Miskonsepsi seringkali terjadi pada mata pelajaran yang bersifat abstrak. Beberapa materi yang terdapat pada mata pelajaran Kimia bersifat abstrak, seperti materi bilangan kuantum dan konfigurasi elektron. Salah satu cara yang dilakukan untuk mengetahui tingkat miskonsepsi siswa terhadap materi perlu dilakukan penelitian dengan menggunakan tes diagnostik three tier multiple choice (TTMC). Tes diagnostic TTMC pada materi bilangan kuantum dan konfigurasi elektron belum banyak dikembangkan, sehingga pengembangan tes diagnostik TTMC pada materi bilangan kuantum dan konfigurasi elektron perlu disusun terlebih dahulu. Pengembangan instrumen soal tes diagnostic TTMC pada penelitian ini dilakukan melalui tiga tahap, yaitu pengembangan butir soal, validasi butir soal, dan ujicoba butir soal kepada peserta didik. Hasil penelitian diperoleh 21 butir soal valid dan reliabel dengan nilai CVR 1.00. Miskonsepsi tertinggi pada materi bilangan kuantum dan konfigurasi elektron ditemukan pada sub konsep menentukan seperangkat bilangan kuantum dari suatu orbital. Perbedaan miskonsepsi tertinggi antara kelas X IPA dan X imersi terdapat pada sub konsep menentukan seperangkat bilangan kuantum dari elektron pada tingkat energi tertinggi.

The purpose of this research is to design a four-tier diagnostic test instrument on electron configurations and quantum numbers that can be used to analyze misconceptions. The four-level diagnostic test instrument is an assessment instrument that functions to assess students' conceptual comprehension in understanding a subject matter. The four tier test has four levels, namely knowledge questions, confidence questions in completing questions, reasons for answering questions, and confidence in giving reasons. This study uses a descriptive qualitative method with the stages of analyzing the problem, collecting data, product design, validating the design, and conducting instrument trials. The results showed that the designed diagnostic instruments were feasible and reliable. Instrument test results indicate that indicator a) determines the magnitude of the four quantum numbers (n,ℓ,mℓ, ms) in an orbital; b) identify the characteristics and functions of the azimuth quantum number (ℓ); c) determine the spin magnetic quantum number (ms) of the electron in the orbital; and d) determine the spin magnetic quantum number (ms) of a single electron in an orbital, which is the most misunderstood.

This research aims to determine the effect of STEAM Project-based chemistry learning assisted by ChemSketch on the learning outcomes and creative thinking abilities of students at SMA N 1 Kendal. This research is quantitative research using the Quasi Experimental method. The quasi experimental design in this research is nonequivalent control group design. Samples were taken using cluster random sampling technique. The population of this study was all students in class XII MIPA SMA N 1 Kendal. Chemistry learning using the STEAM Project approach has a moderate effect in improving student learning outcomes as evidenced by the t-test value of the difference between two average learning outcomes of 0.031 (sig. (2 tailed) < 0.05) which means Ha is accepted and the Effect Size test of 0.53. Meanwhile, the STEAM Project approach in this research had no effect on students' creative thinking abilities due to the lack of variety of questions and limited time during learning. This is proven by the t-test, the difference between the two average creative thinking abilities is 0.109 (sig. (2 tailed) > 0.05).

Media pembelajaran belum dimanfaatkan secara optimal menjadi salah satu penyebab rendahnya pemahaman konseptual siswa. Salah satu media pembelajaran yang dapat digunakan untuk membantu mengoptimalkan kemampuan dalam mengingat dan memahami suatu materi yaitu media develabs. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan media pembelajaran devlabs terhadap peningkatan pemahaman konsep siswa pada materi larutan penyangga. Penelitian ini merupakan jenis penelitian quasi ekperimental research dengan desain non-equivalent control group design. Penelitian ini dilakukan di SMA N 1 Kaliwungu Kendal, sampel pada penelitian ini adalah siswa kelas XI MIPA 3 dan XI MIPA 5. Teknik sampling yang digunakan yaitu claster random sampling. Teknik analisis data pada penelitian ini yaitu analisis pemahaman konsep, uji perbedaan dua rata-rata, uji pihak kanan, dan uji effect size. Hasil penelitian menunjukkan terjadi peningkatan pemahaman konsep siswa setelah menggunakan media pembelajaran devlabs dengan uji independent sampel t-test yaitu 0,000 < 0,05. Hasil uji effect size sebesar 3,80% dengan Kategori “tinggi”.

Development of the Mobile Learning Based on Augmented Reality and Unity of Sciences at Stoichiometry Lessons Penelitian ini merupakan penelitian pengembangan dengan model ADDIE (analysis, design, development, implementation, evaluation). Tujuan penelitian ini adalah untuk mengetahui kelayakan dari media pembelajaran yang dikembangkan. Pada penelitian pengembangan ini, materi stoikiometri diintegrasikan dengan Augmented Reality dan Unity of Sciences. Untuk menguji kelayakan dilakukan oleh 3 validator yakni ahli materi dan ahli media. Instrumen yang digunakan adalah angket. Angket tersebut meliputi angket kelayakaan dari segi media dan angket kelayakan dari segi materi. Berdasarkan hasil penelitian diperoleh bahwa presentase untuk aspek tampilan yakni 81,94%, presentase aspek pemrograman yakni 80,00% dan presentase pada aspek keterpaduan isi materi yakni 82,77%. Sehingga rata-rata persentase kelayakan baik dari penilaian aspek media dan materi adalah 81,77% dengan kategori sangat layak.
