was clearly indicated that the lesson plans play a major role in
teaching as well as constructing the efficient learning environ-
ment (Clark & Dunn, 1991; Reiser & Dick, 1996; Shauelson,
1983 cited in Koszalka et al., 1999). The teachers’ preparation
in lesson plan is an important thing for determining teaching
goal, considering the existing resources, and designs the activ-
ity appropriately (Lee & Yakahashi, 2011). Fernandez and Yo-
shida (2004) stated that for lesson planning, basic problems of
students found in daily life were used as stimulators for stu-
dents to achieve goal. Moreover, it could change and support
the students to learn that lesson as well as plan for searching for
in order to find an appropriate approach through the students’
processes. Moreover, the students hope to solve different prob-
lems. Therefore, the basic problems in daily life would help
them to accomplish the lesson objective.
In present situation, teachers still have bad attitude towards
lesson planning. Although they have approved that the lesson
plan is useful as developmental plan of every teacher’s instruc-
tional management quality which was the responsibility of each
teacher. Each of them has accusation that one had to teach
many subjects, many periods, also be responsible in other kinds
of work. Another major cause of them to feel bored with lesson
planning is the process enhancing the establishment of lesson
planning which is not based on principles of sufficiency, ap-
propriateness, and unsystematic and hierarchical development
(Kamkerd, 2004).
The most frequently used one of lesson plans using in gen-
eral class is the class with teacher-centered leader of learning.
The students receive knowledge from the teachers. The teachers
are knowledgeable in many aspects, and use the knowledge
feeding technique for students by lecturing and explaining for
the students throughout the time. They perform activities them-
selves without providing opportunity for students to pick up or
touch the instructional media shown by teachers. The students
do not have a chance to speak, or work in group to search for
answer. Most of them use media included chalk and blackboard.
In contrast, in the lesson study innovation classes are the
classes facilitating the new instructional management which
cause the students to have freedom to learn either in group or
individual with the teachers as their consultants. In this kind of
classroom management, teacher is the monitor and advisor for
the students and the students play their role and learn from
media. Therefore, this kind of classroom management was
congruent with curriculum objective which wants the students
to search for, analyze and critique, and practice every step until
they could lean by themselves (Rattanasomboon et al., 2010).
Research Methodology
This research was a qualitative research. Data were presented
by descriptive analysis in context of schools under the project
of Mathematics Teaching Professional Development through
the Lesson Study and Open Approach. The Lesson Study was
implemented based on Inprasitha’s (2010) including 3 phases of
implementation including phase 1) Collaboratively design re-
search lesson, phase 2) Collaboratively observing the research
lesson, and phase 3) Collaboratively reflection on teaching
practice. The first phase is the phase that the teacher and in-
ternship students in school collaborate in planning the lesson
together, would be emphasized.
1) Target Group
This study was the study in lesson planning of the Lesson
Study group participating in the project of Lesson Study and
Open Approach for 6 years, as the schools using Lesson Study
continuously, using data collection by participatory observation
in lesson planning step which was depend on the type of lesson
planning.
The target group of this study, consisted of the in-service
teacher with responsibility in teaching, teacher observer in
mathematics subject of grade 1, the internship student in mathe-
matics education with responsibility as teacher and teacher
observer in mathematics subject of grade 1, the researcher or
research assistant from Center for Research in Mathematics
Education, Faculty of Education, Bung-neum-bung-krai-nun
School, Muang District, Khonkaen Province, a school under the
Project of Teaching Professional Development based on Lesson
Study using learning management through Lesson Study and
Open Approach.
2) Research Instruments
In conducting this research, the researcher used 2 kinds of
Instruments: the instrument using for data collection, and the
instrument using for data analysis, as follows:
a) The Activity Record Form in collaborative establishment
of knowledge management plan was constructed by Center for
Research in Mathematics Education, as an instrument using for
collecting data during knowledge management planning
(Mathematics Education, Faculty of Education) in 4 major is-
sues.
b) The Field Note, used by taking note of spoken words and
opinion expression during the phase of collaborative establish-
ment in teaching observation, and reflection.
c) The audio-tape recorder was an instrument for recording
sound during the phase of collaborative observation and reflec-
tion.
d) The video-tape recorder, used for recording collaborative
lesson planning from the beginning of planning
3) Data Analysis
Qualitative data analysis was administered in this study. The
researcher used protocol data from the step of collaborative
establishment of lesson, collaborative observation, and col-
laborative reflection obtaining from deciphering audio tape and
video tape recorder, field note, activity record form from col-
laborative establishment of learning organization plan, and
students’ performance in order to have complete and clear in-
formation to be analyzed. Data were analyzed based on frame-
work of lesson planning of Stigler and Hiebert (1999), and
presented in descriptive analysis.
Results
In school context using Lesson Study and Open Approach,
lesson planning was a guideline helping teachers, and a model
in implementing classroom activity. Inprasitha (2010) stated
that the major process of Lesson Study was the collaborative
planning for teaching in group. Then, the teacher in Lesson
Study group used the lesson plan in classroom context of
school using Lesson Study and Open Approach based on Inpra-
sitha’s (2010) approach including 3 phases of implementation:
Phase 1; Collaboratively design research lesson, Phase: Col-
laboratively observing the research lesson, and Phase 3; Col-
laboratively reflection on teaching practice. The researcher
presented research findings based on Stigler and Hiebert (1999)
approach as follows:
