Kemampuan siswa dalam mengkomunikasikan konsep-konsep fisika terutama secara visual dirasakan sangat kurang. Hal tersebut berdasarkan hasil observasi awal di kelas VIII - C SMP Laboratorium Percontohan UPI semester 1 tahun pelajaran 2006/2007, yang hanya 17,6 % siswa aktif mengungkapkan ide-idenya baik melalui lisan, tulisan maupun gambar, 88,2 % siswa menyatakan kesulitan memahami konsep-konsep fisika terlebih lagi kalau sudah menyelesaikan soal-soal yang berhubungan dengan pe$amaan matematis, dan rata-rata nilai ulangan siswa (UTS) hanya mencapai 34,10 %. Kesulitan lain yang dirasakan guru adalah ketika mengkondisikan siswa aktif dalam proses pembelajaran. Mengatasi kenyataan tersebut dilakukan penelitian kolaboratif melalui kemitraan dengan jurusan pendidikan fisika dalam kegiatan Lesson Study pada metode Penelitian Tindakan Kelas (PTK) dengan model pembelaiaran kooperatif, yang di khususkan dalam meningkatkan kemampuan siswa melalui komunikasi visual. Hasil yang diperoleh ternyata terjadi peningkatan rata-rata komunikasi visual siswa tiap siklus sebesar 46,22 %, dan peningkatan rara-rata prestasi belajar siswa tiap siklus sebesar 49,50 %. Adapun komunikasi visual yang paling banyak dilakukan siswa setiap siklusnya yaitu pada aspek menyajikan gambar dengan indikator menyatakan data hasil penginderaan ke dalam bentuk gambar sebesar 46,67 % untuk siklus satu, 62,22 % untuk siklus dua, dan 71,11 % untuk siklus tiga. Sedangkan komunikasi visual yang paling sedikit dilakukan siswa yaitu pada aspek menstranfer gambar dengan indikator mampu menyatakan konsep dalam bentuk gambar sebesar 13,33 % untuk siklus satu, 26,67 % untuk siklus dua, dan 48,89% untuk siklus tiga.

Students' mental models are important to be analyzed properly. Mental models are able to be described for studentsâ€™ knowledge and diagnosed studentsâ€™ learning difficulties. This study aims to analyze students' mental models on work and energy concept in the post-pandemic covid-19 era. Students' mental models were measured by four-tier test instrument and analyzed using the wright map. The research study utilizes descriptive-quantitative research method. The participant of this study are 31 K-10 students (13 boys and 18 girls) at high school in the West Java, Indonesia. The data analysis shows that the most student had category of in (51.52%), Sy-D (18.52%), furthermore caterogy Sy-C (13.52%), Sy-B (11.29%), and only less students that had category of Sy-A (2.95%) and Sc (2.2%). It could be concluded that physics learning in forming students' mental models needs to be improvised immediately.

This paper aimed to assess the validity of the Sound Wave Four Tier (SOFT) Diagnostic Test that can be used to identify students' conception profiles. Using the Four Design (The participants were 42 students aged 15-17 years old in one of the public high schools in Bandung City. The participants were 42 students aged 15-17 in one of the public high schools in Bandung City. The data's validity, the instrument's reliability, and the distribution of students' conceptions were analyzed using the Rasch model with the MINISTEP 4.5.3.0 program. The dimensional-based validity of the items used was valid. Accuracy based on Cronbach Alpha (α) was in the high category, the item reliability score was in the good category, and the reliability of personnel was in the low category. The conception profile of the students categorized as. Sound Understanding (SU), Partial Positive (PP), Partial Neutral (PNt), Partial Negative (PNg), Misconception (MC), No Understanding (NU), and No Coding (NC). The highest category of conception found was MC. There were a lot of misconceptions found in the sound wave material. Students' Misconceptions are still commonly found in sound waves. A 4D model can be developed using Rasch modeling analysis to identify students' profiles. Utilizing the SOFT instrument enables students to gain a broader understanding of the concept, including verbal statements and various representations of images and mathematical symbols.
