The CORE Model for Improving students behavior and learning outcomes the production technology development of Social Sciences Learning

Social studies subjects are one of the subjects that are not liked because the learning context is too monotonous containing memorization and readings that make the learning process saturated.  This study aims to determine the increase in social studies activities and learning outcomes in the development of production technology by applying the Connecting Organizing Reflecting Extending (CORE) learning model.  This study used the Classroom Action Research (CAR) or Penelitian Tindakan Kelas (PTK) method by Kemmis and Mc.Taggart models.  The results of this study were in the first cycle of student activity aspects of visual activities 71.8% (good), aspects of oral activities 69.2% (good criteria), and aspects of listening activities 77% (good).  In the second cycle, there was an increase namely the students' activities visual aspects to 83.3% (very good), aspects of oral activities 81.4% (very good), and aspects of listening activities 83.3% (very good).  For the final test results, students also experienced an increase.  The magnitude of the increase in the percentage of mastery learning from the initial data to the first cycle increased from 46.1% to 69.2%, while from the first cycle to the second cycle an increase from 69.2% to 92.3% of students who completed.  Thus, it can be stated that the CORE model can improve student learning outcomes towards social studies learning on the material development of production technology in fourth-grade students at SDN Salamjajar, Cisitu District, Sumedang region.


INTRODUCTION
In the implementation of education in schools there are three interrelated variables. The three variables are curriculum, teacher, and teaching and learning process. Curriculum development in Indonesia has been amended several times. Starting from the 1975 curriculum to the 2013 curriculum which has begun to be implemented in schools. The curriculum is a rule that is used in learning activities to achieve educational goals. The curriculum is a plan and arrangements that can use to manage learning activities and educational goals (Maulana: 2011).
Besides, teachers have an important position in the implementation of education. Under what was stated to  that the component that is considered the most important in learning activities is the role of a teacher. A teacher must lead the curriculum and transform it to students through teaching and learning.
Learning as a process of giving knowledge from the teacher to students to create the formation of attitudes and behavior in a better direction.
Following what was stated by that learning is the assistance provided by educators so that the process of acquisition of knowledge and knowledge, mastery of skills and behavior, and the formation of attitudes and beliefs in students (Sujana: 2012). Through the learning process, students' abilities can be developed if the learning activities are carried out by directing students to find concepts, not through acceptance of formation from the teacher. Social Sciences (IPS) learning is a science that studies events related to social sciences. In line with Nurkholiq suggested that IPS is an incarnation of an interdisciplinary approach from social science . IPS was different from other subjects. A teacher who teaches social studies subjects must be able to design learning activities by learning models and students' initial knowledge with research activities that can clarify the concepts to be learned.
Social studies is a vital subject and have a great influence. Leaving aside social studies subjects is the same as setting aside students' social life.
The impact is like juvenile delinquency that is leading to criminal acts in school-age often occur, fights between students, and even among students. This condition is a challenge for the world of education and needs to be used as a rationale for the need for innovation in social studies learning (Puspitasari, 2016). The innovation made more precisely is on how to make these social studies subjects liked by students. Alan J. Singer (2003) reports that feelings of inferiority and frustration often descend on social studies teachers in the United States where the country is the originator of the emergence of social studies or social sciences curriculum (Birsyada, 2014).
The saturation of social studies learning is also felt by students and teachers in Indonesia, the view of the construction of society in Indonesia to date still many assume that social studies are only rote, and there is almost no allure for learning (Birsyada, 2014). In social studies learning students are forced to remember various information without being required to understand and find that information based on their potential. This will have an impact on students who will have difficulty in understanding and memorizing subject matter and feeling easily bored (Al Ghazali et al., 2016). This anxiety was felt by Hariata et al (2017) that his research was motivated by observations that showed that one of the subjects that were monotonous and less attractive to students was IPS.
Thus, it was necessary to do innovations learning in social studies subjects that aim to make social studies learning attractive by students as learners or teachers as teachers.
The observations were done at SDN Salamjajar, Sumedang Region, in West Java, Indonesia. The learning process at the elementary school level is still teacher-centered. Especially, the concept was conveyed by the teacher and is considered too difficult for students to understand if the lecture method is still used. Especially if the lecture method is too dominant in the learning process. From the results of daily tests of students can also be seen that many student learning outcomes are less than the minimum completeness criteria or Kriteria Ketuntasan Minumum (KKM) that have been implemented in schools. Learning outcomes are the achievement of educational goals in students who follow the teaching and learning process. According to Purwanto (2008), learning outcomes are "change learning outcomes are "changes in behavior that occur after following the teaching and learning process under educational objectives". Besides, student activities tend to be less active.
It can be concluded, a teacher must be able to direct students to link the material delivered with daily life and use innovative learning models that can develop student creativity and improve student learning outcomes. One innovative learning model is the Connecting Organizing Reflecting Extending (CORE) learning model. The CORE learning model can be used to enable students to build their knowledge. This CORE model combines four important constructivist elements, namely connecting to student knowledge, organizing students' new content (knowledge), providing opportunities for students to reflect on them, and giving students opportunities to expand knowledge (Humaira et al., 2014).
With the implementation of the CORE model, it is expected that social studies learning outcomes can improve. For this reason, a teacher must be able to apply the model with the steps of the CORE model in teaching and learning activities on the material development of production technology. This study is supported by the results of Retnowati and Aqiilah's research (2017)

This research used in this study is Classroom Action Research (CAR).
The design used is Kemmis and Mc Taggart is known as the spiral model.
The research was located at SDN Salamjajar, Cisitu District, Sumedang region, West Java, Indonesia. The subjects in this study were the 4 th -grade students of SDN Salamjajar, totaling 23 students. Data collection techniques used in this study were the observation of student activities, observation of teacher performance, learning achievement tests, and documentation.

Results
The results of this study in the form of student activity data and student learning outcomes in the initial data stage, cycle I, and cycle II. To find out the comparison of the results of student activities from the initial data to the second cycle shown in the following Tabel 1. Based on Tabel 1, it can be seen that student activity has increased from the initial data to the second cycle. The aspects assessed in student activities are visual, verbal, and listening activities. In the second cycle, data on the results of student activities have reached the expected criteria with a limit on the achievement of the average student activity in one class that is 80.0% with the interpretation as good criteria.
The learning outcomes data was taken by using a written test instrument with KKM which is amount 70 exacta. The research will be said to be successful if students who score above KKM are more than 70 as seen in Table 2. Based on Table 2, it can be concluded that student learning outcomes have reached the expected target in the second cycle with the percentage of students who scored above the KKM of 92.3%. The presentation of the comparative data increased activity data and student learning outcomes in a graphical form that can be seen in Figure 4 and  The results of this study showed that student activities reached a percentage of 80.0% and 70.0% of learning outcomes. Thus, it could be stated that this study was terminated until the second cycle because it had reached the expected criteria. The development of the learning process occurred. Every process had some different criteria. The teacher must be able to teach students with various skills to get better grades than before.

The Process of Using the CORE Model
The

Results of Using the CORE Model
Student learning activities on aspects of visual activities, oral activities, and listening activities have increased. In the aspect of visual activities, from the initial data to the first cycle increased from 64.1% to 71.8%, while from the first cycle to the second cycle there was an increase from 71.8% to 83.3%. In the oral activity aspect, cycle I showed about increasing 56.4% to 69.2%, while from the first cycle to the second cycle there was an increase from 69.2% to 81.4%. The aspect of listening activities, from the initial data to the first cycle increased from 61.5% to 77.0%, while from the first cycle to the second cycle there was an increase from 71.8% to 83.3%.
The final exam increased, this is evident from the increasing number of students who completed, the percentage of completeness, and the average value. The magnitude of the increase in the percentage of mastery learning from the initial data to the first cycle increased from 46.1% to 69.2%, while from the first cycle to the second cycle an increase from 69.2% to 92.3% of students who completed. The CORE model has used widely in some research. They found a practical framework of the effect of the CORE model in the learning process. As a study conducted by Muizaddin and Santoso (2016), the CORE model gave improving learning outcomes in office administration subjects. In this research, it is proven that the application of the CORE model in improving student learning outcomes has increased. A similar opinion was expressed by Safitri et al (2014) that the application of the CORE model can increase the creativity and learning outcomes of History with the results in the first cycle of cognitive learning outcomes obtained a percentage of 70.96%, in cycle II it increased 9.09% to 77.41% in cycle 3 it increased 8.3483.87%. Beniasih et al (2015) suggested that the results of his research showed a comparison of average science learning outcomes of students who were taught with CORE models assisted by concrete media larger than students who were taught with conventional models (23.36 > 19.06). It could be concluded that student learning outcomes both from different subjects such as Natural Sciences and History in low classes, as well as subjects introductory to office administration in high class can be improved using the CORE models.
Besides improving learning outcomes, the CORE models can also improve understanding such as mathematical understanding and understanding of students' science concepts. Improved mathematical understanding is evidenced by research conducted by Deswita et al (2018) that based on data analysis, it was found that increased mathematical Then, the performance of teachers in the second cycle has reached 88.3% of all aspects assessed and included very good and optimal interpretation.
Thus, it can be stated that the performance of the teacher in the implementation of learning cycle II action has reached the specified target.
Student final test results have increased, this is evident from the increasing number of students who completed, the percentage of completeness, and the average value. The magnitude of the increase in the percentage of mastery learning from the initial data to the first cycle increased from 46.169.2%, while from the first cycle to the second cycle an increase from 69.292.3% of students who completed. Thus, it could be stated that the CORE models can improve student learning outcomes towards social studies learning on the material development of production technology in 4 th grade students at SDN Salamjajar, Cisitu District, Sumedang Region, West Java province, Indonesia.
