In learning physics, the problem that arises is a lack of physics conceptual understanding in contextual learning. These problems are due to the absence of innovative and creative learning resources that can be used to learn by the students. One of the learning resources that can be used is a dictionary. moPhyDict (mobile physics dictionary) is a dictionary containing explanations of concepts and illustrations (images, videos, animations) in a language that is easily understood by students. This study specifically aims to test the effectiveness of Mobile Learning: moPhyDict to improve student’s physics conceptual understanding. The method employed in this study was a quasi-experiment design. The experimental design used a pretest-posttest control group design. The sample of the study was 60 students from senior High School, which divided into control group and experiment group. The instrument test in this study used conceptual multiple choice question. Based on the t-test on the control class and the experimental class, it can be inferred that there is a significance score of 0.031. These results are supported by data: (1) the average score of the ability to understand the concept of the control class who did not use moPhyDict increased from 37.4 to 55.46, and (2) the average score of the conceptual understanding of the experimental class who used moPhyDict increased from 40.87 to 74.33. It was concluded that moPhyDict is effective to improve physics conceptual understanding of High School Students.

The misconception of the Solar System topic is still found in students so that it becomes one of the obstacles in the learning process. The purpose of this study is to analyze the effectiveness of the implementation of Predict-Observe-Explain-Apply (POEA) learning to change the junior high school students' conception in the Solar System topic. Quasi-experimental research with the non-equivalent control group design was conducted in one of the private junior high schools in Bandung city. Samples were selected based on the test of the average significance of the pretest score of the population. Furthermore, 30 students of the experimental class and 32 students of control class were selected. The research instrument, which consisted of 15 four-tier diagnostic test questions about Solar System were used to collect data before and after treatment. The tests were analyzed quantitatively by using the Mann-Whitney statistical test to determine the significance of the difference in the acceptable conception changes (Acceptable Change) of students in the experimental class with changes in the conception of students in the control class. The results of the research show that the implementation of POEA learning is significantly more effective than POE learning in changing the conception of Solar System topic. The findings of this study can be an alternative for junior high school teachers in planning learning about the Solar System, especially in an effort to change students' misconception about the Solar System.
