Salah satu kemampuan abad 21 yang harus dikuasai siswa adalah kemampuan berpikir kritis. Untuk mengetahui tingkat keberhasilan siswa dalam mengembangkan kemampuan berpikir kritis, diperlukan suatu instrumen yang dapat mengukur kemampuan tersebut. Artikel ini memperkenalkan penggunaaan Rasch Model untuk mengembangkan instrumen pengukuran kemampuan berpikir kritis siswa pada topik kimia, terutama topik ikatan kimia. Berdasarkan analisis Kompetensi Dasar (KD) dan Indikator Berpikir Kritis, indikator soal dirancang. Berdasarkan indikator soal, butir soal beserta kunci jawaban dan pedoman penskoran dikembangkan. Instrumen terdiri dari 13 soal tipe uraian yang divalidasi oleh dua orang pakar dan direvisi berdasarkan masukan yang diberikan. Instrumen diujicobakan kepada 51 siswa SMA di Tanjungpinang. Model Rasch parsial-kredit diterapkan pada data hasil uji coba untuk memeriksa kualitas tiap butir soal dan kualitas instrumen secara keseluruhan. Hasil analisis menunjukkan bahwa 12 dari 13 item soal memenuhi kriteria soal yang baik menurut Rasch Model dengan reliabilitas instrumen 0,72 (cukup). Studi ini menunjukkan bahwa penggunaan Rasch model untuk mengembangkan instrumen pengukuran kemampuan berpikir kritis dalam bidang kimia cukup menjanjikan.

Pada umumnya peserta didik cenderung belajar dengan hafalan daripada secara aktif mencari tahu untuk membangun pemahaman mereka sendiri terhadap konsep ilmu kimia. Adapun tujuan dari penulisan artikel ini adalah untuk mengetahui tingkat kemampuan berfikir peserta didik melalui pembelajaran kontekstual dan untuk membangun pembelajaran bermakna yang diterapkan melalui model pembelajaran contextual teaching and learning (CTL) untuk kimia di SMA. Kita ketahui pada pembelajaran kimia terutama pada materi-materi tertentu bersifat abstrak akibatnya peserta didik tidak mampu menghubungkan konsep yang diperlukan untuk memahami konsep yang lain. Untuk menjawab permasalahan tersebut, diperlukan suatu strategi pembelajara yang dapat digunakan pendidik, yaitu salah satunya model pembelajaran contextual teaching and learning (CTL)

One effort to improve student learning outcomes is to choose teaching media that are appropriate and attract students' attention. The media developed is a three-dimensional ball teaching media.The purpose of this study is to develop three-dimensional atomic ball teaching media, to find out the validity level of three-dimensional atomic ball teaching media, to find out the practicalities of the three-dimensional atomic ball teaching media that have been developed. This research is a type of Research and Development (R & D) research using a 4D development model, namely define, design, develop, and dessiminatebut is limited to the develop stage. The teaching media developed were validated by media experts and material experts. The subject of this research trial was a chemistry teacher to find out the practicality of three-dimensional atomic balls teaching media, and 20 students of East Siantan 1 High School to find out the practicality of three-dimensional atomic balls. The method used to analyze data uses qualitative and quantitative descriptive techniques. The results showed that the validity of three-dimensional atomic ball teaching media for atomic structure material was obtained from the results of a media expert's assessment of 95.19% with very valid criteria, and the material expert's assessment was 81.23% with very valid criteria.The practicality test results were obtained from teacher responses of 92.5% with very practical criteria, and 81.41% student responses with very practical criteria. Based on the results of the study it can be concluded that atomic ball teaching media in three dimensions of atomic structure are worthy of being used as learning media by teachers and students.

Berdasarkan analisis kebutuhan yang telah dilakukan, kurangnya media pembelajaran menjadi salah satu permasalahan yang terjadi di tingkat sekolah menengah atas, khususnya pada mata pelajaran kimia, terutama pada materi faktor-faktor yang mempengaruhi laju reaksi. Penelitian ini bertujuan untuk mengembangkan multimedia interaktif dengan konteks kemaritiman pada materi faktor-faktor yang mempengaruhi laju reaksi. Pengembangan dilakukan dengan menggunakan model pengembangan Alessi dan Trollip dengan tiga tahapan yaitu tahap perencanaan, perancangan, dan pengembangan. Untuk mengukur kualitas multimedia interaktif dilakukan uji validitas dan uji praktikalitas. Hasil validasi media dan materi pada multimedia interaktif dengan konteks kemaritiman pada materi faktor-faktor yang mempengaruhi laju reaksi diperoleh hasil 89.28% dan 84.37% dengan kategori sangat valid dan layak diujicobakan kepada guru dan peserta didik. Hasil praktikalitas multimedia interaktif dengan konteks kemaritiman pada materi faktor-faktor yang mempengaruhi laju reaksi terhadap guru dan peserta didik diperoleh 87.5% dan 82% dengan kriteria sangat praktis.
