Pengaruh Model Pembelajaran Jurisprudential Inquiry Terhadap Kemampuan Menulis Teks Editorial Siswa Kelas XII SMA Negeri 2 Tanjung Morawa

Abstract

This research was carried out with the aim of finding out the effect of the jurisprudential inquiry learning model on the ability to write editorial texts. The population of this study was all class XII of SMA Negeri 2 Tanjung Morawa, totaling 7 classes. The sample was taken with no more than 40 students per class, so class XII Science 2 had 35 students as the experimental class and class XII Science had 34 students as the control class. The instrument used is a test of the ability to write editorial texts. Data measurements were carried out twice, namely measurements in the experimental class and the control class. From the data processing, it shows that the ability to write editorial texts in class .05, standard deviation 13.15. This can be seen in the normality test, the jurisprudential inquiry learning model is L_count < L_table namely 0.205 < 0.337. Then in the conventional learning model L_count < L_table, namely 0.192 < 0.319. Because L_count is smaller than L_table, the two data above are said to be normally distributed. Likewise, the results of the data homogeneity test are F_count < F_table , namely 0.54 < 0.56, so the data comes from a homogeneous population. After testing normality and homogeneity, hypothesis testing was carried out, obtained t_count > t_table  with hypothesis test results of 6.35 and significance a = 0.05 and df = 35+34-2 = 67, so at the 5% level we obtained ttable = 1.99601. Thus it can be concluded that t_count > t_table , namely 6.35 > 1.99601, so the null hypothesis (H₀) is rejected and the alternative hypothesis (H_a) is accepted. This proves that the jurisprudential inquiry learning model is more influential in improving the editorial text writing skills of class XII students at SMA Negeri 2 Tanjung Morawa.
