Recently, it has been developed in some other courses at UMMU Ternate such as at department of education of primary school teacher, department of public health, and especially at English department in Cross-Cultural Understanding course. Students’ awareness on local culture, national, domestic, and international first was not too easy to apply in the learning process, especially in individual interacting among students and teacher related to the material. To overcome these problems, it needs to implement the lesson study that includes 3 stages: planning (plan), implementation (do), and reflection (see). The goal of this lesson study in this course is to enhance students’ cultural awareness in-group discussion, improve the quality of teaching and learning, and build the pathways for ongoing improvement of instruction. This qualitative research was conducted in 4 cycles with its object was the fifth semester students consisting of 25 people. After reflection (see), the results found that students were actively participated and though insightfully to explore the ideas about the culture of what they met in their daily life through group discussion. Besides, teachers’ pathways in instruction had changed from being teacher center to be student center.
