This research aimed to: 1) Investigate the effectiveness of digital teaching guidance provided by educational supervisors affiliated with the Northeastern Primary Education Area Office. 2) Develop a model for digital teaching guidance by educational supervisors under the Northeastern Primary Education Service Area Office. 3) Evaluate the feasibility and benefits of the proposed model. The research consisted of three phases: Phase 1: Investigating the effectiveness of digital teaching guidance by educational supervisors, based on relevant documents, research, and interviews with a purposively sampled group of 30 individuals demonstrating outstanding practices (Best Practice). Phase 2: Developing a model for digital teaching guidance by educational supervisors and evaluating the model's suitability through a seminar involving 7 experts, using the Connoisseurship approach. Phase 3: Evaluating the feasibility and benefits of the digital teaching guidance model by educational supervisors. The sample group comprised 50 educational supervisors affiliated with the Northeastern Primary Education Service Area Office, selected through multi-stage random sampling. Statistical analysis used in the study included mean, percentage, and standard deviation. The research findings revealed that: 1. Effective digital teaching guidance by educational supervisors consists of four key processes: 1) Analysis of context, 2) Development of teaching guidance plans, 3) Observation of teaching practices, and 4) Reflection on outcomes. Each process involved problem analysis, needs identification, collaborative planning, and the systematic use of digital tools and online social media aligned with the teaching guidance process. The effectiveness of teaching guidance was evaluated through the assessment of teachers' knowledge, understanding, and learning management abilities, collaboratively determined and facilitated through an online Professional Learning Community (PLC). 2. The developed model comprises five components: 1) Principles and concepts, 2) Objectives, 3) Core content of the model, including the four-step digital teaching guidance process, 4) Implementation guidelines, and 5) Success conditions. The model's suitability was assessed at the highest level. 3. In the feasibility and benefits assessment, the overall evaluation indicated the highest level of feasibility and benefits.
