The purpose of this study is to know determine whether diorama media with a scientific approachcan improve science learning outcomes for fifth grade elementary school students. This research is a type of quantitative research using the experimental method of True-Experimental Design research in the form of Posttest-Only Design. The variables of this study consisted of the independent variable (X) namely the diorama media and the dependent variable (Y) namely thelearning outcomes. The population in the study amounted to 75 students with 20 students asresearch subjects. Data collection techniques using tests and observations. Validation of the testinstrument was tested using the product moment correlation formula and the reliability test usingsplit-half. The data analysis technique used the T test, which was carried out after the normality andhomogeneity tests were known. The experimental class that was given treatment with diorama media obtained a posttest average of 79.50 and the control class obtained a posttest average of 61.00. The results of the t test with t table 2.024 obtained t count 4.349, it can be concluded that there is a significant influence on the use of scientific approach diorama media on science learning outcomes for fifth grade elementary school students.

This study aims to determine science learning by using experimental methods on cognitive learningoutcomes of fifth grade students of SD Negeri 195 Palembang. This research is a quantitativeresearch using the experimental method of True-Experimental Design research in the form ofPosttest-Only Control Design. The research population was all fifth grade students of SD Negeri 195 Palembang, totaling 131 students. The sampling technique used is Probability Sampling type Simple Random Sampling. The sample in this study was taken from class VA which amounted to 38 students and class VB which amounted to 32 students. Data collection techniques using tests ofstudent cognitive learning outcomes and observation. The instrument for measuring cognitive learning outcomes uses a posttest in the form of an objective test description. The validity of the test instrument was tested using the Product Moment correlation formula and to determine the reliability, it was tested using the Cronbach Alpha formula. Data analysis technique using t test. The results showed that the experimental class group obtained an average posttest value of 83.16 and the control class obtained an average posttest score of 57.97. The results of the t-test are 6.432 with a t-table of 1.996, meaning that it can be concluded that there is a significant effect between learning science using experimental methods on cognitive learning outcomes of elementary school students.

This study aims to determine the effect of the part and whole method on the long jump learning This study aims to determine whether the Non-Example Example Learning Model can improve Science Learning Outcomes of Class V Students at State Elementary School 195 Palembang. This research is a type of quantitative research using experimental methods, the type of research is True Experimental, PosttestOnly Design. The variables of this study consisted of the independent variable (X), namely the ExampleNon Example Learning Model and the dependent variable (Y) Learning Outcomes. The population in this study were all fifth grade students of SD Negeri 195 Palembang, totaling 131 people. The sampling technique used is the Simple Random Sampling technique. Data collection techniques in this study were tests and observations. The data obtained were then calculated using the SPSS.22 application. Validation of the test instrument was tested using the Product Moment correlation formula and the Reliability Test using Split-Half. The data analysis technique used the t test, which was carried out after knowing the normality and homogeneity tests. The experimental class that was given treatment with the example non example learning model obtained a posttest average of 84,688 and the control class obtained an average posttest of 60.36. With the hypothesis testing criteria, Ha is accepted if tcount > ttable with the acquisition of tcount 7,199 and ttable 2,002 then Ha received. The results of this study indicate that there is a significant effect between the non-example exampel learning model on the science learning outcomes of fifth graders at State 195 Palembang.

Pembelajaran IPA Berpendekatan Jelajah Alam Sekitar (JAS) Terhadap Hasil Belajar pada Kelas V SD Putri, Dinda Anisyah; Hetilaniar, Hetilaniar; Dirgantara, Marvinda Rizki Dita

The purposeof this study was to determine whether the approach to exploring the surrounding nature could improve science learning outcomes for fifth grade students at SD Negeri 32 Palembang. This research is a type of quantitative research using the experimental method of True-Experimental Design research in the form of Posttest-Only Design. The variables of this study consisted of the independent variable (X) namely the Surrounding Nature Exploration Approach (JAS) and the dependent variable (Y) namely learning outcomes. The population of this study were all fifth grade students of SD Negeri 32 Palembang, totaling 42 students who were selected using the Non-Probability Sampling technique with the Purposive Sampling method. Data collection techniques using tests and observations. The validity of the test instrument was tested using the product moment correlation formula and the reliability test using the split-half. The data analysis technique used the T test, which was carried out after the normality and homogeneity tests were known. The experimental class that was given treatment with the surrounding nature cruising approach (JAS) obtained an average posttest of 79,524 and the control class obtained an average posttest of 68,947. The results of the T-test with ttable 2.021 obtained tcount 2.521 it can be concluded that science learning approaches the Natural Exploration (JAS) approach to learning outcomes in class V SD.

This study aims to see and determine the effect of the SQ3R method on the reading ability of classstudents. The experimental method of this type of research is True-Experimental Design in theform of Posttest-Only Control Design. The research variable is the independent variable using the SQ3R method (X) and the dependent variable is reading ability (Y). The population of this study were all fourth grade students of SD Negeri 233 Palembang, totaling 49 students. Data collection techniques using tests and interviews. The instrument for measuring reading ability uses a posttest in the form of a multiple choice objective test. The validity of the test instrument was tested using the product moment correlation formula and to determine its reliability it was tested using the Kuder Richardson (KR) 21 formula. The data analysis technique used the t test, which previously had known normality and homogeneity. The posttest value of the experimental class was 81.43, the control class used the method of reading the posttest value of 73.33. The results of the t-test t-table 2.012 obtained tcount 2.296, there is a significant effect on the use of the SQ3R method on students' reading ability in determining the main idea of a paragraph.
