Most HCI-related courses offered by the universities in Indonesia are delivered using conventional face-to-face methods. This paper describes the preliminary findings from the implementation of active learning instructional strategies in a blended undergraduate Human-Computer Interaction (HCI) unit offered by the Faculty of Computer Science, University of Indonesia. The study was conducted with one hundred and twenty-two students enrolled in the Computer Science and Information System programs. The face-to-face teaching and learning activities, i.e. lectures, project-based group activities, hands-on learning experiences, and assessment of this unit are supported by a Moodle-based learning management system named Student Centered e-Learning Environment (SCELE). The students were encouraged to explore the topics through social learning interaction in SCELE. Their knowledge and skills were further constructed through the face-to-face learning activities. Active learning instructional methods were applied throughout the unit to deepen their understanding and skills in Human-Computer Interaction. In this paper, we present qualitative data collected about the students' perceptions of their new learning experiences in this unit.
