This article was written to develop a teaching portfolio that helps lecturers maximize the benefits of blended learning, a combination of in-person and online learning, through the use of Team-Based Learning (TBL) teaching and learning approach. Studies show that TBL can provide opportunities in developing teamwork capabilities and enhancing active learning, which are effects that could remedy the weaknesses of implementing blended learning. A blended teaching portfolio was developed for an International Human Resource Management course that consisted of a course overview, graduate competency, a syllabus, course material resources, a teaching scenario, a reading assurance test, midterm/final exams, student assignments, assessment of learning outcomes, and a course quality improvement sheet. Each item was constructed based on the characteristics of the course. The portfolio was considered a valuable tool for lecturers to manage a blended-learning course that can help students in achieving higher scores and in motivating them to read course materials prior to class sessions.
