Abstract

The low level of self-directed learning among students is a problem in this study and the limited research on Science, Technology, Engineering, and Mathematics-based Self-Regulated Learning in physical education is a gap in this research. Science, Technology, Engineering, and Mathematics (STEM) based on Self-Regulated Learning (SRL) is an alternative learning model in Physical Education. The purpose of this study was to determine the effect of application Science, Technology, Engineering, and Mathematics based Self-Regulated Learning to develop self-directed learning. This study used quasi-experimental method with a nonequivalent control group design and sampling used purposive sampling technique. The participants in this study were students VIII grade. Research was conducted in SMP Laboratorium School UPI with online learning and Limited Face-to-Face Meeting. The instruments of this study used the Self-Rating Scale of Self Directed Learning (SRSSDL). After the sample had completed the treatment, the results of data analysis showed that directed learning aspect was 0.027 with the criterion value (Sig.) = 0.05. Regardless of the results, this is supported by empirical evidence from student behavior, learning, and task making. They showed the development of students' abilities in the learning process did not depend on teachers, friends, class conditions and others. It can be concluded that implementation of Science, Technology, Engineering, and Mathematics (STEM) based on Self-Regulated Learning (SRL) has an effect on develop self-directed learning. This research contributes to learning innovation in physical education, so that teachers can apply this model on an ongoing basis to develop self-directed students. Future research needs to be done, for example trying to apply this model to develop other potentials in students such as motivation, cooperation, or responsibility.

Abstract

AbstractA common side effect of radiotherapy used in the treatment of head and neck cancers is the occurrence of structural and physiological alteration of the salivary gland due to exposure to ionizing irradiation, as demonstrated by conditions such as decreased salivary flow. Ionizing irradiation cause burst of reactive oxygen species (ROS) such as superoxide, hydroxil and hidrogen peroxide which induce activation of self-defense system such as superoxide dismutase and catalase. If this defense system could not diminish the excessive amount of ROS it would lead to oxidative stress which can be determined by rise of malondialdehide (MDA) levels. The aim of this research is to find out the influence of single and fractionated dose of gamma ray irradiation on superoxide dismutase and catalase activities and malondialdehide levels in rat submandibular glands at 24 hours, 3 weeks and 6 weeks after exposure of gamma ray irradiation. For this research, experimental laboratory was done. Sixty male Wistar rats aged 3-4 months (250-300 g) grouped into three. Group A (20 rats) as control group were not irradiated. Group B (20 rats) were irradiated with single dose (10 Gy) and group C were irradiated with fractionated dose (10 Gy in 5 fraction of 2 Gy/day) of Co60 Gamma ray, with their neck ventral surface exposed to the source. The rat submandibular glands were extirpated at 24 hours, 3 weeks and 6 weeks after irradiation and then analysed for superoxide dismutase and catalase activities using microreader and malondialdehide levels using spectrophotometer. There were significant differences (p:0,000) of superoxide dismutase and catalase activities and malondialdehide levels after gamma ray irradiation at evaluation time 24 hours, 3 weeks and 6 weeks. Superoxide dismutase activity in group B (10 Gy single dose irradiation) and group C (10 Gy fractionated dose irradiation) decreased in compare to group A (control). Catalase activity in group B decreased in compare to group A at 24 hours, in group C catalase activity increased in compare to group A. Malondialdehide levels increased in group B and C compare to group A at 24 hours, 3 weeks and 6 weeks after irradiation.

Abstract

The purpose of this study was to determine the correlation between the awarding of academic achievement awards to student athletes and their academic performance. The researcher used a quantitative approach with a questionnaire survey that was correlated with the student athletes’ report card grades. The sample in this study consisted of 146 student athletes at Junior High School 1 Baleendah. The results of the study indicate that there is a positive and significant correlation between the awarding of scholarships and academic performance. Scholarships, pocket money, and medals awarded by the organizers of competitions can improve the quality of student athletes’ learning at school, enabling their academic performance to compete with that of regular students, even though competitions do not hinder their learning. This study indicates that being both a student and an athlete does not hinder students from achieving academic success but rather serves as motivation for student athletes to strive harder for academic achievements. The implications of this study are that the athlete class program should be implemented more widely, especially in Bandung Regency, to encourage student athletes to be more active in academic pursuits so they can achieve both academic and sports achievements, and for schools to provide adequate facilities for student athletes.
