Systemic Teacher Development for Enhancing Scientific Literacy Competency of Grade 6 Students Based on the PISA 2025 Framework Using the PCACK-4D Model: Diagnostic Research and Needs Assessment
Main Article Content
Abstract
This study aimed to: 1) diagnose critical learning management issues based on O-NET Science results for Grade 6 students over three academic years (2021–2023); 2) analyze critical test items using the Revised Bloom's Taxonomy and the PISA 2025 scientific literacy competency framework; and 3) conduct a needs assessment and propose guidelines for systemic teacher development using the PCACK-4D model. A mixed-methods design employing diagnostic research and needs assessment was utilized. The target group comprised 22 participants—11 school administrators and 11 Grade 6 science teachers—from 11 schools under a Quality Development Center, Chaiyaphum Primary Educational Service Area Office 1, selected through purposive sampling. Research instruments included the PROFILE program, a Revised Bloom's Taxonomy × PISA 2025 Matrix analysis form, and semi-structured interviews (IOC = 0.67–1.00). Data were analyzed using T-scores, percentages, content analysis, and data triangulation.
The findings revealed that: 1) All learning standards were classified at Level L1; the most critically recurring standards were SC 1.2, SC 2.1, and SC 2.3, each yielding the highest weighted score (10 points). 2) The most critical test item was Standard SC 2.1, Indicator P.4/1 (academic year 2021), with an average correct-response rate of only 6.33%—below chance-level performance—indicating severe deficiencies in the Evaluating cognitive level and the PISA 2025 competency of designing and evaluating scientific inquiry processes. 3) The qualitative needs assessment identified systemic gaps across four dimensions—administration, context, pedagogy, and knowledge—leading to the design of six Knowledge Stack innovations under the PCACK-4D model, serving as Organizational Memory to sustain knowledge transfer and systemic learning management despite personnel turnover.
