Abstract

In distance learing or online, interesting learning innovations are needed to improve self-learning skills for students. The RQA (Reading, Questioning, And Answering) learning model is teaching oriented learning self-learning skills for students. This study aims to analyze the influence of learning models RQA on enhancement self regulated learning and learning result of student on the subject of  Matriks class XI SMA Negeri 1 Batang Angkola. The quasi experimenttal study used a design “nonquevalent control group design”. The sample of this research is student of class XI MIA 1 as experimental class with RQA model and XI MIA 4 as control class with conventional learning. In the research, technique of collecting data using test and questionnaire. Data analysis with Manova, using the app SPSS 21 for Windows. The result of the research analysis of the questionnaire indicated that the significance value of 0,000 < 0,05 which means that there is an influence of  RQA model on enhancement self regulated learning of student class XI SMA Negeri 1 Batang Angkola. Than, the result of the research analysis of test score indicated that the significance value of 0,000 < 0,05 which means that there is an influence of  RQA model on enhancement learning result of  student class XI SMA Negeri 1 Batang Angkola.

Abstract

Penelitian ini bertujuan antara lain : untuk mengetahui pengaruh penerapan model PACE terhadap kemamapuan pemecahan masalah matematika siswa pada materi theorema pythagoras di MTs YPKS Padangsidimpuan. Jenis penelitian ini adalah Quasi Eksperimen. Subjek penelitian ini adalah kelas VIII-1 dan VIII-2 yang berjumlah sebanyak 52 orang. Untuk mengukur kemampuan pemecahan masalah matematika siswa. Hasil penelitian menunjukkan terdapat perbedaan yang signifikan antara lain nilai rata-rata kelas eksperimen dan kelas kontrol. Hasil analisis data diketahui bahwa terdapat pengaruh penerapan pembelajaran PACE lebih baik dibandingkan dengan metode konensional. Rata-rata hasil belajar siswa pada kelas Eksperimen sebesar 84,03 dan untuk kelas Kontol rata-rata sebesar 76,34. Hasil uji statistik diterapkan dalam penelitian ini diperoleh rhitung sebesar 0,689, sementara rtabel nya 0,388. Dan nilai rxy nya sebesar 0,747, termasuk dalam kategori kuat. Berdasarkan dari rumus N-Gain kita dapat melihat bahwa siswa yang ditelitih termasuk dalam kategori tinggi dengan nilai sebesar 5,378, dan dapat disimpulkan dalam temuan penelitian bahwa hasil belajar menggunakan model PACE lebih baik dari pada menggunakan metode konvensional dengan presentase peningkatan sebesar 10,07 % berpengaruh tehadap kemampuan pemecahan masalah matematika siswa pada materi theoema pythagoras. Bertolak dari hasil penelitian dan kesimpulan tersebut, maka dikemukakan saran untuk meningkatkan kemampuan pemecahan masalah matematika siswa dengan model PACE, sehingga tampak pengaruh yang besar terhadap kemampuan pemecahan masalah matematika siswa dan memperoleh mamfaatnya.

Abstract

This research aims to determine the influence of learning in understanding associations through the Blended Learning learning model in class VII of SMP N 5 East Angkola for the 2023/2024 academic year. In this study, the sample was taken from the population using simple random sampling, namely the researcher took the sample randomly without paying attention to the strata in the population. This type of research is Quasi Experimental Research. The research subjects were class VII-2, totaling 20 people. There were 13 women and 6 men. The instrument used is a test. The test used is an essay form test with 5 questions. For final data analysis using Simple Linear Regression. The constant (a) is 12.694, meaning that if the Blended Learning influence level variable is 0, then the learning outcome volume variable has a value of 12.694. The regression coefficient for the Blended Learning variable has a positive value of 36.863, indicating that if it increases, there will be an increase of 36.863. The coefficient has a positive value, meaning that there is a positive relationship between Blended Learning and Microsoft Power Point.

Abstract

This study sought to examine the impact of ice breaking techniques on the ability of students at SMP Negeri 5 Angkola Timur to comprehend physical science information. The participants involved in this study were exclusively students from SMP Negeri 5 Angkola Timur. The research utilized cluster sampling, selecting two classes (VII1 and VII2), each comprising thirty students. A quasi-experimental design was employed, distinguishing between an experimental class and a control class. A multiple-choice test comprising Twenty questions on science process skills served as the research instrument. Prior to the study, The exam questions' reliability and validity were evaluated. Validity scores were obtained from students before subjecting the data to analysis through homogeneity tests, normality tests, and t-tests in both the pretest (prior to treatment) and posttest (following treatment) classes. The results indicated that the utilization of ice breaking significantly influenced the physical science process skills of students in the posttest class at SMP Negeri 5 Angkola Timur.
