The Influence of Learning by Smartphone to the Conceptual Science Knowledge and the Independence of Students ’ Learning at Junior High School

This study aims to determine the effect of using smart phone learning on science knowledge conceptual and independence of students’ learning in junior high school. The design of quadratic control groups is used on this research with all seventh grade students at SerangBanten City Junior High School as the population. The random technique samples are VII A grade as an experimental class and VII B grade as the control class, so it can be measured the conceptual science knowledge and scaling the independence of students’ learning by questionnaire. Independent sample T Test survey result shows using the smart phone has an impact to science knowledge with a significance value of 0.002 and an independence of student’s learning with a significance value of 0.003.


INTRODUCTION
Science or Science learning is very important to constantly be developed and analyzed.in terms of material and learning, science continues to experience change to become more extensive and complex.Science as a complex science is a science whose truth is derived from scientific activities both in the laboratory and in the surrounding environment.The activity was carried out to get a systematic theory that was used for general-natural phenomena.This is a big challenge for teachers to explore themselves with the aim achieve satisfying learning goals for students.
One of the way is by increasing creativity in transferring knowledge to students.
Based on the results of the Octavia study (2014) teachers need to improve their creativity in learning.This is because the creativity of the teacher is useful in stimulating students to think more scientifically in observing community symptoms or natural phenomena that are the object of study in learning. In

RESULTS AND DISCUSSION
Based on the results of data processing from mastery of the science concepts of junior high school students, the effect of smartphone usage in learning can be seen in Figure 1

Figure 1 .
Figure 1.Percentage of conceptual science knowladge of science in junior high school students in the control and experimental classes homogeneous.Furthermore, to find out the influence of the use of smartphones in calor concept the stages of sciencespecific knowledge are tested by testing the hypothesis of the data obtained.The results obtained, the significance value is 0.002 where the value is smaller than the significance level of 0.05, which means there is a difference in the value of conceptual knowledge of science between the control class and the experimental class.Based on the signification value, it is likely that there is an influence of the use of smartphones in learning calor concept on science conceptual knowledge.This can be because smartphones are effectively used in learning.Students become more enthusiastic in learning and the time used is more efficient.This finding is in line with the results of Firmawati (2014) study, which obtained the results of research that Smartphone usage has an influence on the fulfillment of learning resources and there is a functional and significant relationship between smartphone use and fulfillment of learning resources among students.Smartphones as learning media provide a big role in supporting ICT-based learning (Information and Communication Technology).Junior high school students have been able to find information through the website and share it with group friends or classmates.As stated by Rogozin (2012) the use of smartphones as learning media provides more in-depth learning opportunities for students.This is because with the use of smartphones students can develop learning through searching information from the internet, as well as practicing their skills in carrying out lab work because of the principle of mobility possessed by smartphones.Furthermore it was said that by using smartphones students were able to build their competence in a dynamic manner.Based on the results of data processing from student independence learning of junior high school students, the effect of smartphone usage in learning can be seen in Figure 2.

Figure 2. Percentage of learning independence of junior high school students in the control and experimental classes control class and the overall experiment are not homogeneous.Furthermore, to find out the influence of smartphone usage in calor concept learning, the stages of learning independence are by testing the hypothesis of the data obtained.The results obtained, the significance value is 0.003 where the value is smaller than the significance level of 0.05, which means there are differences in the value of student's learning independence between the control class and the experimental class.This is reinforced by the results of the observation that the experimental class looks more independent in looking for references during the learning process when compared to the control class.Searching information be easier and more efficient references via internet using a smartphone.As the results of the research byJohanes and Munthe (2014)
