Lesson Study Final Report Mathematics Lesson Plan Sixth Grade Comparing Polyhedrons Prepared by: Lisa Armstrong Jose E. Carrillo Margaret Kesler Connie Perez Amanda Sanchez April 25, 2007 Central Elementary School Santa Clara, New Mexico 1 Lesson Study Final Report Central Elementary School Santa Clara, NM Fourth and fifth grade teachers at Central Elementary School in Santa Clara, NM were introduced to Lesson Study through the TIA-RETA Program in the fall of 2003. In conjunction with NMSU and WNMU professional development was provided to this group of teachers integrating technology and the lesson study concepts. At that time the focus of the research lessons was science due to low achievement test scores. Central Elementary School was afforded the opportunity to take Lesson Study as a class, receiving three university credit hours, as well as technology equipment to use in the classroom. In the fall of 2004, lesson study became the school-wide professional development plan. Science continued to be the area of focus for the research lessons. Participation in lesson study increased because of the incentives that teachers received through the TIA-RETA Program and through the encouragement of the building administrator. The lesson study process was beginning to be realized by participants as a valuable teacher-led professional development process. For the following two school years, the subject area of the research lessons changed from science to math. The staff decided to continue with lesson study although the program was not fully funded. The technology incentives that the participants received in the past were no longer available. The intrinsic value of the lesson study process was appreciated by participants. It was realized that lesson study impacts teaching and learning. In October of 2006 Central Elementary School received information about a lesson study project through New Mexico State University. The building administrator and four teachers felt it was a great opportunity to receive professional development from an expert on lesson study, Dr. Akihiko Takahashi. The lesson study group goal was developed and emphasized during the development of the lesson. The goal was, “Students will actively construct, utilize, and communicate mathematical concepts.” During the lesson the students connected their prior knowledge to the new knowledge presented. They utilized this new information to solve problems and use mathematical concepts. The students also communicated orally and in written form their knowledge of polyhedrons and their attributes. The following is a synopsis of the process of the research lesson project. 2 Central Elementary Lesson Study Group Activities 2006-2007 October 2006-April 2007; regular meetings and public research lessons 1st Lesson Study Conference, October 27-28, 2006, 8:30-3:30 at NMSU, Las Cruces, NM 1st Meeting, October 30, 2006, 2:00-3:00 2nd Meeting, November 13, 2006, 2:00-3:00 3rd Meeting, November 14, 2006, 2:00-3:00 2nd Lesson Study Conference, November 17-18, 2006, 8:30-3:30 at NMSU, Las Cruces, NM 4th Meeting, November 20, 2006, 2:00-3:00 5th Meeting, November 29, 2006, 2:00-3:00 6th Meeting, December 11, 2006, 2:00-3:00 7th Meeting, December 21, 2006, 2:00-3:00 8th Meeting, January 8, 2007, 2:00-3:00 9th Meeting, January 9, 2007, 2:00-3:00 10th Meeting, January 11, 2007, 8:00-3:30 11th Meeting, January 12, 2007, 8:00-11:30 12th Meeting, January 16, 2007, 2:00-3:00 13th Meeting, January 17, 2007, 2:00-3:00 1st and 2nd Public Lessons and Debriefings, January 18, 2007, Las Cruces High School, Vista Middle School, Las Cruces, NM 8:30-3:30 14th Meeting, January 23, 2007, 2:00-3:00 15th Meeting, January 30, 2007, 2:00-3:00 Research Lesson and Debriefing, February 1, 2007, Central Elementary School 16th Meeting, April 13, 2007, 2:00-3:00 17th Meeting, April 16, 2007, 2:00-3:00 18th Meeting, April 18, 2007, 8:00-11:30 19th Meeting, April 19, 2007, 3:00-5:00 20th Meeting, April 20, 2007, 12:00-3:30 21th Meeting, April 23, 2007, 2:00-4:00 3 6th Grade Public Research Lesson on February 1, 2007, At Central Elementary School Mathematics Lesson Plan for Sixth Grade For the Lesson on Friday, January 19, 2007 At Central Elementary School, Santa Clara, New Mexico Lesson Study Group: Lisa Armstrong, Jose Carrillo, Margaret Kesler, Connie Perez, Amanda Sanchez 1.

(Algebra) Create, explain, and use mathematical models such as: o three-dimensional geometric models o graphs, tables, and charts to interpret and analyze data 4 4. Instruction of the Lesson New Mexico sixth grade students are expected to make generalizations based on observed patterns and relationships. They should be able to communicate these mathematical generalizations verbally and in writing. After investigation of geometric figures, students will conceptually understand proportional relationships and develop a formula such as E=F + V – 2, where E=the number of edges of a polyhedron, F=the number of faces of a polyhedron, and V=the number of vertices of a polyhedron. Prior to the research lesson, students have been introduced to and explored basic geometric concepts such as the study of lines, angles, and polygons; they have measured angles, and constructed congruent line segments and angles. In further exploration the students identified line and rotational symmetry. They also identified solid figures; named and counted faces, edges, and vertices of prisms and pyramids; and modeled prisms and cylinders from nets. If students comprehend the numerical relationship between the faces, edges, and vertices of polyhedrons and their algebraic connections, they can incorporate them to find a formula such as E=F + V – 2. A lesson from Harcourt Brace Math Advantage, Faces, Edges, and Vertices Algebra Connection, was chosen and revised. The lesson was extended to help students realize the relationships between the faces, edges, and vertices of polyhedrons. Students will use models of polyhedrons previously built to explore the physical attributes of the solid figures. They will develop a method of communication to present their observations. 5. Lesson Procedure Learning Activities Teacher’s Questions and Expected Students’ Responses Teacher’s Support Points of Evaluation 1. Introduction We explored polygons and polyhedrons, we’ve built models of polyhedrons, and we’ve compared and classified pictures of polyhedrons. Now we will compare our models of polyhedrons and your group will present information about them. Use the available materials to visually present your findings to the class. Ask the question: “What do we need to know to compare the polyhedrons?” Review prior knowledge; pose the problem to the class in written format on the overhead projector. Do the students know the vocabulary? Can the students apply their knowledge to describe polyhedrons? Provide examples of Can students describe polyhedrons (see appendix). attributes of polyhedrons? 5 Now you will compare the polyhedrons and use the available materials to record Write students’ responses on the board. your groups’ findings. Students will present their findings. Are students discussing and recording their observations? Are they working collaboratively? Provide the materials for the Are students appropriately students to use during this using vocabulary in portion of the lesson. context? Call students to the front of the class one group at a time. 2. Posing Problem Is there a way to combine our information about the presented polyhedrons? Students’ anticipated responses: Organize information according to polyhedron attributes such as number of edges, faces, and vertices Derive the formula for the relationship between the number of edges, faces, and vertices of any polyhedron, E=F + V – 2. If students cannot graphically organize their results according to attributes, recall prior examples of graphic organizers. Do students recall methods of presenting information? 6 4. Summing up a. Using the students’ representations of polyhedron comparisons review what students learned through their explorations. Ask open ended questions to keep the discussion going. Can students explain and represent their comparison of polyhedrons? b. Ask students to write a summary explaining the relationship between polyhedrons. Ask the question “Is there a shorter way to express this relationship?” Do the students use variables to represent an algebraic expression? “When letters are used to represent numbers, what is it called?” Do students appropriately use variables in their summaries? 6. Evaluation a. As a small group were the students able to organize and present their comparisons of polyhedrons? b. As a whole group were students able to compile information and explain the relationship between polyhedrons? c. Independently were students able to explain their reasoning in written form? 7 Post Discussion for Research Lesson-Comparing Polyhedrons Central Elementary School Group Participants: Lisa Armstrong, Jose Carrillo, Margaret Kesler, Connie Perez, Amanda Sanchez Guest Observers: Daena Davis, Sonia Marrujo, Betsy Montes Lisa Armstrong: The students understood faces, edges, and vertices of polyhedrons. They discussed this but didn’t make the connection between them. There was a lot of thinking, they used good organizational skills, but once they had to present their findings they weren’t able to communicate their thinking because they were shy and learning stops. They’re thinking it, but we didn’t know what they were thinking. Daena Davis: Do you think that if they had stayed in their work areas they may have been more at ease, rather than being at the front of the room. I find that students are more comfortable presenting from where they are in the room. Amanda Sanchez: Also maybe giving each group only one shape to discuss and present on would help them to compare with other groups and have more discussion. Connie Perez: I think a lot of learning took place in working with all of the shapes. If you only focus on one then you can’t look at relationships. Amanda Sanchez: The goal was the numbers part – in finding the relationship between them. Betsy Montes: The students had a lot of prior knowledge. Were the students aware of what the goal was. The goal wasn’t met. Questioning while in their groups would also stimulate more thought. Did kids know questions that were going to be asked? If they had known what was expected, then they would have been ready. They could’ve written some responses. Margaret Kesler: In one of our lesson study sessions in Las Cruces/NMSU we talked about not asking leading questions. If you ask leading questions their creativity could be stifled and limit their discoveries. We kept that in the back of our minds when planning the lesson however if we had asked questions during the presentations to stimulate their thinking without being leading, it could’ve helped. For example, questions like “What was the discussion in your group?”, “What was brought up?”, “What did you not agree on?” Amanda Sanchez- Perhaps a focus question that they will answer during their presentations, maybe open-ended questions? Connie Perez-We had considered some questions during planning but decided they were leading and would tell them how to think. 8 Betsy Montes- Did you ask questions while they were in groups? Lisa Armstrong: I walked around more as a facilitator. Margaret Kesler: Maybe specific questions could have been asked to stimulate their thoughts during the presentation of their findings. Sonia Marrujo: Was your grouping of the students random? Some wee doing some of the work or most of the work and others were not as active in the activity. Lisa Armstrong: For the most part they chose their own groups. Betsy Montes- They were interacting, they were learning. Mr. Carrillo: I observed that one group, Jose, Brittney, and Zita rotated the tasks. Each one was looking at the shapes, one writing, one facilitating, one cutting-that assured that they were understanding the process. They all had an equal opportunity to share their work. There were other groups that each student only had one task. Betsy Montes: I wondered if roles were assigned. Connie Perez: One group continued to work during the others’ presentations, they all had different ideas about how to present the information on their board. Amanda Sanchez: They were trying to draw them when they saw everyone was using the pictures, and they were almost done. Then they started to use the pictures and they finished really fast. Margaret: Drawing them out might have helped some students. They really got a feel for the shapes and the attributes of them. Amanda: That is why I think each group having one shape to focus on may have been good. Connie Perez: It was nice that you used 3-D objects. I noticed that when one student was using the picture of the shape he needed to recount. Amanda: I think having the different types of manipulatives, they all chose something different, they all had enough materials to work with. Jose Carrillo: As far as evidence of student learning: one of the students was asking probing questions. She kept involving other members of the group but it was interesting that she didn’t take what she was doing at face value but asked the others in her group. She would engage them “Do you think?” “Do you think?” … As far as the different groups, most of them would go back and ask questions and check their work. 9 Connie: I think in the area of algebra, and considering the development of the students that perhaps the goal – finding the algebraic equation was not appropriate. Finding the pattern between the numbers would have been more appropriate at this time. Amanda: According to the standards and benchmarks students should have been able to come up with an equation. Students should already be finding the algebra part of it. They have to come up with their own formulas from a problem. They did get a lot of those types of problems on the practice tests. They had to come up with an equation from the information given. Daena: Have the students been exposed to formulas? Lisa: A little bit. Betsy: I noticed some used variables. Have you used variables? Lisa: Yes, in that F=faces E=edges V=vertices before the lesson. Connie: Yes, using the variables in that way. In actually using the variables in equations, I think the first step would be in finding the pattern in looking at all the polyhedrons and move from there. Daena: You could have given them only one of them but some of the kids can’t see the pattern in one, but need to compare them to other shapes to see what is going on between them. Amanda: But, if one group focused on one and they see the numbers, then when they presented it, presented their shape, then they would get the rest of them and as a class they could have come up with relationship between all of them. Lisa: I see what you are saying and what Connie is saying. The relationship between the numbers is the pattern. If they had time and could look through the numbers, they could see the pattern. Working with the variables then they could have probably come up with the equation. Daena: In one group you could see the formula the way their chart was set up. I think if they would have had time to focus on the chart they might have been able to come up with it. Amanda: I was thinking if they focused on one shape and they focused on the numbers part and they present the numbers part, the whole class is going to label it as a class. Once all the numbers are there then we could say something and they could maybe see the relationship. I think because they had so much information of geometry they focused more on the geometry part and not the algebra part. 10 Connie: Initially because of the lesson study groups within our school geometry was a strand, and so that it would meet with the algebra component with the NMSU group, we tried to tie the two together, but initially the focus was geometry. That’s why thinking all this algebra at this point was still asking too much. They were still working on many geometry concepts, the students did not realize the algebra concepts we had intended. The students really never got to look at the posters and compare them. They only saw them briefly. That would be the next step and that in itself would be another lesson in finding the Aha in patterns and relationships. It was a valuable lesson. They needed to have this lesson and work in their groups with all of the information and then do as Amanda said and take each piece and compare them. First finding the relationship and THEN finding the equation. It was expecting too much to move from the geometry concepts to the algebraic formula in one lesson. Sonia: Yea it was too much. Daena: You need to take baby steps. Mr. Carrillo: Any other comments Connie: It was fun, and you could feel the energy and the kids talking and excited about their work. Betsy: In groups there was a lot of interaction. You see more evidence of learning when students work in groups There was a lot of learning going on Connie: When they applied their knowledge in their groups today it was fun to watch Margaret: Each group developed their own system. I know we had said that some took over in their groups, but all students were involved somehow. Many of them checked each other. It seemed that Oliver had done all of the work, but in watching the video today I noticed that Nicholas really checked his answers. Lisa: I thought it was interesting the way they isolated the apex from the vertices. We had never said the apex is not a vertex. Mr. Carrillo: Our goal wasn’t met. What do we need to do to get there? Betsy: It was a great assessment of their prior knowledge – now they’re ready to go to the next step to reach the goal. The lesson should continue into further lessons. Ideas Each group focus on at least two shapes, manipulating the numbers in different ways. They are asked to compare the numbers. Groups will then discuss and compare their findings with the entire class. 11 The class will then compare the findings from each small group to find patterns/relationships. Questions are asked to keep students thinking. (What will the questions be?) Outcomes In reviewing the goals and expectations of the lesson, three out of the four goals were met. Goals that were met: a. To Identify solid figures b. To name and count the faces, edges, and vertices of prisms and pyramids c. To learn how different views of a solid figure compare Goals that were not met: d. To compare and contrast polyhedrons and explain the relationships The above goal was not met in this particular session, however with the right questioning in other lessons we may be successful in guiding students to this discovery. 12 Connie Perez Reflection Lesson Study NMSU I learned of lesson study three years ago when my principal invited each teacher at our school to become participants in a class at WNMU. The class was designed to help teachers enhance instruction through the use of the Lesson Study concept integrated with technology. Tuition was funded with grant money provided by TIA-RITA. The grant also provided incentives for teachers to assist them in increasing their use of technology in the classroom. I had no knowledge of lesson study but I accepted the invitation because of the technology component. Technology is not one of my strengths and I considered this an excellent opportunity to improve in this area. However as I became familiar with the lesson study concept, my focus changed and each component of the class became of equal value to me. During this first year, I discovered that lesson study is a paradigm of instruction in which the students are active, responsible learners and the teacher is a facilitator of their learning. This method makes teaching a collaborative process and makes learning fun, exciting, and involved. Concepts are explored, taught, and learned comprehensively. Instruction is qualitative rather than quantitative. If this method of instruction was the norm, I believe that our students would be more prepared for the standardized test which requires them to explain their learning. After this first year, I was eager to continue learning about the lesson study model to help me improve my classroom instruction. Over the next two years, the administrator and teaching staff at my school have continued the lesson study process in spite of the decrease in funding. Because of this decrease, my building administrator sought out other means of financing. As a result of this search, he learned of the program at NMSU and invited the lesson study facilitators at Central Elementary School to take part in this program. My colleagues and I thought we were attending a two day workshop presented by Dr. Takahashi. We were excited to have an expert be the facilitator. However, as we listened to opening statements, we soon realized that we would be involved in another lesson study process which was to include middle and high school teachers and students and would run over the course of several months. Initially, I was apprehensive and felt somewhat intimidated because I teach primary math concepts to young children and have not had the opportunity to instruct students at a higher mathematical level. However, after participating in learning activities with Dr. Takahashi as our facilitator, I now recognize the connection of what I teach to what is taught at higher levels. As I observed the students during the lessons at Las Cruces High School and Vista Middle School, I realized these students are no different than the young children I teach. I noticed that the students were at different levels of understanding and assumed different roles as they participated in the small group activity. The high school students were in groups but several of the groups did not work as a group and seemed to struggle with the task. I observed that the majority of middle school students in the small groups benefited from the hands-on activity based instruction as the teacher guided and facilitated their learning. It was exciting to watch as the students made mathematical discoveries. The students appeared to enjoy and benefit from the lesson. I gained insight 13 into the lessons during each de-briefing session. Having Dr. Takahashi and Dr. Tad share their expertise and views about the strengths and weaknesses of the lessons was helpful. Lesson study has been a worthwhile process. It has assisted me in improving how I appraise student learning. It has also made me more cognizant of the type of questions I ask my students. Lesson study has helped me to make better observations as my students are engaged in learning activities. I am grateful that I was given the opportunity to participate in the NMSU lesson study group. 14 Margaret Kesler Reflections on Lesson Study Learning about the lesson study process and being involved in lesson study groups has helped me to seek associations between classroom lessons and student learning. When planning a lesson I think about how the students in my class will be impacted and what the results will be. I attribute this deeper thinking of student learning to the involvement in lesson study: the valuable time spent with other teachers, the opportunity to observe interactions in the classroom, and the in depth discussions that bring about many ideas and questions. I feel fortunate to work in a school that has supported the lesson study practice for four years. This has given many of us the opportunity to grow in our experience with lesson study and see the value of it. When lesson study was introduced to our small group of teachers, I remember thinking that it was an ideal way to plan lessons consisting of everyone’s best ideas; however I did not see it as a venture that would last due to the time that is required for an effective process. Many times programs and new ideas are short lived and fade quickly. The lesson study process at Central Elementary has been supported and encouraged by our building administrator and therefore our lesson study groups have continued, have grown, and it has become a school-wide practice. I have had various opportunities to gain knowledge about lesson study. These opportunities include: attending classes at WNMU where lesson study and technology have been the focus, serving as one of the facilitators of lesson study groups at our school – in both a primary group (pre-K – 2nd) and intermediate group (3rd – 5th grade), and being part of the Lesson Study Project at NMSU. The classes at WNMU provided the time to work in our groups and improve the lesson study process. Serving as facilitator to groups within our school has given me the opportunity to help plan, observe and discuss many lessons, ranging from grades prekindergarten through 6th grades. Being a part of so many different grade level lessons has given me great insight to my own teaching – what my own students should know and where I need to guide them in their learning. During this school year our staff has not had any school wide professional development to expand our lesson study program at Central Elementary, therefore a few of us being a part of the NMSU Lesson Study Project has helped us to improve our practices. In attending the meetings and discussing all of the components of lesson study and the importance of each, realized that the observation piece in each of our groups needed to be addressed. Observing other groups’ lessons and their debriefing process was very enlightening. It has also been helpful to have knowledgeable experts in the area of lesson study to share their thoughts and experience with us. We were able to share what we learned with our own lesson study groups. Our public lesson was unfortunately cancelled do to inclement weather. I think the insight from outside experts would have benefited our teams. I believe that we have made gains in our practices, but would benefit from more ideas on the observation and debriefing portions of the process. 15 Lesson Study Reflection Lisa Armstrong I feel that I have grown as a professional through my experiences in lesson study. I have gone from knowing nothing about the lesson study process four years ago to being a facilitator for lesson study groups in my school. I have gained much professional knowledge in the lesson study process through personnel from WNMU, and in 20062007 through NMSU and Akihiko Takahashi. As a novice lesson study participant in 2003, I was given the opportunity to attend a lesson study overview workshop given by experienced lesson study participants from the Las Cruces School District. The workshop was moderated by Dr. Karin Wiburg of NMSU. I thought that the presenters were very enthusiastic in sharing their experiences about lesson study, and I left the workshop very confused about the process but with the desire to learn more. As part of the fourth and fifth grade lesson study team at my school, we began our lesson study process by identifying the academic needs of the students in our classes. We did this by interpreting standardized test scores to determine in which subject area there was a need for further teaching and learning. We decided to study a lesson designed for fifth grade students about chemical reactions called “Burnt Sugar.” This first research lesson was difficult because our lesson study group was inexperienced, having never participated in this kind of professional development before. With the help of our facilitator and some WNMU faculty members, we completed our first lesson study and gained much insight into the process. During our participation in lesson study, my school has undergone many changes. We have gone from having only a few participants to every teacher being involved in lesson study. We have had to overcome obstacles such as scheduling planning sessions, research lessons, and debriefings; and finding enough substitutes for every participant. Our facilitation of groups has changed from university faculty to in-house facilitators. I have been one of the lesson study facilitators at my school for two years. In that time I have learned much about group dynamics. I have learned that the teachers at our school work well together, share ideas, and collaborate to develop lessons. Because we were given an opportunity to work together through lesson study, teachers feel more a part of a family. I have realized that even though I have participated in the lesson study process for four years, I have much to learn. This year my participation in the NMSU Lesson Study group has proven to be invaluable. It has given me additional background knowledge I needed as a professional who is still learning through the lesson study process. Being an observer in public lessons has given me a great opportunity to learn about observation and debriefing in lesson study. The public lessons afforded the time to think about the mathematical concepts that were involved in each of the lessons. Observing the students and examining their responses is a benefit of being at a public lesson. Observing lessons at different grade levels is allowed me to take a brief look at what skills my students at the elementary level will need in the future. Through my experiences in lesson study, I feel that I have become a teacher who self-analyzes her teaching. My teaching has become more purposeful because I think about my lessons in an in-depth manner. I purposefully pose questions to students so they 16 think more critically about their responses. I believe very much in the lesson study method of teacher-led professional development and plan to continue to learn as much as possible about the process. I plan to continue my participation in lesson study in future years as a teaching professional. 17 Individual Lesson Study Reflection Amanda Sanchez I have been participating in lesson study for three years and have used it to enhance my teaching style. The first year of lesson study I was a student teacher mentored by Mrs. Virginia Rodriguez. She suggested that I join the program because it would be a vital tool in helping to assess lessons taught. I was excited, to be able to learn from all of the experienced teachers in the group. During the planning process the group improved the previous lesson taught and included more hands on activities for the students. The lesson was in science and included all the human organ systems. The lesson was led by Mrs. Rodriguez and included the other teachers involved. Each teacher was in charge of mini-lessons taught in small groups of four students. Each lesson focused on one of the organ system and was taught by with game situations. After all the students were able to experience all the lessons, Mrs. Rodriguez had a power lesson at the end to wrap up the mini lessons. The students were assessed with a written assignment in their journals. I had decided then that lesson study was for me. The next two years I was more involved as a teacher, and the focus subject switched to math. The first year the lesson study group focused on an area that kindergarten students will need in all grade levels, grouping. The lesson and preparation was created by the kindergarten teachers with the help of the group. The lesson was great the first time and the second time it was again a success. After the first lesson the group decided to allow the students more time deciding which grouping situations worked best. The teachers in the group that helped develop the lesson were also the ones that viewed and debriefed on the lesson. This is the same type of observations that have been used. The debriefing needed more focus on the lesson and not the students’ behavior, but that was something the group changed the next year. This year I was involved in two lessons one for my school and the Las Cruces lesson study group. At the school the group decided to focus in an area where the students did poorly on the test, geometry. I taught the second lesson, I was nervous and overwhelmed. The group developed the lesson and the preparation. After the first lesson taught the group noticed that there was only a little interaction between the students, as a result we grouped the students the next time. The group also noticed that we needed to change the questioning to higher end questions from the bloom’s taxonomy. The lessons were successful both times they were taught. During the Las Cruces lesson study I realized that as professional teachers we are all trying to reach the same goal. We all want our students to become independent thinkers, to be able to communicate using math vocabulary, and be successful. The Las Cruces goal is one that could have been used in any of the lessons I have been involved in. I enjoyed being a part of this lesson because I was able to see, outside of my district, teachers plan, critique, and teach their lessons. It is also comparable to the lessons I have been involved with in the sense of the planning and the teaching. However I think our group at Central Elementary needs to focus more on the lesson taught and also having outside observers that did not prepare the lesson. This type of observer is more subjective to the lesson taught and can add significant information needed to create a 18 better lesson. All the teachers involved in the developing of the lesson then become students learn how to improve their lesson for next time. 19 José E. Carrillo Reflection The Cobre Consolidated School District has been very supportive of the efforts at Central Elementary School and has invested substantially in the Lesson Study professional development process for the past 4 years. In my observations and going through this process of professional development, it appears to me that it has a very promising effect on student learning and teacher practice. I have specifically learned that the teachers in our group have become very knowledgeable about the Lesson Study process and want to continue to improve their practice. The first time I learned about lesson study was when I became the principal at Central Elementary School. I inherited this professional development model, given that a group of teachers had already started the process when I arrived at the school. I was invited to join the group and became very interested in the whole process. Unfortunately, I was not allowed to continue as an active participant because the collaborators from the university felt that my participation could hinder the reflection and collaboration process. Nonetheless my interest continued and I became passionate about the whole process and began to do my own research. I felt that lesson study was a very promising professional development approach for our staff and wanted to be a constructive supporter of their efforts. At the beginning of the following year, I was able to join in and help lead our Lesson Study efforts since some teachers wanted to continue even thought they were not sure that our grant was going to be renewed. Nonetheless, I continued to be an active participant and the research that I have done brings up many questions such as: “How does the lesson study process fit into the teachers’ existing work culture” (Friedman 2005). Patsy Wang-Iverson, Senior Scientist with research for Better Schools addressed the question “Why lesson study?” in a paper presented at the 2002 Lesson Study Conference. She also addressed the following questions. “What makes lesson study so different from other forms of professional development?” and “How does lesson study fit in with educational improvement?” (Wang-Iverson 2002). Wang-Iverson’s response is that lesson study is meaningful teacher collaboration “lesson study is not about studying a lesson in order to make a perfect lesson. Rather, it is a professional development process in which teachers systematically examine their practice in order to become more effective instructors and teacher collaboration and collegiality are central to this model” (Wang-Iverson 2002). She also states that the difference is “lesson study makes teacher collaboration concrete and focuses on a specific goal: better understanding of student thinking in order to develop lessons that advance student learning” (Wang-Iverson 2002). She says that “lesson study, which builds upon teachers’ shared knowledge and insight, supported by research, can help us overcome our own cognitive barrier concerning students’ ability to learn” (Wang-Iverson 2002). These and other questions have been for the most part positively answered or affirmed through our Lesson Study process at Central Elementary. As an administrator, I am always looking for better ways to assist teachers and staff in their own practice. I 20 certainly want all of our students and teachers to be successful. It is also my responsibility that teachers continue with their professional development. I want teachers to improve their practice and students to improve their learning. Furthermore, facilitating student learning is the essence of the education profession and I believe that improved student learning is possible through improved teacher practice. I believe that Lesson Study, through the collaborative efforts of groups such as the NMSU Lesson Study Project, has strong potential as being the professional development of choice in New Mexico as well as all over the United States and I want to be a knowledgeable constructive contributor in the reform effort. 21 Appendix 1 Instructional Resources 22 23 24 Rectangular Prism 25 Rectangular Pyramid 26 Triangular Prism 27 Triangular Pyramid 28 Pentagonal Prism 29 Pentagonal Pyramid 30 Appendix 2 Bibliography Mathematics 6B for Elementary School, Editors Heisuke Hironaka, Yoshishige Sigiyama, Publisher Tokyo Shoseki Co., Ltd., date of issue 2/20/2006.
