The Influence of Card Sort Learning Media on Stuidents’ Learning Outcomes in Subtheme 1 How Clean Air Processes by Body in Grade V UPTD SDN 122337 Pematang Siantar

ABSTRACT


INTRODUCTION
Education is one of the bases for efforts to develop and increase student potential by encouraging and providing various facilities for the teaching and learning process .Education is also an area that is of great concern to every direction, especially Indonesia which has the potential to greatly increase education.Based on Law number 20 of 2003 article 1 (1), it explains that education is a place or forum that develops all human potential in order to create and have religious spiritual strength, intelligence, personal personality and the skills needed in himself, his family and society.as well as the nation.
Learning activities must be carried out in order to create a good learning process too.To achieve success, one way is to look at student learning outcomes.Which is an aspect that will be considered in planning a lesson from learning activities.In Boom's taxonomy concept , aspects of learning outcomes are divided into 3 domains, namely: 1) cognitive domain 2) affective domain 3) psychomotor domain (Magdalena, et al: 2020).4) Thus, the learning outcomes are in the form of students' abilities that they receive after receiving the subjects.From there the teacher can find out to what extent the students have understood the learning.
Based on observations made at UPTD SD Negeri 122337 Pematang Siantar in class V in May.The observation results obtained still show low learning outcomes with data on daily test scores for Indonesian language subjects, 41% of students have completed and 59% of students have not completed science subjects, 45% of students have completed and 55% of students have not completed them.Where there are still many students who have no interest in learning and students who are inactive, indifferent, and even like to chat with their classmates.They think that Indonesian and science lessons are boring, which results in many students feeling sleepy and bored during the lesson.In fact, there are no students who want to answer the questions given by the teacher after the learning process is complete.So this kind of implementation results in students having difficulty understanding the content of the material being presented as well as low student learning outcomes, where if the learning outcomes are low it will result in the learning process carried out at school not being carried out well .
As well as the solutions used to deal with these problems, as teachers must create a good and effective learning atmosphere, teachers must also be able to create a conducive learning environment or a classroom atmosphere that is pleasant, comfortable and clean.So that students are interested and can follow the learning well.By using Card Sort learning media.
The learning media that researchers apply is Card Sort learning media, where this learning media can help students to increase students' understanding of learning material and the learning material is more easily conveyed to students.Card Sort learning media is a learning media in the form of pieces of paper containing paper about the material that will be taught to students.The advantages of this Card Sort media are: Vol.1, No.5, 2023: 633-644 635 1) make it easier for students to receive lesson material 2) students are more enthusiastic and enthusiastic in learning 3) implementation is easy and simple 4) increase students' interest in learning The weaknesses in this Card Sort learning media are : a. Students are less active in speaking and giving opinions b.Students who don't understand will have difficulty adjusting to their groups c.If the teacher is not careful, it can take up time in providing learning material.
Especially in learning to maintain human respiratory organs so that it can teach students to know about maintaining human respiratory organs, and students create ideas or questions that can make them active in the learning process.That is why teachers must be wise in providing learning media that attracts students' attention so that the teacher's hopes and aspirations can be realized.
Based on the background above, the researcher is very interested in conducting research with the title "The Influence of Card Sort Learning Media on Student Learning Outcomes in Theme 2 Sub-theme 1 How the Body Processes Clean Air in Class V UPTD SD Negeri 122337 Pematang Siantar".

THEORETICAL FRAMEWORK
Conceptual framework can be prepared influence Card Sort Learning Media on Student Learning Outcomes in Class V in Theme 2 Subtheme 1 How the Body Processes Clean Air at UPTD SD Negeri 122337 Pematang Sianta r .
In observations made by researchers at UPTD SD Negeri 122337 Pematang Siantar, the resulting learning process tends to be teacher-centered, students are less active in the learning process and students tend to be passive due to being sleepy and daydreaming and learning seems boring and does not attract students' attention during the process.learning.
So teachers need media that can improve the learning outcomes of class V students at UPTD SD Negeri 122337 Pematang Siantar.Learning Media n Card Sort is a learning media that can be used to attract students' attention in understanding the lesson that will be delivered.The aim of creating Card Sort learning media is to change student learning outcomes that were previously low or high to become optimal and higher in the learning process.

METHOD
The research used in this research uses a quantitative approach.According to Sugilyono (2021), quantitative research methods are research methods that are based on the philosophy of positivism, used to research certain populations or samples, collecting data using research instruments, quantitative/statistical data analysis, with the aim of examining predetermined hypotheses.This research uses a Pre-Experimental Design type of research using The One Group Pretest-Posttest Design.
According to Sugiyono (2021) an experiment is a research method carried out by experiment, which is a quantitative method, used to determine the independent variable (treatment) against the dependent variable ( outcome) under controlled conditions.
In research, the results of the treatment will be known more accurately because the situation can be compared before the treatment was given.The following is a picture of One-Group Pretest-Posttest Design, Sugiyono (2021) O1 X O2 The population in this study were all students at UPTD SD Negeri 122337 Pematang Siantar with a total of 30 students.

1.Test validity
Of the 30 questions after the instrument test at school, there were 20 valid questions and 10 invalid questions.So what is distributed are questions with a total of 20 valid statements.Because the questions distributed are questions that meet several criteria which are assisted by the use of the Microsoft Excel 2010 application.

Reliability Test
The rehabilitation test aims to see the accuracy of the tool in assessing what it assesses.In this case, observe how each question item is determined in assessing or testing students' abilities and knowledge.Based on the results of the reliability test with the Kr20 model above, we can see that the value is high.Then it can be concluded that the data is declared reliable.

Data analysis
This research was carried out at UPTD SD Negeri 122337 Pematang Siantar in class V with 30 students as research samples.In this research, the scores from two variables consist of 20 questions in the form of multiple choices which were given to 30 students as research samples.These two variables are student learning outcomes before treatment (Pre-Test) and learning outcomes after treatment using Card Sort media learning (Post-Test).

Normality Test
The Normality Test is used to see whether the data obtained comes from a population with a normal or abnormal distribution.This normality test uses the SPSS program with the Komogorov-Smirnov program with Lilielfors correction criteria.The basis for decision making in this test is: The table above shows that the Melan N-Gain score and N-Gain percent are 0.76, which is included in the high category.

Discussion
Of Card Sort Teaching Media on Student Learning Outcomes in Theme 2 Subtheme 1 How the Body Processes Clean Air in Class V UPTD SDN 122337 Pematang Siantar .In this research, researchers used an experimental type of research using a One Group Pretest-Posttest Design research design.Before using Learning Media in the teaching and learning process, it is an effort to increase the effectiveness and quality of the learning process which can ultimately improve student learning outcomes.In this study, researchers used Card Sort Learning Media as learning media.However There are still difficulties in using this media, namely the ability required in the manufacturing process to make it more interesting, creative and innovative, so teachers must be able to apply Card Sort Learning Media.The ease of using this media is that the material is presented with certain points, making it easier for teachers to convey and explain the material to students.Based on existing theory, it is suspected that the learning outcomes of students who are taught using Card Sort Learning Media are better than students who are taught without using it.Card Sort Learning Media.Judging from the hypothesis testing data, it turns out that the assumption is correct.With the rejection of HO and supported by data obtained during the research, namely a comparison of study statistical scores showing that there were 30 people in the sample, with the lowest pretest score being 20 and the highest being 100.The lowest posttest score was 75, while the highest posttest score was 100, with an average The pretest score is 46 and the average is 82.In other words, learning using Card Sort Learning Media is better than learning without using Card Sort Learning Media.This is possible because of the different approaches when using media and when not using media.Using media can motivate students to be active, make the teaching and learning process more enjoyable and increase student motivation to seek information about subjects which can improve student learning outcomes in learning.Meanwhile, without using media, more students listen to the teacher's lecture so they are less effective in learning.The influence of Card Sort learning media on student learning outcomes, namely student learning outcomes where student learning outcomes have increased.
This researcher means that the hypothesis in this research is accepted, namely that there is an influence of Card Sort Learning Media on Student Learning Outcomes in Theme 2 Sub-theme 1 How the Body Processes Clean Air in Class V UPTD SDN 122337 Pematang Siantar.The results of this research are in accordance with previous research conducted by Yenti Juniarti et al (2022) which shows that there is an influence of Card Sort Learning Media on learning outcomes.So it can be stated that there is an influence of Card Sort Learning Media on student learning outcomes.
