Comparison of Virtual Experiment Methods and Real Experiments Using Real World Problems in Improving Science Process Skills
Keywords:
Real Experiment, Real World Problem, Science Process Skills, Virtual ExperimentAbstract
Science Process Skills must be owned by a junior high school student, but the SPS owned by junior high school students is still relatively low. In an effort to develop the SPS owned by students, it is necessary to carry out experimental or observation activities. The experimental method itself is divided into virtual and real experimental methods, both of which have their own advantages and disadvantages in increasing students' basic SPS. Efforts to improve SPS can also link experimental learning with an existing problem. Therefore, a combination is needed using a problem, namely a real world problem. so that it becomes more effective in increasing SPS. The purpose of this study was to determine the comparison of the effectiveness of virtual and real experimental methods using real world problems in increasing the SPS of junior high school students. A quantitative approach was used in this study with a true experimental research type, a research design in the form of a pretest and posttest control group design was carried out in two classes VIII. Based on the independent t-test, a sig. value of 0.216 was obtained, indicating that there was no difference in the increase in basic SPS in the two classes. However, based on N-Gain (0.61 for virtual experiments and 0.52 for real experiments), it was found that both experimental classes were equally able to increase students' SPS with values that were not much different.
