Effectiveness of Geogebra Learning With Scientific Approach To Vocational School of Technical Engineering 2 Binjai

Abstract

21st Century is known as the era of the information society, this can be seen from the emergence of the phenomenon of digital society. So we know the term industrial revolution 4.0. The industrial revolution 4.0 has an impact in the world of education in Indonesia, known as 21st-century learning, which is technology-based learning and requires students to be the center of learning. This is in line with the 2013 curriculum which applies a scientific approach. One of the software that can be used in mathematics education is Geogebra. Learning media as an alternative creates effective learning. The objectives of this study are: (1) to find out 80% completeness of student learning outcomes classically with KKM 75; (2) to find out the improvement of student learning outcomes; (3) to determine the timeliness in learning. This research is quasi-experimental. The study population numbered 60 people from class XI-1 and X-2, while the sample class X-1 numbered 30 people. Testing the research hypothesis using a one-party test and the cumulative frequency, paired t-test. The results showed (1) completeness of student learning outcomes in a classical manner that is 83.33%, indicating completion of completeness; (2) the value of sig <α, then the student’s posttest learning outcomes are better than the pretest; (3) appropriate use of time according to the teaching plan.
