ABSTRAK

Penelitian ini bertujuan untuk mengetahui kelayakan lembar kerja peserta didik (LKPD) dengan strategi mind mapping pada materi ikatan kimia yang ditinjau dari validitas isi dan konstruk melalui hasil validasi oleh para ahli, kepraktisan melalui aktivitas peserta didik dan respon peserta didik, serta keefektifan melalui peningkatan hasil penilaian mind mapping dan hasil belajar peserta didik. Jenis penelitian ini merupakan penelitian pengembangan model 4-D dengan empat  tahap yaitu, pendefinisian (define), perancangan (design), pengembangan (development), dan penyebaran (disseminate), yang dibatasi hanya sampai pada tahap pengembangan (develop). LKPD diujicobakan terhadap 15 peserta didik kelas X SMA Negeri 1 Krembung Sidoarjo. Hasil penelitian menunjukkan LKS yang dikembangkan valid ditinjau dari validitas isi memperoleh persentase sebesar 90,67% serta validitas konstruk memperoleh persentase sebesar 90,83%. Kepraktisan ditinjau dari hasil observasi aktivitas peserta didik selama tahap uji coba LKPD dengan persentase sebesar 90,39% dan respon peserta didik terhadap masing-masing kriteria yaitu kriteria isi sebesar 88,89%, kriteria kebahasaan 86,67%, kriteria penyajian 90,47%, kriteria mind mapping sebesar 95,55%. Keefektifan yang ditinjau dari peningkatan hasil penilaian mind mapping melalui skor N-gain 20% mengalami peningkatan dengan kriteria sedang dan 80% dengan kriteria tinggi dan hasil belajar peserta didik mengalami peningkatan sebesar 26,67% dengan kriteria sedang dan 73,33% dengan kriteria tinggi.

ABSTRACT

The purpose of this research is determine the feasibility of student worksheets with mind mapping strategies on chemical bond material that are viewed from validity contains and construct through the results of validation by experts, practicality through student activities and student responses, and effectiveness through increasing results mind mapping assessment and student learning outcomes. This type of research is a 4-D model development research with four stages, namely, define, design, develop, and disseminate, which is confined only to develop stage. Student worksheets was tested on 15 students of 10^th grade of SMA Negeri 1 Krembung Sidoarjo. The results showed that validally developed worksheets viewed from content validity obtained a percentage of 90.67% and construct validity obtained a percentage of 90.83%. Practicality in terms of observations of the activities of students during the testing phase of the student worksheets with a percentage of 90.39% and responses of students to each criterion, the content criteria of 88.89%, language criteria 86.67%, presentation criteria 90.47 %, mind mapping criteria are 95.55%. The effectiveness seen from the increase in mind mapping assessment results through 20% N-gain score has increased with moderate criteria and 80% with high criteria and student learning outcomes have increased by 26.67% with moderate criteria and 73.33% with high criteria.
