The Proposal of Paper, ICSEI 2014 Yogyakarta. PROFESIONAL DEVELOPMENT OF TEACHER USING LESSON STUDY IN TEACHER EDUCATION Abstract The main objective of this research is to improve student teachers competencies at the Mathematics Education of Faculty of Teacher Training and Education Sriwijaya University through Lesson Study. The study focused on the improving of competencies pedagogical, professional, and social. In order to do so, development research was used. Research subject is student teachers at the 7th semester who follow the Statistic Method course. Three main steps of lesson study were conducted namely plan, do and see. Results showed that student teachers were able to improve their competencies such as: (1) the ability to discuss, among teachers and students, and between students and students; (2) Student problem solving skills through contextual statistics problem, and (3) the ability to investigate normality test. Keywords: Lesson Study, Professional Development, Teacher Education, Statistics Methods Target Audience: Researchers, policy makers, teachers and student teachers who interested in implementing innovation in this case lesson study in order to improve the performance of students of teachers education. THE PROPOSAL OF RESEARCH PAPER PROFESIONAL DEVELOPMENT OF TEACHER USING LESSON STUDY IN TEACHER EDUCATION Objectives Professional teachers and lecturers should have four competencies: pedagogical, professional, personal, and social. Teachers and lecturers should have the ability to manage the learning of students, the other hand teachers and lecturers are required to be able to prepare teaching materials, teaching in the classroom, and evaluate (Zulkardi & Ilma, 2006). One of the courses in the mathematics course is Statistical Methods which is an important subject, which is expected after following the course students are able to apply statistical material using ICT in this blog for the purposes of completion of under graduate thesis. During this learning process of Statistical Methods course, has not run well, it is seen from lecturer teach only one direction, where students just listen and take notes. Materials provided yet meaningful, so that students are less visible activities during the learning process takes place. Besides that lecturers course not collaborate in developing teaching materials and learning to apply them in so there is no cooperation. One of the issues of educational interest to be discussed is about Lesson Study, which emerged as an alternative to overcome the problem of learning practices that have been deemed less effective. Lesson study is a review of the implementation of learning activities undertaken by teachers. So, lesson study is not the method of teaching, although in the study of learning activities, teachers will definitely discuss teaching methods, media, and learning aids used in the learning process is a learning assessment activities are conducted by teachers. The role of teachers in the educational process required to always improve his ability as a dignified and professional personnel. Therefore, any improvement efforts being made to improve the quality of education. Various efforts have been made to improve the quality lecturers such as increased ability/mastery of a wide range of strategies or methods of learning and media. Advances in the field of information and communication technology in education many are using blogs as a medium of learning. The existence of the blog is currently expected to be used to its full potential as an alternative media delivery of knowledge, learning on-line media, as well as solutions to the problem of the lack of conventional teaching hours in the classroom (Sujinal, 2011). The purpose of this paper is to developed teaching materials using a media blog and using Lesson Study. This research aims to describe the efforts made in improving pedagogical, professional and social lecturer Mathematics Education Mathematics Education of Faculty of Teacher Training and Education Sriwijaya University through Lesson Study. - Perspective(s) or theoretical framework This paper mainly uses the following two theories: Lesson study is a cycle of activities in which teacher design, implement, and improve one or more research lessons and make positive changes in instructional practice and student learning (Stigler & Hiebert, 1999) Realistic Mathematics Education (RME) (Gravemeijer, 1994, 2010) is a domain-specific instructional theory, which offers guidelines for instruction that aims at supporting students in constructing, or reinventing mathematics in problem-centered interactive instruction. - Methods, techniques or modes of inquiry In this research the professional development of teachers to use lesson study with the step plan, do, and see. 1. Plan In the planning step, the lecturers who are members of Lesson Study collaborating to develop a syllabus that reflects the student-centered learning. Planning began with analyzing the needs and problems faced in learning, such as about: a description of the course, students activities, anticipate the lack of facilities and learning tools, so as to know the real range of conditions to be used for the sake of learning. Furthermore, together also look for a solution to solve all problems found. Conclusions from the analysis of the needs and problems of a part that must be considered in the preparation of the syllabus, so the syllabus into a plan that is really very mature, in which there could anticipate all the possibilities that will occur during the execution of the learning takes place, both in the early stages. 2. Implementation (Do) In the second step, there are two main activities, namely: (1) the implementation of learning activities undertaken by one of the professors who agreed or upon his own to practice syllabus that has been developed with, and (2) activities of the observation or observations made by members or Lesson Study other communities (read: professors and students who act as observers/observer). 3. Reflection (see) The third step is a very important step for further efforts to improve the learning process will depend on the sharpness of the sets of analyzes based on observations of the implementation of learning that have been implemented. Reflection activities carried out in the form of discussions which followed the participants Lesson Study led by the chairman of a course or other designated observer. Discussion begins delivering impressions of lecturer who have been practicing the learning, by submitting a comment or suggest general or special impression on the learning process is doing, for example, the perceived difficulties and problems in implementing the syllabus has been prepared. - Data sources or evidence Data were collected using observation (activities of students and teacher model) and documentation (student’s solution or contributions), field note and video-recording(classroom situation). These data will be presented during presentation in the conference. - Results and/or conclusions/points of view Results show that the student of teacher education can understand the statistics method and its application in the study by using Excel. At the time of learning in the classroom, teachers provide materials to address the issue through a blog www.blog.unsri.ac id/ratuilma. - Educational importance of this study The importance of this study can be used for improving the performance of teacher education especially in learning lesson materials using ICT. Furthermore, this study enriched and improved the students’ learning experiences. - Connection to the themes of the congress This paper is strongly related to the theme of ICSEI 2014 that is exploring and understanding contemporary approaches to teaching and learning. The topic is professional learning for initial teacher education. Here, the researcher collaborated with team (educators) in implementing the innovations (RME and Lesson Study) that are recommended by the policy makers in order to promote quality in mathematics education in Indonesia. Of course, during the discussion, comments and recommendations from audiences are needed to improve the quality of the professional development program. References Graveimeijer, K. (1994).
