Pengaruh implementasi Word Wall melalui LKPD berbasis Problem Solving terhadap hasil belajar dan motivasi belajar pada pembelajaran materi sistem saraf manusia

The nervous system in humans is a concept that is difficult to observe and many biological terms are not common for students, so learning media is needed that can help learning. One of the interactive media that can be used in the learning process is Word Wall and LKPD with problem solving model. This research aims to (1) examine the effect of Word Wall implementation through problem solving-based LKPD on student learning outcomes and (2) describe the implementation of Word Wall through problem solving-based LKPD affects student learning motivation. The research is a quasi experiment with a research design of nonequivalent control group design. The research samples were XI-1 (experimental class) and XI-2 (control class). Data analysis techniques using Wilcoxon Signed Ranks Test and descriptive. The results showed (1) there was an effect of Word Wall implementation through problem solving-based LKPD on product learning outcomes, namely Sig. <0.001, process learning outcomes, psychomotor learning outcomes, and affective learning outcomes are in the high category. (2) The implementation of Word Wall through problem solving-based LKPD on student learning motivation in the experimental class has an average value of 32.13 which shows that it is in the high category. This shows that the implementation of Word Wall through problem solving-based LKPD is expected to improve learning outcomes and student motivation in learning biology in high school.Sistem saraf pada manusia merupakan konsep yang sulit diamati dan banyak istilah biologi yang tidak umum untuk peserta didik, maka dibutuhkan media pembelajaran yang bisa membantu pembelajaran. Salah satu media interaktif yang bisa dipakai pada jalannya proses pembelajaran yaitu berupa Word Wall dan LKPD dengan model problem solving. Penelitian ini bertujuan agar dapat (1) menguji pengaruh implementasi Word Wall melalui LKPD dengan basis problem solving terhadap hasil belajar peserta didik dan (2) mendeskripsikan implementasi Word Wall melalui LKPD berbasis problem solving berpengaruh terhadap motivasi belajar peserta didik. Penelitian merupakan penelitian quasi experiment melalui sebuah desain penelitian nonequivalent control group design. Sampel penelitian yaitu XI-1 (kelas eksperimen) dan XI-2 (kelas kontrol). Teknik analisis data menggunakan Uji Wilcoxon Signed Ranks Test dan deskriptif. Hasil penelitian menunjukkan (1) terdapat pengaruh implementasi Word Wall melalui LKPD berbasis problem solving terhadap hasil belajar produk yaitu Sig. < 0,001, hasil belajar proses, hasil belajar psikomotorik, dan hasil belajar afektif berada pada kategori tinggi. (2) Implementasi Word Wall melalui LKPD berbasis problem solving terhadap motivasi belajar peserta didik pada kelas eksperimen memiliki nilai rata-rata 32,13 yang menunjukkan ada pada kategori tinggi. Hal ini menampilkan jika implementasi Word Wall melalui LKPD berbasis problem solving diharapkan dapat meningkatkan hasil belajar dan motivasi belajar peserta didik pada pembelajaran biologi di SMA.
