International Electronic Journal of Mathematics Education

The purpose of this study is to examine those factors that affect the geometry problem solving (GPS) abilities of the students. This study involved 101 Indonesian high school students. They were divided into two groups based on the implemented LA, namely the investigative learning group and the direct instruction group. Data were collected through three instrument types, namely test of BGC, GPS, and MSE. The MSE scale consists of two models namely mathematics test-taking self-efficacy (MTSE) and mathematical skill self-efficacy (MSSE). Data were analyzed using ANOVA techniques, path analysis, and error analysis. The path diagram is MSE, which mediates the BGC effect on GPS. Data analysis results revealed that the level of BGC, MTSE as well as interactions between LA and gender had a significant impact on the GPS capability of students. In this case, the BGC of the students impacted their MSE and thus impaired their GPS skills, which also moderated the gender and learning. There are phases in the process of solving problems that tend to hamper student performance. The visualization process appears to be done by female students, while male students make representations when they do. The researchers, therefore, suggest further research related to gender-based LA study in the geometry curriculum to improve the ability of the students.

As for the stages carried out include: 1) conducting a literature study to get indicators of mathematical imagination ability, 2) preparing instruments based on the indicators obtained, and 3) testing the validity and readability test of the instruments that have been prepared. The readability test was conducted by 30 junior high students, while the validity test was conducted by 6 experts consisting of 2 learning experts in junior high school, 2 learning evaluation experts, and 2 mathematics education experts. Readability test results state that of the 12 items created, 6 questions can be understood by students, while the other 6 questions cannot be understood by students. Furthermore, 6 questions that can be understood by students were tested for validity. The test results show that 3 items are declared valid without revision, 3 items are declared to need revision. There is 1 item that needs to be revised answer key. The validator also provides suggestions to sort the questions from the easiest to the most difficult questions.

By using realist ethnography, this study reports objectively the information that collected from participant in the Cigugur traditional communitythrough observation, interviews, documentation, and field notes. The findings from this study show that the farming system carried out by the community used formal mathematics principles. The hari cycle and pasaran cycle in Sundanese are as the same as the concept of relations and functions in mathematics. The function in question is injective function. The results of the relations between day "hari" and "pasaran" can be expressed in an order pair to pair. To determine a finest day, the mathematical concepts used by the Cigugur traditional community are the concepts of addition and the concept of comparison. The sum concept is used to add the values of each day to the value of each pasaran. Meanwhile, the concept of comparison is used to compare the value of the sum results with the criteria for determining the finest day for tandur. Ethnomatematics provides different perspectives regarding mathematical conceptuality.

Selain itu matematika juga berperan besar dalam perkembangan teknologi informasi dan komunikasi yang kian pesat. Untuk menguasai dan mencipta teknologi di masa depan diperlukan penguasaan matematika yang kuat sejak dini. Siswa diharapkan memiliki berbagai kemampuan agar kualitas pembelajaran matematika lebih baik. Tujuan pembelajaran matematika di sekolah menurut Permendiknas No. 22 (Depdiknas, 2006, hlm. 346) adalah: (1) Memahami konsep matematika, menjelaskan keterkaitan antarkonsep dan mengaplikasikan konsep atau algoritma, secara luwes, akurat, efisien, dan tepat, dalam pemecahan masalah, (2) Menggunakan penalaran pada pola dan sifat, melakukan manipulasi matematika dalam membuat generalisasi, menyusun bukti, atau menjelaskan gagasan dan pernyataan matematika, (3) Memecahkan masalah yang meliputi kemampuan memahami masalah, merancang model matematika, menyelesaikan model dan menafsirkan solusi yang diperoleh, (4) Mengomunikasikan gagasan

Penelitian ini merupakan penelitian quasi experiment dengan desain kelompok kontrol non ekivalen. Populasi pada penelitian ini adalah seluruh siswa kelas V pada dua kecamatan di kabupaten Subang, Sample penelitian pada penelitian ini adalah seluruh siswa kelas V salah satu sekolah dasar di Kecamatan Subang Kabupaten Subang dan salah satu sekolah dasar yang terletak di Kecamatan Jalancagak Kabupaten Subang. Instrumen yang digunakan berupa instrumen tes, analisis kuantitatif dilakukan terhadap rata-rata pretes dan postes dengan menggunakan Uji-t. Berdasarkan pada hasil penelitian, menunjukan bahwa data pretes tidak terdapat perbedaan kemampuan koneksi matematis antara siswa yang memperoleh pembelajaran dengan model pembelajaran Problem Based Learning berbantuan TIK dan siswa yang memperoleh pembelajaran dengan model direct teaching. Diketahui pula bahwa pada hasil analissi data posttes, kemampuan koneksi matematis siswa yang memperoleh pembelajaran dengan model pembelajaran Problem Based Learning berbantuan TIK lebih baik daripada siswa yang memperoleh pembelajaran dengan model direct teaching. Dengan demikian disimpulkan bahwa model pembelajaran Problem Based Learning berbantuan TIK memberikan pengaruh yang positif terhadap kemampuan koneksi matematis siswa. Pembelajaran dengan model Problem Based Learning berbantuan TIK dapat menjadi alternatif model pendekatan pembelajaran yang dapat digunakan di Sekolah Dasar.
