IoT-based technology was considered to refer to all heterogeneous objects and devices through any networks, and Blended Learning (BL) is the educational approach to combine face-to-face (F2F) instruction with ICT instruction. In this COVID-19 pandemic, a model of BL with IoT-based maybe the best New Normal solution for all educational stakeholders. While Traditional F2F is forced to change by social distancing to prevent COVID-19. Many IoT-based "things" could be added in class to create and improve a smart learning environment while portable devices could be joined for the learning goals. This study divided BL into 4 characteristics; F2F, Selfpaced, Tele-D, and Ubiquitous, which were further categorized into 3 typical cases of learning environments, Digital, Embedded, and Side-by-side cases. Content analysis method was used to analyze and synthesize a model from related literatures, textbooks, research, articles and websites. A framework of this model has 2 roles of user interfaces (teacher and student) which link 6 modules and a set of databases and 2 types of contexts (classroom and personal).

<p class="0abstractCxSpFirst">In 2021, the COVID-19 pandemic is still not over. Thailand is the one that is facing the second wave of new coronavirus. Schools and universities were closed, and faculties need to mostly teach with Online pedagogy, including the graduate students' courses. This study proposes to focus on the Ubiquitous area of the Blended Learning model with IoT-based to solve a problem of graduate students and their advisors by the qualitative focus-group technique. The mobile application draft was synthesized and designed to track and monitor graduate students' research activities on smartphones by built-in sensors. They should stay active along while researching the advisor’s assignments on their smartphone. Non-active periods are implied when several behaviors are detected. Virtualize dashboards are processed to report the total active learning period of students for the advisor's evaluation.</p><p class="0abstractCxSpLast">Moreover, students can continually monitor their self-efficacy to improve the online learning process. Besides, this study proposes to confirm the model’s quality by twelve experts with the questionnaire. The results show average scores of Propriety, Utility, Feasibility, and Accuracy standard are 4.32, 4.41, 4.37, and 4.21, respectively. Therefore, the Blended Learning model's overall qualities with IoT-based smartphones are extremely high and proper to implement.</p>
