Study on students' mental model's analysis was done to identify misconceptions about solubility equilibria concept. The method employed in the study was a case study uses a qualitative approach. The participants were 23 students of class XI of a senior high school in Bandung. The instrument used in the study was the Diagnostic Test on Mental Model-Prediction, Observation, Explanation (TDM-POE). The results showed that there were diverse of students' misconceptions about the precipitate formation of a reaction, the effect of common ions and decrease in pH on solubility. Based on the results of the study, many misconceptions occur in the subconcept of the effect of common ions on solubility. Misconceptions arise because students have incomplete mental models at the submicroscopic level.

ABSTRAKTelah dilakukan penelitian yang menghasilkan representasi kimia berbasis intertekstual berupa multimedia pada sub-konsep konfigurasi elektron berdasarkan model atom Bohr yang diperluas. Dalam penelitian ini digunakan metode deskriptif dan evaluatif yang merupakan bagian dari Penelitian dan Pengembangan (R D). Prosedur penelitian dilakukan melalui beberapa tahapan kerja, yaitu: (1) penentuan materi subjek, (2) kajian standar kompetensi dan kompetensi dasar yang terdapat pada standar isi serta contoh silabus BSNP untuk menentukan indikator dan konsep, (3) pengumpulan multimedia existing, (4) analisis multimedia existing berdasarkan kajian aspek konten, pedagogi, dan multimedia, (5) pembuatan script dan storyboard yang divalidasi berdasarkan aspek konten dan pedagogi, (6) revisi script dan storyboard, (7) pembuatan multimedia yang kemudian di validasi pada aspek multimedia. Multimedia ini kemudian ditanggapi oleh guru dan siswa untuk mengetahui kualitas multimedia berdasarkan kriteria/ indikator yang telah ditentukan melalui angket. Hasilnya diolah secara deskriptif persentase. Angket diberikan kepada lima orang guru mata pelajaran Kimia dan 30 orang siswa SMA kelas XI dan XII yang telah mempelajari mengenai sub-konsep konfigurasi elektron berdasarkan model atom Bohr yang diperluas. Berdasarkan data angket guru diperoleh hasil bahwa tingkat persetujuan terhadap: (1) kualitas multimedia adalah 84%, (2) kejelasan penyampaian materi/ konsep adalah 96%, (3) peran multimedia adalah 100%, dan (4) pengembangan multimedia adalah 100%. Secara keseluruhan respon guru terhadap multimedia terletak pada daerah positif. Berdasarkan data angket siswa diperoleh hasil bahwa tingkat persetujuan terhadap: (1) motivasi pada multimedia adalah 85.31%, (2) konten pada multimedia adalah 84.7%, (3) navigasi pada multimedia adalah 86%, (4) multimedia dan interaktivitasnya adalah 90.84%, dan (5) tampilan multimedia adalah 86.77%. Secara keseluruhan respon siswa terhadap multimedia terletak pada daerah setuju. Dengan demikian representasi kimia sekolah berbasis intertekstual pada sub-konsep konfigurasi elektron model atom Bohr yang diperluas dalam bentuk multimedia yang telah dikembangkan dapat digunakan.ABSTRACTHas done research that results in the form of textual representations of chemical-based multimedia sub-concept of electron configurations based on the extended Bohr model of the atom. This study used a descriptive and evaluative methods that are part of the Research and Development (R D). Procedure of the research work carried out in several stages, namely: (1) determination of the subject matter, (2) a standard assessment and basic competencies contained in content standards and sample syllabi BSNP to define indicators and concepts, (3) existing multimedia collection, (4 ) analysis of existing multimedia based study aspects of content, pedagogy, and multimedia, (5) creation scripts and storyboards are validated based on aspects of content and pedagogy, (6) the revised script and storyboard, (7) multimedia creation later in the validation of the multimedia aspect. Multimedia is then taken up by teachers and students to determine the quality of multimedia based on the criteria / indicators that have been determined through a questionnaire. The results are processed by descriptive percentages. Questionnaires given to five teachers of Chemistry subjects and 30 high school students of class XI and XII who have studied the concept of sub-electron configuration by the extended Bohr model of the atom. Based on data from the teacher questionnaire obtained results that the level of agreement to: (1) multimedia quality is 84%, (2) clarity of delivery of materials / concepts was 96%, (3) the role of multimedia is 100%, and (4) development of multimedia is 100% . Overall the response of teachers to the multimedia lies in the positive region. Based on data from student questionnaires obtained results that the level of agreement to: (1) multimedia motivation is 85.31%, (2) the contents of multimedia is 84.7%, (3) navigation in multimedia is 86%, (4) multimedia and interaktivitasnya is 90.84% and (5) multimedia display is 86.77%. Overall the students' response to the multimedia lies in the area agreed. Thus the textual representation of chemical-based schools in the sub-concepts of the Bohr model of the atom the electron configurations are expanded in the form of multimedia that has been developed can be used.

Student conceptions provide valuable information for understanding learning difficulties and provide insight into how they can be addressed appropriately. Analyzing students' conceptions can also provide insight into what concepts are troublesome or serve as concepts affecting learning. Using the Interview About Event-Mental Model Diagnostic Test (TDM-IAE), twenty-one high school and university students' conceptions, troublesome knowledge, and threshold concepts for understanding the effect of catalyst to reaction rate were identified. Students mostly held partial mental models or mental models with misconceptions in which three concepts were considered troublesome and threshold concepts for understanding the effect of catalyst on reaction rate.

The implementation of games in chemistry classes has provided an interesting and alternative teaching method and allows students to learn in a more entertaining way compared to traditional learning process. The game-based learning approach is divided into three approaches, namely game-based learning or educational games, gamification, and game-assisted learning. Many chemistry games have been constructed in recent years to review and strengthen various chemistry topics; therefore, it is expected that Chemistry teachers in high schools in Indonesia, especially in West Java province implement educational games in the learning process. For that reason, it is necessary to perceive an overview of the use of educational games in Chemistry learning in secondary schools in West Java province. Survey research was carried out using a random sampling technique. There were 99 chemistry teachers from 91 high schools spread across the province of West Java who voluntarily participated in the online survey. The result of the analysis obtained that 35% of chemistry teachers in the province of West Java have implemented gamification and learning using game assistance. On the contrary, game-based learning has never been implemented in Chemistry learning process in secondary schools in West Java province

This study aims to analyze students' mental models on the concept of chemical bonds using a two-tier mental model diagnostic test. A test with the first tier asking the content and the second tier asking the reasons for the answers at the first tier. The test used has been developed and declared valid with a degree of reliability 0.751. This research is qualitative research with a case study design. Students' mental models are categorized into complete mental models, partial mental models, mental models with misconceptions, and mental models with inconsistencies. In the concept of chemical bonds found 17, 9, 15, and 59% of students with complete, partial, misconceptions, and inconsistencies in mental models respectively. Most students have misconceptions by stating that ionic bonds are formed through atomization and the formation of bonding electrons by reason of the sharing of electrons in ionic crystals. In addition, students understand that the process of forming covalent bonds in oxygen and fluorine occurs because of the attraction between atoms which is greater than the repulsion between bonded atoms. Among the inconsistent concepts found are students explaining the phenomenon of solubility, boiling point, and melting point based on the concept of the electron cloud.
