Furthermore, the findings show that teachers’
development and experiences in participating lesson
study activities helps them to select the most suitable
learning content, process, product, and environment.
In terms of content knowledge, the observation was
conducted to find out if the teacher had adequate
prerequisite knowledge, if he had adequate
knowledge about teaching materials, if he could link
the materials of different subject matters within a
single theme, if he could tell general knowledge
(acquired from textbooks) from specific knowledge
(usually acquired from experience) available in the
teaching materials. In terms of pedagogical
knowledge, the observation was conducted to find out
if the teacher could adjust the teaching pattern to the
students’ knowledge, if he could accommodate what
students need, if he could execute the lesson plan, if
he could organize the classroom activities, if he could
implement the integrated thematic instruction, if he
could carry out an authentic and integrated
assessment of students’ achievements. In terms of
PCK, the observation was conducted to find out the
teacher’s selection of teaching method and approach
relevant to the materials, if the teacher could tell the
content students had a difficulty with from that they
find it easy to understand, and if the material delivery
was appropriate and student-friendly.
However, even though the findings present that
the development and experiences have not seen in all
indicators, but teachers show that the teacher
mastered the material, the concept, and the
interrelations between different materials within a
particular theme. The teacher was able to develop
teaching materials and their interrelations, develop
integrated assessment, and develop the reflective
action ability. The students were asked to identify
some objects in the classroom that related with the
current learning topic.
5 CLOSING REMARK
The study shows that modified lesson study
integrated with PCK gives positive impact in the
teacher’s development, ability towards some thematic
content and students understanding ability. The result
indicated that the teacher mastered the material, the
concept, and the interrelations between different
materials within a particular theme. The teacher was
able to develop teaching materials and their
interrelations, develop integrated assessment, and
develop the reflective action ability.
