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.

Reaction rate is still considered difficult by students because it contains abstract concepts and mathematical equations, so students' mental models are not complete. To connect the three levels of representation in the process of addressing chemical problems, learning has to employ mental models as a whole. Therefore, this study aims to obtain students' mental models regarding the influence of reactants properties on reaction rates. This research uses a qualitative descriptive method with the Mental Model Diagnostic Test-Interview About Event (MMDT-IAE) instrument. Based on the research results, there are two types of mental models, namely Partial Understanding (PU) and Partial Understanding with Certain Misconceptions (PU/SM). The effect of surface area on reaction rate, students 1, 2, 3, 4, 6, and 7 answered correctly but could not connect the three levels of representation, while student 5 could not explain the relationship between effective collisions and reaction rate. The influence of structure on reaction rates, students 1, 2, 3, 4, and 7 can answer structure, reactivity and collision theory, while student 5 cannot explain collision theory. Students 1, 4, and 7 can answer all the probing questions but cannot connect the three levels to the influence of ionization energy on the reaction rate. The conclusion of this research is that students' mental models regarding the influence of reactant properties are not complete and there are students who experience misconceptions. The implications of this research are as a basis for teachers to design appropriate learning strategies.Keywords: Mental model; MMDT-IAE; Reaction rate; Three level of representation

The aim of this study is to identify how the POE learning integrated into D-GBL can construct student’s mental models on temperature effect on reaction rate and the game design is created. This research is a part of the Research and Development (R&D) with Borg and Gall model. This study is focused on the third stage. The study began with collecting information, planning product, and prototype development. For product design, the study created mission and sub-missions to represent the POE steps, which are predicting, observing, and explaining. The information was collected from various literature reviews on D-GBL and mental model. For product design, mission and sub-missions were created to represent POE steps. Next, the prototype was developed in the form of a game design document. Students must answer various questions to complete these missions and sub-missions. If the answers are given incorrect, the game restart from the beginning of that mission. Therefore, D-GBL integrated in the POE model can construct students' mental models.

Tujuan penelitian ini adalah memperoleh profil model metal siswa padakonsep dasar laju reaksi. Partisipan penelitian ini adalah tujuh orang siswakelas XII IPA di salah satu SMA Negeri di Kota Bandung dengan tigakemampuan akademik yang berbeda, yaitu tinggi, sedang, dan rendah.Metode yang digunakan adalah kualitatif dengan analisis deskriptifmenggunakan instrumen penelitian Tes Diagnostik Model Mental Inteview-About-Event (IAE). Berdasarkan hasil penelitian ditemukan bahwa siswakemampuan sedang dan rendah menjawab benar sebagian setalah diberipertanyaan probing dalam menjelaskan perubahan laju rerata penguranganreaktan dan laju rerata pembentukan produk, sedangkan siswa kemampuantinggi menjawab salah walaupun telah diberi pertanyaan probing. Dalammenjelaskan laju rerata pembentukan produk banyak siswa yang mengalamimiskonsepsi bahwa laju rerata pembentukan produk meningkat karenajumlah partikelnya meningkat. Dalam menjelaskan laju sesaat pada waktutertentu dan waktu pada nol pada umumnya ditemukan bahwa siswakemampuan tinggi, sedang, dan rendah blank, tidak dapat menjawabapapun mengenai laju sesaat meskipun sudah diberi pertanyaan probing.Dalam menjelaskan laju reaksi terdapat siswa kemampuan tinggi dansedang yang menjawab benar dengan pertanyaan probing ketikamembandingkan laju salah satu spesi untuk mencari spesi lainnya, tetapitidak ada yang menjawab benar dalam menghubungkan laju reaksi, lajupengurangan reaktan, dan laju pembentukan produk.

This article examines organic chemistry educational games developed between 2017-2023. The purpose of this study is to find out the types of educational games that are most developed, organic chemistry materials that have been developed in the form of educational games, and the positive impact of educational games in studying organic chemistry. The method used in this study is a systematic literature review. The systematic literature review is carried out in three stages, namely the planning stage, the implementation stage, and the reporting stage. Based on the results of the study, 38 articles were obtained by the criteria and further analysis was carried out. The results of the analysis show that organic chemistry educational games are developed with various types of games both in digital and non-digital forms. The most developed organic chemistry educational games are strategy video games and card games. The most developed material in the form of educational games is the molecular structure of organic compounds which is shown to deepen students' understanding in organic chemistry courses.

Intertextuality refers to the process of understanding a context by exploring and connecting relationships between different texts or representations. In chemistry education, intertextuality serves as a communication bridge that links the three levels of chemical representation: macroscopic, submicroscopic, and symbolic. This study aims to enhance students' understanding of Molecular Geometry Concepts through Intertextual-based Learning with 3D- visualization. The research employed a quantitative approach with a one-group pretest-posttest design. Participants were selected using purposive sampling from undergraduate chemistry education students. The study involved 26 first-year students majoring in chemistry education who were taking a general chemistry course. Data were collected using student worksheets and pretest-posttest assessments. The data analysis included t-paired test for parametric statistic and evaluating student responses related to learning outcomes. Analysis of the t-paired test results shows that there is a significant difference in the pretest and posttest scores with a significance value of (p> α0.05). The most influenced concept indicator in this study was the concept of molecular geometry types with an increase of 57% in students’ correct answers. Keywords: student’s understanding, molecular geometry, intertextual based learning, 3d visualization, undergraduate students. DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1468-1479
