Abstract

This study aims to determine the effect of the application of cooperative learning model two stay-two stray towards learning outcomes and learning activities of students on the subject of colloids in the 2nd half of class XI SMAN 2 Sidikalang. This type of research is an experimental research. The study population was all students in grade XI natural sciences at SMAN 2 Sidikalang. Samples were taken at random as much as 2 classes and student samples randomly assigned 40 people per class. This study uses the initial and final test design randomized control group, where both classes were given a different treatment, a class using Learning Model Two Stay-Two Stray, and one other class using conventional learning model in the form of group discussions. Based on the results of data processing, obtained an average improvement of learning outcomes in the experimental class = 70.00%, while the control class = 46.32%. Testing the hypothesis on learning outcomes is done by using the t test (the test right) with α=0.05, db = 78 obtained t (3.98)> t table (1.68). This indicates that the t arithmetic is outside the reception Ho Ha accepted meaning. Likewise with the hypothesis of the learning activities of students, Ho was rejected because at α = 0.05, db = 78 obtained t (2.87)> t table (1.68)., It can be stated that there is the effect of the application of cooperative learning model two stay-two stray towards learning outcomes and learning activities of students on the subject of colloids in the 2nd half of class XI SMA N 2 Sidikalang. This type of research is an experimental research. The study population was all students in grade XI natural sciences at SMAN 2 Sidikalang. Results of processing data correlate with the learning outcomes of students learning activities obtained positive correlations were low and the experimental class is r = 0.44.

Abstract

This research is a quantitative research which aims to determine the effectiveness of the use of online crossword puzzle learning media in increasing student interest in learning. The population in this study were all students of SMA Widya Manggala. The sample in this study was selected using purposive sampling based on topic considerations. The research design was pre non test and post non test experimental control design. The learning interest questionnaire instrument used in this study was validated by expert validators. The results of the normality test for the Shapiro-Wilk approach show that the significance value (Sig.) Is 0.101. If associated with the normality criteria 0.101 is greater than 0.05 (0.101> 0.05). This means that the research data is normally distributed and can be analyzed using parametic statistics, in this case the one-sample t test. The normality test carried out in this study is a hypothesis test using SPSS 24, the significance value (Sig.) Of 0.000 is smaller than 0.05 (0.000 <0.05), so Ho is rejected and Ha is accepted. Hypothesis test results obtained that further gain test is carried out to determine how much increase in student learning outcomes. The result of the gain test is 0.336 with the medium category.
