Abstract: Penelitian ini bertujuan untuk menyelidiki faktor-faktor yang menyebabkan kesulitan mahasiswa STKIP BBG dalam mempelajari geometri dimensi tiga. Penelitian ini menggunakan metode penelitian kualitatif studi kasus untuk mengkaji proses pembelajaran mahasiswa calon guru matematika di lingkungan STKIP BBG. Subjek dalam penelitian ini adalah 16 orang mahasiswa calon guru matematika STKIP BBG Semester II-IV Tahun Akademik 2016/2017 yang dipilih secara purposive s ling. Pengumpulan data dilakukan dengan menggunakan tehnik angket, tes, dan wawancara. Hasil penelitian menunjukkan bahwa kedua faktor internal dan ekternal memberi pengaruh terhadap kesulitan belajar yang dialami oleh mahasiswa pendidikan matematika STKIP BBG. Faktor internal sebagai penyebab kesulitan adalah faktor minat, bakat dan intelegensi mahasiswa yang memiliki persentase lebih dari 50% tergolong rendah dan sangat rendah. Adapun faktor ekternal, diantaranya adalah aspek penggunaan metode mengajar oleh dosen dimana, peny aian materi oleh dosen tanpa menyesuaikan kem uan mahasiswa memiliki peran yang tinggi (68.75%) dalam memunculkan kesulitan terhadap penguasaan konsep-konsep geometri dimensi tiga. Selain itu, pengalaman belajar geometri pada jenjang sekolah sebelumnya juga menjadi faktor lain yang mengakibatkan kesulitan belajar geometri dalam penelitian ini. The cause of difficulty in learning the three-dimensional geometry AbstractThis study aims to investigate the factors that cause STKIP BBG’s prospective teachers difficulties in learning three-dimensional geometry. This research uses a case study qualitative research method to assess student learning process of prospective mathematics teachers in mathematics department at STKIP BBG. Subjects in this study were 16 prospective mathematics teachers in semester II - IV academic year 2016/2017 at STKIP BBG. The subjects were selected by purposive s ling. Data collection was done by using questionnaire technique, tests and interviews. The results showed that both internal and external factors had given effects toward learning difficulties experienced by mathematics education students at STKIP BBG. The internal factors are which suspected as the difficulty’s cause are the interest factor talent and intelligence where 50% of prospective mathematics teachers are in low and very low level. Meanwhile, the external factors, such as the use of teaching methods by lecturers where, the delivery of materials by lecturers without adjusting the ability of students have a high role (68.75%) in raising difficulties on the mastery of three-dimensional geometry concepts. In addition, the experience of learning geometry at the previous school level is also another factor that leads to difficulties in learning geometry in this study.

Analyzing Second-Year University Students’ Rational Number Understanding: A Case on Interpreting and Representing Fraction

DOI: 10.12973/EU-JER.11.3.1747
Abstract: style="text-align:justify" This research aims to determine second-year university students’ understanding in interpreting and representing fractions. A set of fraction tests was given to students through two direct learning interventions. An unstructured interview was used as an instrument to obtain explanations and confirmations from the purposive participants. A total of 112 student teachers of primary teacher education program at two private universities in Indonesia were involved in this research. A qualitative method with a holistic type case study design was used in this research. The results indicate that a significant percentage of the participants could not correctly interpret and represent fractions. In terms of interpretation, it is found how language could obscure the misunderstanding of fractions. Then, the idea of a fraction as part of a whole is the most widely used in giving meaning to a fraction compared to the other four interpretations, but with limited understanding. Regarding data representation, many participants failed to provide a meaningful illustration showing the improper fraction and mix number compared to the proper fraction. Improvement of fraction teaching at universities - particularly in primary teacher education programs - is needed so that students get the opportunity to develop and improve their knowledge profoundly. We discuss implications for teaching fractions.
