Abstract

Students often have math anxiety which results in low learning outcomes. Giving story questions turned out to raise student?s difficulties in solving problems, including identif ying elements that are known, asked, andadequacy of elements, and making mathematical models of story problems. This indicates that the problemsolving ability of non-mathematics major students in basic mathematics courses is low. Lesson Study Learning based on character education can facilitate the acquisition of solutions to the above problems. The most important stages in lesson study are stages of reflection (see), in which the stages are stated all findings in learning are then given input in order to improve learning. This study uses the descriptive method with a qualitative approach. The activity carried out is to describe the reflection of basic mathematics learning as the final stage of the lesson study implementation. The research variable is in the form of a dependent variable, such as students' problem solving abilities and independent variables, namely student activity and creativity. It was obtained an average problem solving ability of 81.52. While the students? activeness with an average of 8 3.4 categories is very active and the average of students? creativity is 81.3 with a very good category. The character building for students, such as honesty, discipline, creativity, curiosity, enthusiasm, responsibility, tolerance, hard work, democratic, friendly / communicative, independent, religious, caring for the environment, and socially concerned. Hopefully, further research can be carried out to improve abilities understanding?s student concepts in basic mathematics subjects.Keywords: lesson study, reflection, basic mathematics

Abstract

The external turmoil that occurs today has a negative impact on all the structure and order of the domestic system. One of the recovery efforts is the implementation of mental revolution through character education. The character education can be applied to the affective aspect ofthe basic mathematics learning which will be integrated with basic mathematics material using character to be implemented. In addition, the colleges can be a place for student character development. This research was conducted at Muhammadiyah University of Semarang andSemarang State University. This research is a quantitative descriptive research using UCLA evaluation method. The data were collected by questionnaire method and interview. The results showed, 1) lecturers have little impact on the development of student character.2) program planning, given the integrated learning character education. 3) Program implementation, character education has never been introduced or used in the majority of learning. Indirectly, some character education indicators have been embedded in the students.However, most indicators are still not fully embedded, such as honesty, religious, caring for others, discipline, hard work, self-reliance, and responsibility. Thus, it is necessary to develop character values on basic mathematics learning applied to processes, techniques, andassessment instruments.Keywords: Character education, UCLA, basic

Abstract

Basic mathematics courses are one of the subjects taught in non-mathematics courses or majors where the majority of students tend to avoid math. Mathematical problem solving skills of non-math students tend to be low. Though problem-solving ability is the main reason to learn math. So it is necessary to improve learning with lesson study through the application of problem based learning with character education approach. This research uses qualitative approach with descriptive method of analysis. The conclusion of this study is the implementation of lesson study through the application of PBL learning with character education approach is in accordance with the stages of the lesson study, namely planning (plan), implementation (do), and reflection (see). These three stages can improve students' mathematical problem solving skills in basic mathematics courses. Need to improve the way of learning, learning methods, and the atmosphere of learning so that the ability of students more leverage. Keywords : problem solving, lesson study, basic mathematic
