    CHAPTER 1

    INTRODUCTION

    A.Rationale and Background

    Lesson Study engages teachers in creative and collaborative work in developing

    and researching a lesson through a design-tryout-reflect-revise cycle until it reaches a

    form to which they believe would be exemplary to them and to other teachers. It assumes

    that by investigating the teaching and learning process in the context of designing and

    implementing a lesson, it could provide teachers with experiences that has the potential to

    deepen their context knowledge and their knowledge about how students learn concepts

    and skills, develop teachers skills in designing and facilitating lessons, and most

    importantly develop the skills, habit and confidence in investigating their own lessons.

    Studies show that the way to go to implementing effective and sustainable

    educational reform will be through an inquiry-type professional development program

    and while the teachers are in action. One of these professional development models that

    has proven effective in Japan and is now being implemented and widely used in many

    countries is Lesson Study. It is also one of the identified factors for Japans high

    achievement in Third International Mathematics and Science Study (TIMSS).

    Lesson study is a professional development process that Japanese teachers engaged

    in to systematically examine their practice. The core activity in lesson study is for teachers

    to collaboratively work on a small number of Study Lessons. These lessons are called

    study lessons because they are used to examine the teachers practice.

    Fernandez and Yoshida (2004:7) state, Lesson Study is a direct translation for the

    Japanese termjugyokenkyuwhich is composed of two words:jugyowich means lesson, and

    kenkyu, which means study or research. Lewis (2002: 1) defines, Lesson Study is a cycle in

    which teachers work together to consider their long-term goals for students, bring those

    goals to life in actual Research lessons and collaboratively observe, discuss, and refine

    the lessons.

    Besides, Lewis (2002: 1-2) describes, Lesson Study is a simple idea. If you want to

    improve instruction, what could be more obvious than collaborating with fellow teachers

    to plan, observe, and reflect on lessons? While it may be a simple idea, lesson study is a

    complex process, supported by collaborative goal-setting, careful data collection on

    student learning, and protocols that enable productive discussion of difficult issues.

    Lesson Study is a collaborative activity that involves a small team of teachers

    gaining a deeper understanding of how students learn. Teachers routinely share

    resources and ideas as they plan, design, teach, evaluate and refine lessons for a unit

    of work. Reports generated from the lesson study experience can be shared with

    other teachers interested in implementing a similar professional learning process.

    Lesson Study is a professional development process that a small group of

    teachers systematically examine their interaction in order to improve the effectiveness of

    the experiences that the teachers provide to their students. The team of teachers

    identifies a common goal (e.g. equitable student participation; establishing a supportive

    learning environment that respects student differences; maximizing student

    engagement) within or across a curriculum area or stage of learning. One teacher in the

    team teaches a lesson. The other teachers observe the lesson either in the classroom or

  • 8/10/2019 Final Report Group 4 Ls 2014 Ok

    7/32

    7 | P a g e

    from a video of the lesson, focusing on agreed aspects of the teaching and student

    learning. The lesson study team then meets to reflect on the lesson observations and to

    review, revise and reframe the lesson prior to the lesson being re-taught by another

    teacher. The lesson study team engages in cycles of planning, observing, reflecting,

    reviewing and re-teaching, each time focusing on a pedagogical and content focus.

    Lesson study teams can elect to invite an external colleague (consultant, academic

    partner, critical friend) to participate in any of the stages of the lesson study cycle.

    In Japan and other countries, Lesson Study has been chosen and implemented

    because of the lesson study can improve the quality of teaching and learning process as

    well as lesson in classroom. This is understandable because (1) lesson study is an effective

    way to improve teaching and learning process trough Development of a shared

    professional knowledge among lesson study group members that based on real teaching

    practice, (2) the basic idea of lesson is every student achieve his or her highest quality

    learning, (3) the objective of a lesson become a main focus of a classroom instruction, (4)

    based on the real experience in classroom, lesson study can be able to become Foundation

    of instructional Development, and (5) lesson study makes teachers role as instructional

    researchers.

    The cycle of instructional Development of lesson study has three basic components,

    such as Plan, Do, and See. Plan is related to the activity of planning and goal-setting.

    Teaching, observing, and revising the research lesson are covered in docomponent of the

    cycle. Seestep consists of observing, discussing, and reflecting the Research lesson.

    There are six basic steps as a guide in implementing lesson study. The steps are (1)

    Form a lesson study group, (2) Focus the lesson study, (3) Plan the Research lesson, (4)

  • 8/10/2019 Final Report Group 4 Ls 2014 Ok

    8/32

    8 | P a g e

    Teach and observe Research lesson, (5) Discuss and analyze the Research lesson, and (6)

    Reflect on Your Lesson Study and Plan the next step.

    In the course DevelopingLessonStudy in Mathematics Education for Secondary

    School Teachers, we have learned many things about lesson study. The following

    questions are posted: What is lesson study? How is lesson study implemented? This

    report covers the result of our Lesson Study implementation with SMP Negeri 8

    Yogyakartastudents on Friday, 22 August 2014, at 07.15 until 08.35

    B.The Goal of Lesson Study

    Before the Lesson Study implemention, we have to make our own goals as our

    baseline on how to make our own lessons effective and successful.Teamwork and

    cooperation are important factors in reaching our target goal.

    The following are our goals in the implementation of Lesson study.

    1. Improve teaching and learning process through shared professional knowledge

    among group members that based on real teaching practice.

    2. Empowering the learners to learn most after engaging them to some tasks or

    activities that they view as significant to them and that presents a real problem for

    them with enjoyment and full of fun to make them feel the enjoyment of doing the

    activities while enhancing in them an increased interest and a positive attitude

    towards Mathematics.

    3. Facilitate a problem solving lessons that would engage students to represent ideas

    mathematically, solve problems in different ways and reason out without being

    shown a solution first.

    C.Preparation for Lesson Implementation

    Our group consists of five teachers as follow:

    1. Mr. Saiful Ghozi, M.Pd from SMP Nasioanl KPS Balik papan, East Kalimantan2. Mr. Muhammad Atik Afwanudin, S.Pd SMPN 2 Salem, Central Java3. Mrs. Purwati, S.Pd, MM.Pd from SMPN 6 Purworejo, Central Java4. Mrs. Ririn Aprianita, S.Pd.Si from SMPN 1 Wonosari Gunung Kidul, DIY5. Mr. Buoy Sorphea, MA of E.S. from Beung Trobeck High School, Cambodia.

    After careful and mutual discussion among the group member, we reached our agreement

    on the topics and model teacher for school implementation. Mr Saiful Ghozi was agreed to

    be model teachers. The topic for our school implementation is Congruence of Triangles for

    Grade IX

    Designing the Lesson Plan

    Before the school implementation on Friday 21 August 2014, we conducted peer teaching

    on Thursday, 21 August 2014 at Conference Room. We presented our teaching scenarios

    and followed up by reflections.

    Pictures of our activities during the plan session are provided below.

    Figure 1. Group discussion focus on Lesson activities

    Feedback :

    Overall the teacher and learning processes run well in which most students were

    actively engaged. Students enthusiastically involved in group discussion and

    learning. Almost none of students off task nor confuse. The problem given by

    teacher is challenging; lead students to think seriously and learn math

    meaningfully.

    Suggestion : Teacher should allow students to conclude the lesson.

    After observing Mr. Sorphea we find that we have some negative points during peer

    teaching activities we should improve as the following :

    1. Set the time properly for teaching.

    2. To push the students to solve the problem.

    3. To make the conclusion better.

    4. Make available reflection in order to pave the way for the real activities next time.

    Based on the reflection we revised our lesson plan and activities. The picture of

    reflection activitie is bellow ;

    CHAPTER II

    IMPLEMENTATION

    The Lesson implementation was conducted at SMP Negeri 8 Yogyakarta on

    Fiday, 21 August 2014. The lesson start at 07.30 a.m until 08.40 a.m.The group members

    and facilitator served as observers during the Lesson implemention. After lesson

    implementation, we conducted reflections. The description of lesson implementation and

    reflection are provided below;

    The Opening

    Teacher entered the classroom and started the lesson by introducing himself and our

    team. And teacher checked students attendance

    Teacher informed the topics of todays lesson and learning objective

    Teacher showed a picture at the slide about real problem that related to triangle

    congruence and gave motivation to the students that the material of triangle

    congruence is very important in our daily life. The picture is bellow;

    Figure 4. Slide of actual problem related the topic.

    Main Activities

    Teacher divided students into 6 group, each group consist of 4 6 students.

    Teacher gave the name to each group with the name mathematiciants ( Al

    Khawarizmi, Phytagoras, Rene Descartes, Pascal, Euclid, Einstein) and gave number

    label to all of students.

    Teacher distributed a set of triangle models to each groups, which contains of ten

    triangle models with different size.

    Students discussed in their group to find out the pairs of congruent triangle among

    these ten models.

    The groups who has finished can present their discussion result, and responded by

    the other groups. Teacher provided guidance and facilitate for class discussion.

    Here the picture of facilitating group in their discussions.

    Figure 5. Teacher fasilitates group discussion.

    First presentation came from Al Khawarizmi group. They said that there are three

    pairs of congruent triangle, based on the equality of each angle.

  • 8/10/2019 Final Report Group 4 Ls 2014 Ok

    14/32

    14 | P a g e

    After that, Pythagoras group presented their discussion result. They had the same

    result, but their reason is beside its three angles are same, the congruent triangle

    must have same length of its three sides.The picture of presentation is bellow;

    Figure 6. Presentation of group Phythagoras.

    Teacher gave example to prove that if the triangles have the same angles, it cant be

    concluded that those triangles are congruent.

    Teacher stated the first property of triangle congruence is Side Side Side property

    (S S S).

    Teacher guided the students to find out the other properties by asking questions and

    demonstrating two models of triangle which are not congruent.

    By the guidance of teacher, students found out the other properties namely Side

    Angle Side (S A S). This conclusion is delivered by student number 13. Bellow

    the picture :

    Figure 7. Student 13 delivered the conclusion of S-A-S property.

    By the guidance of teacher, students found out the other properties namely Angle

    Side Angle (A S A). This conclusion is delivered by student number 30.

    The Closing

    Teacher facilitates students to make conclution about what already discussed was.

    Discussions was resulting 3 properties if triangle concruence : (S S S) ,

    ( S A S) , ( A S A).

    CHAPTER III

    GROUP REFLECTIONS AND DISCUSSIONS

    A.

    REFLECTION

    Here the reflections had been recorded from each member of group in reflection

    session.

    1. Mrs. Ririn Aprianita.

    Basicly the lesson was running well. Mr Ghozi has done his good job.

    At the beginning:

    - Teacher attracts students by showing a picture. It makes students pay

    attention on the materials.

    - Teacher stated learning objectives, so students know what is the purpose of

    todays lesson.

    -

    Teacher divides students into groups, but the members of each group

    - No clear instruction before students activity. Teacher gives instruction

    when the students are starting their work. So some students dont

    understand about their tasks.

    Main activity:

    -

    All students are active in their classroom.

    - Teacher lets students make their conclusion by their own sentences.

    - It takes too much time in presenting activity 1, so problem 2 and 3 wasnt

    explored well because of time limitation.

    Here the picture being reflection by Mrs. Ririn:

    21 | P a g e

    Figure 12. Reflection tatements from Mr. Atik.

    2. Mr Sorphea

    The sugestions are :

    - Should divide students into group earlier

    - Give cleaner instuction

    -

    Tell students to wear their badge altogether

    - Should give some more comprehension

    - Students can help and share their opinion

    - Students enjoy in learning on working

    - Teacher encourage students to show their abilities

    -

    Make good Conclusion

    3. Mr. Muhammad Atik Afwanudin

    Introduction

    - Teacher roll a student and ask them, who is not come in the class today

    - Students give attention to the teacher when He was given a problem

  • 8/10/2019 Final Report Group 4 Ls 2014 Ok

    22/32

    22 | P a g e

    Main activity

    - Students still have not confidence to say what they want, but the techer

    given motivation to all student

    - Most all of student is very interest about the subjejct matter, because the

    teacher use an actractif learning.

    - Some student in a group have not give attention when the other group

    presenting their discussion result

    -

    There is two student put the number label on their head

    Clossing

    - Students are not given an individual task to be done

    - Maybe the teacher forgot given a problem to be done as home work

    4. Mrs Purwati

    - Basicly the lesson study procces was runing well

    - The students are very actif in the lesson, they are glad to learn obot the

    proprties of triangle congruency

    - Theacher in lesson study has already done step by step

    5. Mr. Saiful Ghozi

    - All steps were already done as group 5 planned, but there are still loss many

    detail activities. Such as : check attendance list of students, give whorksheet

    paper that had been prepared before, give student homework, etc.

    - But for all activites teacher feels satisfied with the learning activities in

    classroom.

    B. DISCUSSIONS

    Lesson Study A noteworthy journey for learning

    Lesson study represents a willingness of teaching learning to improve the quality

    of our teaching and learning process, by accepting opinion/arguments by the other. With

    implementing lesson study, we know what our weakness of our teaching. It is very

    meaningful for us as an instrument of changing toward A professional teacher.

    The actual implementation of the lesson study was a great challenge for our group.

    We set our own goal to be achieved and carefully planned and collaborate every detail of

    our own insights and ideas for the Do Process to be undertaken successfully for the

    advantage or benefit of the learners to make them feel the enjoyment of doing the all

    activities while enhancing in them an increased interest and a positive attitude towards

    Mathematics.

    At first, the group are pressured and dont know where to begin with but on the

    process, after dividing the topics among ourselves, we begin to work out carefully every

  • 8/10/2019 Final Report Group 4 Ls 2014 Ok

    24/32

    24 | P a g e

    lesson and plan out activities suited for the topic to make it meaningful and full of

    substance.

    The group started to see the importance of collaboration, teamwork, cooperation,

    concern and moral support. We were there with each other in making a lesson plan,

    teaching materials, power point, and students worksheet and until the Do process was

    over. We exchanged ideas and we believe those are the things that made us all achieved

    the goal we planned for.

    Lesson Study A moment for celebration

    In general, every group member was able to carry out the lesson successfully. The

    time allotment was properly observed and all the activities given were very interesting

    and made the students respond positively. The teaching materials used were effectively

    used and help in easy learning process and the three basic component cycle of

    instructional development of lesson study such as Plan, Do, and See was well

    implemented.

    Lesson Study A way forward

    In general, every group member agrees that lesson study is a promising approach

    for teacher continuous development. Despite the obstacles that may arise in our own

    school cultures, we agreed that Lesson Study should be cultivate as part of our culture in

    teaching and learning processes.

    CHAPTER IV

    CONCLUSIONS AND RECOMMENDATIONS

    After implementing all steps in the Lesson Study processes, we come up to the following

    conclusions and recommendations:

    1. Lesson Study engages us teachers in creative and collaborative problem

    solving activity in designing a lesson that teachers mathematics through problem solving.

    This method is based on learners construction of their own knowledge; learners learn

    most when they are engage in tasks that they view as significant to them and that presents

    a real problem to them; and learning is a social activity whatever the objective or the goal

    of the learning is.

    2. As a result of all the activities undertaken, the most important achievement

    of the group or learned out of it is that the change in our perception about the role of

    Problem Solving in Mathematics. During the planning stage and meetings conducted by

    the group, expressed apprehensions that they may not be able to done it successfully and

    that work problem or problem solving is the most difficult type of skill and they

    thought there is no way a student can solve it by themselves without being shown sample

    problems and solutions first but they thought wrong and the topics assigned to each one

    of them challenged their own assumptions. Their impressions were all positive and

    realized that a carefully planned lesson will be implemented successfully and produced

    students who can solve problems by themselves with proper guidance from the teacher.

    They learned that problem solving can also be a means for learning Mathematics rather

    than simply a reason for learning it; and, that students are more capable in solving

    problem on their own than they previously thought.

  • 8/10/2019 Final Report Group 4 Ls 2014 Ok

    26/32

    26 | P a g e

    3. Admittedly, we find Lesson Study at first another burden to us but as the activity

    progresses, we eventually appreciated it. We learned a lot from each other and the post

    conference or reflections with discussions of observations and giving remarks and

    suggestions became a venue for us to deepen our understanding of Mathematics and how

    students understand it and affect the quality of their thinking. Goal-setting, the first step

    in the lesson study process was done successfully. The teachers among our group agreed

    that our goal which is to make students value mathematics by developing their thinking

    skills was somewhat achieved.

    4. Since most students paid attention in every learning activity wherein teacher givesa

    lot of effort from the planning stage to application itself, it is suggested that lesson study

    activities to be carried should be well-planned and carefully prepared for every learners

    benefit and improvement. The teacher as much as possible should prepare and use

    appropriate teaching aids and ICT to make students activity more fun and exciting and

    for easier understading of the lesson.The teacher should just always create joyful and

    comfortable atmophere during class activities to motivate every to students pay attention

    and actively participate and to make them feel the enjoyment of doing the activities while

    enhancing in them an increased interest and a positive attitude towards Mathematics.

    LESSON PLAN

    Theme :

    To determine the congruent triangles and show the reason.

    Tittle of the Lesson :What triangles are congruent?

    Objectives of the Lesson :

    Students are able to follow and solve the problems about congruent triangles

    accurately.

    Time allowance : 80 minutes

    Plan of todays lesson :Learning Activity Teacher facilitation

    Introduction:

    - Teacher gives a problem and shows pictures :

    Suppose in some yacht race, we must certify

    that all of the sails are in the same sizes.

    Without unrigging the triangular sails from

    their masts, how can we ensure that they are

    in the same sizes?

    - Teacher cuts a pieces of rectangular paper into

    two same parts (by its diagonal) to

    demonstrate the example of congruent

    triangles.

    - Teacher asks some questions to the students.

    Teacher shows two different triangles and

    asks Are they the same or not?

    - Preparing figure to display

    Students activities

    - Teacher divides students into 5 groups.

    - Teacher gives some models of different

    - Preparing some models of

    triangle.

    Learning Activity Teacher facilitation

    triangles to each group.

    - Students find which the congruent triangles

    are.- Teacher controls each group activities.

    - Teacher asks question Have you finished?

    - Students answer

    Students presentation

    - Teacher gets the leader of each group to show

    the congruent triangle, and asks question

    why do you say that they are congruent?

    - Students are expected to explain their reason

    using the properties of congruent triangles.

    - Giving reinforcement about

    the principle (property) of

    congruent triangles :

    S-S-S S-A-S A-S-A.

    Problem Solving

    - Teacher gives worksheets to all groups to find

    congruent triangles from the following figures.

    Starting from easy problem.

    Figure 1: shows an isosceles

    trapezium with its two

    diagonals.

    Students must have known

    about the properties of

    trapeziums diagonals because

    they have learned on previous

    grade. So they can find the

    congruent triangles on it.

    Figure 2 : shows a circle with

    some triangles on it. Using

    their understanding about

    radius and chord, so we hope

    that they are able to solve this

    problem.
