage, U.P; Erandi, H
    High Frequency Trading (HFT) relies on millisecond level decisions, where market responsiveness and system latency directly determine profitability. Traditional dashboards offer real-time visualizations but often fail to detect abrupt market shifts or quantify the delays in system reactions. This paper presents an AI-aided Market Pulse and Latency Panel that integrates candlestick pattern recognition, statistical change point analysis, and latency measurement into a unified trader-facing dashboard. The system identifies technical patterns, detects structural regime shifts, and quantifies latency. Experimental evaluations demonstrate that the panel captures both microstructural signals and broader regime changes while exposing critical latency bottlenecks, such as API-induced delays. By combining event detection with latency analytics, the panel advances dashboards beyond descriptive visualization, providing traders with actionable insights for strategy adjustment and infrastructural optimization.

    Human Primary Stem Cell Cultures as Screening Platforms for Botanical Preparations as Alternatives to Animal Models: Evaluating Cell Proliferation Stimulatory and Inhibitory Effects
    (Faculty of Humanities and Sciences, SLIIT, 2024-10-15) Udalamaththa, V; Ratnayake, P; Udagam, P
    Animals are widely used as human “models” in scientific research, yet primary human stem cell cultures provide an alternative under the 3R (Reduction, Replacement and Refinement) concept to reduce and replace animal models. This study investigated the cell stimulatory effects of selected botanical preparations on primary human stem cell cultures. In-house established primary human fibroblast (hFSC), mesenchymal (hMSC), and haematopoietic (hHSC) stem cells, derived from surgical waste, were characterized by immunophenotyping. The proliferation effects of Carica papaya leaf concentrate (MLCC), Vernonia/Mallotus (VMD), and Ficus benghalensis (FBD) distillates were assessed using the MTT assay. MLCC significantly stimulated proliferation in male and female hMSCs and hHSCs (p<0.05). FBD promoted proliferation in male hMSCs and hHSCs but inhibited female hMSCs. VMD inhibited both male and female hMSCs yet stimulated female hHSCs at 0.6%. Notably, VMD at selected concentrations exhibited approximately 1.5-fold higher cell stimulation than the positive control (p<0.05). These findings highlight effective botanical concentrations for cell proliferation, demonstrating the utility of primary human stem cell platforms as “models” in biomedical research. This approach aligns with the “replacement” principle of the 3R concept, promoting ethical and humanrelevant alternatives to animal testing.

    Assessment Literacy in Practice: A Study of Formative Writing Assessment Methods Among English Teachers in Wattala International Schools
    (Faculty of Humanities and Sciences, SLIIT, 2024-09-15) Hafsa, S.F; Rathnasena, U
    Research into the technicalities of Writing Assessment Literacy (WAL) is an expanding domain with many scholars stressing that its complex practical elements have not been fully developed in both pre- and in-service teachers due to oversights in teacher education and professional development. This study used survey data (n=20) and interviews (n=5) to investigate the practices of English language teachers related to the selection of formative writing assessments and the use of such assessment data from international schools in the Wattala Divisional Secretariat. The results complement existing findings that a majority of teachers mirror summative assessments in the practice of formative writing assessment, encounter challenges in the use and understanding of rubrics and feedback, and face limitations in the effective use of assessment results. The study concludes that specialized training in theory and practice related to WAL is needed to broaden the scope of classroom assessment methods used by international school teachers with focus on alternative assessment, transparent feedback practices, and purposeful collaboration between educators.

    A Blend of Arbitration and Mediation: Analysis of the Possibilities and Challenges in Utilising MedArb Practice in Sri Lanka
    (Sri Lanka Institute of Information Technology, 2024-12-31) Vithanage, P
    The ADR landscape is evolving at a rapid level across the world and one of the latest trends in such is transferring dispute resolution into Arb-Med-Arb and Med-Arb. Arbitration and Mediation are recognised as two favourable dispute resolution methods, especially in commercial dispute resolution. When considered in isolation, both mediation and arbitration have unique features. Despite a few substantive and procedural drawbacks in both methods, mediation, and arbitration have gained popularity recently. While transferring into a mixed approach of MedArb and Arb-Med-Arb is still in its infancy in the context of Sri Lanka, this paper examines the possibility of utilising MedArb practice within the existing landscape in the country. Arbitration practice in Sri Lanka has a long history and the Arbitration Act No. 11 of 1995 and its amendments suggested which are to be in force in the future lays the statutory framework for arbitration. Notably, the background for Mediation in Sri Lanka started with community mediation and now it has reached a significant milestone in commercial mediation as the enabling legislation for the Singapore Convention was enacted recently. This paper uses a doctrinal approach in dealing with primary resources as well as secondary resources when conducting the research. This paper uses an exploratory analytical method. It also includes a comparative study that examines the MedArb practice in Hong Kong as a progressive Common law jurisdiction. In its findings, the paper highlights that the MedArb practice is adaptable in Sri Lanka within the existing statutory framework and the institutional setup. However, it urges that the professionals and the commercial community pay attention to the points discussed in the recommendations for the successful functioning of the MedArb practice.
