INFLUENCE OF THE USE OF TECHNOLOGY THROUGH PROBLEM BASED LEARNING AND INKUIRI MODELS ARE LEADING TO SCIENTIFIC COMMUNICATION STUDENTS CLASS VII

Problem Based Learning (PBL) and guided inquiry learning model develops intellectual ability as part of mental process. The purpose of this research is to know the difference of scientific communication ability between students who learn to use PBL model and guided inquiry, and to know whether there is influence the use of technology through PBL model and guided inquiry model to student scientific communication. The experimental research was conducted in 2 schools (Junior High School & Madrasah Tsanawiyah) in Grobogan District. Examples consisted of 10 classes with 6 PBL model learning models, 4 guided inquiry model and 1 control class. The sample size is 352 students. Instruments using student worksheets and student research reports. The analysis used a one way variance with a significance level of 5% supported by students’ skill and classical completeness. The results show the PBL model by giving the video at the beginning of learning gives the biggest influence with the average 83,6. The conclusion of this research is the better model of PBL in terms of individual capability, guided inquiry model better in terms of classical mastery. Improving scientific communication skills more effectively using PBL by providing video at the beginning of learning, followed by guided inquiry model with scientific reasoning. scientific communication skills more effectively using PBL with early video-giving activities and guided inquiry models with scientific reasoning.


Introduction
Learning is a process of interaction of learners with educators and learning resources that occur in the learning environment. The main purpose of the learning process is to achieve the learning objectives supported by various components of learning. Students and teachers are a major component of the learning process. The learning process requires a good reciprocal relationship between teachers and students, so the purpose of learning can be done well.
The learning process that emphasizes the skills of the science process will build students' self-understanding from the beginning to the end of learning. The learning process of natural Sciences emphasizes the provision of direct experience to develop the competence to understand the material appropriately. The learning model is applied with attention to student involvement in knowledge building when applying the lesson. The use of models in the application of learning also equips students with scientific literacy through experiments while in the learning process.
Initial studies in three junior high schools with the same school accreditation, in Grobogan district concluded that the application of science learning model in the teaching and learning process has not fully imparted the skills of the science process. Commonly applied learning patterns are lectures, discussions and group work. Students feel bored with the learning pattern. They want teaching and learning activities of science with observation and research activities that utilize the school environment. Students are not yet accustomed to communicating scientifically. When the learning process of natural Sciences is seen from the result of the assessment of group work report, the report made still does not meet the component of group work report. This is because students are not yet accustomed to scientifically communicating the work of groups of students.
The learning process is not only to learn from the guidebook given to the students, but the planting and application of the concept of natural Sciences emphasizes the application of everyday life in the environment around the students. The form of assignment (whether searching on the internet, clipping or other supporting literacy sources) is expected to make students motivated in learning. However, when given the assignment of both clipping and student papers are still experiencing difficulties in learning the concept of science.
Learning model is an important element to run student learning activity in school. Implementation of a good learning model on students will facilitate teachers in teaching, and make the learning process good and interesting for students. Through the learning model, teachers can assist students in finding information, skills, ways of thinking, expressing ideas, interacting, taking responsibility and training students' courage Chang, Wang, Ko, Yu, Lin, Tsai, (2017). The literature review used comes from pre-existing research and can be used as the theoretical basis for the research conducted. Here's the title and relevant research results.
Based on the guided inquiry research that has been done by Arslan (2014) that the implementation of the model and the approach that gives students feel comfortable and comfortable to the science learning so that the value obtained by the students beyond the minimum mastery criteria (KKM). Ruiz-Gallardo, Castaño, Gómez-Alday, Valdés (2011) shows that the guided inquiry learning model has an impact on improving conceptual understanding and developing students' creative thinking skills.
Based on preliminary data in the field, students are still unfamiliar in communicating scientifically. Researchers try to raise the problems experienced by students in the form of obstacles in scientific communication written secera in the form of results of observations and lab reports. In this study, the researcher chose the problem based learning model (PBL), and guided inquiry model. From the background of the above problems, further research is needed on the analysis of the difference of scientific communication skills of grade VII students on natural Sciences material based on PBL model and guided inquiry. The expected result of this research is to know the influence of PBL model and guided inquiry to the students' scientific communication ability on the science material of class VII.
The PBL model is a learning model with a learning approach to authentic problems so students can build their own knowledge, grow on higher skills. The PBL model includes asking questions or problems, focusing on interdisciplinary linkages, authentic inquiry, cooperation for critical thinking and problem solving. The inquiry model emphasizes maximum student activity to search and discover. It means that the inquiry model puts the students as subject of learning. In the learning process, students not only act as recipients of the lessons through verbal teacher explanations, but they play a role in finding the essence of the subject matter themselves. In addition, all activities undertaken by students are directed to find and find their own answers from something in question, so it is expected to foster self-confidence. Guided inquiry creates the effectiveness and efficiency of time in teaching because of student-centered learning and the role of the teacher as a facilitator and student guide / mentor. Both PBL and inquiry learning have direct implications such as the progress of learning attitudes, independence, scientific thinking ability, discussion ability, and student cooperation. In studying science the students are not only required to master the thinking skills but also the students are also expected to communicate the results of the product in the form of works / reports both written and oral. Due to the close connection between the ability to think by communicating scientifically. Agreeing with Santrock in Sarwi, Khanafiyah and Rusilowati, (2013) thinks reasoning and arguing can be reinforced in scientific communication skills.
The purpose of this research is to calculate the difference of scientific communication ability of students learning using PBL model and guided inquiry, to calculate the influence of PBL model on students' scientific communication, and to calculate the influence of guided inquiry model to students' scientific communication.

Methodology
This research is using experimental method. The population in this study are 16 classes in 2 Junior High Schools in Purwodadi and Madrasah Tsanawiyah in Grobogan District. Each class has 32 students. This population selection refers to the same school accreditation and is located in Grobogan District. The data collection technique is done by purposive sampling by looking at the characteristics of each class that have been consulted first with classroom teacher. In each school, five classes were selected to be used as experiments divided according to 3 classes using the PBL model (PBL with early discourse of activity, PBL model with early demonstration activity, PBL model with video giving at the beginning of activity) and 2 classes using Scientific reasoning and without Scientific reasoning. The researcher took 1 control class using the usual practicum model without PBL and Guided Inquiry (using only lectures and practices with the teacher).
The instruments of this study were in the form of student worksheets (LKS), the format of the student research assessment report format, the scientific communication assessment sheet, the student response questionnaire and the student's cognitive value. Data analysis techniques using elements of normality test, homogeneity, and hypothesis testing with ANOVA test. The use of worksheets to help maximize the learning model that is applied. Reports on research results are used to assess scientific communication skills based on prepared assessment sheets. There are nine criteria that researchers use in assessing students' scientific communication: 1) the ability to answer the need for observation. 2) Considerations in discussions raised by students who are submitted in scientific research.
3) Submission of observation variables. 4) Submission of data acquisition procedures. 5) delivery in processing and analyzing data. 6) Presentation of data. 7) Submission of appropriate media to prepare data processing results. 8) Submission of written data. 9) Use of appropriate language, symbols, and terminology for the field of Natural Sciences.

Result
Data includes anova test results and completeness test results as well as classical. For anova calculations, the researcher uses Microsoft's excel 2010 help shown in Table 1, Table 2 and Table 3. The results of classical exhaustiveness test of each model at Junior High School in Purwodadi and Madrasah Tsanawiyah with each class of 32 students showed that the percentage of scientific communication execution PBL model with the initial activity of discourse is 78.1% with z arithmetic -8.5 and 75% with z arithmetic -8.5, PBL with 84.4% initial demonstration activity with z count -8.5 and 81.3 % with z arithmetic -8.5, PBL with 87.5% initial video activity with z arithmetic -8.5 and 84.4% with z arithmetic -8.5, guided inquiry with scientific reasoning 93.8% with z count -8.5 and 87.5% with z count -8.5, inquiry guided without scientific reasoning 78.1% with z arithmetic -8.5 and 81.3% with t arithmetic -8.5. Completeness of the ability to apply PBL learning model shows the highest score especially on PBL learning with early video activity because PBL is a good technique to increase student activity, comprehend the content of the lesson and challenge student ability and give satisfaction to find new knowledge for student. In addition, the students' cognitive learning outcomes show the highest score among other model uses aimed at the student's daily repeat value after the application of the PBL model by giving the video at the beginning of the learning with an average student score of 8.63. In line with what Liu, Du, Zhang, Zhou, (2019) that PBL positively influence the significant implementation of problem based learning on the independence of science learning. By giving early activities of the video the students can be motivated and know what will be done later to solve the problems given by the teacher. From the results of data analysis in each class showed that learning using the PBL model gives influence to students' scientific communication both PBL model is given the early activities of discourse, demonstration and video. With the PBL learning model can achieve the learning objectives and the average student has exceeded the established KKM that is 75. Giving initial activity in the form of discourse is the lowest result in the analysis of researchers. It is possible students have not really know what the students will do later because the delivery is still an oral discourse and question and answer between teachers with students before doing observation activities. Agreeing with Benli and Sarikaya (2012) states that the essence of PBL presents a variety of authentic and meaningful problem situations to students, which can serve as a springboard for investigation and investigation. PBL is designed to help students develop thinking skills and problem-solving skills, learn the roles of adults and become independent learners. In line with Nicholls (2014), Morgado and Leite (2013) stated that the purpose of PBL is to help students develop thinking skills and problem-solving skills, learning the role of an authentic adult and becoming an independent learner.

Classic completeness at Junior High School in Purwodadi Grobogan
The result of the research shows that there is influence between guided inquiry model to students' scientific communication in terms of mastery of ability by comparing control class class and experiment. The inquiry model is guided by scientific reasoning which gives higher influence compared to guided inquiry model with scientific reasoning in terms of mastery of the ability and classical completeness. From the results of data analysis shows that the use of model inquiry model guided by scientific reasoning and guided inquiry model without scientific reasoning. Gives effect to the mastery of ability where the average student has exceeded the applied KKM that is 75. The use of guided inquiry model with scientific reasoning is considered more rather than the use of guided inquiry models with no scientific reasoning with higher completeness results in the two different sample schools. This also agrees with the research of Khanafiyah & Rusilowati (2010) that inquiry gives students the freedom to develop creativity, learners will be more creative in developing their experimental objectives, and improve the ability to understand the material. Agree with the research McNew-Birren and Kieboom (2017), Kant, Scheiter and Oschatz (2017) that the application of inquiry learning triggers the increase of the students' process skills in practicum. In line with Roller and Zori (2017), Howell and Saye (2018) the inquiry model involves a process of exploring nature that leads to the process of asking questions, making discoveries, testing discoveries and solving problems to seek new understanding, so as to encourage students' scientific reasoning which is one of the goals of education. Guided inquiry learning has an impact on students' scientific communication. The existence of findings beyond the previous estimate of the researchers, among others, counting on the class control class showed higher results compared to guided inquiry without scientific reasoning. The researcher assumed that the selection of control class classes was taken last which enabled the influence of the teacher as a model that brought the atmosphere of PBL activity and guided inquiry into the control class class. In addition, the possibility of students in the classroom control class has obtained information from the experimental class before doing research on control class class. Jiang, Clarke-Midura, Keller, Baker, Paquette and Ocumpaugh (2018) in his research shows that inquiry learning model is effective and efficient to implement science learning. The inquiry model involves a process that leads to asking questions, making discoveries, testing discoveries and solving problems to seek new understanding, so as to encourage students' scientific reasoning which is one of the goals of education.

Conclusions
The findings obtained from this study there are differences in scientific communication skills of students who learn to use the PBL model and guided inquiry that uses technology. There is influence of use of technology in the problem based learning model (PBL) to student scientific communication. The PBL model by providing video at the beginning of learning has a higher impact than the PBL model by providing early discourse to learning as well as PBL by giving a demonstration at the beginning of the lesson. In addition PBL video also gives the most significant impact on students' cognitive learning outcomes. There is influence of guided inquiry model to student's scientific communication. The inquiry model is guided by scientific reasoning giving higher influence than guided inquiry model without scientific reasoning.
