Pengembangan Perangkat Pembelajaran Materi Lingkaran Berbasis Discovery Learning Untuk Meningkatkan Kemampuan Penalaran Matematis Siswa Kelas VIII SMP

---

This research is motivated by the demands of the 2013 curriculum on
teachers. Teachers are required to not only teach and educate, but must be able to
become facilitators so that the role of education becomes more meaningful.
Teachers must be able to design learning processes that are interactive, inspiring,
fun, challenging and motivating students to actively participate in the learning
process. Learning planning is designed in the form of syllabus and lesson plans.
Mathematical reasoning ability must be possessed by students, but in reality
students' mathematical reasoning abilities are still low. There are still
shortcomings in teaching materials in the circle material which is also the
background for the author to develop LKPD. The solution to improve the learning
process and students' mathematical reasoning is to develop learning tools based
on the discovery learning. This is because the discovery learning in accordance
with the learning theory proposed by Brunner, namely the learning process will
run well and creatively, if the teacher gives students the opportunity to find a rule
(including concepts, theories, definitions, etc.) describe/represent the rule that is
the source.
The development model used is a 4-D model. The data collection
instruments in this study were in the form of validation sheets, student response
questionnaire sheets, teacher response questionnaire sheets, and students'
mathematical reasoning ability tests. The 4-D model consists of four stages of
development, namely; (1) the defining stage (define) is carried out on: (a)
preliminary-late analysis, namely conducting interviews with teachers and
studying documentation related to learning devices used in the learning process,
(b) student analysis, which is carried out by conducting observations and
interviews with participants. students related to students' mathematical reasoning
abilities, (c) At the stage of material analysis carried out in this study, it was
adjusted to the curriculum used by SMPN 4 Tambang. The curriculum used is the
2013 curriculum. Based on the 2013 curriculum, one of the materials studied by
class VIII students is circles, (d) In the task analysis stage, the researcher
analyzes KD related to the circle material. The analysis was carried out as a
reference for compiling the competency achievement of the selected KD, (e) At the
learning objective analysis stage, the researcher summarized the results of the
task analysis and material analysis used as a guide in compiling the Syllabus,
RPP, and LKPD on the circle material; (2) the planning stage (design),
researchers design learning tools by making an initial format consisting of six
meetings with the scope of the material, namely: (a) circle elements (b)
circumference of a circle (c) area of a circle (d) angular relationships the center
with the angles of the circumference of a circle facing the same arc (e) the
relationship of the central angle to the length of the arc of the circle (f) the
relationship of the central angle, arc length, and area of the circle; (3) the
development stage (develop), researchers develop learning tools according to the
vi
initial format that has been compiled, then validated by three validators. The results of the analysis of the validation of the syllabus, lesson plans, LKPD, and students' mathematical reasoning abilities show a very valid category with a score of 87.06%, 87.39%, 87.02%, 85.28%, meaning that the learning tools developed can tested and revised according to the validator's suggestion, then the researcher tested the revised learning device to small groups consisting of 9 students who had heterogeneous abilities to see the practicality of the developed worksheets.
The results of practicality data analysis in small group trials from student response questionnaires showed a very practical category by obtaining a score of 95.68%, meaning that the learning tools developed could be tested in large groups and revised according to the students' suggestions, then the researchers tested the devices. revised learning to large groups consisting of 30 students who have heterogeneous abilities to see the practicality and effectiveness of the developed learning tools in the form of syllabus, lesson plans, LKPD, and students' mathematical reasoning ability tests. The results of practicality data analysis from student and teacher response questionnaires with scores of 98.02%, 96.5% respectively and the effectiveness of the students' mathematical reasoning ability test results with a score of 1.206 indicates a very practical and more effective category, meaning discoverylearning that is applied is more effective on mathematical reasoning abilities in class VIII junior high school students; and (4) dissemination (disseminate), researchers use learning tools on a wider scale, namely in the results of seminars and in the preparation of articles to be published in journals.
Learning tools that have been revised are then used as products of research results.-based circular learning tools discovery learning to improve the mathematical reasoning abilities of eighth grade junior high school students are valid, practical, and effective.
