| dc.description.abstract | Teaching and learning in Mathematics Education mostly expository method, which combines lectures, question and answer, discussion and assignments. However, these methods have weaknesses, for example students can’t combine concepts in one course to the other subjects. This is a problem that must be resolved by a team of lecturers teaching courses so the quality will increase. But in fact, the principle of collegiality among faculty has not grown optimally. Hence the need an approach which is able to create collegiality relationship is established, so the issue of students that result in improving the quality of learning outcomes will be resolved. Lesson study is a model of professional development of educators through collaborative learning and ongoing assessment to build a learning community. This study aimed to describe the improvement of the quality of mathematics learning that implemented by lesson study in the learning process. Implementing Lesson Study was conducted on subjects of algebra structure and calculus 2 on the even semester 2010/2011, calculus 3 and numerical methods on the odd semester 2011/2012. The results showed that there are an increase in grade point average on a Calculus 2 is 12.8%, 5% for algebraic structure, 12.4% for calculus 3, and 14.5% for numerical methods. It can be concluded that in the first year of Lesson Study in mathematics education study program to improve the learning quality. | en_US |
