Pengembangan bahan ajar berbasis react (relating, experiencing, applying, cooperating, transferring) berbantuan advance organizer pada materi larutan penyangga untuk peserta didik SMA/MA kelas XI

Pemahaman konsep peserta didik terhadap materi larutan penyangga cukup rendah dan banyak kesulitan yang dialami oleh peserta didik terhadap beberapa konsep. Hal ini disebabkan karena penggunaan bahan ajar yang bersifat deskriptif. Bahan ajar kimia masih berupa buku teks yang menuntut peserta didik untuk menghafal bukan memperoleh pengetahuannya sendiri, sehingga berakibat pada hasil belajar peserta didik. Salah satu solusi untuk mengatasi permasalahan ini adalah mengembangkan bahan ajar dengan model pembelajaran berbasis kontekstual yaitu REACT karena sesuai dengan karakteristik materi larutan penyangga dengan melibatkan peserta didik dalam proses pembelajaran yang nyata. Adanya advance organizer dalam bahan ajar digunakan sebagai penguat struktur kognitif peserta didik yaitu memberikan gambaran mengenai keterkaitan antar konsep pada materi larutan penyangga. Penerapan model REACT berbantuan advance organizer diharapkan dapat membantu peserta didik mempelajari materi secara keseluruhan dan pembelajaran menjadi lebih bermakna. Penelitian dan pengembangan ini menggunakan model pengembangan Four-D oleh Thiagarajan, et all (1974) yang terdiri dari 4 tahapan yaitu define, design, develop, dan disseminate. Penelitian ini hanya sampai pada tahap ketiga yaitu develop. Produk yang dikembangkan berupa bahan ajar yang divalidasi oleh tiga validator yaitu satu orang dosen dan dua orang guru. Data yang dihasilkan berupa data kualitatif dan kuantitatif yang dianalisis dengan teknik analisis persentase dan deskripsi kualitatif. Hasil validasi terhadap buku guru dan buku peserta didik diperoleh rata-rata persentase kelayakan isi sebesar 85,60 persen, kelayakan penyajian dan bahasa sebesar 89,20 persen, serta kelayakan perangkat pembelajaran sebesar 86,70 persen. Hasil uji keterbacaan diperoleh rata-rata persentase aspek tampilan sebesar 92 persen, aspek penyajian materi sebesar 85,60 persen, dan aspek manfaat sebesar 94,80 persen. Berdasarkan kriteria kelayakan bahan ajar menurut Riduwan (2013), bahan ajar yang dikembangkan sangat layak digunakan sebagai sumber belajar.

An Experimental Study on the Optimization of Learners' Cognitive Load in Web-based Learning Environment

With the global epidemic of COVID-19, online teaching and learning have been carried out on a large scale all over the world, and MOOC has been further developed and applied. Through experiments, this study verified the feasibility of advance organizer strategy, eliminating redundancy strategy and ARCS model design strategy. The results are as follows. (1) In the Web-based learning environment, for the more difficult materials, it is beneficial to reduce the internal cognitive load of learners to provide a certain advance organizer before the learners start formal learning; but for the easier materials, whether or not to provide advance organizer has no significant impact on the learning results of learners. (2) In the Web-based learning environment, it is better to provide advance organizer for the more difficult knowledge by implanting background music into the Web-based learning environment; it can obviously hinder the learners' learning, but it is not obvious when the e-learners learn relatively simple knowledge. (3) In the Web-based learning environment, ARCS model design can stimulate the learning motivation of e-learners and optimize the cognitive load of e-learners.
