Development of a School Partnership Management Training Module to Improve the Managerial Capacity of Senior High School Principals in Sekadau Regency

Abstract

This study aimed to develop a valid, practical, and effective school partnership management training module to strengthen senior high school principals' managerial capacity in Sekadau Regency. It was motivated by low partnership management competence: all 21 principals were categorized as “Poor” or “Very Poor,” particularly in program implementation (45.2) and supervision and evaluation (42.8). This research and development design used a mixed-methods approach adapted from the five-stage ADDIE model: Analysis, Design, Development, Implementation, and Evaluation. Participants included five principals for interviews, seven for a focus group discussion, two expert validators, five principals for a limited trial, and ten for a broader trial. The module was evaluated using a four-point Likert-scale instrument. Quantitative data were analyzed using mean scores, N-Gain, and a paired-samples t-test; qualitative data were analyzed through the interactive model of Miles, Huberman, and Saldaña. The findings indicated that the module was valid, with feasibility scores of 82.3% from material experts, 79.5% from language experts, and 81.7% from instructional media experts, all “Very Feasible.” Its practicality score was 84.2% (“Very Practical”), with readability (88.0%) and ease of use (86.0%) as its strongest features. Effectiveness was demonstrated by an increase in the mean score from 48.7 (“Poor”) to 76.4 (“Good”), an N-Gain of 0.54 (“Moderate”), and a significant difference (t = 8.742, p < 0.001). The greatest improvement occurred in supervision and evaluation, followed by implementation, organizing, and planning. The module is suitable as a training guide for strengthening principals’ partnership management with families, businesses, and communities.
