AbstractOne of the factors causing the low score of student learning outcomes Statistics and Probability on midterm exams is that during practice or studying on their own, students feel the complexity of solving questions about data analysis in Statistics and Probability courses and the difficulty of obtaining confirmation of correct answers. This encourages to find alternative solutions. One of them is using Excel and Statistical Program of Social Science (SPSS) software in Statistics and Probability learning. The purpose of this research is to improve the learning outcomes of Statistics and Probability using Excel and SPSS software. The method used in this research is the One-Group Pretest-Posttest Design. Samples were selected using the Cluster Random Sampling technique. To see if there is an increase in learning outcomes, it is done by comparing the average learning outcomes of the midterm exams (before using Excel and SPSS software) and final semester exams (after using Excel and SPSS software). The results of the Wicoxon test showed Asymp. Sig. (2-tailed) 0.000 less than 0.05, so it can be concluded that the pretest and posttest means are significantly different. This shows that there is an increase in learning outcomes before and after learning using Excel and SPSS software, so it is concluded that student learning outcomes in Statistics and Probability courses can be improved through learning by using Excel and SPSS software. Keywords: excel; learning outcomes; software; SPSS Abstrak Salah satu faktor penyebab rendahnya nilai hasil belajar Statistik dan Probabilitas mahasiswa pada ujian tengah semester disebabkan pada saat latihan atau belajar sendiri. Mahasiswa merasakan rumitnya penyelesaian soal tentang analisis data pada mata kuliah Statistik dan Probabilitas dan sulitnya memperoleh konfirmasi jawaban benar. Hal ini mendorong untuk menemukan alternatif solusi. Salah satu alternative solusi adalah memanfaatkan software Excel dan Statistical Program of Social Science(SPSS) dalam pembelajaran Statistik dan Probabilitas.Tujuan penelitian ini adalah untuk meningkatkan hasil belajar Statistik dan Probabilitas menggunakan software Excel dan SPSS. Metode yang digunakan dalam penelitian ini adalah One-Group Pretest-Posttest Design. Sampel dipilih dengan teknik Cluster random Sampling. Untuk melihat apakah ada peningkatan hasil belajar, dilakukan dengan membandingkan rata-rata hasil belajar ujian tengah semester (sebelum memanfaatkan software Excel dan SPSS) dan ujian akhir semester (setelah memanfaatkan software Excel dan SPSS). Hasil uji Wicoxon menunjukkan Asymp. Sig. (2-tailed) 0,000 kurang dari 0,05 sehingga disimpulkan bahwa rata-rata pretest dan posttest berbeda  secara signifikan. Hal ini menunjukkan bahwa terjadi peningkatan hasil belajar sebelum dan sesudah pembelajaran memanfaatkan software Excel dan SPSS, sehingga disimpulkan bahwa hasil belajar mahasiswa pada mata kuliah Statistik dan Probabilitas dapat ditingkatkan melalui pembelajaran dengan memanfaatkan software Excel dan SPSS.Kata kunci: excel; hasil belajar; software; SPSS.

This research aimed to determine the effect of STAD cooperative learning model to student learning outcomes in the subject matter of fluid at class XI IPA SMA Negeri 1 Padangsidimpuan. This was eksperimental research with One Group Pretest Posttest Design. The population was all class XI IPA SMA Negeri 1 Padangsidimpuan (128 students) and sample was taken through cluster random sampling, so the sample was 32 students. The instrument of this research was the achievement test. The result of this study indicated that student learning outcomes using STAD cooperative learning model (74,69) were higher than student learning outcomes using convensional learning model (62,25). Based on the  result of hypothesis testing at significance level 5% with degree of freedom 31, tcount = 9,79 > ttable = 1,698 then the hypothesis can be accepted, it means that there was influence STAD cooperative learning model to student learning outcomes in the subject matter of fluid at class XI IPA SMA Negeri 1 Padangsidimpuan.

This research is a quantitative research.. The research method used is quasy experiment with the matching only pretest-posttest control group design research design. The population in this study were all Grade V Bengkulu City Vocational Schools that had used the 2013 curriculum and were accredited A. The sample in this study were VA grade students in 82 State Primary Schools in Bengkulu City and VC Grade Students in 61 Primary Schools in Bengkulu City with 64 students person. The sampling technique uses cluster random sampling, namely multistages cluster random sampling. The instrument used in the study was a test of learning outcomes in the form of multiple choice questions through pretest and posttest, the results of learning the attitude and skills aspects of the instrument used were observation sheets. To measure aspects of the knowledge of taking the test twice, namely before and after learning takes place in the experimental and control classes. Data analysis technique in this research is quantitative analysis using descriptive statistics and inferential statistics. From the research results it is known that the results of the t-test for Indonesian subjects t-test was 4.27 and the Natural Science t-test was 3.60 with a t-table at a significant level of 5% of 1.67. The dimensions of t-count are greater than t-table. From these data it appears tahat there are differences in learning outcomes achieved by students in the experimental and control classes.
