This research aimed to calculate the increase of students’ mathematics critical thinking ability in Senior High School who taught with Flip-Problem Based Learning based on LMS-Google Classroom. This research is quasi-experiment research used pre-test post-test control group design research. Sample in this research is 60 students divided into two research groups, 30 students in the experiment group (taught with Flip-Problem Based Learning) and 30 students in the control group (taught with Problem-Based Learning). The homogeneity test and normality data test used Levenes’ test and Kolmogorov Smirnov test. The result of the homogeneity test and normality data test is homogenous and distributed normally. Based on the result of the homogeneity test and normality data test, hence the hypothesis research test used Independent Sample T-Test. The test result showed that mathematical critical thinking ability for students’ Senior High School who taught with Flip-Problem Based Learning based on LMS-Google Classroom. The result proved that the mathematics learning process of Flip-Problem Based Learning has a positive and significant effect on students’ mathematics critical thinking ability. Based on this research result, Flip-Problem Based Learning was recommended to be applied in mathematics learning. LMS-Google Classroom can also be one of the solutions in mathematics learning based on digital.
One of the supporting factors for success in the learning process is the use of learning media. One of the existing learning media but not yet fully used is smart circuit learning media. In this study used quantitative experimental methods, data analysis using statistical formula. The population in this study were all seventh grade students in the even semester of Islamic School of Bandar Lampung in the academic year 2018/2019. The population is spread in 7 classes. Two classes were sampled, namely class VII C as the experimental class and VII D as the control class. Sampling uses techniques cluster random sampling. Based on the results of research that the authors describe that results tcount=2,93from the distribution table at the level 5% known ttabl =1,99 and at the level 1% known ttable=2,65. Proven tcount>ttableso that it can be concluded that there is an influence of the application of smart circuit learning media to the mathematics learning outcomes and the average mathematics learning outcomes that apply smart circuit learning media are higher than the average results Mathematics learning students who apply conventional learning media to class VII students in the even semester at Islamic School of Bandar Lampung.
This research aimed to developed of student worksheet and statistical thinking ability test instrument for Senior High School's student based on local culture and accordance with the provisions of Curriculum 2013 in North Sumatera, Indonesia. The special purpose of this research was to analyze and to formula the purpose of mathematics lesson in statistical thinking ability and also to develop to try out the students worksheets based on local culture developed. Subjects in this study were eleventh grade students of Senior High School. This research was a development research using 4D type created by Thiagarajan, Semmel and Semmel. The development process of these research consists of four phases: define phase, design phase, development phase, and disseminate phase. From the preliminary reserach results, we obtain that student worksheet and test instruments of statistical thinking ability based on local culture and accordande with Curriculum 2013 were valid, practice and effective to be use in mathematics learning at Senior High School
Pembelajaran daring adalah salah satu kebijakan pemerintah untuk mengurangi jumlah penduduk yang terinfeksi virus corona di Indonesia. Sejak diberlakukan kebijakan tersebut, tenaga pendidik memanfaatkan media pembelajaran daring untuk membantu proses pembelajaran. Untuk mengetahui apakah terdapat pengaruh penggunaan platform Youtube sebagai media pembelajaran online terhadap kemampuan matematis merupakan tujuan dari penelitian ini. Metode penelitian ini adalah kuantitatif. Data yang diperoleh dianalisis menggunakan uji Wilcoxon dengan SPSS. Sebelum uji Wilcoxon, kenormalan dan kehomogenitasan datanya diuji terlebih dahulu. Hasil analisis data menunjukkan bahwa terdapat pengaruh yang positif penggunaan platform Youtube terhadap kemampuan matematis. Rata-rata kemampuan matematis setelah menggunakan media pembelajaran daring Youtube meningkat. Respon mahasiswa terhadap media pembelajaran daring Youtube sangat baik.
The use of learning media is one way to support the government in socializing the era of industrial technology 4.0. Learning media as a solution to students' low mathematical communication skills. One of the learning media that is proven to be able to improve students' mathematical communication skills is Autograph. This paper describes how much influence the use of Autograph learning media has on students' mathematical communication skills. The method used in this research is experimental. Before using the Autograph learning media, a pretest was carried out and after using the Autograph learning media, a post-test was carried out to determine the increase in students' mathematical communication skills. From the results of the pre-test and post-test data analysis, it was found that the Autograph learning media had a positive effect on mathematical communication skills. The average of students' mathematical communication skills taught with the help of Autograph media was higher. The use of Autograph learning media in learning makes students more active in discussions, dares to express opinions using mathematical language to express mathematical ideas correctly and can interpret mathematical data in the form of pictures or graphics.
