Abstract

Banyak calon guru maupun guru mengalami kesulitan dalam mempersiapkan perangkat terintegrasi model pembelajaran sesuai tuntutan kurikulum, yang mengharuskan guru melakukan kegiatan kelas berpusat kepada peserta didik. Guru pada umumnya dengan mudah bisa menentukan sintaks suatu model namun belum mampu menerapkan dalam suatu desain pembelajaran. Pengalaman membimbing mahasiswa calon guru dan peserta PPG selama beberapa tahun juga menunjukkan hal yang sama. Untuk memecahkan masalah ini dipandang perlu  pengembangan perangkat pada mata kuliah strategi pembelajaran kimia berupa LKM yang valid, praktis dan efektif pada materi pokok pengembangan pembelajaran dengan menerapkan model yang dipilih sesuai materi. Metode penelitian yang digunakan adalah Research Development, yang terdiri dari 4-P yakni pendefinisian, perancangan, pengembangan dan pendesiminasian. Penelitian yang dilaksanakan hanya sampai pada tahap pengembangan. Data penelitian didapatkan dari hasil validasi pakar pendidikan kimia, observasi, wawancara dan analisis hasil uji coba. Hasil penelitian menunjukkan perangkat LKM beralur Discovery Learning yang dikembangkan memenuhi kriteria valid dari segi isi dan konstruksi. Hasil uji coba memenuhi kriteria praktis karena mahasiswa dapat menggunakan LKM dengan baik tanpa kendala yang berarti dan melalui angket, mahasiswa memberikan respon positif terhadap LKM.

Abstract

This research aims to develop a Student Activities Worksheet Based on the MEA Model on the ionic equilibrium and pH of buffer solution material for grade XI SMA/MA. Student Worksheet Based are designed according to the stage of the MEA learning model. The type of this research is research and development (R and D) about the development process of 4-D. The object of this research is student activities worksheets based on MEA. The data collection is the validation user response questionnaire. The validity of the content aspect obtained the result of data analysis, characteristics of MEA, language aspect, serve aspect, and visual aspect are 96.43%, 93.33%, 85.41%, 97.22%, 97.91% with valid category. Student activities worksheets validated by the validators tested to 25 students and three teachers. The test responses by 25 students and three chemistry teachers included very good criteria, with each score of 95% and 80.33%. Based on the result of data analysis, student activities worksheets based on MEA of ionic equilibrium and pH of a buffer solution produced are valid.

Abstract

This Research aims to develop a digital student worksheet for hybrid learning that is valid and practically reviewed based on student responses as users. Digital student worksheet can be used as teaching materials that help students in hybrid learning. This research and development consist of three stages, namely define, design, and develop. The research data was obtained through a validation sheet by two expert validators based on aspects of content feasibility, aspects of didactic feasibility, aspects of language feasibility, aspects of presentation feasibility and aspects of graphic feasibility with response questionnaire for digital worksheet users. Based on the results of expert validation, the percentage are 93.75% on content feasibility; 83.33 % on didactic feasibility; 89.58% on language feasibility; 83.33% on presentation feasibility; and 83.33% on graphic feasibility. The percentage as result of questionnaire for digital worksheet users is 89.47%. Students’ responses as users show that digital worksheet is practical, easy to access, and can increase interest in learning. So, the average of digital worksheet validity percentage is 86.66% and it can be concluded that the digital student worksheet for hybrid learning which is developed using the Microsoft Sway application is categorized as very valid and can be used as a learning media.
