Based on TIMSS 2011 and PISA 2018, mathematical connection ability of Indonesian students has not been optimal. Some of questions in TIMSS and PISA measured the mathematical connections ability. Needed the instructional media to increase mathematical connection ability, such as puzzle and GeoGebra. In addition, gender also affects students' mathematical ability. This study aims to investigate differences in mathematical connection abilities between students who learning by puzzle and GeoGebra, investigate differences in mathematical connection abilities between male and female students, and investigate interactions between instructional media and gender. This research was a quasi-experiment which used nonequivalent control group design. The samples were students of class VIII-A and VIII-B in Junior High School of 1 Tangerang City. The instruments in this research consisted of test items, such as pretest and posttest. Hypotheses test through parametric test (ANOVA Two Tail). Based on ANOVA Two Tail-test result, showed that there is difference increase in mathematical connection ability students who learning by GeoGebra and puzzle. Then, there is no difference increase mathematical connections ability between male and female students. The factors of instructional media and gender do not equally affect the increase of mathematical connection ability.

Penelitian tindakan kelas ini bertujuan untuk meningkatkan hasil belajar matematika siswa kelas XII IPA 9 SMA Negeri 1 Palembang melalui pembelajaran berbantuan GeoGebra. Subjek dalam penelitian ini terdiri dari 29 orang siswa. Materi yang diajarkan dalam penelitian ini adalah nilai maksimum dan minimum, selang kemonotonan, gradien garis singgung, dan selang kecekungan kurva fungsi trigonometri. Siklus pertama dilaksanakan sebanyak tiga pertemuan dan siklus ke-2 sebanyak dua pertemuan. Instrumen yang digunakan adalah tes hasil belajar dan observasi. Tes hasil belajar digunakan untuk mengetahui capaian siswa pada setiap siklus dan observasi digunakan untuk mengumpulkan data selama proses pembelajaran berlangsung. Data dianalisis secara kuantitatif dan deskriptif. Hasil penelitian menunjukkan bahwa nilai rata-rata siswa kelas XII IPA 9 pada tes siklus pertama adalah 50,00 dan pada tes siklus ke-2 sebesar 82,76. Hasil penelitian menunjukkan bahwa pembelajaran berbantuan GeoGebra dapat meningkatkan hasil belajar matematika siswa, yaitu sebesar 80% siswa telah mencapai ketuntasan pada siklus kedua.
