“…The use of concrete media is considered to be no longer relevant to the times that demand a clearer, wider, and faster visualization of three-dimensional objects. (Al-Balushi & Coll, 2013;Anggriawan, effendy, & Budiasih, 2017;Antonoglou et al, 2011;Barrett et al, 2015;Cass, Rzepa, Rzepa, & Williams, 2005;Charistos, Tsipis, & Sigalas, 2005;Mohamed-Salah & Alain, 2016;Stull & Hegarty, 2016;Tuvi-Arad & Gorsky, 2007). Virtual media can cover many shortcomings of concrete media.…”

“…Third, building a representation or visualization of three-dimensional objects in space with good quality is essential (Harle & Towns, 2011). Fourth, manipulating representative three-dimensional objects in space should also be done (Tuvi-Arad & Gorsky, 2007). Students with low visuo-spatial and representational competence thinking skills will have difficulty identifying them.…”

“…The boundless interactions offered by the concrete media cause positional errors after rotation and reflection. In contrast, virtual media with limited interaction uses the object movement simulation feature appropriately so that there will be no errors in identifying the symmetry operation Sn (Anggriawan et al, 2017;Antonoglou et al, 2011;Cass et al, 2005;Tuvi-Arad & Gorsky, 2007). Based on this case, it can be assumed that the use of virtual media is superior to concrete media in identifying rotational symmetry operations through the pseudo-axis of rotation.…”

mastering the topic of symmetry requires a good representational competence to smoothly understand, visualize, and manipulate the movement of three-dimensional objects. This literature study aimed to describe how concrete and virtual media can be utilized in improving students' understanding of the topic. The study implies that the thinking process, cognitive tasks, interactions, mental models, and the completeness features displayed by the two models in identifying all symmetrical operations are the distinguishing factors of the effectiveness of the two formats in affecting students' understanding. The study also implies that the virtual format will contribute to students' understanding better than the concrete format does. However, the empirical study must be explored further to ensure the difference between the two formats.

“…Of its many features it is worth mentioning the ability to animate conformational change (resulting, e. g., from conformation analysis or molecular dynamical simulation) and molecular vibrations, to present point group symmetry elements as well as various crystallographic views, and a wealth of coloring schemes for displaying proteins and their building blocks. Several applications of using Jmol for educational purposes have been published . Jmol is used by many chemistry‐related websites (many are listed here: http://wiki.jmol.org/index.php/Websites_Using_Jmol) and compound databases, e. g., ChemSpider, the Protein Data Bank, and the Crystallography Open Database described in Section 3.5.…”

The chemical sciences integrate numerous pieces of structural data into families of compounds, and countless experimental results of reactive processes into ground rules. Collecting these pieces of information, analyzing them, and making the relevant contextual connections between them is in the heart of chemistry education. Here we emphasize the contribution of technology, and more specifically, chemical databases for enhancing these learning processes. Several important, open access, databases are described in detail and examples of using them in chemistry class are provided.In an era of continuous information revolution we hope that chemistry instructors will take the next step up, and acquire the professional skills needed to integrate the use of technology and chemistry databases in their classes.

“…Program komputer bersifat dinamis, dapat menampilkan struktur molekul di layar menjadi lebih "terlihat" dan "berperilaku" seperti "molekul nyata" (Hahre, Nelson & Shusterman, 1998). Dampak pembelajaran menggunakan program komputer pun telah banyak dilaporkan peneliti diantaranya dapat membantu siswa mengatasi kesulitan memahamistruktur dan eleman simetri molekul kompleks (Tuvi-Arad & Gorsky, 2007), alat bantu efektif untuk pengajaran stereokimia (Abraham, et al, 2010), meningkatkan skor post test secara signifikan pada topik terkait sudut ikatan, sifatsifat 3D molekul seperti kiralitas dan konformasi (Springer, 2014).…”

Abstrak: Penelitian ini bertujuan menyelidiki keefektifan program pembelajaran stereokimia berbasis visualisasi 3D molekul menggunakan salah satu chemical drawing software berbasis open source, yakni Avogadro dan animasi kekiralan melalui komputer untuk meningkatkan kemampuan spasial mahasiswa calon guru. Studi menggunakan quasi experimental control group pretest-posttest design. Instrumen penelitian terdiri atas 25 soal pilihan ganda disertai alasan yang disusun berdasarkan indikator tiga dimensi utama kemampuan spasial. Subjek penelitian terdiri atas kelas kontrol dan kelas eksperimen, masingmasing ada sebanyak 30 mahasiswa. Teknik pengumpulan data dilakukan dengan tes, sedang analisis data dilakukan dengan teknik statistik dengan bantuan SPSS versi 17. Hasil penelitian menunjukkan bahwa rata-rata skor post test kemampuan spasial kelompok mahasiswa dengan pembelajaran stereokimia berbasis visualisasi 3D molekul secara signifikan lebih tinggi dibandingkan kelompok mahasiswa yang media pembelajarannya menggunakan molymod. Keefektifan program ditunjukkan oleh peningkatan N-gain dalam kategori sedang dan efek size (d) dalam kategori tinggi untuk ketiga dimensi utama kemampuan spasial. Kata kunci: stereokimia, visualisasi 3D, kemampuan spasial, software open-source THE EFFECTIVENESS OF STEREOCHEMISTRY BASED ON 3D VISUALIZATION OF MOLECULES IN IMPROVING SPATIAL ABILITYAbstract: The purpose of this study is to investigate the effectiveness of stereochemistry learning programs based on 3D visualization of molecules using open source chemical drawing software, Avogadro, and animation of chirality to improve spatial ability of prospective teachers. This study used a quasiexperimental control group pre test-post test design. The research instrument consisted of 25 multiple choice questions along with the reasons elaboration, composed based on three major indicator dimensions of spatial ability. The research was conducted at a LPTK in Lampung Province, in the first semester of Academic Year 2014/2015. The subjects consisted of control class and experimental class, each of which consisted of 30 students. The results showed that the average post test score of spatial ability of students learning stereochemistry based on 3D visualization of molecules was significantly higher than those of the group of students learning using molymod media. The effectiveness of the program was shown by the increase in N-gain in the medium category and effect size (d) in high category for the three main dimensions of spatial ability.
