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

Metode numerik merupakan salah satu metode yang mempunyai peran sangat strategis dalam matematika. Masalah yang sulit atau bahkan tidak mungkin diselesaikan secara analitis dapat diselesaikan dengan metode numerik. Berdasarkan observasi awal peneliti disimpulkan bahwa 1) mahasiswa cenderung menghafal dan bukan memahami metode numerik, 2) pembelajaran masih bersifat konvensional, 3) mahasiswa belum mengetahui secara mendalam aplikasi metode numerik dalam kehidupan, 4) pembelajaran belum memanfaatkan aplikasi teknologi. Hal ini menyebabkan mahasiswa pasif dan motivasi belajar juga turun yang mengakibatkan kemampuan pemecahan masalah masih rendah. Solusi untuk mengatasi permasalahan pada matakuliah Metode Numerik adalah dengan penerapan model pembelajaran IDEAL Problem Solving berbasis Maple. Penelitian ini bertujuan untuk mengetahui pengaruh implementasi model pembelajaran IDEAL Problem Solving berbasis Maple pada matakuliah Metode Numerik. Hasil penelitian menunjukkan bahwa terdapat pengaruh keaktifan dan motivasi terhadap kemampuan pemecahan masalah yang signifikan.

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
