Abstract

The purpose of this study was to determine the contribution of body mass index to the level of physical fitness of junior high school students in Medan City in 2023. This study used descriptive analytic method. The sample amounted to 23 people, obtained by purposive sample. To determine the correlation of body mass index to the level of physical fitness is sought using the product moment formula. This research uses body mass index test instruments and physical fitness tests carried out to find out data on research variables, namely body mass index data and student physical fitness tests. From the results of statistical analysis, the correlation coefficient between body mass index and physical fitness is rcount = 0.55. To find out how much the contribution of body mass index to the level of physical fitness is calculated with R = (0.55)2 x 100% = 30.25%. The contribution is 30.25%. Thus the hypothesis that states there is a contribution of body mass index to the level of physical fitness of junior high school students in Medan City in 2023 can be accepted in this study. This research opens insights into knowledge for teachers, especially physical education teachers so that this information can be applied in schools.

Abstract

The development of information and communication technology has had a significant impact on the world of education, including in the process of physical education learning. Learning, which was previously only done conventionally, has now shifted towards digitization and the use of application-based technology. This study aims to examine the effectiveness of mobile application-based blended learning in improving students' cognitive and affective competencies in physical education. The method used is a quasi-experiment with a pre-test and post-test control group design. The research subjects consisted of 60 high school students divided into two groups, namely the experimental group (n=30) who used mobile application-based blended learning and the control group (n=30) who used conventional learning. The results showed that the experimental group experienced an increase in cognitive scores from 56.4 to 82.7 and affective scores from 60.1 to 85.3. Meanwhile, the control group experienced an increase in cognitive scores from 55.8 to 69.4 and affective scores from 59.7 to 70.2. The t-test results showed a significant difference between the two groups (p < 0.05). This study concluded that mobile application-based blended learning is effective in improving students' cognitive and affective competencies.
