Abstract

This Research and Development (R & D) aims to produce more innovative statistics teaching materials by integrating them into guided, valid, practical and effective guided learning models in accordance with the National Standards of Higher Education. In addition to improving the quality of student learning outcomes in the course of statistics at the Universitas Quality. Furthermore, to know the effectiveness of teaching materials statistics development results that have been applied at the University of Quality. The study population is all students of PGSD Universitas Quality academic year 2017/2018. Sampling technique by using Purposive Sampling, which is student of semester V that take course of statistics. This research method uses Research and Development (R & D) method that adapted and modified by Borg & Gall. The work steps in the study include: (1) preliminary study, 2) development of teaching materials, 3) implementation of instructional use, 4) product effectiveness test. Instrument used in this research is achievement test of learning result. Furthermore, to test the hypothesis used t-test.

Abstract

This study aims to determine the differences in students' physics learning outcomes who were taught using the Contextual Teaching and Learning model with the conventional learning model for class XI of SMA Swasta Advent 1 Medan. This type of research is an experimental research with a pretest-posttest group design. The population in this study were all students of SMA Advent 1 Medan. The sampling technique was carried out randomly (Cluster random sampling), namely class XI-1 as an experimental class taught using the Contextual Teaching and Learning model and class XI-2 as a control class taught using a conventional learning model. Each class consists of 32 people. The instrument of this research is a multiple choice test of 20 items with 5 choices, the instrument is first tested on students outside the sample to determine the validity, reliability, distinguishing power and level of difficulty of the questions. From the data analysis, the average pretest value for the experimental class was 45.78 with a standard deviation of 6.67 and the posttest average value was 85.15 with a standard deviation of 5.63, while in the control class, the pretest average value was 52.26 with a standard deviation of 12.32 and the posttest average value. 68.21 with a standard deviation of 7.12. Before testing the hypothesis, the normality and homogeneity of the data were first tested. From the results of the preliminary test, it was found that the two data came from a population that was normally distributed and homogeneous. The results of hypothesis testing using the t-test obtained tcount = 4.36 > ttable = 2.002 so that it can be concluded that there is a significant difference in the use of Contextual Teaching and Learning models on student physics learning outcomes in class XI SMA Swasta Advent 1 Medan.

Abstract

Salah satu model pembelajaran yang dapat memfasilitasi siswa dalam mengembangkan kemampuan berfikir secara optimal, memperhatikan latar belakang kemampuan pemecahan masalah dengan strategi konflik kognitif dalam perubahan konseptual adalah model pembelajaran (Predict-Observe-Explain) POE. Penelitian ini bertujuan untuk mengetahui adanya perbedaan hasil belajar konsep dasar IPA mahasiswa yang diajar dengan menggunakan model pembelajaran POE dengan model pembelajaran konvensional. Penelitian ini adalah penelitian eksperimen semu dengan rancangan nonequivalen post-test only control group design. Berdasarkan hasil penelitian dan pembahasan diuraikan simpulan sebagai berikut. Terdapat perbedaan hasil belajar konsep dasar IPA antara kelompok siswa yang belajar dengan model POE dan model pembelajaran konvensional (F=28,177; p<0,05). Terdapat perbedaan hasil belajar konsep dasar IPA antara siswa yang memiliki gaya belajar visual, gaya belajar auditori dan gaya belajar kinestetika (F=11,573; p<0,05).
