1 LEXICAL IDENTITY AND DISCIPLINARY DIFFERENTIATION IN ENGLISH PROGRAM CURRICULA: A CORPUS-BASED KEYNESS ANALYSIS ACROSS 38 THAI RAJABHAT UNIVERSITIES

SAPOLACHET PRACHUMCHAI — 2026-08-30

Curriculum design in higher education has traditionally relied on expert judgment rather than systematic linguistic analysis, leaving the lexical coherence and disciplinary identity of course descriptions largely unexamined. This study addresses that gap through a macro level corpus analysis of English course descriptions drawn from 38 Rajabhat universities across Thailand, spanning three professional tracks, namely General English (GE), Business English (BE), and English Education (ED). A corpus of 177,065 words compiled from 4,353 course description files was analyzed using keyness statistics, specifically Log-Likelihood, Log Ratio, and Juilland's D, with the British National Corpus and the Leipzig General Written English corpus serving as reference corpora. The findings show that 95 percent of the top 20 keywords differed significantly across curriculum types (p < .001). The BE curriculum was grounded in commercial discourse, the ED curriculum in pedagogical and institutional language, and the GE curriculum in humanities and translation related vocabulary, reflecting distinct English for Specific Purposes (ESP) orientations across the three tracks. A subsequent MANOVA confirmed a multivariate difference with a large effect size for the word cluster comprising "principles," "educational," and "management" (Pillai's Trace = 0.175, p < .001). Taken together, these results characterize the lexical differentiation underlying English curriculum discourse and offer a corpus-based framework for curriculum evaluation that can be applied in comparable English as a Foreign Language (EFL) context.

2 GUIDELINES FOR PROMOTING PARTICIPATION IN AGRICULTURAL WATER MANAGEMENT OF WATER USER FARMERS IN THE THOTHONG CANAL IRRIGATION AND MAINTENANCE PROJECT, IRRIGATION OFFICE 4

SOMAIRI WACHIRASUNTHORKUL — 2026-08-30

This research aimed to study the conditions, problems, and guidelines for promoting agricultural water management participation of water user farmers in the Thothong Canal Irrigation and Maintenance Project, Irrigation Office 4. The Population consisted of 375 registered water user farmers, selected using Krejcie and Morgan's sample size table. Key informants were 16 experts. Research instruments included questionnaires and interviews. Data were analyzed using frequency distribution, percentage, mean, standard deviation, and content analysis.

The findings revealed that: The conditions of farmers' participation in water management included opinion-hearing meetings held every three months, with the primary channel for reporting canal damage and water demand needs being through water user group leaders. Overall problems with participation in agricultural water management were at a moderate level. When considered by dimension, the dimension with the highest level of problems was participation in evaluation. The item with the highest problem score was the lack of defined penalties for farmers who violated the agreed water use regulations. Guidelines for promoting participation in agricultural water management included: general farmers who are not water user group committee members should be encouraged to participate in receiving information more widely; monthly meetings should be arranged between irrigation officials and water user farmers; irrigation officials and farmers should jointly conduct weekly canal area inspections; all relevant parties must collectively brainstorm on increasing productivity and optimizing water management efficiency; and group committees and irrigation officials should jointly survey problems and obstacles in water management.

3 A MODEL OF TRANSFORMATIONAL ACADEMIC LEADERSHIP IN THE DIGITAL AGE FOR SCHOOL ADMINISTRATORS UNDER THE PRIMARY EDUCATIONAL SERVICE AREA OFFICES IN THE NORTHEASTERN REGION

DARUNEE BOONWISED — 2026-08-30

This study aimed to develop and evaluate a model of transformational academic leadership in the digital era for school administrators under the Primary Educational Service Area Offices in Northeastern Thailand. The study employed a two-phase mixed-methods design. Phase 1 involved model construction through literature synthesis and exploratory factor analysis (EFA), using data from 520 school administrators, together with a needs assessment based on a sample of 385 respondents and 22 experts. The research instrument was a rating-scale questionnaire. Data collection methods included focus group discussions and connoisseurship. Data were analyzed using mean, standard deviation, exploratory factor analysis, and the modified Priority Needs Index (PNI _modified). Phase 2 involved evaluating the model by 11 experts using an evaluation form. The statistics used in data analysis included mean and standard deviation.

The findings revealed that the developed model, termed the "DIGITAL Model," comprises seven components ranked by PNI modified value as follows: (1) Development, (2) Idealized Influence, (3) Growth (Individual), (4) Intellectual Stimulation, (5) Teamwork Academic Leadership, (6) Academic Collaboration, and (7) Leadership Vision. The model consists of five structural elements: principles, objectives, structure, implementation, and evaluation. The model evaluation results indicated that accuracy was rated at the highest level, while propriety, feasibility, and utility were all rated at a high level.

4 A MODEL OF DIGITAL LEADERSHIP FOR SCHOOL ADMINISTRATORS IN SCHOOLS UNDER PROVINCIAL ADMINISTRATIVE ORGANIZATIONS

APICHAT PONGPU — 2026-08-30

This study aimed to construct and evaluate a model of digital leadership for school administrators in schools under provincial administrative organizations in Thailand. A two-phase mixed-methods design was employed. In phase 1, the model was developed by synthesizing existing literature and assessing priority needs (PNI _modified ) from a sample of 191 respondents selected through multi-stage random sampling, along with 20 experts. The research instrument was a rating-scale questionnaire. Data were collected through focus group discussions and connoisseurship. Data were analyzed using the mean, standard deviation, and the PNI _modified index. In phase 2, the model was evaluated by 11 experts via evaluation forms. The statistics used included the mean and standard deviation.

The research findings were as follows: 1) The digital leadership model for school administrators in schools under Provincial Administrative Organizations in Thailand, named the VICTOR Model, comprised six digital leadership components, ranked according to their PNI _modified values as follows: Visionary Digital Leadership, Intelligent Digital Acuity, Comprehensive Digital Management, Two-way Digital Communication, Organizational Digital Culture, and Refining Digital Skills. The model comprised six additional structural elements: principles, objectives, structure, procedures, evaluation, and conditions for success. 2) The evaluation results revealed that accuracy and feasibility were rated at a high level, while propriety and utility were rated at the highest level.
