Abstract

The results study indicate that the learning process in class VII-A semester 2 of SMP Negeri 2 Fanayama is increasing. This increase was seen in the processing observation sheets student the activities through the process of cycle I, namely the average percentage of observations student the activity 71,39% and the percentage experiencing an increase in cycle II, which was 76,6%. 77,43% experienced an increase in the process through the second cycle obtained by an average of 82,82% which explained that learning outcomes students class VII-A semester II of SMP Negeri 2 Fanayama 2018/2019 Academic Year the discussion lines and angles there was an increase. This increase is seen the processing the results of learning test process through the first cycle obtained an average percentage success 73,82% and the percentage of incompleteness of 26,18%; processing results the second cycle learning process test obtained average with success percentage of 75,87% and with percentage of incompleteness of 24,13% thus results learning process of have reached the graduation target.

Abstract

The purpose of the implementation of this study was to determine the effect of the index card match learning model on student cognitive learning outcomes in Integrated Science subjects class VIII SMP Negeri 3 Maniamolo in the 2020/2021 Learning Year. This study uses a quantitative approach with a quasi-experimental method. The sample of this research is class VIII-A with 30 students and class VIII-B with 31 students. The instrument used is a learning outcome test which is divided into two, namely the initial test and the final test and documentation. Based on the results of data processing that has been carried out by researchers, the following results are obtained: "Based on the results of data processing that has been carried out and the calculation of hypothesis testing, it is obtained tcount = 3.62 and ttable = 1.67. This shows the value of tcount> ttable, then Ho rejects and accepts Ha, it can be concluded that there is an influence of the Index Card Match Learning Model on Student Learning Outcomes in Integrated Science Subjects for Class VIII SMP Negeri 3 Maniamolo 2020/2021

Abstract

This study aims to determine the effect of the Bamboo Dancing learning model on students' creativity in Biology subjects. The research method used was a quasi-experimental research design with a pretest and posttest group design. The study population was all students of class X-MIA, while the research sample was students of class X-MIA-a as the experimental class and class X-MIA-b as the control class. The results showed that the average percentage the initial creativity the experimental class students was 59.7% and the control class students 56.4%. Through the Bamboo Dancing learning model, the average percentage the final creativity the experimental class students was 83.8%, while through the conventional learning model the average percentage the final creativity control class students was 68.9%. Hypothesis testing obtained tcount = 10.292 while ttable at a significant level of 5% and dk = 17-2 = 15 with ttable = 2.132, it turns out that tcount> ttable or 10.292> 2.132 so that Ha is accepted. Experimental class students are able express ideas and be able to think creatively to solve problems. So it can be concluded that there is an effect of the Bamboo Dancing learning model on students' creativity where students able to think creatively to solve problems.

Abstract

This research motivated by the problem academic talent, especially in science-physics subjects, because many students do not achieve minimum mastery in science-physics subjects. Research sub-focus 1) The performance of science-physics teachers at the BNKP Telukdalam Christian Private Junior High School. 2) The academic talent of the seventh grade physics subject. The type of research used is qualitative research with a phenomenological approach. The results showed that 1) The performance of the science-physics teachers was good, where the Guidance and Counseling teachers carried out their duties well according to the function of Guidance and Counseling services. 2) Grade VII students have IPA-Physics academic talent, where students try to solve difficult problems by asking the IPA-Physics subject teacher, and looking for reference sources on the internet that have the same IPA-physics questions. The conclusion of the research on the role of science-physics teachers in developing students' science academic talent by providing knowledge about talent, teachers providing insight into knowledge about their talents, it can open up students' views about their talents more broadly.

Abstract

The laboratory is very closely related to practicum activities in learning science. The aim of this service to find out whether the science laboratory i utilized properly by teachers and students in learning science (physics, biology and chemistry) related to the laboratory. This type of research is quantitative descriptive research. Research results (1) The state of the Natural Sciences laboratory is in good category with a percentage value of 63.45%, (2) The Natural Sciences laboratory equipment has not met the standards set forth in Permediknas of the Republic of Indonesia number 14 of 2007 with a percentage value of 54.87%, (3) Frequency and the utilization of laboratory science not good enough with percentage value of 58.42%. It can be concluded that science laboratories are not utilized well by teachers and students due to inadequate equipment and materials.
