Abstract

Abstrak: Penelitian ini berdasarkan pada teori belajar konstruktivis secara individual dan sosial. Tujuan utama penelitian adalah menyelidiki efektifitas metode kolaboratif dan belajar individual secara tradisional dalam mengembangkan keterampilan pemecahan masalah kimia secara matematis. Perbandingan kedua metode belajar menggunakan desain quasi eksperimen. Subjek penelitian terdiri atas 60 mahasiswa kimia yang sedang memprogramkan mata kuliah matematika kimia. Hasil analisis data mengindikasikan bahwa efektifitas kedua metode belajar dipengaruhi oleh jenis materi kimia yang dipelajari dan konsep matematika yang relevan. Kemampuan pemecahan masalah mahasiswa yang belajar individual lebih baik dibandingkan dengan belajar kolaboratif pada materi kinetika yang menggunakan konsep kalkulus. Akan tetapi, kedua lingkungan belajar memberikan pengaruh yang sama pada kemampuan pemecahan masalah kimia menggunakan konsep dasar matematika seperti logaritma dan aljabar. Selain pendekatan belajar, kemampuan mahasiswa kimia dalam pemecahan masalah dipengaruhi oleh sejumlah faktor meliputi: faktor kognitif dan pengalaman belajar. Temuan penelitian ini dapat memberikan konstribusi pada pemilihan strategi belajar dengan mempertimbangan sejumlah faktor yang berpengaruh. Kata Kunci: pendidikan kimia, mahasiswa, belajar kolaboratif dan individual, pemecahan masalah, materi matematika A COMPARISON OF THE COLLABORATION METHOD USING THE TASK SAMPLE AND INDIVIDUAL LEARNING IN THE DEVELOPMENT OF CHEMISTRY PROBLEM SOLVING SKILLS Abstract: This study was based on the individual and social constuctivist learning theory. This study was aimed to examine the effectiveness of the collaborative learning and traditional individual learning to improve the students’ problem solving skills. This study used the quasi-experimental design. The subjects were 60 Chemistry students enrolling the Chemistry Mathematics course. The findings showed that the effectiveness of both methods was influenced by the type of the chemistry materials being studied and relevant mathematical concepts. The problem solving skills of the students learning individually was better than those of the students learning collaboratively in the kinetics concept using the calculus concept. However, both learning settings gave the same influence on the chemistry problem solving skills using the basic mathematics concepts such as logarithma and algebra. In addition to the learning approach, the students’ problem solving skills were also influenced by several factors including: cognitive and learning experience factors, These findings can give contribution to the choice of learning strategies by taking into account of the influential factors.

Abstract

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 dari 25 soal pilihan ganda disertai alasan, disusun berdasarkan indikator tiga dimensi utama  kemampuan spasial. Penelitian dilaksanakan di satu LPTK di Provinsi Lampung,  semester ganjil Th. Akademik 2014/2015. Subjek penelitian terdiri dari kelas kontrol dan kelas eksperimen, masing-masing ada sebanyak 30 mahasiswa.  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 ABILITY Abstract: The purpose of this study is to investigate the effectiveness of stereochemistry learning programs based on 3D visualization of molecules using the open source chemical drawing softwares, Avogadro, and animation of chirality to improve spatial ability of teacher candidates. This study used a quasi-experimental control group pretest-posttest 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 scores of spatial ability of students learning stereochemistry based on 3D visualization of molecules was significantly higher than the group of students learning using molymood 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. Key words: stereochemistry, 3D visualization, spatial ability, open-source software
