Pengembangan Perangkat Pembelajaran Menggunakan Model Problem Based Learning Pada Materi Program Linear Dua Variabel Untuk Memfasilitasi Kemampuan Pemecahan Masalah Matematis Peserta Didik Kelas XI SMA

---

Students’ mathematical problem-solving skills in Indonesia are still low
and this motivates the researcher to conduct this study. The students’
mathematical problem-solving skills can be improved by utilizing learning models
that can facilitate students to construct their knowledge. The results of the
observations on some senior high schools in Pekanbaru showed that teachers still
used conventional teaching methods causing many students were not actively
engaged in the learning process. This study aims to develop a mathematics
learning instrument with a problem-based learning (PBL) model using twovariable
linear program materials that meet valid and practical criteria to
facilitate students' mathematical problem-solving skills. This research and
development (R&D) used a 4-D model, namely define, design, develop, and
disseminate. The developed learning instrument in this study was in the form of a
syllabus, lesson plans, and worksheets.
The define stage covered some phases. The first phase was the initial-end
analysis in which the researcher found the problems in schools, namely
conventional learning processes that make students inactive. The next phase was
the student analysis stage in which the researcher found the students' skills
through the last math test scores. In the task analysis phase, the researcher
decided to take the two-variable linear program material in Basic Competence
3.2 and 4.2 in mathematics for the XI grade students in senior high schools in
accordance with the Minister of Education and Culture Regulation Number 37 of
2018. In the concept analysis phase, the researcher determined four main
materials for students, namely linear inequalities in two variables, a two-variable
linear program, determining the optimum value with the corner point test, and
determining the optimum value with the probing line test. The last phase was goal
analysis in which the researcher formulated learning objectives to be achieved
using the developed learning instrument.
The design stage covered some phases. The first phase was the media
selection in which the researcher chose PowerPoint to supplement the
worksheets. The next was the format selection phase in which the researcher
arranged the format of the syllabus, lesson plans, and worksheets in accordance
with the Minister of Education and Culture. The last phase was the initial design
in which the researcher arranged the initial design of the developed learning
instrument.
The development stage consisted of some phases, namely expert
assessment or validation tests, readability tests, and practicality tests. The test
instruments used validation sheets and questionnaires. A learning instrument is
considered valid with a minimum score of 70.01% and practical with a minimum
score of 60.01%.
The results of each test at the development stage were analyzed and the
overall average result of the validation test for syllabus, lesson plan, and
xvi
worksheet respectively reached 89.91%, 89.66%, and 86.67% with a very valid
category. After the validity test met the minimum value and valid category, it
continued with the readability test. The readability test involved 9 students
obtaining an average readability score of 88.67% with the good category. The
learning instrument that had been tested for readability was then tested for
practicality on 21 students in Grade XI of Natural Science 1 with an average
practicality score of 89.75% in the very practical category.
