Abstract

Tujuan penelitian ini untuk mengetahui keefektifan pembelajaran Computer Assisted Instruction (CAI) Berbantuan Software GeoGebra  terhadap kemampuan spasial dan kemampuan komunikasi matematis siswa pada materi transformasi Geometri. Populasi dalam penelitian ini adalah siswa kelas XI SMKN 3 Kuningan tahun pelajaran 2013/2014. Pemilihan sampel dengan cara purposed random sampling, pada pemilihan sampel diperoleh siswa XI-TSM 2 sebagai kelas eksperimen dan kelas XI-TSM 4 sebagai kelas kontrol. Kelas eksperimen diajar dengan pembelajaran Computer Assisted Instruction (CAI) Berbantuan Software GeoGebra, sedangkan kelas kontrol diajar dengan pembelajaran ekspositori. Pengambilan data diperoleh dengan hasil pretest dan postest untuk mendapatkan data nilai kemampuan spasial dan kemampuan komunikasi matematis siswa yang kemudian dianalisis dengan uji perbedaan rata-rata. Hasil penelitian adalah (1) Peningkatan kemampuan spasial siswa kelas eksperimen lebih baik daripada kelas kontrol. (2) Peningkatan kemampuan komunikasi matematis siswa kelas eksperimen lebih baik daripada kelas kontrol. (3) Terdapat korelasi yang positif antara kemampuan spasial dan kemampuan komunikasi matematis.   The purpose of this study to determine the effectiveness of study Computer Assisted Instruction (CAI) aided software GeoGebra on spatial ability and mathematical communication skills of students in the material transformation of Geometry. The population in this study is class XI student of SMKN 3 Kuningan in the academic year 2014/2015. Election purposed sample by random sampling, sample obtained by the students XI-2 as the experimental class TSM and TSM class XI-4 as the control class. Experimental class taught by CAI aided Software GeoGebra, while the control class was taught by expository. Data obtained with the results of the pretest and posttest then analyzed with the average difference. The results are:(1) Improvement of spatial ability students experimental class is better than the control class.(2)The increase in students' mathematical communication skills experimental class is better than the control class.(3)There is a positive correlation between spatial ability and mathematical communication skills.

GeoGebra软件辅助数学学习提高SMK学生的空间能力和数学交流能力
本研究的目的是针对学生在几何变换材料中的空间和数学交流能力,确定使用GeoGebra软件进行计算机辅助教学(CAI)学习的有效性。本研究中的人群为2013/2014学年XI SMKN班3年级学生。通过有目的的随机抽样进行样本选择,在样本选择时,获得XI-TSM 2学生作为实验班,XI-TSM 4学生作为对照班。实验课采用GeoGebra软件的计算机辅助教学(CAI),而控制课采用暴露学习。数据检索是通过前测和后测结果获得的,以获得空间能力和数学交流能力的数据值,然后用平均差分测试对学生进行分析。研究结果表明:(1)实验班学生的空间能力的提高优于对照班。(2) 在实验课上提高数学学生的交流能力比在对照课上要好。(3) 空间与数学交流之间存在着正相关关系。[UNK]本研究的目的是确定计算机辅助教学(CAI)辅助软件GeoGebra对学生在几何材料转换中的空间能力和数学交流技能的有效性。本研究对象为2014/2015学年SMKN 3 Kuningan XI班学生。以随机抽样的方式选取有针对性的样本,样本由学生XI-2作为实验班TSM,学生XI-4作为对照班。实验课采用计算机辅助教学软件GeoGebra,控制课采用说明文教学。用前测和后测的结果获得的数据,然后用平均差进行分析。结果表明:(1)实验班学生空间能力的提高优于对照班。(2) 实验班学生数学交际能力的提高优于对照班。(3) 空间能力与数学交流能力之间存在正相关关系。
