The focus of this research is to study a learning process through Project-based Learning and to analyze learning achievement of an Urban Planning class group. The sample group used in this study consisted of 22 undergraduates who registered for an Urban Planning class during the second semester of the 2013 academic year. Statistical analysis tools employed were mean and standard deviation. A few evaluation and observation worksheets were also used to observe and evaluate the students. This research analyzed students’ learning achievement in each domain through an urban planning project assigned by instructors. The results show that students gained more of the body of knowledge and architectural skills via project-based learning.
